Wits Gold Ltd Beisa North Technical Report
1. Executive Summary (ITEM 3)
Witwatersrand Consolidated Gold Resources Limited (Wits Gold a
company registered in South Africa and is an active mineral exploration
company with several gold and uranium prospects located in the
Witwatersrand Basin. Wits Gold is listed on the main boards of the
The Beisa North Project Area, situated immediately to the north of the dormant
Beisa Mine, is covered by two New Order Prospecting Rights granted to Wits
Gold in terms of the South African Mineral and Petroleum Resources
Development Act of 2002.
ExplorMine Consultants was commissioned by Wits Gold to complete a
Technical Report as per the Canadian National Instrument 43-101 F1 Form, in
support of its compliance with the Toronto Securities Exchange requirements.
The subject of the Technical Report is the Mineral Resource of the Beisa North
Project Area, Free State Province, Republic of South Africa. The Mineral
Resource estimation is based on historic borehole data collected since the late
197
This Qualified PReport is based on a technical review by ExplorMine
Consultants over a two month period in 2009. The effective date of the
Technical Report is the 30 th of June 2009.
1.1 Location and Property
The Beisa North Project Area is located at the south western end of the Free
State Goldfield. The Free State Goldfield is located within the auriferous
Witwatersrand Basin, approximately 300km south west of the city of
Johannesburg, along the south western margin of the known basin. The Project
Area is situated approximately 30km south of the city of Welkom, and
immediately north of the dormant Beisa Mine owned by Gold Fields Limited.
Welkom is the main centre servicing the Free State Goldfield.
Wits Gold is currently in possession of two New Order Prospecting Rights PR
486 and PR 494 in terms of Item 7 of the Mineral and Petroleum Resources
Development Act No. 28 of 2002.
1.2 Infrastructure and Environment
The Beisa North Project Area currently has no mining infrastructure developed
and therefore no historical mine production or statistics. However, the Beisa
North prospecting rights adjoin the historic Beisa Uranium Mine (later
renamed Oryx and then Beatrix 4 Shaft) that is currently situated on Beatrix
Gold Mine and operated by Gold Fields Limited.
The Free State Goldfield is characterised by mature Witwatersrand gold mines
x

Wits Gold Ltd Beisa North Technical Report
and the local industry has experienced a downscaling of operations due to
declining grades and ageing infrastructure.
1.3 History, Exploration and Mining
Geographically, Beisa North can be divided into two sectors by the westerly
flowing Sand River. To the south of the Sand River, the area was previously
prospected by Anglo American Corporation (1982-1991), where a total of 13
boreholes were completed. Two exploration targets were intersected, namely
overturned Ada May or Beisa Reef at depths of 640m to 1115m below surface
and the Kimberley 4 or Kalkoenkrans Reef at depths of 1650m to 2145m
below surface. The Kalkoenkrans Reef intersections were east and therefore
outside of the current Wits Gold Beisa North Project Area.
In the area to the north of the Sand River, a further 14 boreholes were
completed by Union Corporation mainly during the period 1977 to 1979 as
part of their regional exploration programme for the Ada May Reef. Although
some of these boreholes intersected the Ada May Reef at depths ranging from
450m to 1500m below surface, no resource estimate is available for this area.
The Ada May or Beisa Reef was mined by Gencor at the adjacent Beisa Mine
from 1982 to 1984. The reef was mined from approximately 380m to 1000m
below surface.

1.4 Geology and Mineral Resources
The Beisa North Project Area is located on the south western margin of the
Achaean Witwatersrand Gold Basin, which is located on the Kaapvaal Craton
in South Africa.
The Ada May or Beisa Reef occurs at the base Virginia Formation within the
Johannesburg Subgroup. The strata containing the Ada May Reef are
overturned with the sedimentary rocks of the Jeppestown Subgroup (of the
West Rand Group) form the hangingwall to the Ada May Reef, while the
Virginia Formation occurs as the footwall of the reef. Structurally the Ada May
Reef lies within an overturned synclinal fold with an axial plane which strikes
north-south.
The Ada May Reef varies from a 5cm thick quartz-pebble conglomerate to a
150cm thick unit comprising loosely packed quartz and chert clasts.
xi

Wits Gold Ltd Beisa North Technical Report
Commonly, a carbon seam up to 5cm thick occurs at the basal contact, and
carries most of the gold and uranium mineralisation.
Two sedimentary facies of Ada May Reef have been identified, namely the
Palmietkuil and Boschluispruit Facies.
The Mineral Resource estimate presented in this document for the Ada May
Reef is based on several sets of sampling data. These data were collected over
an extended period of time from the late 19
The data set includes surface boreholes represented by hard copy drilling logs,
geological plans and sections.
A re-evaluation of the Mineral Resources has been performed using the
geological database that was electronically captured. It is intended to produce
a three dimensional expression of the gold and uranium value distribution, so
that future exploration of the Mineral Resources can be planned efficiently.
Inverse Distance estimation was interpolated into a 3-dimensional geological
model, which produced a spatial distribution of grade estimates.
This Technical Report and the technical work on which it is based provide a
compliant Mineral Resource Estimate. A three-dimensional estimated block
model has been constructed and can be used as a tool to guide future
exploration and mining decision making.
A Mineral Resource has been declared as per the tabulation below. No Mineral
Reserve is declared.

1.5 Conclusions and Recommendations
The geological work conducted on the core and available data indicate that
there are two facies of the Ada May Reef present in the Beisa North Project
Area, namely the Palmietkuil and Boschluispruit Facies. The geological
evidence indicates that there is continuity of the Ada May Palmietkuil Facies
from the northern portion of the defunct Beisa Mine to the southern third of the
xii

Wits Gold Ltd Beisa North Technical Report
Beisa North Project Area. The physical characteristics of the two facies are
distinguishable from one another. The area in which the Palmietkuil Facies
occurs represents the more prospective area for uranium exploration and
eventual extraction.
It is suggested that a suitable exploration programme be designed to expand on
the current geological and geostatistical information, thereby providing data for
expanding on and upgrading the current Mineral Resource Estimate. The area
south of the Sand River corresponding to the occurrence of the Palmietkuil
Facies of the Ada May Reef appears to be most prospective and therefore
should be the focus of the planned exploration program for the Beisa North
area. Using the estimate at a suitable cut-off grade as a guideline, exploration
target areas within the Palmietkuil Facies area can be delineated. Strategically
placed boreholes and associated Ada May Reef intersections together with
existing intersections of the Ada May Reef will most likely achieve the desired
exploration and Mineral Resource Estimate results.
It is the opinion of the Qualified Persons that with further exploration and
assuming that favourable market conditions for the production and sale of
uranium and gold exist, the Beisa North Project Area has reasonable prospects
for eventual economic extraction.

Wits Gold. No additional legal due diligence has been applied. This is also the
case in terms of any environmental liability and any other claims on Wits Gold
and related parties.
4. Property Description and Location (ITEM 6)
The Beisa North Project Area is located at the south western end of the Free
State (or Welkom) Goldfield (Figure 2). The Free State Goldfield is located
within the auriferous Witwatersrand Basin, approximately 300km south west
of the city of Johannesburg, along the south western margin of the known
Basin. The property is situated approximately 30km south of the city of
Welkom, and immediately north of the dormant Beisa Mine owned by Gold
Fields Limited. Welkom is the main centre servicing the Free State Goldfield.
Figure 3 indicates the localities of relevant mining operations and exploration
properties.
Wits Gold is currently in possession of two New Order Prospecting Rights in
terms of Item 7 of the Mineral and Petroleum Resources Development Act No.
28 of 2002. Wits Gold has applied for and been awarded New Order
Prospecting Rights 30/5/1/1/2/486 PR (1470.71 ha) for uranium and gold and
30/5/1/1/2/494 PR (2277.32 ha) for gold only in respect of the Beisa North
Project Area and Beisa North Project Area extension west respectively, as of
the 8 th of April 2008 subject to certain terms and conditions.
Government-registered surveyors surveyed the surface areas occupied by the
Beisa North Project Area. Boundary beacons have local survey (Lo 29) and
World Geodetic System coordinates. In terms of the Prospecting Rights, the
boundary beacons are plotted on the Surveyor General and relevant mining
and
relevant boundary co-ordinates for each Prospecting Right.
The area which incorporates the prospecting and surface areas pertaining to the
Beisa North Project Area is located in the Free State Province, Magisterial
District of Virginia. The total surface area occupied by the Prospecting Rights
is 3748.03 ha.

Wits Gold Ltd Beisa North Technical Report
As far as ExplorMine Consultants could ascertain all relevant Prospecting
Right permits and any other permits related to the work conducted on the
property have been obtained and are valid.
4.1 Property Tenure
Following the promulgation of the Mineral and Petroleum Resources
hts and the
administration thereof were vested with the State. The MPRDA was subject to
transitional provisions in terms of which Old Order Rights have to be
converted to New Order Rights. This is not an automatic process and in order
to preserve its rights, the holder of Old Order Rights has to follow the process
and comply with the transitional provisions to the MPRDA. In addition the
prospective conversion applicant has to demonstrate that it in fact held a right
under the previous Minerals Act prior to the implementation of the MPRDA.
Where no previous mining or prospecting right existed or the holder of an Old
Order Right declines or neglects to convert the right to a New Order Right, the
right expires and a New Order Right application subject to all the relevant
provisions has to be lodged with the Department of Mineral and Energy
In this context it is understood that Wits Gold has been awarded New Order
Prospecting Rights 30/5/1/1/2/486 PR and 30/5/1/1/2/494 PR in respect of the
Beisa North Project Area (Figure 4) as of the 8 th of April 2008 subject to
certain terms and conditions. The Prospecting Rights are valid for an initial
period of five years with a subsequent renewal period of up to three years. To
the extent that certain rights and authorisations have changed according to the
requirements of the MPRDA, ExplorMine Consultants has relied on
information provided by Wits Gold that the permits are valid.
In terms of the legislation, prospecting must commence within 120 days of
being granted a Prospecting Right and prospecting must be conducted
continuously and actively thereafter. At the end of the eight-year period, a
Retention Permit may be granted for a period of up to three years with a single
additional two-year renewal period, subject to certain conditions. The
Retention Permit may only be granted after the holder of the Right has
established the existence of a mineral reserve while prevailing economic
conditions were not favourable for mining to commence. The MPRDA also
provides for a Mining Right that is valid for up to 30 years and can be
renewed for similar periods of up to 30 years.
The Minerals and Petroleum Resources Development Act (Act 28 of 2002)
was promulgated by the South African Parliament during July 2002 as the
MPRDA and came into effect on 1 May 2004. The intention of the MPRDA is
to make provision for the equitable access and sustainable development of the
opportunities for recognised empowerment exploration and mining companies.
22

Wits Gold Ltd Beisa North Technical Report
exploration and development.
Another important facet of the MPRDA is that it promotes holding of and
transfer of mineral rights in respect of Historically Disadvantaged South
transfer of ownership within the South African mining industry to HDSA over
the next few years (up to 2014). All stakeholders are obliged to achieve a target
of 26% empowerment status. In addition, the Mining Charter contains
employment equity targets of at least 40% HDSA participation in mining
company management within five-years, with 10% being participation by
women.
The Mining Charter requires a 15% Black Economic Empowerment stake
holding (at fair market value) by April 30, 2009, and an additional 11% by
2014. To this end, Wits Gold with 31% of its shares held by BEE shareholders
meets the required level of BEE equity holding in respect of any future Joint
Venture agreement and subsequent transfer of mining rights. The transfer of
equity to a BEE stakeholder is a requirement for the granting of a New Order
Right.
Wits Gold will retain the New Order Prospecting Rights if it maintains its
HDSA status, and adheres to the Work Programme submitted with the original
Right applications. The Work Programme includes environmental and social
compliance and a proposed exploration budget.
On 10 March 2003, a Royalty Bill was released for public comment. A revised
Mineral and Petroleum Royalty Bill was recently introduced by the South
African Government for comment. Comment on the Bill was open until
January 31, 2007. The Bill in its current form went before parliament during
September 2008 and was approved. The Bill imposes a royalty rate in terms of
a defined formula for refined and unrefined gold (or other mineral or
petroleum) not exceeding 5% and 7% respectively. The Minister of Finance
recently announced a deferment of the royalty until 2010. The Royalty Bill
may have an impact on the financial feasibility of any intended future mining
operations on the Beisa North Project Area. In terms of prospecting, the
Royalty Bill is not likely to impact on activities planned by Wits Gold.

4.2 Environmental Issues
Key environmental legislation, which is applicable to the South African mining
industry, is as follows:
National Environmental NEMA) as
regulated by the Department of Environmental Affairs and Tourism
DEAT) and relevant Provincial departments of environment.
MPRDA as regulated by the Department of Minerals and Energy. The
MPRDA replaces the Minerals Act, 1991 and makes provision for
mineral and petroleum resources. Regulations under the MPRDA set
out the procedures for undertaking Environmental Impact Assessments
EIA).
Minerals Act 1991 and the MPRDA make provision for transitional
arrangements. A mine must convert old order mining rights to new
order mining rights by the 31 April 2009. A key requirement for new
mines or for the conversion process is the need for a Social and Labour
SLP), a Mine Works Plan MWP), proof of technical and
financial competence as well as an approved Environmental
Management Plan (EMP).
Mine Health and Safety Act (Act 29 of 1996) as regulated by the DME
This Act deals with the protection of the health and safety of persons in
the mining industry but also has implications for environmental issues
related to environmental health monitoring within mines.
Other relevant legislation includes the following:
Department of
regulated by DEAT.
the DEAT, DWAF and relevant Provincial departments.
National Heritage Resources Act (25 of 1999) as regulated by South
departments where established.
Hazardous Substances Act (15 of 1973) as regulated by the Department
of Health.
ECA, Forest Act (84 of 1998), Provincial Nature Conservation Acts
and other Ordinances as regulated by Provincial conservation
authorities.
National Nuclear Regulator Act of 1999 as regulated by the National
Certificate of Registration (COR) system.
Environmental liability provisioning in the South African mining industry is a
requirement of the MPRDA and must be agreed with the relevant regulatory
25

Wits Gold Ltd Beisa North Technical Report
authorities (mainly the DME and the DWAF). For existing mines, monies are
accrued based on the estimated environmental rehabilitation costs should the
mine have to close and over the operating life of a mine. Contributions are
made to an environmental trust fund in this regard, which are approved by the
South African Revenue Service.
The intended Beisa North Exploration operations, sites and related
infrastructure are the subject of an Environmental Management Program
approved as part of the application for a New Order Mining Right by all
relevant interested and affected parties.
In compliance with Section 39(1) and Regulation 52 of the MPRDA, Wits
Gold has submitted an EMP to the DME as an integral part of the applications
for the New Order Prospecting Right that has been granted in respect of the
Beisa North Property. In order to provide security for the rehabilitation of drill
sites, Wits Gold has lodged a total of ZAR10, 000 in bank guarantees with the
DME in respect of each Prospecting Licence.
5. Accessibility, Climate, Local Resources, Infrastructure and Physiography
(ITEM 7)
5.1 Accessibility
The Beisa North Project Area is located approximately 30km south of the city
of Welkom, situated in the south western part of the Free State. This centre is
approximately 2.5 hours to 3 hours drive south west of Johannesburg via the
National N1, R34 and R30 roads.
The general area is well developed in terms of access, and mining related
infrastructure. Gold mining and related activities have been conducted in the
Free State Goldfield for over 50 years. Access to the Beisa North Project Area
is made by well-maintained paved road. The area also has well established rail
links and an airfield.
Wits Gold is allowed to utilise the surface of properties for which it has a
New Order Right, but only for activities necessary to prospect and mine
on the property.
5.2 Climate and Physiography
The largest part of the Free State Province comprises a gently undulating plain
ranging between 1000m and 1500m above mean sea level. The elevation of the
area immediately surrounding the Beisa North Project Area is approximately
1380m above sea level. Gold mining and agriculture (mainly cultivation) are
the main economic activities in the area.
Natural vegetation in the area typically consists of grassland with some trees
along watercourses.
26

Wits Gold Ltd Beisa North Technical Report
The climate is temperate and generally mild with temperatures averaging 23
degrees centigrade in the summer season from December to February, and 7.7
degrees centigrade in the winter from May to July. The area has a summer
rainfall averaging around 500mm to 600mm per annum. The winters are
generally very dry. Due to the underground nature of the gold mining
operations in the Free State, the climate has no effect on mining operations in
the area.
5.3 Resources and Infrastructure
The Free State Goldfield is characterised by relatively mature Witwatersrand
gold mines and the local industry has recently experienced a downscaling of
operations for economic reasons. As a result the supply of experienced skilled
and semi-skilled labour is abundant.
Electrical and water supply infrastructure is very well established in the Free
State Goldfield area. Electrical supply is generally provided through
agreements with Eskom (para-statal electrical service provider). Electrical
supply is not likely to be a limiting factor for new mining development on the
Beisa North Project Area.
Water is supplied from the Vaal River, through Sedibeng Water, a para-statal
organisation. It is believed that water supply to the Free State Goldfield is
unlikely to be a limiting factor in the future as most of the current mining
operations in the Free State Goldfield were planned with far larger production
than is currently the case. In addition, there are no large scale mining projects
currently being developed.
The Beisa North Project Area is located immediately north of the dormant
Beisa Mine. There is currently no mining infrastructure developed in the Beisa
North Project Area.
6. History (ITEM 8)
6.1 Exploration
Near Odendaalrus, some 11km north of Welkom, there occurs an inlier of
Ventersdorp conglomerate (Bothaville Formation). It was the similarity of
these conglomerates to those of the Witwatersrand Supergroup that focused
interest in this area and led to the subsequent discovery of the Free State
Goldfield. Prospecting on these conglomerates was first undertaken around
1890, with a vertical and incline shaft being started. This was, however, soon
abandoned with interest being revived in 1909 when promising gold values
were reported, possibly to maintain flagging enthusiasm, as no positive records
exist.
In 1933, mainly on the initiative of Allan Roberts, a dental mechanic and a
27

Wits Gold Ltd Beisa North Technical Report
dedicated amateur geologist, a diamond borehole was started on the farm
Aandenk, not far from the site of the earlier prospecting. This hole intersected
barren Ventersdorp conglomerates at 18m, and at 181m entered the lavas of the
Ventersdorp Supergroup. This was extremely discouraging, as available
information suggested that these lavas could be up to 1 829m in thickness as
calculated from the outcrops around the Vredefort Dome to the northeast.
Roberts, however, with infinite faith arranged to continue drilling,
impoverishing himself in the process. When the money finally ran out and the
hole was forced to stop, it was just 120m short of a payable intersection of the
Basal Reef having traversed low grade Eldorado and Kimberley Reefs.
Roberts, however, had succeeded in establishing that the Klipriviersberg Lava
was only 609m thick and was underlain by upper Witwatersrand rocks. Thus,
if any one factor must be singled out as the main cause of the discovery of the
Free State Goldfield, it must be the vision of Allan Roberts.
surveys (gravimetric) were undertaken despite being temporarily delayed by
the Second World War. In 1946 the Roberts hole, AA1 was deepened and the
Basal Reef intersected at a depth of 1353m. This hole was proclaimed a
National Monument in 1960.
The major mining houses such as Anglo American Corporation ,
Union Corporation and Johannesburg Consolidated Investments Limited
(JCI) soon acquired interests in the Free State Goldfield. Subsequent drilling
led to the proving up of the Basal and associated Leader Reefs as well as
establishing the A and B Reefs as secondary targets. The town of Welkom was
established and during the period 1951 to 1961 thirteen new mines were
brought into production. All of these were designed to exploit mainly the Basal
Reef.
The area south of the Sand River was first drilled for Witwatersrand
reefs by Union Corporation in 1938. However, once it was ascertained that
the principal economic target, the Basal Reef, subcrops mainly to the north of
the Sand River, the significance of scattered anomalous gold values in this
southern area was largely ignored. Further sporadic drilling was carried out
by a variety of companies over the subsequent thirty years but exploration
south of the Sand River was only fully revived in 1969 when Union
Corporation once again focussed their attention on this area. This strategy was
largely influenced by Union Corpofolded
Western Margin Structure of the Witwatersrand Basin as revealed
in underground mining at St Helena Gold Mine.
Union Corporation subsequently merged with General Mining and Finance
Corporation in 1980 to form Gencor and continued the drilling to the south of
the Sand River. During
southern Free State Goldfield, the first Beisa, was primarily a uranium mine
with by-product gold that exploited the Ada May Reef at the base of the
28

Wits Gold Ltd Beisa North Technical Report
Central Rand Group. Beisa commenced production in 1982 but was forced to
close in 1984 due to a weakening of the uranium price. The second mine,
Beatrix was established in 1980 with production primarily focused on gold
extraction from the Beatrix Reef. To the east of Beatrix, the H.J. Joel Gold
mine (subsequently named Joel Mine) owned by JCI entered production in
1986 and was later acquired by Anglo Gold Limited (formerly AAC) in 1998,
and then the Harmony - African Rainbow Minerals Joint Venture
in 2002.
Immediately to the east of the Beisa orebody, African Selection Trust
(AST) outlined a reserve on the Big Pebble Marker (BPM), locally
termed the Kalkoenkrans or Sand River Reef. The mine which came into
production as a result, known as Oryx, used the adjoining Beisa Shaft to access
the orebody. Oryx was later acquired by Gencor and integrated with their
Beatrix operation in 1998. In 1998, Gold Fields of South Africa and Gencor
merged to form GFL, which resulted in the
operational management of the Beatrix Mine being taken over by GFL.
In August 1994 AAC agreed to a full exchange of exploration data with
south of the Sand River. This agreement resulted in a re-interpretation of
the stratigraphy and structural geology. The investigation included the relogging
of 98 boreholes and incorporated data from the adjoining Beatrix and
Harmony Mines. The results of this investigation included the identification of
several zones of enhanced gold mineralisation on the VS5 or Beatrix Reef, the
Kalkoenkrans Reef (a facies of the A Reef), the B Reef and the Leader Reef in
the Southern Free State Goldfield. Despite these positive conclusions, no
further work was undertaken.
In November 2001, Anglo Gold Limited sold its Mineral Rights in this region
to the Harmony-ArmGold-Freegold Joint Venture. These Old Order mineral
rights were subsequently acquired from the Harmony Joint Venture by Wits
Gold on 30 April 2004.
The Beisa North Project Area Prospecting Rights adjoin the old Beisa Uranium
Mine currently situated on Beatrix Gold Mine that is operated by Gold Fields
Limited. Geographically, Beisa North Project Area can be divided into two
sectors by the westerly flowing Sand River. To the south of the Sand River, the
area was previously prospected by Anglo American Corporation (1982-1991),
where a total of 13 boreholes were completed. Two exploration targets were
intersected, namely overturned Ada May or Beisa Reef at depths of 640m to
1115m below surface and the Kimberley 4 or Kalkoenkrans Reef at depths of
1650m to 2145m below surface. The Kalkoenkrans Reef intersections were
east of the current Wits Gold Beisa North Project Area.
In the area to the north of the Sand River, a further 14 boreholes were
completed by Gencor mainly during the period 1977 to 1979 as part of their
29

Wits Gold Ltd Beisa North Technical Report
regional exploration programme for the Ada May Reef. Although some of
these boreholes intersected the Ada May Reef at depths in the range of 450m
to 1500m below surface, no resource estimate is available for this area.
6.2 Historical Mineral Resource and Reserve Estimates
In terms of Mineral Resources and Reserve estimates for the Beisa North
Project Area, a previous Estimate exists only for the area explored by the
Anglo American Corporation south of the Sand River. The Estimate presented
in Table 1 was completed by Anglo American Cor
based on 13 surface boreholes. This Estimate has not been declared publicly in
recent years, and should not be regarded as SAMREC compliant; it is
presented for information purposes only. It is problematic to compare this
Estimate to the current Estimate as little is known about the areas and data
which were used in the calculation. No historic Mineral Resource Estimate is
available for the area north of the Sand River within the Beisa North Project
Area.

6.3 Mining
The Beisa North Project Area currently has no mining infrastructure developed
and therefore no historical mine production or statistics. However, the Beisa
30

Wits Gold Ltd Beisa North Technical Report
North Project Area Prospecting Rights adjoin the old Beisa (later renamed
Oryx and then Beatrix 4 Shaft) Uranium Mine currently situated on Beatrix
Gold Mine that is operated by Gold Fields Limited. Beatrix 4 Shaft is currently
exploiting the Kalkoenkraans Reef which occurs stratigraphically above the
Ada May or Beisa Reef which is the subject of this Report.
Beisa Mine was brought into production by the former Gencor in 1982 as
first primary uranium mine to exploit the Ada May Reef which
has high uranium and low gold values. The mine was developed in response to
ces and sales volumes
collapsed from the early as a result of the international backlash against
nuclear power plants in the wake of the 1979 incident at the Three Mile Island
reactor in the United States.
The Ada May Reef was selectively mined at Beisa Mine from approximately
380m to 1000m below surface. The haulages extend over a strike length of
approximately 3.0km. Cross-cuts to reef are approximately 120m apart.
Historic production and current Mineral Resource is presented in Table 4.

The mining was for the most part conventional Witwatersrand breast mining
on narrow reef horizons, with typical mining layouts consisting of a cross-cut,
box holes and travelling (access) ways to the reef horizon. Stoping (on reef
mining) operations would have been conducted from an on reef raise, equipped
with mechanical scrapers for removing ore to the central raise. A mechanical
winch in the raise would have scraped ore into the box holes. The bulk of the
mining at the Beisa Mine was from shallow dipping stopes.
Ore was trammed from the box holes to the shaft ore pass infrastructure using
track bound diesel locomotives and then hoisted to surface. Historically all
underground exploration, sampling, development and on reef mining (stoping)
-
Beisa Mine was closed in 1984. The mine became a Gold Fields Limited asset
following the merger of the gold assets of the former Goldfields of SA and
Gengold.
The Beisa 4 Shaft facilities include a double drop shaft system with associated
gold treatment plant, which are being utilised at present to produce gold. A
decision to go back into the Ada May Reef workings, while also maintaining
gold operations on the Kalkoenkrans Reef, would require an upgrading of the
ventilation system for the mine. A capital outlay would be required to add an
31

Wits Gold Ltd Beisa North Technical Report
acid leach plant onto the "back end" of the existing gold plant.
in the
Witwatersrand Basin following the widespread closure of facilities by previous
big producers. AngloGold Ashanti produces about 900 tons/year of uranium
oxide and is presently increasing that capacity to 1,200 tons/year. AngloGold
Ashanti also now wholly-owns the Nufcor plant which carries out the final
upgrading to the yellowcake stage for all the uranium producers in South
Africa.
7. Geological Setting (ITEM 9)
7.1 Regional Geology of the Witwatersrand Basin
The Beisa North Project Area is located on the south western margin of the
Achaean Witwatersrand Basin, which is located on the Kaapvaal Craton in
South Africa. The Beisa North Project Area, like many Witwatersrand gold
mines, targets reefs within the Central Rand Group. The sedimentary rocks of
the Central Rand Group occur within an oval shaped basin, which has a long
axis through the Welkom area and Johannesburg. The Central Rand Basin is
superimposed on the West Rand Group or Lower Witwatersrand Basin, which
has a much larger aerial extent, both of which are situated on the Achaean
Kaapvaal Craton.
The Witwatersrand Basin has historically been mined in several major centres
namely the Central Rand (Johannesburg), East Rand (Boksburg - Benoni
Springs), Far East Rand (Nigel), South Rand (Balfour), Evander, West Rand
(Krugersdorp - Randfontein), Carletonville, Klerksdorp and Free State
(Welkom). These mining centres have been historically referred to as
loiting zones of higher gold concentration associated with one
or more conglomerate units within the Witwatersrand sedimentary
accumulation. All of these centres occur along the margin of the Central Rand
Basin (northern, north-western and western).
The Witwatersrand Sequence is subdivided into the West Rand Group (Lower
Witwatersrand) comprising an argillaceous to arenaceous sequence (up to
5000m thick), which is overlain by the Central Rand Group an arenaceous to
rudaceous sequence (up to 3000m thick). Gold production from the
Witwatersrand Basin has been exclusively from the conglomerates in the
Central Rand Group, deposited in alluvial fan and fluvial environments.
The origin of the gold mineralisation has been the source of debate for over
100 years. This debate has been historically divided between the syngenetic or
placer proponents and the epigenetic or hydrothermal model. The most widely
maintains that
placer gold grains were reworked or remobilised after burial.
The Witwatersrand Sequence is overlain by metamorphosed mafic to
ultramafic rocks and meta-sedimentary rocks of the Ventersdorp Sequence and
by the clastic and chemical sedimentary rocks of the Transvaal Sequence.
32

Wits Gold Ltd Beisa North Technical Report
Unmetamorphosed flood basalts and sediments of the Karoo Sequence cover
most of the Witwatersrand Basin including the Free State Goldfield.
The Central Rand Group of the Witwatersrand Basin has been subjected to
three main phases of deformation. Syndepositional compressional deformation
during Central Rand sedimentation, which resulted in the intra- and
interformational unconformities (Brink, 1986). Extensional tectonics during
and post Ventersdorp times resulting in the ubiquitous development of normal
and wrench faulting present throughout the basin (Stanistreet et al, 1986). After
the Transvaal Sequence was deposited, a high-strain event resulted in the
formation of folds, bedding sub parallel faults, and regional low-angle
cleavage (McCarthy et al, 1986).
7.2 Local Geology of the Free State Goldfield
The Free State Goldfield forms a triangle between the towns of Allanridge,
Welkom and Virginia. The area is host to several gold mines, all of which
produce gold from auriferous bearing reefs situated within the Central Rand
Group of the Witwatersrand Sequence.
7.2.1. Stratigraphy of the Free State Goldfield
The regional stratigraphy (Figure 5) can be subdivided as follows:
Karoo Supergroup
Immediately overlying the Ventersdorp lavas and locally the Ventersdorp
sedimentary units are sedimentary rocks of the Karoo Supergroup including
the basal Dwyka Tillite Formation and some coal measures of the Ecca Group.
Ventersdorp Supergroup
Within the Free State Goldfield, the Ventersdorp Supergroup can be divided
into the Pniel Group, the Platberg Group and the basal Kliprivierberg Group
consisting of alternating sediments, amygdaloidal and non-amygdaloidal
andesitic lavas, tuffs and agglomerates (Minter et al; 1986).
Witwatersrand Supergroup
The Central Rand Group of the Witwatersrand Supergroup has been divided
into an upper Turffontein Subgroup comprising the Eldorado, Aandenk and
Spes Bona Formations and a lower Johannesburg Subgroup comprising the
Dagbreek, Harmony, Welkom, St Helena and Virginia Formations.
Turffontein Subgroup
Eldorado Formation
This Formation is subdivided into three members, the Uitkyk, the Van den
Heeversrust and the Rosedale Members. The base of the Eldorado Formation is
unconformable. The Uitkyk Member consists of a polymictic coarsening-up
sequence with heterogeneous pebbles and cobbles of black, yellow and green
shale, as well as greenstones, porphyritic lava, chert quartzite and quartz. The
33

Wits Gold Ltd Beisa North Technical Report
Van den Heeversrust Member consists of a basal polymictic conglomerate
overlain by yellowish argillaceous quartzite. The Rosedale Member consists of
a basal conglomerate that may either be a polymictic immature conglomerate
(VS5) or an oligomictic quartz pebble conglomerate (Beatrix Reef), overlain
by immature dark grey, gritty quartzite.
Aandenk Formation
The Aandenk Formation is host to several auriferous conglomerate reefs viz.
the basal Big Pebble Reef and the A Reef (locally Kalkoenkrans Reef). These
placers occur with a sequence of khaki to brown argillaceous quartzites with
interbedded pebbly quartzites.
Spes Bona Formation
This is the basal unit of the Turffontein Subgroup that is unconformably
underlain by the Aandenk Formation. It consists of a basal polymictic
conglomerate which may have associated kerogen (carbon) known as the B
Reef, overlain by khaki-yellow coarse pebbly argillaceous quartzites with
polymictic conglomerate horizons.
Johannesburg Subgroup
This Subgroup comprises the Virginia, St Helena, Welkom, Harmony and
Dagbreek Formations and is represented mainly by 1500m of argillaceous
quartzites. The Subgroup comprises an upward fining sequence culminating in
a shale unit (Upper Shale Marker) representing a transgression or enlargement
of the depository.
Dagbreek Formation
The Leader Reef is a composite of oligomictic and polymictic conglomerates
and rests on an unconformity at the base of the Dagbreek Formation. This is
overlain by interbedded siliceous and argillaceous quartzites with lithic
fragments (Leader Reef Zone). There are approximately 80m of argillaceous
quartzites - the Dagbreek quartzite, between the Leader Reef and the
uppermost shale of the Upper Shale Marker.
Harmony Formation
This unit consists of a waxy quartzite member directly below the Leader Reef.
This quartzite is argillaceous with diamictitic texture and interbedded siliceous
quartzite channels (Siliceous Quartzite Member). It is underlain by khakiyellowish,
phyllitic shale, known as the Khaki Shale, which grades into
laminated dark grey arenaceous shale to the west and south-west, indicating a
more proximal position in the depository. This shale is generally accepted as
being indicative of a lacustrine transgression. Below the Khaki Shale lies the
most important gold-producing reef in the Free State Goldfield - the Basal
Reef represented by the Basal and Steyn placers.

Wits Gold Ltd Beisa North Technical Report
Welkom Formation
This Formation comprises some 250m of argillaceous quartzites, gritty and
subordinate pebbly quartzites, with a polymictic clast composition of yellow
silicified shales, green siliceous quartzites and black chert. This unit thins
from west to east with a corresponding grain size decrease. The base of this
Formation is marked by pyritic conglomerates up to 2m thick known as the
Intermediate Reef or UF4.
St Helena Formation
This unit is evident as a 300m sequence of alternating mature quartzites and
argillaceous, pebbly protoquartzites, with a distinct change from the khaki
yellow sericitic quartzites (LF1) of the underlying Virginia Formation to
coarse grained, light grey siliceous quartzites (MF4) at the base of the St
Helena Formation.
Virginia Formation
The Virginia Formation is up to 800m thick and is marked by a transition from
the underlying finer-grained Jeppestown Quartzites into an alternating
sequence of greyish green argillaceous quartzites with pebble lags. The first
pebble layer may contain carbon, known locally as the Beisa Reef. The Beisa
Reef is considered to be a correlative of the Ada May Reefs in the Klerksdorp
Goldfield.
7.2.2. Structural Setting of the Free State Goldfield
The Central Rand Group as it occurs in the Free State Goldfield is deformed in
a broad northerly plunging syncline, with smaller parasitic folds marking the
southern limit of the prospective Witwatersrand Basin. Compressive
deformation was responsible for active uplift along the western and southern
margins of the Goldfield that resulted in a complex series of superimposed
unconformity surfaces. Erosion of the footwall sequences caused the
incorporation of this detritus into the reefs overlying the unconformities.
The compressive deformation is also manifest along the entire western margin
of the Free State Goldfield as marginal folding which is commonly associated
with easterly verging thrust faults (the Rheedersdam Thrust Fault).
The northerly plunging fold has been off-set by later normal faults related to
the regional Platberg extensional event. Northerly striking normal faults of
Ventersdorp age are the dominant structural features of the Free State
Goldfield, the most significant being the De Bron Fault, which has a
relative down-throw of more than 1,000 m towards the west. A structure of
similar magnitude, the Virginia Fault, strikes north-north-eastwards.
35

Wits Gold Ltd Beisa North Technical Report
The Merriespruit Thrust Fault is a southerly-verging compressional structure
that has an effective vertical displacement of 50 m to 100 m to the east
of the De Bron Fault. However, the throw appears to decrease in magnitude
in a westerly direction, where it bifurcates into a series of smaller thrust faults.

7.3 Property Geology Beisa North Property
In the area south of the Sand River (locally referred to as the Southern Free
State Goldfield), the stratigraphic separation between reef horizons decreases
rapidly southwards, resulting in complex subcrop relationships. The discussion
below is focussed on the Ada May Reef and the structural setting of the old
Beisa Mine and adjoining Beisa North Project Area.
7.3.1. Stratigraphy
The Ada May Reef or Beisa Reef occurs at the base of the Johannesburg
Subgroup, and Virginia Formation (Figure 8). The strata are overturned with
the metasediments of the Jeppestown Subgroup (of the West Rand Group)
forming the hangingwall to the Ada May Reef horizon, while the Virginia
Formation forms the footwall of the reef.
In the Beisa North Project Area, the Ada May Reef subcrops to the east against
the Karoo Supergroup.
The Ventersdorp Supergroup is represented by the lower units of the
Klipriviersberg Group and is present only in the eastern portions of the Beisa
North Project Area.
The Karoo Supergroup has an average thickness of approximately 340m over
the entire Beisa North Project Area. A sporadically developed coal seam is
present, and in places a glacial tillite (Dwyka Group) occurs at the base of the
sequence. The Karoo Supergroup has been intruded by a large number of
dolerite sills and dykes.
7.3.2. Structure
Structurally the Ada May Reef lies within an overfolded syncline with an axial
plane (Figure 7) which strikes north-south and dips towards the west. The fold
axis has a gentle northerly plunge. The Ada May Reef dips vary within the
structure from very steep (45o to 80o) against the subcrop in the east,
flattening off to between 10o and 20o moving westwards and then steepening
further westwards into the fold closure . On Beisa Mine to the south, locally
reversed dips have been recorded. Folding appears to have affected the lower
stratigraphic horizons more than younger formations suggesting progressive
deformation. The Eldorado and Aandenk Formations overly footwall
formations with an increasing angle of unconformity westwards.
Faulting is generally north-south trending, parallel or sub-parallel to the
Central Rand margin. Both Central Rand age easterly verging thrust faults and
Venterdorp age normal faults can be recognised. Displacement on major
structural features is often in excess of 100m.

8. DEPOSIT TYPE AND MINERALISATION (ITEMS 10 and 11)
The Ada May Reef varies from a 5cm thick quartz-pebble conglomerate to a
150cm thick unit comprising loosely packed quartz and chert clasts.
Commonly, a seam up to 5cm thick occurs at the basal contact, consisting
almost entirely of carbon, carrying the bulk of the gold and uranium
mineralisation.
Two sedimentary facies of Ada May Reef have been identified, namely the
Palmietkuil and Boschluispruit Facies. The Palmietkuil Facies, which was
identified on the northern two thirds of the Beisa mine, usually comprises a
narrow (5cm-15cm), poorly-sorted, small pebble conglomerate with a thin
carbon seam at the base. Flyspeck carbon and disseminated pyrite are present
within the matrix of the conglomerate comprising the Palmietkuil Facies. The
upper contact of the Palmietkuil Facies with the Virginia Formation is usually
gradational.
The Boschluispruit Facies is known to occur over the southern third of the
Beisa Mine. Although the quartzite matrix of the Boschluispruit Facies is
mineralogically more mature, the quartzites comprising this facies are almost
indistinguishable from the immediately overlying Virginia Formation. The reef
is a poorly-packed, multi-layered, small-pebble conglomerate, with moderate
pyrite mineralisation. The Boschluispruit Facies is distinguished by the
absence of a carbon seam.
40

Wits Gold Ltd Beisa North Technical Report
Wits Gold geological staff studied the characteristics of the Ada May Reef
intersections from 7 surface boreholes originally drilled by AAC, within the
Beisa North Project Area to the south of the Sand River (Figure 10). These
boreholes all intersected overturned stratigraphy within the recumbent limb of
the north-striking western margin fold structure (Note that any reference to
vertical positioning or trend is in respect to the time of deposition and not the
current overturned position of the reef).
The Ada May Reef zone in all of the available intersections has a similar
lithological composition comprising one or two, well defined, stacked,
upward-fining depositional cycles.
The lowermost of these cycles grades upwards from a 4 cm to 30 cm thick
small pebble conglomerate into a light-grey, fine to medium grained
orthoquartzite, 25 cm to 50 cm thick. The basal conglomerate consists mainly
(90%) of quartz clasts with rare grey and black cherts. It is poorly sorted with
most clasts ranging in size between 5 mm and 15 mm with the odd larger clast
up to 28 mm in diameter. The matrix of the conglomerate is comprised of
siliceous quartzite with 3 to 5 % disseminated fine to coarse crystalline pyrite.
Fine pyrite may also line foresets within the overlying orthoquartzite. Carbon
is commonly present within the basal 5 cm
conglomerate, where it is associated with bedding parallel fractures. It varies
between multiple carbon seams to a few flyspecks (Figure 9).
The second depositional cycle starts between 30 cm and 50 cm above the basal
contact of the reef zone. This cycle generally comprises an erosionally based
10 cm to 30 cm gritty orthoquartzite with scattered very small (4 mm to 6 mm)
quartz clasts, that grades upwards into a medium to coarse-grained, slightly
lithic, siliceous protoquartzite. One exception is Borehole DHM1, where the
upper cycle has a loosely packed small pebble conglomerate at its base. Pyritic
foresets are typical of the lower portion of the cycle.
A number of sedimentary features, together with maximum scintillometer
readings and dip of bedding measurements as recorded from the seven
boreholes studied are contained in Table 3.

Wits Gold Ltd Beisa North Technical Report
From the above information the following conclusions can be drawn:
Maximum conglomerate development, as defined by the cumulative
conglomerate thickness, is generally thickest in the south (Figure 10).
However, conglomerate thickness shows significant local variation as
demonstrated by the changes in thickness between deflections in the same
borehole. The observed conglomerate development in the Ada May Reef at the
Beisa North Project Area is very similar to those thicknesses documented for
the Ada May Reef at Beisa Mine.
The maximum clast sizes do not conclusively show any systematic variation
across the project area and may be related to in-channel variations within the
same distal braided stream depositional system where small to medium clasts
dominate (Figure 10).
The Ada May Reef is invariably oligomictic, with no non-durable clasts
present. This clast assemblage again closely fits the descriptions of the Ada
May Reef at Beisa Mine.
While seam carbon dominates from MD1 southwards, flyspeck carbon is most
common in the northern part of the project area (Figure 10). The highest
radiation readings (Figure 10) as well as the highest uranium assay grades
closely correspond to the development of seam carbon, indicating that carbon
development is probably the primary control on the uranium mineralisation.
It is therefore recommended that for evaluation purposes the two carbon
domains be viewed as separate geozones with a soft boundary running eastwest
between MD1 and MD7. Both in terms of the lithological composition
and the observed carbon variations there is a strong likelihood that the carbon
seam facies in the south of the project area is a continuation of the Palmietkuil
Facies of the Beisa Mine (Figure 11), while the flyspeck carbon dominated
facies of the northern part of the project area may correlate with the
Boschluispruit Facies of the Beisa Mine (Muntingh, 2009).

9. Exploration and Drilling (ITEMS 12 and 13)
Anglo American Corporation,
carried out drilling programmes in the Beisa North area from 1977 until 1991.
Drilling contractors were used drill the surface boreholes.
The core logging and sampling protocols are considered to be robust for the
time period under review. Union Corporation/Gencor and AAC maintained
consistent standards over a period of time. The data were stored as follows:
Soft file containing the borehole log, covering the primary borehole and
deflections, usually with borehole deviation surveys
Soft file containing the borehole logs of the reef intersections, plus the
sampling and assay data. The assay certificates are usually included.
With reference to the sampling protocol of borehole core, the following
observations are pertinent:
Sampling was unbiased as the core was split along a cut line defined by
the low point of the bedding plane at the base of the reef zone.
Sample numbers and depths were marked on the retention half core.
The samples were submitted to the Union Corporation/Gencor Assay
Laboratory in Springs or Anglo American Research Laboratories
(AARL) in Johannesburg.
Not all assay certificates are available.
No check assaying has been carried out on the remaining AAC
borehole core stored by Wits Gold at the Potchefstroom core yard.
As was practice at the time no field blanks or field standards were
inserted with each sample sequence.
No QA/QC reports are available for data of this period.
No re-assaying of samples was carried out at a secondary laboratory.
It is not clear whether Assay Laboratories inserted internal standards in
each batch of samples.
No sample pulps remain
The number of deflections drilled per borehole varies over time
It must be noted that some data have been lost, specifically related to the Union
Corporation/Gencor boreholes as follows:
Complete borehole logs
Complete reef intersection logs and sampling/assay forms
Borehole deviation surveys
In some instances the only sampling/assay data for boreholes are full

Wits Gold Ltd Beisa North Technical Report
reef composite values
No record of sedimentary reef facies in the boreholes drilled to the
north of the Sand River
The composite values associated with the core sample were corrected for the
angle of intersection and recorded as true width intersections.
Much of the data related to the Union Corp boreholes were obtained from the
SOFS report and historical Beisa Mine plans. All of the AAC hard copy logs
are available and the AAC borehole core is stored at
Potchefstroom core yard.
The Union Corporation/Gencor and AAC data complies with acceptable
standards and norms of the time and are considered to be of sufficient quality
for use in Mineral Resource Estimates.
Interpretation of the exploration data is detailed in Section 8 and Section 16 of
this Technical Report.
10. Sampling Method and Approach (ITEM 14)
The Mineral Resource Estimate presented in this document for the Ada May
Reef is based on several sets of data. These data were collected over an
extended period of time from the mid through to present. The data set
includes, surface diamond drill holes represented by hard copy logs
(subsequently electronically captured), and geological structural interpretations
in the form plans and sections. Other data included sedimentological and facies
datasets compiled by Wits Gold.
10.1 Boreholes
Historic surface drilling took place mostly between the late 1970 and early
. A total of 29 surface exploration boreholes with associated reef
deflections were drilled in the Beisa North Project Area. AAC drilled 7
boreholes south of the Sand River and Union Corporation drilled 18 boreholes
north of the Sand River. Four surface boreholes were drilled in the northern
portions of the prospect area by unknown explorers. Details of all available
surface borehole data are presented in Appendix B.
In general, the drilling procedure for all surface boreholes drilled in the Beisa
North Project Area hole with several reef
deflections on reef horizons. The core was cut or mechanically split in half.
One half would be sent to the assay laboratory while the other half would be
retained.
Before sampling and subsequent to delivery to the core yard, the core was
checked to ensure 100% core recovery. It was established that the intersection
was complete and representative. If the core recovery was greater than 99%,
and there were no adverse geological conditions e.g. veins or faults, then the
intersection was considered to be representative.
47

Wits Gold Ltd Beisa North Technical Report
After the metre core depths were marked on the core, the intersection was
transferred to the angle iron stand. The core was then orientated so that the low
point of bedding was coincident with the edge of the angle iron. The cut line
defined by the low point of the bedding at the base of the reef zone, when
viewed as per convention from left to right in the direction of increasing depth,
was drawn parallel to the core. The core was then rotated through 90 degrees
and a line was then drawn parallel to the core, to define the retention half core.
Sample lengths were defined taking into consideration the following factors:
Minimum sample lengths per core diameter (usually >20cm)
Core angles
Existing core breaks
Core fractures
Significant pyrite mineralization, conglomerate or carbon seam
development
The core was sawn (earlier core was mechanically broken) in half on the cut
line, with one half submitted to the laboratory in sealed plastic bags with a
sample identification attached, and the second half (retention half) retained
10.2 Geological Plans and Sections
Historic 1:1000 reef structure plans were draughted for the Ada May Reef
throughout the Beisa North Project Area by the previous explorers. These
1:1000 scale reef structural plans typically included lines representing contour
elevations below datum (1828.8m above mean sea level), structural features
such as faults, folds, and the position of surface boreholes. A full structural reinterpretation
based on all historical interpretations and surface borehole data,
was affected by Wits Gold geological staff and stored electronically in the
Information System using ARCGIS version 9.1.
10.3 Channel Sampling and Assay Data
No underground channel sampling data exists in the Beisa North Project Area.

11.1 History of Laboratory Procedures
AAC and Union Corporation - ies
located in Johannesburg and Springs respectively. ExplorMine Consultants has
not carried out an audit on these Laboratories or any previous assay
installations.
11.2 External Quality Control System
11.2.1. Comments on Past Practices
Limited information is available in respect of past assay practices, although it
may be assumed that techniques were similar to those used in laboratories
presently. The principle laboratories used in the sample preparation and
assaying, were the General Mining Union Corporation (later Gencor)
Laboratory .
The QA/QC measures reflect common practice in the exploration industry
from the It can be appreciated that from the 1970
to the early and AAC placed considerable
emphasis on quality control of assay data from the Beisa North surface drilling.
This exploration took place prior to the introduction of the SAMREC reporting
code.
While the use of standards and blanks was not common practice during this
period, it can be accepted that the laboratory produced good quality data that
can be accepted as representative of the mineralisation sampled. The sample
preparation and analytical procedures are reliable and conform to industry
norms of the era.
12. Data Verification (ITEM 16)
12.1 Data Processing, Quality Control and Data Verification Procedures
12.1.1. Boreholes
During the compilation of the surface borehole data, all borehole and project
co-ordination points were converted to the Hartebeeshoek 94 projection. The
elevations are based on the standard South African Mine datum of 1828.797m
(6000 ft) above mean sea level.
A software package Datamine TM was utilised to plot, interpret and estimate the
project data. A transformation of collar co-ordinates was performed to
orientate the data correctly in the Datamine TM software. The Datamine TM X
value is the same as the Y value for the Lo31 System and Datamine TM Y
value is the same as the X value for the Lo31 System. Magnetic declination
was applied to all surface borehole downhole surveys adjusted according to the
year that the borehole was drilled. If no downhole survey data were available
for a surface borehole a -90 0 dip was applied. Boreholes with complete data
sets were desurveyed utilising the Datamine TM Desurvey option. The bulk of
50

Wits Gold Ltd Beisa North Technical Report
the borehole data consist of point data representing collar and reef intersection
data.
Boreholes with complete data sets were desurveyed utilising the Datamine TM
Desurvey option. The bulk of the borehole data consists of point data
representing collar and reef intersection data. Many boreholes drilled in the
areas peripheral to the Beisa North area were also included in the total
database. The total number of boreholes included in the database was 134. A
total of 61 Ada May Reef intersection composites were available for
geostatistical and estimation purposes, while 80 boreholes were used for
structural interpretation only. A total of 59 boreholes in the database contained
both composite assay and structural information.
12.1.2. Geological Plans
The geological reef contours and associated geological structure as interpreted
by the Wits Gold geological staff were imported into Datamine TM . This
structural interpretation was used as a basis for the three-dimensional
geological modelling process. No transformations were applied to this data.
During the data processing and verification phase, a number of additional
surface borehole data were added to the total data set. These additional data
were not necessarily included in the initial Wits Gold geological
interpretations.
12.1.3. Total Data File
A combined data set consisting of surface boreholes was created. This
composite file served as the base data file for the geostatistical process. All the
data comprise composite data and has been corrected for dip. True width has
been accounted for.

12.2 Nature of and limitations on Data Verification
12.2.1. Boreholes
The surface borehole data at the Beisa North Project Area comprise both hard
copy logs and electronically captured data as collated by the Wits Gold
Geologists and ExplorMine Consultants. Where present, the assay logs also
have original assay laboratory returns. A number of borehole logs and assay
logs were missing entirely and certain assumptions were made in respect of the
data. All the geological logs that were captured were provided by Wits Gold
staff.
12.2.2. Geological Plans
A digitising procedure for electronically capturing the data from 1:20000 scale
geological plans and sections was used. There is a margin of error on the final
electronic coordination due to the errors inherent in the digitising process. This
error is not significant given the dimensions of the ore body.
A visual verification of the digitised data in Datamine TM was sufficient.
13. Adjacent Properties (ITEM 17)
The Beisa North Project Area is located in the well established Free State
Goldfield and is adjacent to several mines and exploration properties. Of most
significance to the Beisa North Project Area is the dormant Beisa Mine located
immediately south of the Project Area.
Underground production from Beisa Mine when it was in operation during the
sourced from the shallow dipping tabular narrow (less than
1m) Ada May Reef. Several geological structures complicated mining layouts,
whilst the reef dips typically at 20º to 25º, increasing to some 40º in certain
areas.
Information with respect to Beisa Mine is available through various sources
including, amongst others, public disclosures on the Gold Fields Limited
website, McCarthy T.S (2006), Greathead C. and Graadt van Roggen J.F.
(1986) and Tweedie K.A.M., (1986).
The Qualified Persons have been unable to verify the information and the
information is not necessarily indicative of the mineralisation on the Beisa
North Project Area that is the subject of this Technical Report.
Based on the currently planned life of gold mines in and around the towns of
Welkom, Virginia, and Odendaalsrus, the area is likely to remain a mining
centre for the next 20 to 30 years. Associated mining services are therefore
likely to be readily available for the foreseeable future.
14. Mineral Processing and Metallurgical Testing (ITEM 18)
The metallurgical processing conducted at the dormant Beisa Mine provides a
guide to possible metallurgical process for any future Beisa North uranium and
53

Wits Gold Ltd Beisa North Technical Report
gold production.
Run-of-mine ore from the mine was fed to mills. Thickened slime from the
mill thickeners was pumped to the uranium leach batch agitators where
sulphuric acid was added and manganese slurry was added as an oxidising
agent to ensure complete dissolution of all uranium compounds present in the
ore. The leached slurry was filtered by vacuum on horizontal belt filters to
separate the uranium solution from the remaining solids.
This solution was then clarified in hopper clarifiers, followed by sand clarifiers
and pumped to a solvent extraction plant. Extraction into the solvent phase was
achieved by emulsifying the water and kerosene in the extraction
mixer/settlers. The emulsion was then settled, the water layer separated and
then discarded. The solvent, containing all the uranium, was scrubbed clean
with fresh water and entered the stripping settlers. The clean uranium solution
was precipitated with ammonia, thickened, centrifuged and repulped with fresh
water to obtain ammonia di-uranate slurry. This slurry was shipped by road
tanker to a refinery.
The solids cake discharged from the belt filters was repulped and pumped to
Gold Leach batch agitators. The leached slurry was pumped to the carbon-inpulp
adsorption plant. This section used activated carbons to extract the gold
directly from the slurry. The pulp leaving the last stage was residue, and was
pumped to a slimes dam. The loaded carbon was sent to the elution columns
where the gold was dissolved.
The gold (and silver) was recovered from the cyanide solution by
electrowinning on to stripping electrodes. The metal sheets were removed and
melted into gold bars which were despatched to a refinery.
15. Mineral Resource Estimate (ITEM 19)
15.1 3D-Geological Modelling
A three dimensional geological wireframe model representing the Ada May
Reef and surface topography, using Datamine TM software, has been
constructed for the Beisa North Project Area. The model is based on the
geological interpretation affected by the Wits Gold geological staff. The
interpretation was adjusted locally to conform to surface borehole information
as rendered in three dimensions. This model represents the first comprehensive
geological model for the combined project area.
15.1.1. Structure
The regional structural and geological styles were propagated from the known
geological styles recorded at Beisa Mine located south of the project area. Due
to the relative sparsity of data points, it was also necessary to simplify the
interpretation to honour major structural features only.
The individuals involved in the structural modelling have extensive experience
in the structural style that occurs in Witwatersrand Basin localities.
54

Wits Gold Ltd Beisa North Technical Report
A representation of the final three-dimensional geological wireframe model is
presented in Figure 13.
15.1.2. Stratigraphic Modelling
Two surfaces were wireframed in Datamine TM as follows:
Surface topography
Base of Ada May Reef
A digital terrain model was utilised in the creation of most of the surface
topography wireframe. While conventional wireframing techniques were used
to construct the Ada May wireframe surface.
15.1.3. Block Model Creation
A block modelling process was undertaken to allow resource estimation of the
Ada May Reef in Datamine TM Studio 2. All data files, geostatistical data and
resultant models are stored at Wits Golds offices in Potchefstroom and on
compact disc. The Beisa North area was divided according to the recognised
reef facies into a northern Boschluispruit and southern Palmietkuil Facies. This
division was guided by the interpretation of the Wits Gold geologists.
The area was further divided according to reef attitude. An axial line parallel to
the fold axis was constructed and used to divide the block models into
ck
model cells (Figure 14). The block model extends to a depth of 2500m below
mean surface elevation. Although it is known that the Ada May Reef extends
to depths below this level, the paucity of data is a limiting factor. In addition
2500m is also the limit of design for a single drop vertical shaft.
Model parent cell size is 120x120x1(m), subcells were allowed for filling the
estimate into Parent Cells. Discretisation of 6 x 6 x1 was applied for the
estimate.
Block model zones for each facies (north and south), with the corresponding
inclined and vertical blocks were individually filled with blocks according to
the classification as described above. This methodology prevents model cell
overlaps.
The estimation data points were rotated into each respective average reef plane
domain to facilitate correct spatial data relationships for the estimation. A final
3-dimensional block model was populated utilizing inverse distance to the
power 2. The entire wireframe domain models were then added together and
their cell sizes adjusted according to the stoping width relevant per parent cell.
The following logic was applied to the stoping width calculation, if a channel
width was less than 1m then a 100cm stoping width was applied.

15.2 Mineral Resource Estimation Summary of Geostatistical Process
A complete re-evaluation of the Mineral Resources has been performed based
on the database that has been captured. It is intended to perform an evaluation
that will give a spatial expression of value distribution in three dimensions, so
that exploration of the prospect area can be planned efficiently. The estimation
has been conducted by Dr W.D. Northrop (BSc (Hons), MSc, PhD, GDE,
Pr.Sci.Nat., FGSSA, FSAIMM) who is independent of Wits Gold and any of
its associated entities.
Since there were no large expansive areas of close spaced sampling data
available to perform spatial geostatistical analysis, it was decided to approach
the evaluation in the first instance with a classical geostatistical method to gain
an appreciation of the global value of each of the two facies. This was then
followed up by a spatial analysis utilizing the cut-offs determined by the
classical analysis.
The mean grades of the two methods are compared. The total tonnage of each
mineralised body was obtained from the block models produced from the
wireframes.
15.2.1. Classical Statistics
Distributions on the overall database were attempted on the composites. Due to
the fact that only composite samples were available, there were insufficient
samples to discern whether any outliers occur. It is assumed that the individual
samples were not cut for outliers before composites were calculated. The same
observation can be said for the lower part of the distribution which cannot be
studied without the individual samples.
For the purposes of delineating the lateral limits of the mineralised zones in
this first pass evaluation, the composite values are accepted as the true limits of
the mineralised zone. The southern Palmietkuil facies (over folded) and
northern Boschluispruit (over folded) facies were evaluated separately as being
geologically of different character.
The mean of all the composites were calculated using Sichel T calculations
which are designed to calculate the mean of a small population of samples that
are log normally distributed. To do this exercise an additive constant Beta is
calculated which corrects for divergence from log normality. The Beta value is
allowed for in the final calculation of the mean value obtained. Thereupon a
grade-tonnage curve is calculated using the mean grade and the logarithmic
variance. The cut off value is then found which gives a permissible grade for
compliant declaration purposes with the attendant percentage tonnage. Results
for the classical statistics and Sichel T calculations are given in Table 5.
15.2.2. Spatial Evaluation
The next stage was to estimate into the three-dimensional block model. This
was done in Datamine TM using Inverse Distance methodology with a search
radius of 1000m and a minimum of two samples being accessed for each
block. There was no limit placed on the maximum number of samples as the
57

Wits Gold Ltd Beisa North Technical Report
inverse distance method of giving more weight to the nearest samples prevents
a global average being created for every block. Blocks further away from the
samples were estimated by doubling and tripling the search radius distance.
Therefore the model could be interrogated for three classes of Inferred Mineral
Resource in increasing confidence from SVUCMKGT = 3.0 to 1.0. For
calculating the Mineral Resources for compliant declaration purposes the cutoff
grades (cumulative) found classically above were applied to the grades
estimated spatially. Estimates were run iteratively varying the estimation
parameters until the tonnages and grades at cut off agreed with those calculated
classically.
Plots of the block model estimates (Figures 16-20) are shown as value plots of

15.3 Reconciliation
For the purpose of comparison between the classical results and the spatial
evaluation, the first search volume results of the inverse distance squared were
utilized as being more diagnostic.
Although the classical overall mean grades compare fairly well with the overall
mean grades of the block models, the classical grades above cut off are higher
than the equivalent declaration compliant block model cumulative value (26%
Boschluispruit Facies and 24% Palmietkuil Facies), due to the fact that the
variance of the raw data is much higher than the variance of the estimated
blocks. For this reason the grades of the block models are taken for the purpose
of reporting at the respective cut offs, because they are more conservative.
The correlation coefficients of the regressions between uranium cumulatives of
the data and the estimated values of the inverse distance at search volume 1 are
quoted below for the two facies as an indication of the reliability of these
estimates.

Table 7: Mineral Resource estimate for the Ada May Reef in the Beisa North Project
Area to a maximum depth of 2500m below surface. A U 3 O 8 cut-off of 50cm.kg/t has
been applied. (Values have been rounded off to the appropriate level of accuracy.)
Although the Mineral Resource estimate was completed using channel width
and corresponding content value, a realistic mining width has been applied to
the resource blocks to calculate a realistic in-situ mining grade. Similarly the
tonnages have been adjusted. Tonnage has been reduced through a geological
loss adjustment of 20% to account for minor fault loss as only large scale
structures have been accounted for in the geological modelling.
Sedimentological features are also accounted for in the geological loss
adjustment. An average specific gravity of 2.70t/m 3 has been applied in the
calculation of tonnage, consistent with the known bulk density from adjacent
mining operations.
As uranium is regarded as the primary mineral of interest for the Beisa North
Area, gold would be a potential secondary by-product of mining. A cut-off
grade value of 50cm.kg/t has been used for the uranium reporting as calculated
using pay limit calculations, which yielded a grade value of 82cm.kg/t and the
resultant grade-tonnage curve (Figure 21). Gold is reported only where the
uranium reporting cut-off of 50cm.kg/t has been exceeded.

16. Other Relevant Data and Information Interpretation (ITEM 20)
No other data or information is of relevance to this report.
17. Interpretation and Conclusions (ITEM 21)
The Mineral Resource Estimate presented in this document for the Ada May
Reef is based on several sets of data. These data were collected over an
data set includes surface boreholes represented by hard copy drilling logs,
geological plans and sections.
A re-evaluation of the Mineral Resources has been performed based on the
geological and sampling database that has been electronically captured. It was
64

Wits Gold Ltd Beisa North Technical Report
intended to perform an evaluation that would give a spatial expression of
uranium and gold value distribution in three dimensions, so that the exploration
of the Mineral Resources could be planned efficiently.
This Technical Report is intended to fulfil two basic objectives:
To compile a NI43-101 compliant Mineral Resource Estimate for the
Ada May Reef in the Beisa North Project Area.
To guide management in the identification of potential exploration
target areas by providing a spatial expression of the estimated Mineral
Resource.
The geological evidence indicates that there is continuity of the Ada May
Palmietkuil Facies from the northern portion of the defunct Beisa Mine to the
southern third of the Beisa North Project Area. The geological work conducted
on the core and available data indicate that there are two facies of the Ada May
Reef present in the Beisa North Project Area, namely the Palmietkuil and
Boschluispruit Facies. The physical characteristics of the two facies are
distinguishable from one another. The area in which the Palmietkuil Facies
occurs represents the more prospective area for uranium exploration and
eventual extraction.
Inverse Distance estimation was affected into a 3-dimensional geological
model, which produced a spatial distribution of grade estimates. An Inferred
Mineral Resource of 27.913Mt at 0.78kg/t giving 47.84Mlb of uranium has
been estimated for the Beisa North Project Area to a depth of 2500m below
surface at a 50cm.kg/t cut-off.
18. Recommendations (ITEM 22)
At the Beisa North Project Area surface borehole intersections of the Ada May
Reef are about 800 meters apart. Regularized closely spaced data on the same
reefs over an extensive area large enough to generate regularized variograms
with ranges of 800 meters or more are required. Such data are available on the
same reef at the defunct area of Beatrix 4 Shaft currently owned by Gold Fields
Limited that will enable evaluation through co-kriging and macro kriging. Wits
Gold should endeavour to acquire the channel sampling data from Gold Fields
Limited.
If the close spaced mine channel sampling data cannot be acquired, the Beisa
North Project Area should be drilled on a grid of approximately 400m by 400m
to achieve an Indicated Mineral Resource status and to close the spread in
confidence limits to below 25%. Ideally each mother borehole should have a
minimum of 6 reef deflections.
It is suggested that a suitable exploration programme be designed to expand on
the current geological and geostatistical information, thereby providing data for
expanding on and upgrading the current Mineral Resource Estimate. The area
south of the Sand River corresponding to the occurrence of the Palmietkuil
Facies of the Ada May Reef appears to be most prospective and therefore
should be the focus of the planned exploration program for the Beisa North
65

Wits Gold Ltd Beisa North Technical Report
Area. Using the estimate at a suitable cut-off grade as a guideline, exploration
target areas within the Palmietkuil Facies area can be delineated. Strategically
placed boreholes and associated Ada May Reef intersections together with
existing intersections of the Ada May Reef will most likely achieve the desired
exploration and Mineral Resource Estimate results.
It is important that the exploration programme is designed with stringent
quality control and assurance programmes in place. Future surface drilling
should be guided by the three-dimensional estimated block model.
It is the opinion of the Qualified Persons that with further exploration and
assuming that favourable market conditions for the production and sale of
uranium and gold exist, the Beisa North Project area has reasonable prospects
for eventual economic extraction.

21. Additional Relevant Information with Reference to the Exploration Property
(ITEM 25)
21.1 Mining Operations
Mining operations at a future Beisa North Mine are likely to be similar to those
employed by previous operators of the Beisa Mine, and similar to methods
presently employed at most conventional Witwatersrand gold mines. A rock
engineer will provide design input during future detailed feasibility work. Use
will be made of tools such as numerical analyses to optimise designs where
necessary. Rock mechanics will be particularly important in the planning
process at a future Beisa North Mine due to the complexity of the geological
structure as it relates to the attitude of Ada May reef. Mining and process
volumes, tonnages and grades would be considered during pre-feasibility and
feasibility work.
It is likely that a new metallurgical plant, would have to be commissioned by
Wits Gold should feasibility studies indicate that production is viable.
21.2 Recoverability
The modifying factors in terms of recovery of uranium and gold mineralisation
are likely to be similar to the historic factors as recorded at Beisa Mine. These
factors should be applied to the Beisa North Project Area for the declaration of
Mineral Reserves during any future Feasibility Studies.

Contracts or arrangements, rates or charges relating to mining, concentrating,
smelting, refining, transportation, handling, sales and hedging and forward
sales contracts, are most likely to be within South African Gold Mining
industry norms and practices. Currently no contractual arrangements exist as
the project is still in an early exploration stage. There are currently no legal
proceedings which will impact on the right to explore.

21.5 Environmental Considerations
No mining infrastructure exists on the Beisa North Project Area. The nearest
mining infrastructure owned by Gold Fields Limited adjoins the Beisa North
Project Area and is located approximately 2km to the south. Additional impact
on the environment should occur as additional mining infrastructure such as
shafts, dumps and slimes dams are planned and developed. The Beisa North
Project Area lated infrastructure would be the
subject of an Environmental Management Program approved as part of the
New Order Mining Right which will be granted at some future date pending
positive financial feasibility for the project.
In compliance with Section 39(1) and Regulation 52 of the MPRDA, Wits
Gold has submitted an EMP to the DME as an integral part of the applications
for the New Order Prospecting Rights that have been granted in respect of the
Beisa North Property. In order to provide security for the rehabilitation of drill
sites, Wits Gold has lodged ZAR10, 000 in bank guarantees with the DME in
respect of each Prospecting Licence.
21.6 Taxes and Royalties
The South African government is also contemplating the enactment of a
Mineral and Petroleum Royalty Bill. This bill would have been implemented
from 1 May 2009; however the Minister of Finance recently announced a
deferment of the royalty until 2010. An allowance for a royalty payment
should be included in any future feasibility studies on this basis.
21.7 Capital and Operating Cost Estimates
Wits Gold has a work programme for the Beisa North Project Area which
includes a desk top study and an initial drilling programme comprising 2
surface boreholes to be drilled between December 2009 and March 2010. The
budget for the initial exploration programme is approximately R4.01 million.
Further exploration will be dependent on the results of this programme.
Except for the monies spent on the prospecting licence applications no funds
have been expended on exploration activities to date by Wits Gold.
The proposed work programme will take more than two years to execute.
ExplorMine Consultants considers the proposed exploration plan and budget as
adequate for the intended exploration results.
21.8 Economic Analysis
Wits Gold may undertake formal Pre-Feasibility and Feasibility Studies
dependent on market conditions as well as the outcome of planned exploration
and any revised Mineral Resource estimate on the Beisa North prospect to
determine its economic feasibility.
