51 SUMMARYProperty Description Chambe Basin is part of <strong>Malawi</strong> Exclusive Prospecting Licence 0325/11,a rectangular block about 40 km E-W and 27 km N-S with an area of 1,050 sq km, within whichthe licencee has exclusive rights to prospect for rare earths (“REE”) and bauxite.Location The Property is located in southernmost <strong>Malawi</strong> (south central East Africa) andcovers the Mulanje Massif. The centre of the Property is at approximately 15˚ 57”S, 35˚ 37”E.Ownership EPL 0325/11 is held in the name of Spring Stone Limited, a private <strong>Malawi</strong> companythat is a 100% subsidiary of Spring Stone Exploration <strong>Inc</strong>., a private company registered in BritishColumbia and a 100% subsidiary of Canadian public company <strong>Gold</strong> <strong>Canyon</strong> <strong>Resources</strong> <strong>Inc</strong>. Theproject is a joint venture between <strong>Gold</strong> <strong>Canyon</strong> <strong>Resources</strong> <strong>Inc</strong>, and Japan Oil, Gas and MetalsNational Corporation (“JOGMEC”), which provides 67% of funding for Spring Stone Exploration<strong>Inc</strong>. and consequently has a 67% equity option holding in licence-holder Spring Stone Ltd.Geology A gneissic basement complex of Precambrian to Lower Paleozoic age forms the oldestrocks in the area. This is intruded by a series of partly overlapping, subcircular, mostly syeniticplutons that are part of the Chilwa Alkaline Province, of Upper Jurassic to Lower Cretaceous age.Chambe Basin is an area of low relief covered by thick, bouldery, residual kaolinitic soils in themiddle of one of these syenite intrusions that is surrounded by a circular outer rim of bare syenite.Mineralization A small number of reconnaissance samples of soils collected in 2010 and early<strong>2011</strong> from Chambe Basin and analysed for leachable rare earths (“REE”) suggest there ispotential for a bulk REE deposit in these soils.Exploration concept Chambe Basin is being explored for a REE deposit of the “ion adsorption”type. Such deposits are quite important REE producers in China but few have been foundelsewhere. Typically the REE content is low, but a significant part is easily extractable by ionexchange using dilute solutions of common chemicals such as ammonium sulphate. Othercharacteristics include very low U and Th, a large proportion of high value “mid” and “heavy” REE,and they may be mined by relatively inexpensive shallow surface excavations or in situ.Status of exploration The Property licence was acquired on 18 March of <strong>2011</strong>, mostly on thebasis of reconnaissance samples by Geological Survey Dept headed by J. Ishikawa in 2010. Anexploration program of systematic short-hole drilling, with some pitting, initial environmentalsampling, and analysis of soils for leachable REE is currently being carried out by Mitsui MineralDevelopment Engineering Co. Ltd (“MINDECO”) under contract to Spring Stone Exploration <strong>Inc</strong>.,the vehicle for the joint venture between <strong>Gold</strong> <strong>Canyon</strong> <strong>Resources</strong> <strong>Inc</strong> and JOGMEC.Conclusions and recommendations Only a small number of reconnaissance samples of soilsfrom the Chambe Basin have so far been analyzed, but from review of these and verifyinganalyses the author agrees with the interpretation by J. Ishikawa, JOGMEC and MINDECO thatthere is potential for a REE deposit of the ion adsorption type. A US~$1.1 M program proposed byMINDECO, and accepted by the <strong>Malawi</strong> Government, is currently under way. While the authorhas had no opportunity to recommend changes to this approved program he endorses it as a welldesignedand thorough first phase plan of exploration of the Chambe Basin for ion-adsorptionREE potential.

7Relationships between companies involved in the <strong>Malawi</strong> project are shown in Figure 1.Chambe Basin lies within Exclusive Prospecting Licence EPL 0325/11 (the “Property”) in theMulanje Mountain area of southern <strong>Malawi</strong>, also referred to as the Mulanje Massif. This licencewas initially granted in March of <strong>2011</strong> to the Japan Oil, Gas and Metals National Corporation(“JOGMEC”). JOGMEC is a semi-governmental corporation of the Japanese Government, withoffice address 2-10-1, Toranomon Minato-ku, Tokyo, 105-0001, Japan. Subject to a then-existingagreement between <strong>Gold</strong> <strong>Canyon</strong> and JOGMEC, at the request of JOGMEC and with the assentof <strong>Gold</strong> <strong>Canyon</strong>, the <strong>Malawi</strong> Government agreed to transfer Licence EPL 0325/11 to SpringStone Limited, a limited private company incorporated in Blantyre, <strong>Malawi</strong> under the Governmentof <strong>Malawi</strong> Companies Act on 15 th June <strong>2011</strong> with registration number 11406. The office addressof Spring Stone Limited is c/o Sacranie, Gow and Company Legal Practitioners, Realty House,Churchill Road, PO .Box 5133, Limbe, <strong>Malawi</strong>. Spring Stone Limited, an indirect wholly-ownedsubsidiary of <strong>Gold</strong> <strong>Canyon</strong>, was formed to acquire and maintain the Property and other propertiesin <strong>Malawi</strong> and to facilitate mineral exploration and development in <strong>Malawi</strong>.Spring Stone Limited is a wholly-owned subsidiary of Spring Stone ExplorationLimited, an indirect wholly-owned subsidiary of <strong>Gold</strong> <strong>Canyon</strong> (with the same office address)formed for the purpose of managing the <strong>Malawi</strong> project and is the operator of a joint venturebetween <strong>Gold</strong> <strong>Canyon</strong> and JOGMEC to explore for REE in <strong>Malawi</strong>. Details of this joint venture arecontained in a Project Venture Agreement (“PVA”) between JOGMEC, <strong>Gold</strong> <strong>Canyon</strong>, SpringStone Limited and Spring Stone Exploration <strong>Inc</strong>. dated September 13, <strong>2011</strong>, but effective onNovember 14, the date of transfer by the <strong>Malawi</strong> Government of EPL 0325/11 from JOGMEC toSpring Stone Limited. Under the PVA JOGMEC has the option to acquire a 67% interest in the<strong>Malawi</strong> Project and <strong>Gold</strong> <strong>Canyon</strong> 33%. Some details of the PVA are contained in a news releaseon September 8 of <strong>2011</strong> by <strong>Gold</strong> <strong>Canyon</strong>, which is available on their website. This PVAsupersedes a 2009 joint venture agreement between JOGMEC and <strong>Gold</strong> <strong>Canyon</strong> to explore forrare earth resources, initially in the USA and more recently in <strong>Malawi</strong>, through private USAcompany <strong>Gold</strong> <strong>Canyon</strong> Kratz Springs LLC.Exploration on EPL 0325/ 11 will be carried out by Mitsui Mineral DevelopmentEngineering Co. Ltd (“MINDECO” ) a wholly-owned subsidiary of Mitsui Mining and SmeltingCo of Japan under a Technical Service Agreement with Spring Stone Exploration <strong>Inc</strong>. (Figure 1).

16(d) Ownership, surface rights, legal access, obligations, expiration date.The Chambe Basin lies within the Mulanje Mountain Forest Reserve and the mineraland surface rights are owned by the Government of the Republic of <strong>Malawi</strong>. Licence EPL0325/11 permits exclusive rights to carry on prospecting operations for rare earth elementsand bauxite. Legal access is by public roads and paths administered by the LikhubulaForestry Office of the Department of Forestry .Obligations assumed by licence-holder Spring Stone Ltd include the carrying out ofthe exploration program for rare earths and bauxite as proposed in the licence application(Anonymous (<strong>2011</strong>), Anonymous (<strong>2011</strong>a), Kojima (<strong>2011</strong>), Kojima (<strong>2011</strong>a). The originallyproposed expenditure of US $2.5 million was later reduced to US$1.0 million. Theexploration program was designed and will be carried out by Mitsui Mineral DevelopmentEngineering Co (“MINDECO”) under contract to Spring Stone Exploration <strong>Inc</strong>. Phase I ofthis program is to be carried out in fiscal year <strong>2011</strong> and consists of systematic shallowdrilling and pitting in Chambe Basin, with analysis and testing of soils for recovery of rareearths. Environmental observations will also be made.Conditions specified in the licence include requirements to commence operationswithin 3 months of granting of the licence, to supply quarterly progress reports and annualreports, to annually report the proposed program and budget for the next year’s work, toemploy and train <strong>Malawi</strong>an citizens, to use goods and services from <strong>Malawi</strong> wheneverpossible, to conserve the environment, and to reclaim and restore areas damaged byexploration activities. Any shortfall from the proposed expenditures is considered a debt tothe Republic of <strong>Malawi</strong>.The Licence was granted on the 18 th day of March of <strong>2011</strong> for a period of 3 years, withan option to renew the Licence in accordance with Section 50 of the <strong>Malawi</strong> Mines andMinerals Act 1981.(e)Royalties, back-in rights, payments, agreements, encumbrancesThe joint venture between JOGMEC and <strong>Gold</strong> <strong>Canyon</strong> concerning a program forexploration of minerals in <strong>Malawi</strong>, defined as the “<strong>Malawi</strong> Project”, is detailed in a ProjectJoint Venture Agreement (”PVA”) made on September 13 of <strong>2011</strong> between JOGMEC, <strong>Gold</strong><strong>Canyon</strong>, Spring Stone Limited and Spring Stone Exploration <strong>Inc</strong> and effective on November14 of <strong>2011</strong>, the date of reassignment of Exclusive Prospecting Licence 0325/11 from


17JOGMEC to Spring Stone Limited by the Government of <strong>Malawi</strong>. Some details of thisagreement are contained in a news release made on September 8 of <strong>2011</strong> by <strong>Gold</strong> <strong>Canyon</strong>and available on the <strong>Gold</strong> <strong>Canyon</strong> website.Among other provisions and conditions of the PVA the <strong>Malawi</strong> Project is defined toinclude EPL 0325/11 and any other properties that may be acquired in <strong>Malawi</strong>. JOGMECholds the option to acquire 67% equity interest in the <strong>Malawi</strong> Project, which may beconverted to a proportionate shareholding in any Joint Venture formed from the <strong>Malawi</strong>Project. <strong>Gold</strong> <strong>Canyon</strong> holds the option to acquire 33% by contributing to the PVA. The PVAalso addresses matters such as conversion to net smelter royalty interests of 1.5% if dilutedto


18drill) and the other a small portable diesel-powered drill (YBM-05). Drilling will be mostlydry, chemicals will not be used, drill-sites should have minimal disturbance and holes willbe backfilled. Topsoil from pits and trenches will be stripped and replaced when backfilled.Accommodation will be in existing huts with piped water supplies. The Joint Venture hasretained a biologist familiar with the area to ensure environmental issues of the currentexploration are monitored. In the author’s opinion the environmental impact of the currentexploration will be insignificant.However, the Chambe Basin lies within the Mulanje Mountain Reserve, which wasestablished in 1927, and environmental issues for any eventual mining operation areimportant. Although mining can apparently proceed within this reserve, development mustbe done in a way that conserves the environment, especially water catchment areas suchas the Chambe Basin. There is also now an interest in eradicating introduced plants suchas the Mexican pine, Himalayan raspberry and the Australian eucalyptus and in replantingthe native cypress. Clearly, it is too early to consider the impact of any eventual mine butthe Joint Venture has proposed that it might be possible to combine restoration of a minedarea with reforestation of the basin with cypress.The Mulanje Mountain Conservation Trust was founded in 2000 with funding by theWorld Bank for research and conservation of biological diversity and promotion ofsustainable use of natural resources in the Mulanje Mountain Forest Reserve. It hasadvocated removal of introduced flora and restoration of endemic species, particularly theMulanje cypress, and has lead opposition to proposed mining of bauxite from the MulanjeMassif, principally on the Lichenya Plateau. While solution extraction of REE from soils inChambe Basin has little in common with the stripping and removal of large tonnages ofbauxite, environmental issues of REE resource extraction if it affected streams or createddust, etc. will need to be considered.(g) Work permitsNo work permit is required for the current work on the Joint Venture, but approvalwas required by the Ministry of Environmental Affairs before this work began.If the project proceeds to a second phase (in 2012) an Environmental Impact Study(“EIS”) will need to be initiated. Should the project eventually prove feasible the EIS willneed to be completed and a “Mining Licence” from the Ministry of Natural <strong>Resources</strong> would


19be required, and also a “Licence to Operate in a Forest Reserve” from the Ministry ofForests.(h) Other significant factors and risks affecting access, title, and ability to performwork.In the author’s opinion there are no significant factors and risks affecting access andability to perform exploration for REE in the Chambe Basin. Although the Property covers aforest reserve, exploration and mining within the reserve is apparently possible. However, ifa mine proves feasible it is clear that environmental impacts will be closely scrutinized andthe benefits to the local community and to <strong>Malawi</strong> will be weighed against environmentalrisks of development.5 ACCESSIBILITY, CLIMATE, LOCAL RESOURCES, INFRASTRUCTUREAND PHYSIOGRAPHY(a) Topography, elevation and vegetationThe Mulanje Massif rises steeply above the densely-populated surrounding Chilwa-Phalombe Plain at 650-750 m to Mt Sapitwa at 3,002 m, the highest peak in south-centralEast Africa. The massif is covered by the Mulanje Mountain Forest Reserve and contains adiverse and partly endemic vegetation, particularly the once more common MulanjeCypress, (Widdringtonia whytei) which became scarce by the 1950’s due to logging. TheMulanje Cypress is one of 4 African Widdringtonia species of the Family Cupressaceae andis often erroneously referred to as a “cedar”, which belong to the Family Pinacea and areunrelated to cypresses. A smaller cypress (Widdringtonia Nodiflora) and gladioli, groundorchids, proteas, aloe, crysanthemum, ferns, mosses, wild peach, yellow wood and otherplants are also present. Lists of some of the 6 endemic trees, the 66 mammals, 300 birds,31 snakes, 25 lizards, 33 frogs, 233 butterflies and 7 fish known from the Mulanje ForestReserve can be found in Deppe and Bishop (2010). Introduced plants include the MexicanPine (Pinus patula), eucalyptus and the Himalayan raspberry.The floor of the Chambe Basin has a rolling, subdued topography (Figure 6, 7, 9)ranging from about 1,690 m at the southern lip to about 1,875 m and is surrounded by acircular rim, partly of bare rock ( Figure 6, 7), which rises to a maximum height of 2,557 mat Chambe Peak. Chambe Basin apparently was once covered by a forest of the Mulanje


20Cypress, but few of these trees remain there today and the basin was later planted inMexican pine and most of this has also now been logged. The basin today has only a thincover of small bushes and grasses (Figure 6, 7).(b) Means of accessChambe Basin can be reached from Blantyre by vehicle on a good sealed road ESEabout 1 hour to Chitikale Village and then east a few km to the road end at the LikhubulaForestry Station by a gravel road, which passes through Nakoya Village. Several footpathslead to Chambe Basin from the lower southern slopes, the main one being the SkylinePath, which begins at the Likhubula Forestry Station at about 835 m and climbs to thesouth rim of the basin at about 1,690 m and takes 2 to 3 hours. From this point the footpathcontinues across the approximately 3.5 km wide basin and connects with a network of dirtroads that lead to several forestry / tourist huts.The present access to the property by footpaths is clearly insufficient for anysignificant mining activity and would need to be improved. In the past a cable-way, whichruns for about 2.1 km from a short road above the Likhubula Forestry Station to the UpperSkyline Station on the south rim of the basin, was used to bring logs down from the basin.The load bearing cables (about 1.5 inch) are still in place and, if the project continues, thecable-way might be re-activated or replaced and used to transport materials and perhapspeople to and from Chambe Basin. It is understood the Joint Venture will evaluate thisoption and any other access possibilities if the first phase of the project is encouraging.(c) Proximity to population centres, nature of transportThe nearest population centre to the Chambe Basin is Nakoya Village in thelower Likhubula Valley, where many mountain porters live, about 8 km SW of the basin.Chitikale, the commercial centre of the Mulanje district, lies a few km west of the LikhubulaForestry Station and the small town of Mulanje is about 9 km to the south on a paved road.Blantyre, the largest town (population ~730,000) and main commercial centre in <strong>Malawi</strong>,lies about 60 km in a direct line to the WNW.


21(d) Climate, length of operating seasonThe climate of <strong>Malawi</strong> is hot and wet from November to April, cool and dry fromMay to August and hot and dry from September to October. Annual rainfall is very differenton the Mulanje Massif (>100 inches) than on the surrounding plains (~40 inches). Rain mayfall at higher elevations at any time of the year, although it is more frequent and intenseduring the wet season. Intermittent rain and mist centred on the massif is common.Temperatures on the Phalombe Plain range from about 15˚ to 35˚C but on the massiftemperatures are generally lower, especially at night, and in June and August may dropbelow zero and snow may fall occasionally at higher elevations.Conditions may be more difficult in the wet season, but exploration and miningoperations could continue throughout the year.(e) Sufficiency of surface rights, availability of mining operationinfrastructure, areas for tailings, waste, leach pad areas and plantsSurface rights are owned by the Government of <strong>Malawi</strong>. There is very little mininginfrastructure in <strong>Malawi</strong>, mostly quarrying operations, and mining equipment wouldprobably need to be brought from South Africa or from outside Africa. The only significantmine in <strong>Malawi</strong> is the Keyelekera uranium mine, which opened in 2009. The World Bank(Land and others (2009)) identified unreliable power and transport as significantimpediments to developing mining operations in <strong>Malawi</strong>.At the present preliminary stage of exploration no study of areas for tailings, waste orplants has been made or is warranted.6 HISTORY(a) Prior ownership and ownership changesPrevious interest in the mineral resources of the Mulanje Mountain area hascentred on their extensive bauxite deposits, developed by weathering mainly on the Linjeand Lichenya plateaux at elevations of 1,800 -2,000 metres (Garson and Walshaw (1969)).According to Garson and Walshaw (1969) and Anonymous (1994) the bauxite depositswere discovered in 1924 and have been explored by various companies, including the


22Anglo American Corporation (1934, 19<strong>43</strong>), the British Aluminium Co. (1951-1958) and, onbehalf of the <strong>Malawi</strong> Government, Lonrho (1969-1973)..According to Chimwala (2009) in 2001 BHP Billiton considered developing theMulanje bauxite for their Mozal Smelter in Mozambique, and in 2005 South Africancompany Gondo <strong>Resources</strong> was granted an exclusive prospective licence over about 29 sqkm covering Mulanje bauxite. This licence expired in 2008, and although the companyrequested an extension until Sept 3 of 2010 to produce a feasibility study and anenvironmental impact assessment, this was rejected in January of 2010. There has beenconsiderable opposition to this project, especially because of the possible effects of duston the important tea-growing area near Mulanje, on water sources flowing from the MulanjeMassif, and on further loss of the Mulanje Cypress by surface stripping, mainly on theLichenya Plateau. .(b) Nature, extent and general results of previous exploration.No exploration is known to the author from the Chambe Basin prior to the analysesby Ishikawa and MINDECO described in Item 7b. These two reconnaissance samplingprograms consist of a small number (25 samples in total) of mainly roadside samples andanalyses indicate some samples contain easily-leachable REE.According to Garson and Walshaw (1969) there is negligible bauxite in the ChambeBasin, but as noted above significant bauxite resources have been found on other areas ofthe Mulanje Massif within EPL0325/11. A study of feasibility of development of the Mulanjebauxite on these other areas was made by Met-Chem (Anonymous (1994)) on behalf of theMineral Investment Development Corporation (MIDCOR), acting for the Government of<strong>Malawi</strong> and funded by the African Development Bank. They recommended development ofbauxite (for aluminum) at a mining rate of 589,000 TpA, that an aerial tramway beconstructed to transport the bauxite to the plains below, and construction of a 200,000 TpAalumina plant. They also recommended that an aluminum smelter should not be built in<strong>Malawi</strong>, but instead that a commitment be sought from the aluminum smelter at RichardsBay in South Africa to purchase Mulanje alumina.

23(c) Significant historical mineral resources or reservesUsing the Lonrho data Met-Chem (Anonymous (1994)) reported a resource of 25.6MT of bauxite, using a cutoff grade of 30% Al 2 O 3, with an average grade of <strong>43</strong>.3% Al 2 O 3 .However, it must be clearly stated that this historical resource is not <strong>43</strong>-<strong>101</strong>compliant, it is not relied upon in this report, and it is not of exploration interest to<strong>Gold</strong> <strong>Canyon</strong>. More specifically, the bauxite resources, whatever their size or economicpotential, are not germane to the potential REE resources of the Chambe Basin that are thepresent interest of <strong>Gold</strong> <strong>Canyon</strong> on the Mulanje Massif.(d) ProductionThe author knows of no mineral production from the Property.7 GEOLOGICAL SETTING AND MINERALIZATION(a) Regional, local and Property geologyThis part of southern <strong>Malawi</strong> (Figure 8) is underlain by a basement complex (Garsonand Walshaw, 1969) consisting of folded and metamorphosed rocks of Precambrian toLower Paleozoic age, mostly paragneiss, but also including granulites, calcareous gneiss,marble, several types of amphibolite and varieties of mostly migmatitic and anatecticgranite.Intruding the basement complex are rocks of the Chilwa Alkaline Province of UpperJurassic to Lower Cretaceous age. The major alkaline rocks are a series of overlappingsub-circular intrusions of mainly syenite, some quartz syenite and granite that form theMulanje Massif, an inselberg (Figure 5) that rises high above the surrounding plains.The Chambe ring structure (Figure 5, 9) is one of several syenite complexes of theMulanje Massif and is about 8.5 Km across. The outer ring dike syenite(s) form aprominent bare rock rim (Figure 6, 7) that encloses a basin about 3.5 km across withinwhich a central syenite plug has recessively weathered to soils that are up to about 15 mthick and contain scattered syenite boulders (Figure 6, 7) , probably residual joint-boundedblocks (“core stones”). Leachable rare earths in these soils are the main target of the


current exploration begun in August of <strong>2011</strong> under the direction of H. Harada of MINDECOon behalf of <strong>Gold</strong> <strong>Canyon</strong>.24(b) Mineralized zones, rock types, controls, length, width, depth and continuity ofmineralization. Description of type, character, and distribution of mineralization.The REE mineralization in the Chambe Basin is so far known only from a very smallnumber (total 25) of soil and rock samples collected on several days of reconnaissancesampling, mostly from road cuts along old forestry tracks. The controls on mineralizationand the vertical and horizontal extent of the mineralization are therefore unknown atpresent, and the principal objectives of the current exploration program of systematicdrilling and detailed sampling being carried out by MINDECO are to document the REEmineralizedmaterial and investigate the distribution of the REE in the soil profile, the sizeand grade of any resource, and the recoverability of the REE.An indication of the size of the soil mantle over the central syenite plug in ChambeBasin is given by the work of Garson and Walshaw (1969, Plate X), who mapped the basinand described the soils from 69 pits ranging in depth from 5 feet to 50 feet (1.5 to 15.2 m).A contoured map of thickness of the soils from the pit data reported by Garson andWalshaw (1969) is shown as Figure 10. Garson and Walshaw described the deposits asmainly kaolinitic, with bauxite only in small patches, and the following summary of the soilprofiles is derived from their account (with inferred standard soil horizons A to C added).Weathered rock (C soil horizon?) immediately above the bedrock syenite plug maypreserve the texture of the parent syenite, may also contain fragments of feldspar,amphibole and biotite and is mainly white, with pink, yellow and black mottling. The mottlingincreases upward and red, pink and purple colours predominate, and in the upper parts (Bsoil horizon?) the soil is red-brown and only quartz from the weathered syenite survives. Ayellowish-brown subsoil is locally present and the uppermost soil (A soil horizon?) containshumus and is dark grey to black and rooty.The possibility that the Mulanje Mountain area might contain REE deposits of theion-adsorption type was proposed by Ishikawa (2010), a geologist from the JapanInternational Cooperation Agency currently working with the Geological Survey of <strong>Malawi</strong> inZomba. Ishikawa collected 8 samples (Table 2) from Chambe Basin in September of 2010.


25The following year, on May 22-23 of <strong>2011</strong>, a group of 7 geologists from MINDECO,JOGMEC and the Geological Survey of <strong>Malawi</strong> collected 16 samples at 9 sites (Table 3)including 13 soil samples from 6 sites and 3 rocks.It should be noted that only a small number of samples have been analyzed so far,that these are scattered over a large area, and that most are shallow (generally less than 3m) relative to the deep soils (Figure 10) reported by Garson and Walshaw (1969).Analyses (Table 4) of 3 “kaolinitic” samples (Table 2) collected by Ishikawa indicatedthese soils contain from 475 to 739 ppm total REE of which 31% to 74 % is easilyleachable(41% to 86% if Ce is excluded). Subsequent “weathered rock” samples taken byMINDECO, JOGMEC and Geological Survey of <strong>Malawi</strong> were found to contain (Table 5 and6) between 198 and 642 ppm total REE, and recoveries by leaching were in the range 0.1to 30% (38% if Ce is excluded), with 8 of 13 samples having 5% or less of their total REEleachable. This high variability of recovery of REE and the lower % of recovery than theIshikawa samples was considered by JOGMEC as possibly due to natural variability orperhaps to differences in leaching chemistry or methods between the earlier analyses(Nittetsu Lab) and the later analyses (Mitsui Lab). However, as an inter-laboratory checktwo original Ishikawa samples were leached by the Mitsui Lab and these show fairagreement in % of leached REE (see Table 7, 66% vs 74% for CHA-4 and 56 % vs 70% forCHA-6). This result suggests the methods produce comparable results and therefore implya fair degree of natural variability. These analyses show that Ce is 13 to 32% of the totalREE in the soils, but only 1 to 16% of the leachable REE, suggesting that Ce occurs in adifferent form than other REE, an observation that is consistent with studies of ionadsorption deposits elsewhere.Samples were collected by the author from Chambe Basin on 22-23 of August of<strong>2011</strong> from 11 sites (Table 8) for verification purposes and are discussed in Item 12. Manyof these samples were taken as checks at sites originally sampled by Ishikawa, and theauthor is also grateful to J. Ishikawa for providing 3 of his original samples for re-analysis(see Table 9 under Item 12). Re-analysis of these samples has essentially confirmed hisinitial reports that the Chambe Basin may contain a REE deposit of the “ion-adsorption claytype “.

8 DEPOSIT TYPESThe type of REE deposit being explored for in the Chambe Basin iscommonly referred to as the “ion-adsorption clay type”, although various othernames have been used including “south China type”, “Jiangxi rare earth ores” ,“weathered crust elution-deposited rare earth ores”, “MEX-REY ores”, and “ionicREE ores” . The following summary is taken from a number of sources, includingBao and Zhao (2008), Chi (1988), Chi and others (2005) , Chi and Tian (2008),Ishihara and others (2008), Kanazawa and Kamitami (2005), Maksimovic andPanto (1996), Morteani and Preinfalk (1996), Murakami and Ishihara (2008),Orris and Grauch (2002), Sanematsu and others (2009), and Wu and others(1996).Ion adsorption type REE deposits are fairly common in China, where theywere first discovered in the 1970’s, and now number at least 214 deposits (Baoand Zhao (2008)), but are almost unknown elsewhere in the world. About 90% ofthe Chinese ionic deposits are in the southern provinces, principally Jiangxi,Guang Dong, and Guang Xi, but also in Hunan and Fujian. These areas aregenerally subtropical areas south of 28˚ N with warm, humid conditions andannual rainfalls exceeding 1,500 mm. In these areas they generally develop inthe weathering zone where topography is gentle, denudation rates are low butlong-continued, and soils are consequently deep and well preserved. Mostappear to have formed by in situ weathering of granite, but some have developedby weathering of other igneous rock types (eg pyroclastics), and rarely even fromother types of rock (eg phyllite). There is also evidence from clays washed intokarst depressions in eastern Europe (Maksimovic and Panto (1996)) that REEconcentrations can develop in clays not formed in situ.Whatever the environment, REE enrichments of the ionic type appear tobe due to continuous ground water leaching that mainly decomposes accessoryREE minerals in soils, and to a lesser extent trace REE in rock- forming minerals,from the upper soils . The REE are progressively leached in upper layers andredeposited at greater depths. In China it appears the REE are mostly looselybound to clays, However, in soils developed on REE-bearing carbonatites inBrazil (Morteani and Preinfalk (1996) the REE may be mainly held in phosphates,


35(such as apatite or the barium aluminum phosphate gorceixite ), or in REEfluorocarbonates of the bastnäsite group. Less is known of the leachability ofthese minerals but it likely is less than the ionic clay type.Weathered soil profiles in the REE deposits of south China are of lateriticcharacter and range from 5 to 30 m depth, are generally 8-10 m thick but maylocally reach as much as 60 m (Chi and Tian (2008) , Bao and Zhao (2008)).Typically there is a surface layer of organic soils (A soil layer), a stronglyweathered clayey, grey, yellow to red coloured layer (B soil layer) which usuallyhas the highest REE enrichment, and a lower pale-coloured layer with remnantsilicate minerals in clay (C soil layer) that may also retain primary igneoustextures (“saprolite”).About 60 to 90% of the total REE are adsorbed on clays such as kaoliniteand halloysite (Chi and Tian (2008)).The grade of raw ore is between 0.05 % and0.35% total RE oxides but there is considerable variability (2 to 6 times) in gradewithin a single deposit, commonly with better grades on ridges than gullies. Thedeposits are relatively small, generally 3,000 to 12,000 tonnes but the annualoutput from this type of deposit from China is about 10,000 tonnes REE oxideaccording to Bao and Zhao (2008). According to Chi and Tian (2008) “provenreserves of RE are approximately 1.48 million tons” in ion-adsorption deposits,inferior only to the resource at Bayan Obo.This type of deposit is important as providing a significant proportion of midand heavy REE in China. Figure 11 shows the REE distribution in two importantChinese ion-adsorption deposits (Longnan and Xunwu) compared with threecarbonatite-related REE deposits Mountain Pass REE Mine, the Bayan Obo REEMine and the Mt Weld REE deposit. Individual ion-adsorption deposits vary intheir distribution of the REE but Figure 11 shows some characteristic features.The carbonatite deposits have a high proportion of light REE, while the ionicdeposits have low light REE, higher mid and heavy REE. They also commonlyshow a distinctive deficiency in Ce and sometimes in Eu. The Ce deficiency hasbeen explained (eg Bao and Zhao , 2008) by the tendency of Ce to oxidize fromCe 3+ to Ce 4+ , the formation of cerianite or absorption of Ce on Fe and Aloxyhydroxides .


36The ion-adsorption REE deposits can only be processed chemically.Extraction is by ion exchange using a variety of common chemicals such as thesulphate, nitrate or chloride of ammonium, which provide the NH 4+ cations toreplace REE ions, but Na+, K+ and other cations are also effective. The REEmay be extracted by batch-leaching, by heap-leaching or can be extracted by insitu leaching (“ISR”). The leached REE are commonly recovered from theleachate by precipitation with oxalic acid or ammonium bicarbonate.The principal features of the ion-adsorption REE deposits are summarizedbelow1 The REE deposits are soils developed in tropical areas with high rainfall bylong-continued weathering, generally on granite bedrock.2 Much of the REE is derived from weathered accessory minerals, naturallyleached by ground waters in the upper soils (A layer) and redeposited at greaterdepth where it is loosely bound to clays, generally in the B soil layer but also inthe C layer.3 Although ion-adsorption deposits vary in their composition of individual REE,they tend to have a distinctly different distribution than other sources such ascarbonatites, with less light REE, and higher proportions of the valuable mid-REEand heavy REE. They also often have a Ce deficiency and a smaller Eudeficiency.4 REE grades are low (0.05-0.35 % total RE oxide), but the soils can be minedby relatively inexpensive shallow surface excavations or by in situ recovery.5 In contrast to other types of REE deposits, which commonly require complexand expensive processing, REE in ion-adsorption deposits can be extracted bysimple leaching of common chemicals. The amount recoverable is commonly 60to 90% of the total REE in the soil.


376 U and Th, which are generally associated with REE deposits of other types,are typically very low in the soils of ion-adsorption REE deposits and of this lowU and Th in the soil only a small percentage reports to the leach solution.Mt Pass Bayan Obo Mt Weld Longnan Xunwu10000010000100010010La Ce Pr Nd Sm Eu Gd Tb Dy Ho Er Tm Yb Lu YFigure 11 Chondrite-normalized REE distributions of REE from REE deposits inChina , Australia and USA.

Longnan and Xunwu are important ionadsorptionREE mines in Jiangxi Province, China (grades are poorly known).Mountain Pass is an important bastnäsite mine in carbonatite in California.Bayan Obo REE Mine in China is the largest REE deposit in the World, withdebated origin but probably carbonatite-related ?. Mt Weld is an undevelopedREE deposit derived by secondary enrichment from a carbonatite in Australia.Note steep smooth curves for carbonatite-related deposits, flatter REEdistributions for ionic deposits and Ce and Eu deficiencies.

9 EXPLORATIONReconnaissance samples taken include 9 samples taken in 2010 beforethe Prospecting Licence was granted and another 16 after granting of the licencein early <strong>2011</strong>.(a) Procedures and parametersSamples taken so far (Table 2 and 3) are only of a reconnaissance nature,were taken mainly from convenient roadside exposures and are 1 to 5 kg in size.(b) Sampling methods and sample quality, representativeness, bias.Samples shown in Tables 2 and 3 were scraped mainly from available roadcuts and appear typical of the soils exposed at shallow depths. There isinsufficient data to determine how representative these soils are of thosethroughout the basin. As the leachable REE content is not directly observable inthe field it cannot be said whether they are biased toward higher or lower values.(c) Location, number, type, nature, sample spacing, size of area covered.Locations of the 21 soils and 3 rocks taken are listed in Table 2 and 3 andshown in Figure 12. These are mainly from exposures along logging tracks,spaced from 50 m to 500 m apart over about 2.5 km and mainly in the easternand southern part of the basin.(d) Significant results and interpretation of exploration informationThe most significant result of the analyses from the few samples so faranalyzed (Table 2 to 7) is that some of them contain easily-leachable REE (up to74% recovery from TREE of 620 ppm in one sample). The interpretation of thismeagre information is that it suggests the possibility that Chambe Basin maycontain REE mineralization of the ion adsorption type. The purpose of the currentdrill program is to provide sufficient data to evaluate this possibility.Of interest is MINDECO dike sample 11052306 with 5,495 ppm TREE(Table 5), including 2,131 ppm Y and high levels of other REE, an indication ofthe presence of primary REE enrichment in the rocks of Chambe Basin.


4010 DRILLINGDrilling soils in Chambe Basin using two hand-portable drills was carried outby MINDECO from August to October of <strong>2011</strong> but no details are currentlyavailable, and as no analyses have yet been made there is no new informationon the REE potential.11 SAMPLE PREPARATION, ANALYSES AND SECURITY(a) Sample preparation methods, quality control prior to analyses.The author was not involved in taking the samples listed in Tables 2 and 3,collected in Sept of 2010 and May of <strong>2011</strong>, and has no information on theseaspects for these samples. However, it is thought samples were placed in plasticbags and submitted in this form to the analyzing laboratories.(b) Sample preparation and analysis procedures, laboratory.Samples collected by J. Ishikawa listed in Table 2 were split, pulverized andanalyzed for 14 REE and other elements (Ba, Co, Cr, Cs, Ga, Hf, Mo, Nb, Rb,Sn, Sr, Ta, Th, Tl, U, V, W, Zr) using method ME-MS81 at the North VancouverLaboratory of ALS-Chemex. This method involves fusing the sample to a glasswith Li tetraborate, dissolution in acids and analysis by ICP-MS and is intendedto break down refractory minerals and provide total contents of the elementsanalyzed. The results are listed in Table 4. The ALS-Chemex North Vancouverlab is accredited to ISO-9001 standard. At the laboratory of Nittetsu Mining R &D Centre in Japan splits of the samples were dried at 105˚ C for 24 hours,ground to 2 mm, and 50 g was leached in 500 mg of 2% ammonium sulphate for6 hours. The leach liquor was separated by centrifuge and analyzed by ICP-MS,with the results listed in Table 4.Samples listed in Table 3 collected by MINDECO/JOGMEC and theGeological Survey of <strong>Malawi</strong> were analyzed for REE by ICP-MS at TokyoUniversity. Samples of 15 g were leached in 150 ml solution of ammoniumsulphate.


41(c) Quality control procedures.The author has no information on quality control procedures for sampleslisted in Tables 4 to 7.(d) Opinion on adequacy of sample preparation, security, analyticalprocedures.The author was not involved in the sampling program in Sept of 2010 or inMay of <strong>2011</strong> and has no opinion on sample preparation and security prior toanalyses. Analyses for REE were made by accepted and appropriate methods bymajor laboratories and leaching for loosely-held REE was done by a variant of astandard method (Chi (1988), Chi and Tian (2008)).12 DATA VERIFICATION(a) Data verification by qualified person.A principal purpose of the property visit by the author was to re-collect soilsfrom some sites where samples taken by J. Ishikawa in September 2010 werefound to contain easily-leachable REE (Table 4 and 7). Work done forverification purposes included re-analysis of three samples collected by J.Ishikawa in 2010, analysis of samples re-collected at 4 of the Ishikawa sites andat several other sites, two samples were checked for the identity of the clayminerals, two samples were screened for size distribution, and two soil samplesand one syenite were thin-sectioned and examined by petrographic microscope.Samples were exported on Export Permit EP 02911, issued by theCommissioner for Mines and Minerals of <strong>Malawi</strong> on 23August of <strong>2011</strong>.All analyses were done by ALS Chemex at their North Vancouver laboratory(2103 Dollarton Hwy, North Vancouver, BC, V7H 0A7) except for leachprocedure ME-MS04 which was done at their Perth laboratory (ALS Ammtec, 6Macadam Place, Balcatta, Western Australia, 6021). Both laboratories have ISO9001 accreditation, and also have ISO 17025 accreditation for their mostcommon procedures, but not for ME-MS81, MS-ICP06 or the selective leachesOne syenite rock analyzed for total REE was first crushed with procedureCRU-31 (fine crush below 2 mm) and it and the soils were then pulverized by


42procedure PUL-21 (pulverized to 85% -75 microns). Samples were analyzed fortotal REE and other trace elements by procedure ME-MS81 and for majorelements by method MS-IP06. Samples of 0.2 g sample were fused with 0.9 glithium metaborate at 1,000˚ C, the glass was dissolved in 100 ml 4% HNO 3 /2%HCl and analyzed by ICP-MS for method ME-MS81 and by ICP-AES for methodME-ICP06. The REE results are reported in Table 10.Soil samples were analyzed for leachable REE by ALS-Chemex as follows.Soils were first air dried using procedure DRY-23 and leached by procedure ME-MS23 (a selective leach of weakly bound ions by sodium cyanide with chelatingagents ammonium chloride, citric acid and EDTA, with the leachant buffered atpH 8.5, analysis by ICP-MS) and by procedure ME-MS04 ( a weak leach with 1.0g sample mixed with 25 ml of ammonium acetate solution in acetic acid, shakenfor 2 hours, the leachant separated by centrifuge and decantation, analysis byICP-MS and by ICP-AES). The leached residues from ME-MS04 were alsopulverized (PUL-21) and analyzed for REE by method ME-MS81 and ME-ICP06..Results by method ME-MS04 for the samples listed in Table 8 are shownin Table 10 (total REE) and in Table 11, (leachable REE).1 Resampling and analysis of samples taken by J. Ishikawa On 21 Augustof <strong>2011</strong> the author visited J. Ishikawa in his office at the Geological Survey of<strong>Malawi</strong> in Zomba and was given sub-samples of 3 of his original samples forcheck analyses both of total REE and leachable REE. These results are reportedin Table 9 along with the original analyses of these samples and analyses byMINDECO of the same samples.Samples CHA-4, CHA-6 and CHA-8 have now been analyzed for leachableREE by 3 laboratories and these results are compared in Table 9 and Figure 12.The result of re-analysis of the 3 original Ishikawa samples generally confirmstheir high percentage of leachable REE, from 31 to 74% for all REE or 41 to 86%for all REE except Ce. As previously noted, ionic REE deposits generally show alower percentage of leachable Ce than other REE.It appears that method ME-MS04 gives results similar to the ammoniumsulphate leach used by Nittetsu and University of Tokyo. However, the ME-MS23


<strong>43</strong>leach gives much lower values (see Table 13), is therefore considered unreliableand unsuitable for testing REE deposits of the ionic type and is not discussedfurther.2 Resampling at previously sampled sites. Four of the roadside sitessampled by Ishikawa (CHA-1, CHA-4, CHA-6, CHA-8) were relocated by handheldGPS and resampled at the same depths and from the same scrape as theoriginal samples. As it is conceivable that sampling only of roadside samplesmight bias results, perhaps reducing leachable REE by rain washing orincreasing the leachable REE by evaporation of REE-bearing ground water at thefree surface, at 2 sites (CHA-1, CHA8) samples were taken from new pits dugabout 10 m away from the road cuts. These results are reported in Table 10 and11 and compared with analyses of the original samples in Table 14.Considering that these samples include subsamples of the original samples,others re-collected at the same sites and nearby, and that analyses were done atseveral labs using different methods the agreement is reasonably good. It isconcluded that the results at least demonstrate that some samples contain asubstantial percentage (31 to 74% in Table 14 c) of easily leachable REE.However, the number of samples examined is very small and much more closespacedsampling and repeated reanalysis of a standard sample is needed toseparate analytical uncertainty from natural variability. Work on these aspects willbe part of the MINDECO program.3 Blank and standard. A barren quartz sand sample was submitted as ablank and a sample of REE standard SARF-1 was submitted as a standard.These results are shown in Table 10. Analysis of this standard gave resultswithin 2 std deviations except for La. The blank gave a total of 25 ppm, slightlyhigh, with the larger values for the more abundant REE (Ce, La, Nd, Y).Standards, blanks and duplicates analyzed by ALS Chemex as part of theirquality control gave acceptable results, although the standards used for theleaches generally had much lower concentrations than the samples.

4 Nature of soilsTwo samples (E686956 and E866964) were screened to determine grainsizes, were scanned by X-ray diffraction to determine clay type, and thinsectioned to examine their mineralogy.Figure 13 Example of a roadside-cut sample site. Sample E686958 repeatsIshikawa sample CHA-4, both from the hollowed scrape at 1.5 m depth. Thissample contained 574 ppm TREE, of which 51% was leachable.

58(c) Clay typeTwo soils were thin-sectioned and consist of clay with surprisingly freshk’spar and biotite (Figure 15, 16). These 2 samples were also analyzed for claytype by X-ray diffraction (“XRD”) were reported by J.A. McLeod (MASc, P.Eng) tocontain kaolinite, along with residual silicates from the syenite, as listed below.Sample E686956 (re-sample of CHA-8) contains1. Albite - significant.2. Orthoclase - moderate.3. Kaolinite - minor to moderate.4. Phlogopite(?) - minor.Sample E685964 ( re-sample of CHA-1) contains:1. Kaolinite - significant to abundant.2. Orthoclase - minor.3. Muscovite - minor.4. Quartz - minor.One XRD scan is displayed as Figure 17.5 Parent syenite A sample (E686961) of the central syenite plug (unit SYcof Garson and Walshaw,1969) was taken from an outcrop beside FrancesHut (location Table 8) to determine the mineralogy and total REE content in thisrock, which appears to be the main source of the soils. Major and trace elementsare listed in Table 16, and REE are listed in Table 10. The major elements arefairly typical of syenites, and the trace elements are unexceptional. The 3samples in Table 16 are shown on an alkali vs silica classification plot as Figure18 which shows they have a syenitic composition (intrusive equivalent oftrachyte).

(b) Limitations or failure to verify dataThe soils analyzed for leachable REE are considered a reasonable test of thesmall number of previously reported results from Chambe Basin soils.(c) Opinion on adequacy of verification dataThe amount and composition of easily-leachable REE are the principal mattersthat required verification. However, obtaining a laboratory to provide the mostappropriate method for leaching proved difficult in the short time available. In theopinion of the author better leaching methods should be found before further analysesare done. The author initially attempted to persuade ALS Chemex to carry out exactlythe same procedure used by Nittetsu Mining R & D on the original Ishikawa samples,a simple leach with a 2% ammonium sulphate aqueous solution described by Chi(1988). Unfortunately, ALS declined to carry out this procedure, perhaps partlybecause of pressure of work, partly due to the small number of samples involved, andpartly because they would first have to develop quality control procedures andleachable-REE standard samples. Other commercial laboratories would likely have asimilar response and, while it may have been possible to persuade a university orother laboratory to carry out these leaches these likely lack accreditation or even thesort of quality assurance provided by commercial labs and required for <strong>43</strong>-<strong>101</strong> reports.Because the ammonium sulphate leach noted above was not available twodifferent leach procedures (see Item 11 (b)) offered by ALS Chemex were chosen asalternatives, both very weak leaches that selectively strip loosely bound ions. Theleach method ME-MS04 (ammonium acetate) gave results comparable to theammonium sulphate leaches at the Nittetsu and Mitsui laboratories, but method ME-MS23 (ammonium chloride) appears to extract much lower percentages of REE(Table 13).Summary From the author’s brief August visit the following were verified.1 Chambe basin is a large bowl in a subcircular syenite intrusion that contains thicksoils. The soils appear to be derived from the underlying syenite, which crops out inmany places and also occurs as residual boulders in the soils.2 Soils consist of fragments of feldspar and ferromagnesian minerals frombreakdown of the syenite, mixed with kaolinite from weathering of the rock. Soil


65profiles have well developed lower grey-white C layers, brown B layers, and thindark-grey organic A layers, although only shallow sections were seen. Analysessuggest the soils generally have 2 to 3 times the REE values of the parent syenite.3 Samples collected by J. Ishikawa were re-analyzed and the results of total REEand leachable REE found to be generally consistent with the previous analyses.4 Sample sites reported by J Ishikawa were re-located within a metre or two of thepositions he reported, four were resampled and analyzed, and 2 of them repeated alsofrom fresh pits dug nearby. Results from these samples are broadly consistent withthe previously reported total and leachable REE results at these locations. EightIshikawa samples contained 234 to 739 ppm TREE, MINDECO (13 samples) 194-642ppm TREE, this report (11 samples) 401-745 ppm TREE. Th and U contents of allsoils are low, with Th from 1 to 29 ppm and U from


6613 MINERAL PROCESSING AND METALLURGICAL TESTINGNo mineral processing or metallurgical studies have been made. However, theonly feasible method of processing this type of deposit is by chemical leaching. In Item8 it was noted that one of the attractions of the ion-adsorption REE type of deposit istheir metallurgical simplicity relative to the often-complex processing required for othertypes of REE deposit. Analyses of REE leached from exploration samples, by dilutesolutions of ammonium salts for example, should be a good initial indication of theirextractability with such solutions on a commercial scale. However, these analyses areno substitute for metallurgical tests.14 MINERAL RESOURCE ESTIMATESThe scattered meagre data do not allow any estimate of a REE mineralresource in the Chambe Basin.15 MINERAL RESERVE ESTIMATESThe data are not yet available to estimate a REE mineral resource in theChambe Basin.16 MI<strong>NI</strong>NG METHODSNo consideration of mining methods has been made at the present time.However, the potential material is surficial soil and is known to be shallow, extendingfrom surface down to about 15 m depth. Presumably, shallow surface mining and insitu recovery will be considered if the project obtains encouraging results.17 RECOVERY METHODSAt this preliminary stage of exploration no specific information on any recoverymethod is appropriate, but would likely involve ion exchange of loosely-held REE bydilute aqueous solutions.18 PROJECT INFRASTUCTURENo consideration has yet been given to project infrastructure. However, in Item5 (c) the necessity of rehabilitating the existing cableway, or some other means of


67transporting material and people to and from the basin should the project proveencouraging was noted.19 MARKET STUDIES AND CONTRACTSMarket studies or contracts for possible mineral products have not been made.20 ENVIRONMENTAL STUDIES, PERMITTING AND SOCIAL OR COMMU<strong>NI</strong>TYIMPACTNo environmental studies have yet been made but Initial environmental studies(see Item 27) are part of the current phase of exploration.Permitting is not required for the current activities and possible future permitrequirements have already been commented on in Item 4 (g).The present phase of exploration has a significant beneficial community impact.It provides work and training (Anonymous (<strong>2011</strong>b) for at least 25 citizens of <strong>Malawi</strong>including geologists, drillers, porters, samplers, and drivers, many from nearby villagessuch as Nakoya. As required by the terms of the licence, labour and supplies areobtained within <strong>Malawi</strong> to the extent possible.21 CAPITAL AND OPERATING COSTSNo estimation of capital and operating costs has been made or is appropriate atthe present preliminary stage of exploration.22 ECONOMIC ANALYSISAt this early stage there is insufficient data to carry out an economic analysisand none has been made.23 ADJACENT PROPERTIESAlthough a number of REE deposits are known in <strong>Malawi</strong>, some of which arebeing evaluated economically, none are of the ion-adsorption REE type and thereforecannot usefully be compared with the Chambe Basin.


6824 OTHER RELEVANT DATA AND INFORMATIONTo the author’s knowledge, there is no additional information or explanationnecessary to make this report understandable and not misleading.25 INTERPRETATION AND CONCLUSIONSDespite current interest in exploration for REE deposits, few deposits of theion-adsorption type are known outside China, where they are a significant source ofREE, especially of the mid and heavy REE, and they appear to have someadvantages over other types of REE deposit. Although only a small amount ofinformation is yet available, some soil samples of the Chambe Basin have highpercentages of leachable REE and suggest it may have potential for a REE deposit ofthe ion adsorption type, as originally suggested by J. Ishikawa, JOGMEC andMINDECO. The Chambe Basin deserves a thorough sampling to determine the size,grade, recovery, and economic potential of leachable REE.27 RECOMMENDATIONSThe program briefly described below to explore for a REE deposit of the ionadsorption type was prepared by MINDECO and, as the work and the expenditureshave both been presented to and approved as commitments by the Government of<strong>Malawi</strong> in the course of applying for the licence, the author has no opportunity torecommend anything different. However, in the author’s opinion the MINDECOprogram is well designed, systematic, and should provide the data to make an initialevaluation of the leachable REE mineralization in the Chambe Basin. The author hasno hesitation in endorsing this program.Field work on the exploration program, being conducted by MINDECO underdirection of H. Harada, began in August of <strong>2011</strong>. Estimated expenditures are listed inTable 18 and the principal activities of this program are as follows (Anonymous,<strong>2011</strong>b).Geology Drilling of about 160 shallow drill holes in soils on a 200 m grid (Figure 23)using two portable drills. Holes will be logged lithologically and radiometrically, andspecific gravity of soils measured. Samples will be taken every metre or at lithological


69boundaries. Pits and trenches will be excavated to examine the nature of the soilprofile. Surface geology will be mapped in Chambe Basin and a geological traversemade on the bauxite of the nearby Lichenya Plateau to the east.Analyses About 1,650 samples will be analyzed for 27 elements by ICP-MS andleaching tests made on about 500 samples using dilute ammonium sulphate solution.Selected samples will be examined petrographically and by X-Ray diffraction..Environmental. Flow of streams will be monitored, their pH and electricalconductivity measured and water samples taken. Growth of plants in leach residueswill be tested.Table 18 Expenditures estimated by MINDECO for the first phase ofexploration in Chambe Basin.Cost centre US $Preliminary visits and presentations $ 98,393Wages , including overheads $ 362,199Personnel travel expenses $ 97,181Equipment and supplies, transport to site $ 175,346Laboratory analyses, tests $ 222,793Spring Stone Ltd office costs $ 75,000Local contractor costs $ 68,053Accommodation, food, sample shipping,fuel $ 9,927Total $ 1,108,892If results in this initial exploration are encouraging then further phases ofexploration will be carried out, and will likely include closer-spaced drilling, pitting,metallurgical tests, consideration of mining and REE recovery methods and costs,improvement to access, evaluation of environmental issues, and market studies.Accurate analyses of total REE appear to be readily obtained from severallaboratories, including ALS-Chemex. However, although the leachable REE analysesby ALS Chemex method ME-MS04 appear to be compatible with analyses by Nittetsuand Mitsui labs it is suggested the amount of soil analyzed is too small and should be


70increased from 1 gram to at least 50 grams. If possible, a laboratory willing to carry outthe simpler ammonium sulphate leach should be found and appropriate testing ofleach performance done. No standard sample for leached REE is available and it isrecommended that a leach standard sample be made from soil on the Property,perhaps from site CHA-4, which gave high recovery (74%) of leachable REE from asample with relatively high TREE (~620 ppm) and is easily accessed at the roadside.Figure 23.
