Drilling confirms Copper Bore extension
The Copper Bore Project of Southern Cross Goldfields is in Western Australia’s Mid West region.
ASSAY results from recent step-out drilling have confirmed a significant
down-plunge extension of the recently discovered Southern
Gossan prospect, which is part of Southern Cross Goldfields’ Copper
Bore Project in Western Australia. Additional step-out drilling and
geophysics are now being carried out to test for further extensions to
the mineralized horizon.
One step-out diamond drill hole returned an intersection of 2.6 metres
from 265.4 metres down-hole @ 3.0% copper, 0.9 grams/tonne gold,
4.2% zinc, 19.2 grams/tonne silver and 0.2% lead within a broader intersection
of 4.0 metres from 265 metres @ 2.2% copper, 0.7
grams/tonne gold, 3.1% zinc, 14.3 grams/tonne silver and 0.2% lead.
It was the second step-out hole to be drilled at Southern Gossan
and tested the mineralized horizon 60 metres to the south and 80
metres down-dip of an earlier hole which intersected 5 metres @
2.0% copper, 1.9 grams/tonne gold, 7.1% zinc, 25.4 grams/tonne
silver and 0.4% lead.
VMS mineralization at Southern Gossan has now been defined over
a strike length of about 150 metres and to a vertical depth of 230 metres
and remains open down-plunge and along strike to the north and
south. The latest intersection, including its higher copper grade than
previous results, is viewed as highly encouraging by Southern Cross’
geological team, providing further significant evidence for an emerging
VMS discovery at Southern Gossan.
The Copper Bore project area is 400km north-east of Perth with the
Southern Gossan prospect at the southern end of a 10km-long
prospective VMS horizon. Base metals mineralization has now been
confirmed at multiple locations along this prospective horizon.
The company is extremely encouraged by the results received to date
from the Copper Bore Project and intends to progress exploration activities
at this project as a priority in parallel with its ongoing gold exploration
and development activities. The Copper Bore activities include
further step-out drilling, down-hole electromagnetic surveying to identify
off-hole conductors representing accumulations of massive sulphide
mineralization, surface EM across the remaining 10km strike of the host
horizon and particularly across two aeromagnetic bullseye anomalies,
and new detailed aeromagnetic surveys.
Bashkol reconnaissance exceeds expectations
RESULTS of reconnaissance work by Kentor Gold over the Bashkol
exploration licence area in the far east of the Kyrgyz Republic have exceeded
the company’s expectations. Kentor can now confidently plan
a geological and geophysical program that should lead to identification
of drill targets.A program of geological traverses, chip sampling
and one channel sample was completed to assess the overall potential
of the area following encouraging results at Bekbulaktor
prospect. The primary focus was a belt of mineralized granite stretching
15km from Bekbulaktor to Sharkatma. Kentor geologists sampled
the latter in 2008 and recorded gold assays of up to 12 grams/tonne
from channel sampling.
The most encouraging result from the 2011 reconnaissance program
was a continuous channel sample of 14 metres @ 5.74 grams/tonne
gold, 1.03% copper and 97 grams/tonne silver in the valley of the Molo
Stream. There was also widespread presence of gold and copper in mineralized
granite in numerous locations over the 15km.
The Molo and Sharkatma areas are at altitudes ranging from 3000
to 4000 metres on the north side of Kuyliu Stream in the Teskey Ala-
Too Range of the eastern Kyrgyz Tien Shan Mountains. The Bashkol
area is accessible from a major road used for access to the Saryjaz
Valley and the Inylchek tin deposits. A minor road runs along Kuyliu
Valley and provides vehicle access to the Molo and Sharkatma areas.
Kentor is also planning an exploration drilling program at Bekbulaktor
prospect this year after channel sampling over a large area returned
high-grade gold and copper results. A program of bedrock
channel sampling, geophysics and soil sampling was undertaken to
gain a deeper understanding of the potential of a large zone of mineralized
granite studied in the 2009 and 2010 field seasons.
The program established the presence of widespread gold and copper
mineralization over an area 2km-long and 1km-wide. A best result
of 12 metres @ 14.07 grams/tonne gold and 1.83% copper was returned.
Other results included 13 metres @ 4.90 grams/tonne gold,
8 metres @ 5.65 grams/tonne gold and 0.6% copper, 10 metres @
2.53 grams/tonne gold, and 11.5 metres @ 2.83 grams/tonne gold.
