The Zheng Guang gold project lies approximately 8 kilometres south-east of Duobaoshan and was discovered by the HLJBGMR in 2000 through a regional stream sediment sampling programme. Follow-up work during 2002 included detailed soil sampling, diamond drilling, trenching, shafts and adits, defining strong mineralisation at the Zheng Guang prospect and outlining geochemical anomalism and other zones of mineralisation over a strike length of 2 kilometres. As well as testing the shallow potential of the deposit, the HLJ-BGMR also completed deep vertical drilling, confirming the depth extent of the mineralisation to over 350 metres in the southern section of the deposit.
All available data has been captured, compiled and interpreted and an exploration
programme designed to define the size and key controls on mineralisation. The initial
programme consists of approximately thirty diamond drill holes for 4,500 metres
testing the deposit at 100 metre section spacings to a vertical depth of approximately
150 metres.
Results from the first six drill holes have been received and are encouraging, with
strong intercepts (including 16 metres @ 6.09 g/t from 69 metres in hole ZGD006
and 44 metres @ 3.16 g/t Au from 50 metres) being recorded from the central
section of known mineralisation.
Broad zones of mineralisation (up to 44 metres down hole) are present and that
encouraging widths of higher-grade material are still open at depth, to the west.
High grade pyrite/galena veins grading up to 60 g/t Au have been intersected
within the broader, lower-grade envelopes although their orientation and continuity
is as yet unknown.
Drilling was completed in September 2004 and has tested over 700 metres of
potential strike and the down-dip potential of the mineralisation. Follow-up drilling,
particularly to test the stronger intercepts at depth, will also be completed prior to
the completion of the 2004 programme. |
