Zheng Guang Mineralisation Extended
Leyshon Resources Limited ("Leyshon") (ASX & AIM: LRL) today reports that
results from a major drill programme have extended mineralisation at the Zheng
Guang gold-zinc-silver project in Heilongjiang, northeast China.
Results from the first six diamond drill holes have extended the 1.2 million
ounce equivalent high grade gold-zinc Main Ore Zone. In addition near surface
oxide mineralisation has been discovered in an area of no outcrop.
Significant assays include ZGD104 (10 metres at 3.52 g/t Au) and ZGD107 (8
metres at 2.7 g/t Au). Core logging of the recently drilled holes ZGD 118, 122
and 126 indicates that the Main Ore Zone mineralisation increases significantly
in thickness to the north and west.
ZGD103 has confirmed wide zones of stacked mineralisation totalling 29 metres in
a 63 metre intersection including (9 metres at 5.22 g/t Au). ZGD 105 has
reported (5 metres at 7.32 g/t Au) and has confirmed previously high grade
intersections in a zone containing a significant percentage of the Main Ore Zone
resource estimate.
The programme is progressing well with 19 holes drilled to date totalling nearly
8,200 metres. A high performance reverse circulation rig is due to arrive next
week to test the economically significant oxide zones bringing the compliment to
four diamond drills, two reverse circulation drills and 110 field personnel.
This year's programme is the largest to be undertaken in Heilongjiang in recent
years and is expected to increase the recently reported initial inferred
recoverable resource estimate of 930,000 ounces gold, 64,000 tonnes zinc and 2.6
million ounces silver.
Discovered in 2000 Zheng Guang has been interpreted as an epithermal carbonate
gold-base metal deposit related to the Duobaoshan porphyry copper deposit eight
kilometres to the north.
Managing Director Paul Atherley commented: "The Main Ore Zone has already been
extended on the first six holes and is open to the north west. We are now
increasingly confident that the Zheng Guang resource estimate will increase
significantly by the end of the programme."
Leyshon has firmly established its presence in China over the past two years and
is pioneering the opening up of the mineral rich province of Heilongjiang to
modern exploration techniques and foreign investment.
The Company has recently entered into a 20 year joint venture agreement with the
Qiqihar Brigade for the financing development and mining of Zheng Guang. Leyshon
remains one of the very few foreign resource companies with its main operating
office in Beijing.
