Systematic mapping and channel sampling of outcropping massive sulphide mineralisation by Asiamet Resources have shown the potential for a standalone polymetallic deposit at the BKZ prospect in Central Kalimantan, Indonesia.
BKZ is 800 metres north of Asiamet’s core BKM Copper Project where bankable feasibility studies are well advanced.
A continuous 15-metre rock channel sample collected in the southern part of the BKZ prospect averaged 19.5% zinc, 8.1% lead, 121 g/t silver, 0.69 g/t gold and 0.50% copper.
Individual one-metre rock channel samples collected from three separate locations over the mineralised strike extent outlined to date returned up to: 24.2% zinc, 14.4% lead, 0.83% copper, 86 g/t silver and 0.24 g/t gold; 17.7% zinc, 16.6% lead, 0.23% copper, 174 g/t silver and 1.34 g/t gold; and 7.6% zinc, 6.1% lead, 0.10% copper, 246 g/t silver and 0.36 g/t gold.
Asiamet says there is excellent potential to identify additional polymetallic mineralisation along strike associated with a well-defined coincident zinc-lead -copper in soil anomaly measuring 400 x 200 metres.
Drill holes and surface sampling of massive sulphide-bearing outcrops confirm mineralisation is near surface and has at least 150 metres of strike extent.
The company says additional high-grade polymetallic mineralisation was also mapped and sampled to the immediate south of BKM copper deposit with rock chips assaying to 35.6% zinc, 26.2% lead, 2.94% copper, 1.0 g/t gold and 3440 g/t silver. The location and style of this mineralisation is similar to that identified at BKZ and represents a second-high priority polymetallic target that warrants drill testing.
A total of 53 rock chip channel samples were collected in the vicinity of an historical drill hole which intersected 16 metres @ 5.75% zinc, 2.78% lead, 0.16% copper, 0.64g /t gold and 57.5 g/t silver from 6 metres.
Channel samples were taken within a mapped area measuring 300 x 300 metres and the discovery of new massive sulphide-bearing outcrops confirms a strike length of at least 150 metres.
Asiamet’s CEO Peter Bird said, “Potential for polymetallic mineralisation in the BK district has been known for some time, however the grades and thicknesses indicated by this most recent work together with the identification of a second area of similar potential close to the advanced BKM project are very exciting.
“While Asiamet will continue to focus its effort on progressing development of the BKM Copper Project and nearby copper prospects, it is also important to appreciate the exceptional potential for additional discoveries on the KSK property. Asiamet looks forward to further advancing these high grade polymetallic prospects in the near future.”
