MAPPING and channel sampling of outcropping massive sulphide mineralisation have shown the potential for a standalone polymetallic deposit at Asiamet Resources BKZ prospect in Central Kalimantan. BKZ is 800 metres north of the company’s BKM Copper Project, where bankable feasibility studies are well advanced.

A continuous 15-metre rock channel sample collected in the southern part of BKZ averaged 19.5% zinc, 8.1% lead, 121 g/t silver, 0.69 g/t gold and 0.50% copper.
One-metre rock channel samples collected from three separate locations over the mineralised strike extent returned 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.
Additional high-grade polymetallic mineralisation was also mapped and sampled to the south of BKM, 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 style of mineralisation is similar to BKZ and represents a second-high priority polymetallic target that warrants drill testing.
The company has also received the final batch of assays for resource infill and expansion drilling at BKM. The results continue to impress, with near-surface high-grade copper assays returned from the BK058 Zone confirming excellent internal continuity.
Results have been incorporated into the ongoing BKM feasibility study to refine and potentially improve the project’s already favourable economics. Hackman & Associates are incorporating all 2016/17 drill results into an updated resource estimate.
The diamond drilling program comprised 122 holes for 12,480.9 metres with the final five holes drilled in the southern part of the BKM deposit.
Better results are: 58 metres from 6.5 metres @ 1.45% copper, including 20.5 metres from 7.5 metres @ 2.24% and 18.5 metres from 36 metres @ 1.71%; 17.5 metres from 25.5 metres @ 1.57%, including 9.5 metres from 27.3 metres @ 2.37% and 4.5 metres from 31.5 metres @ 4.15%; and 4 metres from 46.5 metres @ 3.15%.
Asiamet’s CEO Peter Bird said, “Asiamet is very excited by the opportunity to begin testing some of these high potential targets in the second half of 2017.”
