Asiamet Resources Limited (LON:ARS, CVE:ARS) described as 'very exciting' the discovery of a second potentially high grade polymetallic prospect at its BKZ prospect in Kalimantan, Indonesia.
It came as the group reported on work done in April at BKZ, which lies around 800metres north of the group's main BKM copper project, where bankable feasibility studies are ongoing.

Results from BKZ showed high grades and excellent potential to expand the resource.
Highlights from sampling, which included one metre channel samples collected at three locations, were one length which returned 24.2% zinc, 14.4% lead, 0.83% copper, 86g/t silver and 0.24g/t gold.
Another sample hosted 7.6% zinc, 6.1% lead, 0.10% copper, 246g/t silver and 0.36g/t gold.
Significantly, further high grade mineralisation was also mapped and sampled to the immediate south of the BKM copper deposit.
Here, a rock chip sample assayed 35.6% zinc, 26.2% lead, 2.94% copper, 1.0g/t cold and 3440g/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," Asiamet said.
Asiamet's chief executive 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 for investors 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."
Broker SP Angel said: "The discovery of high grade polymetallic mineralisation close to the BKM project area underlines the wider potential of Asiamet’s licences in central Kalimantan, however, the company recognises the importance of continuing to progress the feasibility study and the probable subsequent development of BKM as its top priority."
