Follow up scout drilling by Asiamet Resources at the BKZ prospect in Central Kalimantan, Indonesia, has intersected further near-surface high-grade base and precious metal rich mineralisation along strike of earlier hits. The results provide confidence that BKZ may be a standalone polymetallic deposit, although further drilling is required to determine the ultimate dimensions and continuity of the mineralised body.
BKZ is about 800 metres north of Asiamet’s feasibility stage BKM Copper Project and both are within the KSK Contract of Work (COW) area. Being the most accessible, BKZ is the first of multiple targets outside BKM being tested in the wider BK district.
To date, six holes, for 592.7metres, that have been drilled to test a zone of massive sulphide outcrops over an area of 150 x 100 metres have intersected polymetallic mineralisation, however assay results are only yet available for two holes.
Highlights are: 3.2 metres from 1.8 metres @ 1.15 g/t gold and 67.8 g/t silver, and 7.0 metres from 5.0 metres @ 3.7% zinc, 1.3% lead, 46 g/t silver, 0.24 g/t gold and 1.0% copper in one hole; and 39 metres from 41 metres in the other hole @ 7.3% zinc, 2.3% lead, 33 g/t silver and 0.33 g/t gold, including 23 metres from 41 metres @ 11.1% zinc, 3.8% lead, 50 g/t silver and 0.42 g/t gold.
The BKZ scout drilling program is focused on expanding the zinc-lead-silver-gold mineralisation intersected in three historical drill holes.
The mineralisation remains open in all directions and at depth, and drilling to date indicates the mineralisation is increasing in grade to the east.
The focus of the ongoing program is to expand the massive and semi-massive sulphides by completing step-out drilling to the north, south and east.
Asiamet’s CEO Peter Bird said, “Asiamet is extremely pleased with the initial follow up drill results from our BKZ prospect, the first of multiple targets to be drilled in the BK district over the coming months. The base and precious metals grades received to date are exceptional and of a similar tenor to those reported at some of the highest quality base metals mines globally.
“While a substantial amount of further drilling is required to ultimately determine the dimensions and continuity of the mineralisation, we are now more confident of BKZ developing into a stand-alone deposit discovery with the potential to share infrastructure with any proposed mine development at BKM.
“We have consistently stated our belief that the potential of the KSK COW is vastly greater than BKM alone and these early results re-enforce that view. Our ongoing drill programs will continue to target additional copper resources to further strengthen the BKM project and to test the numerous polymetallic targets evident in our surface exploration data.”
