Asiamet Drilling Expands High Grade Zinc Rich Polymetallic Mineralisation at BKZ
October 3, 2017 / JMN Wire / Asiamet Resources Limited ("ARS" or the "Company") is pleased to announce that follow up scout drilling at the BKZ prospect has intersected further near surface high grade base and precious metal rich mineralisation along strike of earlier hits (refer ARS Press Release February 23, 2017). While further drilling is still required to determine the ultimate dimensions and continuity of the mineralised body, these latest results are highly significant and provide confidence for a potential stand-alone high grade polymetallic deposit.
BKZ is located approximately 800m north of the Company"s feasibility stage BKM Copper Project in Central Kalimantan, Indonesia. Being the most easily accessible, BKZ is the first of multiple targets outside BKM currently being tested in the wider BK district. To date, six holes (592.7metres) that have been drilled to test a zone of massive sulphide outcrops over an area of 150m x 100m have intersected polymetallic mineralisation, however assay results are only yet available for two holes. Further results will be reported as assays are received.
Highlights of the results received to date include:
- BKZ33700-01
- 3.2m at 1.15g/t Gold and 67.8g/t Silver (from 1.8 metres)
- 7.0m at 3.7% Zinc, 1.3% Lead, 46g/t Silver, 0.24g/t Gold,1.0% Copper (from 5.0 metres)
- BKZ33700-02
- 39m at 7.3% zinc, 2.3% lead, 33g/t silver and 0.33g/t gold (from 41 metres)
- Incl. 23m 11.1% zinc, 3.8% lead, 50g/t silver and 0.42g/t gold (from 41 metres)
The current BKZ scout drilling program is focused on expanding the Zinc-Lead-Silver-Gold mineralisation intersected in historical drill holes (BKZ-1, BKZ-2, BKZ-3), where BKZ-1 (123.1m End of Hole "EOH") reported 9.47% Zn, 4.87% Pb, 0.26% Cu, 96.5g/t Ag and 0.56g/t Au over 8 metres from 6.0 metres (refer ARS Press Releases February 23, 2017).
The first hole, BKZ33700-01 (92.2m EOH), was drilled 45m northwest of BKZ-1 and intersected oxide gold mineralisation from top of hole to 5 metres depth, followed by strong polymetallic sulphide mineralisation to 12m depth. The host rock is a polymict breccia cut by cm-scale quartz -- sulphide veins. This hole was drilled on the western margin of the known mineralisation, and drilled through the mineralised zone at approximately 15m depth into a sequence of unmineralised volcanic rocks.
The second hole BKZ33700-02 (113.9m EOH) was drilled 63m northeast of BKZ-1 and 75m east of BKZ33700-01. This hole intersected a broad zone of quartz-sulphide mineralisation over a downhole interval of approximately 40 metres from 41m depth. The polymetallic mineralisation intersected in this hole confirms the geometry of the mineralisation seen in the adjacent historical holes BKZ-1, 2 and 3, of a quartz-sulphide body approximately 40-50 metres in true thickness. This broad intersection of polymetallic mineralisation comprises quartz-sulphide veins to massive sphalerite (zinc), galena (lead), chalcopyrite (copper) and pyrite (Figure 2), within an interpreted low-angle thrust fault.
The strong results received to date indicate that the high-grade zinc-lead-silver-gold-copper mineralised system at BKZ has excellent potential to develop into a stand-alone deposit located less than 800m north of the Company"s feasibility stage BKM Copper Project. 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 drill program is to expand the massive and semi-massive sulphides by completing step-out drilling to the north, south and east. There is currently one rig active, positioned on BKM33700-04 and testing the eastern extensions to the high-grade polymetallic mineralisation intersected in BKM33700-02.

Notes: Grade intercepts are calculated as a weighted average grade ≥1.0% Zinc (uncut). True widths are interpreted to be between 80-100% of the reported lengths, unless otherwise stated. Orientation of the mineralised domain is estimated to have an azimuth of 340 degrees and a dip of -25 degrees to the northeast.

Peter Bird, Asiamet"s Chief Executive Officer commented:
"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, all of which we anticipate will unlock very significant value for our stakeholders. We look forward to reporting further results from this exciting phase of our work as they come to hand."
