Asiamet's Exceptional Zn-Pb-Ag-Au Drill Results Upgrade Potential of BKZ Discovery
| ||Asiamet Resources Limited ("ARS" or the "Company") is pleased to announce that scout drilling at the BKZ prospect continues to intersect broad zones of near surface high grade base and precious metal rich mineralisation. Results received for step-out drilling along strike of earlier intersections (refer ARS Press Releases October 3, 2017) have exceeded all expectations and provide added confidence that the Company has potentially discovered a stand-alone high grade polymetallic Zn-Pb-Ag-Au deposit on its Kalimantan Surya Kencana ("KSK") 6th Generation Contract of Work ("CoW"), in Central Kalimantan, Indonesia. |
BKZ is located approximately 800m north and proximal to the main access road leading to the Company's feasibility stage BKM Copper Project. The discovery of thick, very shallow, high grade polymetallic mineralisation close to planned and propose infrastructure has the potential to transform the value of the KSK property and is considered to be a very significant development for the project and Company.
To date, seven holes (705m metres in total) have been drilled to test a zone of massive sulphide outcrops over an area of 150m x 100m. Highlights of the latest batch of drill results received include:
||30.0m at 8.9% Zinc, 2.2% Lead, 46g/t Silver and 0.37g/t Gold (from 43 metres)
|Including9.0m at 12.0% Zinc, 5.4% Lead, 94g/t Silver, 0.56g/t Gold (from 44 metres)
|Including9.0m at 12.6% Zinc, 1.2% Lead, 28g/t Silver, 0.15g/t Gold (from 61 metres)
The first hole on section line BKZ33650 was drilled 50m south of BKZ33700-02 (113.9m End of Hole "EOH"), which intersected 39m at 7.3% zinc, 2.3% lead, 33g/t silver and 0.33g/t gold from 41 metres (refer ARS Press Releases October 3, 2017). BKZ33650-01 (113m EOH) intersected a broad zone of quartz-sulphide mineralisation from 43m depth, which outcrops approximately 50m to the east. The mineralisation comprises quartz-sulphide veins to massive sphalerite (zinc), galena (lead), chalcopyrite (copper) and pyrite (Figure 2). This intersection is consistent with the interpreted geometry of BKZ mineralisation observed in adjacent holes, indicating the quartz-sulphide body is approximately 40-50 metres in true thickness.
The results of BKZ33650-01 confirming high grade zinc-rich polymetallic mineralisation extends to the south of previous drilling is very promising. This is the highest-grade broad interval of zinc-rich mineralisation the Company has drilled to date and provides further evidence that polymetallic mineralisation is increasing in grade to the east. It also enhances our understanding of the structural and stratigraphic controls on the BKZ mineralisation which remains open laterally and to depth. Step-out drilling continues to the south and east and the drill rig is currently positioned on BKZ33650-02, testing the eastern extensions to the high-grade polymetallic mineralisation intersected in BKZ33650-01.
A drill hole location plan and a table of full assay results are provided in Figure 1 and Table 1 respectively.
Peter Bird, Asiamet's Chief Executive Officer commented:
"As the BKM Copper Project is being advanced through Feasibility Study, a pipeline of additional prospects on the KSK COW such as BKZ Polymetallic, Beruang Kanan West, Beruang Kanan South and Baroi represent high potential walk up drill targets of which some are to be progressively tested over the coming weeks and months. The Company views the recent results from drilling at BKZ, the first pipeline target to be tested in the current program, as a clear illustration of the substantial upside potential remaining on the very underexplored KSK COW. Work undertaken by the Company and its predecessor partners to date suggests that the greater BK area represents a polymetallic mineral district covering approximately 10-15 square kilometres, the potential of which is only beginning to see daylight. The discovery and delineation of the BKM copper deposit in the past three years and these recent exceptional grade polymetallic results from early drilling at BKZ highlight the potential to multiply the value of the KSK COW through systematic exploration. the Company is very excited by this opportunity and looks forward to unlocking this value for its stakeholders."

Table 1: Recent drill intercepts.
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.

intercept is described by the entire thickness and the
average grade of mineralisation.
