Three holes at BKZ, located in Central Kalimantan, have intersected high grade copper mineralisation, confirming a strike length of at least 110m and a true thickness of up to 50m.
The company said multiple intersections of high grade copper-silver mineralisation within a primary feeder structure at BKZ is “very significant” with up to 11.8% copper and 415 grammes per tonne silver reported over 1m sample intervals. Further drilling is required to determine its dimensions, Asiamet said.
The BKZ exploration programme includes a total of 14 holes for 1,354 metres of diamond core drilling.
The drill rig is currently at the Beruang Kanan West (BKW) prospect, testing several coincident copper in soil, rock and chargeability anomalies. Following completion at BKW, the drill rig will move back to BKZ.
“The discovery of a copper feeder zone at BKZ with potential for considerable strike and depth extent has some exciting implications for the wider project and we are looking forward to reporting further exploration results over the coming weeks and months while the BKM feasibility study is being completed,” said chief executive Peter Bird.
Exploratory drilling will continue to test the strike, width and downdip continuity of the interpreted feeder structure in the southern part of BKZ.
Bird said ongoing exploration in the BK district continues to make progress with success in discovering new mineralisation and advancing drill targeting.
“Since recommencing exploration two months ago our strike rate has been exceptional,” he added in the statement.
“A major north-south basement structure has been identified which controls a district scale polymetallic mineral system and within which we have already defined a very significant copper deposit at BKM.”
