Asiamet Resources (ARS) is making strong progress on its limestone resource drilling programme at the Rinjen prospect, approximately 12 kilometres north of Asiamet's flagship BKM copper heap leach project in Central Kalimantan, Indonesia.
The limestone drilling programme is now 50% complete, with all holes intersecting limestone at target depth.
Six holes of the 12-hole programme have been finished in the initial resource area.
Early assays confirm very high-quality limestone, with purity running at +95%.
The work enables Asiamet to secure locally-sourced limestone that is a critical enabler for BKM, avoiding significant import costs and underpinning a low operating cost base
Based on current progress, the programme is expected to complete by mid-October.
"The KSK operational team is executing our limestone resource definition programme to plan, and we are pleased with the results to date showing continuation of the limestone from surface outcrop to depth and extending the dimensions of the deposit,” said Darryn McClelland, chief executive of Asiamet.
“The high quality of the limestone is especially pleasing as this typically translates into lower consumption of limestone in processing.”

This limestone drilling work forms part of a wider package of optimisation initiatives, including soluble copper recovery improvement and a revised power solution, both of which will also be reported on soon. The results will all be incorporated into the BKM economic model, supporting the ongoing strategic investor process. This, says McClelland, “is progressing to plan."
