Limestone Resource Drilling Commences at BKM Copper Project

Asiamet Resources Limited (AIM: ARS) is pleased to announce the commencement of limestone resource drilling at the Rinjen prospect, approximately 12km north of Asiamet's flagship BKM Copper heap leach project in Central Kalimantan, Indonesia.

Securing a local limestone source for use in BKM's process plant neutralisation circuit is a key enabler of the project's low operating cost base, eliminating the need to import lime from elsewhere in Indonesia at significantly higher cost.  

The limestone resource drilling programme is being executed by the Kalimantan Surya Kencana ("KSK") operations team, which has previously completed significant drill campaigns in the area. The first phase comprises approximately 600-700 metres of drilling in one location. A second location is currently being assessed as part of a planned second phase aimed at defining additional limestone resource.

Darryn McClelland, CEO of Asiamet, commented:

"It is pleasing to recommence on-ground activity in support of the BKM project with the limestone resource definition programme a key step in delivering a low-cost operation. Our KSK operational team has done an excellent job establishing the improved access road, temporary support facilities, access paths and drill pads to support the drilling programme.

The first drill hole testing for undercover extensions to a substantial limestone outcrop is now complete having intersected good thicknesses of limestone as predicted.

Given the very significant operating cost benefit of sourcing limestone locally within the Company's KSK Contract of Work, verifying the extensive surface assessment work completed over the last 12 months is particularly satisfying.

Executing this programme and the appointment of the BKM Project Director represent important milestones as we advance financing of the BKM Project. I look forward to providing further updates as the momentum to deliver BKM continues to build."
