Battery Mineral Resources Corp. announced a robust NI 43-101 resource update for its Punitaqui copper mining complex in Region IV of Chile. This resource estimate, completed for Battery by independent consultants JDS Energy & Mining Inc. ("JDS"), is a major milestone for the company.

The resource estimate is based on Phase 1 drill program, initiated in August 2021 which totalled 32,526 meters ("m") of diamond core drilling and also includes the drilling and mining data from the Cinabrio mine completed by prior operators including Glencore PLC. The BMR Phase 1 drilling focused on three zones at Punitaqui: Dalmacia, San Andres, and Cinabrio Norte. An updated technical report will be filed on the Company's website and SEDAR within 45 calendar days of this disclosure.

This Punitaqui resource update is separated into four underground resource zones: Dalmacia, San Andres, Cinabrio Norte and Cinabrio. Total sulphide indicated resources are 6.2M tonnes grading 1.14% Cu and 2.47 g/t Ag. Total sulphide inferred resources are 3.1M tonnes grading 0.93% Cu and 2.64 g/t Ag.

At the Cinabrio mine, the remanent pillars contain sulphide indicated resources of 1.0M tonnes at 1.51% Cu which could be mined in conjunction with the use of mine backfill.
