In This Article:

Vancouver, British Columbia--(Newsfile Corp. - October 3, 2022) - Battery Mineral Resources Corp. (TSXV: BMR) ("BMR" "Battery" or the "Company") is very pleased to announce that it has filed a technical report for its NI 43-101 resource estimate at Punitaqui on SEDAR. This report is authored by JDS Mining and Energy Inc. ("JDS").

The technical report includes sections pertaining to the project history, geology, exploration, drilling, adjacent properties, sampling, QA/QC, data validation, metallurgy, mineral resources, conclusions, and recommendations as well as other required sections. The main highlight is the indicated and inferred resources which can be seen in the Table 1, below.

Notes to the Sulphide Mineral Resource Estimate Table

  • Prepared by Garth Kirkham (Kirkham Geosystems Ltd.) an Independent Qualified Person in accordance with NI 43-101.

  • Effective date: August 16, 2022. All mineral resources have been estimated in accordance with Canadian Institute of Mining and Metallurgy and Petroleum ("CIM") definitions, as required under NI 43-101.

  • Mineral Resources reported demonstrate reasonable prospect of eventual economic extraction, as required under NI 43-101. Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. The Mineral Resources may be materially affected by environmental, permitting, legal, marketing, and other relevant issues.

  • Cut-off grades are based on a price of US$3.50/lb copper, US$20/oz silver and several operating costs, metallurgical recoveries, and recovery assumptions, including a reasonable contingency factor.

  • Historic work at the Cinabrio Mine did not include silver analyses therefore silver grades are assumed to be at a null grade for the purpose of completeness however, it is reasonable to assume that silver grades will be at a similar tenor as Cinabrio Norte.

  • An Inferred Mineral Resource has a lower level of confidence than that applying to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration.

  • Resources reported for Cinabrio, San Andreas, Cinabrio Norte and Dalmacia are reported with internal dilution applied but are not fully diluted.

Note that all four zones of the resource estimate (the Cinabrio mine, the Cinabrio Norte zone, the San Andres zone and the Dalmacia zone) have underground access previously established by prior operators of the Punitaqui mine complex.
