Copper Concentrate Production and Outlook
Environmental & Sustainability Progress
Vancouver, British Columbia – (October 16th, 2025) – Battery Mineral Resources Corp. (TSXV:
BMR) (OTCQB: BTRMF) (“ Battery” or “BMR” or the “ Company”) is pleased to update its
shareholders on operational improvements at the Punitaqui Copper Project (“Punitaqui”) in
Chile.
Laz Nikeas, CEO of BMR, stated, “We are pleased to share an update on our growing copper
production at Punitaqui . BMR’s primary focus continues to be on maximizing concentrate
throughput to generate cash flow. We are encouraged by the strong operating performance
at Punitaqui over the past six weeks. Our team in Chile has taken a disciplined approach to
extraction, plant optimization, and cost management that has delivered improving production
and financial results.
Since September 1st, 2025, the project has averaged approximately 1,800 tonnes of
production per day from the underground operations, an 80% increase compared to the first
half of 2025. Over the last two weeks, we have achieved average production of approximately
2,000 tonnes per day. The strong performance of our underground mobile equipment has
been instrumental in supporting production growth. In addition, our concentrate production
has featured robust copper grades as high as 32 % alongside notable gold and silver
byproduct credits. Punitaqui is currently positioned with approximately 50,000 tonnes of
stockpiled inventory, a first for our business. Our Los Mantos concentrate facility has the
capacity to process up to 3,500 tonnes per day.
We are also pleased to report that we are in the process of developing a third underground
operation at Cinabrio Norte to complement those operations currently in production at
Cinabrio and San Andres. In addition, we continue to progress work on our fourth
underground operation, Dalmacia. We will update the shareholders on both projects in the
near term.
I want to thank the operati ng team in Chile for working through numerous challenges to
deliver a clear positive shift in the Punitaqui asset performance. We look forward to providing
shareholders with additional favorable operating updates in the near term.”

2,374 dry metric tonnes (DMT) of copper concentrates. The concentrates averaged 25%
copper, amounting to approximately 1.8 million pounds of contained copper.
The Company’s near-term goal at Punitaqui is 2,500-2,700 DMT of copper concentrates per
month by the end of 2025, assuming favorable operating and metallurgical conditions . Our
copper concentrate production targets for full year 2025 and 2026 are 15,000-16,000 DMT
and 28,000–30,000 DMT , respectively , assuming favorable operating and metallurgical
conditions.
