Battery Mineral Resources Delivers Copper Concentrates Produced at Its Mineral Processing Facility at Punitaqui, Chile

BATTERY MINERAL RESOURCES DELIVERS COPPER CONCENTRATES PRODUCED AT ITS

MINERAL PROCESSING FACILITY AT PUNITAQUI, CHILE

Vancouver, British Columbia – (December 16th, 2024) – Battery Mineral Resources Corp.

(TSXV: BMR) (OTCQB: BTRMF) (“Battery” or “BMR” or the “Company”) is pleased to

announce the continued production and shipment of copper concentrates produced at its

mineral processing facility at Punitaqui, Chile.

The Company supplied a total of 2,755 dry metric tonnes (“DMT”) of copper concentrates in

the months of September, October and November 2024. 1,131 DMT were delivered to Anglo

American Sur S.A.’s Chagres smelter in Catemu, Chile and are related to the Offtake

Agreement (or the “Agreement”) with Anglo American Sur S.A. (“Anglo”), a division of Anglo-

American PLC. The copper concentrates were from copper smelting by-products (slags)

supplied to BMR by Anglo. The balance of the copper concentrates, being 1,624 DMT, were

produced from Battery’s own Punitaqui mine operations and were sold to Ocean Partners

Chile SpA and delivered to Terminal Portuario de Coquimbo (“TPC”) to be exported. TPC is a

major export and import point in Chile, handling a significant amount of the copper

concentrates produced within the country, and is located approximately 130 kilometers from

the mine by paved road with year-round access.

All of the copper concentrates during those three months were produced at BMR’s Punitaqui

copper flotation plant and contained a weighted average of 22.33 percent copper, for

approximately 1,235,000 pounds of copper in concentrate.

Martin Kostuik, Chief Executive Officer, stated, "The ongoing production and shipment of

copper concentrate represents important progress in achieving our goal of 1,400 DMT per

month, in the near term. The funds received from our recent transaction with Electric

Royalties, combined with the increasing concentrate sales and requisite cash flows, will

enable Battery to continue ramping up the supply of mill feed from our own Punitaqui mines.”

Since the May 2024 commissioning of the recently refurbished and upgraded mineral

processing facility at Punitaqui, the Company has shipped 5,661 DMT, for a total of over

2,783,565 pounds of copper in concentrate, to date. The Company is progressing steadily to

bolster copper concentrate production results with a goal of delivering approximately 1,400

DMT per month in the near term and reaching up to 2,800 DMT of copper concentrate

production per month by 2H 2025.

Continued mining activities are providing access to the mineralized zones in both Cinabrio

and San Andres. Battery continues to ramp up with both mines now providing increasing

amounts of stockpiles containing fresh mill feed.
