BATTERY MINERAL RESOURCES ANNOUNCES THIRD SHIPMENT OF COPPER

CONCENTRATES PRODUCED AT ITS MINERAL PROCESSING FACILITY AT PUNITAQUI ,CHILE

Vancouver, British Columbia – (September 9th, 2024) – Battery Mineral Resources Corp.

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

the third shipment of copper concentrate s produced at its mineral processing facility at

Punitaqui, Chile.

The Company supplied 1,198 dry metric tonnes (“DMT”) of copper concentrates in the month

of August. 351 DMT were delivered to Anglo’s Chagres smelter in Catemu, Chile and are

related to the Offtake Agreement (or the “Agreement”) with Anglo American Sur S.A. (“Anglo”

or “Anglo American”), a division of Anglo -American PLC. The copper concentrates were from

copper smelting by-products (slags) supplied to BMR by Anglo. The balance, being 847 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 in the month of August were produced at BMR’s Punitaqui

copper flotation plant and contained a weighted average of 23.91 percent copper, for

approximately 631,400 pounds of copper in concentrate.

Martin Kostuik, C hief Executive Officer, stated, "This third shipment of copper concentrate

marks another significant milestone for Battery Minerals , with 847 DMT sourced from our

own Punitaqui mine operations. We are progressing well on ramping up material sourced from

the Punitaqui mines and continuing to find new opportunities for additional third-party mill

feed. We look forward to persistently increasing value to stakeholders through growing cash

flows from copper sales.”

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

facility at Punitaqu i, t he Company has shipped 2,453 DMT, for a total of over 1,326,000

pounds of copper in concentrate, to date . The Company is progressing steadily to bolster

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 year-end.

Mining activities are focussed on establishing access to the mineralized zones in both

Cinabrio and San Andres. Activities continue to ramp up with both mines providing increasing

amounts of stockpiles containing fresh mill feed. Cinabrio is the original mine that supplied

mill feed for the first 10 years of prior operations, primarily operated by Glencore PLC.
