BATTERY MINERAL RESOURCES SECURES UNANIMOUS APPROVAL OF ENVIRONMENTAL

IMPACT STATEMENT FOR PUNITAQUI PROJECT

Vancouver, British Columbia – July 28, 2025) – Battery Mineral Resources Corp. (TSXV: BMR)

(OTCQB: BTRMF) ("Battery" or “BMR” or the "Company") is pleased announce that Minera

BMR SpA, the Company’s wholly-owned Chilean subsidiary, has received unanimous approval

of the Environmental Impact Statement (EIS) for the extension of the operational life of the

Los Mantos Copper Plant, located in the community of Punitaqui, Coquimbo Region, Chile.

This approval, granted by all relevant environmental authorities, marks a significant milestone

for the continuity of the Punitaqui Project. It enables operations to continue for up to an

additional ten years and supports the preservation and creation of hundreds of direct and

indirect jobs in the communities of Punitaqui and Ovalle.

BMR’s General Manager, Fernando Rodriguez commented : “This result reflects our

commitment to responsible sustainable mining, that creates shared value for the

communities in which we operate. We are grateful to the authorities and the communities who

engaged constructively throughout the process.”

A key component of the project’s future is the construction of a new filtered tailings deposit,

which will allow the Company to (i) expand its workforce, which is currently approximately 300

employees, and (ii) to implement certain best-in-class environmental standards including

moving from conventional to dry-stack tailings.

The Company undertook a comprehensive revision of the project, addressing all observations

raised by key agencies including the Environmental Assessment Service (SEA), Ministry of the

Environment, General Directorate of Water (DGA), CONAF, and sectorial SEREMIs. The new

filing, submitted in June 2025, also includes enhanced mitigation, and community

participation measures.

Battery reaffirms its dedication to transparency, environmental stewardship, and ongoing

dialogue with stakeholders, as a committed partner in the sustainable development of the

region.
