Battery Mineral Resources Corp. Announces the Approval of Its Environmental Permit for Mining at Cinabrio and San Andres at its Punitaqui Copper Mining Complex

Vancouver, September 7, 2022 - Battery Mineral Resources Corp. (TSXV: BMR) ("BMR" "Battery" or the "Company") is very pleased to announce that it has received public approval by the Chilean Environment Assessment Service ("SEA") for the Environmental Impact Declaration ("DIA") pertaining to mining at its Cinabrio and San Andres deposits. The approval of the DIA allows BMR to be on schedule to move forward with starting mining operations in Q4 of this year and copper mineral processing activities at its Punitaqui complex in early 2023.

The DIA is an environmental permit which grants the permission to mine at a rate of up to 100,0000 tonnes per month (~ 3,333 tonnes per day) at the Cinabrio/San Andres area at its Punitaqui copper mining complex. The DIA permit covers aspects not only related to environmental considerations, but also social, health, flora, fauna, paleontology, amongst other items. With the DIA approval in hand the next step is to obtain the exploitation permit, which has been submitted for approval to the National Geology and Mining Service (SERNAGIOMIN).

Battery's CEO and director, Martin Kostuik states, "we are extremely pleased to have the DIA for Cinabrio, and San Andres approved. The application for mining operations has been submitted and is on schedule for approval in the next two months. In addition, our DIA permit application to transition from thickened tailings deposition to filtered (dry stack) tailings deposition is being submitted this month. This is well supported by the regulators as it will allow the Punitaqui operations to greatly reduce its consumption of water. On behalf of the Board of Directors of the Company I'd like to thank our team in Chile and the SEA for all their hard work in accomplishing this major milestone for the company ahead of schedule."
