Battery Mineral Resources Corp. Announces Resumption of Copper

Concentrate Production at Punitaqui

Vancouver, British Columbia – (May 13, 2024) – Battery Mineral Resources Corp.

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

to announce the resumption of mill operations and first production of copper

concentrates at its Punitaqui project in Chile.

Martin Kostuik, Battery’s CEO stated, "The commencement of copper concentrate

production at Punitaqui marks a significant milestone for BMR and in establishing

Chile's next copper mine. Having efficiently applied capital, it has paved the way for

near term copper production at Punitaqui and positioning the company favorably to

generate meaningful cash flow. With the commencement of copper concentrates

production, a proficient operational team, and a promising outlook for robust copper

markets, we aim to enhance shareholder value further. We eagerly anticipate sharing

our progress and results as 2024 progresses."

Operational Highlights 2024

The Company has initiated copper concentrate production after the successful

commissioning of the recently refurbished and upgraded mineral processing facility

at Punitaqui. Mining activities to establish access to the mineralized zones in both

Cinabrio and San Andres continue to ramp up with stockpiling of fresh mill feed .

Cinabrio is the original mine that supplied feed for the first 10 years of prior

operations, primarily by Glencore plc.

During the ramp up period of the mines, the Company is looking to boost the revenue

stream by processing mill feed from external sources. Supply to the mill over the

coming months will be a combination of fresh material from the Punitaqui mines and

feed from outside sources including material from private mines in the area , and

copper smelter slags.

Anglo-American Agreement

The source of slags supply is m ade possible by the Anglo-American PLC (“Anglo”)

agreement announced on February 13th, 2024. Anglo has agreed to purchase all the

copper concentrate to be produced from 240,000 tonnes of Anglo -supplied copper

smelter slags.

Milestones

The timeline from first fresh mine feed through the mill to reaching planned

capacity is expected to require approximately nine months, reaching a run rate of

~90,000 tonnes per month. BMR expects that the Punitaqui full annual copper

production rate will be in the range of 19 million to 23 million pounds of copper in

concentrate with an operating margin of $35 million to $50 million at current

copper prices.

While the Cinabrio and San Andres mines are reaching full production, the Company

will continue processing mill feed from outside sources and advancing toward its

newly discovered Cinabrio Norte zone, to commence production of mill feed from that

zone in H2 2025.

As part of the ongoing operational readiness during 2024, BMR is executing

underground infill and extensional drilling at San Andreas and Cinabrio. The drilling

program is designed to further define areas that could be included in near-term mine

sequencing and for grade control purposes. The company looks forward to reporting

the results of this drilling during the course of the year.

C$549,360) private placement (the “ Private Placement ”) of senior unsecured
