Vancouver, British Columbia--(Newsfile Corp. - May 7, 2025) - Battery Mineral Resources Corp. (TSXV: BMR) (OTCQB: BTRMF) ("Battery" or "BMR" or the "Company") announces that the Company has been issued a cease trade order ("CTO") by the British Columbia Securities Commission ("BCSC") for missing the filing deadline of April 30, 2025 for the following periodic disclosure documents (collectively "Annual Filings"):

• the audited annual financial statements for the year ended December 31, 2024;

• the management's discussion and analysis relating to the audited annual financial statements for the year ended December 31, 2024; and

• the certification of the foregoing filings as required by National Instrument 52-109 – Certification of Disclosure in Issuers' Annual and Interim Filings.

The company has been delayed in making the Annual Filings, in large part due to the additional analyses required in accounting for certain financing and other transactions which occurred in 2024, as well as certain tax adjustments. The company anticipates making the Annual Filings in the near-term and will provide a further update to shareholders once the Annual Filings have been made. At the time of filing, a news release will be issued indicating that the Annual Filings have been submitted. Upon filing the Annual Filings, the Company expects that the CTO will be revoked within one to two business days (in Canada), as is the customary practice.

Despite the CTO, a beneficial security holder of the Company who is not, and was not at the date of the CTO, an insider or control person of the Company, may sell securities of the Company acquired before the date of the CTO if the following apply: (a) the sale is made through a "foreign organized regulated market", as defined in section 1.1 of the Universal Market Integrity Rules of the Investment Industry Regulatory Organization of Canada; and (b) the sale is made through an investment dealer registered in a jurisdiction of Canada in accordance with applicable securities legislation. Holders of the Company's securities are urged to consult with their own investment advisors or legal counsel about the implications of the CTO.

The Company confirms that, other than as disclosed in prior press releases and material change reports, there have been no material business developments since the filing on November 29, 2024 of the Company's latest interim financial reports for the period ended September 30, 2024.
