Battery Mineral Resources Corp. Announces Delay of Annual Filings

Vancouver, April 29, 2022 - Battery Mineral Resources Corp. (TSXV: BMR) (OTCQB: BTRMF) ("Battery" or "BMR" or the "Company") announces that it will delay the filing of its annual financial statements and accompanying management's discussion and analysis and related CEO and CFO certificates for the financial year ended December 31, 2021 (collectively, the "Annual Filings"). Filing is required within 120 days of the financial year-end, under applicable Canadian securities laws. As further described below, the Company expects to file the Annual Filings by May 17, 2022.

Primarily, certain equity transactions related to the ESI Energy Services Inc. common control acquisition for prior fiscal year are being restated. The Company is working on the restatement of its 2020 financial statements and intends to file its 2021 financial statements along with restated 2020 comparative information. The restatement of the 2020 financial statements is not expected to have an impact on cash, or loss for the period from continuing operations in the financial statements. The Company retained PricewaterhouseCoopers LLP ("PwC") for the 2021 year-end audit and on a go-forward basis, replacing its former auditor.

As a result of the delay, the Company has submitted an application for a Management Cease Trade Order ("MCTO") under National Policy 12-203 - Management Cease Trade Orders ("NP 12-203") in respect of the default, which is subject to approval by the British Columbia Securities Commission. If granted, the MCTO would not in any way impact the ability of shareholders and investors to engage in the trading of BMR's common shares.

Battery CEO Martin Kostuik states: "BMR changed auditors as an important part of the many steps we are taking to prepare the Company for the transformation from a development-stage to a cash-flowing entity. We are restating certain transactions related to our acquisition of ESI. PwC, our new auditors, need more time to complete their audit given these restatements. We are confident that these are a one-time change in filings, that they will be finalized soon and we do not expect that they will have any impact on cash or loss for the period from continuing operations."

The Company expects to file the Annual Filings by May 17, 2022, and will issue a news release once the Annual Filings have been filed. Until the Company files the Annual Filings, it will comply with the alternative information guidelines set out in NP 12-203. The guidelines, among other things, require the Company to issue bi-monthly default status reports, in the form of news releases, for so long as the Annual Filings have not been filed.

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, 2021 of the Company's latest interim financial reports for the period ended September 30, 2021.
