Highlights:

• Winsome Resources signs binding agreement to purchase Hong Kong-based Sinomine's interests in Power Metals Corp.'s Case Lake Project

VANCOUVER, Dec. 2, 2022 - Power Metals Corp. ("Power Metals" or the "Company") (TSXV: PWM) (FRANKFURT: OAA1) (OTCQB: PWRMF) is pleased to announce that Winsome Resource Limited (ASX: WR1) ("Winsome") has agreed to acquire shares in TSX-V listed Power Metals Corp. that are currently owned by Hong Kong-based Sinomine Rare Metals Resources Co Ltd ("Sinomine").

Under this agreement, Winsome has also agreed to acquire Sinomine's offtake rights for the lithium, cesium and tantalum from the highly prospective Case Lake Project ("the Project"), located in Ontario, Canada.

The Project is 100% owned by Power Metals and hosts high-grade deposits of cesium, lithium and tantalum. All three minerals are included on the latest US and Canadian critical minerals lists.

Located in north-eastern Ontario approximately 100km north of Kirkland Lake, the Project is accessible year-round via the Translimit Road which connects Ontario and Quebec.

As previously directed by the Canadian government (See press release dated November 3, 2022), Sinomine is required by recent changes to Canadian law to divest its interests in the Project.

Under the terms of the agreement, for a total cash consideration of CAD$2,000,000 (AUD$2,220,000)(CAD $0.27 per share of Power Metals stock) Winsome will acquire Sinomine's total interests in Power Metals and the Case Lake Project, including:

• 7,500,000 common shares; and
• 7,500,000 share purchase warrants, which can be converted into shares on a one-for-one basis at CAD$0.40 per Share, expiring on 17 March 2025,

(together, the "Sale Securities")

Winsome has also agreed to assume all of Sinomine's rights and obligations under the offtake agreement that was signed between Sinomine and Power Metals dated 16 March 2022 ("Offtake Rights").

Winsome's acquisition of the Sale Securities is subject to the following conditions precedent:

• Execution and delivery of a deed of assignment by Sinomine and Winsome in relation to the Offtake Rights, effective from completion of Winsome's acquisition of the Sale Securities; and
• Sinomine obtaining all necessary shareholder and regulatory and approvals and third-party approvals and consents necessary to lawfully complete the matters set out in this Agreement.

It is expected that the Company's acquisition of the Sale Securities and the Offtake Rights will occur on or about 2 December 2022

Winsome will utilize its existing cash reserve to fund the acquisition. This is consistent with the Company's announcement dated 15 August 2022, in which it is stated that, to the extent that Winsome is presented with additional acquisition opportunities, Winsome's working capital will fund the acquisition costs.

Winsome and Power Metals have commenced strategic discussions aimed at utilizing the resources available to both Companies to facilitate the rapid development of the Case lake Project and build upon the >13,000m of drilling already completed at the site to publish a maiden resource as soon as possible. Additionally, the Companies are in negotiations regarding Winsome assuming the position currently held by Sinomine on the Power Metals Board of Directors.

WINSOME RESOURCES MANAGING DIRECTOR CHRIS EVANS STATED:

"This is an exciting opportunity for Winsome to expand its interests in the Canadian critical minerals space and to enter the established mining province of Ontario, which neighbours Quebec.

"The Case Lake Project is located in relatively close proximity to a number of our assets, in particular Mazerac and Decelles, with similar geological characteristics and strong drill results showing high-grade caesium, lithium and tantalum mineralisation.

"The minerals are all in high demand within North America and the rights to the offtake agreement are another positive step in the Winsome journey. We look forward to working with Power Metals to assist in developing this impressive project"

Chairman & CEO, Johnathan More stated, "Power Metals is thrilled to welcome Winsome Resources to the family. We look forward to jointly developing our tremendous Case Lake property. Furthermore, we will also be providing more drill results from our ongoing drill program in the very near future."
