Power Metallic Appoints Retired Federal Minister Seamus O’Regan to Board

Former Minister of Energy & Natural Resources, Indigenous Services, Seniors, Labour, Veteran Affairs and Associate Minister of National Defence

TORONTO, Aug. 26, 2025 — Power Metallic Mines Inc. (the Company or Power Metallic) (TSXV: PNPN) (OTCBB: PNPNF) (Frankfurt: IVV) is pleased to announce the appointment of Seamus O’Regan to its board.

Seamus O’Regan Jr joined Stewart McKelvey, Atlantic Canada’s largest law firm, in March 2025 as Senior Business Advisor following a distinguished career in politics and journalism. He was first elected Member of Parliament for St. John’s South–Mount Pearl in 2015 and was re-elected in 2019 and 2021.

During his time in federal office, Mr. O’Regan served as Canada’s Minister of Energy & Natural Resources, where he oversaw the country’s first Critical Minerals Plan and the Critical Minerals List, the National Hydrogen Plan, and the Small Modular Reactor Action Plan. He also served as Minister of Indigenous Services, Minister of Labour, Minister for Seniors, Minister of Veterans Affairs and Associate Minister of National Defence.

Born in St. John’s, Newfoundland and raised in Goose Bay, Labrador, Mr. O’Regan studied politics at St. Francis Xavier University and University College Dublin, and marketing strategies at INSEAD. He completed a Master of Philosophy at the University of Cambridge in 1999, focusing on Indigenous participation in large-scale natural resource development.

Mr. O’Regan began his career in the Government of Newfoundland and Labrador as executive assistant to the Minister of Justice & Attorney General Edward Roberts and as policy director to Premier Brian Tobin. He later worked as a journalist for many years, notably hosting CTV’s Canada AM.

He is a Fellow of the Royal Canadian Geographical Society and has served on the boards of World Wildlife Fund Canada, Canada World Youth, Katimavik, The Company Theatre and The Rooms. He has also acted as an Ambassador for Bell Let’s Talk.

Power Metallic CEO Terry Lynch commented, “We are very pleased Seamus accepted our offer. His skillsets in government affairs, particularly his time as Energy & Natural Resources Minister and Minister of Indigenous Services, will be very helpful as we look to guide our High Grade Polymetallic (copper, platinum, palladium, gold, silver and nickel) discovery ‘Nisk’ at Nemaska, Quebec through exploration to development and toward what we hope will be the world’s first carbon-neutral polymetallic mine. Increasingly critical mineral projects like Nisk are vital not only for economic output but for the roles these materials play in defense, industrial and AI infrastructure. We look forward to utilizing the unique perspective and insights Seamus can provide.”

Mr. O’Regan said, “I’m excited about the Nisk discovery and how Power Metallic plans to bring this project to market. Canada is uniquely positioned to lead the world in these types of developments given our mineral wealth, expertise and geopolitical position. I look forward to working with the Power Metallic team to make this project a reality.”

Power Metallic is currently engaged in a 100,000-metre drill program. Four rigs are operating on the project with a fifth expected to be added in early September. Initial results from the summer campaign are expected shortly and thereafter every 2–4 weeks through the end of the year.

The Company has granted an aggregate of 1,150,000 incentive stock options at $1.45 per share to Mr. O’Regan and certain officers of the Company, exercisable for up to five years from the date of grant.

About Power Metallic Mines Inc.

Power Metallic is a Canadian exploration company focused on advancing the Nisk Project Area (Nisk–Lion–Tiger), a high-grade copper–PGE, nickel, gold and silver system, toward Canada’s next polymetallic mine.

On February 1, 2021, Power Metallic (then Chilean Metals) secured an option to earn up to 80% of the Nisk project from Critical Elements Lithium Corp. Following the July 2025 purchase of 313 adjoining claims (~167 km²) from Li–FT Power, the Company now controls approximately 212.86 km² and roughly 50 km of prospective basin margins.

Power Metallic is expanding mineralization at the Nisk and Lion discovery zones, evaluating the Tiger target, and exploring the enlarged land package through successive drill programs.

Beyond the Nisk Project Area, Power Metallic indirectly holds interests in significant land packages in British Columbia and Chile through a 50% share ownership position in Chilean Metals Inc., which was spun out via a plan of arrangement on February 3, 2025.

The Company also owns 100% of Power Metallic Arabia, which holds a 100% interest in the Jabul Baudan exploration license in Saudi Arabia’s Jabal Said Belt. That property encompasses over 200 square kilometres in a region recognized for copper, gold and zinc prospectivity, including volcanic massive sulfide (VMS) deposits such as the Jabal Sayid mine.
