MONGOOSE MINING ANNOUNCES APPOINTMENT OF INDEPENDENT DIRECTOR

Mongoose Mining Ltd. has appointed Hon. Labi Kousoulis, FCPA, ICD.D, to its board of directors as an independent director, effective immediately.

The appointment follows a review of the company's board composition led by the chairman of the board, with a focus on strengthening independent oversight, financial expertise and governance capacity as the company advances its strategic objectives.

Mr. Kousoulis is a fellow chartered professional accountant (FCPA) and holds the Institute of Corporate Directors designation (ICD.D). He brings extensive senior leadership experience within the government of Nova Scotia, where he held responsibility for economic development, finance, trade and capital investment programs, including oversight of large-scale public capital allocation initiatives. His experience provides the board with direct insight into provincial policy development, regulatory processes, intergovernmental co-ordination, and stakeholder engagement frameworks relevant to long-duration resource development in Nova Scotia.

Matthew Allas, chairman of the board, commented:

"Labi brings a practical understanding of how complex initiatives move from concept to execution within a provincial context. That perspective enhances the board's ability to evaluate opportunities, anticipate constraints and make more informed long-term decisions."

Mr. Kousoulis has no material relationship with the company and qualifies as an independent director under applicable securities laws and exchange policies. He will be eligible to serve on board committees as determined by the board.
