Red Lake Gold Inc. Positions for Strong Copper Market with the Soo North Copper Project; Adjacent Sterling Metals Corp.'s Soo Copper Project

Vancouver, British Columbia--(Newsfile Corp. - October 7, 2025) - Red Lake Gold Inc. (CSE: RGLD) ("Red Lake Gold" or the "Corporation" or the "Issuer") is pleased to announce that it has acquired an inaugural copper exploration project, the Soo North Copper Project (the "Soo North Copper Project" or "Soo North") situated in Ontario, Canada.

As reflected in today's announcement regarding the Soo North Copper Project, the Issuer has interest in conducting copper exploration noting that copper prices sit near record highs, with the London Metal Exchange (LME) copper cash settlement being at approximately US$10,610 per tonne as of October 6, 2025, approaching the record high set in May 2024. The Issuer is of the opinion that copper's pricing dynamics may help facilitate a continued strong near-term market for the commodity.

Soo North Copper Project - Overview

The Soo North Copper Project is a large copper exploration project situated directionally north of Sault Ste. Marie, Ontario, and, at its formation, the project comprises a total of 416 mining claims covering approximately 9,142 ha (the latter as measured by QGIS).

Prompt acquisition of the Soo North Copper Project was guided by a newly announced high-grade copper discovery drill intercept at a (now-adjoining) third-party project. Specifically, the Soo North Copper Project is contiguously located (along a significant east-west claim-boundary) to Sterling Metals Corp. ("Sterling Metals")(see Figure 1 below), which recently reported drill results (highlighted by drillhole MEPS-25-02) at their adjacent Soo Copper Project (the "Sterling Metals Copper Discovery")(see news release by Sterling Metals Corp., Sterling Metals Announces High-Grade Copper Discovery at the Soo Copper Project Intersecting 262.5m of 1.05% CuEq, Including 68.3m of 3.25% CuEq and 9.3m of 19.8% CuEq from Near Surface, dated September 29, 2025).

Importantly, the Issuer credits its success in acquiring the Soo North Copper Project to its same-day work around news of the Sterling Metals Copper Discovery, and the Issuer has now subsequently paid the applicable Crown staking fees to the Government of Ontario.

As a result, the Issuer owns a 100% interest in the Soo North Copper Project, without any third-party share or cash property earn-in payments due under an industry-commonplace option agreement. To this, the Issuer's first-mover advantage presents reduced dilution advantages versus earn-in burdens prospectively faced by other regional entrants that may be now examining the area. Moreover, the Issuer's new copper exploration project is held on a royalty-free basis (save to the Crown), providing it additional flexibility around project development, as well as shareholder upside.
