First Mining Intersects 7.18 g/t Au over 8 m at the Miroir Target and Provides Duparquet Project Update
First Mining firms up Duparquet footprint as environmental baseline work signals shift toward formal permitting
The most recent news (March 9, 2026) reports final results from the 2025 drilling program at the Duparquet Gold Project in Quebec. Key intercepts at the Miroir target include 7.18 g/t Au over 8.0 m and 30.58 g/t Au over 1.65 m. The program totaled 16,577 meters and successfully extended mineralization to a vertical depth of 250 m. Additionally, the company has officially commenced environmental baseline data collection at Duparquet, a critical step for the regulatory approval process.
The impact is Routine - Positive. While the drill grades are high (specifically the 30.58 g/t intercept), they are incremental to a project that already hosts a massive 3.44 Moz M&I resource. - Resource Growth: The results confirm that Miroir is a viable area for resource expansion, but they do not yet fundamentally alter the global resource scale. - Permitting Progress: The commencement of environmental baseline studies is a standard but necessary milestone for any developer. It indicates management is serious about moving Duparquet toward a Feasibility Study, mirroring the path taken at Springpole. - Consistency: The results are in line with previous 2025 updates (Sept/Nov 2025) which also showed consistent near-surface mineralization.
First Mining Gold is a Canadian developer focused on two Tier-1 assets: - Springpole (Ontario): One of the largest undeveloped open-pit gold deposits in Canada. The 2025 PFS outlines an after-tax NPV5% of $2.1B USD at $3,100/oz gold, with a 9.4-year mine life producing ~281k oz/year. - Duparquet (Quebec): A multi-million ounce resource (3.44 Moz M&I) located in the heart of the Abitibi, currently undergoing aggressive exploration to improve project economics.
