First Mining Gold Reports Continued Success at Miroir Discovery

First Mining Gold Corp., trading under TSX: FF and OTCQX: FFMGF, has recently reported promising results from its ongoing exploration drilling at the Miroir target, part of the Duparquet Gold Project located in Quebec's Abitibi region. In its latest drilling campaign, the company demonstrated an ongoing commitment to exploration aimed at defining and expanding gold resources within this region.

Highlights of the Recent Drilling Campaign

The latest drilling efforts at Miroir have extended the target area, revealing high-grade gold intercepts. Notably, diamond drill hole DUP25-077 returned impressive results of 3.20 g/t Au over 15.75 meters, including exceptional values of 22.50 g/t Au over 0.7 meters. Another significant drill hole, DUP25-078, revealed 2.01 g/t Au over 29.8 meters, highlighting inclusions of 15.70 g/t Au over 0.75 meters within the larger intersection. Additionally, drill hole DUP25-079 reported 1.76 g/t Au over 16.25 meters. These intercepts underline the potential for further resource delineation within the Miroir target.

This exploration phase marks a crucial step, with First Mining completing 16,577 meters of drilling across the project by October 2025. To date, assay results from 14 of the 22 holes drilled have been disclosed, with the remaining results yet to be reported, generating anticipation for additional discoveries.

Geological Context and Mineralization Characteristics

The Miroir target is characterized by its proximity to the Central Duparquet - Valentre - Dumico target, a promising site located only 225 meters away. The continuation of near-surface mineralization demonstrates a robust continuity that enhances the scope of the Duparquet Project. The results show gold mineralization that remains open for further exploration, indicating an exciting potential growth area for First Mining.

CEO Dan Wilton commented on the results, stating, "The Miroir target has now been extended up dip in an attractive shallow mineralization setting while demonstrating strong continuity, a key characteristic of the Duparquet Project." These words reinforce the company's strategy of assessing various development scenarios as they progress with their exploration agenda.

Understanding the Miroir Target's Potential

The Miroir target is significant as it lies within a favorable geological setting. The mineralization is typically associated with syenite-basalt contacts, often revealing gold in brecciated silica-altered syenite and basalt with minor pyrite mineralization. The intersections recorded at Miroir highlight a depth range of up to 100 meters, making it accessible for further exploratory drilling.

The recently published results confirm the integrity of previous findings, establishing a consistent and high-potential mineralized zone. Exploratory drilling at Miroir has consistently yielded positive results, indicating not only the presence of gold but also the potential for economic viability.

Future Directions for First Mining Gold

With the close of the 2025 drilling program, First Mining is set to integrate the new data into 3D geological models to refine their exploration strategy for 2026. With a focus on near-surface potential and ongoing analysis of the mineralization controls, the company aims to enhance understanding and pave the way for future drilling.

Furthermore, First Mining continues to work towards the completion of its Preliminary Economic Assessment (PEA) while ensuring that community relationships and environmental responsibilities are prioritized as they advance the Duparquet Gold Project.

As more assay results are processed and interpreted, First Mining Gold is poised to update investors and stakeholders with further information that could significantly influence the impending development phases, underpinning their commitment to maintaining transparency and efficiency in operations.
