First Mining Gold Drilling 18,000m to Grow Multimillion Ounce Gold Resource at Duparquet Project

• First Mining Gold is launching an 18,000m exploration drill program at its Duparquet Gold Project in Quebec, the largest program since acquiring the project in 2022.
• The drilling will focus on advancing priority targets aligned with resource growth potential to unlock regional gold endowment and support future development options.
• Previous drilling at Duparquet over the past two years, totaling 20,000m, has discovered new zones, demonstrated resource extension potential and delineated higher-grade areas.
• The 2025 exploration program is underpinned by a robust geoscience foundation including airborne geophysics, geological modeling, and field prospecting.
• First Mining believes the Duparquet Project has significant exploration upside and a systematic geoscience approach can further unlock value.

First Mining Gold Corp. (TSX:FF) is a gold developer advancing two of the largest gold projects in Canada - the Springpole Gold Project in Ontario and the Duparquet Gold Project in Quebec. The company, established in 2015, also owns the Cameron Gold Project in Ontario and a portfolio of other gold projects. First Mining is led by founding CEO Keith Neumeyer, who previously founded First Majestic Silver Corp.

Duparquet Gold Project Overview

The Duparquet Gold Project, located in the Abitibi region of Quebec, is a key focus for First Mining. Acquired in 2022, the project hosts 3.44 million ounces of Measured & Indicated gold resources at 1.55 g/t Au, plus 2.64 million ounces of Inferred resources at 1.62 g/t Au. A 2023 Preliminary Economic Assessment demonstrated the project's potential.

Duparquet spans about 5,800 hectares with 19 km of strike length along the prolific Destor-Porcupine Fault Zone. It includes the past-producing Beattie, Donchester and Duquesne mines and the Central Duparquet, Dumico and Pitt Gold deposits. The project benefits from existing road, rail and power infrastructure.

Largest Exploration Program Underway

First Mining is excited to launch an 18,000 m drill program at Duparquet in 2025, nearly doubling the 20,000 m drilled since acquiring the project. CEO Dan Wilton stated in the news release:

"We are excited to embark on a new exploration program that will almost double the amount of drilling completed to date since First Mining acquired the Duparquet Project in 2022. We are keen to further advance upon a number of significant exploration opportunities at Duparquet and are extremely excited about potential new catalysts for growth for this important project located in the heart of the Abitibi gold region."

The drill program will advance priority targets aligned with resource growth potential to unlock the regional gold endowment. This builds on successes from the previous two years of drilling which discovered new zones (Miroir, Aiguille, Buzz), demonstrated resource expansion potential along strike and at depth (Valentre, North Zone, DCD and East Extension), and delineated higher grade zones (CDHG, Valentre, North Zone).

Robust Geoscience Foundation

The 2025 exploration strategy is supported by an extensive geoscience framework developed over the past two years:

• Property-wide, high-resolution airborne geophysical and LiDAR survey
• Two-phase 3D geological modeling integrating key features across the entire project
• Summer field prospecting and mapping campaigns to refine regional targets

The 2025 exploration programs at the Duparquet Project will be focused on further defining and characterizing the controls on mineralization, as well as drill testing the extent of the mineralization at the newly discovered Miroir and Aiguille targets and further advancing and testing up to four resource expansion targets at depth and along strike.

Drilling will initially target the Miroir discovery zone, followed by Valentre-Dumico and East Extension. A second rig is planned to be added in Q2 to drill the North Zone, Buzz, Miroir, Aiguille, and South Zone targets. The vast majority (15,000 m) of the 18,000 m program will be completed in this second phase.

For Investors

The 2025 exploration program at the Duparquet Gold Project marks an ambitious step forward for First Mining Gold to realize the exceptional potential it sees in the project. With a resource base of over 6 million ounces and many attractive targets, the company is confident that continued exploration success can drive resource growth and unlock further value.

For investors, First Mining offers exposure to two advanced and large-scale development projects in top tier mining jurisdictions. With a respected leadership team, strong financial position, and value-driven growth strategy, the company represents a compelling opportunity in the gold development space. The Duparquet exploration program will be a key catalyst to watch in 2025.
