• Disruptions in the global economy from trade barriers, such as tariffs, could adversely affect the Company's business, financial condition, or results of operations.
• Continued negative cash flows from operating activities could lead to future losses and adversely affect the market price of the Company's securities.
• There is no assurance that an active or liquid trading market for the Common Shares will be sustained, potentially affecting share prices.
• The market price of the Company's securities can be subject to significant fluctuations due to financial results, stock market volatility, and geopolitical events.
• Future issuances of additional securities will dilute voting power and may dilute earnings per share, potentially causing downward pressure on share price.
• Management has broad discretion in the use of net proceeds from offerings, and ineffective application could lead to financial losses.
• There is no public market for Preferred Shares, Warrants, Subscription Receipts, or Units, which may affect their liquidity and pricing.
• United States investors may face difficulties enforcing judgments obtained in U.S. courts against the Company or its foreign-resident directors/officers due to Canadian jurisdiction.

Future Outlook

The Company intends to utilize the shelf prospectus to raise capital from time to time for general corporate purposes, including funding ongoing operations, working capital, capital projects, and potential future acquisitions. It aims to advance its material assets, the Springpole and Duparquet Projects, towards construction decisions and ultimately to production. The Springpole Project is expected to have a mine life of 9.4 years after one year of pre-production stripping. Work to transfer material for the Duparquet storage pad is planned for completion in 2026, with construction continuing through 2026. The sale of FireFly's 70% interest in the Pickle Crow Project is expected to close in Q2 2026, and the Cameron Gold Amalgamation is expected to close in Q1 2026.

Management Comments

• Our vision is to advance its material assets towards a construction decision and, ultimately, to production.
• We believe that the expectations reflected in any forward-looking statements are reasonable, but no assurance can be given that these expectations will prove to be correct.
• We believe we are in substantial compliance with all material laws and regulations which currently apply to our activities.

Industry Context

StockSavvy.ai notes that the filing of a base shelf prospectus is a common strategic move for exploration and development companies in the mining sector, providing financial flexibility to capitalize on market opportunities or fund project advancements without immediate, fixed-term commitments. The focus on Canadian gold projects aligns with Canada's reputation as a stable mining jurisdiction. The emphasis on Indigenous community agreements (LTRA with Mishkeegogamang) reflects a growing industry trend towards stronger social license to operate, which is crucial for project de-risking and long-term sustainability in resource development. The updated PFS for Springpole, with its robust economics, positions it as a potentially significant future gold producer, contrasting with the general challenges faced by junior miners in bringing projects to production.

Comparison to Industry Standards

• The Springpole Project's post-tax IRR of 40.9% and NPV5% of US$2,150 million (at US$3,100/oz gold) are highly attractive compared to many gold development projects globally, which often target IRRs in the 20-30% range. For example, projects like Seabridge Gold's KSM Project or Skeena Resources' Eskay Creek Project have strong economics but often with higher initial capital expenditures and longer payback periods.
• The All-in Sustaining Cost (AISC) of US$937.9/oz Au for Springpole is competitive within the current gold mining industry, where many established producers report AISC figures ranging from US$1,000/oz to US$1,500/oz. This suggests potential for strong margins if gold prices remain elevated.
• The 1.8-year post-tax payback period for Springpole is exceptionally fast for a large-scale mining project, indicating strong capital efficiency and rapid return on investment compared to industry averages which can be 3-5+ years for similar-sized developments.
• The resource base of 8.7 million ounces of gold in Measured and Indicated categories positions First Mining Gold as a significant developer, comparable to mid-tier exploration companies like Osisko Mining or Great Bear Resources (prior to acquisition) in terms of resource scale, though these companies may have different development stages or project types.

Key Dates

Recommendation

The updated Pre-Feasibility Study for the Springpole Gold Project presents exceptionally strong economics with a high IRR (40.9% post-tax) and a very short payback period (1.8 years), indicating a highly robust and attractive development project. The successful negotiation of a Long-Term Relationship Agreement with the Mishkeegogamang Ojibway First Nation significantly de-risks the project's social license, a critical factor in mining. While the company is still in the development stage with negative operating cash flows, the substantial resource base and the clear path to production for Springpole, coupled with the financial flexibility provided by the shelf prospectus, make this a compelling investment opportunity for long-term growth in the gold sector. The current share price of $0.61 on February 20, 2026, appears to undervalue the project's potential given the strong PFS results.
