Fort St. James to Drill Multiple High-Priority VMS Targets Including Historic 13.6% Zn / 8.15% Pb Zone at Nepisiguit, Within Bathurst Mining Camp - Northern New Brunswick

Vancouver, British Columbia--(Newsfile Corp. - December 3, 2025) - Fort St. James Nickel Corp. (TSXV: FTJ) ("FTJ" or the "Company") is pleased to announce it is planning a diamond drilling program for 2026 at the Nepisiguit Property, located in the famous Bathurst Mining Camp in northern New Brunswick.

"With historic intercepts exceeding 13% zinc and 8% lead, and several untested targets across the property, we believe Nepisiguit is poised for a major breakthrough. This upcoming drill program is a significant step toward unlocking that potential," - Barry Brown, President.

FTJ has compiled historical exploration information for the property and has identified multiple target areas for exploration for volcanogenic massive sulfide deposits including four priority targets areas. The Company is planning a 1000-meter diamond drilling program during 2026 at the property. The Nepisiguit Property borders the Heath Steele Property of Glencore Canada Corp, site of the historic Heath Steele Mine.

During 2021, the Company announced it had entered into a letter of intent agreement with a private company to acquire 100% interest in the Nepisiguit Base Metal - Precious Metal Property located within the Bathurst Mining Camp of northern New Brunswick. The property consists of one mineral claim (claim no. 8116), covering an area of approximately 4,675 hectares. The term of the original letter of intent has been extended. A definitive agreement is expected to be negotiated between FTJ and the private company regarding the Nepisiguit Property now that FTJ has completed a due diligence review of the property and identified exploration targets.

The Company has incurred exploration expenditures on the Nepisiguit Property, including diamond drilling (six holes totaling 1,131 meters) during 2021 and prospecting and rock geochemical sampling; soil geochemical sampling; magnetometer geophysical surveys; and drill core sampling during 2021-2025. Magnetite iron formation with anomalous levels for lead and intervals of semi-massive pyrite were intersected in 2020-2021 drill holes in the east-central region of the property establishing a target area for the Company. Drill core sample analysis of magnetite iron formation intervals from two 2021 drill holes in this area revealed anomalous levels of lead in some samples. A 1.85 - meters long (core length) interval in drill hole NP-21-05 graded 2614 parts per million (ppm) lead (0.2614% Pb) and 32.0% iron. Four core samples (each 1.00 meters long - core length) from drill hole NP-21-06 returned lead values in the 3010 - 3110 ppm range (0.301 - 0.311% Pb) and iron values in the 24.0 - 35.1% range. FTJ is planning additional diamond drilling in this area.

FTJ has identified a target area for diamond drilling in the southern region of the Nepisiguit Property. Stratabound Minerals Corp. reported lead, zinc and copper mineralization in this area during 1997 - 1998. A 1998 drill hole reported in this area was reported to intersect 13.57% zinc and 8.15% lead over 0.20 meters core length; and 2.08% zinc and 0.88% lead over 2.00 meters core length (Lutes, 1998). FTJ has not verified this mineralization. FTJ has located two drill collars in this target area, interpreted by the Company as Stratabound holes 98-15 and 98-19. Hole 98-19 was reported to intersect near-surface intervals of anomalous lead and zinc including 0.69% zinc and 0.52% lead over 0.67 meters core length (Lutes, 1998).

FTJ has identified target areas for diamond drilling in the east region of the Nepisiguit Property. Major General Resources Ltd. reported geophysical anomalies (electromagnetic and induced polarization) in this region during 1996 and 2000 (LeBel, 1996 and Gill, 2000). FTJ has not verified these geophysical anomalies.

The Company is in the process of outlining a diamond drilling program for 2026 of approximately 1000 meters, testing some or all of these target areas.

While such estimates and assumptions are considered reasonable by the management of the Company, they are inherently subject to significant business, economic, competitive and regulatory uncertainties and risks. In particular, there is no guarantee that exploration work, as proposed, or otherwise, will be completed on the Company's properties.

Forward-looking statements are subject to a variety of risks and uncertainties, which could cause actual events, level of activity, performance or results to differ materially from those reflected in the forward-looking statements, including, without limitation: (i) risks related to commodity price fluctuations; (ii) risks and uncertainties relating to the interpretation of exploration results; (iii) risks related to the inherent uncertainty of exploration and cost estimates and the potential for unexpected costs and expenses; (iv) that resource exploration and development is a speculative business; (v) that the Company may lose or abandon its property interests or may fail to receive necessary licences and permits; (vi) that environmental laws and regulations may become more onerous; (vii) that the Company may not be able to raise additional funds when necessary; (viii) the possibility that future exploration, development or mining results will not be consistent with the Company's expectations; (ix) exploration and development risks, including risks related to accidents, equipment breakdowns, labour disputes or other unanticipated difficulties with or interruptions in exploration and development; (x) competition; (xi) the potential for delays in exploration or development activities or the completion of geologic reports or studies; (xii) the uncertainty of profitability based upon the Company's history of losses; (xiii) risks related to environmental regulation and liability; (xiv) risks associated with failure to maintain community acceptance, agreements and permissions (generally referred to as "social licence"); (xv) risks relating to obtaining and maintaining all necessary government permits, approvals and authorizations relating to the continued exploration and development of the Company's projects; (xvi) risks related to the outcome of legal actions; (xvii) political and regulatory risks associated with mining and exploration; (xix) risks related to current global financial conditions; and (xx) other risks and uncertainties related to the Company's prospects, properties and business strategy.
