Foran Mining Corp.: Expansion Potential Builds with New Tesla Zone Drill Results

Vancouver, BC (September 4, 2025) – Foran Mining Corporation (TSX: FOM) (OTCQX: FMCXF) (“Foran” or the “Company”) is pleased to announce results from the final 15 holes drilled as part of its 2025 winter-spring drill program at the Tesla and Bridge Zones, part of the Company’s 100%-owned McIlvenna Bay Project located in east-central Saskatchewan.

Key Highlights:

⦁ Drilling confirms mineralization across multiple areas of the Tesla Zone. Foran completed almost 28,500 metres of drilling across 32 holes at the Tesla and Bridge Zones during the winter-spring drill program. All holes successfully intersected copper- and/or zinc-rich mineralization, with several results also returning notable gold and silver values.

⦁ Highlight intercepts from the 15 holes released today include:

⦁ 6.9m grading 2.16% Cu, 3.72% Zn, 29.3 g/t Ag and 0.62 g/t Au (3.58% CuEq) from TS-25-38w2

⦁ 17.1m grading 2.07% Cu, 0.67% Zn, 27.5 g/t Ag and 0.37 g/t Au (2.43% CuEq) from TS-25-38w2

⦁ 8.1m grading 1.86% Cu, 11.51% Zn, 80.9 g/t Ag and 1.68 g/t Au (6.49% CuEq) from TS-25-37w2

⦁ 19.9m grading 0.56% Cu, 7.89% Zn, 40.2 g/t Ag and 0.29 g/t Au (3.23% CuEq) from TS-25-40w2

⦁ 16.5m grading 2.20% Cu, 1.39% Zn, 11.5 g/t Ag and 0.03 g/t Au (2.49% CuEq) from BZ-25-02w1

⦁ Precious metals opportunity emerging. Elevated gold and silver grades have been observed in several holes in the central part of the Tesla Zone. Highlight intercepts from this target include:

⦁ 3.3m grading 3.42% Cu, 8.72% Zn, 87.8 g/t Ag and 3.12 g/t Au (7.94% CuEq) from within TS-25-

37w2’s 8.1m intersection above, which included one of the highest single-sample gold assay grades received to date, with 0.5m grading 13.89 g/t Au, 107.0 g/t Ag, 4.15% Cu and 7.20% Zn (14.50% CuEq)

⦁ 7.0m grading 0.06% Cu, 0.02% Zn, 85.3 g/t Ag and 0.83 g/t Au (0.94% CuEq), including 2.1m grading 0.10% Cu, 0.02% Zn, 141.0 g/t Ag and 1.76 g/t Au (1.77% CuEq) from TS-25-37w2

⦁ Tesla Zone Demonstrates Significant Scale and Remains Open. Drilling has now traced Tesla’s mineralized zone over 1.35 km along strike and up to 700 metres down dip, pointing to a large and vertically extensive system that remains open down-dip and along strike in both directions.

⦁ Summer drilling now underway. Two drills are active at Tesla — one targeting the down-dip expansion of the Lower Lens, and the other testing high-grade continuity in the northern Main Lens area.

⦁ Results expected to support maiden resource estimate. Mineralization intersected throughout the 2025 program are expected to positively contribute to the Company’s plans to prepare a first resource estimate for the Tesla Zone.

Erin Carswell, Foran’s Vice President, Exploration, commented: “With results from the final 15 drill holes returned from the Winter-Spring resource drilling program at the Tesla Zone, we have achieved excellent drill coverage and an even better understanding of the mineralization, its zonation and where significant potential remains to expand the zone in advance of a future maiden mineral resource estimate. In particular, we are seeing copper and gold grades within the Main and Lower Lenses increasing down-dip, and thick intervals of copper mineralization continuing towards the south of the target. Significant zinc and silver grades remain encouraging as always, and even the highest up-dip holes on the margin of the zone continue to intersect mineralization. A focused summer drill program is underway as we advance resource planning, with Tesla’s scale and consistency continuing to support the long-term potential for phased expansion opportunities at McIlvenna Bay.”

Drilling resumed at the Tesla Zone in late July, with two rigs now active. One drill is targeting the down-dip expansion potential of the Lower Tesla Zone, following up on the recently identified electromagnetic (“EM”) conductor plate that extends for approximately 650m along strike across the Lower Tesla Zone (see Foran’s June 17, 2025 news release). The second rig is testing the continuity of mineralization within the northern part of the Tesla Main Lens through a series of infill holes collared from the northeast shore of the lake.

2025 Winter Drill Program

Foran’s 2025 ice-based winter drill program consisted of approximately 28,494m of drilling completed at the Tesla and Bridge zones across 32 drillholes and wedges, along with approximately 3,941m of drilling focused on several regional targets near the McIlvenna Bay Deposit for a total of approximately 32,435m of drilling for the winter program.

To date, Foran’s drilling has defined multiple lenses of zinc-rich and/or copper-rich mineralization at the Tesla Zone and the 2025 drilling has expanded the zone to at least 1,350m along strike and 500-700m in the down dip direction. The winter program predominantly aimed to tighten up drill spacing across the Tesla and Bridge zones, utilizing wedging and directional drilling technologies to maintain the efficiency and precision of the drilling. These holes have significantly increased the confidence in the continuity of the mineralization across the Tesla and Bridge zones.

A plan map highlighting the locations of the final 15 drill holes from the program are provided in Figure 1 above, and a longitudinal view of the Tesla Main Lens is provided in Figure 2 below that demonstrates the locations of the new drill holes relative to prior drilling pierce points. Detailed descriptions of the newly released holes are provided in subsequent sections, along with a series of geological cross sections to put these new holes in context. A table of assay composites for the drill holes is provided in Table 1.
