Cassiar Gold Files Updated Technical Report and Expands 2025 Drilling Programme

• Filed NI 43-101 technical report shows 410,000 ounces indicated and 1.93 million ounces inferred gold resources at Taurus deposit
• Expanded 2025 drilling programme to 7,000 metres from initial 5,000 metres, with 5,211 metres completed across 15 holes
• 91% of mineral resources occur within 150 metres of surface at the pit-constrained Taurus deposit
• Newcoast target drilling encounters similar geology to Taurus deposit across 4-kilometre strike length
• Management scheduled for six mining conferences from September 2025 through March 2026

Cassiar Gold Corp. (TSXV: GLDC) (OTCQX: CGLCF) is a Canadian gold exploration company with a 100% interest in the 590 square kilometre Cassiar Gold Property in northern British Columbia. The property consists of two project areas: Cassiar North, which contains the Taurus deposit, and Cassiar South, which hosts historical workings and exploration prospects.

The company also holds properties in the Sheep Creek gold camp near Salmo, British Columbia. Historical records indicate the Sheep Creek district produced 742,000 ounces of gold at an average grade of 14.7 grams per tonne between 1900 and 1951.

NI 43-101 Technical Report Filing & Updated Mineral Resource Estimate

The company filed an independent technical report dated June 8, 2025, authored by qualified persons Scott Zelligan and Chantal Jolette. The report outlines mineral resources at a 0.4 grams per tonne gold cutoff using a $2,400 per ounce gold price. Indicated resources total 8.8 million tonnes at 1.43 grams per tonne gold for 410,000 ounces.

Inferred resources comprise 63.2 million tonnes at 0.95 grams per tonne gold for 1.93 million ounces. The resource model extends from surface to a maximum pit depth of 307 metres. The technical report identifies areas of mineralisation beyond the current pit shell model with gaps in drill data between mineralised zones.

According to CEO Marco Roque,

"The new MRE outlines an expanded, robust, near-surface, pit-constrained asset with great access."

2025 Exploration Campaign Progress

The 2025 drilling programme began on June 20 and continues at the Newcoast target in the Cassiar North project area. The programme scope increased to approximately 7,000 metres over 20 drill holes from the initial 5,000-metre plan. As of the announcement date, 5,211 metres have been completed across 15 drill holes.

At the Taurus deposit, nine holes totalling 2,080 metres focused on lateral expansion drilling. The step-out holes target areas beyond the known mineralised footprint to test resource continuity. At the Newcoast target, six holes totalling 3,131 metres have been completed, including the deepest hole drilled to date at 720 metres.

Previous drilling at Newcoast in 2023 and 2024 returned 141.4 metres of 0.89 grams per tonne gold from 143.1 metres downhole. Current drilling aims to test continuity of this mineralisation and evaluate induced polarisation anomalies identified in 2024 surveys. Visual observations include quartz veining and sulphide mineralisation in altered volcanic host rocks.

Corporate Activities & Governance

The company has scheduled conference participation through March 2026, including the Precious Metals Summit in Beaver Creek (September), Munich Mining Conference (October), New Orleans Investment Conference (November), Vancouver Resource Investment Conference (January), AME Roundup (January), and PDAC in Toronto (March).

On September 9, 2025, Cassiar Gold awarded 350,000 restricted share units to advisors under its RSU/DSU plan. Two-thirds of the units vest after 12 months and one-third after 24 months. Each vested unit converts to one common share at a price based on the September 8, 2025 closing price.

The combined stock option and RSU/DSU plans provide for awards of no more than 14,665,930 common shares. Jill Maxwell, P.Geo., serves as VP Exploration and qualified person for technical disclosure under NI 43-101 standards.

Conclusion and Next Steps

The 2025 drilling programme is expected to conclude in autumn with results pending for current holes. The expanded 7,000-metre campaign targets both resource expansion at Taurus and regional exploration at Newcoast. The filed technical report provides the current resource baseline for future development planning at the northern British Columbia property.
