Cassiar Gold Reports High-Grade Visible Gold at Newcoast and Evaluates Mill Refurbishment Options

• Drill hole 25NC-017 returned 176.50 g/t Au over 0.3 metres within 15.7 metres grading 3.80 g/t Au at Newcoast East
• All eleven drill holes encountered mineralisation above 0.4 g/t Au, extending the mineralised zone over 4 kilometres
• Completed 2025 exploration programme totalling 7,308 metres across 20 diamond drill holes
• Commenced evaluation of mill refurbishment and tailings reprocessing at Cassiar South
• Metallurgical testing for Taurus deposit underway with results pending

Cassiar Gold Corp. (TSXV: GLDC) is a mineral acquisition and exploration company in Canada advancing its 590-square-kilometre Cassiar Gold Property in northern British Columbia. The property comprises Cassiar North, which hosts the Taurus deposit with Indicated Mineral Resources of 8.8 million tonnes at 1.43 g/t Au (410,000 ounces) and Inferred Mineral Resources of 63.2 million tonnes at 0.95 g/t Au (1.93 million ounces), and Cassiar South, which contains historical underground workings that produced over 315,000 ounces at head grades between 10 and 20 g/t Au. The company also holds properties in the Sheep Creek gold camp near Salmo, British Columbia.

Newcoast Prospect Drilling Results

The company reported results from eleven diamond drill holes totalling 5,243 metres at the Newcoast prospect, located 2 kilometres southeast of the Taurus deposit. All drill holes encountered mineralisation above 0.4 g/t Au, expanding a zone initially identified in 2023 drilling.

Drill hole 25NC-017 intersected 15.7 metres grading 3.80 g/t Au from 249.1 metres downhole, including 176.50 g/t Au over 0.3 metres. The hole tested chargeability anomalies identified in 2024 geophysical surveys and encountered quartz veins with visible gold in iron-carbonate-sericite altered basalt.

Other results include drill hole 25NC-019, which returned 22.5 metres of 3.52 g/t Au from 420.9 metres downhole, including 42.41 g/t Au over 1.6 metres, and drill hole 25NC-010, which delivered 89.2 metres grading 0.71 g/t Au from 217.3 metres downhole. The mineralised trend now extends over 4 kilometres in east-west direction.

2025 Exploration Programme Completion

The 2025 drilling campaign totalled 7,308 metres across 20 diamond drill holes and concluded in early October. The programme tested expansion potential at Newcoast and evaluated geophysical targets from 2024 induced polarisation surveys.

Drill hole 25NC-013 encountered 167.5 metres grading 0.42 g/t Au from 499.4 metres downhole, representing the deepest mineralisation encountered at Newcoast to date. The drilling programme filled gaps in previous coverage and extended known zones laterally and at depth.

The technical team documented visible gold in multiple holes and broad intercepts averaging above 0.4 g/t Au across all drill holes. The company is integrating 2025 results into planning for the 2026 field season, which will include exploration drilling and field investigations.

Mill Refurbishment and Tailings Evaluation

Cassiar Gold initiated an assessment programme evaluating refurbishment of an existing permitted milling facility at Cassiar South and metallurgical testing of historical tailings. The evaluation includes unmined high-grade mineralisation from past-producing underground operations.

The Cassiar South area contains small-scale vein systems where past-producing mines ceased operations decades ago. The company is evaluating previous metallurgical testing programmes on the historical tailings management facility to support further testing for gold recovery.

Marco Roque, President and Chief Executive Officer, stated:

"From a business perspective, as we continue to advance our priority exploration targets, we are looking forward to broadening our focus in 2026 to highlight our project's unique advantages amid record gold prices, including established infrastructure and valuable optionality from past-producing high-grade mines."

Next Steps

Cassiar Gold's priorities include integrating 2025 drilling results into the 2026 exploration programme, completing metallurgical testing for the Taurus deposit, and advancing mill refurbishment and tailings monetisation evaluations at Cassiar South. The technical team is planning field investigations and drill targeting whilst assessing additional opportunities across the property.
