Adam Travis, CEO comments: “Coast’s focus in 2025 was on expanding our generative pipeline and completing baseline studies for a discovery-focused 2026. Our portfolio now includes mineral tenures covering high-grade silver, copper, gold and rare earths, all located within some of the best mining districts in BC. In parallel, we increased our treasury by vending a non-core Toodoggone property and had no dilutive capital raising events during 2025. On behalf of Coast’s management team and Board, we’d like to thank all our shareholders for their loyalty and support in 2025. With the backdrop of the prices of key minerals in the Coast project portfolio at or near all-time highs, we look forward to continuing to advance our execution strategy in 20
