Amarc Confirms Discovery of Third New Porphyry Copper-Gold System at JOY
Discovery of Third Porphyry System Validates District Scale Potential While Financial Risks Persist

The news release dated February 19, 2026, confirms the discovery of a third porphyry copper-gold system, named TWINS, within the 100%-owned JOY District in British Columbia. This follows the previously announced AuRORA and CANYON discoveries. Key assay results from the 2025 program at TWINS include hole JP25106, which returned 300 meters of 0.51 g/t Au and 0.23% Cu (beginning at 819m depth), with a higher-grade sub-interval of 45 meters at 1.08 g/t Au and 0.47% Cu. The discovery is situated within a large 8.5 km² IP chargeability anomaly. The company also confirmed that $16 million was spent on the JOY District in 2025, fully funded by partner Freeport-McMoRan.
This news is materially positive as it transitions the JOY project from a single-deposit story (AuRORA) to a multi-deposit district-scale play. - Geological Validation: The discovery of TWINS validates the "lithocap exploration" model used by the technical team. The fact that mineralization was found beneath a large lithocap suggests other anomalies in the district may also host concealed porphyry systems. - Strategic Partner Commitment: Freeport-McMoRan has elected to proceed to Stage 2 of the Earn-In Agreement, committing an additional $75 million over five years to earn an extra 10% interest (total 70%). This secures long-term, non-dilutive funding for the flagship project. - Scale: The footprint of the JOY District (now three discoveries plus historical deposits like PINE and Brenda) suggests a Tier 1 potential similar to the Golden Triangle, though still at an early exploration stage.
Amarc Resources is a "Hunter Dickinson Inc." (HDI) company focused on developing district-scale copper-gold assets in British Columbia. - JOY District (Flagship): A 630 km² land package in the Toodoggone region. It is the northern extension of the Kemess porphyry district. It hosts the AuRORA, TWINS, and CANYON discoveries. - DUKE District: Located in central BC, currently under a 70% earn-in agreement with Boliden ($90M commitment). - IKE District: Located in south-central BC, 100% owned, hosting the IKE and Empress deposits.
