The discovery of the Red Star area was initially announced by the Company in October of 2024 when it was discovered during a drill program targeting H-Vein extensions. Additional drilling targeting the Red Star area has yielded results similar to those previously released in 2024 and 2025, where discrete high-grade intervals show up within wider zones of mineralization. Since the discovery of the Red Star area, the Company has made its delineation a priority given the proximity to the Company's current operations and existing infrastructure.
