During the summer of 2022, C3 Metals made a discovery of an 8km by 4.5km area where over 100 rock chip samples have returned greater than 1% copper and up to 16.5% copper. Within the southeast portion of this mineralized footprint, a large-scale, epithermal vein swarm has been discovered. The vein swarm has been mapped over a 3km by 5km area and has return over 30 rock chip samples grading over 2.0 g/t gold and up to 58.1 g/t gold. Initial scout drilling confirmed both epithermal and porphyry style alteration and encountered anomalous gold and copper as well as pyrite, bornite and molybdenum. The Arthurs Seat mineral concession is located along the Crawle River Fault Zone and is contiguous and between C3 Metals' 50% joint venture Super Block and 100% owned Bellas Gate mineral concession.

Location Map


The project is underlain by andesitic volcanic rocks of Arthurs Seat. At surface, widespread copper mineralization occurs in fractures, shear zones and veins. Gold mineralization occurs in low-sulphidation epithermal veins.  Mineralization is accompanied by porphyry-style hydrothermal alteration and secondary copper oxides at surface. The wide extent of copper mineralization is confirmed by high anomalous copper in rock chip samples and regional scale geophysical anomalies.
