The Copper Belle zone shows a Gold-Molybdenum porphyry style of mineralization. The alteration zones are related to airborne EM high anomalies surrounded by airborne magnetic high anomalous zones towards the southwest.
The Copper Belle zone is a stockwork and disseminated gold-molybdenum porphyry mineralization in outcrop that was recently exposed due to rapid glacial melting. It is the northeast extension of the historical Goat Trail zone (0.61 g/t Gold over 40.5m, 0.65 g/t Gold over 41.3m) in the West Nunatak zone in the Treaty Creek property. The adjacent area (Konkin Zone) has historic high-grades including a trench sample taken in 1987 with 969 g/t gold over 1.2 meters possibly associated to a skarn zone.
Gold mineralization in the Copper Belle zone is associated to a strong potassic alteration of the Lower Jurassic rocks of the Hazelton Group, mainly andesitic breccias, flows and tuffs with minor interstratified feldspathic sandstones, showing conspicuous veining and stockworks. A later sericite-carbonate-quartz-pyrite alteration overprints the potassic altered zone and surface alteration produces a characteristic oxidation of the exposed rocks. Molybdenum-gold rich zones have been found in drill-core associated to a potassic alteration of a monzonitic intrusion. Stockwork and disseminated gold-molybdenum porphyry is the style of mineralization in the area.
The type and age of the host rock, the style and age of the mineralization, as well as the alteration and the gold grades found in drill-core is similar to those found in the nearby Mitchell and Snowfield deposits.
