- Type
- Sediment-hosted disseminated gold (Carlin type)
Disseminated gold deposits about 7 km north of the Bingham Canyon porphyry, in brecciated, clay-altered quartzites and limestones; the most scattered ε205Tl ever observed in a hydrothermal system (-16.4 to +6.0), anomalies linked to Tl-Sb-As-enriched breccias and low-temperature fluids according to Fitzpayne et al. (2018). Indicative coordinates, derived from the distance to Bingham Canyon.
