Abstract
The Gooseberry vein is a precious-metal, epithermal, calcite-quartz vein deposited in Tertiary volcanics along the east-west trending Gooseberry fault. Propylitized rocks envelop this fault and the north-northeast trending Red Top structures. The alteration pattern suggests that the Red Top structures may contain precious-metal mineralization at depth. Ore-shoot location is controlled by abrupt change in dip, major change in strike, and intersection with northeast-trending faults. The silver-to-gold ratio increases markedly with depth. Preliminary fluid-inclusion studies indicate a temperature of deposition between 240 and 245°C, probably under non-boiling conditions and hydrostatic pressure.
