The Harvey, 3 kilometres southeast of Camborne, is likely the continuation of the Eclipse (082KNW044) vein. It was worked by the Harvey Bros. in 1900.
The vein, containing galena and pyrite, cuts metasediments of the Lower Paleozoic Lardeau Group.
Westmin Resources Ltd. sampled the adit in 1983. In 2019, Mariner Resources Corp. completed a 624 line-kilometre airborne magnetic and radiometric survey on the area as the Silver Dollar property.
