Cameronite is a rare mineral that has been found to date (July 2023) only at the type locality.

Localities

The type locality is the Good Hope Mine, Vulcan, Vulcan Mining District, Gunnison county, Colorado, USA. Cameronite is a rare constituent of three museum specimens of tellurium-bearing ore from this hydrothermal deposit. Associated metallic minerals are native tellurium, rickardite, vulcanite, arsenopyrite and pyrite. Masses of cameronite up to 2 mm by 2 mm are known. Individual grains are anhedral, equidimensional and average about 200 microns in diameter (CM 24.379-384).
