• CALAVERITE (Gold Telluride)

    Calaverite is one of the few minerals that is an ore of gold besides native gold itself. It is the most common gold bearing mineral besides native gold. The element gold is typically either found as native gold (in its elemental state) as an alloy with other metals such as silver and copper and as trace amounts in a few minerals.

    Tellurium was discovered in 1783 by Franz Joseph Müller von Reichenstein at Sibiu Romania.

Preliminary investigation showed neither antimony nor bismuth to be present.
