Small quantities of hessite, associated with argentite and other minerals, were
found in the Griffith mine near Georgetown (Spurr and Garrey, 1908). An analysis

Geological Survey Professional Paper
Sindeeva (1964) observed that tellurium forms its own minerals in many diverse
types of ore deposits. In lead-zinc deposits she reported that tellurium
concentrates in galena in microscopic segregations of altaite (PbTe) and hessite
(AgTe).
