Temagamite is a bright white palladium mercury telluride mineral with a hardness of 2½ on the Mohs scale. Its chemical formula is Pd3HgTe3. It was discovered at the Temagami Mine on Temagami Island, Lake Temagami in 1973,[3] and it represents a rare mineral in the Temagami Greenstone Belt.

It occurs as microscopic inclusions within massive chalcopyrite at Temagami in association with other rare tellurides: merenskyite, stützite, hessite and an unnamed Pd-Hg-Ag telluride.[4] In addition to the discovery locality, it has been reported from the Stillwater igneous complex in Montana and the New Rambler coppernickel mine in the Medicine Bow Mountains of Wyoming.[2]
