The Granite Creek Gypsum occurrence is on the east bank of Granite Creek, 3.5 kilometres southwest of the creek's confluence with the Tulameen River, and 14 kilometres west-northwest of Princeton.

A gypsum deposit is reported to have been traced along the east side of the Granite Creek valley for 800 metres, with an average width of 6 metres. A sample of light brownish gypsite (earthy gypsum) contained 31.48 per cent CaO, 44.32 per cent SO3 and 22.32 per cent H2O (Canada Bureau of Mines Report 245, page 103). This deposit is likely a precipitate of Recent age, similar to the Tulameen Gypsum showing (092HSE137). Well-rounded lumps of pure white gypsum are also found in the bed of Granite Creek.

This showing was prospected by H. Churchill between 1911 and 1913.
