Sulphurets Creek, and its tributaries, drains an area underlain by Lower Jurassic Unuk River Formation rock, Hazelton Group. Gold colours, flakes and nuggets have been found in the gravels and al- luvium along the lower reaches of the creek from near Ted Morris Creek downstream to the confluence with the Unuk River. Placer gold production from 1936 to 1940 was reported at 809 grams (Bulletin 28). A Sauerman dragline with a 1/4 yard bucket was utilized in the sluicing of about 274 metres of gravel near the mouth of Mitchell Creek. Gold recovery was not reported (Geology, Exploration and Mining, 1974-361).
Coarse boulders and swift waters along the remote location and long winters have restricted work on this placer occurrence.
