The Sir John Gold Mine is 2 kilometres north-east of the Kalgoorlie city centre. It is a shallow modern pit accessing regolith hosted gold. The Mystery, Mount Percy and Union Club pits are virtually co-joined to it. Geology information can be found under the Mystery and Mount Percy Mindat headings. There was also in the 1890's, a Hannans Sir John Forrest mine but this is a different location on the Golden Mile.
By 1932, it was reported the mine had produced 593 tonnes of ore for 113 ounces of gold.
