The Fish Gold Mine is a remote locality in the north-east section of the Menzies Shire. It is 85 kilometres south-east of Laverton, the best and probably only access route. To reach is via the Burtville gold locality, then continue along the road south-east. Technically the area is called Irwin Hills, with Jasper Hill, part of the Irwin Range. The mining company however calls the area Jasper Hills.
The Fish mine/prospect is part of a small belt of ultramafics, pyroclastics and sedimentary rock, surrounded by granite. The greenstone sequence is part of the east facing limb of the Elore Anticline.
At Fish there is a north-south trending silica rich banded iron formation, within the mafic volcanic sequence. Gold is found near the Hanging Wall. North-west trending faults displace the banded iron formation progressively to the south. Numerous granite dykes and sills cut the greenstone sequence.
The auriferous quartz veining is associated with siderite, epidote, sericite or mica alteration assemblage. Sulphides at the lower levels is dominated by pyrite, pyrrhotite and chalcopyrite. The veins are surrounded by a siderite-magnetite alteration halo.
Exploration was conducted by Focus Minerals Limited.
Google satellite images provide an interesting optical illusion or aberration in that at a distance there appears to be a small open pit, while close up shows only exploration work. On the ground confirmation needed.
