Abandoned gold mine, worked from 1994 to 1996.
The Jupiter Gold Mine is 40 kilometres south-west of Laverton, and just north of the Lake Carey salt-pan, in a marginal salt-bush and lake sediment zone bordering the salt-pan.
The mine consists of two pits called Joanne and Jenny, immediately adjacent to each other. The northern pit is larger, and 90 metres deeper. Both have been commonly called Jupiter, and in recent times Doublejay. Several prospects exist within 2 kilometres north and south of the pits. It was decided the easiest solution was to keep the pits under the one heading, listing the various names, which is what the mining and exploration companies have done to this point. Then list the prospects under this.
The pits are spectacular, showing a complex maze of syenite and feldspar porphyry intrusions in basalt. The present exploration company (Dacian)is making strong noises of re-opening the mine as a larger open pit, so this sight may not last.
The pits were developed by Dominion Mining across 1994 to 1996. In September 2015, a JORC Indicated resource was announced for Jupiter of 13 Mt @ 1.4 g/t yielding 605 000 ounces of gold, and an Inferred resource of 13.48 Mt @ 1.1 g/t yielding 480 000 ounces. Approximately 150 000 ounces of gold was obtained during the two year mining period .
The mine is found in the 2 kilometres north-south Jupiter Corridor.
The Jupiter deposit is hosted in greenschist facies metamorphosed tholeiitic basalt, quartz-alkali feldspar syenite, and quartz feldspar porphyry. The syenite intrudes the basalt as irregular shaped dykes radiating from a larger stock, and at least three east-west and north-east to south-west quartz-feldspar porphries that intrude both the syenite and basalt.
Brittle-ductile shear zones are shallow dipping or steep dipping to the south and west, north-west and north-east striking. The primary contributor to the deposition of gold is the north-south trending, shallow east dipping, Cornwall Shear Zone.
Quartz-carbonate veins that host the gold occur in all lithologies and form three types: 1) veins restricted to shear zones 2) discrete veins sub-parallel to the shear zone hosted veins 3) stockwork veins forming networks of randomly orientated microfractures in syenite proximal to the shallow dipping shear zones.
Gold bearing veins consist of quartz, calcite, ankerite, and albite, with minor sericite, pyrite, chalcopyrite, galena, sphalerite, molybdenite, telluride minerals, and gold. Proximal hydrothermal alteration zones to these veins consist of quartz, calcite, ankerite, albite and sericite. High grade gold is mainly found in the syenite, and Hanging Walls to the shallow dipping shear zones in syenite.
The Jupiter deposit is a stacked lode, resembling the Wallaby mine, 8 kilometres to the east, both unusual for gold being associated with syenite intrusions.
