Locality type:


A nickel mine located about 12 km SSE of Widgiemooltha.
Started in 2001.

The miitel deposit was discovered in the early 1970's by Union Miniere and Anaconda Resources, but due to a poor understanding of the local geology the resource was not examined in detail. Western Mining Corporation subsequently partially developed the mine which was taken over by Mincor Resources in 2001. They further discovered orebodies both north and south of the main deposit. The mine is named after David Miitel, the driller who found the ore.

To 2012, Mincor states is has mined from the deposit 2.03 million tonnes of ore at 3.01 Ni from 61 000 tonnes of nickel ore.

The main orebody is elongated, boomerang shaped plunging north and south with a channel structure hosting the ore lense. It sits on the eastern flank of the Widgiemooltha Dome. The ore is highly strained massive to matrix olivine-sulphide adcumulate , with a fine pyrrhotite-pyrite groundmass and prominent pentlandite porphyroblasts. The komatiite is dominated by talc-magnesite-amphibolite assemblages with accessory nickeline, gersdorrffite, millerite and chromite.
