Summary:

Rosemont gold deposit is hosted in a quartz dolerite zone of a dolerite sill intruding ultramafic and argillaceous sedimentary units of the western limb of the Erlistoun Syncline in the Duketon Greenstone Belt.

Gold mineralisation is associated with brittle fracturing and quartz albite sericite carbonate sulphide alteration within the quartz dolerite. Most gold occurs below the weathered profile in saprock and fresh rock with the upper saprolite being leached of gold.

The mineralisation trends NNW over a strike length of 4.9km and dips steeply to the east and west, varying along strike.

The geology at Rosemont has gold hosted in a steeply dipping quartz-dolerite unit intruding into a mafic-ultramafic sequence. Gold mineralisation is within a brittle quartz-dolerite phase of the Rosemont Dolerite, primarily occurring within discrete, steeply dipping, quartz-dolerite paralleled, en-echelon and stacked vein structures. The quartz-dolerite varies from 5 metres, up to 100 metres wide.
