Summary:

The Taronga tin deposit is hosted in Permian-Triassic hornfelsed sedimentary and volcanic rocks of the New England fold belt, assigned locally to the Grampians Formation. The host rocks were folded about their northwest to southeast (true bearings) axes with subsequent orthogonal re-folding. The host rocks were intruded by granites of Permian-Triassic age and these granites were the source of the tin, copper and silver mineralisation at Taronga. This is a classical geological setting for hydrothermal tin deposits of Eastern Australia.

Geological mapping indicates that the Taronga mineralisation occurs in sheeted quartz vein swarms within a north-east aligned anticlinal structure. Tin occurs within the swarms of quartz veinlets and tin mineralisation has been defined within two large zones, known as the Northern and Southern Zones. Two vein swarms in the Northern Zone are between 10m and 80m wide over lengths of between 600m and 650m to a depth of approximately 200m. Four separate vein swarms in the Southern Zone are 8m and 10m wide over lengths of between 150m and 550m, and have been outlined by previous drilling to a depth of approximately 150m.

Mineralogical studies as part of the metallurgical investigations for the deposit recognised three sequential events at varying mineralisation temperatures ranging from hightemperature, through intermediate temperature to low temperature with pneumatolytic hydrothermal and epithermal styles, respectively. The primary tin mineral cassiterite (SnO2) occurs with all three events and the greisen alteration occurs in the first two events.

As well as cassiterite, the Taronga deposit contains small concentrations of copper and silver as well as other elements including tungsten, molybdenum and fluorine.
