Paterson area 1:250 000 scale solid geology interpretation and depth to basement model - explanatory notes

Created 16/10/2025

Updated 16/10/2025

An interpretation of the Paterson area has been carried out to understand the distribution of Proterozoic bedrock beneath thin (<300 m) Phanerozoic cover. Numerous granitic intrusions have been identified to the north of Telfer, which intrude a pre-deformed Neoproterozoic sequence, suggesting that this shallowly covered area is prospective for granite-related Au-Cu mineralisation. Neoproterozoic sedimentary rocks in the south of the area previously interpreted to be part of the Tarcunyah Group might instead be part of the Yeneena Basin. The absence of Neoproterozoic granites in this part of the area means that these rocks have a low potential for Au-Cu mineralisation, but have a relatively high potential for base metal and unconformity-style uranium mineralisation. Depth to Proterozoic basement modelling has also been carried out for the area, effectively mapping the depth of the surface represented by the solid geology interpretation. This has shown that much of the area has only a relatively thin cover (typically less than 300 m), making it accessible for exploration. In contrast, the Phanerozoic Waukarlycarly Embayment in the northwest of the area contains a relatively thick succession (with maximum depths exceeding 3000 m) within a NNW-trending, steep-sided graben that is 30-40 km wide.
