The Darlot lodes are considered to be part of an Archean hydrothermal fault-vein deposit with many similar characteristics with other deposits within the Yilgarn Craton, namely host rock type and nature of hydrothermal alteration; however, it is atypical in being relatively flat-lying rather than steeply dipping. Felsic porphyries and lamprophyre intrusions are encountered throughout the deposit. The major host for gold mineralisation is the Mount Pickering Dolerite. Gold mineralisation is associated with quartz veins and alteration haloes controlled by major D2 and D3 structures or secondary splays and cross-linking structures. The quartz veins are hosted mainly by magnetic dolerite and magnetic quartz dolerite rock types and, to a lesser extent, by non-magnetic dolerite and felsic volcano sedimentary rock types. Lamprophyre intrusions are present in the area with a variety of orientations. In most cases the lamprophyres are thought to be pre-mineralisation but are an un-favourable host rock for mineralisation and in most cases are barren. Mineralisation is hosted by a fractionated Dolerite sill within the greater Mt Pickering dolerite syncline, with silica+/-albite+/- carbonate+/-pyrite+/-gold being the key alteration components. St George is part of the Darlot Gold Mine, and the interpretation is based largely on the Centenary style mineralisation that is also in part associated with the Oval and Burswood Faults, with minimal supergene enrichment. St George Mineral Resource has not been mined due to unfavourable economics in the past, however an economic review is still to be completed. In the St George area, the mineralisation crosses lithological boundaries and is present in the mixed basalt, dolerite and felsic porphyry (MD and FAP) domains. The St George gold mineralisation is located about the Oval and Burswood Faults and is associated with quartz veins and alteration haloes controlled by major D2 and D3 structures, secondary splays and cross-linking structures such as the echelon tension gash arrays as a result of oblique reverse movement on the faults stated above.
