The Southern Group has seen the bulk of exploration to date and contains the majority of resources at this point in time, though it still has significant upside with many targets to test.
The Southern Group deposits all contain oxide mineralisation, though remain open at depth.
The depth of cover and regolith in the southern part of the Redcliffe Gold Project is similar to the Central area.
Extensive shallow historical exploration along the Mertondale Shear Zone (MSZ) by previous explorers in the 1990’s detected anomalous gold generally below a 30-40m zone of depletion, when drilling was deep enough. However, the majority of holes were completed to less than 50m depth, which led to the drilling missing many gold mineralised zones, subsequently identified by NTM.
The MSZ is 1-1.5km wide and shows orientation changes within the Greenstone Belt, prime structural locations for gold deposition. Along the Great Western Fault, the western bounding shear to the MSZ, gold deposits including GTS and Bindy have been discovered and are hosted within steeply dipping, tightly folded intermediate schist, felsic schist and black shale. Mineralisation occurs in sulphidic quartz-cherty silica veins with sericite-carbonate alteration.
The Kelly Deposit, adjacent to the Mertondale Fault (eastern bounding shear) is hosted within and proximal to sheared felsic porphyry and mafic schists. Depth of weathering at Kelly is 90m and mineralisation occurs as quartz-pyrite veinlets with associated ankerite-sericite silica alteration.
Several prospects showing geological similarities to known gold deposits along the Great Western and Mertondale Faults are priority targets and require further drilling, including Barry North, GTN, Jessie and MF1.
