Mapping completed by TerraX during 2014-2019 has built on the historic mapping in the Kam and Banting Group’s. This work has further outlined gold mineralization hosted in the Banting Group, which hosts the Sam Otto style, and Kam Group, which is host to the Giant, Con and Campbell shear zone styles.
The Sam Otto style mineralization has been defined for about 2.5 kilometres along the five (5) kilometer Sam Otto north-south trending (ie. 000 to 005/75) structural corridor. Within this corridor there are 100 to 200 metre wide, moderate to strongly developed shear zones hosted within an intermediate crystal tuff. Locally higher-grade lenses occur which are at a 10 to 15 degree angle to the main north-south shear. Alteration changes from distal biotite-chlorite to proximal silica and sericite associated with the gold mineralization. Sulphide mineralization (ie. pyrite, pyrrhotite and arsenopyrite) associated with the gold appears to be related to the sulphidization of very fine-grained primary magnetite that is spatially associated with biotite-chlorite aggregates. This feature is best defined by changes in magnetic susceptibility with changes from >1.0x10-3 SI units in unmineralizaed zones to typically 0.1x10-3 to 0.6x10-3 SI units in gold bearing zones. The highest-grade gold mineralization is associated with well-developed silica–sericite alteration, acicular arsenopyrite, fine grained pyrite/pyrrhotite and S2 parallel (010-015/80) quartz veins.
The 2019 mapping on the extension of the Giant mine geology outlined a folded and strongly sheared and altered package of mafic flows, intermediate to felsic tuffs, porphyry dikes and gabbro dikes and sills. In addition, the Bode fragmental unit was outlined 250 to 500 metres west of the Jackson Lake Formation unconformity. This suggests a structural and stratigraphic setting similar to that of the Campbell Shear.
