Gold mineralization on the Property is associated with two principal styles of mineralization:

1. Narrow, high-grade gold-bearing quartz-carbonate veins hosted in metamorphosed mafic lavas (greenstone) and porphyry, which were the main source of gold produced at the Pickle Crow Mine from 1935 to 1966; and
   
   
2. Iron formation hosted gold mineralization adjacent to vein structures. The iron formation contains stringers and discontinuous lenses of quartz and the iron-bearing minerals have been replaced by sulphides.  Both quartz and sulphides are gold mineralized.  Only a limited amount of this type of material was processed at the Pickle Crow Mine.  However, iron formation hosted gold was the main ore type at the adjacent Central Patricia Mine.
