Deposit Types
The Eastern properties, Stock, and Western properties are all located proximal to a 200 km central segment of the PDDZ which has generated approximately 100 Moz of gold since 1910. Over a hundred gold deposits are distributed along this major, compressional to transextensional, crustal-scale fault zone. Studies suggest a long-lived, multi-staged open/close orogenic system resulting in the emplacement of auriferous quartz-carbonate veins - a major component of the greenstone deposit clan (Dubé and Gosselin, 2007).
At the Black Fox and Froome mines, Stock and Western properties, gold-bearing veins are predominantly associated with:
• Structurally controlled dilatant zones (shearing, brecciation, offsets)
• Greenschist facies metavolcanic host rocks
• Crustal scale faults (i.e., the PDDZ)
• Syn-tectonic intrusive bodies
These characteristics are consistently seen at the Western properties, Stock and Froome sites and are classified as orogenic gold occurrences related to longitudinal shear zones. These greenstone-hosted quartz-carbonate vein deposits are a sub-type of lode-gold deposits (Poulsen et al., 2000) and correspond to structurally controlled, complex epigenetic deposits hosted in deformed metamorphosed terranes (Dubé and Gosselin, 2007).
Gold mineralization at the Grey Fox deposit (located 4 km to the southeast of the Black Fox Mine), is spatially associated with syenite, melanosyenite and quartz ........
