چکیده
base and precious metals associated with porphyry, epithermal and acid sulphate or high-snlphidation hydrothermal systems (Panteleyev, 1992; Panteleyev and Koyanagi, 1993, 1994). The majority of these systems are associated with the Early to Middle Jurassic Island Plutonic Suite and Early Jurassic B O M ~ Group rocks. The regional mapping component of this study focused primarily on potential ties between mineralization and key elements of the Bonanza volcanic stratigraphy. The preliminary findings reported here demonstrate a distinct and regionally persistent relationship between felsic horizons in the volcanic pile and acid sulphate alteration assemblages variably endowed in base and precious
