Mineralization Comments

Jun 05, 2007 (Mark Puumala) - Brereton (1988) indicates that this occurrence is found within pyrite and tourmaline-mineralized quartz-filled fractures in diorite of the Bijou Point Complex intrusion. The occurrence is located immediately west of an approximately north-south-striking shear zone mapped by Brereton (1988). Brereton (1988) reported a grab sample assay of 520 ppb Au from this location (sample PBR-88-04).
