Significant by-product gold was produced at the Tilt Cove and Rambler Mines. The Rambler Mine, hosted by the Pacquet Harbour Group, consisted of several massive sulphide lenses (including the Ming, Ming West and Main deposits) hosted by felsic and mafic volcanic rocks and stringer sulphide bodies (East Mine and Big Rambler Pond) hosted by mafic volcanics. The volcanogenic sulphide bodies have stockwork (feeder) and stratiform zones, the latter having a conformable relationship with enveloping lenses of chlorite and quartz-chlorite-sericite schists considered to be metamorphosed equivalents of primary hydrothermal alteration haloes accompanying sulphide deposition on the sea floor. Although gold has been mined as a by-product of the VMS deposits of the Baie Verte area, its recognition in “gold only” epigenetic veins and replacement type occurrences was first widely noted in the mid-1980s. Gold occurrences were found to be widespread throughout the ophiolitic and island arc sequences, as structurally-controlled, and in association with, quartz and/or iron carbonate veins, silicification and/or breccia zones and shear zones, often accompanied by hydrothermal chlorite and sericite alteration. Pyrite is usually found as the most common and abundant sulphide. Other sulphides include chalcopyrite, pyrrhotite, sphalerite and galena. Gold commonly occurs as free particles in the quartz or as fracture and/or lattice intergrowths within pyrite crystals. This style of gold mineralization and emplacement are similar to the California “Mother Lode Type” gold deposits (Dearin and Christie, 1986) although no true “mother lode type” deposits have been located on the peninsula. According to Evans et al (1998), the Baie Verte peninsula is host to approximately 125 epigenetic, structurally controlled, gold occurrences which cluster along the major, regionally extensive, structural breaks such as the Baie Verte Line and are concentrated in the Cambrian- Ordovician ophiolitic rocks and their cover sequences
