Dec 07, 2005 (B Nelson) - The occurrence, classed as a 'calc-alkalic porphyry' deposit type, is described by Carter (1981c): During the current (1980) survey, a mineralized portion of a thirty foot (9.14 metre) wide diabase dyke trending east northeast was located at Worthington Bay, in Lake Superior in the southwestern corner. The country rocks are syenitic to dioritic phases of the granitic Terrace Bay Batholith. There is no record or evidence of previous exploration and the deposit thus constitutes a new occurrence. McLeod (1984) sampled a quartz vein in this locality which was traced for 23 m and varied from 7.5 cm to 30 cm in width. The quartz vein fills a shear zone in the granite.

Dec 07, 2005 (B Nelson) - Grab samples of quartz vein collected by McLeod (1984) assayed up to 0.005 oz/ton Au and 0.53 oz/ton Ag.
Jul 16, 2018 (Therese Pettigrew) - A grab sample collected by M. Carter’s mapping crew assayed 2.76 opt Ag and 1.09% Cu (Carter, 1981). The showing consists of an irregular mineralized zone of massive pyrite, chalcopyrite and secondary malachite in a 9 m wide diabase dyke striking N80E intruding pink coarse-grained hornblende syenite. A grab sample of this mineralized material was assayed by the Geoscience Laboratories, Ontario Geological Survey and yielded <.01 ounce gold per ton, 2.76 ounce silver per ton, 1.09% copper, 36 ppm nickel and 14 ppm cobalt (Carter, 1988).
