Feb 24, 2010 (C Ravnaas) - The occurrence is situated within intermediate pyroclastics of the Upper Manitou Lake Group immediately northwest of the fold axis of the Manitou Anticline, and 2.4 km northwest of the Manitou Straits Fault. The Trafalgar Bay Zone Occurrence consists of a 12 m wide, northeast-trending shear/breccia zone extending for approximately 50 m through intermediate lapilli-tuff. The wall rocks are chloritic, intensely iron carbonatized, and contain <1-2% disseminated pyrite. A wide breccia zone consisting of angular, altered fragments of the wall rock embedded in a quartz carbonate-tourmaline matrix can be observed in the trenches. Quartz veins and stringers contain minor amounts of disseminated pyrite. Three old trenches and two test pits have been sunk on the shear/breccia zone. A grab sample, taken by the author, of the wall rock and quartz vein assayed 870 ppb gold while channel and grab samples, taken by St. Joe Canada Incorporated, assayed consistent low grade and anomalous gold values such as 0.10 ounce gold per ton across 1.0 m. (OGS OFR 5723, p. 290, 1989)

Feb 24, 2010 (C Ravnaas) - Best assay: 4.8 g/t Au over 1.0 m. A grab sample taken by OGS staff of the wall rock and quartz vein assayed 870 ppb gold while channel and grab samples, taken by St. Joe Canada Incorporated, assayed consistent low grade and anomalous gold values such as 0.10 ounce gold per ton across 1.0 m.
