Aug 27, 2014 (A Wilson) - The known mineralization occurs as zones of gold-bearing vein quartz in sheared, pyritized tonalite-trondhjemite. The Hutchinson Vein is underlain by gneissic trondhjemite-tonalite.

Aug 27, 2014 (A Wilson) - Grab samples collected in 1946 returned assays ranging from 0.02 oz/t Au over 2 feet of 0.72 oz/t Au over 1.7 feet. The best assays from the diamond drilling completed by Coniagas returned 0.055 oz/t Au over 11.8 ft; 0.047 oz/t Au over 6.3 ft, 0.03 oz/t Au over 3.1 ft. A rough estimate of the grade of the vein is 0.20 oz/t Au over 10 ft. Grab samples of another quartz vein approximately 400 ft NE of the main vein averaged assays of 0.04 oz/t Au over 5 feet.

Geologist: A Wilson
Notes: The showing consists of three occurrences of gold-bearing quartz veins. The quartz occurs as veins and lenses within zones of fracturing in the tonalite-trondhjemite. The Mickelson-Hutchinson has been interpreted to be a lenticular-shaped quartz-filled fracture zone trending ENE, dipping, NNW and plunging N30E. The widest and longest part of the lens probably occurs at a depth of 50 ft below surface.
