The Huron Prospect is the northeastern most prospect on a gold mineralized trend known at the Tooth Trend (J.R. Woodman, Senior Natural Resource Manager, Doyon Limited, written communication, 2014). The Huron prospect, Peak prospect, and Saddle occurrence are located on the Tooth trend, which coincides with projection of a southwest-northeast trending thrust fault contact, in Devonian sedimentary rocks (Wilson and others, 1998).

Huron gold mineralization is associated with (a) narrow quartz-sulfide veins within quartz monozonite sills and in sedimentary rocks adjacent to the sills; (b) semi-massive pyrrhotite-rich sulfide plus silica replacement bodies in calcareous sedimentary rocks adjacent to the sills. Quartz-sulfide veins contain up to 15 percent arsenopyrite and assays up to 1.4 grams of gold per tonne for a 5 foot interval (sample HC9603, 25 to 30 feet) with sericitic alteration selvages hosted in two quartz monzonite/granite dikes and adjacent sedimentary rock (ASA -Montague, 1997).

Sixty-one soil samples were collected on and near two quartz monozonite sills by ASA-Montague in 1994. Nineteen of the soil samples yielded assays of greater than 0.5 part per million (ppm) gold, with the highest containing 1.57 ppm gold (ASA-Montague, 1994a, 1994b). In 1996 and 1997, eleven core holes totaling 2,368 feet were drilled in sedimentary hornfels adjacent to the sills. A total of 10 drill intercepts ranging from 0.1 foot to 5.0 feet thick yielded assays of greater than 1.0 ppm gold (ASA-Montague, 1997).
