Cretaceous aged intrusives and gneissic and schistose country rocks host sugary textured quartz veins and local quartz vein stockworks. Historic rock grab and hand trench sampling by Avalon Development Corporation (“Avalon”) returned gold values from trace to 19.1 g/t Au, with gold occurring in association with elevated bismuth, tellurium, and arsenic.
In addition to the Maple Leaf prospect, two other prospects are currently known within the property and indicate the presence of a substantial fluid-rich mineralizing system: American Eagle and Tourmaline Ridge. The American Eagle prospect is located 5.6km northeast of Maple Leaf and consists of a 400 x 50m ridgetop cut by 5-10% sheeted white quartz veins with coarse grained bismuthenite. Limited historic grab sampling returned values from trace to 3.03 g/t Au, up to 3,880 ppm bismuth, up to 5,160 ppm arsenic, and up to 494 ppm molybdenum.
Tourmaline Ridge is located 2.4km west of Maple Leaf and consists of tourmaline-bearing paragneiss containing massive tourmalinite (> 50% tourmaline), with lesser quartz veins and tourmaline-vein breccias. Historic sampling of the tourmaline-rich rocks by Avalon returned weakly elevated gold values (maximum 164 ppb Au), up to 804 ppm bismuth, and up to 2,620 ppm arsenic. The intensity and extent of the tourmaline suggests high levels of fluid flow related to intrusive activity.
