Gold rich sulphide replacement ore and vertically dipping gold-bearing quartz veins have been worked on Island Mountain since the 1870s. Island Mountain is located immediately northwest of the Jack of Clubs Lake and just west of the town of Wells.
Island Mountain operated from 1934 to 1967, exploiting both vertically dipping quartz vein and replacement-style mineralization for a total reported production of 603,800 ounces of gold with an average grade of 0.45 ounces per tonne. Both Aurum and Mosquito Creek Mines focused on replacement style mineralization due to its higher grade and more coherent geometries. The mine closed in 1966 due to low metal prices.
The Aurum Mine, located at Island Mountain was developed on 11 levels to a vertical depth of ~300m via an internal shaft. Further development of the mine to the northwest was limited due to the historic boundary with the Mosquito Creek claim group, now owned by BGM. A later owner of the Aurum Mine developed extensions of the Island Mountain Mine into the Mosquito Creek claim group at a depth known as the Aurum Mine. Five levels were developed at Mosquito Creek over a strike length of over 1,000 feet between two prominent structures, the Burnett and Mosquito faults. The current drilling phase targets both fine-grained pyrite replacement and quartz vein styles of gold mineralization in large unexploited areas adjacent to past-producing gold mines.
Island Mountain also hosts the Mosquito Creek Gold Mine, a small historic mine located 750 feet above the upper workings of the Aurum Mine. The mine was developed by Mosquito Creek Gold Mines Ltd. and operated from 1980 to 1987 producing 23,000 oz of gold. Again, the Company focused on replacement mineralization, leaving behind most of the vertically dipping quartz vein ore.
Underground development included a vertical shaft to a depth of 516 feet and levels at elevations of 4,400, 4,300, 4,200, and 4,100 feet. Following this early work by Mosquito Creek Gold Mines, a number of joint ventures saw additional underground development and exploration work carried out on the property.
