Exploration Potential

Volcanogenic massive sulfide (VMS) mineralization occurs in a series of polymetallic deposits along the entire 70-mile (100-kilometer) strike length of this belt.

Adjacent to the Company’s land holdings, which encompass the Arctic deposit as well as number of polymetallic (precious and base metals) VMS prospects, are two VMS deposits: the Sun deposit owned by Valhalla Mining LLC and the Smucker deposit owned by Teck Resources Ltd.

So far exploration work in the Ambler Schist Belt has outlined three major deposits (Arctic, Smucker and Sun) as well as 30 prospects. Ten of those prospects have been drill tested and have encountered mineralization:

BT/Jerry Creek Nora South Cliff
Bud Shungnak Sunshine
Dead Horse Snow West Shungnak
Horse-Cliff    

Hydrothermal dolomitization and copper-cobalt mineralization occur across the entire width of outcropping carbonates.

The Bornite Carbonate Sequence, host to the mineralization at Bornite, is exposed over approximately 10 miles (16 kilometers) along the north slope and southern margin of the Cosmos arch. Most notable of the known prospects are the Pardner Hill and Aurora Mountain areas, where outcropping mineralization was discovered and drill-tested during the Kennecott era.
