Base Metals

The NANA region is located in a geological setting that hosts some of the largest and richest base metal deposits on the globe.

The Red Dog Mine is currently the flagship mining operation of a large zinc-lead district that includes no fewer than seven additional major mineral deposits.

The tectonic history of the Western Brooks Range produced another major mineral district that is marked by an 80-mile-long trend of volcanogenic massive sulfide (VMS) deposits that occur along the southern slope of the Brooks Range from north of Ambler east to the Beaver River.  The largest known deposit in this district is the Arctic copper-zinc-silver-gold deposit immediately north of Kobuk.

The Ambler Mining District is a world class site for VMS deposits that contain copper, lead, zinc, silver and gold. The Arctic deposit (NovaGold) ranks among the largest and richest VMS deposits in the world, with a resource of approximately 36 million tons of 4% copper, 5.5% zinc, 0.8% lead, 0.7 g/t gold and 54.9 g/t silver. The claims border NANA land near the Koguluktuk River.

One of the most advanced properties in the region on NANA land is the Bornite (also known as Ruby Creek) copper deposit near Kobuk and Shungnak. Bornite is a large underexplored copper deposit with a resource estimate of 71.6 MT grading 1.2 percent copper (Kennecott, 1977). The deposit also contains zinc, cobalt and germanium.

Bornite is a significant resource of copper and possibly zinc.  Additionally, numerous occurrences of base minerals, which are only prospects at this time, are known to occur throughout the region.
