The Kensington underground gold mine and associated milling facilities are located on the east side of the Lynn Canal about 45 miles north-northwest of Juneau, Alaska. The Company controls 100% of the mine through Coeur Alaska. The mine is accessed by a horizontal tunnel and utilizes conventional and mechanized underground mining methods. Ore is processed in a flotation mill that produces a concentrate that is sold to third party smelters.

Geology and Exploration Potential
The Kensington ore deposit consists of multiple, gold-bearing mesothermal, quartz, carbonate and pyrite veins and discrete quartz-pyrite veins hosted in Cretaceous-aged Jualin diorite. Gold occurs as native grains in quartz veins and is associated with pyrite and various gold-telluride-minerals associated with the pyrite mineralization.
The mine area consists of two contiguous properties, Kensington and Jualin, which constitute the majority of the Berners Bay Mining District. The Kensington property includes the Kensington and Raven mineral deposits, which contain all the mineral resources and reserves currently defined, as well as other gold occurrences such as Eureka and Elmira. The adjacent Jualin property includes the Jualin, Comet, Kimberly and other mineral occurrences. Both Kensington and Jualin properties are held through a combination of state and federal patented and unpatented lode mining claims either owned directly or under lease. All of the defined mineral resources and reserves are contained in the Kensington block.
Exploration in 2015 totaled $4.0M at Kensington and resulted in an initial resource estimate at the Jualin deposit, which was disclosed in a preliminary economic assessment in April 2015. 2016 exploration will focus on underground drilling at Jualin Vein #4 to further define and expand mineralization, as well deeper portions of the Kensington ore body and the high-grade Raven zone.
