The Keno Hill Silver Camp is Canada’s second largest historical primary silver producer. The camp saw production from approximately 35 vein deposits between 1913 and 1989 producing over 217 million ounces of Silver. Alexco Resources Corp. is currently in the process of placing the Keno Hills Silver Camp into production.

Exploration on the Inca Property began in 1974 where grid soil sampling and bulldozer trenching located more than 10 galenabearing veins containing massive to semi-massive galena with high silver to lead ratios. The best exposures were discovered in Zone 12 where a 0.3 to 1.0 m wide lens of massive galena assaying 3,774 g/t silver was exposed in a northeast-trending fault for a length of over 40 metres. The property changed hands in 1983 and from 1983 – 1986 Dawson Eldorado Mines Ltd. extracted 1125 tonnes of ore from surface producing 188,000 ounces of Silver.

The Inca property is within the Tintina gold belt and shows a number of geological similarities to the Keno Hill Silver camp located approximately 180 km west. The mineralization occurs in a series of sub parallel high angle fissure veins; in a shallow dipping vein developed within a thrust zone. Typically the veins are steeply dipping, narrow, tabular or splayed. Commonly these veins occur as sets of parallel and offset veins. Individual veins vary from centimetres up to more than 3 metres in stockwork zones. The Keno Hill area is historically known to host some of the largest polymetallic vein deposits in Canada.
