The Cochenour-Willans Mine was in production for thirty-two years between 1939 and 1971. Over that period, ~2.31 million tonnes of ore was processed with ~1.24 million ounces Au being recovered at a grade of 0.538 oz/ton. Underground mine workings extended down to the 2200 foot level and the mill capacity was 150-200 tonnes per day (Filion, Tyler, 2002). Since shutting down in 1971, several different companies have taken ownership of the mine, including Wilanour Resources, Esso Minerals Canada and Inco Gold Inc. In 1984- 1985, Esso spent 5.3 million dollars on exploration and drilled 23,707 feet from underground and surface. Between 1988-91, Inco Gold Inc. drilled 40,059 ft from surface and 1,605,972 ft from underground. From 1992-1996, the Cochenour property was on the market, with many companies including Placer Dome reviewing the data. In 1997, Goldcorp Inc. purchased 100% interest in Cochenour-Willans Mine and the properties. Little besides compilation work was done until 2002. In 2002, exploration included two drill holes and 8 wedge holes totalling 5176 meters. During 2004, 3 drill holes and 3 wedge holes totalling 2851 meters was drilled. In 2006, exploration was ramped up to 36 drill holes and 3 wedge holes totalling ~ 17,700 meters.2008: Gold Corp conducted drill program, testing for the extension of the Cochenour gold bearing structures between the Gold Eagle and Cochenour zones.

Mar 15, 2012 (A McKee) - Balmer-aged mafic volcanics, predominately fine grained, pillowed or massive flows. Basalts are cut by numerous small dioritic to lamprophyre dykes and occasional felsic intrusions. The lower portion of the drill holes include intervals of intercalated bedded interflow clastic sedimentary rocks and sulphide rich Banded Iron Formations and cherts. Basalts are commonly variably altered, green (chloritized), grey (bleached), to brown (biotized) with localized silicification. Carbonitization is the most common type of alteration.
Mar 15, 2012 (A McKee) - Assays up to 18.404 g/t over 1 m Gold mineralization is often structurally controlled and is commonly associated with increased silicification as pervasive alteration or veining and arsenopyrite mineralization. Also VG was found within the interflow clastic/chemical sediments in some of the holes.
Aug 10, 2022 (Q Unknown) - Pre-1945: grab samples up to 0.4 opt Au; channel samples up to 0.06 opt Au/2 ft.
