What precious metal did both McIntyre Mines and the Kemess Mine dig for?
Kemess Mine The Kemess Mine was an open-pit copper and gold mine, located just northeast of the foot of Thutade Lake, at the head of the Finlay River, in the Omineca Mountains of the Northern Interior of British Columbia, Canada. It was operated by Royal Oak Mines from 1998 to 1999, when it was bought by Northgate Minerals. Northgate operated the mine until its closure in 2011; that year Northgate was taken over by AuRico Gold. In 2014 AuRico Gold partitioned off its portion of kemess Mine ownership creating a new company called AuRico Metals. AuRico Metals is actively implementing permits for a block caving mine.
Kermes mineral Kermes mineral or Alkermes mineral was a compound of antimony oxides and sulfides, more specifically, antimony trioxide and trisulfide. It can be made or obtained in the laboratory by the actions of potassium carbonate (KCO) on antimony sulfide. The compound is reddish brown in color and described as a velvety powder which is insoluble in water. It was used extensively in the medical field until the general use of antimony compounds declined due to toxic effects.
