Did the Northland Pyrite Mine and Thompson-Lundmark Mine contain more than just gold?
Northland Pyrite Mine The Northland Pyrite Mine, also known as James Lake Mine, Rib Lake Mine, Harris Mine or simply Northland Mine, is an abandoned underground mine in Northeastern Ontario, Canada, located on the southwestern shore of James Lake in Best Township of Temagami. It was operated by the Northland Mining Company during the early 1900s with the construction of a 91 m shaft and many open-cuts north of the shaft. Minerals present at the mine include chalcopyrite, pyrite and pyrrhotite, deposited in Precambrian volcanic rock of the Canadian Shield.
Gold mining in Virginia Most gold mining in Virginia was concentrated in the Virginia Gold-Pyrite belt in a line that runs northeast to southwest through the counties of Fairfax, Prince William, Stafford, Fauquier, Culpeper, Spotsylvania, Orange, Louisa, Fluvanna, Goochland, Cumberland, and Buckingham. Some gold was also mined in Halifax, Floyd, and Patrick counties.
