Silver Islet
Silver Islet is a tiny rock off the north shore of Lake Superior where silver was found in 1868 and mined until 1884.[1]
The Montreal Mining Company's Thomas Macfarlane planned a geological map; his assistant Gerald C. Brown noticed a galena vein, and John Morgan found the first nuggets on 10 July 1868. A shaft was sunk 1,230 feet and silver valued at $3,250,000 taken before 1884, the first truly successful mine in the district.[1] A plaque was unveiled on 14 August 1960.[2]
