An underground copper mine located near Norwich, Michigan. A rich vein of copper was discovered in 1846 near the Ontonagon River and work was started in 1850. The American Mining Company of Vermont organized the Norwich Mining Company in 1855. Work continued until 1858, when the mine was leased on tribute. In 1863, the company was reorganized and consolidated with the Windsor Mining Company. In 1864, the company merged with the Hamilton Mining Company. The mine was closed in 1865, but work continued on tribute until 1869. In 1899 and 1900, some work was done at Norwich under the name of Essex Mining Company. The mine produced an approximate total of 993,000 pounds of refined copper. Collectors can find copper, quartz, and some silver. [MINDAT]
