A HISTORY OF THE NORTHERN PENINSULA OF MICHIGAN AND ITS PEOPLE By ALVAH L. SAWYER 1911 THE LEWIS PUBLISHING COMPANY The Michigan Copper Mining Company was organized January 5, 1899, with a capital of $2,500,000. Its location comprises 6,686 acres and includes 4,870 acres of mineral territory, 1,466 of timber and mis- cellaneous lands, and a 150-acre mill site. The main tract is three miles east and west, by four and a half north and south, active operations be- ing conducted at Rockland, northeast of the center of the county. In- cluded in the Michigan location are these three old mines, the Minnesota, Rockland and Superior. It was in the Minnesota tract that the prehistoric pits were discov- ered, noted in the general chapter on copper mining, and which led to the opening of the modern mine in 1847. In one of the pits was a "6-ton mass of copper raised on skids, on top of which grew a hemlock tree having nearly 400 rings of annual growth. Immense masses of virgin copper were taken from the Minnesota, the largest (found in 1856), measuring 12 feet 6 inches by 18 feet 6 inches by 46 inches, weighing 527 short tons and requiring the work of 20 men for 15 months in cut- ting it into pieces small enough for hoisting (See Copper Manitou). From 1847 to its closing in 1870 the Minnesota produced 34,704,668 pounds of fine copper and paid $1,820,000 dividends. The Rockland, ly- ing east of Minnesota, was operated in 1853-70, with an output of 6,210,309 pounds, and the Superior, about a mile east of the present workings, made 567,331 pounds during the periods of its activity, 1856- 69 and 1876-9. The present Michigan mine is a combination of two new mines and a reopened old location, its shafts being sunk on a bed which outcrops a few feet north of the North Minnesota fissure. A few miles to the north- east are the Mass and Adventure mines. The Michigan mine has ten miles of underground workings; employs about 450 men; is opened by three shafts and produces from 1,900,000 to 2,900,000 pounds of copper- annually. Its new stamp mill is about a mile north of the Mass plant at Keweenaw Hay, water being secured through a 1, 200-foot tunnel. A distinctive feature of the copper which is produced by the Michigan mine is its high electrical conductivity, in which quality it surpasses all other Lake Superior varieties.
