“The mine at North Kearsarge (and its sister mine at South Kearsarge) enjoyed the benefits of an association with one of the more wealthy mine companies along the Copper Country. The Osceola Consolidated controlled not only these mines, but also the six shafts of the Osceola as well as sharing owners with C&H’s rival – the Tamarack Mine. They operated past the turn of the century when eventually they shared the fate of all successful competitors to C&H. C&H bought them out.

This buy out in 1909 meant the North Kearsarge enjoyed an extended life. They depression took a heavy toll to the industry in the 30′s and the North and South Kearsarge Mines ceased production. But buoyed by wartime copper prices, C&H reopened the North Kearsarge in 1942 and operated it profitably until 1956 when it was closed for good.”
