North Kearsarge Mine

The success that the Osceola Mine enjoyed along it’s amygdaloid lode south of Calumet was encouraging, but like any mining company in the Keweenaw knew, good fortunes could change in an instant. The company quickly looked to expand its empire and insure its longevity by investing in new mines along new lodes. It would be a young mine which had recently discovered the highly rich Kearsarge Amygdaloid lode that first perked Osceola’s interest. This was the Kearsarge Mine, a mine Osceola ended up grabbing for themselves in 1897.

By the time of Osceola’s purchase the Kearsarge had already been in production for over a decade. The mine had not only made a small profit during this time, but had also managed to pay out modest dividends to its investors. But with the benefits of both Osceola’s mills and experienced management, the mine was able to grow those profits and dividends substantially. The Kearsarge would continue to produce copper for the next 50 years, not just for the Osceola but for C&H as well.
