Named after James Bruce, who was appointed as Governor General of Canada in 1846, the town of Bruce Mines (otherwise known as the “Jewel of Lake Huron”), was first established in that same year as a copper mining area by John Keating, Indian Agent, after exploration with Arthur Rankin, a land surveyor.  Keating began mining in December, employing skilled Cornish miners who had recently emigrated from England.  The Huron & St. Mary’s Copper Co. was formed to manage the miners.

The Bruce Mines changed ownership several times between 1847 and 1944, when they were decommissioned.  Flooding and cave-ins in 1876 ended the 30-year period of active mining history.  In the 1870's, agriculture and logging prospered in the wake of uncertainty with the mines.  The Township of Plummer Additional became incorporated in 1891 while Northern Ontario's first town, the Town of Bruce Mines was officially incorporated in 1903.

Several attempts to re-open the mines in the early 1900's saw only limited success by Mond Nickel, who shipped the quartz-copper flux ore to Sudbury.  Mond Nickel shut down the Bruce Mines in 1921.

The mines were decommissioned in 1944 and forestry activities have declined, but agriculture, aggregate extraction and tourism continue as the main economic activities in the area.  The Township of Plummer Additional depends on Bruce Mines and other urban centres for most of its commercial and community services.

Single jacking on upper holes was tiring on the hand and arm.  To lessen the fatigue, old timers used a thong on the hammer handle, which permitted the opening and relaxing of the hand on the back stroke.
