What is now known as the Kearsarge Lode could of easily been the Wolverine Lode if not for but a few hundred feet. It was 1882 when a small group of local investors sunk the first Wolverine shaft along what is now known as the Kearsarge Lode, only to miss the copper-rich lode by a narrow margin. Without the discovery of any substantial copper deposits this early attempt was quickly abandoned. Several years later the Kearsarge Mine would open its doors to the north and discover what would become known as the Kearsarge Lode.
But the Wolverine mine’s early misfortune did not deter its destiny. After the Kearsarge Mine’s success the old Wolverine mine was re-opened through the optimistic determination of John Stanton. A series of new shafts were sunk – this time into the newly discovered and copper rich Kearsarge Lode. The narrow section of the this lode that ran through the Wolverine property proved highly rich in copper, perhaps the richest along the entire lode. Before long the mine’s success enabled the company to construct its very own stamp mill at Gay, and smelt its rock at the newly constructed Michigan Smelter to the south. When all was said and done, the Wolverine would become one of the most profitable mines in the Keweenaw. At its peak the mine was producing 30 pounds of copper for every ton of stamped rock, the highest yield of any other Amygdaloid mine in the region.
