Gold

This specimen showcases bright yellow high-grade gold tightly packed into quartz veinlets within an altered basaltic rock matrix accompanied by some pyrite, and it weighs 67g. Gold content is estimated to hover somewhere around an ounce. It comes from the collection of a geologist that once worked at the Kerr-Addison mine many decades ago. Located in Timiskaming, Ontario, this mine was one of North America’s most significant gold producers, reaching a depth of 5,000 feet before its closure. At its peak in 1960, it was the largest gold-producing mine in North America, and this specimen stands as a testament to its remarkable ore quality. Development of the property began in 1907, but full-scale production did not commence until 1938, following its acquisition by Kerr-Addison Mines Ltd. The mine changed ownership several times over the years but ultimately ceased operations in 1996, with a total production of approximately 10.5 million ounces of gold. This super rich specimen serves as a historical and mineralogical record of the extraordinary deposits that once made Kerr-Addison a world-class mining operation.
