[1] In late July 1911, Bill Wright and his brother-in-law Ed Hargreaves discovered the first visible gold in what would later become the Kirkland Lake camp.

1 shaft was sunk to a depth of 85 feet (26 metres).

By the end of its production, the Wright-Hargreaves was the deepest mine in the Kirkland Lake camp with workings at the 8,200-foot (2,500-meter) level.

Production ceased following a serious rock burst underground in August 1964.

Final salvage activities and clean up were completed in 1965, with a total production of 4,821,296 ounces (136,681,400 grams) of gold at an average grade of 0.49 ounces per ton (15.31 grams per metric ton).
