The mine, formed in 1828 through the merger of Treskerby Mine and Wheal Chance, operated on lodes situated in metamorphosed killas atop the northern slope of the Carn Marth granite. The Treskerby sett abutted Wheal Boys to the west, demarcated by the County Crosscourse, which also delineated the northern boundaries of both mines. To the east, it bordered Wheal Chance. Operations spanned both sides of the Redruth-Truro road, although much of this area has since been developed. Originally, the southern extent of the sett reached 900 yards southeast of Treskerby village and once encompassed Park-an-Chy Mine. Some dumps remain in woodland south of the Redruth-Truro road.

Mining activities commenced as early as 1800, ceasing shortly after the 1828 amalgamation. In 1860, the mine was revived and partially dewatered. From 1815 to 1832, the mine yielded 47,545 tons of 9.5% copper ore, with the Treskerby section also producing 9 tons of black tin during this period. Between 1922 and 1927, an additional 18,500 tons of 9% copper ore were extracted. Prospecting efforts in 1938, spurred by the discovery of wolframite-bearing ore in Treskerby Mine dumps, failed to locate the source of the tungsten ore.
