Some of Cementation’s deeper jobs
The world’s mining companies are delving ever deeper into the surface of earth in search of mineral wealth and Cementation Ltd. of North Bay, Ont. has designed and constructed some of the deepest shafts on record, including the following:
On November 14, 2014, after six years work, Cementation completed the production shaft at the Resolution Copper project in Superior, Arizona. It is 8.7m in diameter and 2152m—the deepest single lift shaft in the U.S. The Resolution mine is expected to produce 25 per cent of annual U.S. copper output.
Cementation’s South African subsidiary broke ground on the twin shafts–production and ventilation–at Gold Fields’ South Deep Gold Mine in June 1995. They were commissioned in November, 2004. The production shaft is 3042m deep, the world’s deepest single lift shaft.
Glencore’s Kidd Creek Mine D–a copper-zinc producer–is now the world’s deepest base metal mine. Cementation designed and constructed D shaft, which starts 1456m below surface and plunges 1607m to a depth of nearly 3100m.
