The Coleman Mine is an underground nickel and copper mine operated by Vale 45 kilometres (28 mi) northwest of Sudbury, Ontario, Canada. It was the flagship mine of Vale's Sudbury operation.[2] The mine recently implemented the use of electric haul vehicles and installed an underground 4G LTE network.[2]
The mine is operated by a staff of 545 workers.[2]
Ore is transported by rail or by truck for processing at Clarabelle Mill.
Geology
[edit]Coleman is located on the north ridge of the Sudbury Basin. It is a magmatic style ore deposit with two kinds of mineralization. The upper area called the Main Ore Body (MOB) consists of a nickel and copper rich zone of massive sulphides known locally as a contact nickel deposit [3]. The lower area of the mine called the 153 and 170 Ore bodies contains large veins of Chalcopyrite and Bornite, strongly enriched in PGMs known as a footwall breccia deposit [4].
Mining
[edit]Culture
[edit]Coleman is the farthest mine from the center of Vale's operations in Sudbury, giving it a unique culture. The sign leading into Coleman proudly reads "It's Worth the Drive" giving a nod of respect to all the employees who commute long distances across the whole basin (45 km each way from Downtown Sudbury)[2]
