In 1885 F. J. Eyre discovered the Evans Orebody. 1889-1899 the Evans Mine was in production by Canada Copper Company in open pits and underground to a depth of 250’. In 1967 development of the Copper Cliff South Mine started with the collering and 50’ of sinking of the #2 Shaft. In 1968, the #1 Shaft was collared and sunk 59’ and the #2 Shaft was sunk to 1357” with the establishments of 5 levels and a combined drifting/cross-cutting of 331’. In 1969 the #1 Shaft was sunk to 436’ with 2 levels established; the #2 Shaft was sunk to 2301’ with a further 5 levels established; a ramp from the surface to the 500 Level was driven, 91 raises and a total of 1783’ of drifting and cross-cutting were completed. In 1970 the #1 Shaft was continued to 2230’ and 7 more levels were established, 25,140’ of drifting/crosscutting, 4658’ raising, and 52,371’ of drilling were achieved in 211 underground collared drill holes. In 1971 commercial production started. 2008: Operations suspended. 2022: Production recommenced under Vale Canada Ltd.
Aug 19, 2015 (L Hall) - The ore from the Copper Cliff South Mine is from the Copper Cliff Offset, a quartz diorite dike that extends from a funnel shaped “Copper Cliff Funnel” embayment in the Sudbury Igneous Complex contact south across Huronian Supergroup metasedimentary rocks and Nipissing Diabase intrusions. At the Copper Cliff South Mine the Copper Cliff Offset is offset in a dextral sense (map view) by the Evans Fault. Orebodies in the offset are deeper south of the Evans Fault than they are to the north of it.
Aug 19, 2015 (L Hall) - The host lithology of the Copper Cliff South Mine orebodies is the Copper Cliff Offset quartz diorite dike. Orebodies in the Sudbury Offset environment are generally constrained to the inclusion bearing facies (IQD) of the quartz diorite offset dike. Fragments of metasedimentary, metavolcanic, amphibolite and gabbro that range from centimeter to 10’s of meters in size in a crystalline quartz diorite groundmass characterizes the IQD facies of the Copper Cliff Offset at the Copper Cliff South Mine.
