Sudbury Mining Solutions Journal is a magazine that showcases the mining expertise of North Bay, Timmins and Sudbury. This article is from the December, 2013 issue.
The mineralization at Vale’s Totten Mine is so rich, ribbons of copper, nickel and precious metal can be viewed at surface just by walking through the parking lot.
“It’s pretty interesting for anybody who likes geology,” said Lance Howland, Totten’s chief mine geologist. “They can go out for their lunch break to look at exactly what’s here, and that’s pretty much what you’d see underground.”
Totten Mine is situated along the Worthington Offset, one of the fractures resulting from the creation of the Sudbury Basin 1.8 billion years ago. Offset deposits like Worthington were formed when pressure caused by molten material cooling around the basin pushed its way into a fracture.
“(The molten material) carried with it the copper, nickel and precious metals, and formed multiple deposits along that string. One of them was Totten Mine,” Howland said. “It’s a pretty unique story and we’ve got some very interesting deposits that a lot of people around the world have come here to see given how unique it is.”
