Brazilian multi-national metals and mining firm Vale has opened the Totten mine at Sudbury Basin in Ontario, Canada.
The Worthington-based mine will produce copper, nickel and precious metals over the next 20 years.
The company said that Totten mine features the latest in mine technology and safety automation, including a wireless underground communication system and location tracking on mechanical and personal protective equipment.
The mine's design also includes several environmental features that will minimise its operating footprint and impacts on the surrounding area.
Construction of the Totten mine will cost more than $700m and take seven years to complete.
Vale Canada president and CEO and Vale executive director of base metals and information technology Peter Poppinga said that Totten mine is the company's first new mine in the Sudbury Basin for more than 40 years and it represents a significant investment in the future of its operations in Ontario and across Canada.
"The opening of Totten mine reinforces the strong confidence we have in our world-class base metals assets to deliver sizeable value through all commodity cycles," Poppinga said.
"Vale is committed to its future in Canada and across base metals and we are pleased to be able to celebrate this historic milestone for our company and the Greater Sudbury community."
Vale signed an impact benefits agreement with Sagamok Anishnawbek First Nation in 2012, to share the mine's economic benefits.
Sagamok Anishnawbek First Nation chief Paul Eshkakogan said: "Sagamok Anishnawbek congratulates Vale on their achievement and our First Nation looks forward to continuing to participate in the Totten mine project, including through employment, mine service delivery and environmental stewardship."
