The northern Manitoba city of Thompson could be home to a new mining mega-development from Vale, which is exploring minerals deep underground.
News of a potential big development is being cautiously welcomed in Thompson, which was devastated by news in 2010 that Vale — the city’s largest employer — would shut down its nickel smelter and refinery there by 2015.
Vale is currently testing ore samples in a project area it calls 1-D, about 3,800 to 4,200 feet underground in the company’s T-3 mine shaft. Preliminary testing in 1-D shows a deposit rich in nickel and copper deposits and also containing some cobalt and precious metals.
Vale says it has been mining in 1-D for years, but officials believe now is the time to dig deeper in an largely untapped section of the deposit extending as much as 6,800 feet underground in some places.
According to the company, geologists have been pulling up core samples containing extremely high-grade nickel. Based on their tests, the geologists believe there are at least 10 million tonnes of nickel present.
