During World War II, Frood Mine alone accounted for a full 40 per cent of all the nickel used in Allied artillery production. In 1989, Frood Mine shared the John T. Ryan Trophy for the best occupational safety record among Canadian mines in the previous year.
The mine is named for Thomas Frood, an employee of the federal department of Crown lands who prospected and staked many of the early mining claims in the area. A major arterial road in the city is also named for Frood.
On June 8, 2011, two miners were killed at Stobie Mine when they were struck by a run of muck at an ore pass on the mine's 900-metre level (3000 ft level). Ontario Ministry of Labour fined the company Vale Limited $1,050,000 under the Occupational Health and Safety Act after Vale pleading guilty to three counts related to mine safety.
In 2012, Vale Limited announced that production at the mine will be suspended at year's end.
