SHOWCASE MINE OF THE WEEK - CREIGHTON UNDERGROUND NICKEL MINE!!
Creighton, an underground nickel mine located in the City of Greater Sudbury, Ontario, Canada, is the tenth deepest mine in the world. It is also the world’s deepest nickel mine, with its mining depth extending up to 2.5km. The mine is owned and operated by Vale. The mine was discovered in 1991. The first production from the Creighton open pit started in 1901. Underground operation commenced in 1906. Current mining methods include shrinkage mining and mechanised undercut-and-fill mining. The large-diameter blasthole method combined with vertical retreat mining has also been introduced recently. Extracted ore is crushed underground and sent by rail to the Clarabelle Mill for processing. The mine produced 797,000t of ore grading 1.80% copper and 1.84% nickel in 2012. Exploration drilling carried out at Creighton in 2007 confirmed mineralisation at depth. The Creighton Deep exploration Project is believed to have almost doubled the proven and probable reserve to 32Mt grading 1.9% to 2.2% nickel and 2% to 2.3% copper - Mining Technology.
