Osisko Mining, a mineral exploration company, and Gold Fields, a gold mining company, formed a joint venture in a $498m deal. “We are very pleased to partner with Gold Fields on the Windfall project and our exploration property portfolio. Today is the start of what we believe will prove to be a long and fruitful partnership with Gold Fields at Windfall, and in what we both believe is a significant emerging gold district in Québec. This partnership further strengthens our strong balance sheet, allows us to significantly de-risk Windfall and brings us a very important step closer to realizing our objective of becoming a leading Canadian gold producer," John Burzynski, Osisko Chairman and CEO.
