Sphinx Resources Ltd. (formerly Donner Metals Ltd.) is a Canadian company focused on exploration of precious and base metals within mining rights in Quebec. It is listed on the TSX Venture Exchange. The company was formerly named Donner Metals Ltd., headquarters are in Vancouver, and active in other provinces, but changed names in 2014 and moved its headquarters to Montreal, Quebec. As Donner, its principal project was a 35-65 joint venture with Glencore Xstrata (the operator and 65% interest holder) in Matagami, Quebec. History The company was founded in 1996 as a mining exploration company prospecting in South Voisey's Bay, Newfoundland and Labrador. While this project eventually stalled, along the way a relationship with Falconbridge was developed. In 2006, Donner signed a deal with Falconbridge, wherein Donner was required to spend $20 million by May 31, 2011, plus an additional $5 million if a brand new discovery was made. The deal effectively makes Donner "the funding vehicle for exploration within the Matagami base metal camp". Glencore Xstrata can earn back a 15% interest on each of the 6 JV areas. Glencore Xstrata has earned the additional 15% in the Bracemac-McLeod and South Flank JVs. Matagami Project Since signing the deal, the joint-venture partners have focused their efforts on the South Flank and Bracemac-McLeod properties. The property is located 6 km southeast of Xstrata's Matagami Mill.
