Margaux Resources Ltd. is a Calgary based, publicly traded resource company, currently focused on their Jersey Emerald Tungsten-Zinc Property, located in the southeast portion of British Columbia. The Jersey Emerald Property has four distinct deposit types. These are carbonate-hosted lead-zinc (Irish style massive sulphide), sedex type zinc-silver-copper, and gold-bismuth skarn and tungsten skarn mineralization. The Emerald/Dodger Tungsten mine was the largest tungsten producer in British Columbia and second largest in Canada. It closed in 1973 due to poor tungsten prices and the expectation of the implementation of a "super royalty". With the recent substantial increase in tungsten price the company will be re-evaluating the existing reserves and implementing a program designed to define additional areas on the Property that have high tungsten potential. Margaux Resources holds interests in various oil and gas properties located in the Western Canadian Sedimentary Basin. The current projects are the Jersey Emerald Tungsten-Zinc Property, and the Jumpbush oil and gas production in south eastern Alberta.
