Canstar Resources Announces Definitive Agreement with Freeport-McMoRan of Canada Limited to Complete Purchase of a Purchase Option for 50% of the Mary March Property, Newfoundland

TORONTO, ONTARIO--(Marketwire - April 19, 2012) - The directors of Canstar Resources Inc. (Canstar) (TSX VENTURE:ROX) wish to announce that the Company has, subject to regulatory approval and closing, entered into a definitive agreement with Freeport-McMoRan of Canada Limited (formerly Phelps Dodge Corporation of Canada Limited) (FMCL) to complete Canstar's acquisition of FMCL's option (Option) to acquire a 50% joint venture interest in the Mary March mineral property located in the Buchans area of Newfoundland And Labrador pursuant to the letter of intent entered into by Canstar and FMCL in 2003.

The remaining 50% joint venture interest is held by Noranda Mining and Exploration Inc. (part of the Xstrata group of companies) (Xstrata), who is also the optionor. Upon exercise, the Option grants the optionee a right of first refusal on Xstrata's 50% joint venture interest in the Mary March property. Canstar is the Operator of the joint venture.

As previously reported, the Mary March property is located in the Buchans area of Newfoundland and Labrador, 20 kilometers northeast of the formerly producing Buchans mine (16.2 million tons @ 14.50% zinc, 7.56% lead, 1.33% copper, 126 g/t silver and 0.9 g/t gold). Previous drilling on the Mary March property occurring between 1999 and 2000, had discovered Buchans type massive sulphides, with one hole averaging 10.33% zinc, 1.62% lead, 0.66% copper, 118 g/t silver and 4.1 g/t gold over 9.23 metres. No exploration has been carried out on this zone since 2000.

The Company has definitive plans to conduct a comprehensive exploration program over this property, including drilling and geophysics, as soon as the purchase of FMCL's Option is completed and formal arrangements with Xstrata have been finalized.

On behalf of the directors I would like to express our appreciation to our shareholders for their patience with the delay in moving forward with the property exploration plans.

On behalf of the Board of Directors

Harry J. Hodge, P. Eng., Chairman
