Trelawney Files Resource Report for the Cote Lake Gold Deposit

TORONTO, ONTARIO--(Marketwire - April 25, 2011) - Trelawney Mining and Exploration Inc. (the "Company" or "Trelawney") (TSX VENTURE:TRR)(FRANKFURT:RTW) announces that it has filed the report entitled: "Technical Report on the Cote Lake Deposit, Chester Property, Ontario, Canada" with regulatory authorities. The report dated April 21, 2011, was authored by William E. Roscoe, P.Eng., and R. Barry Cook, P.Eng., of Roscoe Postle Associates Inc. (RPA). The report includes the initial mineral resource estimate on the Cote Lake Gold Deposit previously released on March 7, 2011.

The main highlight of the report is an Inferred Mineral Resource estimate for the Cote Lake Gold Deposit of 131 million tonnes averaging 1.00 g/t Au for 4.2 million ounces of contained gold at a cut‐off grade of 0.3 g/t Au. The estimate and technical report conform to National Instrument 43-101 Standards of Disclosure for Mineral Projects (NI 43-101). The effective date of this mineral resource estimate is March 4, 2011.

The Cote Lake Gold Deposit, located on the Chester Property halfway between Timmins and Sudbury in Northern Ontario, consists of low to moderate grade gold +/- copper mineralization which is associated with brecciated intermediate to felsic, and locally mafic intrusive rocks. Mineralization occurs in the form of disseminated and fracture-controlled sulphides which generally correlate to the gold values. Visible gold is commonly observed. The zones are bleached with the prevalent alteration being feldspathic, chloritic and biotitic. The nature of the alteration and mineralization is indicative of a porphyry-style deposit.

David Beilhartz, Vice President, Exploration for Trelawney Mining and Exploration, a Qualified Person under NI 43-101, has prepared or supervised the scientific or technical information for the property and verified the data disclosed in this press release. William E. Roscoe, P.Eng., of RPA, a Qualified Person under NI 43-101, has reviewed and approved this press release as it pertains to the mineral resource estimate.

Trelawney is a Canadian junior mining and exploration company with a focus on Archean gold deposits. The Company's current focus is directed towards the development and continued exploration of the Chester Project, located in Chester Township 20 kilometres southwest of Gogama, Ontario.
