TORONTO, ONTARIO--(Marketwire - May 25, 2011) -
Trelawney Mining and Exploration Inc. (the "Company" or "Trelawney")
(TSX VENTURE:TRR)(FRANKFURT:RTW) announces that as a result of a review by staff of the Ontario Securities Commission in connection with the filing of the Company's preliminary prospectus dated May 16, 2011, we are issuing the following press release to clarify our disclosure regarding the Chester 1 and Chester 2 Projects.


The Company has previously disclosed the results of economic analysis on historical estimates for the underground workings at the Chester 1 and Chester 2 Projects which consisted of technical information relating to throughput rates, gold production, cash costs per ounce, cash flow projections and mine life. These historical estimates were completed prior to the implementation of National Instrument 43-101 ("NI 43-101") and such disclosure is considered to be too speculative to have economic considerations applied to them. As a result this information did not comply with the disclosure requirements of NI 43-101 and should not be relied upon.


In light of the positive results of the recent initial mineral resource estimate for the Cote Lake Deposit, it is Trelawney's intention to reduce underground operations at the Chester 1 Project and focus on exploration and diamond drilling on the Cote Lake Deposit and other areas of the Chester Property.


Management of the Company feels it is in the best interests of the Company to concentrate on the Cote Lake Deposit and looks forward to reporting on the continuing exploration efforts to define the limits of the deposit.



This news release may contain forward-looking statements including but not limited to comments regarding the timing and content of upcoming work programs, geological interpretations, receipt of property titles, potential mineral recovery processes, etc. Forward-looking statements address future events and conditions and therefore, involve inherent risks and uncertainties. Actual results may differ materially from those currently anticipated in such statements.
