Trelawney Intersects 10.06 Metres of 15.58 g/t Gold Between the Cote Lake and Chester 2 Deposits

TORONTO, ONTARIO--(Marketwire - May 27, 2010) - Trelawney Mining and Exploration Inc. (the "Company") (TSX VENTURE:TRR) announces new drill results from exploration drilling east of the Cote Lake Deposit on the Chester Project located halfway between Timmins and Sudbury in northern Ontario. The results being reported are from section 97+00 E which is located approximately halfway between the Cote Lake Deposit and the western end of the Chester 2 Deposit. Drilling targeted historical high grade gold mineralization reported under Cote Lake. The results appear to be more akin to the type and style of mineralization reported to occur in the Chester 2 Deposit and may be the western extension of the Deposit's high grade C and C prime zones. Rock types encountered in the holes are consistent with the Chester intrusive complex which hosts the majority of the mineralization on the Chester Project. All of the drill holes reported intersected extensive zones of intense bleaching and sericite alteration associated with the gold mineralization.

Due to the early spring break-up drilling was curtailed resulting in only three of the six planned drill holes being completed and the abandonment of hole CL 10-02 on which a second rig was drilling. Exploration drilling on possible extensions of this mineralization where it may come to shore will be followed-up this summer. Additional drilling in the immediate area of these holes on Cote Lake will be conducted on ice next winter. Greg Gibson, Trelawney's President and CEO commented, "We are extremely encouraged with the results from our initial winter drilling on ice under Cote Lake. These results are similar to those from the Chester 1 property located three kilometres to the east where we are currently in the final permitting step for an underground exploration program. We are confident that the property contains both Archean high grade gold vein systems and bulk tonnage targets such as the recently discovered Cote Lake Deposit. Trelawney's ongoing compilation of historical data on the Chester Project continues to define additional targets with similar potential and these will be evaluated during the summer field season." Trelawney Mining and Exploration has implemented a Quality-Control, Quality Assurance program to ensure best practice principals are being applied in the sampling and analysis of the drill core. Samples are crushed to -8 mesh then a 1,000 gram subset of each sample is pulverized to 90% passing -150 mesh. Assays have been completed using a standard fire assay with a 30 gram aliquot and an AA finish. For samples that return values of between two to five grams per tonne gold, another pulp is taken and fire assayed with a gravimetric finish. Samples returning values greater than five grams per tonne are re-analyzed by pulp metallic analysis. NQ size drill core is saw cut, and half the drill core is sampled in standard intervals. The remaining half of the core is stored in a secure location. The drill core is transported in security-sealed bags to the Accurassay prep lab in Sudbury, Ontario by Trelawney personnel. Accurassay is an ISO/IEC 17025 certified Laboratory by the Standards Council of Canada. In addition to quality assurance controls at the laboratory, blanks and certified standards have been inserted into the sample stream at random intervals. 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. Trelawney is a Canadian junior mining and exploration company with a strategic focus on "Quality Ounce" gold deposits. The Company's current focus is directed towards the development and continued exploration of its newly acquired Chester Project, located in Chester Township 20 kilometres southwest of Gogama, Ontario.
