Trelawney Intersects 316.00 Metres of 1.38 g/t Gold and 312.00 Metres of 1.17 g/t Gold from Infill Drilling at Cote Lake

Trelawney Mining and Exploration Inc. (the "Company" or "Trelawney") (TSX VENTURE:TRR)(FRANKFURT:RTW) announces the results from 13 additional holes drilled on the Côté Lake Deposit on the Chester Project located halfway between Timmins and Sudbury in Northern Ontario. The results are from the ongoing infill and expansion drilling on the Côté Lake Deposit. Drilling continues to intersect significant widths of low to moderate grade gold mineralization from the infill drilling at the Côté Lake deposit. Infill drilling has been conducted in various orientations and angles to aid in confirmation of continuity and assist in geological modeling.

The Côté Lake Deposit currently hosts an indicated resource of 35 million tonnes averaging 0.82 g/t for contained gold of 0.93 million ounces and an inferred resource of 204 million tonnes averaging 0.91 g/t for 5.94 million ounces of contained gold. A cut-off grade of 0.3 g/t Au was used for the estimate as reported in Trelawney's press release dated February 24, 2012. To date, mineralization of the Côté Lake Deposit has been intersected over a strike-length of 1,200 metres and remains open in several directions along strike and at depth. The Côté Lake Deposit consists of low to moderate grade gold +/- copper mineralization which is associated with brecciated intermediate to felsic, and locally mafic intrusive rocks. The nature of the alteration, style of mineralization and age-dating all indicate the deposit is an Archean porphyry system.

The Company continues to explore its considerable land holdings in the Swayze greenstone belt. The current drill program on the Côté Lake Deposit continues with eleven drill rigs, four focusing on expansion drilling and seven drills on infill drilling. An additional drill rig is conducting regional exploration and condemnation drilling.

Greg Gibson, Trelawney's President and CEO commented, "We are very pleased that the ongoing infill drilling continues to confirm the significant widths and grades of mineralization similar to our original wider-spaced drilling."

Trelawney has implemented a quality-control, quality assurance program to ensure best practice principles 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 5 grams per tonne are re-analyzed by pulp metallic analysis. Occasionally holes or partial holes are reported with only the original fire assay. 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 of Trelawney, a Qualified Person under National Instrument 43-101, has prepared or supervised the scientific and/or technical information for the property and verified and approved the data disclosed in this press release.

For complete disclosure of the mineral resource estimate discussed in this press release, please refer to the Technical Report on the Côté Lake Resource Update, Chester Property, Ontario, Canada reported in accordance with NI 43-101 requirements, signed by W. Roscoe and B. Cook, Roscoe Postle Associates Inc., effective February 24, 2012. Investors are cautioned that mineral resources are not mineral reserves and do not have demonstrated economic viability.

On April 27, 2012, Trelawney announced that it had entered into a definitive agreement with IAMGOLD Corporation ("IAMGOLD") pursuant to which IAMGOLD, through a wholly-owned subsidiary, has agreed to acquire all of the issued and outstanding common shares of Trelawney. Under the terms of the agreement, each Trelawney shareholder will receive $3.30 in cash for each Trelawney share held. The transaction will be carried out pursuant to a statutory plan of arrangement (the "Arrangement"). A special meeting of Trelawney shareholders to consider the Arrangement is scheduled to be held on June 15, 2012 at 11:00 a.m. (Toronto time) at the Toronto Board of Trade, 1 First Canadian Place, 3^rd Floor, Toronto, Ontario. Completion of the proposed Arrangement is subject to a number of customary conditions, including approval of the Ontario Superior Court of Justice and the receipt of shareholder approval. Assuming Trelawney shareholders approve the Arrangement at the special meeting of shareholders, final court approvals are obtained and all other conditions to the Arrangement are satisfied or waived, the Arrangement is expected to close by the end of June.
