TORONTO, ONTARIO--(Marketwire - March 5, 2012) - Trelawney Mining and Exploration IncTrelawney Mining and Exploration Inc. (the "Company" or "Trelawney") (TSX VENTURE:TRR)(FRANKFURT:RTW) announces the results from 11 additional holes drilled on the Cote 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 Cote Lake Deposit. Drilling continues to intersect significant widths of low to moderate grade gold mineralization from the infill drilling at the Cote Lake Deposit.

The Cote Lake Deposit currently hosts an indicated resource of 35 million tonnes averaging 0.82 g/t for 0.93 million ounces of contained gold 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 Cote Lake Deposit has been intersected over a strike-length of 1,200 metres and outcrops at two known locations 500 metres apart. The zone remains open in several directions, and at depth on all sections that have been drilled. In section, the zone attains widths of up to 300 metres. The mineralization, delineated by drilling to date, coincides well with a NE-SW-trending IP anomaly. The Cote 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 and mineralization and age dating all indicate the deposit is an Archean porphyry system.

A total of 11 diamond drill rigs are presently operating on the Company's vast land holdings in the Swayze area. The drill program on the Cote Lake Deposit will continue with nine drill rigs, one focusing on expansion drilling and eight drills on infill drilling. The final two drill rigs are conducting regional exploration and condemnation drilling.

Greg Gibson, President and CEO of Trelawney 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. Over the winter months our focus has been to work on defining areas within the wetlands, and we look forward to resuming the aggressive expansion phase of our drill program once spring break up is over."

Notes:
- True widths of intersections are unknown at this time.
- (i)Only intervals with assays cut to 25 g/t gold are shown.
- Intervals are graded with a lower cut of 0.30 g/t with internal waste and
  low grade material within graded zones of up to 20 metres in length.

Trelawney 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 5 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.
