Trelawney Intersects 356.00 Metres of 1.35 g/t Gold From Continued Expansion Drilling at Cote Lake

TORONTO, ONTARIO--(Marketwire - Aug. 29, 2011) - Trelawney Mining and Exploration Inc. (the "Company" or "Trelawney") (TSX VENTURE:TRR)(FRANKFURT:RTW) announces the results from 9 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 expansion and infill drilling on the Côté Lake Deposit. Drilling continues to intersect wide zones of low to moderate grade gold mineralization.

Highlights of the current drilling include:

  • Hole E11-72 – 30.0 metres of 0.92 g/t gold
  • Hole E11-74 – 126.00 metres of 0.82 g/t gold
  • Hole E11-76 – 91.00 metres of 1.41 g/t gold
  • Hole E11-77 – 303.00 metres of 1.27 g/t gold
  • Hole E11-78 – 356.00 metres of 1.35 g/t gold

Drill holes E11-77 and E11-78 are both located on section 88+00E, collared 85 metres apart and drilled south at ~47 degrees. This section is 100 metres west of the currently defined resource estimate. Updated sections and drill plan will be available shortly on the Company's website.

The inferred resource of the Côté Lake Deposit currently stands at 131 million tonnes grading 1.0 g/t for a total of 4.2 million ounces gold as reported in Trelawney's press release dated March 7, 2011. To date, mineralization of the Côté Lake Deposit has been intersected over a strike-length of 1,000 metres and outcrops at two known locations 500 metres apart. The zone remains open along strike 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 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. Mineralization occurs in the form of disseminated and fracture-controlled sulfides, 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.

The expansion and exploration drill program currently includes six drills working on the Côté Lake Deposit. Three drills continue with the expansion drilling and three are undertaking infill drilling.

Greg Gibson, Trelawney's President and CEO commented, "We are very pleased with the continued significant results of the step out drilling, and believe that this information will significantly expand the resource in our next estimate update. Definition drilling continues to be encouraging, with the current holes confirming original zones found in the wider spaced drilling. We will continue our aggressive exploration program and initial engineering studies to enable us to fast-track the development of this deposit."

Notes
True widths of intersections are unknown at this time

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.
