Trelawney Uncovers New Exposure of Cote Lake Mineralization

TORONTO, ONTARIO--(Marketwire - July 27, 2011) - Trelawney Mining and Exploration Inc. (the "Company" or "Trelawney") (TSX VENTURE:TRR)(FRANKFURT:RTW) announces the discovery of a new outcrop exposure of the Côté Lake mineralization and the release of additional drill results from the Côté Lake Deposit on the Chester Project located halfway between Timmins and Sudbury in northern Ontario.

The new outcrop exposure of the Côté Lake Deposit is located 500 metres to the southwest of the previous surface outcrop which occurs on line 92+00E. The new exposure is located on line 87+00E, approximately 75 metres south of previously reported hole E11-53. The mineralization is found in an irregularly shaped, 12 metre by 16 metre outcrop which has been stripped and washed. The zone is highly sodic altered and mafic breccia fragments can clearly be observed in the highly altered matrix. Assays for 22 samples taken evenly spaced in a 2 metre grid pattern from this zone averaged 1.38 g/t gold with the highest sample returning 5.57 g/t gold. Additional exploration in this area is being completed, with several other highly altered outcrops stripped and washed with more sampling planned.

The expansion and infill drilling on the Côté Lake Deposit continues to intersect wide zones of low to moderate grade gold mineralization. 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.

Highlights of the current drilling include:

  • Hole E11-66 – 147.00 metres of 0.80 g/t gold
  • Hole E11-67 – 192.00 metres of 1.11 g/t gold
  • Hole E11-68 – 293.60 metres of 0.76 g/t gold
  • Hole E11-69 – 103.30 metres of 0.51 g/t gold
  • Hole E11-70 – 60.45 metres of 1.89 g/t gold
  • Hole E11-71 – 153.00 metres of 1.75 g/t gold

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. An additional drill is currently testing other historical occurrences on the property.

Greg Gibson, Trelawney's President and CEO commented, "The discovery of this new outcrop exposure of mineralization such a long distance away from the original outcrops opens up numerous new options for the future development of this resource and potentially reduces start up capital. 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.
- *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.
- Holes E11-70 and E11-71 were abandoned prior to the target depth and did not penetrate the entire mineralized section.

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.
