Trelawney Intersects 337.00 Metres of 0.94 g/t Gold at Cote Lake

TORONTO, ONTARIO--(Marketwire - June 20, 2011) - Trelawney Mining and Exploration Inc. (the "Company" or "Trelawney") (TSX VENTURE:TRR)(FRANKFURT:RTW) announces additional drill results from the Côté Lake Deposit on the Chester Project located halfway between Timmins and Sudbury in northern Ontario. Highlights of the current drilling include:

  • Hole E11-60 – 158.90 metres of 0.97 g/t gold
  • Hole E11-61 – 123.00 metres of 1.42 g/t gold
  • Hole E11-62 – 172.50 metres of 1.18 g/t gold
  • Hole E11-64 – 116.40 metres of 0.88 g/t gold
  • Hole E11-65 – 337.00 metres of 0.94 g/t gold

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 March 7, 2011 press release. The majority of the results released today are from holes located in the wetlands area which was the focus of the winter drill program and confirm or expand on this mineralization. Hole E11-62, located on section 86+00E is 300 metres to the southwest along strike of the inferred resource.

Mineralization of the Côté Lake Deposit has been intersected over a strike-length of 1,000 metres and 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. Results of the IP survey over the Côté Lake Deposit area suggest additional strike extensions of the mineralization are possible. Trelawney continues to follow the mineralization along this trend by diamond drilling.

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 on the Côté Lake Deposit has been expanded to include six drills. Currently, three drills continue with the expansion drilling and three have commenced infill drilling. An additional drill is currently testing other historical occurrences on the property.

Greg Gibson, Trelawney's President and CEO commented, "We continue to be encouraged with the results of the expansion drilling and our belief that our inferred resource can be significantly expanded. With the addition of more drills we are now accelerating our infill program. This should enable us to start upgrading the resource into the indicated category and allow us to rapidly move the project forward."

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 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.
