Trelawney Intersects 137.00 Metres of 5.33 g/t Gold at the Cote Lake Deposit

Toronto, Ontario -- (Marketwire - Sept. 8, 2010) - Trelawney Mining and Exploration Inc. (the "Company") (TSX VENTURE: TRR) (FRANKFURT: RTW) announces additional drill results from the Cote Lake Deposit on the Chester Project located halfway between Timmins and Sudbury in northern Ontario. Highlights of the drilling program include:

•  Hole E10-26 – 292.04 metres of 0.88 g/t gold
•  Hole E10-27 – 137.00 metres of 5.33 g/t gold within a larger envelope of 274.60 metres of 2.99 g/t gold
•  Hole E10-04 extension – 17.90 metres of 8.06 g/t gold

The results being reported are from the recently discovered Cote Lake Deposit. The holes are located on several sections as noted in the table below. The mineralized intersections in holes E10-26 and E10-27 are located 100 metres apart on adjacent sections. Hole E10-27 is about 130 metres below previously reported hole E10-14 (1.62 g/t gold over 65.0 metres) and about 100 metres west and 50 metres below the previously reported high grade intersection in hole E10-04 (8.20 g/t gold over 107.11 metres).

To date Trelawney has drilled 34 holes totaling over 15,000 metres on the Cote Lake deposit. Of the 34 holes drilled, 27 have been reported on. Mineralization has now been intersected on five sections spaced 100 metres apart (92E to 96E) and traced to depths of up to 500 metres. On the most complete section, 93+00E, the mineralized envelope has a width of over 400 metres in section. The wide zones of low to moderate grade gold +/- copper mineralization are 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 and chloritic. The mineralization and alteration envelope associated with this system remains open to the north at depth, to the south and along strike.

The expansion and exploration drill program continues with two rigs defining the extent of the Cote Lake deposit and a third rig exploring other targets on the 1,700 hectares (4,200 acre) Chester Property. Trelawney surface crews have also commenced outcrop stripping and washing in the area of the Cote Lake discovery.

Greg Gibson, Trelawney's President and CEO commented, "We are very pleased with the success of this ongoing drill program and the exceptional results we have reported today. These large intervals of gold mineralization significantly expand the tonnage potential of this new deposit. We will continue to aggressively explore and expand Cote Lake while moving our high grade underground projects (Chester 1 and 2) forward."

Notes:
- True widths of intersections are unknown at this time
- * - Only intervals with assays cut to 50 g/t gold are shown
- Intervals are graded with a lower cut of 0.40 g/t with internal waste and low grade material within graded zones of up to 20 metres in length
- Sections are idealized with all holes projected onto the section they were collared on

A drill plan and sections of the drill holes for which assays are reported are posted on Trelawney's website (www.trelawneymining.com).

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.
