Trelawney Intersects 190.66 Metres of 1.88 g/t Gold on 100-Metre Step-Out at the Cote Lake Deposit
TORONTO, ONTARIO--(Marketwire - April 22, 2010) - Trelawney Mining and Exploration Inc. (the "Company") (TSX VENTURE:TRR) announces recent drill results from the new Cote Lake Deposit discovered on the Chester Project located halfway between Timmins and Sudbury in northern Ontario. Highlights of the drilling program include:
-- Hole E10-08 - 114.00 metres of 0.97 g/t gold
-- Hole E10-09 - 190.66 metres of 1.88 g/t gold
-- Hole E10-10 - 230.60 metres of 0.88 g/t gold
The results being reported are from the Cote Lake Deposit located about 1 kilometer southwest and along strike of the former Young Shannon gold mine (Chester 2 Deposit). The holes are all located on section 94+00E located 100m east of section 93+00E reported on March 3, 2010. The spacing between drill holes on each section varies from 50 to 75 metres.
The drilling program continues to identify wide zones of gold mineralization hosted within breccias. The host breccia and adjacent wall rock contain disseminated 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. Carbonate content in the breccia is quite limited (small rare veins). Structure associated with the gold mineralization is limited to brecciation with a lack of penetrative foliation.
A total of 22 holes have now been completed, covering sections 92+00 to 95+00E. Drilling continues to intersect alteration and lithological units of a type that seem to confirm the current hypothesis that the deposit is an Archean porphyry-like deposit. The main gold mineralization to date occurs within a brecciated diorite which appears to have undergone intense feldspathic alteration. Other breccia types that have been intersected are more chloritic with minor epidote locally possibly defining a propylitic-type alteration halo. Additionally, large units of white highly altered quartz-sericite +/- pyrite zones have been intersected that are currently regarded as a possible phyllic alteration zone. Visible gold has been noted in association with these new lithologies, however, assays have not yet been received. Silica flooding and carbonate alteration associated with more normal Archean greenstone mesothermal ores are absent or greatly diminished. The mineralization and alteration envelope associated with this system remains open along strike and to depth.
Drilling is currently on hold for spring break-up, however processing of the backlog of drill core continues. The spring- drill program will commence once ground conditions improve with the objective of expanding the mineralization associated with this new discovery.
Greg Gibson, Trelawney's President and CEO commented, "We are very encouraged by these current results from the Cote Lake area. The continuing wide widths of gold mineralization on this step-out section confirm our belief that this has the potential to develop into a large tonnage, open pitable gold deposit. Trelawney will continue to aggressively explore this new area to determine the extent, geometry and grade of mineralization. We look forward to reporting additional drill results to our shareholders on this new discovery. Trelawney is in a unique position of currently planning an advanced exploration program on the high grade underground project at the Chester 1 deposit less than four kilometres east of this new discovery."

A section of the four drill holes for which assays are reported is attached herewith and posted on Trelawney's website (www.trelawneymining.com).
Trelawney Mining and Exploration 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 g subset of each sample is pulverized to 90% passing -150 mesh. Assays have been completed using a standard fire assay with a 30 g aliquot and an AA finish. For samples that return values of between one 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.
David Beilhartz, Vice President, Exploration for Trelawney Mining and Exploration, a Qualified Person under NI 43-101, has prepared or supervised the scientific or technical information for the property and verified the data disclosed in this press release.
Trelawney is a Canadian junior mining and exploration company with a strategic focus on "Quality Ounce" gold deposits.
