TORONTO, ONTARIO--(Marketwire - Jan. 25, 2011) - Trelawney Mining and Exploration Inc. (the "Company" or "Trelawney") (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:
Expansion drilling of the Cote Lake deposit continues to intersect wide zones of low to moderate grade gold mineralization both at depth and along strike to the southwest. Hole E10-41 is an overcut of hole E10-40 on section 89+00E; hole E10-40 intersected 229.40 metres of 1.32 g/t gold (see press release of January 5, 2011). Holes E10-42 and E10-43 are undercuts on sections 95+00E and 94+00E, respectively, and continue to indicate that the mineralization remains open at depth on all sections that have been drilled.
The Cote 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.
Greg Gibson, Trelawney's President and CEO commented, "We are very pleased with the continuation of the mineralization to depth and to the southwest. To date the grades and size of the mineralized intervals encountered at relatively shallow depths in the Cote Lake Deposit continue to demonstrate the large size and open pit potential of the mineralized system."
The expansion and exploration drill program has resumed with four drills currently on site and a fifth planned to commence next week. The majority of the winter drilling will be on the wetlands southwest of the known mineralization. Additional geophysical work has been completed to the west and south of the deposit with results expected shortly. Work has commenced on the initial resource estimate and will be finalized within the first half of 2011.
Cote Lake Deposit Drilling Results:
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 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.
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 focus on Archean gold deposits. The Company's current focus is directed towards the development and continued exploration of the Chester Project, located in Chester Township 20 kilometres southwest of Gogama, Ontario.
