.TORONTO, ONTARIO--(Marketwire - Oct. 18, 2011) - Trelawney Mining and Exploration Inc. (the "Company" or "Trelawney") (TSX VENTURE:TRR)(FRANKFURT:RTW) announces the results from 10 additional holes drilled on the Côté Lake Deposit on the Chester Project located halfway between Timmins and Sudbury in Northern Ontario. The results are from the ongoing expansion and infill drilling on the Côté Lake Deposit. Drilling continues to intersect wide zones of low to moderate grade gold mineralization.

Highlights of the current drilling include:

• Hole E11-91 – 30.80 metres of 1.49 g/t gold
• Hole E11-92 – 57.25 metres of 1.57 g/t gold
• Hole E11-94 – 72.00 metres of 0.80 g/t gold
• Hole E11-95 – 1.00 metre of 85.58 g/t gold
• Hole E11-96 – 119.00 metres of 1.34 g/t gold and 126.60 metres of 1.52 g/t gold
• Hole E11-98 – 44.00 metres of 1.65 g/t gold
• Hole E11-99 – 421.60 metres of 0.82 g/t gold
• Hole E11-100 – 23.00 metres of 1.21 g/t gold and 54.00 metres of 1.05 g/t gold

Results for four infill and six exploration holes are being reported on today. Expansion drilling continues to intersect wide zones of mineralization to the southwest with hole E11-100 intersecting two zones on section 86+00E.

The infill holes have been drilled at various angles along the infill sections to provide better variography in the upcoming resource estimate. Several of the infill holes have encountered diabase dykes on the 50 metre infill sections resulting in some breaks in the continuity of the mineralization along the holes. These dykes, estimated to be approximately 20 metres wide, were not unexpected as they can be seen on the magnetic maps. Minor additional infill drilling may be required in the vicinity of these dykes to convert the resource in this area to the indicated category.

Additional exploration work has also been conducted on the second exposure of mineralization on section 87+00E that was previously reported. The size of this outcrop has been expanded by additional excavation and sampling. A total of 82 individual samples have been taken over a 20X20 metre outcrop based on a two-metre grid pattern. The samples averaged 2.31 g/t gold uncut and 1.77 g/t gold using a 25 g/t gold top-cut.

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. To date, mineralization of the Côté Lake Deposit has been intersected over a strike-length of 1,200 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. 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.

Greg Gibson, Trelawney's President and CEO commented, "The infill and expansion drilling has progressed very well over the summer with six drills. A significant amount of additional data continues to be acquired which will be incorporated into our upcoming resource estimate planned for late this year or early in 2012. We will continue our aggressive exploration program and initial engineering studies to enable us to fast-track the development of this deposit."

Côté Lake Deposit Drilling Results:

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.

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 continued exploration and development of the Côté Lake Deposit, located in Chester Township, 20 kilometres southwest of Gogama, Ontario.
