.TORONTO, ONTARIO--(Marketwire - Sept. 19, 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 E11-81 – 265.00 metres of 0.73 g/t gold
• Hole E11-82 – 86.00 metres of 0.91 g/t gold
• Hole E11-84 – 93.00 metres of 1.68 g/t gold
• Hole E11-86 – 1.00 metres of 158.25 g/t gold (4.62 oz/t Au)
• Hole E11-90 – 540.00 metres of 0.59 g/t gold

Drillhole E11-81 was collared on section 92+50E and drifted onto section 93+50E. Drilling on section 92+50E is being conducted in the opposite direction (330º Az) from most of the previous drilling on the deposit to aid in proving continuity of the mineralization in different orientations within the deposit. This hole appears to have confirmed the continuity of mineralization, but more importantly has extended the mineralization approximately 175 metres grid north below existing drilling on the adjacent sections. This additional mineralization occurs within a potential pit area.

Drill hole E11-82 was collared on a 100 metre step-out from previously released results, increasing the total known strike length of the deposit to over 1200 metres. The mineralization encountered in this hole does not line up with the main trend of the deposit and will require additional drilling to determine its relationship to the deposit.

Infill hole E11-90, drilled on section 93+50E at an inclination of 75 degrees, intersected mineralization down to a vertical depth of approximately 710 metres, the deepest intersection of mineralization to date.

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 1200 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, "We are very pleased with the continued results of the step out and infill drilling. This additional information 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."

• True widths of intersections are unknown at this time.
• *Only intervals with assays cut to 25 g/t gold are shown.
• Intervals are graded with a lower cut of 0.30 g/t with internal waste and low grade material within graded zones of up to 20 metres in length.

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.
