Trelawney Moving Ahead to Extract Bulk Sample From Dorset Property

TORONTO, ONTARIO--(Marketwire - May 15, 2009) - Trelawney Mining and Exploration Inc. (TSX VENTURE:TRR) announces that the Company is moving ahead with preparations to extract a bulk sample from the Dorset property, located near Wawa, Ontario. Planning for the operation began in March of this year and, currently, Trelawney management is focused on obtaining necessary permitting and securing a contractor for road construction and the mining of the bulk sample.

Standard preliminary laboratory bottle roll cyanidation, flotation, and an acid base accounting "ABA" test was completed on one small sample (approximately 16 lbs) collected from surface mineralization from the Dorset "B" zone. Testing determined that this sample is non acid generating and is refractory to cyanidation, with approximately 20% gold recovery. Bottle roll leach and "ABA" testing was completed by Process Research Associates, Richmond, B.C, and flotation testing was conducted by metallurgical consultant Mr. Gary Hawthorn, of Westcoast Mineral Testing Inc., Vancouver. As the sample size is small, it may not be representative of entire Dorset "B" zone mineralization, and no metallurgical testing has been completed on the Dorset "Main" zone. The Company is expecting that further metallurgical testing from the Dorset "Main" and "B" zones will be completed in June, prior to finalizing plans to extract a bulk sample.

On the Dorset property, Trelawney has earned a 50% interest in the project, and a joint venture has been formed with MetalCORP Limited. Trelawney is the manager of the Joint Venture.

Trelawney commissioned a National Instrument 43-101 compliant resource estimate on the Dorset Zone and the results were reported in a press release dated October 31, 2007. The initial estimate (using a 0.50 g Au/t cut off) consists of an Indicated Resource of 40,000 ounces of gold (780,000 tonnes grading 1.42 g/t Au) and an Inferred Resource of 180,000 ounces of gold (4,760,000 tonnes grading 1.19 g/t Au).The complete report can be accessed on www.sedar.com.

Trelawney also owns a 100% interest in the 13,000 acre Mishi property which is contiguous to Wesdome's producing Eagle River Gold Mine, the Dorset property and the Mishibishu Lake property. The area is traversed by an all weather road and power line.

Trelawney is the largest land holder in the entire mining camp with approximately 21,000 acres now under its control. The Company's neighbour, gold producing Wesdome Gold Mines Ltd. which holds approximately 16,000 acres. Trelawney has assembled the largest land package in this area since the Hemlo staking rush in the 1980s. The consolidated property contains over 48 known gold occurrences attesting to the potential of the Mishibishu greenstone belt.
