Trelawney Intersects 10.69 g/t Gold Over 3.7 m in Chester 3 Zone

TORONTO, ONTARIO--(Marketwire - Feb. 22, 2010) - Trelawney Mining and Exploration Inc. (the "Company") (TSX VENTURE:TRR) announces the initial results from the diamond drilling program on the Chester 3 Zone of its Chester Property, Swayze Greenstone Belt, located between Timmins and Sudbury in northern Ontario. Trelawney is reporting on 4 of the 12 diamond drill holes currently completed on the Chester 3 Zone where drilling has confirmed the gold mineralization reported by previous operators. The Chester 3 Zone is located 1 km north of the Chester 1 Zone where the Company is preparing to de-water and carry out an advanced exploration program and 2.5 km east-northeast of and along strike with the Chester 2 Zone (see attached map).

Trelawney's drilling has intersected gold mineralization associated with quartz veining, along with pyrite and chalcopyrite sulfide mineralization within a sheared quartz diorite. This diorite is part of the larger granodiorite intrusive complex that hosts the majority of gold mineralization in the Chester township area. Trelawney's land package covers the majority of this intrusion. Several additional holes are planned on this zone. Significant results received to date from the Chester 3 Zone drilling program are provided in the following table.

Mr. Greg Gibson, Trelawney's President commented, "This drilling confirms the historical reports of gold mineralization in the Chester 3 Zone. Mineralization defined in this part of the property could easily be developed from the current ramp located at the Chester 1 Zone where we are in the final stages of permitting for an advanced exploration program. We are encouraged by the significant exploration results generated to date on both the Chester 3 gold vein targets and the Chester 2 SW Zone large tonnage targets."

Elsewhere on the property drilling continues on the Chester 2 SW Zone with a total of 10 drill holes completed to date. This drilling is designed to determine the geometry and extent of this new zone of mineralization. Additional assay results from this ongoing drilling program will be released as they become available to Trelawney. A third drill has been added to the Chester drilling program to aid in completing certain holes prior to spring break-up.

A map indicating the location of drilling and the main mineralized zones on the Chester Project is attached.

Trelawney has implemented a quality-control, quality assurance program to ensure best practice in the sampling and analysis of the drill core. Assays have been completed using a standard fire assay with a 30 g aliquot and an AA finish. Samples with assay results above 5.0 g/t are re-analyzed using a gravimetric finish. 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 of Exploration for Trelawney, a Qualified Person under National Instrument 43-101, has prepared or reviewed 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. The Company's current focus is directed towards the development and continued exploration of its newly acquired Chester Project, located in Chester Township 20 kilometres southwest of Gogama, Ontario.
