Tres-Or Commences Establishment of a Gold Resource at Its Advanced Duvay Gold Project, Quebec

VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 10/12/10 -- Tres-Or Resources Ltd. ('Tres-Or') (TSX VENTURE: TRS) is pleased to announce the completion of the first stage of field work at its advanced Duvay Gold Project in the Abitibi region of northwestern Quebec, preparatory to planning and initiating an evaluation program this fall. Tres-Or has an Agreement to acquire 100% interest in the Duvay property by staged expenditures and establishment of a gold resource compliant with National Instrument 43-101 (see Tres-Or news release dated May 25, 2010).

Gold was discovered on Tres-Or's Duvay property in the 1930s. Subsequent stripping, test pits, and drilling the 1940s, 1980s, and 1990s returned sample results and drill intervals including samples of up to 402 grams per tonne (g/t) gold (Au) over 0.36 m, 76.8 g/t Au over 0.46 m, 34.6 g/t Au over 0.43 m, 12.01 g/t Au over 1.53 m, 27.17 g/t Au over 1.14 m, and 16.598 g/t Au over 1.76 m from the Duvay property as reported in Quebec government mineral showing files (see news release dated September 30, 2010 for further details). Tres-Or cannot confirm these historic results due to the age of the reports, and thus has planned an exploration and evaluation program focused on drilling and small test pits for the fall of 2010, and extending into the winter of 2011.

This exploration and evaluation program is based on Tres-Or's recently completed field work comprising detailed structural mapping, a high-resolution ground magnetic survey and preliminary three dimensional (3D) modeling of the Duvay property. The structural mapping has identified intersecting compressional and extensional deformation zones in the heart of Tres-Or's Duvay property associated with historical high-grade sample results. These structural intersections are priority target areas for Tres-Or's planned drill and pit sample programs, in addition to two faults identified by both mapping and 3D magnetic modeling which cross the same area of high-grade gold samples.

Laura Lee Duffett, President and CEO of the Company, a qualified person by the standards of National Instrument 43-101, is overseeing the project and is responsible for the scientific and technical information in this news release.
