Tres-Or Resources Ltd. Samples High Values of Gold, Silver and Copper at Its Advanced Duvay Gold Project, Quebec

Vancouver, British Columbia -- (Marketwire) -- 12/01/10 -- Tres-Or Resources Ltd. ('Tres-Or') (TSX VENTURE: TRS) is pleased to report results of eighteen (18) selected surface samples collected during structural mapping at its advanced Duvay Gold Project in the Abitibi region of northwestern Quebec. These samples have returned high gold (Au), silver (Ag) and copper (Cu) concentrations, as well as significant zinc (Zn).

The highest gold concentrations in these samples are 199 grams per tonne (g/t) Au, 130 g/t Au and 3.01 g/t Au (Table 1).

In the other 15 samples, gold values ranged between detection limit and 1.20 g/t Au. In addition, the sample with the most gold (at 199 g/t Au) also carried 4.55% Cu, as well as greater than 100 g/t Ag. Other samples returned between detection limits and 1.31% Cu, and up to 45.8 g/t Ag, as well as 1.61% Zn.

All gold analyses reported above are by fire assay with a gravimetric finish (for those greater than 1.5 g/t Au) or atomic absorption (AA) finish (for those less than 1.5 g/t Au). The Tres-Or sample analyses were completed at Activation Laboratories Ltd. ('Actlabs') in Ancaster, Ontario which is an independent ISO rated facility for mineral analyses. The samples were first analyzed for 59 trace elements by aqua regia digestion and mass spectrometry (AR-MS) at Actlabs. The same lab then completed assays for Ag, Cu, and Zn for samples which returned high values over the limits for trace geochem analyses.

The samples were selected outcrop samples collected to confirm mineralization during structural mapping. Samples yielding greater than 1.0 g/t gold were collected over a 500 m strike length, including both shear zones and quartz veins. Note that the samples referred to in this news release are surface chip and hand (grab) samples, which are selective by nature, and thus unlikely to represent average grades on the property. However, these new samples confirm Au, Ag and Cu mineralization occurs over the central area of the Duvay Gold Project in both compressional shear zones and extensional quartz veins.

The high gold concentrations from the Tres-Or samples compare well with historical results 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 drilling in the 1940s through the 1980s, as reported in Quebec government mineral showing files (see news release dated September 30, 2010 for further details). Tres-Or cannot confirm the historical drill results, but the new Tres-Or surface sample results are consistent with such high gold concentrations from drill core.

No previous Ag, Cu, or Zn results have been reported from the Duvay Gold Project.

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).

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.
