Tres-Or Samples High Values of Gold, Silver, Lead, Copper, and Zinc and Increases Claims Position at Its East Mac Property, Quebec

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Dec. 6, 2010) - Tres-Or Resources Ltd. ("Tres-Or") (TSX VENTURE:TRS) is exploring the East Mac Property ("East Mac") in Duverny Township comprising 10 mineral claims covering 570 hectares in the Abitibi region of northwestern Quebec. East Mac is located 7 km south Tres-Or's advanced Duvay Gold Project, and 9 km northeast of the town of Amos. Quartz veins carrying gold and silver were discovered on the property in the 1930s which led to construction of a shaft, according to reports filed with the Quebec government (GM 59252). Historic drill results filed with the Quebec government (GM 8204) report drill intersections of 1,481.9 grams per tonne (g/t) silver (Ag) and 2.4 g/t gold (Au) over 0.1 m and 12.3 g/t Au over 0.2 m. Tres-Or prospected, mapped and collected two samples near the site of the old shaft, which is now covered with a cement cap. These two samples returned high gold (Au), silver (Ag) and lead (Pb) concentrations, as well as anomalous copper (Cu) and zinc (Zn). For details refer to maps of the Duvay Gold Project and East Mac Property at:

The high concentrations in one of these samples (EMACLLD#1) are 10.5 g/t Au, 345 g/t Ag and 1.14% Pb (Table 1). This sample was taken from the dump pile near the old shaft. The second sample (EMACLLD#2) was collected from an outcropping quartz vein and returned 62 g/t Ag, along with anomalous values of the other metals. The samples were selected as "grab" samples to try and confirm mineralization within the shaft and surrounding area, but it should be noted that the samples referred to in this news release are selective by nature, and thus unlikely to represent average grades on the property.

Tres-Or cannot confirm the historical reports nor know true thickness of the mineralization, but the new results are consistent with high gold and silver concentrations previously reported from veins in the shaft.

Table 1: Tres-Or surface grab samples selected at East Mac from the dump near the old shaft and an exposed quartz vein near the shaft.

  Au Ag Cu Zn Pb
  g/tonne g/tonne % % %
EMACLLD#1 10.5 345 0.176 0.075 1.140
EMACLLD#2 0.032 62 0.001 0.015 0.222

The gold analyses reported above are by fire assay with a gravimetric finish (for those >1.5 g/t Au) or atomic absorption (AA) finish (for those <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 Au, Ag and Pb for samples which returned high values over the limits for trace geochem analyses.

Following the successful site visit to the East Mac shaft, Tres-Or has increased its claims holding in the area by purchasing the contiguous East Mac Sud property from Sementiou, Inc. ("Sementiou"). The combined East Mac and East Mac Sud properties comprise 45 claims and cover 2301 hectares in Duverny Township, near Amos. Tres-Or will pay to Sementiou a cash payment of $50,000 and complete $75,000 of approved exploration work within 36 months to earn a 76% interest in the East Mac Sud Property. Sementiou retains 24% and no royalty applies.

Tres-Or entered into a property option agreement (the "Option Agreement") dated December 21, 2009 with Sementiou, Inc. (the "Optionor") whereby the Optionor granted the Company the exclusive right to acquire up to an undivided 76% right, title and interest in 11 different groups of project claims, including the East Mac property, all located in the Abitibi-Temiscamingue region of northwestern Quebec (see news release dated January 21, 2010). Tres-Or is the project Operator.
