Yorbeau Intercepts 10.99 Grams Gold Per Tonne Over 8.5 M (0.322 Ounces Gold Per Ton Over 27.88 Feet) in Drilling on the Augmitto Block

MONTREAL, QUEBEC--(Marketwire - Nov. 22, 2007) - Yorbeau Resources Inc. (TSX:YRB.A) is pleased to provide the following update on its 2007-2008 drilling program which is being carried out on the Augmitto, Cinderella, and Lac Gamble Blocks of the Company's Rouyn Property. The results are from the first phase of a minimum of 5,000 meters definition drilling on the Augmitto Block intended to validate gold grades. The data generated during this definition drilling campaign are currently being integrated into our exploration 3D model and geological interpretation is underway.

Hole 07-S-442, located on the most promising section 5300E has returned a weighted average grade of 10.99 g/t Au over 8.5 meters along core axis (4.5 m true width) at a core depth of 29.0 to 37.5 meters. Another mineralized section was intersected at a shallower core depth, from 17 m to 18 m at an average weighted grade of 7.95 g/t over 1 m along core axis. Visible gold is observed in quartz-carbonate-tourmaline veinlets in carbonatized and silicified ultramafic rocks (green carbonate ore) at a core depth of 34.20 m (40 tiny specks) and 36.40 m (2 specks).

"During 2007, the Company drilled more than 5,700 meters in 38 holes, of which many have encountered potential ore grades and widths, and abundant visible gold such as in hole 07-S-422. Of particular note are the shallow depths at which these high grades are being encountered. This high success rate is very encouraging and bodes very well for the 2008 program. A drilling exploration campaign consisting of 10,000 meters will continue in 2008 to target new gold structures and to demonstrate continuity laterally and at depth of the mineralized zones comprising the Augmitto historical resources", said Dr. Thomas L. Robyn, President and CEO of Yorbeau.

(i) Length along core axis


Hole 07-S-442 is 50 m West of section 5350E along which hole 07-S-425 returned the highest grade intersection to date from the definition drilling program (20.78 g/t Au over 3 meters or 1.9 m true width). Other high grade gold intersections have been previously reported in core from drill holes located along the same section as hole 07-S-425, which are: hole 07-S-426 (10.77 g/t over 4.1 m along core axis), and hole 07-S-424 (5.02 g/t over 8.5 m along core axis).

A zone of tectonic breccia was identified in the high grade gold zone of the carbonate ore in hole 07-S-442 at a core depth of 33.95 m. Disseminated sulfides (pyrite, arsenopyrite and minor chalcopyrite) are locally observed in the mineralized zone. It is important to note that the same tectonic breccia was also intersected in hole 07-S-421 at a core depth from 9.5 to 9.8 meters and in hole 07-S-422 at a core depth from 78 to 79.74 meters. Previously reported assay results indicate that the best mineralized intersection in hole 07-S-421 was observed at a core depth from 18.0 to 24.7 meters at a weighted Au grade of 14.00 g/t over 6.7 m along core axis. In hole 07-S-422, the most promising intersection was observed at a core depth from 90.0 to 96.3 meters at a weighted Au grade of 4.65 g/t over 6.3 m along core axis.

To date 31 definition holes totalling 3,960 meters holes have been drilled on the Augmitto block. In addition, 7 exploration holes totalling 1,779 meters have been drilled on the Cinderella block to test the Eastern extension of the Augmitto gold zones at shallow depth (maximum 300 m). Gold assay results are pending for definition drill holes 07-S-443 to 449 and exploration drill holes 07-S-450 to 456. A location map is available on the Company's web site.

The qualified persons under National Instrument 43-101 are Thomas L. Robyn Ph.D., CPG, RPG, Louis R. Bernier P.Geo., Ph.D. and Paul Blanchet, P.Eng. Samples were analyzed at Laboratoire Expert at Rouyn-Noranda, Quebec. Mineralized core samples are analyzed by fire assay method and reanalyzed by fire assay + gravimetry when they returned more than 3 g/t Au whereas core samples with visible gold are systematically analyzed by metallics sieve method. Samples having more than 3 g/t Au that were not analysed using the metallics method are being re-analyzed by another laboratory.
