Yorbeau Reports Excellent Metallurgical Test Results and Provides Update on Exploration Activities on its Rouyn Property

MONTREAL, QUEBEC--(Marketwire - Aug. 24, 2010) - Yorbeau Resources, Inc. ("Yorbeau"')(TSX:YRB.A) is pleased to provide an update on exploration activities at its 100% owned Rouyn property. The Rouyn property straddles a 12-km-long section of the Cadillac-Larder Lake Break (CLLB) which is regional structure known to control several world class gold mines, including the 10 Moz Kerr Addison mine to the west and Osisko's 6.2 Moz Canadian Malartic project to the east.

The first phase of the 2010 drilling program was completed in June and the Company has since undertaken a comprehensive program of review and detailed interpretation of all new and historic drilling data, including at the past producing Astoria mine and the Augmitto project. This review involves re-examination and re-sampling of many historic drill core from the Augmitto mine which has already yielded new significant gold intercepts. The ultimate outcome of this review program will be to have a reliable interpretation of gold bearing envelopes for resource evaluation, and specific targets for the next phase of the drilling program. 

Company has also hired an independant professional geologist to fully review historic production data at the Astoria "A-West Zone" deposit on its Rouyn Property and to compare the actual production within this block with what could have been predicted from the drilling data. This exercise will provide critical data to assess the significance of our current drilling data for purposes of calculating potential mining reserves and will prove useful for the forthcoming NI 43-101 resource evaluation. The review is nearly complete and we are waiting for the final report.

The Company has also received new metallurgical test results from samples of drill core taken from the Lake Gamble zone of the Rouyn Property. The tests were conducted by Unité de recherche et de service en technologie minérale ("URSTM") of Rouyn-Noranda. These newly-tested samples were composited drill samples from two holes that penetrated the gold-bearing Piché Group. The composite samples, YB-1 & YB-2, were submitted to a combination of gravity and cyanidation recovery methods. According to URSTM Yorbeau samples YB-1 and YB-2 may be considered as easy milling gold ore. Gold recoveries are typical of non-problematic Abitibi gold ore and recoveries ranging up to 97% were obtained, including significant recoverable free gold. Chemical consumptions were found to be low and standard for this type of ore. 

The results of the metallurgical testing recently completed by URSTM plus the historical results indicate that gold-bearing rock from both the Piché Group and the footwall zone (Aw zone of Astoria) contains abundant free milling gold and that recoveries of gold during commercial mineral processing can be expected to be in the range of 90-95%. Blending rock from the sulphide-poor and carbonate-bearing Piché Group with the sulphidic footwall-type rock during mineral processing could also have a very positive effect on the environmental aspects of the resulting tailings.

The Company plans to continue with its compilation program and will report on progress as warranted.
