Yorbeau Reports Excellent Results From Compilation and Re-Interpretation of Recent and Historical Drill Data

MONTREAL, QUEBEC--(Marketwire - Sept. 22, 2010) - Yorbeau Resources Inc. ("Yorbeau"') (TSX:YRB.A) is pleased to provide an update on the very interesting results being obtained from compilation and re-interpretation of recent and historical drill data. Compilation work continues to demonstrate the importance of the two gold zones discovered between the Augmitto and Astoria mines, the Cinderella and Lake Gamble zones and has also indicated that the Augmitto and Astoria mines have considerably more potential than previously inferred.

Augmitto Mine

Supplementary core logging is going exceptionally well and vertical sections spaced approximately 400 metres apart have been completed between 4800E (Augmitto shaft) and 8000E (Lac Gamble). Several strongly-supported drill targets have been identified from the results to date and a priority list of drill holes complete with the number of metres of drilling required is being compiled. Two items of interest stand out:

  1. Many of the historical drill holes at the Augmitto mine did not penetrate completely through the target Piché Group. In other cases, the footwall zone, which is now recognized as an important gold zone located structurally below the Piché Group, was not reached by many of the holes. An important conclusion from the compilation work is that the apparent gaps in continuity to the gold deposit at Augmitto may not be real but in part an artifact due to the limited number of holes that fully tested the primary target at Augmitto, which is the lower portion of the Piché Group.
  1. Information extracted from the data compilation and re-interpretation reinforces the concept that a major gold shoot of the Augmitto mine extends in a westerly plunge beneath the Augmitto shaft, as previously inferred from drill and mapping data near the surface. The down-plunge extent of the shoot has not been drilled below 400 m depth and is therefore a significant target that will be drilled during the next phase of drilling on the property.

Astoria Mine

The final report from an independent consulting geologist has now been received, which is a comparison of drill data and the actual production from the Astoria mine. Such an exercise will prove extremely valuable in future resource evaluations because it is equivalent to drilling a mineralized zone and then doing a bulk sampling and test mining of the zone.

The highlights of the report are:

  1. Diamond drilling data represent very well what can be mined from a structure like the Astoria A-West zone (footwall zone) in spite of the "nugget effect", less than ideal drill spacing, and other phenomena that can affect a mineralized structure;
  1. The mined vein above Level 7 splays and becomes multiple narrow veins with low grade wall rock between them. Surface holes penetrated 15-20 m true widths averaging 2-3 g/t Au. These zones might be mineable by underground bulk mining, thereby adding ounces to the resource;
  1. There is a limited nugget effect in the Aw zone (footwall zone) so that in this gold zone the grade based on drill data will closely reflect what can be expected of the mined grade before mining dilution. This may not be true of mineralized zones the Piché Group, which seems to have a stronger nugget effect;
  1. Analysis of the grade distribution in the mined area shows that the mined vein becomes wider, higher grade, and more coherent with depth. The average grade on Level 7 is about 6 g/t Au, but at Level 10 it is about 10 g/t. This work clearly demonstrates that the Astoria zone is open to depth and in fact is quite possibly better in width and grade than the mined area.

These results are very encouraging and demonstrate that the Augmitto and Astoria mines are open to depth and laterally, both to the east and west. Additional drilling is planned to test these targets and to bring the drill spacing at all four targets (Augmitto mine, Cinderella, Lake Gamble and Astoria mine) to the spacing needed for a 43-101 resource calculation.
