Yorbeau Commences Drilling with Two Rigs

MONTREAL, QUEBEC, May 27 (MARKET WIRE) --
Yorbeau Resources, Inc. ("Yorbeau") (TSX: YRB.A) is pleased to report
that it has initiated drilling on the Cinderella East target of its Rouyn
property. Two diamond drill rigs are operating to extend the zone of high
grade gold mineralization discovered in this area during the Company's
2008 drilling campaign, which was penetrated by drill holes 08-CI-464 and
08-CI-467 (see press releases of September 25, 2008 and January 20, 2009).

The Company discovered this new zone in the fall of 2008 about 700 metres
east of the historic Cinderella prospect. In order to distinguish between
the two zones, management has decided to re-name the new zone, referred
to in previous releases as the Cinderella target, as the Cinderella East
target. The spatial relationships of the two zones are shown on the
accompanying long section.

In 2008, with 17,000 meters of drilling, Yorbeau discovered two new zones
of high grade gold mineralization in the Cinderella and Lac Gamble areas
that lie between the Astoria and Augmitto deposits along approximately 5
km of largely unexplored ground. Management has decided to initiate the
2009 program on Cinderella East because of the intensity of alteration
and mineralization (hole 464 returned 8.1 g/t gold over 7.0 meters core
length and hole 467 returned 27.3 g/t gold over 4.8 meters core length)
observed in drill core from this area. Another factor is that the Piche
Group is thicker and less deformed in this area, which is important for
the preservation of gold deposits that may have formed in this area.
