Orezone Confirms Mineralization at Bombore Below Surface Resources

OTTAWA, ONTARIO, Jun 24 (MARKET WIRE) --
Orezone Gold Corporation (TSX: ORE) is pleased to announce assay results
for the first seven out of twenty holes from the 4,500m diamond drilling
program being carried out on its wholly owned Bombore gold project in
Burkina Faso, West Africa. The purpose of the program is to investigate
the potential continuation of the surface oxide gold resources into the
fresh rock below a vertical depth of 55m and to identify the geological
controls of the gold mineralization. The Bombore Project contains 0.93
Million ounces of Indicated resources and 1.78 Million ounces of Inferred
resources with grades averaging approximately 0.5 g/t in the surface
oxide zone and closer to one gram of gold per tonne in the fresh rock
below.

Results to date indicate that there is a positive correlation between the
sulphide content (mostly pyrite) and the degree of deformation (shearing)
with the higher grade gold mineralization. The program is being carried
out in an area where the pit shell used to calculate resources is
approximately 1km wide. Holes have been spaced every 90m along two
section lines that are 200m apart. Initial results, along one drill
section, have confirmed the very wide, low grade nature of the near
surface oxide mineralization at the top of the recent drill holes are on
par with the oxide-ore resource model. At depth, below the core or centre
of the oxide resource, the results appear to indicate that mineralization
is more contrasted with alternating domains of higher grade and lower
mineralization 10's of metres wide. Better intersections included 41m at
1.08 g/t in hole BBD068 at 135m below surface and 43m at 1.06 g/t in hole
BBD069 at 75m below surface. These intersections are approximately double
the expected grade based on the surface resource model. The other holes
for which results have been received were drilled outside of the centre
or core domains and along the eastern fringe of the resource model. These
fringe results indicate a lower than expected grade based on the surface
oxide resource model. Table 1 shows results from the first seven holes
drilled on the Bombore property. Results from the second drill section
and the balance of the holes are expected to be released by the end of
July.

"Limited results to date indicate that Bombore is mineralized at depth
and the system remains open", said Ron Little, President and CEO of
Orezone. "More drilling and the metallurgical results expected in Q4 are
required to fully appreciate the economic potential of a deeper fresh
rock resource. Our goal at depth, based on recent results, is to focus on
the better grade domains that could be selectively mined and processed
rather than a wholesale approach of processing a larger but lower grade
resource, as expected at surface" he added.

The results to date are typical of such a large low grade system and only
represent a fraction of the 10km of strike length of the Bombore Project
resource model. Bombore has the potential to host a large, lower grade
open pit operation with very good infrastructure compared too much of
West Africa. It is located 80km east of the capital city of Ouagadougou
adjacent to a major national highway, and near a large water reservoir,
and will have access to an international power grid in the coming years.

Bombore Metallurgical Test Work Update: GBM Minerals Engineering
Consultants Limited has been contracted to supervise a metallurgical
testing program that will evaluate the potential for both heap leach and
conventional milling technologies, or a combination thereof, for
processing the Bombore deposit. The processing of the samples by Ammtec
laboratory in Perth, Western Australia, started at the end of May. If
heap leaching proves to be viable, Orezone will launch an RC expansion
drilling program to increase the oxide resources at surface. Similarly,
if grinding tests of the sulphide ore are positive, there is significant
potential to expand the resources at depth. Results of the metallurgical
tests are expected in Q4. In parallel with the metallurgical work, the
data gathering for the Bombore Baseline Environmental Study is
essentially completed and the final report is expected during Q3.

Drilling on the Bombore property was supervised by Dr. Pascal Marquis,
Vice President of Exploration for Orezone, who is a Qualified Person
under National Instrument 43-101 and has reviewed and approved the
technical information in this release. Orezone employs a rigorous Quality
Control Program (QCP) employing a minimum 10% standards, blanks and
duplicates. All core holes were entirely sampled; core split in half and
samples collected by Orezone approximately metre. The sample preparation
was performed by Abilab Burkina S.A.R.L., a subsidiary of ALS Chemex.
Assays were completed at BIGS Global Burkina S.A.R.L. for oxide and
transition material using the LeachWELL(TM) method and the fresh rock
material was analyzed by SGS Burkina S.A. using Fire Assay method.

Orezone is a gold exploration and development company that owns Bombore,
one of the largest gold deposits in Burkina Faso, West Africa. Orezone
also has a pipeline of developing projects, all located in politically
stable areas of West Africa, one of the world's fastest growing gold
producing regions. Orezone's mission is to create wealth by discovering
and developing the earth's resources in an efficient and responsible
manner.

FORWARD-LOOKING STATEMENTS AND FORWARD-LOOKING INFORMATION: This news
release contains certain "forward-looking statements" within the meaning
of applicable Canadian securities laws. Forward-looking statements and
forward-looking information are frequently characterized by words such as

"estimate" and other similar words, or statements that certain events or
conditions "may" or "will" occur. Forward-looking statements and
forward-looking information in this new release include statements with
respect to the scope and timing of the drilling project and metallurgical
testing for Bombore and the timing of the release of a resource update
for the Sega project.

Forward-looking statements are based on certain assumptions, opinions and
estimates of management at the date the statements are made, and are
subject to a variety of risks and uncertainties that could cause actual
events or results to differ materially from those projected in the
forward-looking statements. The assumptions include that contracted
parties provide goods and/or services on the agreed timeframes, that
equipment necessary for the drilling program is available as scheduled,
that no labour shortages or delays are incurred, that no material adverse
change occurs to Orezone. Factors that could cause the forward-looking
statements and forward-looking information to differ materially in
actuality include the failure of contracted parties to perform as
contracted and the failure of equipment. The Company undertakes no
obligation to update forward-looking statements if circumstances or
management's estimates or opinions should change. The reader is cautioned

Readers are advised that National Instrument 43-101 of the Canadian
Securities Administrators requires that each category of mineral reserves
and mineral resources be reported separately. Readers should refer to the
