Drilling Significantly Expands Recently Discovered
Lower Zones at Essakan
Intersections
include 12.3 g/t over 13m and 4.1 g/t over 28m
Orezone Resources Inc. (OZN:TSX,
AMEX) is pleased to announce that drilling on the
Company's Essakan gold project in Burkina Faso, West Africa,
has significantly expanded the new zones of mineralization
that were recently identified in the footwall below the
Essakan Main Zone ("EMZ"). Results include 12.3
g/t over 13m in hole ERC0844D, 6.7 g/t over 13m
in hole ERC832D and 4.1 g/t over 28m in hole
ERC1076D.
The footwall mineralization
has now been intersected by more than 130 drill holes over a
strike length up to 1.5km, and from surface to a depth of
200m. The mineralization generally occurs from one to 20m
below the EMZ and its average thickness is in the order of
10m. The average grade of the footwall mineralization from
drilling done to date is higher than the average grade of
the EMZ. While this is encouraging, it may reflect the fact
that most of the drilling in the footwall is below the 1km
higher grade core of the EMZ. This positive correlation may
be indicative of the strength of the structure that produced
the higher grades within the deposit.
Orezone currently has two
reverse circulation ("RC") drill rigs and two core
rigs working on the EMZ. A total of 55,645m of RC and
10,529m of diamond core drilling have been completed since
the current drill program commenced in August, 2004 and a
further 17,000m of drilling is planned. The program includes
both infill drilling on 25m by 25m centres to increase the
percentage of resources in the measured and indicated
categories and expansion drilling to increase the total size
of the resource. The expansion drilling is targeting the
down dip extension and the western margin of the EMZ, strike
extensions to both the north and south, and the lower zones.
Over 20,000 samples from
Essakan are currently waiting to be assayed and encouraging
results are being received from approximately 7,000 new
samples being generated each month. As a result, the joint
ventures partners have made a decision to defer the planned
resource update until such time as more of this new data can
be incorporated into the calculation.
Ron Little, President of
Orezone stated that "The latest drilling results
continue to confirm our belief that the EMZ is significantly
larger than the current indicated resource of 2.4 million
ounces and inferred resource of 300,000 ounces (based on a
0.5 g/t cut off grade). These resources were calculated in
August, 2004 and almost 66,000m of drilling has been
completed since that time. Ongoing drilling continues to
extend the limits of the mineralization in the lower zones,
down dip, and along strike to both the north and
south."
