Orezone Bombore Gold Project Update

Drilling results indicate better than expected grades and continuity

Orezone Resources Inc. (OZN:TSX, AMEX) ) is pleased to announce the results of a recently completed 57 hole, 5,700m diamond drilling (DD) program on its Bombore Gold Project in Burkina Faso, West Africa. More than 13km of the mineralized trend was tested to a vertical depth of 75m with numerous holes ending in mineralization. The program was designed to test the continuity of the NI 43-101 resource model that contains 576,000 oz at 0.61 g/t of indicated resources and 501,000 oz at 0.66 g/t of inferred resources. All of the intersections from this program occurring within the current NI 43-101 resource model returned values that exceed those grades and widths indicated from the grade block model. Table 1 presents significant intercepts using a 0.4 g/t cutoff as per the initial resource estimate. Several intervals of more than 20m and 1.0 g/t were encountered in addition to numerous higher grade zones over 2.5 g/t.

In addition to better than expected grades and widths the new results demonstrate that at a slightly lower cut-off value (e.g., 0.2-0.3 g/t, which is typical of large low-grade bulk tonnage deposits) the continuity of mineralization is significantly increased. “The recent core program at Bombore has achieved two important objectives by demonstrating higher gold values and confirming the consistency of a larger lower grade envelope.” stated Steve King, V.P. Exploration for Orezone.

20,000m of Reverse Circulation (RC) drilling continues on the project in order to in-fill the resource model and expand resources. A preliminary metallurgical study is expected this quarter and a resource update by year end. A location map and more information are available on the Orezone website.
