Essakan Drilling Continues to Expand the Deposit - Intersections in new Lower Zone include 28m grading 3.6 g/t and 22m grading 4.6 g/t OTTAWA, May 19 /PRNewswire-FirstCall/ -- Orezone Resources Inc. (OZN:TSX, AMEX) is pleased to announce that drilling on the Company's Essakan gold project in Burkina Faso, West Africa continues to return significant results from both the Essakan Main Zone ("EMZ") and from mineralization that has recently been identified below the EMZ. Results from the Lower Zone include 28m grading 3.6 g/t in hole ERC1080D and 22m grading 4.6 g/t in hole ERC874D. Hole ERC1065D intersected mineralization below the EMZ at 170m and again at 220m indicating that there may be multiple zones at depth. Results from infill drilling within the EMZ included 36m grading 7.8 g/t in hole ERC882 and 23m grading 14.7 g/t in hole ERC894. These results are from an ongoing drill program with four rigs currently on site. Orezone and JV partner Gold Fields Limited ("GFL") have initiated a pre- feasibility study on the EMZ and are carrying out expansion drilling to increase the size of the deposit and infill drilling to increase the accuracy of the ore resource estimate. Expansion drilling is focussed on four areas; the Lower Zone, the down dip extension of the deposit, and on both the north and south ends of the deposit. Orezone and GFL recently announced a $US7.9 million budget increase to fund work through to the end of September, 2005. This will include US $2.9 million for the infill and expansion drilling and US $5.0 million to complete the pre-feasibility study. Ron Little, President of Orezone stated, "Our last resource estimate was completed in August, 2004 and over 80,000 meters of drilling has been completed since that time, including many higher grade intersections. A new resource estimate is scheduled for this July and will be based on results received to the end of April, 2005." He added that, "We intend to update resources again in the late fall in order to incorporate results from drilling between April and September, 2005." > Note: Samples were collected at a minimum of every 1m down the hole and analyzed using a 2kg bottle roll cyanide leach at the SGS Laboratory in Tarkwa, Ghana, an internationally recognized laboratory. A minimum of 5% of the samples are for QA/QC, which includes duplicates, triplicates, standards and blanks. The program was carried out under the supervision of Jeffrey Ackert, VP Exploration, and qualified person for Orezone. GFL can earn a 50 per cent interest in the Essakan Property by spending US $8 million over five years, and can increase its interest to 60 per cent by financing and completing a bankable feasibility study. GFL will surpass US $8 million in expenditures this month and has made Essakan one of its top priority exploration and development projects. Orezone is currently the operator of the joint venture.
