Brighton Energy Makes Another Near-Surface Uranium Discovery in Niger

Mineralization occurs in the same rock formation that hosts the Madaouela deposit 21 km away

OTTAWA, ONTARIO -- (Marketwire - Dec. 7, 2011) - Orezone Gold Corporation (TSX: ORE) is pleased to announce another new uranium discovery in Niger, West Africa by it 67% owned subsidiary, Brighton Energy Limited (“Brighton“). Brighton completed a 19-hole, 1,566 m drill program (see map) in November on its 500 km2 Zéline 4 permit, located 25 km east of AREVA's open pit SOMAIR mine, which together with the COMINAK underground mine, have produced approximately 240 million pounds of uranium oxide (U3O8) since 1971.

The first target is in a wedge of the Carboniferous Guezouman Formation in the southeast portion of the permit. The Guezouman is also the host rock of the neighboring COMINAK mine and Madaouela deposit mineralization. Sixteen holes totaling 1,146 m were drilled on an 800 m by 800 m grid. All holes intercepted the Guezouman Formation. Fourteen holes intercepted a minimum of 100 ppm eU3O8 over 10 cm or more, with nine intercepting ≥200 ppm eU3O8, (Table 1).

Drill holes are vertical and true widths are very close to the drill length intervals. Complete results (>100 ppm and >200 ppm eU3O8) from all drill holes completed to date on Zéline 4 are available on the website. Cuttings were collected for each 1-m interval of the mud rotary boreholes and a detailed geological log and interpretation was established by ULC Afrique de l'Ouest. ULC also performed the down-hole logging of the radioactivity, resistivity and hole diameter using a GeoVista logging unit at a sampling rate of one reading per ten centimeters. This program was executed under the supervision of Pascal Marquis, SVP Exploration for Brighton and Orezone, who is a Qualified Person under National Instrument 43-101 and approved the technical information in this release.

One hole, Z4M0098, reached the contact between the Talak argillites and the older basement rocks at a depth of 305 m. The hole intercepted uranium mineralization in the basement, including 6.4 m at 120 ppm eU3O8. At a depth of 7 to 71 m, the average grade of the Guezouman above a lower cutoff of 100 ppm is 184 ppm eU3O8 with a thickness less than 1 m. Reduced mineralization was intercepted in all 14 holes at an average depth of 33 m with the best intercept in hole Z4M0110 grading 242 ppm eU3O8 over 1.2 m.

The second target tested was the Terada Formation and the potentially underlying Devonian sandstones, west of the Madaouela Fault, where three holes were drilled for a total of 420 m. All three holes were pushed to depth and intercepted the basement rocks below the Terada sandstones. Hole Z4M0115 intercepted uranium mineralization in the basement rocks in several intervals less than 1 m in length at an average grade of 109 ppm eU3O8. All 3 holes intersected at least 100 ppm eU3O8 over a minimum of 10 cm in the Terada Formation and on average 109 ppm eU3O8 over <1 m with the best intercept grading 114 ppm eU3O8 over 0.8 m in Z4M0116.

These new discoveries are shallow and largely associated with reduced rocks, making them potentially amenable to open pit mining and standard extractive processes.

“Of the 117 reconnaissance holes and 20,596 m drilled this year, Brighton has now made three new uranium discoveries on three of its permits,“ said Ron Little, CEO for Brighton and Orezone. “The similarity of the geology of these discoveries to nearby deposits, and the quality of the results from widely spaced drill holes, are indicative of further potential and warrant more drilling. The next phase of definition drilling will attempt to outline the thicker and higher grade paleo-channels that are characteristic of the ores of the neighboring operations.“

Brighton is a private company, owned 67% by Orezone, with the remaining interest held by private and institutional investors. The company has a well located 4000 km2 land package and a seasoned team of nationals to carry out its ongoing exploration programs. With analysts forecasting a fundamental shortage in uranium supply over the next decade, the stakeholders of Brighton and Orezone are well positioned to benefit from the recent exploration success.
