U3O8 Corp. Intersects Uranium in Phase 1 Drilling

U3O8 Corp. is pleased to announce positive results from the first two holes of its 16 hole Phase I, 2,400 meter drill program in the Aricheng Area, located in Permit Area A, Guyana, South America. The initial results are encouraging and confirm uranium mineralization identified by Cogema in the early 1980′s. Results of note are 10.5 meters of 0.09% (2.0 lbs. per tonne) U3O8 in hole ARN-07-001 and 7.5 meters of 0.13% ( 2.8 lbs. per tonne) U3O8 in hole ARN-07-002. Details of all drill results are presented in the Table 1.

The two holes were diamond drilled on the Aricheng North anomaly (please see Figure 1: Aricheng North Detailed Scintillometer Mapping Drill Hole Locations), one of three areas to be tested during the ongoing Phase 1 drill program, and are twins of previous Cogema holes. The historic results of the Cogema holes are unknown and not available anywhere in the public record. The Aricheng North anomaly is a northeast-trending shear zone with a known strike length of 1,400 meters. Uranium mineralization is associated with hematite-chlorite stained fracture and breccia zones that surround a chloritized mylonite shear within the Kurupung Granodiorite. Higher uranium values occur within a broader mineralized zone, up to 65 meters in hole ARN-07-001, consisting of silica, chlorite and hematite alteration.

Samples were delivered to the AMCE Labs sample preparation facility in Georgetown, Guyana and then shipped to Vancouver, Canada for analysis by ICP-MS hot 4 acid digestion.

The initial Phase I drilling program is focusing on the Aricheng North, Aricheng West, and Aricheng South areas, which are only three of 43 radioactive anomalies outlined by the airborne radiometric survey completed last year.

“We are pleased with the results of the first two confirmation holes, they clearly confirm economic concentrations of uranium are present in the basement rocks in Permit A.”, said Allan Ibbitson, President and Chief Executive Officer. “As the Phase 1 drill program proceeds, the Company will test several more anomalous zones and analyze the results. The drill results will provide the information necessary to prioritize and target the most promising areas to be drilled later this year in Phase 2 drilling. These results also suggest that uranium concentrations will be found within the basement of the nearby Roraima Basin within the Company’s Permit B”

Further analytical results for the ongoing drill program will be announced when they are available.

About U3O8 Corp

U3O8 Corp. is a Canadian junior mineral exploration company based in Toronto, Canada. Currently focused on uranium exploration in the Roraima Basin area of Guyana, South America, U3O8 Corp.’s primary business objective is to acquire, explore and develop uranium projects in the Americas.

The Company has exclusive uranium exploration rights in two permitted areas in the Roraima Basin area of Guyana. The Permit A property covers approximately 579,500 hectares. Permit B property covers approximately 750,900 hectares. This area is of particular interest as its unconformity type geological formation is very similar to the Athabasca region in Saskatchewan.

Potential quantity and grade is conceptual in nature. There has been insufficient exploration to define a mineral resource and it is uncertain if further exploration will result in the target being delineated as a mineral resource.
