U3O8, a Canadian company focused on uranium exploration and resource expansion in South America, has reported significant uranium mineralization from scout drilling on the extensions of the Aricheng North structure in the Kurupung Batholith in basement rocks near the Roraima Basin in Guyana.
Five mineralized shoots have now been identified, increasing the mineralized trend at Aricheng North to 1.2km in length, and remaining open at depth and along strike. These new mineralized zones increase the resource potential at Aricheng North, which currently has an initial National Instrument 43- 101 (NI 43-101) resource of 2.1 million pounds U3O8 indicated and 0.5 million pounds U3O8 inferred.
The majority of the uranium at Aricheng North occurs within a northeast-trending shear zone breccia in the granodioritic Kurupung Batholith, and is located within an envelope of albite-chlorite-hematite alteration.
Bore hole ARN-101 is the first hole in which uranium mineralization was encountered in a shear zone in metasedimentary rocks outside of the batholith. The mineralized structure dips approximately 750 to the northwest, and varies in width from 1.5mt to 22mt.
Scout drilling has now extended the mineralized trend at Aricheng North to over 1.2km in length and from surface to approximately 190mt below surface. Mineralization at Aricheng North remains open at depth and along strike.
