Kurupung district similar to "albitite-hosted" deposits worldwide
U3O8 Corp. has defined a new uranium resource in the Kurupung Batholith, in the basement near the Roraima Basin in Guyana – a promising uranium district in South America. To date, we have reported an initial NI 43-101 resource estimate on the first two albitite-related, basement-hosted targets and have a growing pipeline of other mineralized areas with the potential to significantly increase our resource base. U3O8 Corp. aims to show that the Kurupung could host a large uranium resource of comparable size to peer deposits elsewhere in the world.
Uranium in the Kurupung is geologically similar to a class of basement-hosted deposits worldwide known as “albitite-hosted” uranium, many of which contain resources in the 50 to 130 million pound range (Figure 1)1. Common features of these sizeable systems include:

Uranium in the Kurupung extends from ~10 metres below surface to at least 220 metres (maximum vertical depth drilled to date) Mineralization remains open at depth on all structures |
