Tumas (Palaeochannel) Project
The Tumas (Palaeochannel) Project (and its extension into the Tubas Palaeochannel) straddles EPLs 3496 and 3497 as per Project Locality Map. It contains secondary uranium mineralisation (carnotite in calcretes and gypcretes) hosted in some areas by shallow fluviatile sheetwash sands and gravels and in other areas, more deeply incised channels.
These shallow resources will likely be amenable to free dig mining with some drill and blast sections. Alternatively, surface miners could be used although the nature of the shallow resources implies relatively low cost mining for either mining option. Ore sourced from these deposits can effectively be upgraded, either by relatively simple scrubbing and attritioning followed by screening, or more elaborately with processes such as Marenica Energy's U-pgrade(TM) technology. The product from such beneficiation processes could be transported to an in-country existing uranium mine to be used as satellite feed. For the more basic beneficiation approach the product would require an existing alkali leach processing plant (such as the nearby Langer Heinrich uranium mine) however it is believed that the more sophisticated U-pgrade(TM) process offers the potential for acid leach processing (such as at the Rossing Uranium Mine or the soon to be commissioned Husab Mine) either offsite or importantly, even a standalone operation producing a saleable yellowcake product.
A standalone operation would require the addition of a comparatively small acid leach circuit and a conventional refining circuit to produce a saleable yellowcake product.
