This ore is termed the “Primary Ore” and, based on limited preliminary testwork previously conducted in 2007 and 2008, appears to have low recovery in metallurgical bottle roll testwork.
Over the past six months several experienced metallurgists have visited the Letlhakane Uranium Project and examined the Primary Ore in drill core offering opinions on possible leaching methods.
At the same time considerable mineralogical work has been carried out by Dr Rob Bowell of SRK at the University of Cardiff Mineralogy Laboratory. Ongoing exploration has revealed that there are higher-grade zones within the Primary Ore that may be amenable to selective mining.
The combination of the above factors has given the Board of A-Cap Resources the confidence to renew testwork on the primary ore with a view to completing a full range of variability testwork to establish the best way to unlock the value in this 60Mlb resource.
About 60% of the Inferred Resource is classified as “Primary Ore” which, based on limited previous work, has metallurgical recoveries of up to 50%.
A-Cap Resources has requested Lycopodium to conduct a study into the metallurgy and possible treatment options for the Primary Ore.
The objective is to ascertain if the 60Mlbs of U3O8 in the primary ore can be economically recovered.
