Commenting on the drill results, Gladiator’s Chairman Greg Johnson said:
“The ISR assessment by ERM highlights the opportunity to develop Likuyu North. The geological and hydrogeological characteristics of the deposit appear to be ideally suited to ISR which can support significantly stronger project economics than is possible with conventional mining methods. That the deposit is close to the advanced stage Mkuju River Project operated by Uranium One provides optionality. We are optimistic that Likuyu North can deliver robust economics in today’s uranium market which is expected to strengthen further. We look forward to planning the next stage of work”.
The In Situ Recovery (ISR) Mining method
ISR (also known as ISL) accounts for over 50% of the world’s uranium production1, all from sandstone hosted deposits such as Likuyu North. It involves the drilling of injection wells and production wells (or recovery wells) within the uranium deposit. The leaching solution (or lixiviant) is injected to react with the ore, dissolving the uranium. The uranium-bearing solution, known as the pregnant solution, is then brought to the surface for treatment and recovery of uranium.
