Bannerman Resources Limited (ASX:BMN) announced that their Etango Membrane Study has been completed successfully, delivering substantial reagent/operating cost reductions along with forecast capital savings, the final quantum of which is to be confirmed in the Etango Definitive Feasibility Study Update.
Highlights are as follows:
Nano-filtration delivers substantial potential cost savings
- Over 80% of acid recovered, reducing largest reagent cost
- Corresponding decrease in acid-neutralisation chemical volumes
- Potential capital savings through reduction in downstream equipment size
Membrane Study demonstrates nano-filtration benefits to Etango
- Confirmed recovery of acid for re-use
- Uranium solution upgraded almost ten-fold
- Confirmed residual deleterious elements can be efficiently removed before uranium precipitation
Confirms Ion Exchange (IX) with nano-filtration (NF) favourable over Solvent Extraction (SX)
- Enables IX/NF process to replace SX in DFS Update
- Both economic and operational advantages in the IX/NF process route
- Membrane Study provides valuable process input in DFS Update
Brandon Munro, CEO, commented:
The amenability of the Etango Project to recent advances in established nano-filtration technology is an exciting outcome that further confirms the robust economics and low technical risk of the Etango project. Our technical team undertook the Membrane Study diligently and comprehensively, utilising the unique advantages Bannerman’s Heap Leach Demonstration Plant offers, in particular the access to industrial-scale uranium bearing solution generated from the Etango orebody. I am delighted that this success further enhances Etango, both economically and operationally, as a world-class, highly-advanced and strategically important uranium project.
