The junior is now eyeing an initial 1.2 mln tonne a year processing plant, expanding to 1.5 mln tonnes pa as the operation moves into a steady production phase.
Recent assays contained lithium at grades between 1.2% and 1.7% at Sogola-Baoule and 1.04% at Boumou.
Assay results are pending for a further 2,732 samples with a mineral resource estimate update expected by the end of February.
Bernard Aylward, chief executive said the drilling at the end of last year had confirmed the continuity and robustness of the lithium mineralisation at Bougouni.
“This gives us great confidence as we continue to fast track our development plans for the Project.
“As such, we are in the process of completing a Mineral Resource estimate update that will include all drilling results to date as we look to confirm a long term mine life.
"The opportunity highlighted by these continuing good results is that we are now able to assess our proposed operation parameters and factor in a larger mining operation with an initial 1.2Mtpa processing plant, expanding to 1.5Mtpa as the operation moves into steady production phase.”
