Kodal Minerals PLC (LON:KOD) said it has received initial test results from a bulk sample of pegmatite-hosted lithium mineralisation taken from the Bougouni lithium project in southern Mali.
The group said the recoveries from the Bougouni bulk sample rang in at up to 83%, to give a 5.5%-to-6% Li2O spodumene product. That is significantly higher than the 71% recovery used in Kodal Minerals' initial feasibility study and indicates upside on the project.
It also said the spodumene concentrate is low in impurities with iron content reported at below 0.5%.
The test work was completed by Shandong Shengli Environment Protection Technology Co Ltd, a company associated with Shandong Ruifu Lithium Co Ltd, at its Yishu plant in Shandong province, People's Republic of China.
The Yishui processing plant is a two million tonne per annum dense media separation and flotation plant, purpose-built for the concentration of spodumene mineralisation from pegmatite ore.
