Says it previously appointed Schoolenberg as interim chair on September 12. Notes that Schoolenberg has five years experience at Accsys, having been a senior independent director since 2018.

Atlantic Lithium Ltd - Sydney-based lithium exploration and development company, with assets in Ghana and Ivory Coast - Announces maiden JORC-compliant mineral resource estimate of 15.7 million tonnes at 40.2% feldspar for its Ewoyaa lithium project in Ghana. Says the estimate includes 13.7 million tonnes in the measured and indicated categories. Notes that the MRE covers the main, northeast, south-1 and south-2 deposits, which constitute the first five years of planned spodumene concentrate production at the site. Says the feldspar MRE will allow the possible inclusion of by-product credits in future studies, which it says are believed to drive down costs and add to the project's value. Feldspar is a by-product of spodumene production. Chair Neil Herbert says: "Identified early on by the Company as a by-product of spodumene concentrate production at Ewoyaa, the definition of the maiden Feldspar MRE now confirms the Project's potential as a major source of domestic feldspar in Ghana, capable of delivering industry-standard saleable ware. Currently supplied only by small-scale mining operations, we intend to supply the feldspar into the local Ghanian ceramics market. The feldspar MRE indicates Ewoyaa's potential to meet and even surpass Ghana's demand requirements, further demonstrating the significant contribution the Project is expected to bring to Ghana.
