Sovereign Metals Ltd on Monday said it has received ‘outstanding’ results from purification testing of graphite at its Kasiya rutile-graphite project in Malawi. The Malawi-focused mine explorer and developer said testwork confirmed coarse flake graphite at the project could be purified to 99.95% using acid purification, and 99.98% using alkaline purification. ‘These are truly outstanding results - effectively achieving battery grade purities of +99% and less than 0.05% ash under conditions that typically result in under 1% ash,’ said Chief Executive Officer & Managing Director Frank Eagar. ‘For our future customers, this has the potential to significantly reduce reagent consumption and waste generation in the production of high-purity flake or targeted high-end applications.’ Shares in Sovereign Metals were up 2.7% at 45.20 pence in London on Monday morning. The stock has almost doubled from 23.50p over the past year. CEO Eagar continued: ‘This is yet further confirmation that Kasiya graphite concentrate is a premium graphite suitable for the anode, refractory, expandables and now also the high-purity powder metallurgy markets. We are delighted with the significant commercial optionality it brings to the Kasiya rutile and graphite project.’ Copyright 2025 Alliance News Ltd. All Rights Reserved.
