Sovereign Metals Ltd (LSE:SVML) has secured a further investment of $690,360 from Rio Tinto, following the mining giant’s exercise of unlisted options to acquire over 1.29 million shares in the company. This additional funding increases Rio Tinto’s stake in Sovereign Metals to 19.9%, building on its initial $18.5 million investment made in July 2023. The investment is intended to support the advancement of the Kasiya rutile-graphite project in Malawi, a key focus for Sovereign Metals.
Kasiya stands as the largest known rutile deposit and the second-largest flake graphite resource globally. The investment by Rio Tinto not only provides financial backing but also includes technical and marketing expertise to further the development of this significant project.
Recently, Sovereign Metals announced that it has produced high-quality Coated Spherical Purified Graphite (CSPG) from Kasiya natural graphite feedstock. The performance of this graphite has been described as "outstanding," with characteristics comparable to the highest quality natural graphite battery materials produced by leading Chinese manufacturers. Electrochemical testing revealed impressive results, including first-cycle efficiencies ranging from 94.2% to 95.8%, excellent initial discharge capabilities above 360mAh/g, specific surface areas greater than or equal to 2.0m²/g, and tap densities between 1.11 and 1.18g/cm³.
In addition to these developments, Sovereign Metals has commenced a hydraulic mining trial at Kasiya to evaluate the effectiveness and environmental impact of high-pressure water techniques for large-scale operations. This trial, part of an ongoing optimization study, will be led by Fraser Alexander, a specialist in hydraulic mining, and follows the successful completion of a dry mining evaluation in July.
The progress at the Kasiya project highlights Sovereign Metals' commitment to advancing its flagship project, which is set to make significant contributions to the global supply of rutile and flake graphite.
