Sovereign Metals Ltd on Wednesday said it has completed major geotechnical field investigations at its Kasiya rutile-graphite project in Malawi, marking a significant milestone in its ongoing definitive feasibility study. The Malawi-focused mine explorer and developer said over 400 individual geotechnical tests were carried out across the proposed mine infrastructure, tailings storage facility and raw water dam sites. The work was completed under the supervision of the Sovereign-Rio Tinto technical committee and conducted by ARQ Geotech. Initial results showed favourable subsurface conditions aligned with regional geology, including consistent soil and rock profiles across project areas. These findings will support standardised foundation designs and reduce engineering complexity, Sovereign said. ‘Completing these comprehensive infield geotechnical programs marks another significant milestone towards the completion of our DFS,’ said Managing Director Frank Eagar. ‘This is another step in our systematic approach towards the development of Kasiya.’ The fieldwork included rotary core drilling, seismic analysis, cone penetration testing and auger drilling. Material collected will be used to inform final engineering and construction plans, contributing to what Sovereign called ‘safe, efficient and cost-effective development.’ Sovereign said the geotechnical data will be integrated into the detailed design of infrastructure and foundations, supporting continued progress of the feasibility study for what it describes as a ‘genuine Tier-1’ project. Shares in Sovereign Metals were down 1.9% at 36.80 pence in London on Wednesday afternoon. Copyright 2025 Alliance News Ltd. All Rights Reserved.
