Gold bars to be exempt from tariffs, White House clarifies
MALAWI - Sovereign Metals Limited (ASX:SVM; AIM:SVML; OTCQX:SVMLF) announced Wednesday the completion of comprehensive geotechnical investigations at its Kasiya Rutile Graphite Project in Malawi as part of its ongoing Definitive Feasibility Study (DFS).
The company conducted over 400 individual tests across critical infrastructure locations including mining operations, process plants, tailings storage facility, and raw water storage dam. The fieldwork employed multiple investigation techniques such as rotary core drilling, cone penetration testing, and dynamic probe super heavy testing.
Preliminary findings indicate favorable subsurface conditions aligned with regional geology, showing consistent stratigraphy across the project area. The company noted this consistency could enable more standardized foundation designs and construction approaches, potentially reducing engineering complexity.
"Completing these comprehensive infield geotechnical programs marks another significant milestone towards the completion of our DFS and another step in our systematic approach towards the development of Kasiya," said Frank Eagar, Managing Director and CEO, according to the press release.
The geotechnical programs were conducted by ARQ Geotech (Pty) Ltd with oversight from the Sovereign-Rio Tinto Technical Committee. The collected data will inform detailed engineering design and infrastructure planning for the project.
The company reported that ferricrete identified within the transported horizon has been assessed as potentially reusable as engineered fill material, which could provide additional construction benefits.
The investigations revealed a subsurface profile typically consisting of surface topsoil, underlying transported horizon, reworked residual gneiss transitioning to residual gneiss with depth, and a deeply weathered soil profile that transitions to rock at greater depths.
The findings from these investigations will be integrated into the ongoing DFS work to optimize infrastructure placement and construction methodologies.
