Switch Metals (LSE:SWT) has completed the resource washing phase for the maiden Mineral Resource Estimate at its Issia tantalum project, finishing the fieldwork portion of the programme on schedule and within budget. Laboratory analysis and geological modelling are now underway, with the first resource estimate, MRE-1, expected to be delivered in the coming weeks by independent consultant Arethuse Geology.
The company intends to follow a staged approach to resource development. The initial MRE-1 will focus on eluvial and colluvial mineralisation, with subsequent updates—MRE-2 and MRE-3—planned to expand the estimate by incorporating additional tantalum-rich zones and alluvial drainage targets. Management considers the first resource estimate a significant step toward advancing technical and economic evaluations, progressing toward a future mining licence, and potentially establishing early-stage production. The project is also positioned to benefit from strong tantalum prices and growing demand for responsibly sourced, conflict-free supply.
