Issia Project - Tantalum Resource Programme Update

Switch Metals confirms 54% coltan mineralisation over 1.35 km²; assays and drilling results pending.

What the company is saying

Switch Metals is highlighting the completion of systematic pitting across 2.5 km² of the Badinikro permit, with preliminary on-site XRF screening indicating coltan mineralisation over 1.35 km², or 54% of the MRE-1 target area. The company frames these results as validation of its exploration targeting, especially where the highest-grade zones (+10 g/t coltan in soils) coincide with pegmatite outcrops. Management repeatedly references the scale of the programme and the systematic approach, emphasizing the potential for both shallow placer and hard-rock tantalum resources. The narrative stresses the upcoming infill pitting at tighter spacing and the submission of priority samples for independent laboratory assay, with a promise of updates as results are received. CEO Karl Akueson positions the project as having significant upside, both from the current shallow mineralisation and from ongoing hard-rock exploration at Zraty and Kabore. The tone is optimistic, with repeated references to 'robust' resource classification and the broader potential of the Issia project.

What the data suggests

The company has completed a 2.5 km² pitting programme on a 100m x 100m grid, with preliminary XRF screening showing coltan mineralisation at grades above 4 g/t in soils across 54% of the area, equivalent to a 1.35 km² mineralised footprint. The highest-grade soil samples exceed 10 g/t coltan and are spatially associated with pegmatite outcrops, suggesting potential for both alluvial and hard-rock resources. An additional 1.3 km² (MRE-2) has also been sampled, bringing the combined tested area to 3.8 km², with plans to expand work to a further 7 km² of adjacent alluvial targets. No laboratory assay results or JORC-compliant resource figures have been disclosed; all grade data is preliminary and derived from on-site XRF analysis. Infill pitting at 50m x 50m and 25m x 25m spacing is planned but not yet complete. RC drilling at Zraty and Kabore is underway, with results expected soon. The disclosure is operationally detailed but remains at the pre-resource, pre-assay stage, with all economic and resource estimates still pending.

Analysis

The announcement is upbeat, highlighting completion of systematic pitting and preliminary XRF results, but the majority of key claims are forward-looking: infill pitting, laboratory assays, and integration of datasets for a maiden resource estimate are all planned or in progress, not realised. While the operational progress (pitting, XRF screening) is specific and supported by numerical data, there is no disclosure of financial metrics, resource tonnage, or grades beyond preliminary soil results. The language inflates the signal by referencing 'robust JORC-compliant categorisation', 'hard rock upside potential', and 'significant additional potential', none of which are substantiated by completed assays or resource estimates. The benefits (JORC resource, project scale) are long-term and contingent on future work. No large capital outlay is disclosed, but the scale of the programme implies ongoing spend with no immediate earnings impact. Overall, the narrative is moderately ahead of the evidence, with most value-driving milestones still to come.

Risk flags

• ●Resource definition risk is high: all mineralisation figures are based on preliminary XRF screening, not laboratory assays or JORC-compliant estimates. If lab assays or tighter-spaced pitting deliver lower grades or continuity than suggested by XRF, the scale and quality of the resource could be materially downgraded.
• ●Execution risk remains: infill pitting at 50m x 50m and 25m x 25m spacing, as well as laboratory assays and RC drilling, are all pending. Delays, technical issues, or disappointing results from these next steps could slow progress or reduce project attractiveness.
• ●Economic viability is untested: no cost, recovery, or economic data has been disclosed, and the company has not provided any preliminary resource tonnage or grade estimates. Without these, the commercial potential of the project is still speculative.
• ●Forward-looking statements dominate: the announcement relies heavily on future milestones and aspirational language about 'robust' resource classification and 'significant additional potential', none of which are yet substantiated by independent data.

Bottom line

Switch Metals has confirmed preliminary coltan mineralisation across 54% of its initial 2.5 km² target, with XRF soil grades above 4 g/t and local highs above 10 g/t, but all results are pre-assay and not yet JORC-compliant. The company is expanding its exploration footprint, with 3.8 km² now sampled and plans to test an additional 7 km², while also progressing hard-rock drilling at Zraty and Kabore. No laboratory assay results, resource estimates, or economic data have been disclosed, so the investment case rests on the successful conversion of these early-stage indications into a compliant resource. The next key catalysts are laboratory assay results and the maiden resource estimate, both of which are likely several months away. Investors should focus on assay confirmation and the scale of any JORC resource before assigning value. The most important takeaway is that while the footprint and grades are promising, the project remains at a high-risk, pre-resource stage with all value-driving data still to come.

Announcement summary

(AIM: SWT) Switch Metals plc has provided an update on its Issia Project Tantalum Resource Programme in Côte d'Ivoire, reporting completion of a pitting programme across approximately 2.5 km² of the Badinikro permit area on a 100m x 100m grid, representing the MRE-1 target area. Preliminary on-site XRF analyser screening results confirm large envelopes of coltan mineralisation within the MRE-1 target area, with a surface footprint covering 1.35 km², or 54% of this first target area. The highest-grade zones, with +10 g/t coltan grades in soils, overlay pegmatite outcrops. Infill pitting at 50m x 50m and 25m x 25m spacing is planned to further define the resource model and support robust JORC-compliant categorisation. Priority samples have been submitted to an independent laboratory for assay, and results are being progressed. The MRE-2 pitting and sampling programme has also been completed on an additional 1.3 km², complementing MRE-1 for a combined 3.8 km², with work set to progress across approximately 7 km² of adjacent alluvial drainage basin targets. The company continues to advance its hard-rock exploration programme at Zraty and Kabore, with RC drilling results for these pegmatites expected in the near term. Switch Metals is also assessing the potential to incorporate expanded datasets from shallow tantalum programmes and hard-rock drilling into an updated Exploration Target and broader resource model for Issia.
