Tsodilo Resources Ltd Advances in Multiple Strategic Collaborations - Botswana Institute for Technology Research & Innovation, University of Cape Town and Battelle Memorial Institute on Efforts to Advance Critical Minerals and Rare Earth Element Exploration

Preliminary studies confirm REE mineralization at Gcwihaba, but economic potential remains unproven.

What the company is saying

Tsodilo Resources Ltd. is highlighting technical progress at its 100%-owned Gcwihaba Metals Project in Botswana through collaborations with BITRI, the University of Cape Town, and Battelle Memorial Institute. The company emphasizes the completion of preliminary mineralogical and geochemical studies on four selected drill-core samples from the C27 skarn, with detailed reporting of rare earth and base metal concentrations. It frames these results as foundational scientific work, not as resource estimates or economic assessments, and stresses the collaborative and capacity-building aspects of its alliances, particularly with Botswana’s own research institutions. Chairman and CEO James M. Bruchs is quoted to reinforce the narrative of integrated progress across geology, mineralogy, and AI-driven exploration targeting. The announcement is careful to caveat that all findings are preliminary and not directly comparable to previously reported oxide-basis TREO intercepts, with further analytical and drilling work planned.

What the data suggests

The disclosed figures show that sample TREE-C27-6-119 returned the highest total rare earth elements plus yttrium (ΣREE+Y) at 1,794 ppm (0.18%), including 403 ppm of critical REEs. Across four samples, ΣREE+Y ranged from 85 to 1,794 ppm, all with strong light-REE enrichment. Base metal concentrations were modest: TREE-C27-2-103 contained 948 ppm copper (0.095%), 184 ppm cobalt (0.018%), and 251 ppm zinc as ZnO (0.025% ZnO), while TREE-C27-2-107 had 368 ppm chromium as Cr₂O₃ (0.037%). Silver was present in all samples at 4.8–11.5 ppm (0.0005–0.0012%). Mineralogical studies by UCT identified cerium-rich allanite as the principal REE host, comprising 26–27% by weight in the main mineralized zone but dropping below 0.2% in weakly mineralized sections, with sharp heterogeneity even within single intervals (26.6% vs 0.1% Ce-allanite in adjacent sections). Apatite never exceeded 2.8% in any section. Battelle’s AI model is operational for exploration targeting but is not a resource or economic estimate. All results are explicitly preliminary, derived from a small number of selected samples, and are not representative of broader mineralized intervals or directly comparable to prior oxide-basis intercepts.

Analysis

The announcement provides a detailed technical update on preliminary mineralogical and geochemical results from a small number of drill-core samples at the Gcwihaba Metals Project, as well as the completion of a first-stage AI model for exploration targeting. All realised claims are supported by specific sample data, analytical methods, and collaborative research milestones. Forward-looking statements are present but clearly framed as intentions for future drilling and analytical work, with no overstatement of economic potential or resource size. The company explicitly cautions that results are preliminary and not directly comparable to resource estimates, reducing the risk of narrative inflation. While the tone is positive and emphasizes collaboration and technical progress, there is no exaggeration of near-term commercial impact or economic value. The capital intensity flag is set due to the mention of planned follow-up drilling, which is inherently capital-intensive and long-dated in its potential returns. However, the language remains proportionate to the stage of exploration, and no hype is detected.

Risk flags

• ●The results are based on a very limited number of selected drill-core samples, which may not be representative of the broader mineralized system. This sampling bias limits the ability to extrapolate findings to a resource scale.
• ●All reported figures are preliminary and derived from geological studies, not assays or resource estimation protocols. The company explicitly states that these results are not directly comparable to previously reported oxide-basis TREO intercepts, increasing uncertainty about economic relevance.
• ●There is no disclosure of resource estimates, economic studies, or timelines for advancing to those stages, leaving the project's commercial viability and time to value highly uncertain.
• ●The planned follow-up drilling and further analytical work will require additional capital, and the company does not discuss funding, cost structure, or financial runway in this release.
• ●Reliance on external research alliances and AI modeling introduces execution risk, as the integration of these findings into actionable exploration targets is unproven at this stage.

Bottom line

Tsodilo Resources’ update provides detailed technical evidence of rare earth and base metal mineralization at the C27 skarn in Botswana, with the highest ΣREE+Y result at 1,794 ppm (0.18%) and notable concentrations of copper, cobalt, zinc, chromium, and silver. The mineralogical work confirms cerium-rich allanite as the main REE host, but also reveals sharp heterogeneity within mineralized zones. The AI model from Battelle is a tool for exploration targeting, not a resource estimate. All findings are preliminary, based on a small number of samples, and are not intended as economic or resource statements. The company is still at an early exploration stage, with no timeline or funding details for advancing to resource estimation or economic assessment. Investors should treat these results as scientific groundwork rather than evidence of near-term value. The key takeaway is that while technical progress is evident, the economic case for Gcwihaba remains unproven and long-dated, pending much larger-scale drilling and formal resource definition.

Announcement summary

(TSXV:TSD, OTCQB:TSDRF, FSE:TZO) Tsodilo Resources Ltd. provided an update on its strategic collaborative research alliances supporting critical minerals and rare earth element exploration at its 100% owned Gcwihaba Metals Project in Northwest Botswana. The company is working with the Botswana Institute for Technology Research & Innovation (BITRI), University of Cape Town (UCT), and Battelle Memorial Institute. BITRI completed a preliminary geochemical and mineralogical characterization of four selected drill-core samples from the C27 skarn at Gcwihaba, specifically TREE-C27-2-103 (147.10 m), TREE-C27-2-107 (159.50 m), TREE-C27-2-110 (165.65 m) from drillhole 1822C27_2, and TREE-C27-6-119 (159.80 m) from drillhole 1822C27_6. Analyses were performed using XRD, XRF, ICP-MS, and SEM-EDX at BITRI's Gaborone laboratories. Of the four samples, TREE-C27-6-119 returned the highest ΣREE+Y result: 1,794 ppm (0.18% on an elemental basis), including 403 ppm critical REEs (Nd+Pr+Dy+Tb+Eu+Y). Results across the four samples ranged from 85 to 1,794 ppm ΣREE+Y, all showing strong light-REE-enriched patterns. SEM-EDX imaging of TREE-C27-6-119 showed iron-associated Ce-La-Nd-rich inclusions within micro-fractured, weathered pyroxene, and XRD identified skarn mineralogies from near-pure magnetite to diopside-rich calc-silicate. Base and precious metals were present at trace levels: TREE-C27-2-103 returned peak copper (948 ppm; 0.095%) and cobalt (184 ppm; 0.018%) values, with zinc of 251 ppm as ZnO (0.025% ZnO), and TREE-C27-2-107 recorded chromium of 368 ppm as Cr₂O₃ (0.037%). Silver was detected in all four samples, ranging from 4.8 to 11.5 ppm (0.0005-0.0012%). UCT completed a preliminary mineralogical study of C27 drill core using micro-XRF and QEMSCAN, analyzing eleven sections from drillholes 1822C27_6 and 1822C27_2. Both techniques indicated that cerium-rich allanite (Ce-allanite) is the principal REE host, making up 26-27% by weight of minerals in the main zone of 1822C27_6 (161.1 m and 161.8 m), but below 0.2% in weakly mineralized sections. Apatite made up no more than 2.8% of any section analyzed. In two sections from the same one-meter interval, Ce-allanite content varied sharply: 26.6% and 0.1%. The rare earth minerals are heterogeneous at the centimeter scale. These findings will guide core logging and sampling in the upcoming planned drill program, with follow-up electron-microprobe, LA-ICP-MS, and oxygen-isotope work planned. The C27 skarn mineralogy is comparable to Bastnäs-type REE skarns of Sweden, the Sin Quyen copper mine in Vietnam, and gold-copper skarn systems of Yunnan, China. Battelle completed a first-stage artificial-intelligence model trained on Tsodilo's Gcwihaba exploration database, integrating drillhole geochemistry with regional gravity, magnetic, and electromagnetic survey data. The model is intended to support identification of REE-anomalous drillholes and performed comparably to a standard benchmark in internal testing, with performance expected to improve as more data are incorporated. Tsodilo intends to use the model's output to rank exploration target areas and identify additional areas for follow-up exploration and future drilling. James M. Bruchs, Chairman and CEO, commented that the collaborations are advancing the Gcwihaba exploration value chain and building in-country capability in Botswana. The results are preliminary findings from geological studies of a small number of selected drill-core samples and sections, presented for geological scientific context only, and are not directly comparable with previously reported oxide-basis TREO drill intercepts. The Battelle model is a research and exploration-ranking tool, not a drilling recommendation or economic assessment.
