Castle Minerals Limited reported strong infill drilling at its Bundi prospect in Ghana, with multiple high-grade gold intercepts confirming mineralisation continuity and thickening at depth. Follow-up RC and auger drilling are planned to expand discoveries at the emerging Kpali Gold Project, enhancing its growth potential for investors.

Castle Minerals Limited has reported encouraging results from its recent reverse circulation drilling program at the Bundi prospect within the Kpali Gold Project in Ghana’s Upper West region. The five successfully drilled holes – with one planned hole postponed due to wet ground conditions – have all intersected gold mineralisation above a 1.00g/t cutoff. Notable intercepts include an 18‐metre section grading 1.22g/t gold, with 3 metres grading 3.35g/t and another 3 metres grading 1.77g/t from one hole. A second hole returned 7 metres at 3.26g/t gold, which encompassed 5 metres at 4.34g/t and an impressive 2 metres at 9.46g/t gold. The drilling results confirm continuity of mineralisation along strike and to depths of 100 metres or more, with evidence suggesting that the mineralised zones are thickening with depth. The company’s Executive Chairman, Stephen Stone, highlighted that these robust drilling results have strengthened Castle Minerals Limited’s confidence in the prospectivity of Bundi, just one of several promising targets within the broader Kpali Gold Project. The recent acquisition of high-resolution aeromagnetic survey data – secured at no cost from a previous explorer – is set to enhance targeting and inform upcoming campaigns. Auger drilling, scheduled to commence in early August, will further test existing prospects and generate new targets, while follow-up RC drilling is planned for later in the current quarter once seasonal weather conditions improve. The technical details provided in the announcement, including intercept lengths, gold grades, and drilling orientations, suggest a significant potential for expanding the gold endowment in an area with a geological setting similar to other renowned West African gold camps. Researchers have noted the distinctive magnetic anomaly and regional VTEM anomaly present at the Bundi prospect, and historical work in the region, combined with these new results, highlights the considerable exploration upside in Ghana’s emerging gold district. Bullish sentiment is supported by the strong assay results, successful infill drilling that confirms continuity and thickening mineralisation, and the strategic use of high-resolution geophysical data to refine exploration efforts. These factors could lead to high-grade discovery potential in an underexplored region with multiple analogous deposits nearby. Conversely, bearish concerns arise from some operational challenges, including the delayed drilling in wet conditions and the inherent risks associated with early-stage exploration projects. Overall, Castle Minerals Limited’s recent developments offer a balanced view—while significant growth opportunities exist, further drilling and analysis are essential to convert these encouraging results into a substantial resource.
