Can Bundi’s Expanding Gold Mineralisation Deliver a New West African Mining Camp?
Castle Minerals reports strong gold intersections and expanding mineralisation at its Bundi prospect within the Kpali Gold Project, signalling promising exploration progress in northern Ghana.
- All five recent RC drill holes intersected gold mineralisation above 1g/t Au
- Notable high-grade intercepts include 7m at 3.26g/t Au and 2m at 9.46g/t Au
- Mineralised zones confirmed to extend and thicken at depth beyond 100m
- Acquisition of high-resolution aeromagnetic data enhances targeting capabilities
- Auger drilling to commence in August 2025 with follow-up RC drilling planned
Exploration Momentum Builds at Bundi
Castle Minerals Limited has delivered encouraging results from its recent reverse circulation (RC) drilling campaign at the Bundi prospect, part of the broader Kpali Gold Project in Ghana’s Upper West Region. The five-hole programme successfully intersected gold mineralisation exceeding 1 gram per tonne (g/t) in every hole, with some intervals revealing notably higher grades. These findings not only confirm the continuity of mineralisation along strike but also suggest that the gold-bearing zones thicken with depth, extending beyond 100 metres below surface.
High-Grade Intercepts Highlight Potential
Among the standout results are intercepts such as 7 metres at 3.26g/t Au, including 2 metres at an impressive 9.46g/t Au, and an 18-metre zone averaging 1.22g/t Au. These grades are significant in the context of early-stage exploration and bolster confidence in the prospect’s potential to host economically viable mineralisation. The drilling also revealed sulphide mineralisation and quartz veining typical of orogenic gold deposits, which are common in West Africa’s prolific Birimian greenstone belts.
Strategic Acquisition of Aeromagnetic Data
Adding to the exploration toolkit, Castle Minerals has secured a high-resolution aeromagnetic survey dataset from a previous explorer at no cost. This extensive survey, covering the Kpali Gold Project area, is being reprocessed with modern software to refine geological interpretations and improve targeting accuracy. The integration of this data with existing VTEM, ground magnetics, and geochemical datasets is expected to sharpen the focus of upcoming drilling campaigns.
Next Steps, Auger and Follow-Up Drilling
Looking ahead, Castle plans to commence auger drilling in early August 2025, aiming to extend known prospects and identify new targets within the project area. This will be followed by a more comprehensive RC drilling programme scheduled for the September quarter, designed to infill and expand the current mineralisation footprint. These activities are poised to deepen understanding of the project’s geology and resource potential.
Context Within a Growing West African Gold District
The Kpali Gold Project sits at the convergence of two major greenstone belts and several regional structural trends, a geological setting analogous to other significant gold discoveries in West Africa. Nearby projects such as the Namdini and Black Volta deposits in Ghana, and the Assafou discovery in Côte d’Ivoire, underscore the region’s emerging status as a fertile ground for new gold camps. Castle’s ongoing exploration efforts at Bundi and adjacent prospects contribute to this narrative, positioning the company as a notable player in the region’s gold exploration landscape.
Bottom Line?
Castle Minerals’ latest drilling and data acquisition at Bundi set the stage for a pivotal exploration phase that could redefine northern Ghana’s gold potential.
Questions in the middle?
- How will the new aeromagnetic data reshape targeting and drilling priorities at Kpali?
- What are the implications of mineralisation thickening at depth for potential resource size?
- When might Castle Minerals release a maiden resource estimate for Bundi or the broader project?
