Kandia Drilling Extends Gold Mineralisation to 150m Depth with High-Grade Hits
Castle Minerals’ recent drilling at the Kandia Gold Project in Ghana reveals well-defined gold mineralisation extending to 150 metres depth, underpinning a promising multi-deposit corridor. Follow-up exploration is set to expand these findings across the prospective Wa East tenure.
- 11-hole RC drilling confirms mineralisation continuity to 150m depth
- Multiple gold intercepts with grades up to 9.91g/t Au identified
- Structural analysis reveals new undrilled targets along granite-metasediment contact
- Auger geochemical sampling planned for August 2025, with further RC drilling in September
- Kandia forms part of Castle’s extensive, under-explored Wa East tenure in Ghana
Drilling Success at Kandia
Castle Minerals Limited (ASX, CDT) has reported encouraging results from its latest reverse circulation (RC) drilling campaign at the Kandia Gold Project in Ghana’s Upper West region. The 11-hole, 1,510-metre programme targeted the 4000 and 8000 zones along a 16-kilometre northeast-trending structural corridor, confirming well-defined gold mineralisation extending to at least 150 metres below surface.
Notable intercepts include 5 metres at 1.00 grams per tonne (g/t) gold from 173 metres and a standout 1 metre at 9.91 g/t gold from 50 metres depth. These results reinforce the presence of persistent mineralised lodes within the granite-metasediment contact zone, a geological setting known to host significant gold deposits in West Africa.
Structural Insights and New Targets
Beyond confirming depth continuity, Castle’s detailed structural review has identified multiple undrilled targets along the granite-metasediment boundary. This enhanced geological understanding is pivotal for guiding future exploration efforts, as it highlights key controls on gold distribution and potential extensions of mineralisation both along strike and down-plunge.
Executive Chairman Stephen Stone emphasised that Kandia is evolving from shallow anomalous zones into a cohesive corridor of multiple deposits with promising depth and strike continuity. This aligns with Castle’s broader strategy to delineate a large mineralised tonnage across its Wa East tenure, which remains largely under-explored.
Next Steps in Exploration
Castle plans to commence an auger geochemical sampling campaign in early August 2025 to validate existing targets and identify new ones. This will be followed by a further round of RC drilling scheduled for September, aimed at extending known mineralisation and testing high-conviction structural targets.
The proximity of Kandia to the 2.8 million ounce Black Volta Gold Project and other significant regional discoveries such as the 5.1 million ounce Namdini Gold Project underscores the potential for substantial resource growth. Castle’s methodical approach, combining geochemical sampling, structural analysis, and targeted drilling, positions it well to capitalize on this emerging gold corridor.
Regional Context and Outlook
Ghana’s Upper West region is increasingly recognised as a new frontier for gold exploration, with Birimian-age greenstone belts hosting many recent multi-million-ounce discoveries. Castle’s Kandia project benefits from this geological setting and the nearby infrastructure of operating mines, which could facilitate future development.
While the current drilling results are promising, the company cautions that further work is required to define mineral resources and assess economic viability. Nonetheless, the continuity of mineralisation and identification of multiple targets provide a strong foundation for ongoing exploration and potential resource expansion.
Bottom Line?
Castle Minerals’ Kandia drilling results mark a significant step in defining a multi-deposit gold corridor, with upcoming sampling and drilling poised to unlock further value.
Questions in the middle?
- Will follow-up drilling confirm the extent and grade continuity of the newly identified targets?
- How might the proximity to established projects like Black Volta influence development timelines?
- What are the implications of the structural controls for potential resource size and mining methods?
