Castle Minerals (ASX:CDT) confirms depth and strike continuity at Kandia Gold Project

Castle Minerals Limited (ASX:CDT) has reported encouraging results from its latest reverse circulation (RC) drilling program at the Kandia Gold Project in Ghana’s Upper West region.

The drilling, which targeted the 4000 and 8000 zones, has confirmed the continuity of gold mineralisation to depths of at least 150 metres, strengthening the potential of this emerging multi deposit gold corridor.

In this Q&A, Castle Minerals Executive Chairman, Stephen Stone, discusses the significance of the results, what they mean for the Company’s broader exploration strategy, and what comes next for the Kandia Gold Project.

What do the latest RC drilling results at Kandia tell us about the project’s potential?

The recently completed RC drilling program has delivered results that confirm well defined zones of gold mineralisation at both the 4000 and 8000 zones, extending to depths of at least 150 metres.

Several strong intercepts were returned, including 5 metres at 1.00 grams per tonne gold from 173 metres, 5 metres at 1.39 grams per tonne gold from 155 metres, 1 metre at 9.91 grams per tonne gold from 50 metres, 6 metres at 1.68 grams per tonne gold from 74 metres and 2 metres at 4.15 grams per tonne gold from 38 metres.

“The Kandia RC drilling programme has confirmed mineralisation in well defined lodes with the host structure extending to 150m depth.”

These results demonstrate that Kandia is progressing beyond its early stage geochemical anomalies into a more cohesive gold corridor with multiple mineralised prospects.

Importantly, the mineralised structures remain open both down plunge and along strike, indicating significant potential for further extensions through future drilling.

Why are these drilling results significant for Castle Minerals and its shareholders?

These results are significant because they strengthen our understanding of the geology at Kandia and confirm that mineralisation continues with depth, which is key to assessing the project’s overall scale.

The drilling has shown that gold mineralisation is not confined to shallow levels but is present in well defined lodes along a 16 kilometre corridor.

“Kandia is transforming from shallow anomalism to a series of prospects that have good depth and strike continuity. This bodes well for Castle’s strategy of delineating a large, mineralised tonnage across multiple deposits on the 16km north-east trending Kandia corridor.”

From a shareholder perspective, this progress aligns with our strategy of systematically building a pipeline of shallow gold resources in Ghana’s Upper West region, an area with enormous exploration potential but limited historical exploration.

With nearby discoveries such as the 2.8 million ounce Black Volta Gold Project and the 5.1 million ounce Namdini deposit as examples, our work at Kandia puts Castle in a strong position to contribute meaningfully to the region’s next wave of gold development.

What are the next steps for the Kandia Gold Project following this round of drilling?

We are not standing still.

The next phase of work is already set, starting with a targeted auger geochemical sampling program in early August.

This will help us validate several existing and newly generated targets, particularly along the granite-metasediment contact, where our recent structural analysis has identified promising areas for follow up.

“A detailed structural analysis of the Kandia trend has identified new targets and enhanced understanding of key structural controls on gold distribution. We will apply this knowledge to the broader Kandia licence and across all of Castle’s Wa East tenure.”

Following the auger sampling, we plan to return with another round of RC drilling in September.

The goal of this program will be twofold: to expand the known mineralisation at the 4000 and 8000 zones and to test new high priority targets identified from our ongoing work.

This methodical approach ensures that every dollar we spend is strategically focused on building the potential resource base.

How does the geology at Kandia compare with other significant gold projects in West Africa?

The geological setting at Kandia is very favourable and typical of many of West Africa’s major gold deposits.

The project sits within Birimian age greenstone rocks, which host numerous multi million ounce gold mines across the region.

The mineralisation at Kandia is associated with metasediments along the contact of a large granite intrusion, which is exactly the kind of structural and geological environment that has delivered significant discoveries elsewhere in Ghana and neighbouring countries.

In fact, Kandia is positioned just south of the Black Volta Gold Project and shares similar geological characteristics with other significant deposits, including Namdini in Ghana and the Assafou deposit in Côte d’Ivoire.

This geological setting, combined with the underexplored nature of Ghana’s Upper West region, gives us considerable confidence in the potential for further discoveries as we advance our work.

What advantages does Castle Minerals have in developing Kandia compared to other explorers in the region?

Castle Minerals holds several strategic advantages.

Firstly, we have an established land position in Ghana’s Upper West, an area that remains largely untouched by modern exploration despite its favourable geology.

Secondly, we bring deep local knowledge and experience, particularly through my own prior involvement in discovering and delineating the nearby Black Volta Gold Project during my time with Azumah Resources.

We also benefit from holding 100% of the Kandia Project through our Ghanaian subsidiary, Carlie Mining Ltd.

The licence is fully owned, with no third-party encumbrances beyond the standard Ghanaian Government free carried interest.

This gives us operational flexibility and full control over how we advance exploration.

Finally, Kandia’s proximity to other emerging gold projects offers potential logistical advantages, including access to future infrastructure and development pathways.

“An auger geochemical sampling campaign will commence in early August to validate existing and new targets. Follow-up RC drilling to extend defined mineralisation and test new high-conviction targets is planned for September.”

Building value through systematic exploration

Castle Minerals remains committed to advancing the Kandia Gold Project through disciplined, step by step exploration that unlocks the value of this underexplored gold corridor.

With multiple prospects already emerging, new targets identified, and further drilling planned in the near term, the Company is well positioned to deliver steady progress for shareholders while helping to shape the future of gold exploration in Ghana’s Upper West region.
