- Immediate high-level objective is to confirm robust new West African mining camps at Kpali and Kandia and an initial 1.0Moz Au multi-prospect based mineral resource.
Castle Executive Chairman, Stephen Stone, commented “The Kpali Gold Prospect is developing into a robust discovery and is a strong indicator that we may be dealing with a new West African gold mining camp in Ghana’s emerging northern region.
The latest intercepts include some very decent widths and grades at shallow depths with good continuity which can have considerable positive impacts should mining be considered.
Fig 1: Kpali Gold Prospect: Plan showing latest drill results and outline of interpreted multiple mineralised sub-parallel lodes on simplified sub-surface geology.
We have intersected a very impressive 12m at 8.29g/t Au from 25m, including 6m at 11.60g/t Au from 31m and a peak 1m intercept of 20.43g/t Au at 36m in a ‘hangingwall’ lode, and also 4m at 4.16g/t Au from 95m in a lower ‘footwall’ lode.
Apart from these standout results, very strong mineralisation has been encountered within most holes drilled, implying that with additional drilling we may be able to delineate a decent high value deposit.
We are very keen to get back drilling and to extend the Kpali Gold Prospect discovery as well as to follow-up historical drilling at the nearby Bundi discovery, 4km north.
There are also several other enticing prospects in the broader Kpali Gold Project area.
These drilling results follow excellent recent results from four holes at the Kandia Prospect, a second and separate gold discovery associated with a relatively under- explored 16km prospective contact between Birimian metasediments and a granite intrusion. Recent intercepts at Kandia included 7m at 3.36g/t Au from 149m within 24m at 1.78g/t Au from 139m and 5m at 3.49g/t Au from 82m within 11m at 2.26g/t Au from 79m.
These deposits lie in a classic setting for major gold deposits in West Africa and in particular northern Ghana which hosts the Cardinal Resources 5.1Moz gold Namdini deposit and the Azumah Resources 2.8Moz gold Black Volta Gold Project. The latter’s high-grade Julie deposit is immediately along strike from Kandia.
West Africa is where big gold discoveries can be and are still being made. With the gold price now at a level I could only dream of when starting my career, it’s the perfect time to be exploring Castle’s two new discoveries in the very stable, safe and mining friendly jurisdiction of Ghana.”
Fig 2: North-south long-section through mineralised hangingwall and footwall lodes at Kpali highlighting zones of shallow plunging, high-grade gold mineralisation.
Additional intercepts included 7m at 2.23g/t Au from 35m(24KPRC011) including 11m at 2.24g/t Au from 50m, 5m at 3.6g/t Au from 78m (24KPRC012), 9m at 4.81g/t Au from 107m (24KPRC015) and 3m at 3.08g/t Au from 78m (KPRC017).
These results confirm the Kpali Gold Prospect, just one of several prospects within the broader Kpali Gold Project, as a robust discovery in a completely new district within Ghana’s emerging Northern Region exploration frontier.
With several other high conviction prospects yet to be evaluated in the area, including the nearby Bundi, Kpali East, Wa South East and Wa South West prospects, there appears to be present all the hallmarks of a new West African mining camp and the possibility of a considerable gold endowment.
The Kpali Gold Prospect lies within a mineralised corridor associated with a 30m to 50m wide zone of structural deformation immediately west of a granite intrusion. Three drilling programmes have identified near-surface, shallow plunging high-grade lode-style mineralisation to a depth of at least 100m. Multiple, closely-spaced mineralised lodes have been identified over at least 650m strike.
Overall, the geological setting at the broader Kpali Gold Project is of typically structurally-controlled, orogenic style mineralisation within Birimian terrane. This is a similar setting as that hosting several world- class gold mining operations in Ghana and West Africa generally. Orebodies with these characteristics can often extend to considerable depth.

Key Projects
Kpali Gold Project
The Kpali gold project, a cornerstone of Castle Minerals' exploration efforts, is strategically located approximately 30 kilometers west of the regional town of Sawla in Ghana's Upper West region. Encompassing the Kpali and Bundi prospects, along with several satellite discoveries, the project area lies within the 170 sq km Degbiwu prospecting license (PL 10/26), which is encircled by the 1,033 sq km Gbiniyiri retention license (RL 8/27). Notably, the western boundaries of these licenses are delineated by the Black Volta River, marking the border with Burkina Faso.
Geologically, Kpali is situated at the convergence of two significant greenstone belts — the Bole-Bolgatanga and Wa-Lawra/Boromo belts — and three regional-scale structures. This unique positioning is associated with several major Birimian-hosted gold deposits in the region, enhancing the project's potential for substantial gold mineralization.
Recent exploration activities have yielded promising results. In February 2025, an eight-hole reverse circulation (RC) drilling program intersected shallow, high-grade mineralization in all holes. Notable intercepts include 12 meters at 8.29 grams per ton (g/t) gold from 25 meters, including 6 meters at 11.60 g/t gold from 31 meters, with a peak 1-meter intercept of 20.43 g/t gold at 36 meters. These findings have significantly upgraded the status of the Kpali gold prospect, suggesting the presence of multiple sub-parallel lodes with high-grade gold mineralization.
The broader district encompassing Kpali contains several other high-conviction prospects, reinforcing its potential as an emerging new exploration frontier. Castle Minerals plans to undertake further drilling programs, including step-out drilling, to delineate the extent of mineralization and assess the project's viability for future development.
In summary, the Kpali Gold Project's strategic location, favorable geology, and recent high-grade drilling results position it as a significant asset within Castle Minerals' portfolio, with the potential to evolve into a major gold production site in Ghana.
Kandia Gold Project
The Kandia gold project is situated in Ghana's Upper West Region. Discovered in 2010 during reconnaissance field mapping, the project encompasses a 16-kilometer-long corridor along a significant granite-sediment contact within Birimian greenstone terrain. This geological setting is known for hosting substantial gold mineralization, with the Kandia prospect itself identified through previously unknown artisanal workings spread over approximately 600 meters of strike.
Initial exploration efforts included extensive soil sampling, airborne geophysical surveys and RC drilling, totaling 264 holes over 19,541 meters. These activities led to the identification of two primary mineralized zones: the "4,000 Zone" and the "8,000 Zone."
Strategically, the Kandia project benefits from its proximity to major gold deposits. The 5.1-million-ounce Namdini gold project lies to the northeast on the same Bole-Bolgatanga greenstone belt, while the 2.8-million-ounce Black Volta gold project's Julie deposit is immediately along strike from the Kandia mineralized trend. This favorable location enhances Kandia's economic attractiveness and potential for development synergies.
Future exploration plans for Kandia involve extensional drilling at the "4,000 Zone" and targeted drilling in other areas with historically wide-spaced shallow drilling, such as the "8,000 Zone," where artisanal mining activities are also present. The primary objective is to delineate multiple near-surface, open-pitable deposits along the 16-kilometer prospective contact, advancing the project toward potential development.

Key Projects
JD & Theory Projects
The JD & Theory projects span more than 25,000 hectares in the heart of the Toodoggone mining district in north-central BC, one of Canada’s most prospective belts for epithermal gold-silver and porphyry copper-gold systems. The district is home to Thesis Gold’s Ranch and Lawyers deposits (4.7 Moz gold equivalent, C$250 million market cap), Centerra’s Kemess underground development, and TDG Gold’s Shasta-Baker project. Infrastructure around the project includes hydroelectric grid access, the nearby Sturdee airstrip and all-season roads.
The JD project hosts a 4.5 km mineralized corridor, known as Creek-Finn, with multiple underexplored targets showing evidence of both high-grade veins and broad disseminated gold systems. Historic and recent drill highlights include:
- 2.1 grams per ton (g/t) gold over 122.5 m including 121 g/t gold over 1.5 m (CZ-24-004)
- 11.7 g/t gold over 22 m including 61.2 g/t gold over 4 m (CZ97-008)
- 7.3 g/t gold over 35.7 m including 215.4 g/t gold over 1 m (JD95-0472)
The Creek Zone features high-grade epithermal veins within broader disseminated zones, supported by strong IP anomalies and gold-in-soil results up to 12.2 g/t gold. The Finn Zone hosts near-surface mineralization with extensive historical drilling (~270 holes) and is open in all directions. Other targets include McClair (porphyry copper), East McClair (copper-gold skarn) and Moosehorn.
The 2025 program includes 5,000 meters of core drilling across 25 holes, 20 km of IP geophysics, 2,000+ soil samples, and full-scale camp operations. A five-year permit secured in April 2025 provides exploration continuity through 2030.
Camp setup at JD project
Sun Summit can earn 100 percent of the JD project by making staged cash/share payments and completing work commitments through 2029. With ~C$6 million earmarked for the project this year alone, Sun Summit is expected to fulfill its 2025 and 2026 earn-in obligations without additional equity raises.
Buck Project
The 100 percent owned Buck project spans 52,000 hectares and is located near key deposits, including Artemis Gold’s Blackwater (8 Moz gold), Imperial’s Huckleberry copper mine, and Newmont’s historic Equity Silver mine. Buck features near-surface bulk-tonnage gold-silver mineralization with porphyry copper-molybdenum potential at depth.
In February 2025, Sun Summit published its inaugural NI 43-101 mineral resource:
- Indicated: 1.15 Mt @ 0.519 g/t gold equivalent (19,100 oz)
- Inferred: 52.2 Mt @ 0.489 g/t gold equivalent (820,400 oz)
Mineralization remains open in all directions. Buck is considered a strategic asset providing leverage to rising gold prices and future transaction potential, but currently receives minimal capital allocation as JD is prioritized.
