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.

Sun Summit Minerals: Advancing District-scale Gold and Copper Projects in British Columbia
Sun Summit Minerals (TSXV:SMN,OTCQB:SMREF) is a Canadian mineral exploration company advancing district-scale gold and copper projects in British Columbia. Its flagship JD Project, located in the prolific Toodoggone district, is the focus of an aggressive 5,000-meter drill program in 2025 targeting a potential multi-million-ounce epithermal gold-silver system.
With funding in place, a five-year exploration permit secured, and an on-site camp established, Sun Summit is executing a disciplined strategy to build scale, unlock resource value, and deliver returns to shareholders. Reinvigorated by a revamped leadership team and a refined vision, the company is leveraging high-grade, strategically located assets to drive long-term growth.
The JD and Theory projects cover over 25,000 hectares in the heart of British Columbia’s Toodoggone mining district, one of Canada’s most prospective regions for epithermal gold-silver and porphyry copper-gold systems. The district hosts several significant deposits, including Thesis Gold’s Ranch and Lawyers projects (4.7 Moz gold equivalent, ~C$250 million market cap), Centerra Gold’s Kemess underground development, and TDG Gold’s Shasta-Baker project. The area is well supported by infrastructure, including hydroelectric grid access, all-season roads, and the nearby Sturdee airstrip.

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.
