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.
