Castle Minerals Limited (“Castle” or the “Company”) advises that a recently completed eight-hole, 1,106m RC drill programme at its Kpali Gold Prospect in Ghana’s Upper West Region (“Project”, “Kpali”) has intersected mineralisation in all holes including 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 an interpreted ‘hangingwall’ lode and then 4m at 4.16g/t Au from 95m in a lower “footwall” lode (24KPRC010).
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.”

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.

Castle Minerals is a compelling investment opportunity, underlined by its 100 percent ownership of two high-potential gold projects, a seasoned management team with a track record of success, and a strategic location near multi-million-ounce gold deposits.
Castle Minerals (ASX:CDT) is an Australia-based exploration company dedicated to advancing high-value gold projects in Ghana, West Africa. The company holds a 100 percent interest in a highly strategic 2,686 sq. km land package within Ghana’s Upper West region, a significantly under-explored yet highly prospective geological setting within the West African gold belt.
Castle Minerals’ core mission is to identify, explore and develop economically viable gold deposits, leveraging the region’s rich mineralization and proven mining history. The company's management team brings extensive experience and a strong track record of successful discoveries, ensuring that exploration efforts are guided by industry-leading expertise and strategic execution.
Castle’s portfolio is centered around its flagship Kpali and Kandia gold projects, both of which exhibit strong potential for resource expansion and economic development. These projects are situated within prolific gold-bearing structures and have demonstrated high-grade mineralization through extensive exploration efforts. With a focus on systematic exploration, the company aims to delineate and expand resources while positioning itself as a leading player in Ghana’s growing gold industry. Castle’s commitment to sustainable exploration practices and strong community engagement further enhances its ability to operate effectively in the region.
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.
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.

North Bay Resources, Inc. (the " Company " or " North Bay ") (OTC: NBRI) is pleased to announce delivery of 344 lbs. of gold concentrate to the Company's refinery partner Just Refiners, Reno, NV. Assay splits have been sent to ALS Geochemistry Reno, Nevada. Ore from the Company's Fran Gold Project was processed at the Company's Bishop Gold Mill. The concentrate represents approximately 15 tons of gross ore processed. Recent repairs to the Company's RakerClassifier and replacement of balls in the ball mill have been implemented to produce a finer grind targeting minus 150 mesh. This grind has been determined to be optimal for recovery. The concentrate is from the gravity only circuit with the flotation circuit currently under optimization and testing ( See Pic 1) . The Company recently received settlement on its first concentrate shipment ( see Press Release dated April 7, 2025 ),
Pic 1. Bishop Gold Mill Flotation Cells.
Flotation Circuit
The Company is testing and optimizing the flotation circuit at the Bishop Gold Mill. The testing of the Clarkson-Feeders for titration of the 5 reagents utilized in the flotation process has been completed.
The staged implementation of the final order of reagents, conditioning and residence time is being determined based on prior metallurgy work and existing equipment. The flotation chemistry utilizes a conditioner, gold promoter, sulphide promoter, activator, and frother. Determination is now underway to identify whether performance will be improved through staged addition of conditioner, gold and sulphides promoters followed by activator and frother or whether reagents will be combined in the single existing conditioning tank. Prior design utilized the ball mill and classifier as entry points for the initial 3 reagents, followed by activator and frother in the conditioning tank. The Company has added a centrifuge, for gravity primary design. This eliminates the possibility of treating the ore in the crushing circuit and reagents now must be added post-gravity recovery in the conditioning tank. A determination is being made to mix all reagents in a single step or adding a second conditioning tank for two phase reagent mixing either collectors and then activator/frother or two dosage mixing of all reagents. A final determination is expected shortly regarding the use of single or double conditioning tanks, with full-scale implementation of the flotation circuit to follow. All mechanical components are working and post-processing equipment including leaf-press and propane fired concentrate drying circuit are operational as well. Previous metallurgy work has determined a 97% recovery may be achieved with a combined gravity and flotation circuit with Fran Gold ore (see Press Release dated December 16, 2024 ).
Fran Gold Project
Data re-compilation of the 104 drill holes from Fran Gold continues. This now includes implementation of Leapfrog 3D modelling and resource estimate software, inclusive of pit-shell design for purpose of producing a resource estimate. The recent discovery of a bulk tonnage gold deposit at Fran ( see Press Release dated April 7, 2025 ) including 149m (488 ft.) of 0.9 grams per tonne has resulted in high priority focus on the re-evaluation of the Fran deposit.
Past exploration and development at Fran Gold, including over 18,000m (55,000ft.) of diamond drilling, has shown large intercepts of mixed vein and disseminated gold. The deposit area has been identified to be in excess of 1000m x 100m x 300m within a known strike length of 1700m. The Fran Gold Project is next to Centerra Gold's Mt. Milligan Project, with Reserves of 264Mt grading 0.3 gram per tonne gold and 0.2% copper and proximate to Artemis Gold's Blackwater Mine, with Proven and Probable Reserves of 334Mt grading 0.8 grams per tonne gold. Both Mt. Milligan and the Blackwater Mine are two of the largest new copper/gold and gold mines respectively, in North America.

Highlights
The grant will cover 50% of the direct drilling costs up to a maximum refund of $57,500. An initial two (2) diamond drillholes are planned to test the Ganymede IP geophysical anomaly previously identified but left undrilled by Meteoric Resources in 20221. Notably Ganymede has an IP signature equivalent to the Butchers Creek gold deposit. Drilling is planned to commence this 2025 field season with assay results scheduled approximately 6 weeks thereafter.
WIN Metals Managing Director and CEO, Mr Steve Norregaard, commented:
“We welcome the financial support of the Western Australian government via the 31st round of EIS grant funding.
This target represents a compelling opportunity to enhance the already significant Butchers Creek gold project. Without government support this target may well have remained untested.
Success with this would potentially be a step change for underpinning the economics of the project.
This support will fast track testing and we look forward to seeing what may be at Ganymede.”
Background
The Ganymede gold target is located to the south-east of the Butchers Creek open pit and Mt Bradley gold mines illustrated in Figure 1. Meteoric’s 2022 IP geophysical survey identified Ganymede to have a similar geophysical signature to the known Butchers Creek gold deposit. It is believed the Ganymede target is a potential fold repeat of the Butchers Creek gold deposit that has yet to be drill tested as is illustrated in Figure 2 below.
