- 5m at 3.49g/t Au from 82m within 11m at 2.26g/t Au from 79m (24KARC004).
- 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.

OPINION — Goldenomics 101: Follow the Money
By Darren Brady Nelson
As an economist, I, perhaps somewhat sadly, have many economist friends. One of them recently alerted me to a post on X that was even a shock to me in the toxic 2020s. That being: “Almost all political donations by Fed employees go to one party. The Fed is already politicized.”
The post had a link to the data supporting this assertion, which was published at OpenSecrets. They are a “501(c)3” devoted to: “tracking money in US politics and its effect on elections and public policy.” Their theme is appropriately “Follow the Money,” as it is for this story.
Political money contributions, since 2016, from those at the Fed, range between 92 to 93 percent for Democrats and 8 to 9 percent for Republicans. As Public Choice economics teaches, it is crucial to “Follow the Money” in politics. Austrian and Chicago schools of economics teach the same for gold.
Gold pricing 101
Gold pricing is often characterized as being driven by “fear and uncertainty,” at least in the short run, including geopolitical fears like war and economic uncertainties such as recession. It is also typically recognized to be an “inflation hedge,” in the long run anyway.
Gold is an asset with a price determined in a 24/7/365 global auction, most often quoted per troy ounce, in the world’s reserve currency of US dollars. New supply plays an unusually small role compared to almost all other commodities, goods or services. Thus, highest bid wins.
Perhaps none of these things about gold, and its price, are new nor surprising. But what might be, despite the end of the gold standard in 1971 and legalization of gold investment in 1974, is that gold is still a shadow currency to fiat ones, especially US dollar, in the "always run."
The annual gold price from 1960 to 2024 is displayed below, as sourced from the World Bank. Rises include: late 1970s; late 2000s; and mid 2020s. Slides include: early 1980s; late 1990s; and early 2010s. Overall growth was: Sum 555 percent; Ave 8.7 percent; Max 98 percent; Min -24 percent; and CAGR 6.8 percent.
Money supply 101
Gold is the inflation hedge, precisely because it is shadow currency. Money supply is the inflation source, precisely because it is fiat currency. As Chicago economist Milton Friedman wrote in Money Mischief (1994): “In the modern world, inflation is a printing-press phenomenon.”
There are multiple money supply measures, such as M0, M1, M2 and M3. M1 includes paper and coin currency held by the general public as well as liquid bank deposits (e.g. checking accounts). M3 includes M1, plus less liquid bank deposits (e.g. savings accounts) as well as “repos.”
Austrian economist Robert Murphy details in Understanding Money Mechanics (2021) just how the Fed’s printing, Treasury bonds and bank loans create US money supply, through open market operations. Since 2008 and 2020, the Fed has expanded to buying and selling just about anything.
Speaking on behalf of the Fed, and all major central banks, the Bank of England wrote in Money Creation in the Modern Economy (2014): “(B)ank lending creates deposits. At that moment, new money is created. (This is) ‘fountain pen money,’ created at the stroke of bankers’ pens(.)”
Annual M1 and M3 money supply from 1960 to 2024 are displayed below, as sourced from the OECD. M3 starts to take off from the mid 1990s. Both blast off in the early 2020s, M1 in part due to redefinition. Combined growth was: Sum 533 percent; Ave 8.3 percent; Max 126 percent; Min -6.4 percent; and CAGR 7.4 percent.
Gold inflation 101
Christian economist Gary North points out in Honest Money (2011) that businesses have three choices in the face of money inflation: A) profit deflation; B) price inflation; C) quality shrinkflation. Investors have a fourth: D) gold inflation. A, B, and C are all bad options. D is good.
The chart below shows cumulative annual growth of gold versus M1 and M3. Gold performs and protects against both M1 and M3 from 1974 to 2019, even in 2001, but not against M1 from 2020 to 2024. In 2019, gold had a 150 percent lead on M1 and 92 percent on M3. By 2022, it shrunk to -110 percent and 80 percent.
Cumulative yearly growth (percent).
Sources: OECD and World Bank.
A 2020 regression study found: “When the Federal Reserve increases money supply by 1%, gold prices increase by 0.94%.” A 2023 academic paper: “Confirms a long-term relationship between gold price and US M2.” Note that M1’s 2021 redefinition has now made it nearly identical to M1.
Period yearly change (percent).
Sources: OECD and World Bank.
However, the authors of Austrian School for Investors (2015) wrote: “Gold does not correlate with the rate of inflation as such, but with the rate of change of the inflation rate. In order to buttress this hypothesis, we calculated the regression depicted in (the chart below).”
Source: Austrian School for Investors: Austrian Investing between Inflation and Deflation.
In conclusion, as per my Wokenomics 101 (2023) ghost blog, money inflation by: “increasing demand puts upward pressure on price and quantity and downward pressure on quality.” That puts upward pressure on: nominal CPI and GDP statistics; as well as real gold investment and price.
Inflation doesn’t harm all. It helps some. They are the “Bootleggers and Baptists,” as Public Choice economist Bruce Yandle dubbed them in 1983. Bootleggers are crony capitalists, politicians and bureaucrats whose inflated revenue outpaces costs. Baptists are the “useful idiots.”
Thus, “Follow the Money” back to the “inflationistas” of: Big Business; Big Government; and Big Banks. All gain supernormal profits from easy money: one, making more money; two, collecting more money; and three, creating more money. Also, “Follow the Money” when it comes to gold.
And, sadly, there is one policy that is always bipartisan; print more money. But, gladly, gold will always win.

High-Grade Gold Discovery in First 8 Mile Drill Hole
- First RC hole at 8 Mile discovers high-grade gold and ends in mineralisation
- 8 Mile gold mineralisation extends 75m north of tenement boundary
The 8 Mile target is located within the Gidji JV Project (“Gidji” or “the Project”), approximately 15 kilometres north of Kalgoorlie and surrounded by multiple gold mining and processing operations, including Northern Star Resources Limited’s (“NST”) Kalgoorlie gold operations (Figure 1).
The 8 Mile Target is located immediately adjacent to NST’s “8-Mile Dam” gold deposit which, according to the most recent publicly available data, contains an estimated 7Mt @ 1.4g/t Au for 313,977 ounces1.
A limited number of fast-tracked results from the first RC hole, GJRC029, show a wide zone of gold mineralisation with a similar tenor to 8 Mile Dam (18m @ 0.94g/t Au from 480m including 1m @ 6.04g/t Au), approximately 75m north of the tenement boundary, and ended in mineralisation (3m @ 0.52g/t Au).
The Company is awaiting assay results from the remainder of the hole which are expected in 2-3 weeks.
Miramar’s Executive Chairman, Mr Allan Kelly, said the Company was excited to see gold mineralisation continuing onto Miramar’s ground for a significant distance.
“This is the first time we have discovered significant gold mineralisation on our side of the fence, even though the drill hole didn’t end up exactly where we planned it to. The flip side of this is that we have extended the strike of gold mineralisation for over 100m on to our tenements,” he said.
“We’ve also demonstrated a relationship between the IP anomalism and gold mineralisation, which makes the other IP anomalies we have outlined at Gidji even more prospective,” he said.
Figure 1. The Gidji JV Project and 8-Mile Dam in relation to Kalgoorlie and surrounding deposits.
GJRC029 aimed to test an Induced Polarisation (IP) anomaly on the tenement boundary interpreted to represent the sulphide-rich gold mineralisation seen at the neighbouring 8 Mile Dam Deposit.
GJRC029 was collared approximately 10m north of the tenement boundary and mirrored MPGD008, a diamond hole drilled down-dip approximately 40m south of the tenement boundary by KCGM in 2013 and which intersected significant gold mineralisation related to the 8 Mile mafic unit.
Unfortunately, GJRC029 deviated significantly from the planned azimuth and, as a result, by the time the hole was terminated at the target depth of 504m, the drill trace ended up approximately 75m north of the tenement boundary (Figure 2). Despite this, the hole intersected a thick section of the steep westerly- dipping and highly altered 8 Mile mafic unit with widespread sulphide mineralisation, including disseminated magnetite and coarse-grained arsenopyrite, pyrrhotite and chalcopyrite, similar to the 8 Mile Dam Deposit (Figure 3).
Based on visual logging of RC drill chips, handheld portable XRF results and magnetic susceptibility measurements, samples from the bottom 56m of the hole were sent for priority analysis by fire assay at Bureau Veritas in Kalgoorlie.
The results from these initial samples confirm the relationship between the gold mineralisation and sulphides, and a relationship between the best gold mineralisation and coincident magnetic anomalism and elevated Arsenic as measured by handheld portable XRF. The first results also confirm that the IP anomaly is associated with potentially significant gold mineralisation, whilst the significant deviation of GJRC029 away from the planned target increases the potential strike length of gold mineralisation on Miramar’s ground.
Significant results are listed in Table 1, with assay results from the remainder of the hole expected in coming weeks.
The initial RC drilling programme, which also tested two other IP targets, is nearing completion and results will be reported once received and compiled.
Once all assays are received, the Company will plan further RC and/or diamond drill holes including to test the dip and strike extent of the mineralisation intersected in GJRC029.
The Company advises that the WA Department of Mines, Petroleum and Exploration (DMPE) has extended the main Gidji JV tenement, E26/214, for a further five years, and will now expire in March 2030.
