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. _____________________________________________________________________________________________________________________________ Principal and Registered Office Suite 9 / 11 Ventnor Avenue West Perth, Western Australia 6005 | Postal PO Box 437 West Perth, Western Australia 6872 Contact admin@castleminerals.com | www.castleminerals.com | Telephone +61 8 93227018 Board: Executive Chairman, Stephen Stone | Non-Executive Directors, James Guy.

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 underexplored 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.” Page 2 of 15 Castle Minerals Limited: Kpali Gold Prospect RC Drilling Results – 13 February 2025 Fig 2: North-south long-section through mineralised hangingwall and footwall lodes at Kpali highlighting zones of shallow plunging, high-grade gold mineralisation. 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). 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 worldclass gold mining operations in Ghana and West Africa generally. Orebodies with these characteristics can often extend to considerable depth.

This latest drilling programme focused specifically on extending zones of high-grade, lode-based mineralisation that appears to plunge to the north. Better intercepts (>1g/t Au, max 2m internal dilution) from the eight holes completed included: • • • • • • • 12m at 8.29g/t Au from 25m (24KPRC010) incl. • 6m at 11.60g/t Au from 31m and • a peak 1m intercept value of 20.43g/t Au at 36m and • 4m at 4.16g/t Au from 95m. 7m at 2.23g/t Au from 35m (24KPRC011) incl. • 4m at 3.23g/t Au from 35m and • 11m at 2.24g/t Au from 50m incl. • 1m at 8.29g/t Au from 57m. 5m at 3.66 g/t Au from 78m (24KPRC012) incl. • 2m at 7.09g/t Au 79m. 13m at 1.58g/t Au from 73m (24KPRC014) incl. • 1m at 5.62g/t Au from 79m. 1m at 8.35g/t Au from 5m (24KPRC015) and • 9m at 4.81g/t Au from 107m incl. • 2m at 8.75g/t Au from 109m. 1m at 6.64g/t Au from 70m (24KPRC016). 7m at 1.67g/t Au from 39m (24KPRC017) and • 3m at 3.08g/t Au from 78m. Page 4 of 15 Castle Minerals Limited: Kpali Gold Prospect RC Drilling Results – 13 February 2025 These latest results enhance the confidence obtained from the two prior programmes which included 4m at 3.66g/t Au from 26m, 3m at 5.20g/t Au from 125m, 28m at 2.26g/t Au from 81m including 5m at 8.41g/t, 10m at 2.01g/t Au, 5m at 4.53g/t Au, 11m at 1.86 g/t Au from 143m and 3m at 5.20g/t Au from 125m (refer Fig 1 for historical and recent drill intercepts at the Kpali Gold Prospect and also to relevant ASX releases listed in Table: Previously Reported Information Relating to this Release). Northern Ghana and the Kpali Gold Project A compelling driver for exploring Northern Ghana’s Kpali Gold Project is its advantageous location at the convergence of two major greenstone belts (Bole-Bolgatanga and Wa-Lawra/Boromo) and three regional-scale structures. These are all associated with gold deposits. This supports the thesis that the region provides a large and prospective “search base” for the discovery of a major new West African mining camp. Northern Ghana has more recently seen two of West Africa’s better discoveries and success stories. The 5.1Moz Namdini gold deposit, discovered by Cardinal Resources Limited prior to its takeover by Shandong Gold Limited in 2020, has just been commissioned and lies on the same Bole-Bolgatanga Birimian greenstone belt as Castle’s Kandia discovery. The Azumah Resources Limited owned 2.8Moz Black Volta Gold Project (“BVGP”) is earmarked for development in 2025. A majority of this gold was discovered by Castle’s Executive Chairman, Stephen Stone, under his former stewardship of Azumah. Castle’s Kandia mineralised trend is immediately along strike of the BVGP’s high-grade Julie deposit. Fig 4: Kpali Gold Project showing key prospects and VTEM derived targets on reprocessed VTEM geophysics. Page 5 of 15 Castle Minerals Limited: Kpali Gold Prospect RC Drilling Results – 13 February 2025 The discovery of mineralisation at the Kpali Gold Project’s Kpali, Bundi, Kpali East, Wa South East and Wa South West prospects are essentially “blind” discoveries in that the bedrock hosting mineralisation is largely obscured by extensive but generally shallow soils and alluvium. This explains the lack of artisanal mining activity which often leads explorers into a new area. Castle’s structured and systematic approach to exploration in this environment is proving highly effective across its extensive tenure. Fig 5: Ghana’s northern region showing key deposits, the convergence on Castle’s Kpali Gold Project of the Wa-Lawra and Bole-Bolgatanga Birimian greenstone belts plus three major structures associated with major Birimian hosted gold deposits, and Castle’s other Wa Gold Project prospects. What’s next at Kpali? The enormous encouragement from this latest drilling campaign at the Kpali Gold Prospect, and the presence of several other high conviction targets within the Kpali Gold Project, reinforces Castle’s belief that one or more material discoveries could be made. Once the information provided by this latest round of drilling has been fully processed, integrated with existing data and fully interpreted, a follow-up drilling campaign will be designed and implemented. Kandia and other Wa Gold Project prospects The Company’s Wa Gold Project comprises extensive tenure prospective for gold within Ghana’s Upper West Region. As well as the Kpali Gold Project and the Kandia Project, there are many other targets worthy of investigation on a prioritised basis. Page 6 of 15 Castle Minerals Limited: Kpali Gold Prospect RC Drilling Results – 13 February 2025 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 (refer ASX release 28 Jan 2025 ‘Excellent Gold Intercepts From Drilling at Kandia Prospect’). Exploration and mining in West Africa and Ghana West Africa is one of the world’s premier regions to be exploring for gold, delivering an enviable fifteen discoveries of over two million ounces each since 2012. Ghana’s northern region is now considered one of the best areas to find more of these. Ghana is rated one of Africa’s most preferred jurisdictions for exploration and mining. It is Africa’s number one gold producer at over 5Moz in 2024 and is the sixth largest gold producer in the world. It is host to several massive deposits operated by Tier-One companies such as Newmont, AngloGold-Ashanti and Zijin, which recently paid Newmont US$1 billion for its Akyem mine. Newmont operates the 20Moz - 570,000oz per year Ahafo deposit and is about to invest ~US1 billion developing the 300,000oz per year Ahafo North mine. AngloGold’s 127 year old, 1,500m deep Obuasi mine has a mineral resource of 34Moz and once a US$500m redevelopment programme is completed is expected to produce 400,000oz per year at a grade of over 8g/t Au. Shandong Gold acquired the 300,000oz per year Cardinal Resources Limited and its Namdini mine for US$450 million. Other major operators are Perseus Mining Limited (Edikan mine) and Asante Gold (Bibiani and Chirano mines). Ghana is a very stable, safe and mining friendly English speaking jurisdiction. It has a democratically elected Westminster-system of government and operates under a British-based justice system. The recent December 2024 Presidential election saw a peaceful transition to a new pro-development government. Ghana has a modern and expanding infrastructure, reliable power, international ports and airport and is the main hub for most international governments, banks, NGOs and major companies with interests in the West African region. There is a plentiful and highly skilled top-down work force and practically all mining services and supplies are available in-country. The Company is not aware of any material changes in the status of the historical information reported in this release.

These examples should not be taken as limiting the broad meaning of sampling. Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. Aspects of the determination of mineralisation that are Material to the Public Report. In cases where ‘industry standard’ work has been done this would be simple (e.g., ‘reverse circulation drilling was used to obtain 1 m samples from which 3kg was pulverised to produce a 30g charge for fire assay’). In other cases, more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (e.g., submarine nodules) may warrant disclosure of detailed information. RC drill cuttings were collected at regular one metre intervals during drilling operations. • Drill type (e.g., core, reverse circulation, openhole hammer, rotary air blast, auger, Bangka, sonic, etc.) and details (eg core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc.). The drilling programme was completed using a reverse circulation drill with a 110mm face sampling hammer. • Method of recording and assessing core and chip sample recoveries and results assessed. Measures taken to maximise sample recovery and ensure representative nature of the samples. Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. Sample volume returns were monitored visually during drill operations by the rig geologist. There were no wet samples collected during the drill program. Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. Geological logging of the drill chips was completed by a qualified geologist using a company standard logging code. The logging included descriptions for color, lithology, mineralogy, structure, grain size, alteration, alteration intensity, weathering. • Sampling techniques • • Drilling techniques • Drill sample recovery Certified Person Commentary • • Logging • Page 10 of 15 The sampling methods employed are standard industry practice, and were supervised by qualified and experienced geological personnel employed by Castle. RC samples were processed and using standard industry practices of sorting, drying pulverizing followed by fire assaying by Intertek Laboratories (Ghana) In the RC drilling, the cyclone and sample hose were regularly purged and cleaned during drill operations to minimise contamination. There does not appear to be a relationship between sample recovery and grade. RC logging is semi qualitative, given the nature of the rock chip fragments. Castle Minerals Limited: Kpali Gold Prospect RC Drilling Results – 13 February 2025 Criteria JORC Code explanation • The total length and percentage of the relevant intersections logged. Chip trays were collected for each RC hole and photographed. • If core, whether cut or sawn and whether quarter, half or all core taken. If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. For all sample types, the nature, quality and appropriateness of the sample preparation technique. Quality control procedures adopted for all subsampling stages to maximise representivity of samples. Measures taken to ensure that the sampling is representative of the insitu material collected, including for instance results for field duplicate/second-half sampling. Whether sample sizes are appropriate to the grain size of the material being sampled. Bulk samples were collected at metre intervals via a cyclone. Intervals displaying strong alteration, sulphide mineralisation or quartz veining where selected for immediate individual sampling with the remainder of the hole sampled at the conclusion of drilling. The original one metre bulk sample bags were passed through a 3tier riffle splitter and a 2–3kg subsample was collected in a numbered calico bag. The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established. Samples were sent to Intertek Laboratories (Ghana) at Tarkwa Ghana. The entire sample was dried and pulverised to a nominal 85% passing 75 micron. A 50g subsample was collected and analysed for gold by fire assay with a AAS finish (FA50L/AA). The verification of significant intersections by either independent or alternative company personnel. The use of twinned holes. Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. Discuss any adjustment to assay data. No independent or alternative company has been engaged to verify the results. • • Subsampling techniques and sample preparation • • • • • Quality of assay data and laboratory tests • • • • Verification of sampling and assaying Certified Person Commentary • For quality control purposes field duplicates were undertaken at a rate of one per every 20 samples. The sample size is considered appropriate for the grain size of the material being sampled. The Company inserted certified reference standards at a rate of 1 sample per 40 samples. Blank samples were inserted at a rate of 1 sample per 20 samples and field duplicates were inserted at a rate of 1 sample per 20 samples. In addition, the laboratory undertook its own internal quality control checks. The QA/QC protocols did not identify any sampling or laboratory bias in the results. Data on collar position, sampling intervals and drill hole lithology were recorded in the field on a standard Microsoft Office excel worksheet in. The field data is stored in the company’s Cloud server. The company’s database manager validates the data and merges it with assay data into a relational database maintained by the company. The Company maintains in Perth all original digital field data files and assay reports. Assay data is reported by the laboratory in ppb and the Company converted the assay results to ppm. • Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. Drill collars were positioned by handheld GPS receiver. A licensed surveyor has been contracted to record the location of the drill collars using a DGPS receiver with an accuracy of 10 mm. • Specification of the grid system used. • Quality and adequacy of topographic control. Data locations are supplied in WGS84 datum, UTM Zone 30N projection. The DGPS survey of the drill collars is sufficient for the current purposes. There has not been a LIDAR survey over the area. Location of data points Location of data points Page 11 of 15 Downhole surveying was completed using a digital Reflex instrument operated by the drill contractor. Hole azimuth data was adjusted for magnetic declination. Castle Minerals Limited: Kpali Gold Prospect RC Drilling Results – 13 February 2025 Criteria Data spacing and distribution JORC Code explanation • Data spacing for reporting of Exploration Results. Whether the data spacing, and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. Whether sample compositing has been applied. The RC drill programme was designed to infill the existing Kpali prospect RC drilling. Whether the orientation of sampling achieves unbiased sampling of structures and the extent to which this is known, considering the deposit type. If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. There is no surface outcrop to accurately determine the orientation of the major geological units or gold mineralisation. RC holes were orientated perpendicular to the strike of the inferred RAB and auger geochemical anomalies. Interpretation of the geology and gold assay data suggests the drilling orientation is approximately perpendicular to the strike of the mineralisation. • The measures taken to ensure sample security. Individual 1 metre samples for assay were collected into bulka bags by Castle site personnel.
