Announcement PDF ASX Quarterly Report & Media Release ASX: KAL 29 January 2026 QUARTERLY ACTIVITIES REPORT for the quarter ended 31 December 2025 KalgoorlieGoldMiningLimited | ACN645666164 Suite 2, 1209 Hay St, West Perth WA 6005, Australia T: +61 (0)8 6002 2700 | E: info@kalgoldmining.com.au | www.kalgoldmining.com.au Kalgoorlie Gold Mining (ASX: KAL, KalGold or the Company) is pleased to report on its activities during the fourth quarter of 2025 (December quarter). Highlights: Pinjin Gold Project, Laverton Tectonic Zone (LTZ), 140 km ENE of Kalgoorlie • Extensive RC drill program defined widespread, continuous, primary orogenic gold mineralisation intersected in fresh rock at Lighthorse: o Gold mineralisation is directly associated with extensive shearing, alteration, sulphide mineralisation, and veining logged in intervals up to 35 m thick. o Primary orogenic gold mineralisation and anomalism extends north from previous RC drill coverage and now defines over 1,100 m of strike (600 m previously). o Confirms that the near-surface ~1,600 m long aircore anomalism is sourced from primary orogenic gold mineralisation below, and remains open to the north. o Corresponds with a Sub-Audio Magnetic (SAM) magnetometric conductivity (MMC) high that continues beyond the current extent of RC drilling. • Results defined a high-quality and extensive target consistent with a substantial gold mineralised system. o Infill and extensional RC drilling is expected to commence in early 2026, with first-pass aircore drill testing of gold targets east of Lighthorse within the Laverton Tectonic Zone and along strike from the Rebecca gold deposit. • Diamond drilling program (four holes, total 1,154.6 m) completed at the Kirgella Gift and Providence deposits. Lithological, alteration and structural logging completed. Holes cut and sampled, with assays awaited. Bulong Taurus Gold Project, 35 km east of Kalgoorlie • Commenced updated JORC Code (2012) Inferred Mineral Resource Estimate at La Mascotte to capitalise on the substantially increased gold price since previous modelling in early 2023 (AUD gold price has risen by around 250% compared with the early 2023 price used in modelling). Corporate • Balance sheet of $4.0 million cash and no debt as of 31 December 2025. • Strong news flow with results of the recent diamond drilling pending as well as upcoming drill programs. Page 2 QuarterlyOperationsReport,December2025 PINJIN GOLD PROJECT A successful RC drill program at Lighthorse during the quarter substantially extended the known footprint of gold mineralisation within fresh rock. The results define extensive gold mineralisation and anomalism, including thick gold mineralisation intercepts, over more than 1,100 m and open to the north. Importantly, gold mineralisation correlates with Sub-Audio Magnetic (SAM) conductivity anomalies, providing a geophysical technique with the potential to identify primary gold mineralisation in fresh rock throughout the area. The Company interprets these results to be consistent with large-scale orogenic gold mineralisation beneath cover at Lighthorse and is correspondingly accelerating exploration efforts at Pinjin in 2026. Figure 1 – Location map of the Lighthorse gold discovery at KalGold’s Pinjin Project around 140 km northeast of Kalgoorlie- Boulder. The project is situated approximately 25 km north of Ramelius Resources’ (ASX: RMS) Rebecca Gold Project. Also shown are KalGold’s JORC Code (2012) Inferred Mineral Resources, the outcropping La Mascotte deposit 35 km east of Kalgoorlie, and the Kirgella Gift and Providence deposits from only 3m depth at Pinjin. Projection: MGA 94 Zone 51. Lighthorse gold prospect Primary gold mineralisation at Lighthorse defined by RC drilling continues to follow gold anomaly footprints demarcated by first-pass aircore drilling. Primary gold mineralisation is now confirmed over 1,100 m strike, commensurate with the 1,600 m gold anomaly footprint defined by aircore drilling. Gold mineralisation and anomalism extends northwards from the initial discovery drill area and is open to the north. • Thick, sheared, veined, and altered mineralised zones are extensive and remain open to the north, corresponding closely with SAM magnetometric conductivity trends. Page 3 QuarterlyOperationsReport,December2025 • Gold mineralisation becomes increasingly discontinuous and diminishes between the Lighthorse Prospect and the T15 target. • The scale of the structures and the extent of the gold mineralised footprint indicate a high-quality exploration target with potential to host a significant gold deposit. The results of the program validate and support KalGold’s systematic exploration methodology but, more importantly, define a primary, orogenic gold mineralising system of substantial scale at Lighthorse. KalGold’s focus now is to define higher-grade and economically extractable parts of the Lighthorse gold system, which will be the target of upcoming drill programs. RC drill program results A total of 38 RC drill holes at Lighthorse (4,494 m, average depth of 118m) followed up on aircore anomalism defined in previous programs (ASX: KAL 15/07/25) and SAM geophysical anomalies (ASX: KAL 26/08/25). Drill holes substantially expanded on the Company’s first RC program at Lighthorse (ASX: KAL 15/04/25), expanding the area tested to the north and south and following an approximate, widely- spaced 100-150 m x 80 m pattern in the north, extending to 160-180 m x 80 m in the south. Table 1 – Selected drill hole intercepts from KalGold’s second RC drill program at Lighthorse that extended RC drill coverage along strike to the north. See Appendix 2 for a full listing. Enveloping zone gold anomalism is calculated at >0.1g/t Au cut-off with 2m maximum internal waste. Intercepts calculated at >0.5g/t gold cut-off (“Including” intercept >2.0g/t Au cut-off) with 2m maximum internal waste.

The thickest zones of RC gold anomalism and mineralisation correlate with highs in earlier aircore drilling results around 600 m northwest of the discovery site (Table 1). Gold mineralisation is inferred to dip steeply westward and is hosted within a mixed sequence of dacitic intermediates, basalt and ultramafic rocks, showing typical orogenic gold mineralisation characteristics including shearing, sulphide (pyrite) mineralisation, sericitic, carbonate, and silicic alteration, and extensive quartz(-carbonate- pyrite) veining. Page 4 QuarterlyOperationsReport,December2025 Page 5 QuarterlyOperationsReport,December2025 Figure 2 – RC drill collars (squares) over magnetometric conductivity (MMC) data defined by the recent SAM geophysical survey over the greater Lighthorse / Kirgella area. Broad zones of RC anomalism and mineralisation defined in this program (rounded label boxes) correspond with a linear north-south oriented MMC ridge in the north of the Lighthorse prospect. This contrasts with the south where anomalism is weaker and less continuous between Lighthorse and the T15 prospect further south. Also shown are earlier intercepts (squared label boxes) and aircore drill collars with contained gold (circular, same legend as RC collars). . A distinct mineralised structure appears to parallel the MMC conductivity defined by the recent SAM geophysical survey. The mineralised structure (white dashed arrows) is defined in drilling by extensive shearing, alteration, veining and sulphide mineralisation. It is thick and laterally extensive and is open to the north. First-pass RC drilling in this area was widely spaced (approx. 100-120m x80m) and not comprehensive. Infill and extensional drilling to greater depths is required to fully define the structure and distribution of gold mineralisation. RC collars represented as squares, with faded circles defining collars of earlier aircore collars. Notes on the underlying SAM imagery: • Magnetometric conductivity tilt derivative, grid combined • Conductivity ranges from -1.55pT/A (blue, low) to +1.56pT/A (pink, high). • See ASX: KAL 26/8/25 for full details. Projection: MGA 94 Zone 51. Broad footprint and thick intercepts define targets for large deposits at Lighthorse Extensive, continuous distributions of gold mineralisation and anomalism in fresh rock correlates directly with broad thicknesses of altered, veined and sheared rocks which are characteristic features of orogenic gold deposits. In cross section (Figure 3), thick zones of gold mineralisation and anomalism defined in this first RC drilling at this location can be correlated across adjacent, widely-spaced drill holes, suggesting that each hole has sampled only a portion of the full thickness of the structure. Therefore, the true thickness may be cumulative and in excess of 100 m (Figure 3). Further drilling is required to confirm the scale of these structures. The widespread distribution of alteration, veining, and shearing mean that these rocks are key features of large-scale hydrothermal plumbing systems. Such systems can form significant gold deposits along their length given suitable conditions. Figure 2 – Cross section looking northward through the new RC drilling at the northern end of Lighthorse. Orientations are not confirmed but consistent with observations from previous RC drilling to the south. Similarly depth of near-surface gold depletion is not yet defined but may extend below current drill depths and will be defined by further drilling. Broad shearing, alteration, veining, and mineralisation are present in thick zones, but the observation of thick zones in adjacent drill holes suggests that true thicknesses could be cumulative. Graphically, narrower intercept cylinders are based on a 0.1 g/t Au cutoff, whereas wider intercepts are based off a 0.5 g/t Au cutoff, coloured according to gold content. MGA 94 Zone 51. 6,660,900 mN section Page 6 QuarterlyOperationsReport,December2025 Gold correlation with SAM geophysical anomalies at Lighthorse Gold anomalism and mineralisation at Lighthorse correlates strongly with MMC features defined in the recent Sub-Audio Magnetic (SAM) geophysical survey (ASX: KAL 26/8/25). Zones of strong gold mineralisation intersected through the northern and central Lighthorse areas are characterised by a conductivity high (ridge) and contrasting magnetic low. Where the conductivity diminishes between these areas, so does the intensity of anomalism and gold mineralisation detected in RC drilling (Figure 2). Similarly, the discontinuous and weaker gold anomalism to the south of Lighthorse is reflected in the similarly discontinuous MMC data. The extension of the conductivity ridge north of the current limit of RC drilling is very promising for the potential identification of additional gold mineralisation to the north. The Company is currently looking to engage geophysical consultants to complete 3D inversion modelling of the SAM geophysical data to potentially unlock further value from this dataset. Further afield, the geophysical method shows good potential as a geophysical proxy for identifying gold mineralisation beneath cover throughout the Pinjin area. Results from other prospects A total of 10 RC holes for 1,404 m were completed across Wessex and Providence South: • Wessex: 7 holes for 1,004 m (average depth = 143 m) • Providence South: 3 holes for 400 m (average depth = 133 m) Drilling was designed to follow up near-surface gold anomalism detected in aircore drilling during 2024. At Providence South, holes KGRC25025 (2 m @ 2.40 g/t Au from 95 m) and KGRC25026 (4 m at 0.89 g/t Au from 114 m) returned narrow mineralised drill intercepts within, or proximal to the offset ultramafic unit that hosts the neighbouring Kirgella Gift and Providence deposits. The Providence South area will continue to be assessed as part of the greater Lighthorse and Kirgella Gift gold system. At Wessex, the thickest and strongest previous aircore results in the north (ASX: KAL 09/10/24) disappointingly were not underlain by any significant primary gold in deeper drilling. In the south, RC drilling returned some instances of gold mineralisation, such as 8 m at 1.00 g/t Au from 46 m in hole KGRC25022, including 4 m @ 1.80 g/t Au from 46 m. The Company will continue to assess the Wessex area and monitor activity by Hawthorn Resources (ASX: HAW) at Anglo Saxon across the tenement boundary, but it is clear that the Lighthorse and Kirgella area, plus new targets to the east must take priority. Diamond drilling at Kirgella Gift and Providence Four diamond drill holes were completed during the quarter at Kirgella Gift and Providence gold deposits, for a total of 1154.6 m. Processing of drill core from the program is complete, with samples submitted to the laboratory for assay. Results are pending. Data generated from logging, including structural data, is being analysed and will be integral to interpretation of assay results. During the quarter, the Company submitted its interim post-program report to the Department of Mines, Petroleum and Energy and received an initial 80% refund under the Exploration Initiative Scheme (EIS). The remaining 20% refund will become available upon submission of a final report and submitting the remaining half of the drill core to the Joe Lord Core Library in West Kalgoorlie. Page 7 QuarterlyOperationsReport,December2025 Accelerated exploration programs at Pinjin Positive results from this quarter’s drilling have prompted the Company to accelerate its efforts at Pinjin. Upcoming 2026 RC drill programs are being designed to achieve the following: • Accurate definition of the distribution, geometry and continuity of primary gold mineralisation across Lighthorse through tightly- spaced and deeper penetrating drill holes; and • Extension of widely-spaced drilling to the north (along strike) and south (into the T15 target) to define the full extent of primary orogenic gold mineralisation. RC drilling will be augmented by new aircore drill programs in 2026, including: • First-pass aircore drilling across multiple targets within a broad area east of Kirgella Gift and Lighthorse. These targets are located on a flexure in the Laverton Tectonic Zone along strike from and within the same rock package as Ramelius Resources’ (ASX: RMS) Rebecca gold deposit. • Other target testing throughout the greater Pinjin Gold Project. Additional exploration licence applications are progressing, and the Company continues to assess opportunities throughout the Pinjin area and along strike in the Laverton Tectonic Zone. BULONG TAURUS GOLD PROJECT Continuous assessment of the Company’s JORC Code (2012) Inferred Mineral Resources has identified that recent increases in the gold price offer an opportunity to remodel, refine, and enhance the Company’s La Mascotte Inferred JORC Code (2012) Mineral Resource Estimate (MRE). Since the definition of the first resource estimate, the AUD gold price has risen by around 250% from the early 2023 price, so factors that could be changed in this re-estimate include: Figure 3 – Target areas for forthcoming exploration programs as presented in previous reports. Highlighted target areas will be the focus of future drill programs Background: state aeromagnetic datasets. Projection: MGA 94 Zone 51. Page 8 QuarterlyOperationsReport,December2025 • Lowering the gold cut-off grade, in line with anecdotal information suggesting supply to commercial mills as low as 0.5 g/t Au; • Refining model detail in line with uncertainties inherent in the datasets; and • Adjusting mining cost estimates commensurate with the increased gold price and to reflect current conditions. Work commenced on the updated MRE at the end of the quarter. The Company will report the results once completed. Separately, productive discussions with Traditional Owners continue to progress. OTHER PROJECTS During the quarter, two non-core projects on which the Company held gold rights and with no geographic synergies to other KalGold projects, were sold to other parties. • The Perrinvale gold project was sold to Ballard Mining (ASX: BM1) to complement its Mt Ida gold project. The project comprised a single tenement with several near-surface gold anomalies but no historic mining. The consideration for the sale was 54,434 BM1 shares (approximately A$50k at BM1 closing price as at 27 Jan 2026) which are subject to a 6-month escrow period. • The Black Range gold project was sold to Ora Banda Mining (ASX: OBM) to complement their local operations. The package comprised four small exploration tenements with gold anomalism but no historic mining in an area of extensive gold exploration. KalGold’s portion of the consideration for the sale was $20,000. Discussions are underway on other outlying projects. Field programs at KalGold’s other non-core projects aimed to further advance these early-stage projects through geophysical data interpretation, mapping and surface sampling activities. No material results were reported. COMPANY TOTAL GOLD RESOURCE KalGold’s total JORC Code (2012) Inferred Mineral Resource base remains at 214,300 ounces of gold (Table 2). KalGold’s low-cost gold resources are either outcropping or located within metres of surface. At both Pinjin (Kirgella Gift, Providence) and Bulong Taurus (La Mascotte) (Figure 1), overall gold grades exceed 1.0 g/t Au, with both projects containing zones of higher-grade, near-surface gold mineralisation that may be amenable to open pit mining. Table 2 – KalGold Total Mineral Resource statement. Bulong Taurus (La Mascotte) reported at a 0.6 g/t gold cut- off (7 March 2023), and the Pinjin (Kirgella Gift and Providence) reported at a 0.5 g/t gold cut off (25 July 2024). Totals may not sum due to rounding. The Company confirms that the material assumptions and technical parameters underpinning the JORC Code (2012) Inferred Mineral Resources Estimates continue to apply and have not materially changed.
