ASX Announcement ASX: LAC | lacgold.com | investors@lacgold.com p2 Lac Gold Managing Director Andrew Stocks said: “These are very strong results, which highlight the potential for substantial growth in our existing 1.66Moz Rouyn Mineral Resource. “They reveal further broad intervals of mineralisation, including some very high grades. “But just as importantly, the drilling is showing that gold mineralisation extends beyond the mineralising unit into the surrounding rocks. This could have significant implications for future resource growth and mining scenarios we consider at Rouyn. “Our increasing understanding of the geological and structural controls is also helping us identify new resource targets and refine our drilling priorities. “Our updated Rouyn Mineral Resource Estimate is progressing well towards completion in Q1 2027, incorporating results from this announcement. Meanwhile, we're continuing to drill at Astoria, building on what we learn with each stage of the program.” Rouyn-Noranda, Québec, Canada – Lac Gold Limited (ASX: LAC) is pleased to report more strong assays from nine diamond drillholes (AS-26-819 to AS-26-827) completed at the Astoria deposit within its 100%-owned Rouyn Gold Project in Québec. The standout result is AS-26-827, which returned 10.0m at 8.28g/t Au from 195.0m, including 4.0m at 15.80g/t Au from 200.0m, within a broader mineralised interval of 50.0m at 2.03g/t Au from 160.5m. Other significant results include AS-26-826, which returned 9.0m at 5.20g/t Au, including 1.5m at 27.00g/t Au, and AS-26-824, which intersected 31.55m at 1.39g/t Au, including 3.25m at 5.34g/t Au and 1.35m at 5.78g/t Au. Significant higher-grade intervals were also returned from AS-26-819 and AS-26- 825. Together with earlier results from the 2026 drilling program, these intersections continue to demonstrate broad gold mineralisation containing higher-grade zones at Astoria. The drilling is also improving the Company's understanding of the distribution and geological controls of mineralisation, including its occurrence within sedimentary rocks beyond the principal ultramafic host rocks. Understanding the Rouyn Gold System The Rouyn Gold Project, including the Astoria area, forms part of a structurally controlled orogenic gold system associated with the Cadillac-Larder Lake Break in Québec's Abitibi gold region. Mineralisation occurs within and around the altered ultramafic rocks of the Piché Group, together with adjacent volcanic and sedimentary formations of the Blake River and Timiskaming groups. Historically, much of the geological interpretation and Mineral Resource modelling at Rouyn has focused on mineralisation associated with the altered Piché ultramafic corridor. However, the Company's 2026 drilling at Astoria is providing increasing evidence that significant gold mineralisation also occurs within the surrounding rock formations. This is contributing to a broader understanding of the gold system, including the potential importance of geological structures and lithological contacts in controlling the distribution of mineralisation. ASX Announcement ASX: LAC | lacgold.com | investors@lacgold.com p3 Figure 1 - Project areas and geology of the Rouyn Gold Project A Broader Mineralised System The latest drilling is improving the Company's understanding of the geometry, distribution and potential continuity of mineralisation at Astoria. Hole AS-26-827 is particularly significant. Its 50.0m mineralised intersection, including 10.0m at 8.28g/t Au, demonstrates substantial higher-grade mineralisation within a broader mineralised interval. The result is contributing to a revised geological interpretation of this part of Astoria, where mineralisation may be more extensive than previously modelled. The drilling is also highlighting the importance of gold mineralisation beyond the principal ultramafic host rocks. AS-26-825 intersected 10.0m at 1.86g/t Au, including 0.54m at 26.70g/t Au, entirely within sedimentary wackes. This result demonstrates significant gold mineralisation within the footwall sediments and reinforces the importance of considering these rocks in future exploration and geological modelling. AS-26-824 intersected 31.55m at 1.39g/t Au, including 3.25m at 5.34g/t Au and 1.35m at 5.78g/t Au, within the ultramafic volcanic sequence, further demonstrating the occurrence of higher-grade mineralisation within broader mineralised intervals. Together, these results are contributing to a more comprehensive geological interpretation of the Astoria gold system and helping identify additional opportunities for future exploration. ASX Announcement ASX: LAC | lacgold.com | investors@lacgold.com p4 Improving Understanding of Structural Controls The Company's geological team is developing a clearer understanding of the structural settings associated with higher-grade gold mineralisation at Astoria. Of particular interest is the contact between the Piché ultramafic rocks and the adjacent Blake River volcanic sequence. The contrasting mechanical properties of these rock types are interpreted to have influenced deformation, creating favourable conditions for the development of quartz-carbonate vein networks and gold mineralisation. Higher-grade gold mineralisation is commonly associated with quartz-carbonate veining, localised deformation and characteristic alteration assemblages, with intrusive dykes also observed in some mineralised areas. These observations are helping the Company identify and prioritise geological settings that may be favourable for higher-grade gold mineralisation, providing a more focused approach to future exploration drilling. While further drilling is required to establish the continuity and extent of mineralisation in these settings, the improving geological interpretation is helping guide the Company's exploration strategy at Astoria. Figure 2 - Astoria long section showing the latest drilling, significant intersections and existing Mineral Resource envelopes ASX Announcement ASX: LAC | lacgold.com | investors@lacgold.com p5 Mineral Resource Update Progressing Towards Q1 2027 Lac Gold's updated Mineral Resource Estimate (MRE) for the Rouyn Gold Project is progressing well, with Measured Group undertaking the resource estimation work and completion targeted for Q1 2027. Results from this announcement will be incorporated in the update planned for Q1 2027. The update incorporates historical drilling information, additional validated drilling data from the 2026 program and the Company's revised geological interpretation, with particular emphasis on improving the definition and understanding of mineralisation at Astoria. The update will assess the impact of additional drilling information and refined geological interpretations on mineralised tonnes, grade, contained gold and Resource classification. The outcome will be determined through the estimation process. The Rouyn Gold Project currently hosts a previously reported Mineral Resource Estimate of 1.666 million ounces of gold at 3.28g/t Au, comprising Indicated and Inferred Resources (refer page 12). The existing MRE is dated April 2025 and was subsequently reported to the ASX in October 2025.

Section 1 Sampling Techniques and Data Criteria JORC Code explanation Commentary Sampling techniques • Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as downhole gamma sondes, or handheld XRF instruments, etc.). These samples 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 relatively simple (e.g. ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g 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. • Samples have been collected by diamond drilling techniques (see below). • Drillholes are orientated perpendicular to the interpreted strike of the mineralised trend except where limited access necessitates otherwise. • Diamond core sampled in intervals of ~1 m where possible, otherwise intervals less than 1 m selected based on geological boundaries. • The core was logged, cut, and sampled by qualified personnel at Explo-Logik core shack in Val D’Or and samples submitted to AGAT Laboratories (AGAT) in Québec. • The same side of the core was consistently sampled to avoid selective sampling bias. • Gold was analysed by fire assay (50 g) with atomic absorption finish, while base metals were analysed by four-acid digestion with ICP-OES finish. All samples received by AGAT were crushed to 90% passing 2 mm mesh sieve. This was then riffle split to a 250 g sample which was pulverised to 90% passing 105 microns. • Samples with gold grades greater than 10 g/t are reprocessed using gravity finish. The processed material is split and analysed by fire assay with ICP- OES finish to extinction. A separate split is prepared to independently analyse mineralized intervals with a target grade greater than 1.00% Cu-Zn using a Na₂O₂ fusion with ICP-OES or ICP-MS finish. • All samples containing visible gold were sent for metallic screen analysis. • These techniques are considered appropriate for the mineralisation expected at all properties. Drilling techniques • Drill type (e.g. core, reverse circulation, open- hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (e.g. 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). • All samples and geological information have been derived from diamond core using standard equipment of NQ size (47.6 mm diameter). • The drill holes were completed by Forage Val d’Or of Québec in 2026. • The drill core was oriented by Forage Val d’Or and verified by Explo-Logik of Québec. Drill sample recovery • 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. • All drill core was measured and compared to actual drilled depths on a run-by-run basis by the company geologist and driller to determine core recovery and Rockmass Quality Data (RQD). Recoveries averaged higher than 98% with the only loss of material coming from the overburden. This horizon is not considered prospective for Lac Gold Limited’s purposes. • Core recovery through the mineralized zones is greater than 98%. • No sample bias was observed. ASX Announcement ASX: LAC | lacgold.com | investors@lacgold.com p18 Criteria JORC Code explanation Commentary Logging • 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. • The total length and percentage of the relevant intersections logged. • All diamond core has been marked up, inspected, logged and photographed by suitably trained and qualified personnel of Explo-Logik. • Logging detail includes depth, hole orientation, lithology, alteration, veining, mineralogy, mineralisation, RQD, magnetic susceptibility and structure. These methods involve a combination of both qualitative and quantitative determinations. • Diamond core was logged in its entirety. Sub-sampling techniques and sample preparation • 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 sub- sampling stages to maximise representivity of samples. • Measures taken to ensure that the sampling is representative of the in-situ 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. • All samples have been derived from NQ diamond core and have been cut in half or quarter using a standard core saw. Foliation is aligned perpendicular to the cut. This technique is considered appropriate for the mineralisation observed at the properties. • Crushing stage duplicates have been submitted to the assay laboratory at a rate of 1:20 to evaluate the sampling technique as per standard industry practise. • Lac Gold has retained and stored all remaining half- core samples for future reference/use. • Sample preparation follows industry best practice standards and is conducted by internationally recognised and certified laboratories. • Quality control samples inserted include field duplicates (1 in 20), standards (1 in 20) and blanks (1 in 50). • Sample sizes are consistent with industry standards and are considered appropriate for the mineralisation. Quality of assay data and laboratory tests • The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. • 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. • AGAT is a certified laboratory (ISO/IEC 17025 accredited) and subject to internal QAQC processes. • AGAT digest processes are considered total and appropriate for this style of mineralisation. • Explo-Logik determined SG values have been derived from whole-sample wet/dry weights using a suitable set of electronic scales as per industry standard practise. • Geophysical tools have not been used. • Field duplicates have been inserted at a ratio of 1:20 samples. • Samples of Certified Reference Material (CRM) for gold and blanks have been inserted into the sample stream at a ratio of 1:20 and 1:50 for respectively. • AGAT is subject to their own internal QAQC determinations. A duplicate sample is generated for crushed samples at a rate of 1 in 50. Another duplicate for pulverised samples is generated at a rate of 1 in 50. • Laboratory instruments are calibrated every 42 samples. • Laboratory blanks (x 2), certified reference materials (x 2) and sample duplicates (x 3) were analysed within every 42 samples in the batch tray. • Explo-Logik has reviewed the QAQC results, and they are considered acceptable. Verification of sampling and assaying • 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. • Results have been reviewed by the Exploration Manager (Competent Person). The data is imported into Micromine software for visual checks and database validation by the Competent Person. • Twinned holes have not been employed as a check to the current program at this stage. • Sample results were imported into the company database following validation checks by Explo-Logik. • All data is electronically logged in Access and stored ASX Announcement ASX: LAC | lacgold.com | investors@lacgold.com p19 Criteria JORC Code explanation Commentary on the Company’s database. A master copy of this data exists on the Lac Gold Limited server in Australia. • No adjustments have been made to the assay data. Location of data points • Accuracy and quality of surveys used to locate drillholes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. • Specification of the grid system used. • Quality and adequacy of topographic control. • The 2026 program of drilling was s
