The figure illustrates the collar locations for all 7 drill holes reported in this news release, plus holes with assays pending. Section lines correspond to drill cross-sections presented in Figures 2, 3, and 4. Collar coordinates are summarized in Table 5. The assay results from these drill holes are part of the 2026 Feasibility Drill Program, which was initiated in March 2026 with the objective of increasing resource confidence (infill drilling) and expanding on the current mineral resource. Approximately 17,143 metres (“m”) of a planned 60,000 m drilling program has been completed to date. This news release presents results for holes 26-DH-1374 to 26-DH-1380. Assay results are pending for 19 additional drill holes. Highlights: 26-DH-1376, collared 75 m northeast of 26-DH-1363, returned 303.18 m of 0.50 g/t gold from 76.02 m, including 80.15 m of 0.83 g/t gold from 205.0 m with a higher-grade subset of 27.2 m of 1.92 g/t gold from 242.8 m, cross-cutting multiple Orca-style higher-grade structures on the western side of the Main Deposit. 26-DH-1379, collared 50 m northeast of 26-DH-1376, intersected three separate Orca-style mineralization zones, including a broader interval of 107.0 m of 0.56 g/t gold from 221.0 m with a higher-grade subset of 53.1 m of 0.85 g/t gold from 270.9 m. 26-DH-1378, collared 210 m southeast of 26-DH-1359, intersected 60.65 m of 0.93 g/t gold from 39.55 m and encountered mineralization in the southern part of the deposit between Fault 2 and Fault 3, within the Years 5–10 life-of-mine shells. 26-DH-1375 and 26-DH-1377 extending the Orca Fault Corridor on the eastern margin of the main deposit returned near-surface mineralization starting from 90.2 m and 15.0 m, respectively. 26-DH-1375 intersected 95.0 m of 0.40 g/t gold from 49.0 m, including 34.8 m of 0.78 g/t gold from 90.2. 26-DH-1377 intersected 135 m of 0.32 g/t gold from 15.00 m including 81.25 m of 0.40 g/t gold from 38.5 m. Key Findings - 7 Drill Holes The drilling in the western side of the deposit - tested by 26-DH-1374, 26-DH-1376, and 26-DH-1379 (Sections A-A’ and B-B’) crosscuts multiple higher-grade zones associated with the Orca Fault Corridor, with results confirming structural continuity from near surface to over 370 m depth. The southern part of the Main Deposit - tested by 26-DH-1378 (Section C-C’), collared 210 m southeast of 26-DH-1359 - encountered gold mineralization between Fault 2 and Fault 3, within the Years 5–10 life-of-mine shells defined in the 2025 Preliminary Economic Assessment (see news release from July 3, 2025). The eastern part of the Main Deposit - tested by 26-DH-1375 and 26-DH-1377 - continues to deliver higher-grade near-surface mineralization relative to the 2025 MRE (see news release from July 3, 2025) starting from 15.0 m (26-DH-1377) and 90.2 m (26-DH-1375), helping to delineate the structural controls interpreted as part of the Orca Fault Corridor at the eastern margin of the Main Deposit. Higher-grade subsets including 27.2 m of 1.92 g/t gold from 242.8 m (26-DH-1376), 53.1 m of 0.85 g/t gold from 270.9 m (26-DH-1379), and 60.65 m of 0.93 g/t gold from 39.55 m (26-DH-1378) are consistent with Orca-style vein clusters and reinforce the structural model across all three drilled areas.

Maximum inclusion of 20 consecutive metres below cut-off grade. 2) The complete assay table is available on the Company’s website. 3) True thickness of mineralization is unknown as the Company is still conducting exploration and development drilling while undertaking its feasibility study. Drill Core Processing, Data Verification and Quality Assurance – Quality Control Program (QAQC) Once received from the drill and processed, all drill core samples were sawn in half, labeled, and bagged. The remaining half of the drill core was securely stored on-site. Numbered security tags were applied to sample shipments to ensure chain of custody compliance. The Company inserts quality control (QC) samples at regular intervals, including blanks and reference materials, for all sample shipments to monitor laboratory performance. Standards, blanks, preparation and field duplicates account for a minimum of 20% of the samples in addition to the laboratory's internal quality assurance programs. The QAQC program was overseen by the Company's Qualified Person, Julian Manco, P.Geo., Director of Exploration (as described below). The data verification process involved a multi-step approach to ensure accuracy and integrity. This included a detailed quality control (QC) analysis of the data, which was performed using both internal and external platforms, such as the MxDeposit™ software. These QC checks involved the analysis of certified reference materials (CRMs), blanks, and duplicates to confirm the reliability of the assay results. In addition, a field inspection of the specific drill intervals mentioned in this release has been conducted to directly observe the geological features and verify the nature of the results presented. Drill core samples were submitted to MSALABS's analytical facility in Prince George, British Columbia, for sample preparation and PhotonAssay™ analysis. The MSALABS facilities are accredited to the International Standards ISO/IEC 17025 and ISO 9001 standard for gold and multi-element assays, with all analytical methods incorporating quality control materials at defined frequencies and established data acceptance criteria. MSALABS Inc. is independent of the Company. PhotonAssay™ The PhotonAssay™ method utilizes gamma ray analysis for gold detection using the Chrysos PhotonAssay™ instrument (PA1408X). This non-destructive, fully automated technique offers high accuracy for analyzing ores and pulps. Sample preparation begins with drying and crushing up to 1 kg of material to achieve at least 70% passing through a 2-millimetre (mm) sieve. The sample is then riffle split to obtain a suitable aliquot for 2 testing cycles (MSALABS Method CPA-Au1). The PhotonAssay™ instrument bombards 400- to 600-gram samples contained in sealed containers with gamma rays. Each sample is accompanied by a reference disc traceable to a Certified Reference Material (CRM). The method offers a gold detection range from 0.015 ppm (lower limit) to 10,000 ppm (upper limit). Spanish Mountain Gold implemented two QAQC methodologies to validate the accuracy of PhotonAssay™ results, both demonstrating good comparability: 1) comparative analysis of diverse mineralization styles using Total Au screen metallic methods with both FAS-415 (gravimetric finish) and FAS-211 (AAS finish), and 2) comprehensive testing of both sample aliquots and rejects using FAS-211 (AAS finish). Multi-Elemental Analysis For the 2026 drilling campaign, Spanish Mountain Gold used the IMS-230 method to provide multi-element determination using a four-acid digestion followed by ICP-OES and ICP-MS analysis.
