Mike Buchanan, Vice President Exploration commented, “I am excited to join Spanish Mountain Gold as Vice President, Exploration. Spanish Mountain represents one of British Columbia’s premier gold development opportunities, combining a substantial mineral resource, exploration potential, and the opportunity for higher-grade mineralization to enhance the mine plan through reduced waste stripping and improved project economics.” These drill holes are part of the 2026 Feasibility Drill Program, initiated in March 2026 targeting infill drilling and resource expansion at the Main Deposit. Other drill programs to provide information on condemnation, geotechnical, metallurgy, geochemistry and groundwater will be used to support the Feasibility Study which is targeted for completion in H1 2028. 2026 PEA – Alternate Project Development Plan The 2026 PEA update presents the potential for a larger scale pit with moderate conceptual footprint impacts that would contain approximately 348 Mt of mineralized mill feed at a grade of 0.39 g/t or 4.4 Moz from measured, indicated and inferred mineral resources. As the company works to complete its 60 km 2026 Exploration Drill Program and continues to optimize its mill flowsheet utilizing coarse particle flotation and associated mill throughput enhancements, it expects to assess this alternate case as part of the feasibility study underway (as filed on SEDAR+, November 6, 2026). Peter Mah, President, CEO and Director commented, “We are very encouraged with the ongoing positive drill results reported in recent news releases. We see the potential for an even larger scale gold operation in a region of British Columbia, Canada where jobs and economic opportunities are critically needed to support a vibrant community.” Drill Results (Table 1) Hole From (m) To (m) Length (m)* Gold Grade (g/t Au) 26-DH-1419 28.07 75.00 46.93 0.30 Including 45.90 75.00 29.10 0.43 26-DH-1420 No significant intercepts 26-DH-1421 14.85 153.40 138.55 0.50 Including 16.00 56.70 40.70 1.26 26-DH-1422 47.40 51.83 4.43 0.77 26-DH-1422 161.00 316.00 155.00 0.34 Including 170.00 256.07 86.07 0.43 26-DH-1423 36.00 48.00 12.00 0.30 26-DH-1424 167.00 176.00 9.00 0.36 Including 167.00 168.35 1.35 1.90 26-DH-1425 5.50 21.00 15.50 0.33 26-DH-1425 52.00 109.00 57.00 0.25 26-DH-1425 152.40 222.30 69.90 0.24 Including 152.40 161.00 8.60 0.46 Including 210.50 222.30 11.80 0.92 26-DH-1426 43.00 150.60 107.60 0.21 Including 88.00 91.20 3.20 0.70 Including 145.40 150.60 5.20 0.64 26-DH-1427 5.50 49.00 43.50 0.45 Including 23.90 36.00 12.10 1.01 26-DH-1427 198.30 204.00 5.70 0.64 26-DH-1428 173.46 176.20 2.74 0.98 26-DH-1428 280.58 288.18 7.60 0.69 26-DH-1429 51.00 225.00 174.00 0.29 Including 51.00 94.00 43.00 0.93 Including 138.30 145.85 7.55 0.38 26-DH-1430 108.00 121.65 13.65 0.38 26-DH-1430 212.00 222.00 10.00 0.98 26-DH-1431 68.00 103.35 35.35 0.37 Including 68.00 72.65 4.65 0.82 Including 92.00 103.35 11.35 0.69 26-DH-1432 44.00 263.20 219.20 0.29 Including 44.00 72.00 28.00 0.96 Including 126.00 130.00 4.00 1.16 Hole From (m) To (m) Length (m)* Gold Grade (g/t Au) 26-DH-1433 283.00 287.00 4.00 0.41 26-DH-1433 416.00 418.00 6.67 3.34 26-DH-1434 44.00 285.00 241.00 0.30 Including 44.00 112.00 68.00 0.52 Including 192.00 285.00 93.00 0.36 26-DH-1435 51.30 309.50 258.20 0.29 Including 162.00 309.50 147.50 0.41 26-DH-1436 78.00 82.00 4.00 2.62 26-DH-1436 194.00 256.00 62.00 0.19 26-DH-1438 44.00 239.00 195.00 0.27 including 75.00 162.00 87.00 0.39 26-DH-1439 16.60 28.45 11.85 0.70 Including 118.00 160.00 42.00 0.64 26-DH-1441 58.00 157.86 99.86 0.33 Including 102.00 106.00 4.00 1.39 Including 139.90 154.00 14.10 0.80   *Length is core length: True thickness is not determined.

Abbreviations: metres = m, Collar coordinates Datum: UTM NAD83 Zone 10N Drill Core Processing, Data Verification and Quality Assurance – Quality Control Program (QAQC) Drill core is received daily from the rigs and logged for recovery, RQD, lithology, alteration, mineralization and vein style and intensity before samples are marked for cutting, with core photography being done to capture the marked sample intervals. The entire holes are sampled, with core sawn in half and samples labeled and bagged. The remaining half core is stored on-site. Numbered security tags are applied to sample shipments to ensure chain of custody compliance. The Company inserts quality control (QC) samples at regular intervals to monitor laboratory performance, including blanks, certified reference materials and duplicates. 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 is overseen by the Company's Qualified Person, Michael Buchanan, P.Geo., Vice President Exploration. The data verification process involves a multi-step approach to ensure accuracy and integrity. This includes a detailed quality control (QC) analysis of the data, which is performed using both internal and external platforms, such as the MxDeposit™ software. The QC checks involve monitoring the results of analyses of certified reference materials (CRMs), blanks, and duplicates to confirm the reliability of the assay results. In addition, 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 subsample 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 Photon assaying after conducting 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 MSA code 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 routinely obtains multi-element determinations using a four-acid digestion followed by ICP-OES and ICP-MS analysis (MSA code IMS-230). NSR Buy Back The Company is also pleased to report that it has entered into an agreement (“Buy Back Agreement”) to buy back a portion of the net smelter interest that was originally granted to Robert Mickle (the “Mickle NSR”). The Mickle NSR is a 2.5% net smelter royalty interest on certain claims of the Spanish Mountain Gold Project. Pursuant to the Buy Back Agreement, the Company will acquire in a first closing 25% of the Mickle NSR (i.e., 0.625%) for $755,000, in cash, payable in stages, with the final payment due on July 1, 2030. In a second closing, the Company will acquire the vendor’s additional interest in the Mickle NSR (the exact percentage of which is subject to confirmation from the other parties with an interest in the Mickle NSR) for $5,000, in cash. The first closing is expected to occur on November 10, 2026. Following the purchase of the additional interest from the vendor in the second closing, the Company will have the right to buydown the remaining Mickle NSR royalty to .6875% for $343,750. The second closing will occur on the earlier of receipt of confirmation from all holders of the Mickle NSR of the vendor’s additional interest, the commencement of commercial production at the Project, and July 1, 2030. The vendor is at arm’s-length to the Company.
