Abbreviations: meters = 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 securely 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, including blanks and certified reference materials and duplicates, 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 is overseen by the Company's Qualified Person, Mathew Ball, P.Geo., Mine Exploration Manager. 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, 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-millimeter (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 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 used the MSA code IMS-230 method to provide multi-element determination using a four-acid digestion followed by ICP-OES and ICP-MS analysis.
