A total of approximately 25,588 m of drilling has been completed to date as part of the 2025-2026 Drill Program(1), which includes 11,600 m of a planned 60,000 m drilling program as part of 2026 Feasibility Exploration Drill Program (“2026 FS Drill Program”) initiated in March 2026. Assay results are pending for 23 additional drill holes.
Highlights:
Spanish Mountain Gold, President, Chief Executive Officer & Director, Peter Mah, commented: “We are excited to announce the start of the Spanish Mountain Feasibility Study (“FS”) and associated field programs that started in March of this year. Crews have been mobilized to site with two diamond drill rigs focused on infill drilling on the Main deposit and one sonic rig dedicated to groundwater and geotechnical drilling. Additional diamond drill rigs will be mobilized to site in the coming months that will result in regular news flow as assay results are received and reported. The drill results reported in this news release along with previously reported results continue to extend near surface gold mineralization hosted within the Orca Fault Corridor that could potentially enhance the life-of-mine plan in the first 10-years of production.”
Main Deposit Overview
The Main Deposit exhibits two principal mineralization styles. The early-stage mineralization is strata bound mineralization hosted primarily within carbonaceous argillite units, particularly at or near the contact with tuff and greywacke units. This mineralization strikes northwest and dips shallowly to the northeast with gold mineralization commonly associated with fine-grained disseminated and vein pyrite. The late-stage mineralization consists of quartz veins where visible gold is commonly associated with galena, sphalerite and pyrite. The late-stage mineralization typically strikes northeast and dips moderately to steeply west within the Orca Fault Corridor. Late-stage mineralization is best developed in the argillite and tuff/greywacke unit; however, it occurs in all stratigraphic units and crosscuts the early-stage mineralization.
The 2025-2026 Drill Program was designed to test both styles of mineralization with a preferred drill orientation of azimuth 120° and a dip of -60° (drilling toward the southeast). Historic holes oriented vertically or drilled to the northeast or southwest were not the optimal drill orientation to intersect the late-stage mineralization.
Key Findings - 21 Drill Holes
Drill Results
The following drill descriptions are organized from north to south to provide spatial context for the 21 drill holes reported herein. Where multiple holes occur on the same cross-section, they are described together to highlight how each hole relates to its neighbors.
Drill Hole 26-DH-1343
26-DH-1343, collared over 100 m northeast of 25-DH-1307 (Figures 1 and 2), targeted the northeast continuity of the Orca Fault Corridor and intersected 145 m at 0.52 g/t from 56.00 m and 114 m at 0.62 g/t from 87.00 m gold (Table 1). The hole was successful in extending gold mineralization to the northeast and confirmed several northeast trending structural zones hosting gold mineralization within the Orca Fault Corridor. This emerging pattern, which appears to extend to 26-DH-1350 (Figure 1), suggests that the Orca Fault Corridor may define multiple discrete higher-grade mineralized zones, representing a potentially significant upside for mineralization expansion.
Table 1: Assay Results for 26-DH-1343
Drill Hole 26-DH-1346
26-DH-1346 was drilled 35 m southwest of the 25-DH-1282 (Figure 1, Figure 3) where the Orca Fault was initially defined. The hole intersected 167.50 m of 0.52 g/t gold from 19.0 m, including a higher-grade internal zone of 36.80 m at 1.14 g/t gold from 145.70 m with a subset of 11.10 m at 2.36 g/t gold from 167.00 m (Table 2).
Table 2: Assay Results for 26-DH-1346
Drill Hole 26-DH-1350
26-DH-1350, a southwest step-out and the southern expression of the structural trend that was identified in 26-DH-1343 (Figure 1) , intersected 243.32 m at 0.30 g/t gold from 5.68 m, including 115.32 m at 0.57 g/t from 5.68 m and a sub-interval of 106.64 m at 0.61 g/t gold from 14.36 m close to surface, with further higher-grade internal zones of 58.64 m at 0.87 g/t from 26.36 m and 5.0 m at 2.06 g/t gold from 80.00 m (Table 3). Together with 26-DH-1343, these results reinforce the interpretation that continuous, near surface faults are part of the Orca Fault corridor extending from the northeast to the southwest across the Main deposit. Further drilling and structural modelling are required to fully define this NE-oriented domain as a discrete sub-zone within the broader Orca Fault Corridor.
Table 3: Assay Results for 26-DH-1350
Drill Hole 26-DH-1355
26-DH-1355, is located approximately 430 m southwest of the 26-DH-1327 (Figure 1, Figure 4) returned 188 m at 0.47 g/t gold from 142.00 m, including 116.60 m at 0.60 g/t gold from 189.20 m, with a higher-grade internal zone of 38.38 m at 0.73 g/t gold from 199.62 m and a high-grade subset of 16.30 m at 1.11 g/t gold from 289.50 m (Table 4). This hole confirms the continuity of the northeast-southwest trending Orca Fault Corridor over approximately 430 m and within the current 2025 PEA resource pit. Potential for this structure and associated gold mineralization to extend to the southwest of the current resource pit is high and will be tested as part of the 2026 FS Drill Program.

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.
