VANCOUVER, British Columbia--(BUSINESS WIRE)--Mar 10, 2026--
Spanish Mountain Gold Ltd. (the " Company " or " Spanish Mountain Gold ") (TSX-V: SPA) (FSE: S3Y) (OTCQB: SPAUF) is pleased to report additional assay results from five exploration drill holes within the Orca Fault target trend that were completed as part of its 2025 Fall Diamond Drill program (“ 2025 Fall Drill Program ”) for the Spanish Mountain Gold (“ SMG ”) project, which is located in the Cariboo Gold Corridor, British Columbia, Canada.

The company has completed approximately 15,034 metres (“ m ”), surpassing the original estimate of drilling of 9,000 to 10,000 m of exploration drilling planned under the 2025 Fall Drill Program, now continuing into 2026. Assays and geochemistry are pending receipt from the laboratory and or reporting from seven additional drill holes completed within the Orca Fault target area.

Key Findings:
Main Deposit – Orca Fault area
Five additional drill holes were collared and successfully completed (see Figure 3) in the Orca Fault target area, 26-DH-1333 (Figure 3 and Table 1), 26-DH-1334 (Figure 2 and Table 2), 26-DH-1335 (Figure 3 and Table 3), and 26-DH-1336 (Figure 2 and Table 4), and 26-DH-1337 (Figure 1, Figure 3, and Table 5). These drill holes continue to confirm and lend confidence to the extent of the Orca Fault target area over 530 m strike length, northwest to southeast, and its geological and structural interpretation within the constraining open pit for the MRE (see July 3, 2025 news release).
The continued intersection of broad zones of higher-grade gold mineralization, such as the thick intersection of gold mineralization in drill hole 26-DH-1337 (Figure 1 and Table 5) reinforces the opportunities for not only enhancing the Orca Fault target understanding but developing favorable structures outward into other areas of the Main deposit while exploring for higher-grade gold mineralization in the near surface, open pit environment, as defined in the recent MRE (see July 3, 2025 news release). Drill hole 26-DH-1337 intersected one of the thickest higher-grade intercepts on the property, grading 0.70 g/t gold from 91.50 m that includes 116.80 m of 1.20 g/t gold with a high-grade subset of 12.20 m of 2.46 g/t gold. All results to date continue to reinforce that tighter exploration drill spacing is unlocking additional mineral potential in the Main deposit as drilling systematically works outward from the Orca Fault target, tracking the higher-grade gold mineralization. These exploration drill holes are presented on drill sections (Figure 1, Figure 2, and Figure 3) that shows the alignment of the higher-grade gold mineralization.

Notes for Table 1 to Table 5:
1) Reported intersections are calculated using a 0.15 g/t Au cut-off grade.
2) The complete assay table is available on the Company’s website
3) True thickness of mineralization is unknown as the project is still at the exploration stage
The integration of assay results from these five exploration drill holes strengthens the overall continuity for the new Orca Fault target and the association of higher-grade mineralization over a strike length of 530 m, northwest to southeast (see Figure 3). Stronger continuity is also now being developed spanning multiple, parallel, adjacent drill sections ranging over 200 m, northeast to southwest, at the widest point along the 530 m, main Orca Fault target trend (see Figure 4).
Figure 4 illustrates the locations for five drill hole results outlined in this news release and the drill holes currently in the assay lab, or in process of being drilled. Drill collar location coordinates are summarized for the 2025 Fall Drill Program in Table 6 at the end of this news release.
Qualified Person
Julian Manco, M.Sc., P.Geo., Director of Exploration with Spanish Mountain Gold, is the Qualified Person as defined under National Instrument 43-101 who has reviewed the technical information in this news release and has approved the content for dissemination.

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 assurance and quality control (QAQC) samples at regular intervals, including blanks and reference materials, for all sample shipments to monitor laboratory performance.
Standards and blanks 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 verified 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 TM 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 TM
The PhotonAssay TM method utilizes gamma ray analysis for gold detection using the Chrysos PhotonAssay TM 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 TM instrument bombards 400- to 600-gram samples contained in sealed containers with gamma rays.
These containers remain sealed throughout the process, preserving the sample for potential further testing. The analysis is performed robotically, with results that integrate into existing laboratory management systems. Each sample is accompanied by a reference disc traceable to a Certified Reference Material (CRM). Both the sample and reference disc undergo gamma ray exposure, with signals detected and analyzed to ensure accurate and reliable results. The method offers a gold detection range from 0.015 parts per million (ppm - lower limit) to 10,000 ppm (upper limit). Quality control includes the use of reference materials and blanks, with all results reviewed by a competent person before reporting.
Spanish Mountain Gold implemented two QAQC methodologies to validate the accuracy of PhotonAssay TM 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). QAQC Testing typically can include the following spot checks: 1) Pulverizing tests to evaluate variability in sample preparation, 2) Cross-analysis at external laboratories using screen metallic method, and 3) Five-cycle radiation testing to identify and calibrate potential variability in gold results with variable radiation intensity.
Multi-Elemental Analysis
For the 2025 drilling campaign Spanish Mountain Gold used IMS-230 method to provide multi-element determination using a five-acid digestion followed by ICP-OES and ICP-MS analysis.
Key Process Steps:
Sample Preparation: Samples are dried and ground to a specific criterion (85% passing 75 microns (μm) for rocks and drill core; 180μm for soils and sediments). A homogeneous 10-gram sample is required. Digestion: Samples undergo sequential digestion with nitric, perchloric, hydrofluoric, and hydrochloric acids, followed by dilution with deionized water.
Analysis: The solution is analyzed via ICP-OES and ICP-MS for multi-element quantification.
Quality Control: The process includes reference materials, blanks, and duplicates, with corrections for spectral interferences and thorough review before final reporting.
