Visible gold (VG) was observed in multiple drill holes, confirming the high-grade nature of the K Zone Target (See Figure 3)
Julian Manco, Spanish Mountain Gold's Director of Exploration commented, "These exceptional results validate our new geological model, extend mineralization and highlight the significant potential for more high-grade mineralization within our project area. The high grades encountered in hole 25-DH-1286 are truly remarkable and demonstrate an extraordinary upside potential for the Spanish Mountain Gold project."
Peter Mah, Spanish Mountain Gold's President, CEO and Director commented, "We are thrilled to take a major leap forward unlocking near surface high-grade gold intercepts that support the growing understanding of our high-quality deposit and signal exciting new possibilities for high grade open pit gold discovery within 200 m of surface"

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 and blanks account for a minimum of 15% 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).
Drill core samples were submitted to MSALABS' analytical facility in Prince George, British Columbia, for sample preparation and PhotonAssayTM 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.
PhotonAssayTM
The PhotonAssayTM method utilizes gamma ray analysis for gold detection using the Chrysos PhotonAssayTM 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 PhotonAssayTM instrument bombards 400 - 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 PhotonAssayTM 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) Four-cycle radiation testing to identify and calibrate potential variability in gold results with variable radiation intensity.
To effectively manage the nugget effect on high-grade gold samples MSALABS tested samples to "extinction" (CPA-Au1E method). This approach divides samples into multiple splits, analyzes each separately using PhotonAssayTM, and then calculates a weighted average of the results. By testing various portions of the sample independently and combining their values proportionally, this method provides significantly more representative gold values than traditional single-split analysis for samples with a large nugget effect.
Multi-Elemental Analysis
For the 2025 drilling campaign Spanish Mountain Gold used IMS-230 method to provide multi-element determination using a four-acid digestion followed by ICP-OES and ICP-MS analysis.
Key Process Steps:
Sample Preparation: Samples are dried and ground to specific criteria (85% passing 75 microns (?m) for rocks and drill core; 180?m 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.
Julian Manco, M.Sc., P.Geo., has verified the data disclosed in this news release. 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, Mr. Manco, conducted a field inspection of the specific drill intervals mentioned in this release to directly observe the geological features and verified the nature of the results presented.
