Goldstorm defines drill targets at Crown property

Mr. Ken Konkin reports GOLDSTORM METALS GEOPHYSICAL SURVEYS DEFINE NEW EXPLORATION DRILL TARGETS ON THE 100% OWNED CROWN PROPERTY, LOCATED IN THE GOLDEN TRIANGLE OF BRITISH COLUMBIA Goldstorm Metals Corp. has provided an updated analysis of the results of the 2025 geophysical programs, including both the induced polarization (IP) and magnetotelluric (MT) surveys, with incorporation of the geochemical surveys completed at its 100-per-cent-owned Crown property. The property covers approximately 16,000 hectares directly south of Seabridge Gold's KSM project and Newmont's Brucejack mine. Ken Konkin, PGeo, president and chief executive officer, comments: "This year's IP and MT programs have significantly improved our understanding of the structural framework at the Crown project -- a key factor in interpreting the overall mineral potential as currently defined by surface mineralization along the Orion Spine. When combined with data from the geochemical program, the results provide important subsurface information for planning future drill programs across multiple high-priority gold, copper and silver targets. "The geophysical results suggest the presence of a large, intrusive body at depth, which may be the source of mineralized veins seen at surface. This reinforces both our current exploration model and the geological connection between the Crown project, Treaty Creek (Tudor Gold) and the KSM (Seabridge Gold) porphyry systems. Together these systems form a 20-kilometre-long, north-trending mineral belt hosting resources of over 100 million ounces gold, 20 billion pounds of copper and over 400 million ounces of silver. The combined survey results increase our confidence in the potential for discovering a very large intrusive-related copper-gold-silver porphyry system. The favourable geophysical and geochemical results define an area measuring 1.2 km in a north-south direction, and over a kilometre east to west. A silica-rich resistive ridge at surface, a chargeability anomaly beneath it and a deep MT low below that are features of a classic porphyry architecture. These would represent the silicified lithocap, the sulphide shell and the deep alteration/fluid system. That's exactly the kind of geometry you want to see when hunting a porphyry deposit. "The Orion Spine area is now drill ready and we will be assessing the best options for drilling the priority co-incident anomalies. We plan a minimum of 2,400 to 3,000 metres of HQ and NQ core in at least six drill holes for phase 1. Contingent on the success of phase 1, an additional proposed 5,000 to 6,000 metres of drilling may proceed for phase 2. We will release the drill plan once targets are finalized and the budget and logistics are confirmed for the proposed 2026 exploration program." Mr. Konkin continued: "In addition to delineating numerous high-priority geophysical targets, our 2025 exploration year's highlight was the discovery of a new gold zone located 10 kilometres south of Brucejack Mines' Valley of the Kings deposit. The new discovery, now known as Delta West, consists of a series of structurally controlled, subparallel, gold-bearing quartz-pyrite veins and stockwork systems trending east-northeast, similar to the trends observed at Treaty Creek's Supercell complex. Exploration crews will target this 500 m by 800 m area with the focus on expanding the zone eastward, where more gossanous host rocks have been observed from the air. This area has only recently been exposed due to the rapid ablation of snowfields and glaciers. These mineralized structures are located much higher in elevation than the known porphyry deposits occurring to the north at KSM and Treaty Creek. We believe that these gold-bearing structures may represent the outer reaches of a deep-seated intrusive-related or porphyry system." Highlights of the IP and MT geophysical programs include: Identification of multiple, large-scale, high-chargeability and low-resistivity anomalies coincident with previously identified zones of copper, gold and silver mineralization along the Orion Spine, where the potential exists for a mineralizing intrusive source at depth. Delineation of a coincident chargeability-resistivity anomaly at the Copernicus zone, situated between 300 and 500 metres in depth and extending over 1.2 km north to south and over one km east to west, where recent exploration efforts have returned significant copper-gold-silver assay results. Mapping of subsurface MT resistivity variations, to depths exceeding 2,500 metres, enhancing the understanding of potential sources and deep-rooted structures related to the hydrothermal mineralization (note that low resistivity equates to high conductivity, often due to the presence of metallic minerals). Prioritization of seven conductive zones: four first priority and three second priority. Identification of 26 chargeability anomalies: 15 first priority, eight second priority and three third priority targets. Note the similarities between the size and intensity of the MT conductivity anomalies (resistivity lows) that underlie the Orion Spine at the Crown property and the MT anomaly beneath the Goldstorm deposit at Treaty Creek owned by Tudor Gold Corp., the parent company of Goldstorm Metals Corp. Warrant acceleration Goldstorm also announces that it is providing notice regarding the acceleration of the expiry of outstanding common share purchase warrants of the company that were originally issued on June 27, 2025 (see news release dated June 27, 2025). Pursuant to the terms of the warrants, the expiry date of the warrants accelerates if the closing share price on the TSX Venture Exchange exceeds 20 cents for any 10 consecutive trading days during the unexpired term of the warrants, resulting in a new expiry date that is 30 calendar days after the date the company issues notice to the warrant holders. The company hereby provides notice on Dec. 15, 2025, of the acceleration period covering the 10 trading days between Oct. 10, 2025, and Oct. 24, 2025, which has triggered the acceleration of the expiry of the warrants to 4:30 p.m. (Vancouver time) on Jan. 15, 2026. Any warrants remaining unexercised after the accelerated expiry date will expire and be of no force and effect. Qualified person The qualified person for this news release for the purposes of National Instrument 43-101 is the company's president and chief executive officer, Ken Konkin, PGeo. He has read and approved the scientific and technical information that forms the basis for the disclosure contained in this news release. QA/QC (quality assurance/quality control) All samples were prepared at MSA Labs' preparation laboratory in Terrace, B.C., and assayed at MSA Labs' geochemical laboratory in Langley, B.C. Gold was assayed using a fire assay with atomic absorption (AA) spectrometry finish. Samples over 10 parts per million gold were fire assayed with gravimetric finish. All samples were analyzed by four-acid digestion with multielement ICP-MS, with silver and base metal overlimits being reanalyzed by emission spectrometry. MSA Laboratories quality system complies with the requirements for the International Standards ISO 17025 and ISO 9001. MSA Labs is independent of the company. About Goldstorm Metals Corp.
