Goldstorm Metals Provides High-Grade Gold-Silver-Copper Results from Surface Sampling on the Crown Property, and Drilling Results from the Electrum Property, located in the Golden Triangle of British Columbia.Vancouver, British Columbia--(Newsfile Corp. - November 25, 2025) - Goldstorm Metals Corp. (TSXV: GSTM) (FSE: B2U) ("Goldstorm" or the "Company") is pleased to announce assay results from its 2025 surface sampling program at the Crown Property, situated directly south of Seabridge Gold Inc.'s KSM gold-copper project and Newmont's Brucejack gold mine. This release also includes the 2025 drilling results from the Electrum Property, located immediately north of Scottie Resources' claims, within a well-established mineral trend of past and current gold-silver producers. These include Ascot Resources' Premier Mine to the south and Newmont's Brucejack mine to the north. Figure 1 below shows the locations of both the Crown and Electrum properties within their respective mineral trends in the heart of the Golden Triangle. Figure 2 provides a close-up view of the Crown Project in relation to the Treaty-KSM trend of porphyry gold-copper deposits, as well as the north-south alignment of high grade gold-silver deposits found along the Brucejack Fault.Figure 1 - Crown and Electrum Properties Location MapTo view an enhanced version of this graphic, please visit:https://images.newsfilecorp.com/files/9214/275846_dc1087dfb42d3983_002full.jpgFigure 2 - Treaty-KSM Trend: Host to over 100 million ounces of Gold, 20 billion pounds of Copper and 400 ounces of Silver across six DepositsTo view an enhanced version of this graphic, please visit:https://images.newsfilecorp.com/files/9214/275846_dc1087dfb42d3983_003full.jpg2025 Exploration Program on the Crown PropertyThe 2025 field exploration program at the Crown Property, which has now been completed, included extensive surficial sampling, reconnaissance geological mapping, Induced Polarization (IP) and Magnetotelluric (MT) surveys across the Copernicus Zone, and the collection of Worldview 3 high-resolution satellite imagery. The 2024 and 2025 sampling programs have been instrumental in defining the geological potential of the area and advancing early-stage gold-silver-copper prospects into drill ready targets. Planning of drill sites for the 2026 exploration season will be finalized once the compilation and interpretation of the 2025 geophysical surveys have been completed. All assays have now been received for a total of 657 grab, chip, and channel samples that were collected in 2025. Highlights of the results from the sampling program are shown below.Multiple high-grade gold-silver-copper results include: Sample 121777 assayed 103 g/t gold and 197 g/t silver (select grab)Sample 121767 assayed 71.1 g/t gold and 0.44% copper (select grab)Sample 121776 assayed 19.8 g/t gold over a 0.75m (chip sample)Sample 121778 assayed 1423 g/t silver, 6.09 g/t gold and 0.48% copper (select grab)Sample 122061 assayed 218 g/t silver, 0.62 g/t gold, and 0.45% copper (select grab)Sample 122062 assayed 136 g/t silver, 0.31 g/t gold, and 0.24% copper over 0.50m (chip sample)Results from 2025 Sampling ProgramGeochemical sampling in 2025 continued to discover new precious and base metal occurrences across previously unsampled areas of glacial ablation on the Orion Concession, while expanding upon previously recognized, but untested, mineralized trends such as the Copernicus Zone. Mineralization styles observed at Copernicus, and along the northwest Orion Spine, reflect potential intrusive-related sources at depth. This potential has been supported by the presence of an anomalous magnetic high with coincident resistivity-chargeability anomalies, which were defined by the recent Induced Polarization (IP) and Magnetotelluric (MT) surveys. Many of the high-grade gold and silver results are associated with quartz-carbonate-base metal veins in areas that had limited or no previous sample coverage. These assays include some of the highest gold grades to date such as sample 121777, assaying 103 g/t gold, and sample 121767 assaying 71.1 g/t gold from select grabs, while sample 121776 returned 19.8 g/t gold over a 0.75 m chip sample. Additionally, high-grade silver and base-metal mineralization was observed in an area located more than 1.5 km south of the high-grade gold veins. These samples returned up to 1,423 g/t silver, 6.09 g/t gold, 0.48% copper, 18.6% lead, and 5.21% zinc. Mineralization in this area appears to be primarily hosted in epithermal-style quartz-sulphide veins, within sericite and iron-carbonate altered volcaniclastic sequences, spatially associated with quartz-sericite-pyrite altered syenite dykes.Figure 3 - 2025 Crown Property Concessions and Sample Locations with Gold AssaysTo view an enhanced version of this graphic, please visit:https://images.newsfilecorp.com/files/9214/275846_dc1087dfb42d3983_004full.jpgThe Orion area, centered on the Crown Property, encompasses a complex geologic
