Goldstorm Metals Completes Geophysical & Rock Geochemical Surveys on the Crown Property and Provides Drilling Update on the Electrum Property, located in the Golden Triangle of British Columbia

Vancouver, British Columbia--(Newsfile Corp. - October 9, 2025) - Goldstorm Metals Corp. (TSXV: GSTM) (FSE: B2U) ("Goldstorm" or the "Company") is pleased to provide an update on the 2025 exploration activities at its 100% owned Crown and Electrum Properties, covering over 16,000 hectares directly south of Seabridge Gold's KSM Project and Newmont's Brucejack Mine.

At the Crown Property, the Company successfully completed Induced Polarization (IP) and Magnetotelluric (MT) surveys across the Copernicus Zone, as well as surveying areas of geochemical anomalies along the Orion Spine. Concurrently, our geological crews undertook an extensive rock geochemical program throughout the Crown Property, which included 657 random and select grabs, chip, and channel samples. Some preliminary results from the geochemical program are highlighted in this release.

The Company is also pleased to report that drilling at the Electrum Property is proceeding on schedule and on budget. To date, four drill holes have been completed, with two additional holes remaining before the close of this year's exploration season, which is expected within the next two weeks.

Ken Konkin, P. Geo., President and CEO, comments, "We are very pleased to report the completion of the geophysical phase of exploration on the Crown Project, which has delivered some very promising results from the IP program. The survey outlined a large, coincident conductivity-resistivity anomaly underlying the Orion Spine, including the Copernicus Zone, that is located between 300 and 500 meters in depth. This anomaly extends over 1.2 kms in a north-south direction, and over a kilometer east to west.

Within this IP anomaly, our crews have identified numerous gold, copper and silver showings along the Orion Spine and discovered several new zones of surficial fracture-controlled mineralization along the eastern flank of Orion Spine that may have originated from a larger, intrusive-related source at depth. Given these results, and the strength of the IP anomaly, we believe there is great geological potential for the trend of Treaty-KSM porphyry deposits to continue southwards through the center of our Crown Claims, beneath the Orion Spine.
