Vancouver, British Columbia--(Newsfile Corp. - July 8, 2025) - Goldstorm Metals Corp. (TSXV: GSTM) (FSE: B2U) ("Goldstorm" or "the Company") is pleased to announce that, following a review of its previous exploration programs and recent copper-gold-silver discoveries at the 100%-owned Crown Property, geological and geophysical programs will be undertaken to advance exploration on the Copernicus Zone. The Crown Property covers approximately 16,000 hectares situated adjacent and due south of both Seabridge Gold Inc.'s KSM gold-copper project and Newmont's Brucejack gold mine. See below to view Crown Property location and concession map.

Centered on the Crown Project within the Orion Concessions, the Copernicus Zone represents a high-grade copper target with associated gold and silver mineralization. Goldstorm is currently analyzing assay results from previous sampling programs on the Property, which could define drill-hole locations for an inaugural diamond drilling program. The Company may initiate a drill program if favourable results are obtained from a detailed geophysical study, which is to be undertaken over the length of the Orion 'Spine', a six-kilometer-long, highly silicified and altered, north-south trending ridgeline that hosts various styles of mineralization. Geophysics will include detailed Magnetotelluric (MT) and Induced Polarization (IP) ground surveys to identify magnetic anomalies, chargeability highs, and co-incident resistivity lows that may be associated with mineralization.

To facilitate potential upcoming drilling on the Copernicus Zone, Goldstorm has completed the construction of several drill pads targeting the north to northwest trending, shear-hosted, massive chalcopyrite lenses that may represent mobilized metals from a deeper source within the Orion Spine.

Ken Konkin, P.Geo., President and CEO, comments: "Our technical team has done an excellent job of compiling the data from the recent discoveries along the Orion Spine. We believe that the mineral showings discovered by our reconnaissance crews over the past two years may be surficial representations of a deeper, larger mineralized zone, similar to discoveries at the KSM and Treaty Creek Au-Cu-Ag porphyry deposits located to the north. It is theorized that metal-rich fluids may have been mobilized along high-angle reverse faults that acted as conduits for volatiles originating from intrusive bodies at depth. The silicification, alteration and oxidation observed at surface is similar to that seen associated with mineralized intrusives dispersed along the trend of the Sulphurets thrust fault to the north, which is projected to extend south through the center of the Crown Property. The geophysical surveys may help determine the best possible drill targets along the Orion Spine that potentially lie beneath the Copernicus Zone. The detailed geophysical surveys will augment previously completed reconnaissance scale surveys done in 2016."

2024 Crown Property Sampling Results

Extensive mapping and sampling programs in 2024 on the Crown Property included a total of 627 surface rock grab, chip and channel samples. On the Orion Concession, crews delineated multiple mineralized trends within volcaniclastic rocks at the Copernicus Zone, located along the upper Orion Spine. Three structures trending to the north, and one trending to the northwest, have been identified over 1,500 m of length. Mineralization located over 500 m to the north suggests that the zone may extend under the Frank Mackie Glacier and is potentially a larger source of mineralization associated with an anomalous magnetic high. At the Cat in the Hat Zone, also on Orion, gold-bearing veins trending northeasterly within rhyolitic rocks have been discovered, extending into previously unsampled glacial ablation zones.

Sampling highlights from the Copernicus and Cat in the Hat Zones include:

• Grab sample (C969903) returned 30.9 g/t gold and 42.39 g/t silver from the Cat in the Hat Zone
• 1.9-meter continuous chip samples (C969719 and C969720) returned 2.53 g/t gold, 54.7 g/t silver and 3.3% copper located 290 meters south of the original Copernicus showing
• 1.0-meter chip sample (C970612) returned 8.76 g/t gold and 7.62 g/t silver located 650 meters south of the original Copernicus showing
• 16 samples taken within the Copernicus Zone returned greater than 1% copper, with one sample (C969842) assaying 0.58 g/t gold, 625 g/t silver, and 6.57% copper at the original Copernicus showing
• Mineralized samples were found to correlate with a magnetic high geophysical anomaly

QA/QC

All samples were prepared at MSA Labs' Preparation Laboratory in Terrace, BC and assayed at MSA Labs' Geochemical Laboratory in Langley, BC. Gold was assayed using a fire assay with atomic absorption (AA) spectrometry finish. Samples over 10 ppm gold were fire assayed with gravimetric finish. All samples were analyzed by four acid digestion with multi-element ICP-MS, with silver and base metal over-limits 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.
