Vancouver, British Columbia--(Newsfile Corp. - April 8, 2026) - Goldstorm Metals Corp. (TSXV: GSTM) (FSE: B2U) ("Goldstorm" or the "Company") is pleased to announce that the Company has engaged Fathom Geophysics to conduct an independent review of the results of the 2025 geophysical programs, including both Induced Polarization (IP) and Magnetotelluric (MT) surveys completed over the Copernicus Zone at its 100% owned Crown Property (the "Property).

The Copernicus Zone hosts very prospective drill targets within an area measuring approximately 1.2 kilometres north-south by 800 metres (m) east-west, centrally located on the roughly 16,000-hectare Crown Property. The property is strategically located in the Golden Triangle of British Columbia, immediately south of Seabridge Gold's KSM Project and Newmont's Brucejack Mine. Click to view: Crown location map.

Daniel Core of Fathom Geophysics commented on the results of his analysis: "The geophysical data at Copernicus indicate the area has potential for porphyry copper mineralization. The area hosts a 700 m x 400 m chargeability anomaly in relatively resistive rocks on the three westernmost lines, and the anomaly remains open to the west. The magnetic data show that the area is structurally complex at the intersection of NW and NE-trending features, and the IP results indicate a potential buried intrusion on the west side of the IP survey area. A 500-m-long chargeability anomaly on the most eastern line, that is coincident with a magnetic structure, suggests that a second system may be present."

Ken Konkin, P. Geo., President and CEO, stated: "We are pleased to announce the first five proposed drill holes of Phase 1 at the Crown Project. We plan to launch the first set of three HQ and NQ2 drill holes targeting the Copernicus and Orion Spine Porphyry targets as our highest priority (see Figure 1). The holes may be drilled to depths of as much as 800 m to test the extent of the IP chargeability anomalies, and will be wide-spaced in order to fast-track the strongest looking mineralized areas (see Figure 2). In addition to drilling at Orion Spine, we plan to drill the Delta West target, discovered by our reconnaissance crew last season, where a grab sample yielded over 39 g/t gold from a shear hosted quartz vein containing fine-grained pyrite. As well, samples from numerous sub-parallel structures over a 500 m x 800 m gossanous area returned significant gold values. Delta West is located ten kilometers directly south of the Valley of the Kings Gold Deposit at the Brucejack Mine. All proposed drill holes have been plotted on various types of enhanced images that highlight the IP chargeability and geological interpretations completed by our field crews. We have utilized high-resolution WorldView-3 Multispectral Images obtained at the end of the 2025 field season that demonstrate various types of alteration and iron oxidation associated with various styles of mineralization and their associated alteration assemblages (Figure 3). These images have greatly enhanced our geological interpretations and aided in drill targeting. The re-interpretation of all geophysical data also supports the 'Thrust Fault Model' extending southward beyond the Treaty Creek and KSM Deposit models as shown in the cross section below (Figure 2)."

Mr. Konkin Continued: "We thank Mr. Daniel Core for a comprehensive and detailed "next level" analysis of the magnetic and IP data we collected. His interpretation of the historical magnetic data reinforced our understanding of the structural complexity of this part of the Crown claims. The added information has allowed our technical team to plan drill hole orientations and depths that will sufficiently test each intended target. We expect to drill approximately 3,000 meters in the first five holes of our Phase 1 Program. Contingent on results of the preliminary work, a Phase 2 program may include up to an additional 6,000 m of drilling.

Lastly, I am particularly pleased to welcome the addition of the well-known and respected geologist, Joel Ashburner to our team at Goldstorm. I have had the great fortune of working with Joel for several years at Brucejack Lake during the discovery of the Valley of the Kings deposit. We will benefit from his vast and intimate first-hand knowledge and experience of the geology and mineralization throughout the Golden Triangle. Today our geological team has become much stronger!"

Appointment of Joel Ashburner

Goldstorm Metals is pleased to announce the appointment of Joel Ashburner as Chief Geologist. Mr. Ashburner brings over 15 years of experience in the mineral exploration industry and has worked across the full project lifecycle, from grassroots target generation, through advanced exploration, to operating mines. In more recent roles, he has led multi-disciplinary teams focused on mine-outskirt and brownfields exploration at the Brucejack Project in northwest British Columbia, contributing to significant resource growth and mine life extension. Earlier in his career, he was part of the team responsible for the discovery of the Valley of the Kings deposit and later played a key role in the discovery and delineation of the Golden Marmot deposit. He was also instrumental in the discovery and advancement of new resources at Brucejack, contributing to the addition of more than 4 million ounces of gold to the mineral resource. Mr. Ashburner's experience spans projects across British Columbia, Yukon, Ontario and Australia.

Qualified Person

The Qualified Person for this news release for the purposes of National Instrument 43-101 is the Company's President and CEO, Ken Konkin, P.Geo. He has read and approved the scientific and technical information that forms the basis for the disclosure contained in this news release.

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.
