Vancouver, British Columbia--(Newsfile Corp. - July 15, 2026) - Goldstorm Metals Corp. (TSXV: GSTM) (FSE: B2U) ("Goldstorm" or "the Company") is pleased to report that a diamond drill program has commenced (the "Program") on its 100% owned Crown copper-gold-silver property (the "Property"), located within the Golden Triangle region of British Columbia. Crown is situated to the south of Newmont Corporation's Brucejack Mine and Seabridge Gold Inc.'s KSM Property, an area host to over 80 million ounces of gold and over 20 billion pounds of copper.

The Phase 1 part of the Program is expected to consist of approximately 3,000 metres of diamond drilling and will begin with three drill holes focused on testing the Copernicus copper-gold geochemical trend, which overlies a 1.2-kilometre-long induced polarization ("IP") chargeability anomaly. Drill testing will also be undertaken at the recently discovered Delta West gold-mineralized zone, with a minimum of two drill holes targeting shear hosted gold and silver mineralization. Based on encouraging results from the Phase 1 drilling, the Company intends to proceed with a Phase 2 drill program totaling approximately 6,000 metres.

Ken Konkin P. Geo., President and CEO comments: "We are excited to commence the Company's first-ever drill program at the Crown Project. The initial phase will consist of three HQ- and NQ2-size drill holes targeting the Copernicus and Orion Spine porphyry targets (Figure 1). These holes will be drilled to depths of up to 800 metres to test the extent of the large IP chargeability anomalies. The widely spaced drill holes have been strategically designed to efficiently evaluate the strongest surface mineralization and coincident geophysical targets (Figure 2). In addition to the Orion Spine target, we plan to drill the Delta West Zone, located approximately 10 kilometres directly south of the Valley of the Kings Gold Deposit at the Brucejack Mine. Delta West was discovered by our reconnaissance team during the 2025 field season. A grab sample from a shear-hosted quartz vein containing fine-grained pyrite returned greater than 39 g/t gold and follow-up prospecting identified numerous sub-parallel mineralized structures across a 500 m by 800 m gossanous area, with multiple samples returning significant gold values.

The drill holes planned for this program have been designed to test priority targets generated through the integration of IP chargeability data, enhanced geophysical imaging, and detailed geological interpretations completed by our field crews. To further refine our geological model and drill targeting, our technical team also incorporated high-resolution WorldView-3 multispectral imagery acquired at the end of the 2025 field season. These images highlight alteration patterns and iron oxidation associated with various styles of mineralization and their related alteration mineral assemblages (Figure 3). Our comprehensive reinterpretation of the geophysical and geological datasets also provides additional support for the "Thrust Fault Model", which suggests that the thrust-associated mineral systems found at the Treaty Creek and KSM deposits may extend southward onto the Crown Property, as illustrated in the cross section shown in Figure 2."

In addition to drilling activities, Goldstorm plans to further expand the Delta West discovery through continued prospecting, geological mapping, and sampling programs targeting multiple parallel, high-grade, gold-bearing, shear-hosted veins. The Company also intends to conduct prospecting, mapping and sampling programs across the Electrum, Fairweather and Delta claims ("EFD Trend"), in areas that have returned high-grade gold and ultra-high-grade silver values from historical prospecting and sampling programs.

Further to the Company's news release dated May 27, 2026, which disclosed the terms of the advisory agreement (the "Advisory Agreement") entered into with Research Capital Corporation ("RCC"), the Company announces a revised total compensation payable to RCC under the Advisory Agreement. The news release previously disclosed that the Company expected to compensate RCC by payment of $35,000 and issuance of 175,000 share purchase warrants; however, RCC and the Company have agreed to revise the total compensation payable to RCC to a total of $42,000. No share purchase warrants will be issued to RCC. All other terms of the Advisory Agreement remain as previously disclosed.

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.
