Goldstorm Completes Planning and Permitting for 2026 Exploration Program at Crown Copper, Gold, Silver Property

Vancouver, British Columbia--(Newsfile Corp. - May 27, 2026) - Goldstorm Metals Corp . (TSXV: GSTM) (FSE: B2U ) (" Goldstorm " or the "Company ") is pleased to announce that final planning and permitting are complete for the Company's 2026 exploration program (the " Program ") at its Crown Property (the " Property "), located in the heart of British Columbia's Golden Triangle. As part of this year's planning process, the Company engaged a Professional Biologist to develop comprehensive wildlife safety procedures. With this work now completed, Goldstorm expects the 2026 exploration season to commence earlier than anticipated. 2026 Exploration at the Crown Property The Company plans to initiate its first-ever drill program on the Crown Property.

The Phase 1 program is expected to consist of approximately 3,000 metres of diamond drilling focused on testing the Copernicus copper-gold geochemical trend, which overlies a 1.2-kilometre-long induced polarization ("IP") chargeability anomaly. As well, initial drill testing will be undertaken at the newly discovered Delta West gold-mineralized zone. Subject to encouraging results from the Phase 1 drilling, the Company intends to proceed with a Phase 2 drill program totaling approximately 6,000 metres.

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. Ken Konkin, P.Geo., President and CEO, commented : "We are excited to commence the 2026 exploration program, particularly the first-ever drill testing of the Copernicus copper-gold porphyry target on the Crown Property.

With the wildlife safety plan now completed, we have the opportunity to begin the 2026 exploration program earlier than expected, should snow conditions allow. I will be visiting the property soon to evaluate the current conditions and determine when personnel, drill pad crews, and members of the technical team can safely and efficiently mobilize to begin the Program."

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.
