Goldstorm Metals Completes 2026 Exploration Program in Crown Property

Goldstorm Metals Corp. has completed its 2026 Exploration Program on its 100%-owned Crown copper-gold-silver property, located in British Columbia's Golden Triangle. The program, which included diamond drilling and reconnaissance rock sampling, tested a portion of the Copernicus copper-gold-silver geochemical trend. This trend coincides with a 1.2-kilometre-long induced polarization ("IP") chargeability anomaly, a compelling exploration target at depth.

The 2026 diamond drilling program comprised seven holes totaling 4,155.5 meters, extending the Copernicus drilling program into the first week of October.

The reconnaissance rock sampling program involved the collection of 526 samples from multiple areas across the Crown Property, primarily on the Delta, Mackie West, and High North concessions. Analytical results have been received for 310 samples, with selected highlights presented. Results for the remaining 216 samples are expected shortly and will be reported by the company once received, reviewed, and interpreted.

Preliminary highlights from the 2026 surface sampling campaign include 25 rock samples that returned greater than 0.5 g/t gold, including 16 samples greater than 1 g/t gold, and 6 samples greater than 5 g/t gold. The company's technical team believes that the high-grade precious metal mineralization may be associated with a low to intermediate sulphidation system emanating from the thrust fault complex that trends south from the large, bulk-tonnage, Treaty Creek and KSM systems.

At the Delta West Zone, sampling confirmed and expanded the high-grade gold system discovered in 2025. Re-sampling of last year's discovery yielded 40.4 g/t gold from a 60 cm-long chip sample, verifying the previously reported 39.9 g/t gold. Also, a 60 cm chip sample grading 22.7 g/t gold was obtained approximately 25 meters along strike, placing Delta West high on the list of targets to drill for 2027.

Samples collected from the northwestern corner of the Mackie West area revealed a polymetallic system with substantial high-grade mineralization of up to 409 g/t silver and 8.02% copper, as well as up to 3.7 g/t gold. Finally, the central portion of the Delta Claim produced a string of gold values along parallel north-northwest structures that are located along a well-documented gold-silver trend that extends northward to the Brucejack Lake deposits. Values of up to 7.45 g/t gold were obtained over 0.5 meters widths of shear-hosted semi-massive to massive sulphide pods. Gold-bearing mineralization was collected within a gossanous area of 600 meters by 200 meters, yielding 11 samples returning over 1 g/t gold. Reconnaissance work will continue in 2027 to expand the mineralized structures and gather geological data for each target before potential drill testing to evaluate continuity at depth.
