GARIBALDI COMPLETES HIGH RESOLUTION AIR-MAG SURVEY OVER HIGH-GRADE NICKEL-COPPER AND GOLD PROPERTIES AT ESKAY CREEK

Further to its news release of Sept. 3, 2025, Garibaldi Resources Corp. has successfully completed a 477-line-kilometre aeromagnetic survey over key priority targets within the company's 180-square-kilometre claim group in the heart of the Eskay mining district of northwestern British Columbia. The survey was completed on Sept. 18, 2025, by Pioneer Exploration Consultants Ltd. on time and on budget.

The survey covered the areas over the flagship E&L discovery at Nickel Mountain and the Casper high-grade gold quartz-vein discovery north-northwest of Nickel Mountain. The 25-metre survey lines provided a higher resolution than any previous survey. The data reveal in graphic detail the magnetic trends and anomalies around E&L and Casper. The preliminary results over E&L will be further evaluated by inversion processing to build on a previous case study of E&L by Mira Geosciences. Mira's original work identified three strong magnetic anomalies centred on the kilometre-wide O anomaly. The high-resolution magnetic survey now supports the presence of four magnetic anomalies immediately south of E&L.

The E&L critical metals and the Casper high-grade gold quartz vein discoveries are deemed to be the highest-value projects by management. Analysis of 102 diamond drill holes at E&L by the exploration team since discovery hole E&L-17-14 (see news release dated Dec. 8, 2017), grading 8.3 per cent nickel and 4.3 per cent copper over 16.75 metres, reinforces this evaluation. Furthermore, the exploration team's focus on advanced geophysical techniques was affirmed by the new magnetic survey data, which bolsters confidence in the exceptional potential to expand the scale of the E&L mineralization through new discoveries along trend of the E&L and the deeper eastern extension.

A plan of action to advance both the E&L and Casper projects will rely on new geological and geophysical modelling designed to detect mineralization as follows.

E&L mineralization comprises a suite of nickel, copper, cobalt, platinum, palladium, gold, silver and platinum group elements, including rhodium, an uncommon suite of critical metals and precious metals.

Casper is the highest-grade gold prospect yet sampled, with up to 249 grams per tonne (eight ounces) gold (see news release Sept. 22, 2020) amongst the numerous gold and silver Minfile showings recorded by the British Columbia Geological Survey within the Palm Springs portion of the company's larger Eskay claim group. Casper is proximal to some of the largest undeveloped gold and copper-gold deposits in the world.

Recognizing the tremendous potential of both the E&L and Casper projects, the exploration team is investigating several new technologies to improve exploration success; these include the following:

• Advanced inversion processing on the high-resolution aeromagnetic survey data;
• Integration of geological and geochemical data from surface and borehole samples to support the interpretation of the magnetic data;
• Applications of new modelling of the volume and shape of conductive targets for off-hole electromagnetic (borehole electromagnetic) responses;
• Evaluation of the most advanced geological and geophysical exploration techniques with proof of concept and a cost-effective profile, such as muon tomography;
• Examining the potential utilization of the 500-metre-long (1,500-foot-long) Sumitomo adit, which contains three separate drilling station galleries proximal to the E&L intrusion, for drilling and as a platform for geophysical surveys;
• Preparing for the next phase of exploration at the Casper high-grade gold quartz vein discovery now elevated in priority since the gold price breached $4,000 (U.S.) per ounce;
• Casper exploration will use the new magnetic data to better establish the controls on mineralization along the Casper corridor and expand the development of new drill targets.

Steve Regoci, Garibaldi's chief executive officer, stated: "The exploration teams extensive investigative efforts analyzing the geochemical fingerprint and geophysical footprint of E&L and Casper to develop new drill targets is noteworthy. Their evaluation of the potential within the company's 180-square-kilometre Eskay claim group provides a clear road map to expand the exploration for new discoveries.
