GARIBALDI COMPLETES HIGH RESOLUTION AIR-MAG SURVEY OVER HIGH-

GRADE NICKEL-COPPER AND GOLD PROPERTIES AT ESKAY CREEK.

Vancouver, British Columbia, November 19, 2025 - Garibaldi Resources Corp. (TSXV: GGI) (the “Company”

or “ Garibaldi”) is pleased to announce, further to its ne ws release of September 3, 2025, the successful

completion of a 477 line kilometer Aeromagnetic survey over Key priority targets, within the company’s 180

sq. km claim group in the heart of the Eskay Mining District of Northwest British Columbia. The Survey was

completed on September 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-meter survey lines provided

a higher resolution than any previo us 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 centered on the Kilometer 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 diamon d drill holes at E&L by th e exploration team since

discovery hole E&L-17-14 (see news release Dec.8, 2017) grading 8.3%Nickel, 4.3%Copper over 16.75 meters,

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 is comprised of 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 sample d, with up to 249 g/t (8 oz) gold (see news release

Sept.22,2020) amongst the numerous gold and silver Mi n-file 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 fr om 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 Electro-

Magnetic (BHEM) 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 meter (1,500 ft) long Sumitomo adit which contains 3

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 USD per oz.

• 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 CEO 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 sq.km Eskay Claim Group provides

a clear roadmap, to expand the exploration for new discoveries.
