DECADE RESOURCES REPORTS MINERALIZED QUARTZ VEINS AND PORPHYRY INDICATORS AT NORTH MITCHELL PROPERTY, GOLDEN TRIANGLE, BC

Decade Resources Ltd. has released the results from a recent reconnaissance program on the North Mitchell property, located approximately seven kilometres (km) north of Newmont's Brucejack mine and east of Seabridge Gold's Iron Cap deposit in the prolific Golden Triangle of British Columbia.

Highlights:

• Observation of multiple gossanous outcrops with strong silicification, iron oxide staining and quartz veining;
• Discovery of grey saccharoidal (sugary) quartz adjacent to white quartz veins, hosting fine-grained sphalerite and galena -- a mineral assemblage commonly associated with gold-silver systems in the Golden Triangle*;
• Identification of porphyritic intrusive rocks (diorite-granodiorite), providing a potential link to a copper-gold porphyry system at depth;
• Collection of multiple chip and grab samples across veined and altered exposures -- assays are pending;
• Observation earlier in the week of a rock sample containing possible chalcocite, suggesting local copper enrichment.

* There is no guarantee that the presence of these minerals implies that similar mineralization will be located on the claims.

Exploration program

The 2025 field program consisted of prospecting, geological mapping and systematic chip sampling across newly exposed outcrops and float trains. Sampling focused on gossanous walls, quartz-veined boulders and altered host rocks. All samples have been submitted to an accredited laboratory for multielement geochemical analysis, including fire assay for gold and ICP-MS (inductively coupled plasma mass spectrometry) for silver, copper, lead, zinc and pathfinder elements.

Results will be reported once received and interpreted. The company has sent a few samples in for rush assaying in order to guide further exploration this season.

Geological context

The North Mitchell property is underlain by Hazelton Group volcanic and intrusive rocks, and cut by north-south-trending structures interpreted to be splays of the Brucejack fault. The new mineralized exposures are located less than three km from Tudor Gold's Perfect Storm zone drill hole PS-23-10, which intersected 102.15 metres (m) of 1.28 grams per tonne (g/t) gold equivalent (AuEq). The presence of sphalerite- and galena-bearing quartz veins, iron oxide alteration, and nearby porphyritic intrusives suggests the potential for an epithermal gold-silver (Au-Ag) system with a porphyry source -- similar to systems that host nearby Iron Cap and Brucejack deposits.

President's comment

"Our 2025 reconnaissance program has identified a highly prospective target area at North Mitchell," said Ed Kruchkowski, president of Decade Resources. "The combination of veining, alteration and sulphide mineralization significantly advances our understanding of the property. We are eager to receive assays and plan follow-up work, including detailed mapping and potential drill targeting."
