Recent Company History

Over the last few months, Decade Resources reported multiple exploration successes and corporate financings. High-grade grab samples at Bonaparte on Oct 30, 2025 and the current North Mitchell results both coincided with positive price reactions. In contrast, the $1,170,000 private placement closing on Nov 24, 2025 and the Bonaparte acquisition on Oct 21, 2025 saw notable declines. This announcement continues a sequence of high-grade sampling updates following new property acquisition and related financings.

Analysis

The stock surged +33.3% in the session following this news. A strong positive reaction aligns with the pattern seen after prior high-grade sampling news, such as the Bonaparte results that preceded a 11.43% move. Historical data shows that exploration success often attracted buying, while financings and acquisitions sometimes pressured the stock. Investors evaluating a surge around this update may weigh the grab-sample nature of results and the early-stage status of North Mitchell against the company’s plan for expanded 2026 drilling.

Key Terms

epithermal, porphyry, sericite alteration, reconnaissance program

4 terms

epithermal technical

"suggests the potential for an epithermal Au-Ag system with a porphyry source"

Epithermal describes a type of mineral deposit formed when hot fluids near the Earth’s surface deposit metals such as gold and silver into cracks and porous rock, often creating concentrated ‘veins’ or pockets. For investors, epithermal deposits matter because they can host high-grade, easily accessible ore that may lower extraction costs and shorten the time from discovery to production, affecting project value and exploration risk.

porphyry technical

"potential for an epithermal Au-Ag system with a porphyry source"

A porphyry is a type of large, underground mineral deposit that contains valuable metals such as copper, gold, or molybdenum, often spread over a wide area. Think of it as a giant underground treasure chest, where the metals are embedded in rock formations. These deposits are important to investors because they can be the source of significant resource extraction projects with the potential for substantial economic returns.

sericite alteration technical

"intense sericite alteration. To view an enhanced version of this graphic"

Sericite alteration is the process where hot, mineral-rich fluids change original rock into a fine, white mica called sericite; it shows that fluids moved through the rock and chemically altered it. For investors, sericite is a useful exploration clue because it often forms around the same hot fluid systems that concentrate metals like gold, copper or molybdenum, so its presence can point geologists toward potential ore zones much like damp ground hints at an underground leak.

reconnaissance program technical

"results from the recent reconnaissance program on the North Mitchell Property"

A reconnaissance program is an organized effort to design, build or operate systems that gather information about targets or environments—such as satellites, drones, sensors or data-analysis networks—so decision makers can see what is happening beyond direct observation. For investors it matters because these programs typically involve large, long-term contracts, significant research and development spending, regulatory and national-security approvals, and potential for steady revenue or costly delays, much like a major infrastructure project that pays off only after years of work.

Stewart, British Columbia--(Newsfile Corp. - December 4, 2025) - Decade Resources Ltd. (TSXV: DEC) ("Decade" or the "Company") reports that it has received the results from the recent reconnaissance program on the North Mitchell Property, located in the Golden Triangle region of northwestern British Columbia. The Property is contiguous to Seabridge Gold's KSM and Snowfield deposits and Newmont's Brucejack Mine, placing it at the epicenter of one of the world's largest concentrations of gold and copper resources.

Highlights of assays for random grab sampling on in-situ quartz stockwork zones and intensely sericite altered volcanic rocks include:

• 116.9 g/t Au, 161 g/t Ag, 3.01 % Pb and 5.6 % Zn.
• 5.73 g/t Au and 12.74 g/t Ag.
• 3.7559 g/t Au and 11.19 g/t Ag.

Note: The samples above were random in nature but do not necessarily represent the metal content in the located source. The Company feels that the high metal content is highly encouraging and further investigation is warranted.

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 presence of sphalerite- and galena-bearing quartz veins, iron-oxide alteration, and nearby porphyritic intrusives suggests the potential for an epithermal Au-Ag system with a porphyry source — similar to systems that host nearby Iron Cap and Brucejack deposits.

The following maps show the location and geology of the property relative to adjoining properties.
