DECADE RESOURCES REPORTS UP TO 116.9 G/T GOLD IN GRAB SAMPLING AT THE NORTH MITCHELL PROPERTY, GOLDEN TRIANGLE, BC

Decade Resources Ltd. 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 grams per tonne (g/t) gold (Au), 161 g/t silver (Ag), 3.01 per cent lead (Pb) and 5.6 per cent zinc (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.

During the 2025 reconnaissance program, a total of 63 bedrock and float samples of mineralized rocks were collected across the entire claim. Values varied from less than 0.005 to 116.9 g/t Au, 0.01 to 161 g/t Ag, two parts per million (ppm) to 1.353 per cent Cu, 0.8 ppm to 3.01 per cent Pb and three ppm to 5.6 per cent Zn. The attached table shows values more than one g/t Au.

All samples listed in the table were random grabs from bedrock sources in the area of reported rush samples released in an Oct. 15, 2025, news release. Samples were from a zone of quartz stockwork located in the vicinity of 427168E, 6267078N, all within 50 metres (m) of the GPS (Global Positioning System) reading. The width of the stockwork has not been determined.

Expanded exploration program

Based on the positive results obtained in the 2025 reconnaissance program, the 2026 field program will be expanded to carry out the following:

• Sawcuts across quartz-sulphide-bearing zones to determine mineralization width;
• Short Shaw drill holes to check the gold-silver tenor of any mineralized zones.

Diamond drilling will begin upon receipt of permits and as conditions allow.

President's comment:

"The 2025 reconnaissance program was highly successful in identifying a prospective target area at the North Mitchell property. The presence of all the surrounding mineral deposits in conjunction with the company results on the property indicates a huge potential," said Ed Kruchkowski, president of Decade Resources. "We are eager continue exploration in 2026."

Cautionary statement

Sampling results reported herein are selective in nature and may not represent the true grade or extent of mineralization on the property. Comparisons with adjacent deposits are provided for geological context only and may not indicate that similar mineralization occurs on the North Mitchell property. Mineral resources that are not mineral reserves do not have demonstrated economic viability. Inferred resources are considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as mineral reserves.

All samples were prepared at MSA Labs' preparation laboratory in Terrace, B.C., and assayed at MSA Labs' geochemical laboratory in Langley, B.C. Gold was assayed using a fire assay with atomic absorption (AA) spectrometry finish. Samples over 25 parts per million gold were fire assayed with gravimetric finish. All samples were analyzed by four-acid digestion with multielement ICP-MS (inductively coupled plasma mass spectrometry), with silver and base metal overlimits being reanalyzed by emission spectrometry. MSA Labs' quality system complies with the requirements for the international standards ISO 17025 and ISO 9001. MSA Labs is independent of the company.
