Stewart, British Columbia--(Newsfile Corp. - October 30, 2025) - Decade Resources Ltd. (TSXV: DEC) ("Decade" or the "Company") announces that it has received assay results from sampling on the Bonaparte copper-gold property, located approximately 50km north of Kamloops, B.C., within the Kamloops Mining Division. The Bonaparte mineral claims are located on NTS map sheet 92I/16W and 92P/1W, the centre of the property is located at 50°59'38.61" North longitude and 120°26'11.29" West latitude. There are two reported Minfile Occurrences located on the property consisting of (Bonaparte 092 050) and (JS Molybdenite 092INE178).

The property has different target areas including:

1. Cu/Au/Mo porphyry potential
2. Bulk-tonnage RIRGS target with high grade gold results in historic drilling, trenching, underground exploration**
3. High grade gold-copper veins.

The main area of historic exploration for gold to date was called the "Discovery area". This area is mineral occurrence (MINFILE No. 092P 050) designated by MINFILE as a developed prospect. Mineralization primarily occurs in a series of north-south trending quartz veins hosted mainly by a quartz diorite intrusion. Locally, the quartz veins contain up to several per cent sulphides consisting of pyrite with lesser chalcopyrite, pyrrhotite and molybdenite. Native gold is also evident but generally is associated with silver-grey tellurides.

Quartz-sulphide from the Crow vein in the 1994 bulk sample area showing chalcopyrite with minor pyrite and fine visible gold. The white quartz is prior to the later grey sulphide bearing quartz along fractures in the earlier material.

The sampling was conducted on exposed quartz-sulphide vein material in an open cut, the host quartz diorite intrusive as well as altered and hornfelsed argillite in the contact areas. In addition, samples were taken from 2018 unmarked and non-sampled drill core with quartz stringers piled near the portal, the decline muck material and quartz veining 1 km east of the "Discovery area".

A total of 34 samples were collected as follows: 5 quartz-sulphide samples and 5 samples of quartz diorite wall rocks were collected in the area of the 1994 bulk sample pit. Nine samples of quartz diorite 3 km east of the "Discovery area", 7 samples of hornfelsed argillite, 13 samples of NQ core and 4 samples from quartz stringers located 1 km east of the :Discovery area". Low copper and gold values were obtained except for the quartz with chalcopyrite in the 1994 pit area. It was noted that all samples of quartz diorite contained small amounts of chalcopyrite with analysis showing 0.01 to 0.02 % copper.

Highlights of the sampling is shown below:

The high bismuth and tellurium values indicate a potential for a RIRGS environment **.

The location of the high grade samples from the "Discovery area" are shown in the map and picture below. The "Discovery Zone" covers an area measuring 300m east-west by 350m north-south. At least 9 gold bearing quartz veins have been located to date within this area through historic trenching and drilling. The Company QP has examined all the reported veins prior to reclamation by the previous claim holder and confirms the veins in the following map shown below.

In 1994 a 3,700 metric ton bulk sample of mineralized vein material from surface trenching to a vertical depth of 12.2m from an open cut on the Nutcracker, Owl, Grey Jay and Crow vein systems, with an average grade of 25.4 g/t Au produced 3,160 ounces of gold. In 2010 a small bulk sample from the Crow Vein was shipped to the Kinross Mill in Republic, Washington. The 364-ton sample assayed 16.3 g/t Au (0.475 oz/t Au), yielding 161.95 troy ounces of gold. The above results are both from the BC Minfile and a 43-101 report by R. Kemp. The Company thinks that these results can be relied on.

A historic drill hole, 15-05 located roughly 500m east of the mined area tested a coincident resistivity and Cu-Au soil geochemical anomaly encountering quartz veins in granodiorite similar to those encountered in the "Discovery Zone." Assay results from DDH 15-05 returned 7.88g/t gold, 38.4g/t silver and 0.33% copper over a 1.0m core width. The 1988 soil geochemical surveys along Cooler Creek identified many anomalous Au-Cu soil geochemical anomalies with soil results reporting up to 3,270ppb Au and a rock grab sample of quartz vein material reporting 73.03g/t Au (2.13opt Au). The Company QP has not verified the above results and they should not be relied on. They are included as reference data for exploration potential.

Claim Acquisition

The Company also has staked an additional 1180 ha to cover an area that had historic silt sampling that yielded 1230 ppb gold draining an area east of the 'Discovery area". Exploration by the Company has indicated the presence of quartz diorite in the drainage area that may be responsible for the anomalous results.

Management Commentary

Ed Kruchkowski, President of Decade Resources, stated:

"The Bonaparte Gold project is an exciting addition to the Company portfolio of properties with geological merit. The presence of at least nine (9) gold bearing quartz veins in an area measuring 300m X 350m in size open to extension along strike and to depth where multi ounce gold assays have been intersected in historic drilling presents a large exploration target. The presence of historical copper and gold soil geochemical results extending to the southeast from the "Discovery Zone" approximately 1 km away, where gold in soil results are reported with up to 3,270ppb Au as well as prospecting uncovering a quartz vein float sample which assayed 73.03g/t Au extends the exploration area even farther. Drilling in 2015 as reported in the 43-101 report confirms that additional gold bearing quartz veins can be located outside of the "Discovery Zone" 500m east in the Cooler Creek area."

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, 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.
