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".
