ROKMASTER RECEIVES DRILL PERMIT EXTENSION ON DUNCAN LAKE PROJECT

Rokmaster Resources Corp. has provided an update for the Duncan Lake project, located in southeastern British Columbia and steadily advanced by the company for nearly a decade. The project hosts several drill-ready targets for critical metals, primarily zinc mineralization, although there is considerable potential for high-grade silver mineralization as outlined in the news release dated Dec. 12, 2025. The Duncan Lake project is well situated with extensive road access within 180 kilometres (km) of the Trail smelter, one of the world's largest fully integrated zinc and lead smelting and refining complexes.

A two-year extension was granted by the British Columbia Ministry of Mining and Critical Minerals for the Duncan South permit. This multiyear area-based (MYAB) exploration permit covers the No. 3, No. 2 and No. 1 zones, and the underexplored ground between them south of the Duncan mine. These showings were discovered early in the history of the Duncan Lake camp before the focus was concentrated on the Duncan mine, which was developed by Cominco during 1957 to 1960 but never produced.

The southern MYAB permit allows for up to 26 drill sites and 15 trenches over the next two years. The No. 3 and No. 1 zones were subject to trenching and channel sampling during 2025, which returned strong Zn-Pb-Ag (zinc-lead-silver) grades over metre-scale intervals (see news release dated Oct. 16, 2025). The company also holds a separate MYAB permit for the area north of the Duncan mine. Historical drilling, including several drill holes completed by Rokmaster in 2022, has intersected the northern extension of the Duncan anticline. These results indicate higher Zn-Pb-Ag grades compared with those previously intersected at the Duncan mine.

John Mirko, president and chief executive officer, comments:

"Getting a time extension on the Duncan South permit is great news and will allow us to further test this prospective part of the Duncan Lake project. The project is located in the ideal geology and location for huge targets and rapid development of critical metals. As discussed previously, the project also presents strong potential for high-grade silver mineralization that we look forward to investigating."
