ROKMASTER PROVIDES UPDATE ON SELKIRK PROJECT AND SILVER MINERALIZATION TARGETS ON OTHER PROJECTS

Rokmaster Resources Corp. has provided an update for its 100-per-cent-owned Selkirk project as well as an overview of the silver potential on other projects in the company's portfolio.

The Selkirk project comprises three properties located north of Revelstoke in southeastern British Columbia. These three properties have been steadily advanced by Rokmaster since 2021, with positive results generated from geological mapping, prospecting, channel sampling and soil sampling.

Fieldwork completed on the Downie gold property in 2025 confirmed the southern end of the previously mapped of a metre-scale pyrrhotite-diopside-garnet skarn horizon, which has a strike length of approximately 2.0 kilometres. Rock grab samples collected from near the northern and southern limits of the FIM skarn horizon returned elevated tungsten and molybdenum results. The Downie gold property also hosts silver-gold-lead-zinc vein and replacement mineralization in the Melt and KJ zones, where a multiyear area-based (MYAB) exploration permit allowing for drilling is approved until October, 2027.

Ten kilometres south of the Downie gold property, the Keystone property hosts numerous occurrences of replacement and vein-hosted sphalerite and galena mineralization, which were discovered throughout a large area during fieldwork programs conducted between 2021 and 2024. The Keystone property also holds an MYAB exploration permit allowing for drilling until October, 2027.

The company holds other properties, which also have high potential for silver mineralization. The Duncan Lake project principally features large targets for lead-zinc mineralization. Deposits in the Kootenay Arc with similar mineralization to Duncan Lake were not known to host significant silver mineralization, which led to historical operators often not assaying for silver. In 2022, Rokmaster completed three drill holes north of the historic Duncan mine and intersected broad intervals of elevated silver concentrations within the semi-massive pyrite-sphalerite-galena mineralization defining the No. 7 and No. 8 zones in the east limb of the Duncan anticline (news release dated May 17, 2022). The No. 3 to No. 1 showings were trenched and channel sampled in 2025, which also returned silver concentrations well above the average for Kootenay Arc-type lead-zinc deposits (news release dated Oct. 16, 2025).

The Duncan Lake camp was originally explored for high-grade silver mineralization occurring proximal to the Duncan anticline first discovered between 1890 and 1900. Historical mines such as the Surprise, Lavina and Mag zone were small producers of high-grade silver up to 1,555 grams per tonne silver and developed prior to the recognition of the lead-zinc mineralization in the district, which was discovered later in the 1950s. Recent work by the company at the Mag zone, which is presently the only exposed occurrence of lead-zinc-silver mineralization on the west limb of the Duncan anticline, repeatedly returns high silver concentrations in assays.

Rock samples taken on the Big Copper property from adits, trenches, drill holes and outcrop exposures distributed along a 4.5-kilometre deformation zone contain coincident copper and silver mineralization. Assay results from the 2023 soil sampling program suggest the southern portion of the property is prospective for galena and silver, which may assist in vectoring toward the core of a possible sedimentary copper-silver system.

Furthermore, there are several silver-rich epithermal vein occurrences on the company's Nechako project with results up to 614 grams per tonne silver over 1.2 metres and 1,001 grams per tonne silver over 1.0 metre; see new releases dated Nov. 24, 2025, and Oct. 1, 2024, respectively.

John Mirko, president and chief executive officer, commented: "Rokmaster has assembled a solid land position in southeastern British Columbia over the last decade with the Selkirk, Duncan Lake and Big Copper projects. All three projects show strong potential for critical metals and recent market trends suggest promising opportunities for silver-focused exploration. The limited work on the Selkirk project has returned strong assay results in each successive fieldwork program. The Duncan Lake project offers promising opportunities for substantial silver mineralization, which was overlooked by previous operators who worked under different market conditions than those experienced today. The target for Big Copper is substantial sedimentary copper-silver mineralization. All these projects have enticing targets, great access and drill permits in place."

The technical information in this news release has been prepared in accordance with Canadian regulatory requirements as set out in National Instrument 43-101 and reviewed and approved by Eric Titley, PGeo, who is independent of Rokmaster and who acts as Rokmaster's qualified person.

Corporate update

The company is pleased to announce the appointment of Michael Malana as chief financial officer of the company, effective today, following the resignation of Dennis Cojuco as the company's CFO.

For more than a decade, Mr. Cojuco has served as Rokmaster's CFO, supporting the company through projects around the world and helping guide its growth across multiple jurisdictions and major development initiatives.
