VANCOUVER, BC, Dec. 12, 2025 /CNW/ - Rokmaster Resources Corp. (TSXV: RKR) (OTCQB: RKMSF) (FSE: 1RR1) ("Rokmaster" or "the Company") is pleased to provide an update for its 100% owned Selkirk Project, as well as an overview of the silver potential on other projects in the Company's portfolio.
The Selkirk Project is comprised of three properties located north of Revelstoke in southeastern British Columbia (Figure 1). These three properties have been steadily advanced by Rokmaster since 2021 with positive results generated from geological mapping, prospecting, channel sampling, and soil sampling.
Field work completed on the Downie Gold Property in 2025 confirmed the southern end of the previously mapped of a meter-scale pyrrhotite-diopside-garnet skarn horizon which has a strike length of approximately 2.0 km1. Rock grab samples collected from near the northern and southern limits of the FIM skarn horizon returned elevated tungsten and molybdenum results (Figure 2). The Downie Gold Property also hosts Ag-Au-Pb-Zn vein and replacement mineralization in the Melt and KJ Zones where a Multi-year Area Based ("MYAB") exploration permit allowing for drilling is approved until October 2027.
Ten kilometers 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 field work programs conducted between 2021 and 2024 (Figure 3). The Keystone Property also holds a 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 drillholes 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 Pb-Zn deposits (news release dated October 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 g/t Ag2 and developed prior to the recognition of the Pb-Zn mineralization in the district which was discovered later in the 1950's. Recent work by the Company at the Mag Zone, which is presently the only exposed occurrence of Pb-Zn-Ag mineralization on the west limb of the Duncan Anticline, repeatedly returns high silver concentrations in assays (Figure 4).
Rock samples taken on the Big Copper Property from adits, trenches, drill holes, and outcrop exposures distributed along a 4.5 km 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 towards the core of a possible sedimentary Cu-Ag system (Figure 5).
Furthermore, there are several silver-rich epithermal vein occurrences on the Company's Nechako Project with results up to 614 g/t Ag over 1.2 m and 1,001 g/t Ag over 1.0 m, see new releases dated November 24, 2025 and October 1, 2024 respectively.
John Mirko, President and CEO, comments:
"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 field work 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 Cu-Ag mineralization. All these projects have enticing targets, great access, and drill permits in place."
