/CNW/ - Rokmaster Resources Corp. (TSXV: RKR) (OTCQB: RKMSF) (FSE: 1RR1) ("Rokmaster" or "the Company") is
pleased to provide an update for the Duncan Lake and Big Copper Projects.
Duncan Lake and Big Copper (CNW Group/Rokmaster Resources Corp.)
Both the Duncan Lake Project and Big Copper Project are located in southeastern
British Columbia
and have been steadily advanced by Rokmaster since 2018.
Both Projects feature road access in favourable regions with the Trail Smelter within 170 km of the Duncan Lake Project and with the mining town of
Kimberley,
BC
around the Sullivan Deposit within 50 km of the Big Copper Project (
Figure 1
).
A five-year Multi-year Area Based Exploration Permit ("MYAB Permit") was recently approved on the
Duncan Lake Project
by the British Columbia Ministry of
Mining and Critical Minerals (
Figure 2
). The MYAB Permit allows for up to 21 drill sites north of the historic Duncan Mine, which was developed by Cominco 1957-
1960. Cominco identified eight mineralized zones but never produced ore from the mine. Between 1989 and 1997, Cominco and Teck Resources completed 12
diamond drillholes approximately 2,000 metres north of the Duncan Mine which intersected strong lead-zinc mineralization in the east limb of the north plunging
Duncan Anticline. Rokmaster completed a small drill program in 2022 by re-entering one of these historic drillholes, which are all now on Rokmaster claims, and
successfully intersected the west limb of the Duncan Anticline and cored a wide interval of Zn-Pb-Ag mineralization in the east limb (see news release dated
May
17
, 2022).
There is also a five year MYAB Permit covering the southern No.3, No.2, and No.1 Zones previously approved on the Duncan Lake Project. These zones were
partially defined in the 1960's by Cominco who completed small trenching programs on surface exposures of massive sphalerite-galena mineralization in the east
limb of the Duncan Anticline. This MYAB Permit allows for 26 drillsites and 15 trenches and while it expired in
August 2025
, an application to extend the end date
on the permit due to a large forest fire which burned the region in 2024. The fire extensively burned throughout the No.2 Zone, No.1 Zone, and the Mag Zone with
good potential for new outcrop exposure. The application to extend the permit was submitted in
April 2025
and is currently in the consultation stage since
June
2025
.
Field work on the Duncan Lake Project in 2025 included trenching at the No.3 Zone and further prospecting and sampling in the Mag Zone (
Figure 3
). This work
followed 2023 sampling which collected 127 soil samples and 22 rock samples
1
. Three of the trenches completed at the No.3 Zone returned high lead and zinc
results with appreciable silver grades over meter-scale widths with channel sampling. An outcrop exposure at the No.1 Zone, approximately 3.1 km south of the
No.3 Zone, was also channel sampled returning 14.64% combined lead and zinc with 6.67 g/t Ag over
4.5 m
(Table 1). More advanced geochemical analysis is
ongoing to assess the germanium, gallium, and indium concentrations in the mineralization.

Notes to Table 1:
1. Widths reported are sampled widths, such that true thicknesses are unknown.
2. All assay intervals represent length-weighted averages.
3. Some figures may not sum exactly due to rounding.
4. Samples were prepared and analyzed by MSALABS in
Langley BC
. After preparation, samples were analyzed for 30 elements including Zn, Pb and Ag by 4-
acid digestion of a 0.2 g subsample with ICP-ES finish (MSALAB ore-grade method ICP-240).
A five year MYAB Permit was recently approved on the
Big Copper Project
by the British Columbia Ministry of Mining and Critical Minerals (
Figure 4
). The
MYAB Permit allows for 20 helicopter-supported drillsites and 4 helicopter pads. A field work program was completed on the Big Copper Project in 2023 which
collected 165 soil samples and 11 rock samples, highlighting anomalous silver values in the southern portion of the Property
2
. The Big Copper Property hosts a
mineralized deformation and alteration front approximately 4.5 km in strike defined by at least three adits, outcrops, seven trenches and several drillholes which
support strong copper-silver mineralization. Mineralized zones are hosted within fine-grained siltstones, argillites and dirty quartzites of the
Creston
formation. The
Creston
formation is correlative with the Revett Formation which hosts several large sedimentary hosted copper-silver deposits and undeveloped occurrences in
northern
Montana
and
Idaho
, including the Spar Lake, Montanore and
Rock Creek
deposits.
John Mirko, President and CEO, comments:
"Having these exploration drill permits in hand provides Rokmaster the flexibility to get right to work on these fantastic projects. We have held and advanced the
Duncan Lake and Big Copper Projects for many years and believe in the high potential for exploration success on both. Zinc and copper are critical elements
which are very important in the current environment, and both projects have an ideal address for a discovery to be made and developed. The elevated silver
concentrations on both projects, particularly on the Duncan Lake Project where the strength and significance of silver may not have been fully recognized, is
what we're excited to test in addition to the increasingly critical elements."
Financing Update
The Company is also pleased to announce that further to its news release on
October 7, 2025
that it has closed the first tranche of the flow-through funding (the
"FT Financing") with the issuance of 11,450,000 FT Units (the "FT Units") at a price of
$0.04
per FT Unit for gross proceeds of
$458,000
(the "First Tranche").
Each FT Unit issued in the First Tranche is comprised of one flow-through common share (the "FT Share") plus one-half (1/2) non-transferable non-flow-through
share purchase warrant (each whole warrant, a "NFT Warrant"). Each NFT Warrant is exercisable to purchase one additional non-flow-through common share of
the Company (the "NFT Warrant Share") at
$0.06
for a period of two years expiring on
October 15, 2027
.
The FT Shares will qualify as "flow-through shares" (within the meaning of subsection 66(15) of the
Income Tax Act
(
Canada
) (the "
Tax Act
"). The gross
proceeds raised from the issuance of the FT Shares will be used by the Company to incur "Canadian exploration expenses" (within the meaning of the Tax Act).
In connection with the First Tranche, the Company paid cash finder's fees of
$14,000
and issued 350,000 finder's warrants (the "Finder's Warrant") with respect
to the sale of FT Units to an arm's length subscriber. Each Finder's Warrant entitles the holder to purchase one additional common share of the Company at
$0.05
for a period of two years expiring on
October 15, 2027
.
The securities issued pursuant to the First Tranche and Finder's Warrants are subject to a four-month and one day hold period expiring on
February 16, 2026
.
