/CNW/ - Rokmaster Resources Corp. (TSXV: RKR) (OTCQB:
RKMSF) (FSE: 1RR1) ("
Rokmaster
" or the "
Company
") is pleased to announce initial assay results
from diamond drilling on the Duncan Lake Zinc Project. An initial drilling campaign was completed in
early
April 2022
with the purpose of confirming historical drill intersections as well as providing
valuable geological information.
Duncan Lake 2022 Drill Program (CNW Group/Rokmaster Resources Corp.)
Three drillholes totaling 681.2 metres were wedged off historical Cominco Ltd.'s (now "Teck
Resources Limited" or "Teck") drillhole 97-12, located 2.0 kilometres northwest of Teck's
Duncan
Mine Portal
(
Figure 1
). Partial assay results for one of the three drillholes, D22-02, are presented in
this news release. Assay results for drillholes D22-01, D22-03, and parts of D22-02 remain in
process.
Drillhole D22-01 extended drillhole 97-12 by
164.4 m
to a total depth of
1,000.6 m
. The drillhole
cored silicified Badshot Limestone in the west limb of the Duncan Anticline. At the Duncan Lake
Mine,
1,350 m
to the south of DDH D22-01, the west limb of the Duncan Anticline hosts the No.6
Zone, a broadly mineralized horizon with moderate lead and zinc endowment. Drillhole D22-01
successfully confirmed that the west limb of the Duncan Anticline exists north of historical drillhole
91-8, however visual observations suggests that it is weakly mineralized in this area. The northerly
continuation of both limbs of the permissive Badshot limestone on Rokmaster's Duncan Lake claims
continues to represent a strong Ag-Pb-Zn target over a strike length of 1.7 km.
Drillhole D22-03 tested the interpreted crest of the Duncan Anticline and encountered intensely
silicified Badshot Limestone that is locally mineralized with sphalerite and galena. Unexpectedly
strong, upward deflection of this drillhole, forced the trace of the drillhole to deviate above the
intended target, the lower Badshot Limestone – Mohican sediment contact.
Drillhole D22-02 was designed to test the continuity of the strong mineralization previously cored in
the No. 7 Zone by drillhole 97-12. Drillhole D22-02 cored a
34.75 m
wide zone of semi-massive
pyrite-sphalerite-galena mineralization. The silver assays in DDH D22-02 add further value to the
carbonate hosted Pb-Zn mineralized zones in this area of Duncan Lake, Table 1. Through decades
of exploration, the Duncan Camp has not been known to host significant silver concentrations paired
with the Pb-Zn mineralization. Silver grades averaged 1.7 g/t Ag from historic Cominco drilling north
of the Duncan Mine between 1989 and 1995. During the largest drill campaign by Teck Cominco in
1997, they did not assay for silver and the strength and significance of silver in the Duncan Lake
Mine area may not have been fully recognized.

Footnote 1. Reported widths of mineralization are drill hole intervals or core lengths recovered. Insufficient data exists to permit the calculation of a true width of the reported
mineralized interval.
John Mirko
, President and CEO of Rokmaster, stated: "The trend of increasing silver grades to the
north of the Duncan Lake mine suggested by Rokmaster (
News Release
Dec. 20, 2021
) is
supported by the enhanced silver values obtained from DDH D22-02. The data suggests that
carbonate hosted lead zinc occurrences in the Duncan Lake area offers shareholders the opportunity
to purse both a strong zinc-lead target as well as a promising silver enhanced target. Rokmaster's
Duncan Lake exploration programs are undertaken in an area with excellent access, near Teck's
smelter, with the right metallogenic 'address', and on a claim package large enough to reflect the
scale of this impressive mineralizing system."
Quality Assurance/Quality Control.
The press release documents the results of drill core samples
collected at Duncan Lake. All samples were shipped to MSA Labs in
Langley, British Columbia
. MSA
is an ISO 17025 (Testing and Calibration Laboratory) and an ISO 9001 (Quality Management
System) Certified Laboratory. Rock samples were crushed to 2 mm and a 250-gram sub sample
was pulverized with 85% of the sample passing 75 microns. The sub sample was analysed using a
combination of MSA Labs FAS111 for Au and IMS–230 (4 acid digestion) for silver, base metals and
other trace elements. FAS111 for gold is an ore grade fire assay of a 30 g pulp with an AAS finish
with a detection range between 0.01 and 100 ppm). IMS-230 utilizes four acid digestion and
provides trace level analytical data on silver, base metals and 44 other elements. Samples that
returned >1.0% Pb or >1.0% Zn from IMS-230 were automatically re-analyzed for Pb and Zn by
overlimits assay methods ICF-6Pb and ICF-6Zn, respectively. In addition to internal MSA lab
standards, Rokmaster submitted known standards into the sample stream.

About Rokmaster
Rokmaster controls a portfolio of three significant exploration and development projects all of which
are located in southern
British Columbia
in regions of excellent infrastructure. The three projects
include:
1.
Revel Ridge.
Rokmaster is currently conducting an underground drill program at the Revel
Ridge project located in southeastern
British Columbia
35 km's N of the
City of Revelstoke
. Revel
Ridge is a high-grade gold and polymetallic orogenic sulphide deposit which has been the subject of
a PEA Technical Report dated
December 8, 2020
and a *Technical Report of an Updated Mineral
Resource Estimate on the Revel Ridge Property, dated
January 17, 2022
.
2.
Big Copper.
Rokmaster controls the Big Copper property in the
Creston
area of
Southern
British Columbia
. Big Copper is a high-grade copper-silver occurrence hosted in mid-Proterozoic
rocks. Copper-silver mineralization has been traced for 4 km along strike and is exposed in a series
of adits and trenches over approximately 400 -
500 m
of vertical relief. Big Copper likely belongs to
a class of stratabound replacement copper-silver deposits hosted within mid – Proterozoic quartzitic
sediments. The style and stratigraphic setting of mineralization at Big Copper may be analogous to
similar stratabound silver-copper deposits in
NW Montana
e.g., the Troy mine (64 million tonnes of
0.74% Cu and 54 g/t Ag (Western Mining History, 2020) or
Hecla's
Montanore Mine, 112 million
tonnes at 51.2 g/t Ag and 0.7% Cu (
Hecla
, 2020 Annual Report, Pg. 119.

).*

3.
Duncan Lake Zinc.
Duncan Zinc is a carbonate hosted silver-lead-zinc deposit located near
Duncan Lake in southern
British Columbia
. The deposit is hosted within a Cambrian age Badshot
Limestone which also hosts silver-lead-zinc mineralization at Teck's past producing Pend Oreille
mine as well as past producers including the Blue Bell Mine, Reeves MacDonald, Jersey Emerald
and HB mines. Mineralization at Duncan Lake forms in the crest and limbs of the regional scale
Duncan Lake anticline, where strong lead-zinc +/- silver mineralization has been traced by surface
and underground drilling for approximately
2,500 m
. At Duncan Lake, Rokmaster will be targeting >
30 Mt of >10% Pb+Zn+Ag. Historical background and a geological synthesis of the Duncan Lake
deposit is provided in a NI 43-101 report by
Lane, B., 2018: Technical Report on the Duncan Lake
Project.
