Rokmaster Announces Initial Assay Results
from its 2021/2022 Metallurgical Drilling
Program at Revel Ridge.
VANCOUVER, BC
,
Jan. 27, 2022
/CNW/ - Rokmaster Resources Corp. (TSXV: RKR) (OTCQB:
RKMSF) (FSE: 1RR1) ("Rokmaster" or the "Company") is pleased to announce the results of the
first four drillholes of the ongoing
3,000 m
metallurgical drilling program at the Revel Ridge Project
("Revel Ridge"), located 35 km northeast of
Revelstoke, B.C.
Revel Ridge hosts a gold rich,
polymetallic orogenic gold deposit, and is one of the largest undeveloped deposits of this type in the
Western Cordillera.
Rationale for 2021 and 2022 Metallurgical Drill Program.
The ongoing metallurgical drill program utilizes HQ
1
core. Rokmaster's previous drilling in the 2020
and 2021 underground and surface drilling programs used industry standard NQ core. The
metallurgical sampling program is designed to obtain large volumes of mineralized drill core for
metallurgical testing. The larger diameter HQ core produces 62% more volume of material per unit
length than NQ
2
core. In the current program, a second drillhole is wedged from the pilot hole,
providing Rokmaster with a second mineralized rock volume, with significantly less drilling.
Historically, the majority of the metallurgical studies initiated at Revel Ridge acquired metallurgical
bulk samples from the
830 m
underground drift. The samples were representative of a few hundreds
of metres of strike length of the Revel Ridge Main Zone, a gold rich polymetallic orogenic gold
deposit, but only at the
830 m
elevation level. Rokmaster's 2020 and 2021 exploration programs
have demonstrated that:
The mineralized deformation zone that hosts the Revel Ridge deposit is very large. It has
excellent continuity over 1,200 vertical m and is known to persist over strike lengths exceeding
3,500 m
.
The nature of gold mineralization within this large mineralized system may have significant
variations in mineralogy, including the potential evolution to a mineralized system with greater
amounts of macroscale, visible gold (Rokmaster News Release,
June 7, 2021
).

Rokmaster's current metallurgical program entails drilling approximately
3,000 m
of HQ core, in 14
drillholes. These drillholes will obtain metallurgical samples from the Yellowjacket, Main, Hanging
Wall and Footwall mineralized zones. The samples will be used to examine variations in metallurgical
characteristics of higher elevation levels (up to
890 m
), as well as lower elevations (down to
390 m
)
within the Revel Ridge mineralized zones. The HQ drillholes in the current program will also obtain
samples from over
700 m
of strike length of this impressive mineralized system (Figure 1 Rokmaster
Metallurgical Drill Hole – Longitudinal).
Analytical Results Metallurgical Drillholes
. In addition to conducting metallurgical studies on HQ
core samples, HQ drillholes are used to obtain confirmation assays from mineralized zones which
may have had limited testing. The results from the first four drillholes in the metallurgical drill
program are presented on Table 1. The initial results are significant as:
All drillholes hit significant mineralized intervals of the Main ("RRMZ"), Yellowjacket ("RRYZ")
and Footwall ("RRFZ") zones.
All samples significantly exceed the cut-off grades and widths used for inclusion in the revised
and updated mineral resource estimate "MRE" (Rokmaster News Release,
January 17, 2022
).
Two of the metallurgical drillholes, RR21-80 and RR21-81 contain macroscale gold in sheeted
quartz-iron carbonate veins identified in the Footwall Mineralized Zone.
The up-dip extension of the Mineralized Zone in the area of the 830 drift has had very limited
drilling. The strongly positive results of DDH RR21-82, drilled
60 m
above the 830 adit, suggests
significant potential exists in this large, and largely untested, target area.

John Mirko
, President & CEO of Rokmaster stated, "Our current metallurgical drilling program is the
first concerted effort in the long history of the Revel Ridge deposits to gain a systematic
understanding of the metallurgical characteristics over large areas. Over the past four decades,
metallurgical methods and techniques have experienced quantum steps in their ability to cost
effectively deal with gold liberation in high sulphide auriferous gold deposits. Over the past 12
months, Rokmaster's metallurgical team has already raised the benchmark in the process metallurgy
of the Revel Ridge ores. We fully anticipate that the current metallurgical drilling program, and the
results of these leading-edge metallurgical studies will conclusively demonstrate that cost effective
metallurgical processes are attainable at Revel Ridge. Positive results to those studies will provide
the final key to unlock the incredible mineral endowment of the Revel Ridge deposits."
Quality Assurance/Quality Control.
Dr.
Jim Oliver
, P. Geo. supervised all aspects of the drilling
and sampling undertaken in the 2021 underground and surface diamond drill program. All samples
have been collected from ½ HQ core, sawn with a diamond saw with the sample intervals marked
by technical personnel. A full QAQC program using blanks, standards and duplicates was utilized to
monitor analytical accuracy and precision. QAQC samples are submitted approximately at every
20
th
sample, or a minimum of 5% of the total sample stream is be represented by QAQC samples.
Two standards are used and are designed to provide information on (a.) higher grade characteristics
of mineralized intervals and (b.) on mid-grade samples. A limestone blank is inserted after any
sample which has macroscale characteristics of higher-grade mineralization. Duplicate samples are
repeat analysis of pulp samples from the designated primary sample. The samples were sealed on
site and 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. Drill
core samples were crushed to 2 mm and a 500-gram sub sample was pulverized with 85% of the
sample passing 75 microns. The sub-sample was analysed using a combination of MSA Labs
FAS211 for Au and ICP–240 (4 acid digestion) for silver, base metals and other trace elements.
FAS211 for gold is an ore grade fire assay of a 50 g pulp with an AAS finish with a detection range
between 0.01 and 100 ppm). ICP-240 utilizes four acid digestion and provides ore grade analytical
data on silver, base metals and 26 other elements.

About Rokmaster
Rokmaster controls a portfolio of three significant exploration and development projects all of which
are 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 Preliminary Economic Assessment Technical Report dated
December 8, 2020
and
an updated MRE with an effective date of
November 15, 2021
, both published on Sedar.
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 to
500 m
of vertical relief. Big Copper likely
belongs to a class of stratabound replacement copper-silver deposits hosted within mid –
Proterozoic quartzitic sedimentary rocks. 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.

.
Duncan Zinc.
Duncan is a carbonate hosted silver-lead-zinc deposit located near Duncan Lake
in southern
British Columbia
. The Duncan Deposit is hosted within a Cambrian age Badshot
Limestone which also hosts Ag-Pb-Zn mineralization at Teck's currently producing Pend
D'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
2500 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.
