VANCOUVER, BC,
Feb. 11, 2021
/CNW/ - Rokmaster Resources Corp. (TSXV: RKR) (OTCQB:
RKMSF) (FSE: 1RR1) ("Rokmaster" or the "Company") is pleased to present further assay results
from diamond drill holes RR20-01 – RR20-11 from its ongoing drill program at the Revel Ridge
polymetallic gold-silver Project ("Revel Ridge" or the "Project") which demonstrate the remarkable
continuity of structurally controlled gold mineralization in the Revel Ridge Main Zone ("RRMZ") and
the parallel Footwall Zone ("RRFZ"), and significant silver grades in the Yellowjacket Zone ("RRYZ").
Rokmaster has currently completed 27 diamond drill holes in the 2020 and 2021 programs, totalling
9,304 m
of NQ sized drill core. The plan map illustrating the collar locations of all of the drillholes
collared to date in the 2020 and 2021 programs is presented on the digital link

and the location of all drillholes completed in 2020 and 2021
are illustrated on the block model presented on the digital link

Out of the 11
drillholes (RR20-01 to RR20-11) for which all assays have been received to date, 8 of
the 11 boreholes intersected gold equivalent grades and widths which would be included in an
inferred resource calculation using the parameters described in the
December 2020
Preliminary
Economic Assessment ("PEA") study (Rokmaster news release dated
December 8, 2020
). Assay
results of one of these drillholes, DDH RR20-11, has been previously released (Rokmaster news
release dated
December 11, 2020
).

.
The 2020 and ongoing 2021 drill programs have intersected the RRMZ mineralization from an
elevation of
936 m
up to
341 m
. Using this and historical data, Rokmaster has shown that the
RRMZ mineralization demonstrates remarkable continuity over a vertical distance of
595 m
and
has successfully been drilled along strike for
1,025 m
. Within the approximate 55-degree
dipping plane of mineralization, significant gold mineralization has been demonstrated over
down-dip distances of
745 m
.
2
.
Within the RRMZ, the mineralogic, alteration and structural signatures of well-mineralized rock
at shallowest elevation datums are virtually identical to the mineralogic, alteration and structural
vectors at deepest elevation datums. Mineralization within the RRMZ remains open in virtually all
strike and dip directions. Currently, successful RRMZ intersections have been obtained
250 m
external to the inferred resource volumes documented in the
December 8, 2020
PEA.

.
Drillholes RR20-01, 02 and 08 all had variable gold mineralization but those results fell below
the threshold used for inclusion in this news release. The threshold used for inclusion in this
news release is approximately 2.5 g/t AuEq over greater than
2.0 m
.
4
.
In addition to the RRMZ, significant results were intersected in the silver-rich RRYZ and the gold
bearing RRFZ.
The results from drillholes RR20-03, 04, 05, 06, 07, 09 and 10 are presented in Table 1.
John Mirko
, President and CEO and Rokmaster, commented: "Successfully targeting the RRMZ
mineralization over long step-out distances both along strike and up and down dip is a clear
testament to the remarkable continuity of the deformation zone that hosts the gold and poly metallic
mineralization within the RRMZ. The observation that significant gold mineralization has been
repeatedly cut, on an estimated 50 –
100 m
centres, with an approximate 75% success rate, is an
outstanding ratio for any gold deposit. Drilling has also shown that while the RRMZ mineralization is
highly planar, the higher-grade silver mineralization associated with the Yellowjacket Zone ("RRYJ"),
is likely located in a deformed anticlinal fold. This structure may thicken the silver enriched RRYJ
sulphides in the keel and stack the same sulphide horizon, at least twice, along its limbs. Both the
RRMZ and RRYJ remain open in several directions. With the continued success of our ongoing
drilling, we anticipate a revised resource calculation for the Project in the coming months."

Reported widths of mineralization are drill hole intervals or core length recovered. Insufficient data
exists to permit the calculation of true widths of the reported mineralized intervals.
*The metal values used in the gold equivalent calculations of
US$1,561
/oz Au,
US$20.55
/oz silver,
US$0.91
/lb lead and
US$1.07
/lb zinc, are based on the consensus average long-term price
forecasts published by
a major commercial bank at the end of October, 2020, as per the Technical
Report, with an effective date of
December 8, 2020
by Micon International Limited, entitled: An
Updated Preliminary Economic Assessment Of The Revel Ridge Project,
Revelstoke, BC
,
Canada
,
for Rokmaster Resources Corp
. The formula used to calculate gold equivalence for the RRMZ and
RRFZ is:
AuEq = Au g/t + (Ag g/t x 0.013) + (Pb% x 0.4) + (Zn% x 0.47). The formula used to
calculate silver equivalence for the RRYJ is: AgEq = Ag g/t + (Au g/t x 75.96) + (Pb% x 30.3) +
(Zn% x 35.6).
Quality Assurance/Quality Control.
Dr.
Jim Oliver
, P. Geo. supervised all aspects of the drilling
and sampling undertaken in the 2020 underground diamond drill program. All samples have been
collected from ½ NQ 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. 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. Core 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 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 30 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 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
.
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 3 km along strike and is exposed in a
series of adits and trenches over approximately 250-
300 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
website link).
3
.
Duncan Zinc.
Duncan 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 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.
