VANCOUVER, BC, Dec. 5, 2022
/CNW/ - Rokmaster Resources Corp. (TSXV: RKR) (OTCQB: RKMSF)
(FSE: 1RR1) ("Rokmaster" or "the Company") reports the final drill
core assay results from the Summer 2022 drill program at the Revel
Ridge Project ("Revel Ridge" or "the Project").
The primary objective of the Summer 2022 drill program was to
test and expand the mineralized zones external to the boundaries
defined by the 2021 Mineral Resource Estimate ("MRE"). The bulk of
the total 4,803 metres drilled were committed to expanding the
Revel Ridge Main Zone ("RRMZ") and Revel Ridge Yellowjacket Zone
("RRYZ") to the northwest at deeper levels. This drilling targeted
mineralized zones, down-dip of selected 2021 drillholes completed
to the northwest of the 832 Portal, adjacent to the 2021 MRE
volumes at depth.
Substantial extensions of the RRMZ were achieved 900 m to the southeast and 3,075 m northwest by shallow drillholes which
intersected the RRMZ mineralized structural zone, further
increasing the potential on the Project which enjoys an ideal
development location (Figure 1- Plan Map).
Drillholes RR22-103 to RR22-105 were collared 150 m to the northwest of drillholes RR22-99 to
RR22-102a. These three drillholes targeted a favourable
limestone-quartzite contact which hosts strong RRMZ massive
sulphide mineralization in drillhole RR22-102a (8.84 g/t
AuEq3 over 4.20 m; RKR
news release dated Sept 26, 2022) and
RR22-101 (6.73 g/t AuEq over 2.00 m;
RKR news release dated Nov. 28,
2022). The RRMZ was intersected in each drillhole, with
RR22-104 and RR22-105 encountering the RRMZ at this optimal contact
as it moderately plunges to the northwest (Figure 2 – Long Section).

Footnote 1.
Reported widths of mineralization are drill hole intervals or core
lengths recovered. Insufficient data exists to permit the
calculation of true width of the reported mineralized
intervals.
Footnote 2. Mineralized Zone
abbreviations: RRMZ: Revel Ridge Main Zone, RRFZ: Revel Ridge
Footwall Zone.
Footnote 3. AuEq calculations use:
Metal prices of Au US$1,625/oz, Ag US$22/oz, Pb US$0.95/lb, Zn
US$1.20/lb; RRMZ process recoveries of Au 92%, Ag 88%, Pb 80%, Zn
72%; RRMZ AuEq = Au g/t + (Ag g/t x 0.012) + (Pb% x 0.347) + (Zn% x
0.353); RRYZ process recoveries of Au 91%, Ag 80%, Pb 74%, Zn 75%;
RRYZ AuEq = Au g/t + (Ag g/t x 0.011) + (Pb% x 0.325) + (Zn% x
0.372). RRFZ uses identical process recoveries as the
RRMZ.

Drillholes RR22-107 to RR22-109 targeted the RRMZ below
drillhole RR22-102a to test and expand the 2021 MRE to the
northwest at deeper levels (Figure 2 – Long
Section). Typical RRMZ structural and alteration features
were successfully intersected in all three drillholes, with
drillholes RR22-107 and RR22-109 hosting banded massive sulphide
mineralization.

Drillhole RR22-106 was collared 3,075
m to the northwest of the drillholes RR22-103 to RR22-105
where a strong soil geochemistry anomaly and coincident geological
mapping suggests the continuation of the RRMZ (Figure 1 – Plan
Map). This target was tested in 2021 by drillholes RR21-67 and
RR21-68, with the former returning anomalous assays including 0.70
g/t Au over 1.90 m within a zone of
strong alteration proximal to a limestone-phyllite contact.
Notably, this contact is precisely where the RRMZ is expected to
occur when extrapolating the structural plane from the 2021
northwestern drillholes, all of which intersected the RRMZ ductile
deformation structure and related alteration.
During this program, RR22-106 was completed as a shallow
drillhole 250 m to the northwest of
RR21-67 targeting a continuous and linear soil geochemical anomaly.
In DDH RR22-106 a similar limestone-phyllite contact was
encountered, with the footwall graphitic phyllite hosting an
anomalous assay of 0.26 g/t Au over 3.00
m. Due to topography, this intersection of the RRMZ is at an
elevation approximately 770 m
vertically higher than the 830 level underground workings, which
potentially affects the strength of the sulphide
mineralization.
Drillhole RR22-106 represents a significant strike extension to
the RRMZ, with the distance to the Zinc Creek drillholes to the
southeast (see news release dated September
26, 2022) totalling 5,720 m.
This drillhole, in concert with the 2021 drilling, opens a
significant area of the RRMZ to explore, where deeper drilling may
encounter more robust sulphide mineralization (Figure 3 – Long
Section Detailed).
John Mirko, President and CEO,
comments "The drill programs completed at the Revel Ridge
Project in 2022 pushed the limit of the RRMZ without reaching the
end. This remarkable and unique orogenic gold-polymetallic system
is persistent over 5.7 kilometres and still remains open along
strike and at depth. It should be emphasized that the current MRE
is built using an array of drillholes over a strike length of
approximately 1.8 kilometres, or only 32 percent of the currently
known strike length of the RRMZ.
The drilling of the northwestern extension, highlighted by
drillholes RR22-102a, -101, and -104, exemplify that with broad
drillhole spacing, new areas of strong RRMZ mineralization can be
discovered. More drilling to find amenable lithological
hosts, contacts, and permissive structural sites that strengthen
the RRMZ is required to realize the true potential.
All drillhole data has been delivered to the engineering and
resource estimation firms who are moving forward on the update to
the PEA and updated resource estimate. The updated PEA will be
incorporating the 2021 resource update (see below) in addition to
the recent metallurgical break-through that demonstrably improves
gold recoveries. Both the updated PEA and resource estimate are
expected in early 2023."
Quality Assurance/Quality Control. Dr. Jim Oliver, P. Geo. supervised all aspects of
the drilling and sampling undertaken in the 2021 and 2022
underground and surface diamond drill programs. All drill core
assay 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. QAQC samples are submitted approximately at every 20th
sample, or a minimum of 5% of the total sample stream. Appropriate
standards are used to provide quality control information on high
grade and medium to low grade samples. A limestone blank is
inserted after select samples that have macroscale characteristics
of higher-grade mineralization. Duplicate samples are repeat
analysis of designated primary sample pulps. The samples were
sealed on site and shipped to MSALABS in Langley, British Columbia. MSALABS 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 MSALABS 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.
