Rokmaster Drills 34.75m Zinc-Lead Zone Hosting Significant Silver at Duncan Lake Zinc Project.

VANCOUVER, BC, May 17, 2022 /CNW/ – Rokmaster Resources Corp. (TSXV: RKR) (OTCQB: RKMSF) (FSE: 1RR1) (“rokmaster” or the “company“) is pleased to announce initial assay results from diamond drilling at the Duncan Lake Zinc Project. An initial drilling campaign has been completed early April 2022 with the purpose of confirming historical drill intersections and providing valuable geological information.

Duncan Lake 2022 Drill Program (CNW Group/Rokmaster Resources Corp.)

Three drill holes totaling 681.2 meters were drilled prior to Cominco Ltd. historic drill hole 97-12. (now “Teck Resources Limited” or “Teck”), located 2.0 kilometers northwest of Tecks Duncan Mine Portal (Illustration 1). Partial assay results for one of three drill holes, D22-02, are presented in this news release. Assay results for holes D22-01, D22-03 and portions of D22-02 are pending.

Hole D22-01 extended hole 97-12 at 164.4m to a depth of 1,000.6m. The drill hole cored the silicified Badshot Limestone in the western limb of the Duncan Anticline. At the Duncan Lake Mine, 1,350 m south of DDH D22-01, the western limb of the Duncan anticline hosts Zone No. 6, a broadly mineralized horizon with moderate lead and zinc values. Drill hole D22-01 successfully confirmed that the western limb of the Duncan anticline exists north of historical drill hole 91-8, however visual observations indicate that the area is weakly mineralized. The northern continuation of both arms of the permeable 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.

Drill hole D22-03 tested the interpreted crest of the Duncan anticline and encountered heavily silicified Badshot limestone locally mineralized with sphalerite and galena. An unexpectedly strong upward deflection of this drill hole forced the trace of the drill hole to deviate over the intended target, the lower Badshot limestone-Mohican sediment contact.

Hole D22-02 was designed to test the continuity of strong mineralization previously drilled in the #7 zone by hole 97-12. Drill hole D22-02 cored a 34.75m broad zone of semi-massive pyrite-sphalerite-galena mineralization. Silver assays in DDH D22-02 add further value to the carbonate-hosted Pb-Zn zones of mineralization in this Duncan Lake area, Table 1. Due to decades of exploration, the Duncan Camp was not known to contain significant silver concentrations coupled with the Pb-Zn mineralization. Silver grades from historic Cominco drilling north of the Duncan Mine between 1989 and 1995 averaged 1.7 g/t Ag. During Teck Cominco’s largest drilling campaign in 1997, they did not test for silver or the strength and importance of silver in Duncan Lake The mine area may not have been fully recognized.

Footnote 1. Reported widths of mineralization are drill hole intervals or recovered core lengths. There is insufficient data to calculate a true width of the reported mineralized interval.

John MirkoPresident and CEO of Rokmaster, stated: “Rokmaster’s (press release December 20, 2021) is supported by the improved silver values ​​from DDH D22-02. The data indicates that carbonate-bearing lead-zinc occurrences in the Duncan Lake area offer shareholders the opportunity to pursue both a strong zinc-lead target and a prospective silver-enriched target. Rokmaster’s Duncan Lake exploration programs are being conducted in an area of ​​excellent access near Teck’s smelter with the correct metallogenic “address” and on a claim package large enough to reflect the size of this impressive mineralized system.

Quality Assurance / Quality Control. The news 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 ISO 9001 (quality management system) certified laboratory. Rock samples were crushed to 2mm and a 250 gram sub-sample was pulverized with 85% of the sample passing 75 microns. The subsample was analyzed using a combination of MSA Labs FAS111 for Au and IMS-230 (4 acid digest) for silver, base metals and other trace elements. FAS111 for gold is a 30g pulp fire assay with an AAS finish with a detection range between 0.01 and 100ppm). IMS-230 uses four-acid digestion and provides analytical trace data on silver, base metals and 44 other elements. Samples that returned >1.0% Pb or >1.0% Zn from the IMS-230 were automatically reanalyzed for Pb and Zn using the ICF-6Pb and ICF-6Zn exceedance assay methods, respectively. In addition to the internal MSA laboratory standards, Rokmaster submitted known standards into the sample stream.

About Rokmaster

Rokmaster controls a portfolio of three significant exploration and development projects, all located in the South British Columbia in regions with excellent infrastructure. The three projects include:

1. Revel Ridge. Rokmaster is currently conducting an underground drilling program at the Revel Ridge project to the southeast British Columbia 35 km north of the City of Revelstoke. Revel Ridge is a high-grade gold and polymetallic orogenic sulphide deposit that has been the subject of a dated PEA technical report 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 United States Creston area of Southern British Columbia. Big Copper is a high-grade copper-silver occurrence in Middle Proterozoic rocks. Copper-silver mineralization has been traced for 4 km along strike and is contained in a series of adits and trenches over approximately 400 – 500m of the vertical relief. Big Copper is likely to belong to a class of stratabound replacement copper-silver deposits hosted in Middle Proterozoic quartzite sediments. The style and stratigraphic arrangement of the mineralization at Big Copper may be analogous to similar stratabound silver-copper deposits in NW Montana B. the Troy mine (64 million tons at 0.74% Cu and 54 g/t Ag (Western Mining History, 2020) or Heclas Montanore Mine, 112 million tonnes grading 51.2 g/t Ag and 0.7% Cu (HeklaAnnual Report 2020, p. 119.*2

3. Duncan Lake Zinc. Duncan Zinc is a carbonate hosted silver-lead-zinc deposit near Duncan Lake to the south British Columbia. The deposit is hosted in a Cambrian Badshot Limestone that also hosts silver-lead-zinc mineralization at Teck’s past producing Pend Oreille mine and past producers including the Blue Bell Mine, Reeves MacDonald, Jersey Emerald and HB mines. Mineralization at Duncan Lake occurs in the ridge and extensions of the Duncan Lake regional anticline, where strong lead-zinc+/-silver mineralization has been traced by surface and underground drilling for approximately 2,500m. At Duncan Lake, Rokmaster is targeting >30 Mt at >10% Pb+Zn+Ag. Historical background and a geological synthesis of the Duncan Lake deposit are provided in a NI 43-101 compliant report from Lane, B., 2018: Technical Report on the Duncan Lake Project.
