Rokmaster Resources Corp. (TSX-V: RKR) (OTCQB: RKMSF) (FSE: 1RR1) is pleased to present assay results of the first seven diamond drill holes, RR21-41 to RR21-47, from its inaugural surface drill program at the Revel Ridge polymetallic gold-silver Project. The results of DDH’s RR21-41 to RR21-47 document the significant contribution that the expanded silver rich, carbonate hosted Yellowjacket Zone will provide to the net resource at Revel Ridge. The data conclusively demonstrates that significant volumes of both the silver enriched RRYZ and the gold enriched Main Zone mineralization are continuing to the northwest of the 2020 resource area (Rokmaster news release, December 8, 2020).
Revel Ridge Surface Drill Highlights:
Significant expansion of known RRYZ silver-zinc mineralization is documented by:
Currently, 21 surface NQ diamond drillholes, totalling approximately 4,400 m of drilling have been completed on the northwestern strike extensions of both the silver rich RRYZ and the gold rich RRMZ. The results from the first seven of these drillholes, RR21-41 to RR21-47 are documented in this press release. The plan map illustrates the locations of all of the drillholes collared to date in the 2021 surface drill program, and is presented on the digital link Figure 1. Plan Map 2021 Surface Drilling. The longitudinal section showing 2020-2021 drill hole locations is presented on the digital link Figure 2. RRMZ Longitudinal Section. These drillholes tested segments of the RRMZ and RRYZ up to 200 m to the northwest of the 830 m portal and up to 200 m distal to the envelope which defines the 2020 measured and indicated gold-silver resource. The results of these drillholes are compiled on Table 1. Currently, Rokmaster’s surface drill rig is positioned 1,500 m to the northwest of the 830 m Level Portal and continues to intersect the RRMZ. The significance of these results is summarized below:
John Mirko, President and CEO of Rokmaster stated:
“Rokmaster’s 2021 surface drill program has already achieved remarkable success and is achieving both of our principal goals. The first goal of this program was the expansion of the silver-zinc rich, carbonate hosted Yellowjacket mineralization in the near mine environment. The silver grades within the RRYZ are second to none within carbonate hosted Ag-Pb-Zn deposits of British Columbia’s Kootenay Arc. The strength of silver mineralization, in DDH’s RR21-41 to RR21-47, as well as the persistent orogenic gold mineralization within the RRMZ, are a testament to the unique metallogeny of the Revel Ridge camp.
Rokmaster is currently pursuing the second goal of expanding the gold rich RRMZ along strike, by collaring a series of widely spaced drillholes along the laterally persistent deformation zone that hosts the RRMZ. These drillholes are targeting mineralized segments of the RRMZ several km distance from the current resource area. Every successful drillhole, in this greenfields exploration environment, further expands the larger scale potential of the Revel Ridge camp, and in these drillholes we are effectively looking for a “new mine.”
The positive results of the 2020 – 2021 underground and surface drill programs continues to reinforce the concept that Revel Ridge is one of the premier undeveloped gold-silver deposits within the western cordillera.”

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 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 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 2021 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 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.
In addition, the Company has granted 425,000 incentive stock options to consultants of the Company under the Company’s stock option plan. The options are exercisable for a period of three years at an exercise price of $0.50 per common share.
