ROKMASTER IDENTIFIES NEW GOLD-SILVER, ZINC-SILVER STRIKE EXTENSIONS AND TRENDS
Rokmaster Resources Corp. hasoutlined recent progress at its Revel Ridge project, including: (1) characterizing the southeastern gold-rich extension of the Revel Ridge Main zone (RRMZ); (2) outlining a second mineralized trend potentially characterized by the carbonate-hosted (carbonate replacement deposit) style silver-lead-zinc rich Revel Ridge Yellowjacket zone (RRYZ); and (3) providing timelines on the 2021 resource update. Underground drilling is currently under way, having resumed Nov. 10, 2021.
(1)Southeast extensions to RRMZ
Soil geochemical surveys have outlined strong arsenic-lead-zinc soil and talus fines anomalies striking along the trend of the RRMZ to the southeast. Anomalous rock and soil samples extend for an additional 1,900 metres past historic surface diamond drilling and greater than 2,000 metres external to the RR 2020 National Instrument 43-101 gold resource (Putrich et al., 2020, published on SEDAR). The area is characterized not only by the persistent presence of the deformation zone, which hosts gold at Revel Ridge, but also the re-emergence of thick, permissive limestone rock units proximal to the deformation zone. Representative historic rock samples from the interpreted RRMZ in the southeast target area include:
Zinc Creek:7.2 grams per tonne gold, 121 grams per tonne silver, 6.55 per cent lead and 12.99 per cent zinc; Y Creek:6.47 grams per tonne gold and 36 grams per tonne silver.
(2) A&E South zone -- silver-lead-zinc (RRYZ) mineralized trend
The A&E South zone is defined by a series of rock and soil geochemical samples that characterize a near-continuous zone of strongly enhanced arsenic-lead-zinc soil geochemistry over distances exceeding 1,000 metres. Massive sulphide boulders and float samples in this area contained up to 473 grams per tonne silver, 13.39 per cent lead and 37.14 per cent zinc. Massive sulphide boulders and enhanced soil talus fine geochemistry is occurring within a few tens of metres of the contact of the Badshot limestone with fine-grained black clastic sediments of the Index formation. Arsenic and gold values in this area are modest and the geochemical signatures and mineralogy of the A&E South zone has more in common with the silver-rich RRYZ than the gold-rich RRMZ. This target has not been drill tested and remains open to the southeast.
(3)Timeline on Revel Ridge resource update
The company is pleased to report that all assays from the 39 NQ surface drill holes, completed during the June to October period, have been received and compilation continues with no quality assurance/quality control issues identified. The complete database, both surface and underground drill holes, are being integrated into a revised NI 43-101-compliant resource update developed by P&E Mining Consultants. Preliminary review of these data will be undertaken Nov. 12,2021, with public disclosure of those results to follow shortly after.
John Mirko, president and chief executive officer of Rokmaster, stated:"Rokmaster's surface exploration programs continue to demonstrate the untapped potential of large portions of the Revel Ridge property, including:
"Surface drilling has doubled the strike length of known mineralization of the RRMZ to the northwest."Soil geochemical and talus fine surveys have added 2,000 metres of strike potential to the RRMZ to the southeast. Historic work, including drilling, is exceptionally limited, providing strong opportunities for drill testing Tier 1 gold targets."The A&E South zone has all the geochemical, stratigraphic and structural characteristics of silver-rich carbonate replacement system (CRD) in an area of no drill testing.
"The number of gold-silver-lead-zinc occurrences within the Revel Ridge area demonstrates the strength of the mineralizing system associated with these deposits. Our goal is to continue to advance the RRMZ and RRYZ, simultaneously moving adjacent and related gold-silver and silver-zinc targets forward."
Quality assurance/quality control
A full QA/QC program using blanks, standards and duplicates was utilized to monitor analytical accuracy and precision. The samples were sealed on site and shipped to MSALABS in Langley, B.C. MSALABSis an ISO 17025 (Testing and Calibration Laboratory) and an ISO 9001 (Quality Management System) certified laboratory. Rock samples were crushed to two millimetres and a 500-gram subsample was pulverized,with 85 per cent of the sample passing 75 microns. The subsample was analyzed using a combination of MSALABS FAS211 for gold and ICP-240 (four-acid digestion) for silver, base metals and other trace elements. FAS211 for gold is an ore-grade fire assay of a 50-gram pulp with an AAS finish with a detection range between 0.01 part per million and 100 parts per million). ICP-240 utilizes four-acid digestion and provides ore-grade analytical data on silver, base metals and 26 other elements. All soil samples were dried, screened and analyzed for base metals and arsenic using a hand-held Niton XRL2 instrument.

About Rokmaster Resources Corp.
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:
Revel Ridge: Rokmaster is currently conducting an underground drill program at the Revel Ridge project located in southeastern British Columbia 35 kilometres north of the city of Revelstoke. Revel Ridge is host to a high-grade gold and polymetallic orogenic sulphide deposit, which has been the subject of a PEA (preliminary economic assessment) technical report dated Dec. 8, 2020.Big Copper: Rokmaster controls the Big Copper property in the Kimberley 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 three kilometres along strike and is exposed in a series of adits and trenches over approximately 250 metres to 300 metres 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 northwestern Montana; for example, the Troy mine (64 million tonnes of 0.74 per cent copper and 54 grams per tonne silver (Western Mining History, 2020) or Hecla's Montanore mine (112 million tonnes at 51.2 grams per tonne silver and 0.7 per cent copper). Duncan Lake:Duncan Lake is a carbonate-hosted zinc-lead-silver deposit located near Duncan Lake in Southern British Columbia. The deposit is hosted within a Cambrian-age Badshot limestone, which also hosts the zinc-lead-silver mineralization at Teck's currently producing Pend D'Oreille mine as well as past producers, including the Blue Bell mine, the Reeves MacDonald mine, and the Jersey-Emerald and HB mines. Mineralization at Duncan Lake forms in the crest and limbs of the regional-scale Duncan Lake anticline, where strong zinc-lead-plus-or-minus-silver mineralization has been traced by surface and underground drilling for approximately 2,500 metres. At Duncan Lake, Rokmaster will be targeting greater than 30 million tonnes of greater than 10 per cent lead plus zinc plus silver. Historical background and a geological synthesis of the Duncan Lake deposit is provided in an NI 43-101 report by B. Lane,018: "Technical Report on the Duncan Lake Project."
