The presence of coarse particulate gold within the RRMZ could significantly enhance the mineral economics of this already superb deposit.вЂќ These data begin to challenge historical perceptions regarding gold metallurgical characteristics at Revel Ridge. RokmasterвЂ™s technical team is further reviewing 20 drillholes for similar particulate gold geochemical signatures.

At deeper portions of the RRMZ, the gold вЂњbudgetвЂќ may be shifting from gold associated with sulphide phases to free milling particulate gold. Most recently, particulate gold identified in DDHвЂ™s RR21-28, RR21-36, and RR21-40 convincingly demonstrate that Main Zone mineralization, at deeper depths in the RRMZ system, has the ability to produce relatively coarse macroscale gold. Very significantly, the 2020 metallurgical results were all obtained from bulk samples collected from the 830 m drift. The remainder of gold is intimately associated with sulphide phases and is recovered by processing methods including Pressure Oxidation (POX). The metallurgical studies undertaken by Rokmaster have definitively demonstrated that approximately 15% of gold mineralization within the deposit is present as free milling вЂњoreвЂќ and could be recovered by using advanced grinding and liberation methods. Two events have unfolded in the past year which challenge this perception. John Mirko, President and CEO of Rokmaster commented, вЂњFor decades, the Revel Ridge Main Zone mineralization has been perceived as an exceptionally significant gold deposit, albeit one with problematic metallurgical characteristics. Insufficient data exists to permit the calculation of true widths of the reported mineralized intervals. Reported widths of mineralization are drill hole intervals or core length recovered. Au g/t (-106 um Fraction) is all gold grains in the sample which is less than or equal to 106 microns and is analyzed by instrument finish (FAS-211). Au g/t (+106 um Fraction) is the result of a fire assay gravimetric finish (FAS вЂ“ 415) of all grains greater than or equal to 106 microns.

Au g/t (1.0 kg Metallic Screen) is a 1.0 kg sample which contains the calculated weighted average gold content of both the oversize (+) and undersize (-) samples or the total metallically screened gold in the sample. Au g/t (30 g FA вЂ“ AAS) is the original fire assay of the original drill hole sample collected prior to metallic screening. Screened Metallic Fire Assay Results versus Fire Assay Results. Gold in this resident site is not locked into a sulphide phase and has a high probability of being recovered by standard, lower cost metallurgical processes, including gravity. Qualitative, textural and mineralogical characteristics suggests that veins containing coarse gold grains may post-date the formation of auriferous-arsenical high sulphide orogenic veins. In all three drillholes, particulate gold is associated with quartz and or quartz+/-carbonate foliation parallel veins sometimes containing other base metal phases and occasionally arsenopyrite.Increased analytical variability may be one of the hallmark characteristics of particulate gold assays, per Table 1. Of the six samples submitted for metallic screen assay analysis, three samples had significantly higher gold contents than the initial analysis, one sample was approximately equivalent, and two samples had reduced gold assay values.The spatial relationships between these drillholes are illustrated on Figure 1. Particulate gold was intersected approximately 380 to 490 m vertically below the 830 m drift.Three drillholes containing macroscale gold grains are separated along strike by 330 m, all at relatively deep depths within the laterally and vertically persistent Revel Ridge Main Zone (RRMZ).Metallic screening indicates that вЂњfree goldвЂќ in these samples may occur in grains which are greater than 106 microns in size, which for the purposes of metallurgy would be classified as coarse particulate grains.Drillhole intersections with these characteristics currently include underground diamond drillholes RR21-28, RR21-36, and RR21-40.

The identification of visible, particulate gold grains in drillholes where significant gold assays are reported and further associated with substantially reduced arsenic concentrations.

The assay results (Table 1) of the metallic screened samples conclusively demonstrate: (TSXRV: RKR) (OTCQB: RKMSF) (FSE: 1RR1) (вЂњRokmasterвЂќ or the вЂњCompanyвЂќ) reports definitive and highly positive assay results from metallic screened samples containing discrete, macroscale gold grains with no significant sulphide association.
