Mr. John Mirko reports

REVIEW BY METSO OUTOTEC CONFIRMS 96.8% OVERALL GOLD RECOVERY AT REVEL RIDGE

Rokmaster Resources Corp. has received independent metallurgy reports on the recently completed flowsheet development test program on samples from the Revel Ridge project from Base Metallurgical Laboratories Ltd. (BaseMet) and SGS Canada Inc., and a program review report from Metso Outotec Corp.

Overall optimized flowsheet and the BaseMet metallurgical testing report

On average, 98.3 per cent of the feed gold was recovered to the bulk rougher concentrate, and following regrind and sequential flotation, gold recovery to the lead and zinc concentrates averaged 21.1 and 3.6 per cent. Following leaching of the POX residue, performed on the zinc final tail, an additional 72.2 per cent gold was recovered for a total average gold recovery of 96.8 per cent.

Jan Van Niekerk, director, gold process solutions at Metso Outotec, stated: "Metso Outotec's technical review of 2022 Revel Ridge POX test work has indicated that the work has produced a good set of technically competent results and that high sulphide oxidation and subsequent gold dissolution extents were attained during the test work program. The tests were conducted to appropriate standards, and integrity of results lends itself to be used in the design of an industrial POX circuit. We have enjoyed working with Rokmaster and Canenco and look forward to strengthening this relationship as they move forward on the path to production."

Further to the investigation into POX testing for the Revel Ridge project by SGS, Chris A. Fleming, SGS senior consultant, pressure oxidation, commented: "SGS has worked diligently on the development phase of metallurgy with the Revel Ridge project team. The developed flowsheet is ready for further refinement, and we look forward to working with Rokmaster as they advance the pressure oxidation circuit to production."

John Mirko, president and chief executive officer of Rokmaster, stated: "Rokmaster has defined the process flowsheet that significantly improves recoveries of all target metals. Achieving this transformative stage has taken an impressive amount of testing and commitment by the team, and we would like to thank BaseMet, SGS and Metso Outotec for their continued support through this development process. We appreciate their commitment and now move forward to the next phases of engineering."

The technical information in this news release has been prepared in accordance with Canadian regulatory requirements has been reviewed and approved by Stacy Freudigmann, PEng, FAusIMM, who is a qualified person as set out in National Instrument 43-101 and independent of Rokmaster.

About Rokmaster Resources Corp.

Rokmaster is currently conducting a surface 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 preliminary economic assessment technical report dated Dec. 8, 2020, and a technical report of an updated mineral resource estimate on the Revel Ridge property, dated Jan. 17, 2022.

The current mineral resource estimate at Revel Ridge consists of:

  • Measured and indicated: 1.36 million gold equivalent (AuEq) ounces contained within 6.73 million tonnes with an average grade of 6.27 grams per tonne AuEq;
  • Inferred: 1.22 million AuEq ounces contained within six million tonnes at an average grade of 6.33 g/t AuEq.

We seek Safe Harbor.
