Rokmaster drills 13.4 m of 3.74 g/t AuEq at Revel

2022-01-27 06:29 ET - News Release

Mr. John Mirko reports


Rokmaster Resources Corp. has released the results of the first four drill holes of the continuing 3,000-metre metallurgical drilling program at the Revel Ridge project, located 35 kilometres northeast of Revelstoke, B.C. Revel Ridge hosts a gold-rich, polymetallic orogenic gold deposit and is one of the largest undeveloped deposits of this type in the Western cordillera.

Rationale for 2021 and 2022 metallurgical drill program

The continuing metallurgical drill program utilizes HQ (1) core. Rokmaster's previous drilling in the 2020 and 2021 underground and surface drilling programs used industry-standard NQ core. The metallurgical sampling program is designed to obtain large volumes of mineralized drill core for metallurgical testing. The larger-diameter HQ core produces 62 per cent more volume of material per unit length than NQ (2) core. In the current program, a second drill hole is wedged from the pilot hole, providing Rokmaster with a second mineralized rock volume, with significantly less drilling.

Historically, the majority of the metallurgical studies initiated at Revel Ridge acquired metallurgical bulk samples from the 830 m underground drift. The samples were representative of a few hundreds of metres of strike length of the Revel Ridge Main zone, a gold-rich polymetallic orogenic gold deposit, but only at the 830 m elevation level. Rokmaster's 2020 and 2021 exploration programs have demonstrated that:

  • The mineralized deformation zone that hosts the Revel Ridge deposit is very large. It has excellent continuity over 1,200 vertical m and is known to persist over strike lengths exceeding 3,500 m.
  • The nature of gold mineralization within this large mineralized system may have significant variations in mineralogy, including the potential evolution to a mineralized system with greater amounts of macroscale visible gold (Rokmaster news release dated June 7, 2021).

(1) This is 6.35-centimetre diameter.

(2) This is 4.76 cm diameter.

Rokmaster's current metallurgical program entails drilling approximately 3,000 m of HQ core in 14 drill holes. These drill holes will obtain metallurgical samples from the Yellowjacket, Main, Hangingwall and Footwall mineralized zones. The samples will be used to examine variations in metallurgical characteristics of higher elevation levels (up to 890 m), as well as lower elevations (down to 390 m) within the Revel Ridge mineralized zones. The HQ drill holes in the current program will also obtain samples from over 700 m of strike length of this impressive mineralized system.

Analytical results -- metallurgical drill holes

In addition to conducting metallurgical studies on HQ core samples, HQ drill holes are used to obtain confirmation assays from mineralized zones that may have had limited testing. The results from the first four drill holes in the metallurgical drill program are presented in the associated table. The initial results are significant as:

  • All drill holes hit significant mineralized intervals of the Main (RRMZ), Yellowjacket (RRYZ) and Footwall (RRFZ) zones.
  • All samples significantly exceed the cut-off grades and widths used for inclusion in the revised and updated mineral resource estimate (MRE) (Rokmaster news release dated Jan. 17, 2022).
  • Two of the metallurgical drill holes, RR21-80 and RR21-81, contain macroscale gold in sheeted quartz-iron carbonate veins identified in the Footwall mineralized zone.
  • The updip extension of the mineralized zone in the area of the 830 drift has had very limited drilling. The strongly positive results of DDH RR21-82, drilled 60 m above the 830 adit, suggest significant potential exists in this large, and largely untested, target area.

John Mirko, president and chief executive officer of Rokmaster, stated: "Our current metallurgical drilling program is the first concerted effort in the long history of the Revel Ridge deposits to gain a systematic understanding of the metallurgical characteristics over large areas. Over the past four decades, metallurgical methods and techniques have experienced quantum steps in their ability to cost-effectively deal with gold liberation in high sulphide auriferous gold deposits. Over the past 12 months, Rokmaster's metallurgical team has already raised the benchmark in the process metallurgy of the Revel Ridge ores. We fully anticipate that the current metallurgical drilling program, and the results of these leading-edge metallurgical studies will conclusively demonstrate that cost-effective metallurgical processes are attainable at Revel Ridge. Positive results to those studies will provide the final key to unlock the incredible mineral endowment of the Revel Ridge deposits."

Quality assurance/quality control

Dr. Jim Oliver, PGeo, supervised all aspects of the drilling and sampling undertaken in the 2020 underground diamond drill program. All samples have been collected from one-half NQ core, sawn with a diamond saw with the sample intervals marked by technical personnel. 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 MSA Labs in Langley, B.C. MSA is an International Organization for Standardization 17025-certified (testing and calibration laboratory) and an ISO 9001-certified (quality management system) laboratory. Core samples were crushed to two millimetres and a 250-gram subsample was pulverized with 85 per cent of the sample passing 75 microns. The subsample was analyzed using a combination of MSA Labs FAS211 for Au 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 30 g pulp with an AAS (atomic absorption spectroscopy) finish with a detection range between 0.01 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.

The technical information in this news release has been prepared in accordance with Canadian regulatory requirements as set out in National Instrument 43-101 and reviewed and approved by Eric Titley, PGeo, who is independent of Rokmaster and who acts as Rokmaster's qualified person.
