Rokmaster drills 4.2 m of 8.84 g/t AuEq at Revel Ridge

2022-11-28 09:39 ET - News Release

Mr. John Mirko reports


Rokmaster Resources Corp. has provided an update on a strong intersection of the Revel Ridge Main zone (RRMZ) by drill hole RR22-102a at the Revel Ridge project.

Drill hole RR22-102a was wedged to completion around the core barrel, which broke due to equipment wear at 222.5 metres. The primary drill hole (RR22-102) intersected strong sphalerite-galena mineralization in a silicified limestone between 206.90 metres and 211.50 metres, representing the Revel Ridge Yellowjacket zone (RRYZ). Notably, this intersection occurs 65 metres from RR21-50, the nearest drill hole hosting RRYZ mineralization. The RRYZ was encountered a second time in the wedge hole (RR22-102a), which is tabulated herein.

The RRMZ is located at the base of a thick carbonate unit at 287.3 metres. Similar to drill hole RR22-101 (see press release dated Sept. 26, 2022), the RRMZ in RR22-102a is primarily developed in a footwall quartzite package. This favourable carbonate-quartzite contact, which supports metre-scale massive sulphide bands in the RRMZ, may be laterally extensive with a distance of 95 metres between RR22-101 and RR22-102a. These broad and successful stepouts are external to the mineral resource estimate block model. Assay results for drill holes RR22-102 and RR22-102a recently received from the laboratory are shown in the attached table.

John Mirko, president and chief executive officer, commented: "Drill hole RR22-102a bolsters the strength of the RRMZ and the Yellowjacket zone in the northwest extension and meets the primary goal of the summer 2022 drill campaign. Rokmaster has located a favourable geological setting hosting wide intersections of RRMZ that is proving to be expansive.

"Work is progressing well on the update to the PEA [preliminary economic assessment] that will be incorporating both the 2021 mineral resource estimate and the recent metallurgical breakthrough that demonstrably improves gold recoveries."

The data from these drill holes will be combined with the spring 2022 drill program and all of the historical drill data to update the mineral resource estimation in 2023.

Quality assurance/quality control

Dr. Jim Oliver, PGeo, supervised all aspects of the drilling and sampling undertaken in the 2021 and 2022 underground and surface diamond drill programs. All drill core assay samples have been collected from one-half NQ core, sawn with a diamond saw with the sample intervals marked by technical personnel. A full quality assurance/quality control program using blanks, standards and duplicates was utilized to monitor analytical accuracy and precision. Quality assurance/quality control samples are submitted approximately at every 20th sample, or a minimum of 5 per cent of the total sample stream. Appropriate standards are used to provide quality control information on high-grade and medium-to-low-grade samples. A limestone blank is inserted after select samples that have macroscale characteristics of higher-grade mineralization. Duplicate samples are repeat analysis of designated primary sample pulps. The samples were sealed on site and shipped to MSALABS in Langley, B.C. MSALABS is an ISO 17025 (Testing and Calibration Laboratory) and ISO 9001 (Quality Management System) certified laboratory. Drill core 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.

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.

About Rokmaster Resources Corp.

Rokmaster's flagship Revel Ridge project is host to a high-grade gold and polymetallic orogenic sulphide deposit, which has been the subject of a PEA technical report dated Dec. 8, 2020, and a technical report of an updated NI 43-101 mineral resource estimate on the Revel Ridge property dated Jan. 17, 2022. The 2022 drill programs are designed to efficiently expand the volume of the Revel Ridge Main zone, as defined by the updated mineral resource estimate, which currently remains open in all directions:

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

We seek Safe Harbor.
