ROKMASTER COMMENCES DRILLING OF SURFACE TARGETS AT REVEL RIDGE
Rokmaster Resources Corp. has commenced the surface diamond drill program at its Revel Ridge project.
The current drill program is primarily directed to efficiently test the Revel Ridge main zone (RRMZ) northwest of the 830 Portal where 2021 surface drilling indicates that there is strong continuity to the RRMZ approximately 515 metres northwest of the 830 Portal.
Drilling will additionally test the Zinc Creek showing, which occurs approximately 920 metres (m) to the southeast of the southernmost 1991 surface drill holes 91-73 and 91-74. Rock samples collected in 2021 from the massive sulphide portion of the Zinc Creek showing assayed up to 7.20 grams per tonne (g/t) gold (Au), 121.0 g/t silver (Ag), 6.55 per cent lead (Pb) and 12.99 per cent zinc (Zn). This style of mineralization is highly characteristic of the RRMZ and is located on strike at a significant distance from previous drilling. The drill program will total approximately 5,000 metres and is designed to expand the volume of the RRMZ as defined in the updated National Instrument 43-101 mineral resource estimate filed on SEDAR on Jan. 17, 2022:
Measured and indicated (M&I): 1.36 million gold equivalent (AuEq) ounces contained within 6.73 million tonnes with an average grade of 6.27 g/t AuEq;
Inferred: 1.22 million AuEq ounces contained within six million tonnes at an average grade of 6.33 g/t AuEq.
Many other prospective targets within the project and surrounding Revelstoke properties will be advanced using mapping, prospecting and geochemical sampling. The extensive field programs completed by Rokmaster over the last two years produced significant rock sample results to revisit and potentially expand upon.
The full assay results from the spring 2022 drill program are expected to be received by the company in the coming weeks and will be published shortly after.
John Mirko, president and chief executive officer of Rokmaster, stated:
"The entire Rokmaster team is excited to be back at Revel Ridge for the surface drill program. We have multiple targets to test with drilling, geological mapping, prospecting and geochemistry within Revel Ridge project and our surrounding Revelstoke properties.
"The ongoing drill program will principally test the RRMZ at depth to the northwest with broad, approximately 100-metre stepouts. These large drill hole stepouts will further test the remarkable continuity and homogeneity of the mineralization in this area. The results of this program will be included in the next resource update, which is planned to be complete in 2023.
"We are also eagerly anticipating the results of the updated PEA, which is scheduled to be complete in the fourth quarter of 2022. This update will apply the 2021 resource estimate (Rokmaster news release, Dec. 1, 2021), in addition to recent metallurgical advancements to the already positive 2020 PEA (Rokmaster news release, Dec. 8, 2020)."
Quality assurance/quality control (QA/QC)
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 assay samples have been collected from one-half NQ core, sawn with a diamond saw with the sample intervals marked by technical staff. A full QA/QC program using blanks, standards and duplicates was utilized to monitor analytical accuracy and precision. QA/QC 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 an ISO 9001 (quality management system) certified laboratory. Drill core samples were crushed to two millimetres (mm) 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 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 50-gram pulp with an AAS (atomic absorption spectrometry) finish with a detection range between 0.01 and 100 parts per million (ppm)). 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.
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.
We seek Safe Harbor.
