Benchmark Metals Inc. Files Independent Technical Report for Its Multi-Million Ounce Gold-Silver Deposits

30.06.2021  |  Newsfile
Edmonton, June 30, 2021 - Benchmark Metals Inc. (TSXV: BNCH) (OTCQX: BNCHF) (WKN: A2JM2X) (the "Company" or "Benchmark") is pleased to announce, in accordance with National Instrument 43-101 ("NI 43-101") it has filed an independent Technical Report entitled, "Technical Report and Updated Mineral Resource Estimate of the Lawyers Gold-Silver Property, Omineca Mining Division, British Columbia, Canada," with an effective date of June 28, 2021.

On May 14, 2021, the Company announced the Updated Mineral Resource Estimate that provided 2.1 million ounces ("Moz") grading 1.62 grams per tonne ("g/t") gold equivalent ("AuEq") of Indicated Mineral Resources and 821,000 ounces grading 1.58 g/t AuEq of Inferred Mineral Resources. The Mineral Resource remains open for expansion and is amenable to both open pit and underground mining methods. The Technical Report is available for review on SEDAR (www.sedar.com) and on the Company's website (www.benchmarkmetals.com). Benchmark's 2021, 100,000 metre drill program will focus on expanding and defining the deposit areas and include drilling on new high-priority targets that have potential for near surface gold-silver mineralization.

The 2021 drill program will consist of approximately 100,000 metres of drilling, of which 50,000 metres will be for Mineral Resource definition drilling to both expand current Mineral Resources and to upgrade the current Inferred Mineral Resources to Measured & Indicated classifications for inclusion in an anticipated Feasibility Study in 2022. In addition to expanding the Mineral Resource zones at depth and along strike, a regional exploration program will consist of ~50,000 metres to drill test and expand existing and new discovery targets. The regional program has potential to add gold-silver ounces in an updated Mineral Resource Estimate for 2021.

  1. Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues. There is no certainty that Mineral Resources will be converted to Mineral Reserves.
  2. The Inferred Mineral Resource in this estimate has a lower level of confidence than that applied to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of the Inferred Mineral Resource could be upgraded to an Indicated Mineral Resource with continued exploration.
  3. The Mineral Resources in this news release were estimated in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum (CIM), CIM Standards on Mineral Resources and Reserves, Definitions (2014) and Best Practices Guidelines (2019) prepared by the CIM Standing Committee on Reserve Definitions and adopted by the CIM Council.
  4. Mineral Resource estimation parameters used were as follows:
    1. Total database of 696 drill holes with 77,175 assays
    2. 65 mineralized domains
    3. 5m x 5m x 5m block model
    4. One metre capped composites
    5. Inverse distance cubed grade interpolation for Indicated used minimum of three composites from two holes
    6. Average bulk density of 2.67 t/m3
    7. Average respective Indicated and Inferred classification search ranges of 35m and 65m
  5. Metal prices used were US$1,600/oz Au and US$20/oz Ag and 0.80 FX with process recoveries of 90% Au and 83% Ag. A C$24/tonne process cost and C$5 G&A cost were used. The Au:Ag ratio was 90.5:1.
  6. The constraining pit optimization parameters were C$3/t mineralized and waste material mining cost and 50-degree pit slopes with a 0.50 g/t AuEq cut-off.
  7. The out-of-pit parameters were at a C$100/t mining and $15/t sustaining development cost. The out-of-pit Mineral Resource grade blocks were quantified above the 2.0 g/t AuEq cut-off, below the constraining pit shell and within the constraining mineralized wireframes. Out-of-Pit Mineral Resources selected exhibited continuity and reasonable potential for extraction by the long hole underground mining method. Isolated, non-contiguous blocks were removed.

Quality Assurance and Control
Results from samples were analyzed at ALS Global Laboratories (Geochemistry Division) in Vancouver, Canada (an ISO/IEC 17025:2017 accredited facility). The sampling program was undertaken by Company personnel under the direction of Rob L'Heureux, P.Geol. A secure chain of custody is maintained in transporting and storing of all samples. Gold was assayed using a fire assay with atomic emission spectrometry and gravimetric finish when required (+10 g/t Au). Analysis by four acid digestion with 48 element ICP-MS analysis was conducted on all samples with silver and base metal over- limits being re-analyzed by atomic absorption or emission spectrometry. Rock chip samples from outcrop/bedrock are selective by nature and may not be representative of the mineralization hosted on the Project.

Michael Dufresne, M.Sc, P.Geol., P.Geo., and Eugene Puritch, P.Eng. of P&E Mining Consultants Inc. are the Qualified Persons, as defined in National Instrument 43-101 Standards of Disclosure for Mineral Projects, who have reviewed and approved of the scientific and technical disclosure in this news release. Mr. Puritch is independent of the Company.
