VANCOUVER, British Columbia, March 05, 2021 (GLOBE NEWSWIRE) -- Sabina Gold & Silver Corp. (TSX:SBB) (“Sabina” or the “Company”) announces that, it has filed its National Instrument 43-101 Technical Report entitled “National Instrument (NI) 43-101 Technical Report 2021 - Updated Feasibility Study for the Goose Project at the Back River Gold District (“UFS”), effective January 15, 2021 on SEDAR at http://www.sedar.com. The report has also been posted on the Company’s website at www.sabinagoldsilver.com.

“We are pleased to file the NI 43-101 Technical Report for the Goose mine (the “Project”) planned on our 100% owned Back River Gold District,” said Bruce McLeod, President & CEO “We believe the UFS demonstrates a compelling Project, permitted with environmental and social license economic obligations included, that delivers a 15 year mine life with a substantial production profile and robust economics. The study also comes with a level of engineering that significantly de-risks the Project and provides a higher certainty to capital and contingency estimates when compared to most feasibility studies. Also, updated mineral resource and reserve estimates on the Project were announced earlier this year, demonstrating significant opportunity to extend mine life and maintain the production profile beyond the planned 15 years. Our next focus is to continue refreshing the debt process as we move towards Project financing and a production decision. We believe that this UFS presents an opportunity that is only the beginning of production on this highly prospective gold district.”

Project Highlights

On February 24, 2021, the Company announced the positive results of the UFS.  The UFS uses a gold price of US$1,600/oz Au and an exchange rate of 1.31:1.00 (C$:US$). All figures are C$ unless otherwise stated.

Highlights include:

  • A post-tax IRR of 27.7% and NPV (at 5% discount rate) of $1.1 B;
  • A Life Of Mine (“LOM”) post-tax net cash flow of ~$2.0 B on gross revenues of $7.0 B with a payback period of 2.3 years (from start of operations);
  • Average gold production of ~287 koz Au per year for the first 5 years, with a peak gold production of 312 koz in year 3 and ~223 koz Au per year over the 15 year mine life (upon commencement of production);
  • Receipt of all major authorizations with reclamation amounts included in the Project economics;
  • 20-year renewable land use agreements including an Inuit Impact and Benefit Agreements with costs built into the study;
  • Approximately half of mine production to come from open pits with underground production scheduled from year 1 to year 15;
  • Initial capital estimate of $610 million and LOM sustaining capital and closure costs of $419 million;
  • A total LOM cash cost estimate of US$679/oz Au (including third party royalties, refining and transport);
  • LOM all-in sustaining cost estimate of US$775/oz Au LOM (including sustaining capital & closure costs);  
  • A total of 18.7 million tonnes milled over 15 years for a total of 3.35M oz Au with a LOM average grade of 6.0 grams per tonne (“g/t”) Au and LOM average metallurgical recoveries of 93.4%;
  • Base case assumptions of delivered diesel price of $0.91/L for power generation and $0.95/L for mobile and stationary equipment; and
  • Average open pit strip ratio of 10:1 over LOM;
  • Operational flexibility with pre-production stockpile of 2.2 Mt of mill feed on the ground at commissioning; and
  • Elimination of a Tailings Storage Facility and use of mined out pits for tailings deposition.

Project Opportunities

  • Sabina is also in the process of defining a performance guarantee with the Original Equipment Manufacturer for the process plant;
  • High confidence in conversion of further resources into reserves at all deposits with a historical 73% conversion rate. Llama Extension and Nuvuyak deposits are currently inferred resources with a strong probability of effective conversion to reserves;
  • Effective access and potential delineation of additional high-grade material from a planned exploration decline at Umwelt underground;
  • All deposits in the UFS are open to depth with both new resources at Llama Extension and Nuvuyak showing significant expansion potential along trend.
  • With detailed engineering near completion, Sabina is well positioned to engage an experienced Arctic construction team to negotiate lump sum pricing;
  • Sabina has invested in site located data collection units and environmental studies on wind energy and has advanced engagement with companies on alternative energy generation for reduced carbon footprint options; and
  • Additional time, resources and funds for testing, commissioning, start-up and ramp-up have been incorporated into the economic analysis;  
  • Expansion and development of the 1.2 M oz Au of Indicated and1 M oz Au of inferred resources at the George site resource as a second potential mine; and
  • Strong additional discovery potential of new economic gold zones with continued district exploration over the 80km Back River gold belt.

Sabina Gold & Silver Corp.

Sabina Gold & Silver Corp. is well-financed and is an emerging precious metals company with district scale, advanced, high grade gold assets in Nunavut, Canada.

Sabina released a Feasibility Study on its 100% owned Back River Gold Project which presents a project that will product ~223,000 ounces of gold a year (first five years average of 287,000 ounces a year with peak production of 312,000 ounces in year three) for ~15 years with a rapid payback of 2.3 years, with a post tax IRR of ~28% and NPV5% of C$1.1B.

The Project received its final major authorization in June 25, 2020 and is now in receipt of all major permits and authorizations for construction and operations.

In addition to Back River, Sabina also owns a significant silver royalty on Glencore’s Hackett River Project. The silver royalty on Hackett River’s silver production is comprised of 22.5% of the first 190 million ounces produced and 12.5% of all silver produced thereafter.
