A summary of the technical and financial metrics of the PFS is provided in the tables below.

$1,541/oz., a silver price of US $19.60/oz. and a foreign exchange rate of CAD$1 = USD$0.76.  The economics include the effect of the Blackwater gold stream (the “Stream“), which was issued to finance part of the acquisition cost of Blackwater by Artemis from New Gold Inc. (“New Gold“) (refer to news release dated August 24, 2020).  Under the terms of the Stream, New Gold will purchase 8.0% of the refined gold produced from the Project. Once 279,908 ounces of refined gold have been delivered to New Gold, the gold stream will reduce to 4.0%. New Gold will make payments for the gold purchased equal to 35% of the US dollar gold price quoted by the London Bullion Market Association two days prior to delivery.” data-reactid=”29″ type=”text”>The base case economics have been calculated on an unlevered basis, based on a gold price of US $1,541/oz., a silver price of US $19.60/oz. and a foreign exchange rate of CAD$1 = USD$0.76.  The economics include the effect of the Blackwater gold stream (the “Stream“), which was issued to finance part of the acquisition cost of Blackwater by Artemis from New Gold Inc.

  • Starting at 5.5 Mtpa throughput and focusing on the near-surface, higher-grade zone of mineralization in the southern half of the deposit to minimize initial capital cost intensity, improve payback and IRR;
  • Two subsequent expansion stages ramping up to the original planned capacity of approximately 20 Mtpa outlined in the 2014 Feasibility Study, with expansions funded from future operating cashflows;

  • The smaller-scale start-up defers a substantial portion of waste pre-stripping from initial capital, as designed in the 2014 Feasibility Study, into operating costs in the PFS. While this partly contributes to the slightly higher operating costs as compared to the 2014 Feasibility Study, it substantially reduces up front funding requirements and results in a much higher IRR for the PFS;
  • Cost benefits from a smaller, off-the-shelf, modular approach for buildings and crushing equipment;
  • Staged installation of three similar-sized processing trains to 20 Mtpa;
  • Re-designed three-stage crushing with a ball mill provides improved capacity to accommodate variability of ore hardness and maintain name-plate throughput;
  • Reduced overall process footprint and laydown area requirements;
  • Staged tailings capital costs, including relocation of the start-up dam site downstream to optimize initial capacity and haulage distances, improve constructability by following existing access trails in an area of gentler terrain, and simplify water management during early operations;
  • Enhanced water management flexibility with planned installation of a water treatment plant at the start of operations;
  • Total project indirect capital costs and owner’s costs significantly reduced as planned expansions will take advantage of an operating site with installed infrastructure and an established site management team;

The initial design daily throughput is 15,000 tonnes per day, with an availability of 75% used in designing the crushing circuit and 93% for the design of the rest of the plant. 

The process will consist of:

  • Three stage crushing, consisting of a primary jaw crusher with grizzly feeder, a secondary cone crusher and two tertiary cone crushers. The primary jaw crusher, the three cone crushers and the three vibrating screens will each be housed in steel-framed buildings, with covered conveyors transporting material between each stage. The crushed ore stockpile will be covered to prevent freezing;
  • Crushed ore will be conveyed from the stockpile to a single, 7.3 m x 12.5 m, 14 MW ball mill for grinding, with the circuit being closed by cyclones. Gravity concentration will be incorporated into the grinding circuit using centrifugal concentrators and an intensive cyanide leach unit for recovering gold from the gravity concentrate;
  • The leach circuit will consist of eight tanks fitted with mechanical agitators, an initial pre-oxidation tank with cyanide being added to the second and subsequent tanks. The leach residence time will be 48 hours;
  • Carbon in pulp adsorption of gold and silver will be carried out in a “carousel” unit, with “pump cells” moving leached slurry between the six tank units while the carbon remains in the same tank until fully loaded;
  • The loaded carbon will be treated in a Zadra elution and electrowinning circuit consisting of an acid wash column and two elution columns operating at 140 degrees Celsius. A propane heater will provide the necessary temperature and two additional heat exchangers will control the temperature around the circuit. A rotary kiln operating at 700 degrees Celsius will be used to maintain carbon activity. Electrowinning will be carried out to recover gold and silver from the elution solution and the resulting metallic precipitate will be dried and smelted to doré bullion;
  • Cyanide destruction using an SO2 air system will be carried out in the final tailings slurry, with the sulfur dioxide being produced by the combustion of elemental sulfur.

Selling Costs” data-reactid=”162″ type=”text”>Selling Costs

  • Payable factor (Au) of 99.9%
  • Payable factor (Ag) of 95.0%
  • Refining, treatment, transport, and insurance charges of $3/oz.

The Study economics consider two private royalties at 1.0% and 1.5% over parts of the Mineral Reserve.  Estimated payments to Indigenous nations are also included in the economic cash flow model for the Project.

Key provincial and federal tax considerations for Blackwater includes:

  • British Columbia mining tax – 2% provincial minimum tax payable on operating profits immediately upon the start of production which is creditable against the 13% effective mining tax rate which is calculated based on operating profit less applicable capital cost deductions. The mining tax is deductible in computing provincial and federal income tax;
  • British Columbia provincial income tax – 12.0%, payable after applicable deductions are used;
  • Canadian federal income tax – 15.0%, payable after applicable deductions are used.

In the economic results for the Project, the Company presents a base case economic analysis, being unlevered, plus an alternate levered case. The levered case is based on the following assumptions:

  • Initial capital 60% debt financed;
  • Annual interest rate of 5.5%;
  • Upfront financing fee of 3%;
  • 7-year term post commencement of commercial production with a balloon payment of 30% of the principal at maturity;
  • Expansion capital is assumed to be funded through operating cashflow.

Over the next 12 to 18 months, the Company will be focused on the following activities:

  • Completing an NI 43-101 technical report in respect of the Study, which will be filed on SEDAR and on the Company’s website within 45 days of this news release;
  • Commencing a Feasibility Study based on this revised development approach with detailed engineering on the Project;
  • Continuing engagement and negotiations with Indigenous nations who may be impacted by the Project;
  • Completing supplemental geotechnical and hydrogeological site investigation work;
  • Progressing and achieving final permitting required to commence Project construction;
  • Commencing a pre-construction grade control drilling program;
  • Planning for an exploration core drilling program to test for potential extensions of the known mineralization
  • Awarding of lump-sum fixed price EPC contracts in respect of various Project construction components;
  • Arranging of requisite debt and equity financing to support development activities
