all amounts discussed are denominated in U.S. dollars

 

Thunder Bay, December 16, 2020 - Premier Gold Mines Limited (TSX:PG) (OTCPK: PIRGF) (“Premier”, “the Company”) is pleased to announce the results of an updated and optimized Feasibility Study for the Hardrock Project (the “Project”) in Northern Ontario. This update was prepared by G Mining Services Inc. with support of several other engineering consultants, summarizing significant optimization and de-risking of the Project. The update is based on a revised mineral reserve, life of mine plan, advances in detailed engineering reflecting firm price bids for all major equipment including the processing plant, mobile fleet, power plant, and the water and sewage treatment plants. The updated study included the mineral resource update released on October 3, 2019.  Premier has a 50% interest in the Project.

 

Highlights of the Study and updated life-of-mine Open Pit Mine Plan (“LOM”) on a 100% basis include:

  • $1.05 Billion After-tax NPV5% based on a US$1,400/oz gold price and a $1.30 CAD to USD exchange rate
  • 20.1 % After-tax Internal Rate of return (“IRR”)
  • 3.2 year Payback Period
  • AISC of $618 per oz and total operating cost of $20.39 per tonne
  • 5.54 Moz of Proven & Probable mineral gold reserves averaging 1.27 g/t Au (0.35 g/t Au cut-off grade)
  • 5.05 Moz Total Gold Produced with a 91.2 % process recovery and 5.1 to 1 strip ratio
  • 358,000 oz LOM average annual gold production
  • 414,000 oz First Five years average production at an average head grade of 1.45 g/t Au;
  • $952 Million Initial capital cost and total LOM sustaining capital of $323 million (Initial capital cost includes working capital and IBA payments);
  • Study does not include upside opportunity from the Hardrock underground mineral resources, nor the Brookbank, Kailey and Key Lake deposits

     

The 39,000 hectare Greenstone Gold Property (the “Property”) is located approximately 275 kilometres northeast of Thunder Bay, Ontario, Canada and is host to a number of historic and recently discovered gold deposits near Geraldton. The Project update contemplates the construction of a 27,000- tonne per day processing facility and open-pit mining operation with production over a 14-year mine life. Gold production during the first five years is expected to average 414,000 ounces per annum with an average head grade of 1.45 g/t gold. The Project timeline accounts for a 20-month pre-production period and a 4-month plant commissioning period. The life of mine (LOM) strip ratio averages 5.1 to 1.

Sensitivity analysis has shown the Project is most sensitive to changes in gold price (see Table 1) followed by exchange rates, initial capital costs and operating costs. The sensitivity to percentage changes in gold grade is identical to that of the gold price and is therefore not presented in the figure. The Project is somewhat less sensitive to the CAD/USD exchange rate than the gold price in USD/oz as some of the CAPEX is in US dollars.

 

Production Profile

The total after-tax cash flow over the Project life is estimated to be $2,089 Million providing an after-tax NPV at a discount rate of 5% is estimated to be $1,050 Million.  The payback period is 3.2 years from the commencement of commercial operations resulting in an after-tax IRR of 20.1%.

Mineral Resources & Reserves

The mineral resource estimate at Hardrock is supported by 312,000 sampled intervals from 696,000 metres of core drilling in 1,682 holes and also nearly 12,000 sampled intervals from 26,000 metres of definition RC-drilling in 481 holes that were completed in 2018 and 2019. In addition to the open-pit constrained Mineral Resource estimate, the Hardrock Project also includes some 1.24 million ounces of Indicated and 3.06 million ounces of Inferred Mineral Resources beneath the proposed Feasibility open-pit that are not included in the project mine plan and may represent an important future mining opportunity. The mineral reserve estimate (see Table 2) includes a 17.2% mining dilution at a grade of 0.13 g/t Au and a 1.5% ore loss factor.

Table 3 summarizes Greenstone Gold Property Mineral Resources exclusive of Mineral Reserves and highlights a potential underground mining opportunity at Hardrock that has not been reported in an economic study. Mineral resources were also updated for the Brookbank, Kailey and Key Lake deposits, collectively known as the “Hardrock Satellite Deposits”. Open-pit optimization using Whittle software, based on the Lerchs-Grossmann algorithm, was completed to estimate in-pit Mineral Resources for the Satellite Deposits and an underground Mineral Resource was also estimated at Brookbank. The Hardrock Satellite Deposits Mineral Resources are effective as of September 3rd, 2020 and there are no mineral reserves currently estimated for these deposits.

Non-IFRS Measures

The Company has included certain terms and performance measures commonly used in the mining industry that are not defined under International Financial Reporting Standards (“IFRS”) within this document. These include: cash cost per ounce sold, all in sustaining cost (“AISC”) per ounce sold. Non-IFRS measures do not have any standardized meaning prescribed under IFRS, and therefore, they may not be comparable to similar measures employed by other companies. The data presented is intended to provide additional information and should not be considered in isolation or as a substitute for measures prepared in accordance with IFRS.
