Increases P+P reserves 27%, M+I resources 148% and Inferred resources 917%
ALL AMOUNTS DISCUSSED ARE DENOMINATED IN U.S. DOLLARS
THUNDER BAY, ON, Jan. 19, 2021 /CNW/ – Premier Gold Mines Limited (“Premier”, the “Company”) (TSX: PG) (OTCPK: PIRGF)is pleased to announce the results of a Preliminary Feasibility Study (“PFS” “Report”), with an effective date of December 1, 2020, for the South Arturo Project (the “Project”) located in the heart of the Carlin Trend in Nevada. South Arturo is operated by the Company’s joint venture partner Nevada Gold Mines (40% PG/60% NGM), which is itself a partnership between Barrick Gold and Newmont Mining.
The PFS was prepared by Practical Mining LLC and based on the current mineral reserves, utilizing drilling to November 2019 with a life of mine (“LOM”) plan that includes the underground El Niño Mine and the proposed Phase 1 Open Pit. Mineral Reserves are reported only for material amenable to roasting from the Phase 1 pit and El Niño underground.
All PFS highlights below reflect only Premier’s 40% ownership, unless otherwise stated.
PFS Highlights of the Report include:
- $78.1 Million After-tax NPV5% based on a US$1,400/oz gold price based solely on the El Niño Mine and the Phase 1 Pit
- Phase 1 Pit only – 50% After-tax Internal Rate of return (“IRR”)
- Combined All-in Sustaining Costs (AISC) of $851 per oz
- An increase in Proven and Probable mineral reserves of +27%, Measured and Indicated mineral resources of +148% and Inferred mineral resources of +917% versus December 31, 2018
- Proven and Probable mineral reserves of 350.5koz gold averaging 2.87 g/t Au1
- The PFS does not include the potential of the Phase 3 open pit, heap leach opportunity nor additional underground mining scenarios
- Also does not include the results from the 2020 drill program, targeting expansion of the El Niño underground mine and the potential upgrading of the near-surface mineralization
Premier anticipates that a new mineral resource estimate will be completed in 2021 following receipt of all 2020 drilling results. Following the mineral resource estimate, the Company believes an updated PFS would be justified and should include a trade-off study to determine the merits of developing the Phase 3 pit by underground and/or open–pit mining methods and further refinement of the heap leach opportunities at South Arturo.

The life-of-mine (LOM) after-tax cash flow attributable to Premier is estimated to be $463.4 Million, providing an after–tax NPV5 of $78.1 Million and an after-tax IRR of 50% for the Phase 1 Pit. Highlight financial statistics for the PFS can be found in Table 1.

“While the Pre-feasibility Study currently contemplates mining only a small portion of the overall resources contained on the property, it highlights the robust economics of the project”, stated Ewan Downie, President and CEO of Premier Gold Mines. “Substantial increases in mineral reserves and resources support my belief that South Arturo has the potential to grow for years to come. There continues to be significant potential to increase the mine life by conversion of resources to reserves from the 2020 drilling for both El Niño and Phase 1, and continuing exploration as the deposits remain open for further expansion. Overall, the project economics reflect well on Nevada Gold Mines’ discipline in developing and operating their projects”.
The South Arturo project is a producing mine with low capital requirements, operating costs and robust economics that include a breakeven gold price (at a 5% discount rate) of $811/oz. The project remains economic with up to 40% increases in capital or operating costs and is most sensitive to gold prices (see Table 2), operating and capital costs.

Mineral Resources & Reserves
Mineral Reserves are reported only for material amenable to roasting from the Phase 1 pit and El Niño underground and summarized in Table 3.
Mineral Resources (exclusive of Mineral Reserves) as of December 1, 2020 are presented in Table 4 and include open–pit and stockpile mineralization, oxide mineralization amenable to CIL milling or heap leach processing, and refractory roaster material. Underground Mineral Resources are entirely refractory and require roasting. The underground mineral reserves and resources include all drill results up to November 20, 2019 and until September 12, 2019 for the open pit. Additional drilling was completed in 2020 focusing on expansion of the El Niño deposit at depth and proximal to the Phase 1 and Phase 3 deposits to better define near-surface mineralization, the results of which are not considered in this update.

Mineral Resource Estimate Notes:
- Mineral Resources are exclusive of Mineral Reserves;
- Mineral Recourses are stated as of December 1, 2020;
- Mineral Resources are estimated using variable cutoff grades that are dependent upon recovery and processing method;
- Open Pit Mineral Resources are constrained within a pit shell generated using a gold price of $1,500 per ounce and a silver price of $15 per ounce;
- Underground Mineral Resources are constrained by Mine Stope Optimizer shapes generated using a gold price of $1,500 per ounce and a silver price of $15 per ounce;
- Modifying mill to model factors for tons and contained metal have not been applied to the open pit Mineral Resources;
- Underground Mineral Resources include modifying mill to model reconciliation factors of 1.025 and – 0.901 applied to tons and contained metal, respectively;
- A Mineral Resource is a concentration or occurrence of solid material of economic interest in or on the Earth’s crust in such form, grade or quality and quantity that there are reasonable prospects for eventual economic extraction. The location, quantity, grade or quality, continuity and other geological characteristics of a Mineral Resource are known, estimated or interpreted from specific geological evidence and knowledge, including sampling; and,
- An Inferred Mineral Resource is that part of a Mineral Resource for which quantity and grade or quality are estimated on the basis of limited geological evidence and sampling. Geological evidence is sufficient to imply but not verify geological and grade or quality continuity. An Inferred Mineral Resource has a lower level of confidence than that applying to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration.
