VANCOUVER, British Columbia, April 04, 2019 (GLOBE NEWSWIRE) -- Pretium Resources Inc. (TSX/NYSE:PVG) (“Pretivm” or the “Company”) announces an updated Mineral Reserve (the “2019 Mineral Reserve”) and Mineral Resource (the “2019 Mineral Resource”) and Life of Mine Plan (collectively, the “2019 Updates”) for the Brucejack Mine (“Brucejack”), which highlight the continued robust economics of the low-cost, long-life operation.
The 2019 Updates will be detailed in a National Instrument 43-101 Technical Report (the “2019 Report”) prepared by Tetra Tech. The 2019 Report updates the operating parameters contemplated in the Brucejack Feasibility Study entitled “Feasibility Study and Technical Report Update on the Brucejack Project, Stewart, BC” with an effective date of June 19, 2014 (the “2014 Report”) before the mine was constructed and operating, and confirms Brucejack as a low-cost, high-grade gold producer. The 2019 Report will be filed in Canada under the Company’s profile on SEDAR at www.sedar.com and in the United States on the EDGAR section of the Securities and Exchange Commission (“SEC”) website at www.sec.gov, within the coming weeks.
All dollar amounts are expressed in, and references to “$” refer to, United States dollars unless otherwise noted. References to “C$” refer to Canadian dollars.
“Since achieving production at Brucejack we have processed over 1.5 million tonnes of ore and produced over 500,000 ounces of gold, providing us a solid foundation of operating experience and key metrics to update the life of mine plan and outlook for the mine,” said Joseph Ovsenek, President and CEO of Pretivm. “At $1,300 gold, Brucejack now has an estimated after-tax net present value at a 5% discount rate of $2.59 billion over a 14-year mine life. This is a significant increase from the 2017 estimated net present value at a 5% discount rate of $2.10 billion. With Brucejack as our foundation and with our considerable growth profile, Pretivm is well-positioned as a profitable gold producer.”
Summary of 2019 Updates
The updated Life of Mine (“LOM”) plan highlights Brucejack’s low-cost, long life, with the Brucejack Mineral Reserve grade more accurately accounting for internal dilution from transverse longhole stoping.

Summary of 2019 Updates Compared to Prior
The 2019 Updates are based on the six quarters of mining operations at Brucejack since commercial production commenced in July 2017. The Valley of the Kings Proven and Probable Mineral Reserve gold grade has been decreased from 16.1 grams per tonne to 13.8 grams per tonne (a 14% decrease) to account for more internal waste than was anticipated in the Company’s 2016 Mineral Reserve update (see News Release dated December 15, 2016). All estimated costs have been updated with actual costs from 2018. Areas of cost increase include labour, environmental compliance and snow removal. The Net Present Value increase of 23% is attributable to the increase in production from 2,700 tonnes per day to 3,800 tonnes per day.
A comparison of the main parameters of the 2019 Report and prior information is summarized below in Table 2.

2019 Brucejack Mineral Reserve
Brucejack Mine Total Mineral Reserve
The updated Mineral Reserve estimates by zone and Mineral Reserve category are summarized below in Table 3. The 2019 Updates include Mineral Reserve updates for the Valley of the Kings. The West Zone Mineral Reserve was not updated.
Table 3: 2019 Brucejack Mine Total Mineral Reserve(1,2)
|Au (g/t)||Ag (g/t)||Au
|Valley of the Kings Zone||Proven||2.0||11.2||11.8||0.7||0.7|
(1) Mineral Reserves exclude all Mineral Reserve material mined prior to January 1, 2019.
(2) Valley of the Kings Mineral Reserves based on $185/t net smelter return (“NSR”) cut-off grade, $1,200/oz gold, $15.60/oz silver, C$:US$ exchange rate of 1.00:0.78.
Validation of 2019 Mineral Reserve to Actual Mined and Milled Production in 2018
The 2019 Mineral Reserve process was validated by evaluating the complete Mineral Reserve process on the undepleted 2019 Mineral Resource model, creating mining shapes as if no mining had occurred. These generated shapes are referred to as 2019 Reserve Validation shapes. The 2019 Mineral Resource model that was contained within the validation shapes that are broadly coincident with the 2018 actual stope and development ore positions were compared to the 2018 milled and mined results. Applicable validation shapes were determined by the use of Cavity Monitoring Systems (“CMS”) scans of the mined material for 2018. Table 4 below summarizes the comparison.
Table 4: Validation of 2019 Brucejack Mine Mineral Reserve model vs 2018 Actual Production
|2019 Reserve Validation||801||15.4||397||20%||3%|
The tonnage from the validation shapes is 20% less than actual mined while ounces produced are comparable. The primary cause for this is the mining of material outside of the 2019 validation shapes that were originally part of the 2016 Mineral Reserves. This additional material is not encompassed within the validation shapes and therefore would not be a part of the 2019 Reserves if these areas were to be mined again. The inclusion of uneconomic material (waste) within the mined stopes resulted in mining more tonnage at a lower grade in 2018 than would have been mined based on the 2019 Reserve validation shapes.
Mining and Processing
Brucejack is a high-grade underground mining operation using the long-hole stoping mining method and cemented paste backfill. The Valley of the Kings, the higher-grade, primary targeted deposit, has been developed first; the lower-grade West Zone will be developed in the second half of Brucejack’s 14-year mine life. The mine is planned to increase the processing rate from 2,700 tonnes per day to 3,800 tonne per day by year-end 2019 and mine a total of 15.8 million tonnes of ore for the 14 years at an average mill feed grade of 12.6 grams gold per tonne.
Mineral processing at the current operation uses conventional gravity concentration and sulphide flotation, producing gold-silver doré and gold-silver flotation concentrate. The mill will be upgraded to use the same process flowsheet at an increased mill feed rate of 3,800 tonne per day. Predicted metallurgical recoveries over the life of mine average 96.5% and 87.4% for gold and silver, respectively. A total of 6.2 million ounces of gold and 26.0 million ounces of silver are estimated to be produced over the remaining mine life of Brucejack. Projected production and processing is summarized in Table 5 below.

2019 Mineral Resource
Brucejack Mineral Resource
The 2019 Mineral Resource estimate incorporates 76,697 meters of infill drilling in 1,275 drill holes and 18,250 meters of mapped underground development completed in the Valley of the Kings Zone since the 2016 Mineral Resource estimate (see News Release dated July 15, 2016). The updated Mineral Resource reported by zone and confidence category is summarized in Table 10 below. The Valley of the Kings Mineral Resource was updated in 2019, but only in an area where new data was available; the West Zone Mineral Resource was not updated.
Table 10: Brucejack Mineral Resource Estimate (1,2,3,4,5,6)
|Au (g/t)||Ag (g/t)||Au
|Valley of the Kings Zone||Measured||1.8||17.15||16.4||1.0||1.0|
(1) Mineral Resources are reported inclusive of Mineral Reserves.
(2) Mineral Resources which are not Mineral Reserves do not have demonstrated economic viability. The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, marketing, or other relevant issues. 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 and Guidelines prepared by the CIM Standing Committee on Reserve Definitions and adopted by CIM Council.
(3) The quantity and grade of reported Inferred Mineral Resources in this estimation are uncertain in nature and there has been insufficient exploration to define these Inferred Mineral Resources as an Indicated or Measured Mineral Resource. It is uncertain if further exploration will result in upgrading Inferred Mineral Resources to an Indicated or Measured Mineral Resource category.
(4) Tonnes, grade, and contained metal figures in totals may differ due to rounding.
(5) For comparative purposes only, the Brucejack Mineral Resource is reported at a gold equivalent value defined as AuEq = Au + Ag/53.
(6) Mineral Resources exclude all Mineral Resource material mined prior to January 1, 2019.
The 2019 Mineral Resource estimate for the Valley of the Kings Zone differs from the 2016 Mineral Resource estimate in that there are significantly more drill holes used in the estimation of the model, the classification has been adjusted to allow for the change in confidence as a result of the new information, the estimation parameters have been adjusted to allow greater local accuracy of the grade estimates (based on validation of the model estimates against production information), and production volumes have been removed for all production prior to January 1, 2019. This has resulted in a reduction in the number of tonnes in the Measured and Indicated Resource categories. The 2019 Measured and Indicated Resource for the Valley of the Kings Zone is 13.7 million tonnes at 17.2 g/t Au compared to 16.4 million tonnes at 17.2 g/t Au in 2016.

Longitudinal Mining Test Stopes Based on Refined Geological Understanding
The plan for underground development and mining at the Valley of the Kings was based on the initial understanding that the high-grade gold was carried throughout the broad quartz stockwork running nominally east-west. Consequently, the 2014 Report selected transverse longhole stoping as the mining method for the Valley of the Kings, which provided for stopes up to 40 meters wide to be mined across the width of the quartz stockwork corridors.
The experience gained from over six quarters of mining at Brucejack and the Valley of the Kings has led to a refined understanding of the geology and controls on the gold mineralization. The high-grade gold mineralization is now understood to be carried in multiple zones of between 10 to 15 meters wide running nominally east-west within the broader quartz stockwork at the Valley of the Kings.
Based on improved understanding of the geology and controls on the gold mineralization longitudinal longhole stoping, mining along the direction of the corridors of high-grade gold mineralization, may be a better method of mining. Longitudinal longhole stoping will be tested this quarter and is expected to reduce the amount of internal waste within stopes, potentially increasing the average stope grade, and reducing the amount of underground development. If successful, an updated Mineral Reserve and life of mine plan will be prepared for yearend with longitudinal longhole stoping included in the mining method and incorporating the reserve expansion drilling from this year’s drill program.
Production and Cash Flows
Over the next five years, estimated gold production of over 2.6 million ounces of gold will generate cash flows of $1.74 billion, which are more than sufficient to pay down the scheduled debt maturities of approximately $580 million. Capital allocation strategy for 2019 is focused on organic growth and paying down debt. Capital allocation for 2020 and beyond will be addressed later this year.

Scientific and Technical Information
This news release uses the terms “Measured Resources”, “Indicated Resources” (together “M&I”) and “Inferred Resources”. Although these terms are recognized and required by Canadian regulations (under NI 43-101), the SEC does not recognize such terms. Mineral Resources which are not Mineral Reserves 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 guarantee that all or any part of the Mineral Resource will be converted into Mineral Reserves. In addition, “Inferred Resources” have a great amount of uncertainty as to their existence, and economic and legal feasibility. It cannot be assumed that all or any part of an Inferred Mineral Resource will ever be upgraded to a higher category. Under Canadian rules, estimates of Inferred Mineral Resources may not form the basis of feasibility or pre-feasibility studies, or economic studies, except for a Preliminary Assessment as defined under NI 43-101. Investors are cautioned not to assume that part or all of an Inferred Resource exists or is economically or legally mineable.
Cautionary Note to United States Investors
Technical disclosure contained in this news release has not been prepared in accordance with the requirements of United States securities laws and uses terms that comply with reporting standards in Canada with certain estimates prepared in accordance with NI 43-101. NI 43-101 is a rule developed by the Canadian Securities Administrators that establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. Unless otherwise indicated, all Mineral Reserve and Mineral Resource estimates contained in this news release have been prepared in accordance with NI 43-101 and the Canadian Institute of Mining, Metallurgy and Petroleum Classification System. Canadian standards, including NI 43-101, differ significantly from the requirements of the SEC under its Industry Guide 7 (“Guide 7”), and Mineral Reserve and Resource information contained in this news release may not be comparable to similar information disclosed by U.S. companies reporting pursuant to Guide 7. In particular, and without limiting the generality of the foregoing, the term “resource” does not equate to the term “reserves”. Under Guide 7, mineralization may not be classified as a “reserve” unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made and volumes that are not “reserves’ should not be disclosed. Among other things, all necessary permits would be required to be in hand or issuance imminent in order to classify mineralized material as reserves under Guide 7. Accordingly, Mineral Reserves estimates included in this news release may not qualify as “reserves” under Guide 7. Guide 7’s current disclosure standards normally do not permit the inclusion of information concerning “Measured Mineral Resources”, “Indicated Mineral Resources” or “Inferred Mineral Resources” or other descriptions of the amount of mineralization in mineral deposits that do not constitute “reserves” by Guide 7 standards in documents filed with the SEC. United States investors should also understand that “Inferred Mineral Resources” have a great amount of uncertainty as to their existence and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of “Mineral Resources”, “Indicated Mineral Resources” or “Inferred Mineral Resource” will ever be upgraded to a higher category. Under Canadian rules, estimated “Inferred Mineral Resources” may not form the basis of feasibility or pre-feasibility studies except in rare cases. Investors are cautioned not to assume that all or any part of the “Mineral Resources”, “Measured Mineral Resources”, “Indicated Mineral Resources” or “Inferred Mineral Resource” reported in this AIF exists or is economically or legally mineable. Disclosure of “contained ounces” in a resource is permitted disclosure under Canadian regulations; however, Guide 7 normally only permits issuers to report mineralization that does not constitute “reserves” by Guide 7 standards as in-place tonnage and grade without reference to unit measures. Investors are specifically cautioned not to assume that all or any part of the mineral deposits in these categories will ever be converted into Guide 7-defined mineral reserves. In addition, the definitions of “Proven Mineral Reserves” and “Probable Mineral Reserves” under reporting standards in Canada differ in certain respects from the standards of Guide 7. Accordingly, information concerning mineral deposits set forth herein may not be comparable with information made public by companies that report in accordance with Guide 7.
Non-IFRS Financial Performance Measures
The Company has included certain non-IFRS measures in this news release. Refer to the Company’s MD&A for an explanation and discussion of non-IFRS measures. The Company believes that these measures, in addition to measures prepared in accordance with IFRS, provide investors an improved ability to evaluate the underlying performance of the Company and to compare it to information reported by other companies. Management uses these measures for internal valuation for the period and to assist with planning and forecasting of future operations. The non-IFRS measures are intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with International Financial Reporting IFRS. These measures do not have any standardized meaning prescribed under IFRS, and therefore may not be comparable to similar measures presented by other issuers.
