Pretium Resources Inc.: Valley of the Kings Positive Mineral Resource Estimate Update

VANCOUVER, BRITISH COLUMBIA–(Marketwired – July 21, 2016) – Pretium Resources Inc. (TSX:PVG)(NYSE:PVG) (“Pretivm” or the “Company”) is pleased to report an updated Valley of the Kings Mineral Resource estimate in accordance with National Instrument 43-101 for its Brucejack Project, where construction and development continues on schedule for commissioning of the underground mine in mid-2017.

Updated Mineral Resource Estimate Confirms Geological Model for Mine Production Planning

The 2015-2016 Valley of the Kings infill drill program was undertaken to support production planning in the Valley of the Kings and designed to convert Indicated Mineral Resources into Measured Mineral Resources in the areas to be mined in the first three years of the current mine plan (1320-meter level to 1200-meter level) by increasing drill density to 7.5-meter to 10-meter centers. The program, which consisted of 63,740 meters in 367 drillholes, was successful in increasing the Measured Mineral Resources in the Valley of the Kings by 58% to 1.9 million ounces (3.5 million tonnes grading 17.0 grams per tonne gold).

The program was also successful in adding Indicated Mineral Resources, with Measured and Indicated Mineral Resources in the Valley of the Kings now totalling 9.1 million ounces of gold (16.4 million tonnes grading 17.2 grams per tonne gold), an increase from the December 2013 Valley of the Kings Mineral Resource estimate of Measured and Indicated Mineral Resources which totalled 8.7 million ounces of gold (15.3 million tonnes grading 17.6 grams per tonne gold). Table 1 below is a summary of the updated Valley of the Kings Mineral Resource estimate.

Inferred(2) 4.6 21.0 26.9 3.1 4.0
(1) 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 using 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.
(2) The quantity and grade of reported Inferred resources in this estimation are uncertain in nature and there has been insufficient exploration to define these Inferred Resources as an Indicated or Measured Mineral Resource and it is uncertain if further exploration will result in upgrading them to an Indicated or Measured Mineral Resource category.
(3) Contained metal figures and totals may differ due to rounding of figures.
(4) The Mineral Resource estimate stated in Table 1 is defined using 10 m by 10 m by 10 m blocks in the Valley of the Kings.
(5) The gold-silver cutoff value is defined as Au + Ag/53.

In summary, the updated Mineral Resource estimate has confirmed the geological model for the Valley of the Kings, and combined Measured and Indicated Resources have not materially changed. The Valley of the Kings remains open to the east and west along strike, and at depth.

The Valley of the Kings Mineral Resource estimate has been prepared by Pretivm under the guidance and supervision of Ivor W.O. Jones, M.Sc., FAusIMM, CPgeo who is the independent Qualified Person (QP) responsible for the Mineral Resource for the Brucejack Project. Pretivm employed the same approach and methodology as was used for the December 2013 Valley of the Kings Mineral Resource estimate. For details see Brucejack Project Mineral Resources Update Technical Report effective date 19 December 2013.

Mine Plan Update

With the completion of the updated Mineral Resource estimate for the Valley of the Kings and success in increasing confidence in the estimate in the areas to be mined in the first three years, the Valley of the Kings mine plan will now be updated in preparation for production development expected to commence later this year.
