June 19, 2014 News Release 14-14 Updated Feasibility Study for Brucejack Project Confirms Positive Economics Vancouver, British Columbia June 19, 2014; Pretium Resources Inc. (TSX/NYSE:PVG) ( Pretivm ) is pleased to announce the results of an updated National Instrument 43-101- compliant Feasibility Study completed by for the Brucejack Project ( Brucejack or the Project ) in northern British Columbia. The report, which includes updated metals prices, currency exchange rate, and costs, confirms the positive economics for a high-grade gold underground mine at Brucejack. Feasibility Study Highlights Increase in Valley of the Kings Mineral Reserve gold grade: o o Valley of the Kings Proven and Probable Mineral Reserves of 6.9 million ounces of gold (13.6 million tonnes grading 15.7 grams of gold per tonne) West Zone Proven and Probable Mineral Reserves of 0.6 million ounces of gold (2.9 million tonnes grading 6.9 grams of gold per tonne); Gold and silver recoveries of 96.7% and 90.0% over mine life; Mine life of 18 years producing an estimated 7.27 million ounces of gold; Average annual production of 504,000 ounces of gold over the first 8 years and 404,000 ounces of gold over mine life; Estimated project capital cost, including contingencies, of US$746.9 million; Average operating costs of C$163.05/tonne milled over mine life; Base case economics: At US$1,100/ounce gold, US$17/ounce silver and exchange rate of 0.92 US$/C$, Brucejack has a pre-tax net present value ( NPV ) at a 5% discount of US$2.25 billion (US$1.45 billion post-tax), a pre-tax internal rate of return ( IRR ) of 34.7%, and a pre-tax payback period of 2.7 years; Alternative high case economics: At US$1,400/ounce gold, US$21/ounce silver and exchange rate of 0.92 US$/C$, Brucejack has a pre-tax NPV at a 5% discount of US$3.54 billion (US$2.28 billion post-tax), a pre-tax IRR of 47%, and a pre-tax payback period of 2 years.

Project Mineral Reserves The Mineral Reserves resulting from the Feasibility Study for the Brucejack Project are based on the December 2013 Mineral Resource estimates for the Valley of the Kings and the West Zone (see news release dated December 19, 2013). The Mineral Reserve estimates by zone and Reserve category are summarized below. Table 2: Valley of the Kings Mineral Reserve Estimate (2)(3) June 2014 Category Contained Tonnes Gold Silver Gold Silver (millions) (g/t) (g/t) (million oz) (million oz) Proven 2.1 15.6 12 1.1 0.8 Probable 11.5 15.7 10 5.8 3.9 Total P&P 13.6 15.7 11 6.9 4.6 (2) Rounding of some figures may lead to minor discrepancies in totals (3) Based on C$180/t cutoff grade, US$1,100/oz Au price, US$17/oz Ag price, C$/US$ exchange rate = 0.92 Table 3: West Zone Mineral Reserve Estimate (4) June 2014 Category Contained Tonnes Gold Silver Gold Silver (millions) (g/t) (g/t) (million oz) (million oz) Proven 1.4 7.2 383 0.3 17.4 Probable 1.5 6.5 181 0.3 8.6 Total P&P 2.9 6.9 279 0.6 26.0 (4) See notes (2) and (3) to Table 2 above.. Mining and Processing Brucejack is planned as 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, will be developed first; the lower-grade West Zone will be developed in the second half of the Project s 18-year mine life. The mine is planned to operate with a processing rate of 2,700 tonnes per day and mine a total of 16.5 million tonnes of ore for the 18 years at an average mill feed grade of 14.1 grams gold per tonne. Mineral processing will involve conventional gravity concentration and sulphide flotation, producing gold-silver doré and gold-silver flotation concentrate. Metallurgical recoveries for the 2

Valley of the Kings are projected to be 96.9% for gold and 84.7% for silver, and for the West Zone 95.1% for gold and 91.0% for silver. A total of 7.27 million ounces of gold and 27.63 million ounces of silver is estimated to be produced over the life of the Brucejack Project, including the gold and silver recovered into the flotation concentrate. The Project s projected production and processing is summarized in Table 4 below.

Capital and Operating Costs The capital cost for the Brucejack high-grade project is estimated at US$746.9 million, including a contingency of US$69.0 million. Capital costs are summarized in Table 5 below.

Additionally, the experience from mining and processing the 10,000-tonne bulk sample from the Valley of the Kings and operating the site year-round for three years has informed the study both on a technical and economic basis. A comparison of the 2014 feasibility study and 2013 feasibility study is summarized below. Increase in overall reserve gold grade and the addition of the Proven Reserves category for the Valley of the Kings; Slightly higher metal recoveries; Mine life decreases from 22 years to 18 years due to higher grade, lower tonnage; Through-put of 2,700 tonnes per day unchanged; 4

Updated metals prices and exchange rate: o o 2014 study uses US$1,100 gold/us$17 silver and 0.92US$:1C$ 2013 study used US$1,350 gold/us$20 silver and 1US$:1C$ Estimated capital cost has increased by 12.6% in US dollar terms, reflecting a depreciation in the Canadian dollar; Estimated capital cost increase primarily related to power, camp size, temporary facilities, water and sewerage treatment, waste disposal, and owner s costs; Unit operating cost has increased nominally. Brucejack will be a high-grade, low-cost producer with average annual production of over 500,000 ounces of gold in the first 8 years, said President and CEO Robert Quartermain. Even in an uncertain gold price environment, Brucejack can deliver high margins, and from a safe jurisdiction. Permitting, Project Timeline, Financing We expect to file our Environmental Assessment Certificate application with the British Columbia Environmental Assessment Office ( BCEAO ) by the end of June. Once filed, the application will be evaluated for completeness over a 30-day period by BCEAO with the involvement of a working group including representatives of First Nations and local governments and other government agencies. Once the application has been accepted, the BCEAO has a maximum of 180 days to complete its review and prepare an assessment report for a decision by the Minister of Environment and the Minister of Energy and Mines. In coordination with the British Columbia provincial permitting process, the Canadian Environmental Assessment Agency will review the Environmental Impact Statement ( EIS ), which we expect to submit this July. Provincial and federal approval of the EAC application and EIS, respectively, allow for the issuance of the statutory permits and authorizations to begin construction of a mine at Brucejack. In consideration of the current permitting status of the Project and the updated construction timeline contemplated in the feasibility study, we now anticipate commercial production at Brucejack to commence in 2017. We will begin the process of evaluating financing options in the fall. The Technical Report for the Brucejack Project Feasibility Study is expected to be filed on SEDAR within 45 days and will also be available at www.pretivm.com.
