Pretium Resources Inc.: Bulk Sample Program Continues to Confirm Projection of Mineralized Domains

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Aug 15, 2013) - Pretium Resources Inc. (TSX:PVG)(NYSE:PVG) ("Pretivm") is pleased to report additional underground drill results from the Valley of the Kings Bulk Sample Program (the "Program") currently underway. Assays from the Program continue to confirm the projection of high-grade gold mineralized domains, and visible gold continues to be encountered. (See Table 1 below for assays.)

Selected drill highlights include:

• Hole VU-068 intersected 1,695 grams of gold per tonne uncut over 0.5 meters;
• Hole VU-084 intersected 2,700 grams of gold per tonne uncut over 0.5 meters;
• Hole VU-114 intersected 1,685 grams of gold per tonne uncut over 0.59 meters;
• Hole VU-124 intersected 2,270 grams of gold per tonne uncut over 0.5 meters;
• Hole VU-125 intersected:
  • 1,065 grams of gold per tonne uncut over 5.18 meters, including 10,850 grams of gold per tonne uncut over 0.5 meters; and
  • 3,050 grams of gold per tonne uncut over 0.5 meters; and
• Hole VU-133 intersected 1,945 grams of gold per tonne uncut over 0.5 meters.

The bonanza-grade intercepts noted above were intersected in areas with projected high-grade resources.

Bulk Sample Program

Of the 17 planned drill fans for the Program, assay results have been received for nine fans and four fans remain to be drilled. A total of 163 drill holes have now been completed or in progress comprising approximately 13,750 meters. Approximately 15,000 meters of underground drilling in 190 holes will be completed as part of the Program, which is expected to conclude in early September.

The excavation of the four cross-cuts and one lateral drift planned for the 10,000-tonne bulk sample is nearing completion. Based on available tonnage under the legislated 10,000-tonne bulk sample limit, the lateral drift will now be excavated from 426615E to 426645E crosscuts, with any additional available tonnage to be a drift excavated from 426555E to 426585E crosscuts (in lieu of a drift from 426585E to 426615E crosscuts as originally planned). Bulk sample material excavated to date, approximately 8,600 tonnes, has been processed through the sample tower and is being transported offsite.

Strathcona Mineral Services Ltd. ("Strathcona"), has been engaged as the independent Qualified Person to oversee and report on the 10,000-tonne bulk sample for the Program.

The 1345-meter level, centered at the 426600E cross-section of the Valley of the Kings, was selected as the bulk sample location based on Strathcona's requirements that the bulk sample be excavated from an area representative of the (a) drillhole density that informs the Indicated Mineral Resource, (b) average grade of the Indicated Mineral Resource and the global resource for the Valley of the Kings, (c) proportion of low-grade, high-grade and extreme grade populations in the overall Indicated Mineral Resource and (d) style of stockwork gold mineralization characteristic of the Valley of the Kings.

Additional Drilling

Additional underground drilling and excavating is underway to test the extent of the recently-discovered high-grade Cleopatra Vein in the Valley of the Kings (see news release dated July 23, 2013). Cleopatra has been defined for approximately 85 meters along strike, 50 meters above the 1345-meter level, 50 meters below the 1345-level and remains open in all directions. Underground drilling is also underway to target similar feeder structures. Following the completion of the Bulk Sample Program, a surface drill program is planned to expand the Valley of the Kings resources and test the Cleopatra Vein to surface and for similar feeder structures.

Program Reporting

Assay results for completed fans from the underground drilling will be reported as they are received. Strathcona's report on the Program is expected later in the year after compilation of all data. The amount of gold and silver produced by the mill will be reported following the completion of the milling of the bulk sample.

About Pretivm

Pretivm is creating value through gold at its high-grade gold Brucejack Project, located in northern British Columbia. Brucejack hosts a major undeveloped high-grade gold resource, with Probable Mineral Reserves in the Valley of the Kings totalling 6.6 million ounces of gold (15.1 million tonnes grading 13.6 grams of gold per tonne). Brucejack is being advanced as a high-grade underground mine with an average of 425,700 ounces of gold produced annually for the first 10 years and an average of 321,500 ounces of gold produced annually over the Project's 22-year mine life. Commercial production is targeted to commence in 2016.
