Pretium Resources Inc.: Brucejack Project Update

VANCOUVER, BRITISH COLUMBIA--(Marketwired - June 9, 2015) - Pretium Resources Inc. (TSX:PVG)(NYSE:PVG) ("Pretivm" or the "Company") is pleased to announce the following update on the activities underway and planned for 2015 to advance its Brucejack Project.

Brucejack Project Development and Engineering

Underground development in the Valley of the Kings has been progressing, and the first ventilation raise is under development. Detailed mine engineering has been ongoing, and final long lead equipment recommendations have been issued with bids received for a significant portion. Engineering for the transmission line is in the latter stages of completion, with a pole supplier selected and the pole engineering contract awarded. Construction power will be in place for site construction start-up, with bulk earthworks and transmission line construction planned to commence on receipt of permits anticipated this summer.

Valley of the Kings Underground Infill Drill Program

A 40,000-meter infill drill program is underway in the Valley of the Kings (see news release dated June 4, 2015 for initial results.) The program currently comprises 32 drill fans from three drill stations and has been planned to target stope areas in years 1 through 3 of the current mine plan (1,320-meter level to 1,200-meter level). The primary purpose of the drilling is grade control, with the additional benefit of the infill drilling of inferred and non-stope indicated resources in the same area. A second drill is being mobilized to site, with three drills planned in total for the program which is expected to be completed by year-end.

Grass-Roots Exploration Program

A grass-roots exploration program in an area east of the Brucejack Project has now commenced. Targets known as the Flow Dome Zone and Kitchenview Zone (see attached plan) have been selected based on extensive regional exploration conducted by Pretivm including airborne geophysics completed in 2014. The grass-roots exploration program will comprise additional airborne geophysical surveying and a surface drill program of 10,000 to 15,000 meters targeting porphyry/epithermal-style mineralization.

Pretivm's management will present an update of the activities planned and underway to advance the Brucejack Project today, June 9, 2015, at 12:00 pm ET/9:00 am PT with a live audio webcast available at http://services.choruscall.ca/links/pretivm150609.html.
