Pretium Resources Inc.: 4,195 Grams Per Tonne Gold Over 1.16 Meters Extends Valley of the Kings to the East

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 7, 2012) - Pretium Resources Inc. (TSX:PVG)(NYSE:PVG) ("Pretivm") is pleased to report that step-out drilling has extended the zone of high-grade gold mineralization in the Valley of the Kings to the east by over 100 meters.

The bonanza-grade intercept from a downhole depth of 400.71 meters in hole SU-526 includes:

• 1.16 meters with uncut grades of 4,195 grams of gold per tonne (3.8 feet averaging 122.4 ounces gold per ton).

Additional high-grade intercepts from a downhole depth of 320.5 meters in hole SU-526 include:

• 0.5 meters with uncut grades of 150 grams of gold per tonne (1.6 feet averaging 4.4 ounces gold per ton); and
• 0.5 meters with uncut grades of 752 grams of gold per tonne (1.6 feet averaging 21.9 ounces gold per ton).

Assays for a 440 meter section of hole SU-526 have been received. Assays for the remaining 92 meters of hole SU-526 will be reported as they are received.

Hole SU-526 was collared on section 427000E along strike of the Valley of the Kings. The bonanza-grade gold interval from Hole SU-526 was collared approximately 400 meters southeast of the bonanza-grade gold interval from hole SU-452, which intersected 41,582 grams per tonne gold uncut over 0.5 meters.

The Valley of the Kings now extends over 800 meters in strike length and is open to the east, west, and at depth. An updated plan showing the current extent of the Valley of the Kings from hole SU-498 in the west to hole SU-526 in the east will be posted on our web site, www.pretivm.com. You can also view the plan at the following link: http://media3.marketwire.com/docs/pvg907p.pdf.

Nine drills continue turning at Brucejack, with the 2012 Brucejack Exploration Program expected to be completed early in the fourth quarter.

(1)True thickness to be determined.

(2)Unless otherwise indicated as uncut, all gold assays over 500 g/t were cut to 500 g/t.

(3)Assays pending for the remaining 92 meters of SU-526.

(4)All samples were submitted for preparation and analysis by ALS Chemex at its facilities in Terrace, B.C. All samples were analyzed using multi-digestion with ICP finish and fire assay with AA finish for gold. Samples over 100 ppm silver were reanalyzed using four acid digestion with an ore grade AA finish. Samples over 1,500 ppm silver were fire assayed with a gravimetric finish. Samples with over 10 ppm gold were fire assayed with a gravimetric finish. One in 20 samples was blank, one in 20 was a standard sample, and differing one in 20 samples was a field duplicate one-quarter split core assayed at ALS Chemex in Vancouver, B.C.

Assay results for completed drilling will be reported as they are received over the course of the 2012 drilling season.

Feasibility Study and Underground Program Update

Feasibility Study

The February 2012 preliminary economic assessment examining the economics of the high-grade gold and silver resources at the Brucejack Project (see news release dated February 22, 2012) contemplated the production of gravity and flotation concentrates, which were then refined to produce gold-silver doré. In advancing the feasibility study, a trade-off study has been completed examining the benefits of selling the flotation concentrate to third parties rather than refining the concentrate to produce doré on site. Based on the results of the trade-off study, the decision has been made to advance the feasibility study on the basis that the flotation concentrate will be sold to third parties rather than refined to produce doré on site. With the completion of the September 2012 Brucejack interim high-grade Mineral Resource estimate, the feasibility study is now expected to be completed in the second quarter of 2013.

Underground Program

The underground program is designed, amongst other things, to access the Valley of the Kings deposit on the 1270 meter elevation and demonstrate continuity of the high-grade gold mineralization. The first phase of the underground program, now well underway, will be to slash out the existing West Zone underground workings to five-by-five meters down to the 1330 meter level, a distance of approximately 500 meters. The next phase will be to advance the decline from the 1314 meter level of the West Zone to the 1270 meter level in the Valley of the Kings, a distance of approximately 450 meters. A 10,000 tonne underground bulk sample is expected to be excavated from the 1270 meter level of the Valley of the Kings in the first half of 2013.

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 and mineralization remains open in all directions. A feasibility study for a high-grade underground mine in Brucejack's Valley of the Kings is underway and expected in the second quarter of 2013.
