Pretivm Reports Positive Metallurgical Results at Brucejack

May 12. 2011

VANCOUVER, BRITISH COLUMBIA--(Marketwire - May 12, 2011) - Pretium Resources Inc. (TSX:PVG) ("Pretivm") is pleased to report positive preliminary metallurgical results for its wholly-owned Brucejack Project located 65 kilometers north of Stewart, British Columbia.

Based on a combination of gravity concentration and conventional leaching of a bulk flotation concentrate producing dore, precious metal recoveries from the higher-grade Brucejack mineralization are estimated as follows:

-- Gold recoveries range from 92% to 95%, with recoveries increasing with grade for sample grades ranging from 6 grams per tonne gold to 14 grams per tonne gold. -- Silver recoveries range from 73% to 76%, with recoveries increasing with grade for sample grades ranging from 20 grams per tonne silver to 120 grams per tonne silver.

A high-grade West Zone composite sample with a head grade of 77 grams per tonne gold achieved recoveries of 99% gold. The test results demonstrate the potential for excellent recoveries from the high-grade mineralization at Brucejack.

The testwork was conducted at Inspectorate Exploration and Mining Services Ltd., located in Richmond BC, under the supervision of independent consultant Frank Wright, P.Eng. The data is preliminary and subject to confirmation and further variability testing.

Preliminary Economic Assessment

A preliminary economic assessment (PEA) is underway based on the high-grade Brucejack resource which comprises Measured and Indicated resources of 903,000 ounces of gold and 21.92 million ounces of silver (3.67 million tonnes grading 7.66 grams per tonne gold and 185.84 grams per tonne silver) and Inferred resources of 1.90 million ounces of gold and 7.45 million ounces of silver (4.71 million tonnes grading 12.54 grams per tonne gold and 49.24 grams per tonne silver) at a 5.0 gram per tonne gold-equivalent cut-off. The high-grade resource is a subset of the bulk-tonnage Brucejack resource which increased by 134% from 2010 to 2011. (For Brucejack resource estimates see news release dated February 22, 2011). The study has progressed ahead of schedule and is now expected to be completed in June, 2011.

Exploration 2011

Over 50,000 meters of drilling is planned at Brucejack this season, with four drills scheduled to arrive in late May and a second group of four drills arriving in early June. A majority of the drilling will be concentrated on the known areas of high-grade mineralization with the intention of (a) tightening the drill spacing to increase the level of confidence to move Inferred mineral resources to Measured and Indicated mineral resource categories and to improve knowledge of the continuity of the high-grade mineralization for the Valley of the Kings and other high-grade zones (b) testing the high-grade mineralization to depths greater than the current 650 metres and (c) following up on a number of high-grade intercepts encountered in the 2009 and 2010 drill programs that are not sufficiently defined to be included in the high-grade resource.

The camp at site has been opened, and an expansion is underway to accommodate up to 120 people.

About Pretivm
