Pretium Resources Inc.: Discovery of the Cleopatra Vein in the Valley of the Kings and Continuation of Bulk Sample Program

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Jul 23, 2013) - Pretium Resources Inc. (PVG.TO)(PVG) ("Pretivm") is pleased to report the discovery of the Cleopatra Vein within the Valley of the Kings and additional underground drill results from the Valley of the Kings Bulk Sample Program (the "Program") currently underway. (See Table 1 below for assays.)

Selected drill highlights include:

  • Hole VU-009 intersected 2,567 grams of gold per tonne uncut over 5.8 meters, including 9,200 grams of gold per tonne uncut over 0.5 meters, 7,180 grams of gold per tonne uncut over 0.5 meters, 10,500 grams of gold per tonne uncut over 0.5 meters and 1,765 grams of gold per tonne uncut over 0.5 meters;
  • Hole VU-013 intersected 2,560 grams of gold per tonne uncut over 0.54 meters;
  • Hole VU-023 intersected 1,405 grams of gold per tonne uncut over 0.5 meters;
  • Hole VU-025 intersected 2,600 grams of gold per tonne uncut over 0.5 meters;
  • Hole VU-032 intersected 4,030 grams of gold per tonne uncut over 0.5 meters; and
  • Hole VU-053 intersected 27,000 grams of gold per tonne uncut over 0.5 meters.

Holes VU-009, VU-013, VU-023 and VU-025 noted above were drilled on section 426615E as part of the Program, along strike of the newly discovered Cleopatra Vein. Holes VU-032 and VU-053 noted above were drilled to test the newly discovered Cleopatra Vein along strike above the 1345-meter elevation.

Cleopatra Vein

The Cleopatra Vein was first discovered while excavating the 6258015N east drill drift in an area of projected extreme grade mineralization by the November 2012 Valley of the Kings Mineral Resource estimate. Cleopatra intersects the 6258015N drill drift at the 426630E cross-section and trends to the south-west where it intersects the 426615E cross-cut and then trends south along section 426615E.

Following the discovery of the Cleopatra Vein, 22 drill holes in five vertical fans were drilled to test Cleopatra's vertical and horizontal continuity and extent. The high-grade gold intersections in the drill holes highlighted above are all understood to be intersections of the Cleopatra Vein. (See Table 1 below for assays of drill holes targeting the Cleopatra Vein.)

The Cleopatra Vein has now 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. Additional underground drilling and excavating is underway to test the extent of the Cleopatra Vein.

The Cleopatra Vein is currently considered to be the deformed manifestation of a fluid conduit that was developed in an extensional fault structure active at the time of volcano-sedimentary basin formation and porphyry system development. The generally east-west trending mineralization seen in the Valley of the Kings is considered to have been fed by fluids passing through these conduits.

Bulk Sample Program

Drill fans on sections 426615E and 426585E have been completed and assays have been received. The drill fan on section 426585E and the other drill fans planned or underway to the west of the 426600E cross-cut are targeting the lower grade populations in the bulk sample location. The drill fan on section 426615E and the other drill fans to the east of the 426600E cross-cut are targeting the higher grade and extreme grade populations in the bulk sample location.

Excavation of the 426585E cross-cut has been completed and the excavation of the 426615E cross-cut is nearing completion. Bulk sample material excavated to date, approximately 5,550 tonnes, has been processed through the sample tower and is being transported offsite. Excavation of the 426645E cross-cut is expected to commence shortly. Planning is underway with Strathcona Mineral Services Ltd. ("Strathcona"), the independent Qualified Person for the Program, to increase the portion of the bulk sample tonnage testing the higher grade blocks in the Indicated Mineral Resource estimate to the east of the 426600E cross-cut and decrease the portion of the bulk sample tonnage to the west of the 426600E cross-cut.

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.

Underground drilling for the Program is on schedule, with a total of 135 drill holes now completed or in progress comprising approximately 10,675 meters. Approximately 15,000 meters of underground drilling in 190 holes will be completed as part of the Valley of the Kings Program.

For a current plan of the development advance of the Program at the Valley of the Kings and cross-sections of the 426585E, 426600E and 426615E drill fans, please visit the following link http://media3.marketwire.com/docs/pvg723_Blk.pdf.

Additional Drilling

With the discovery of the Cleopatra Vein, further underground drilling will be carried out targeting similar feeder structures. In addition, planning is underway for a surface drill program, following completion of the Bulk Sample Program, 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 426,000 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.
