Pretium Resources Inc.: Bulk Sample and Exploration Drilling Update

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Sept. 23, 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, as well as additional exploration drilling in the Valley of the Kings extending beyond the area of the Program. Assays from both Program and non-Program exploration underground drilling continue to confirm the projection of high-grade gold mineralized domains, with numerous intersections encountering gold grading over 1,000 grams per tonne. (See Table 1 below for assays.)

Selected drill highlights include:

  • Hole VU-201 (Exploration hole) intersected 6,550 grams of gold uncut over 0.50 meters;
  • Hole VU-219 (Program hole) intersected 698 grams of gold uncut over 2.97 meters including 2,340 grams of gold uncut over 0.50 meters and 1,805 grams of gold uncut over 0.50 meters;
  • Hole VU-221 (Program hole) intersected 66 grams of gold uncut over 13.00 meters including 1,675 grams of gold uncut over 0.50 meters;
  • Hole VU-239 (Exploration hole partially intersecting Cleopatra Vein) intersected 195 grams of gold per tonne uncut over 9.29 meters including 2,140 grams of gold uncut over 0.50 meters and 1,425 grams of gold uncut over 0.50 meters.

Seven high-grade gold intersections in the latest results exceed 1,000 grams per tonne, including one intersection of the Cleopatra Vein (the 2,140 grams per tonne gold intersection uncut from hole VU-239 noted above). Hole VU-201 noted above was drilled as an exploration hole from the 426622.5E drill bay to the north.

Bulk Sample Program

Assay results have been received and reported for 15 of the 17 planned drill fans. A total of 186 drill holes have now been completed or in progress comprising approximately 15,418 meters. Approximately 16,500 meters of underground drilling in 202 holes will be completed as part of the Program, which is expected to conclude in September. The final fan of the underground drilling included in the Program is in progress and expected to be completed this month.

For cross sections and plan views of the currently reported drilling please visit the following link - http://media3.marketwire.com/docs/pvg923_F1-4.pdf.

The 10,000 tonnes of bulk sample material has been transported offsite. Approximately 6,000 tonnes of bulk sample material will have arrived at the mill by the end of this week with the remaining material scheduled to arrive by the end of October. Milling of the bulk sample material will commence later this week.

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 Underground and Surface Exploration

Excavation of a drift along the recently-discovered high-grade Cleopatra Vein in the Valley of the Kings has been completed, with two raises on Cleopatra underway. 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. Additional drifting and cross-cutting has been completed in two areas: to the west of the bulk sample location, and to the north and east on Domain 20. Planning is underway for additional drifting.

Underground exploration drilling is currently testing high-grade mineralization to the west, east and below the bulk sample location. Approximately 13,500 meters of underground exploration drilling is expected to be completed in addition to the 16,500 meters of drilling included in the Program, with approximately 12,000 meters of underground exploration drilling completed to date.

The surface drill program at the Valley of the Kings is underway with two drills on-site and targeting high-grade mineralization in the Valley of the Kings to the east of the bulk sample location. A total of 5,000 meters is currently planned for the surface drill program.

Program Reporting

Assay results for completed fans from the underground drilling will be reported as they are received. Due to the projected time to complete assaying of the samples from the sample tower, Strathcona's report on the Program is now expected early in 2014 after compilation of all data. The amount of gold and silver produced by the mill will be reported as milling of the bulk sample progresses.

Feasibility Study Update

The Brucejack Project Feasibility Study (see news release dated June 11, 2013), and associated mine plan and Mineral Reserves, will be updated following the completion of an updated Mineral Resource estimate for the Valley of the Kings. The updated Mineral Resource estimate for the Valley of the Kings will incorporate all 2013 underground and surface drilling and will be prepared following receipt of all assays for the 2013 drill program.

(1) True thickness to be determined.
(2) Unless otherwise indicated as uncut, all gold assays over 430 g/t were cut to 430 g/t.
(3) 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.

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.
