Pretium Resources Inc.: Significant Increase in Brucejack's Gold Resources
(firmenpresse) - VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 11/28/11 -- Pretium Resources Inc. ("Pretivm") (TSX: PVG) is pleased to report an updated mineral resource estimate for its wholly-owned Brucejack Project located in northern British Columbia. High-grade and bulk-tonnage gold resources have increased significantly as a result of the update.
High-Grade (5.0 grams of gold-equivalent per tonne cut-off) Grade & Tonnage Estimate
Bulk-Tonnage (1.25 grams of gold-equivalent per tonne cut-off) Grade & Tonnage Estimate
Bulk-Tonnage Mineral Resource Estimate (0.30 grams of gold-equivalent per tonne cut-off)
Brucejack High-Grade Project
Mineral Resource Modeling and Estimation
The Brucejack Project comprises seven modeled deposits. The resource models are based on 1,190 diamond drill holes totalling 219,394 metres, which include 452 historical surface drill holes, 442 historical underground drill holes exclusively in the West Zone, and 296 surface drill holes completed since 2009. Mineralization in the SG, Gossan Hill, Galena Hill and Bridge Zones was modelled using Ordinary Kriging, a block size of 25 x 25 x10 metres, and used a top cut for gold between 10 g/t and 30 g/t. The mineral resource estimates for Shore Zone, West Zone and Valley of the Kings Zone used Median Indicator Kriging, and a block size of 25 x 25 x 10 metres. Median Indicator Kriging is a non-linear form of estimation used when the mineralization is shown to be hosted in distinct populations. In this case, the low grade population was defined as all composite samples with Au values below 4.0 g/t gold, and the high grade population was defined as all composite samples with Au values above 4.0 g/t gold. Median Indicator Kriging restricts the contribution of the various sample populations in any given block. As a further restriction, composites in the Valley of the Kings Zone were capped at 900 g/t gold and in the West Zone and Shore Zone were capped at 220 g/t gold prior to grade estimation.
Underground Sensitivity to the Resource Estimate (5.0 grams of gold-equivalent per tonne cut-off)
A sensitivity analysis of the Brucejack underground mining potential was also completed simultaneously with the bulk tonnage Mineral Resource Estimate. For mine planning purposes, the grades in the sensitivity analysis were estimated for the Valley of the Kings and West Zone using 5 x 5 x 5 metre blocks and the same grade estimation parameters as the bulk tonnage Mineral Resource Estimation. The underground sensitivity analysis is not restricted to the Whittle pit shell. The inclusion of the underground sensitivity analysis in this news release is not meant to supersede or replace the results of the bulk-tonnage Mineral Resource Estimate.
"Since acquiring Brucejack 11 months ago, we are very pleased with the substantial progress we have made in outlining the potential for a high-grade underground project," said Robert Quartermain, Pretivm's President and Chief Executive Officer.
The above tables summarize the sensitivities and bulk-tonnage Brucejack Project Mineral Resource Estimate totals. The Mineral Resource Estimate contained in this news release were prepared by Eugene Puritch, P.Eng., F.H. Brown, M.Sc. (Eng.), CPG Pr.Sci.Nat., of P&E Mining Consultants Inc. ("P&E") of Brampton, Ontario, and Caroline Vallat, P.Geo., of GeoSpark Consulting, all of whom are independent qualified persons, as defined by National Instrument 43-101. Mr. Puritch, Mr. Brown and Ms. Vallat have reviewed and approved the contents of this news release.
