Feasibility Study and Technical Report - Pretivm

Primary sample gold concentrations were analyzed using fire assay with AA finish. Silver,copper, and an additional 31 elements were analyzed using four-acid digestion with ICPanalysis.Secondary check samples were analyzed using similar analytical methods.The analytical results of the field duplicates, blanks, and standards were reviewed asthey were reported, in order to maintain high-quality results throughout the explorationprogram.Standards and blanks that were determined to have been reported in excess of thedefined acceptable limits for the materials were re-analyzed along with a sample in theirvicinity. This allowed for improvement of any samples with questionable accuracy.In addition, the field duplicates were monitored for sample pairs with poor correlationdue to the nature of the mineralization having localized high-grade narrow veinmineralization. Sample pairs where the duplicate was returned at a much greater gradethan the primary sample, and within the greater than 5 g/t Au category were flagged asbeing in the high-grade region.Pretivm was provided with ongoing documentation of the analytical QA/QC results alongwith updated database exports containing the sample details associated with theanalytical results.Vallat (2012) generated a summary QA/QC report reviewing the analytical results, whichconcluded:The quality assurance and quality control measures taken by Pretivm Resourceshave been sufficient to maintain high quality results.The review of field duplicates, blanks and standards, and check samples hasallowed for inference of a reasonable level of precision, good accuracy, andinsignificant levels of bias within the primary sample results reported by ALSGlobal related to the Brucejack 2012 project including drill holes SU-289 to SU-585.The analytical results can be inferred to be of sufficient quality to represent theproject.11.4 AUTHOR’S OPINION ON DATE SAMPLE PREPARATION, SECURITY ANDANALYTICAL PROCEDURESProcedures undertaken to date by Pretivm have been under the supervision and securityof the issuer’s staff, as far as drill core sampling prior to dispatch. Laboratory samplereduction and analytical procedures have been conducted by independent accreditedcompanies with acceptable practices.Pretium Resources Inc. 11-6 1291990200-REP-R0012-02Feasibility Study and Technical Report on the BrucejackProject, Stewart, BC
