11.0 SAMPLE PREPARATION, ANALYSES, ANDSECURITYInformation in this section has been excerpted from Olssen and Jones (2012c), whichwas sourced from sections within Ghaffari et al. (2012), edited in part and modified.11.1 SAMPLE PREPARATION BEFORE DISPATCH OF SAMPLESUpon completion of the geological logging, the core was moved to the splitting areawhere the core was either split or sawn in half lengthwise using a wet diamond saw. AllPQ core was sawn as the core was too big to fit into the splitters (Figure 11.1). Likewise,any sample intervals that contained visible gold or interesting mineralization were alsosawn. All other core was cracked in half using a standard hammer/blade core splitter.One-half of the drill core was placed in a plastic sample bag with the appropriate sampletag and the other half was returned to its original position in the core box. The samplebags were placed in four or five rice sacks and flown by helicopter to the staging area.Individual work orders generally included between 80 and 120 samples, includingstandards, blanks, and field duplicates. At the staging area, a local expediter brought thesamples to Stewart where the samples were loaded onto a 5 t truck and locked in thecompany’s warehouse for the night. The next morning, the samples were driven to theALS sample preparation facility in Terrace, BC.Figure 11.1Cutting PQ Core at the Brucejack PropertyPretium Resources Inc. 11-1 1291990200-REP-R0012-02Feasibility Study and Technical Report on the BrucejackProject, Stewart, BC
