1983 and 1984 Esso continued work on the property and (in 1984) outlined a deposit onthe west Brucejack Zone.1985 Esso dropped the option on the Sulphurets property.1985 The property was optioned by Newhawk Gold Mines Ltd. (Newhawk) andLacana Mining Corp. (Lacana) from Granduc under a three-way jointventure (JV) (the Newcana JV). The Newcana JV completed work on theSnowfield, Mitchell, Golden Marmot, Sulphurets Gold, and Main Copperzones, along with lesser known targets.1986 to 1991 Between 1986 and 1991, the Newcana JV spent approximately$21 million developing the West Zone and other smaller precious metalveins, on what would later become the Bruceside Property.1991 and 1992 Newhawk officially subdivided the Suphurets claim group into theSulphside and Bruceside properties and optioned the Sulphside property(including the Sulphurets and Mitchell Zones) to Placer Dome Inc.(Placer Dome). From 1991 to 1994, joint venture exploration continuedon the Sulphurets-Bruceside property, including property-wide trenching;mapping; airborne surveys; and surface drilling, evaluating varioussurface targets including the Shore; Gossan Hill; Galena Hill; Maddux;and SG zones. Newhawk purchased Granduc’s interest in the SnowfieldProperty in early 1992.1991 Six holes were drilled at the Shore Zone, totalling 1,200 m, to test itscontinuity and to determine its relationship to the West and R-8 zones.Results varied from 37 g/t Au over 1.5 m, to 13 g/t Au over 4.9 m(www.infomine.com).1994 Exploration in the Brucejack area consisted of detailed mapping andsampling in the vicinity of the Gossan Hill Zone, and 7,352 m of diamonddrilling (over 20 holes) primarily on the West, R-8, Shore, and Gossan Hillzones. Mapping, trenching, and drilling of the highest priority targetswere conducted on 10 of the best deposits (including the West Zone).1996 Granduc merged with Black Hawk to form Black Hawk Mining Inc.1997and1998 No exploration or development work was carried out on the Property(Budinski et al. 2001).1999 Silver Standard acquired Newhawk and with it, Newhawk's 60% interestand control of the Property (www.infomine.com).2001 Silver Standard entered into an agreement with Black Hawk wherebySilver Standard acquired Black Hawk’s 40% direct interest in theProperty, resulting in Silver Standard’s 100% interest in the Property.1999 to 2008 No exploration or development work was carried out on the Propertyduring the period from 1999 to 2008.The historical interpretation (Budinski et al. 2001) of mineralized zones in the West Zone,prior to Silver Standard undertaking their exploration work in 2009, is shown in Figure6.1 (underground vein location plan map) and Figure 6.2 (cross-section map).Pretium Resources Inc. 6-2 1291990200-REP-R0012-02Feasibility Study and Technical Report on the BrucejackProject, Stewart, BC
