S pring 20 1 8 11 to acquire and advance the Brucejack project. McNaughton and Konkin moved over to Pretium in January 2011. Over the next few years, Pretium would complete almost 600 more surface drill holes and 800 underground drill holes, numerous academic studies and a bulk sample program to define the existing resource and reserves. Amazingly, fewer than eight years elapsed from the recognition of the deposit in December 2009 until the first gold was poured in June 2017. E.A. SCHOLZ AWARD JOSEPH OVSENEK, DAVID PRINS AND KEVIN TORPY Joseph Ovsenek, David Prins and Kevin Torpy are the recipients of the 2017 E.A. Scholz Award. This award is given to those who have made a significant contribution toward the development of a mining operation in British Columbia and/or Yukon. The Brucejack mine is a 2,700-tonne- per-day high-grade underground gold mine located in northwestern British Columbia, approximately 65 kilometres north of Stewart. With a life-of-mine gold grade of 14.1 g/t, a total gold reserve of 8.7 million ounces, a discounted (five per cent) post-tax net present value of US$1.53 billion and a projected all- in sustaining cash cost of US$446 per ounce of gold, Brucejack is truly one of the top Canadian mining development success stories of the past decade. The Brucejack area had been a focus for exploration by various operators since the 1960s, with extensive drilling and underground development completed at the property's West Zone, near the area of the current mine. Following intersections of bonanza-grade gold mineralization from step- out drilling in 2009 and 2010, Pretium was formed to acquire and advance the project in late 2010. Aggressive drilling programs in 2011 and 2012 continued to demonstrate the presence of high-grade visible gold, so existing underground workings were rehabilitated to facilitate excavation of an underground ramp leading from the historic West Zone area to the new VOK deposit.
