Pretium Resources was formed in October 2010 with Robert Quartermain as CEO to acquire both the Snowfield and Brucejack projects and advance the high-grade gold Brucejack discovery. Pretium completed its initial public offering on December 21, 2010, and paid Silver Standard US$450 million for Snowfield and Brucejack (US$233 million in cash and US$217 million in shares of Pretium). Silver Standard raised over US$229 million (and a 42.3 % equity interest in Pretium) from the sale of Snowfield and Brucejack and was then positioned to transition to an intermediate gold producer. (It is now SSR Mining Inc.)
Joe, Ken and Michelle departed Silver Standard in early 2011 to join Robert Quartermain at Pretium. Tom was appointed to Pretium’s board of directors as Silver Standard’s nominee. Tom subsequently resigned from the Board in 2015 to take on the role of CFO.
From discovery to production: 2011-2015
Once re-formed at Pretium, the team quickly turned to advancing Brucejack to production. Between 2011 and 2012, 175,000 meters of infill drilling was completed at Brucejack and underground access commenced – all helicopter supported. In the fall of 2011, construction of a 75-kilometer road was commenced to access Brucejack, with the final 12 kilometers crossing the Knipple Glacier. In January of 2013 the road was opened and the development of the underground access to Brucejack’s Valley of the Kings deposit accelerated as bigger equipment was brought in over the road.
In parallel with project work, engineering studies began in earnest in 2011, with preliminary economic assessments on placing Brucejack in production announced in June 2011 and 2012.
Two milestones were achieved in June 2013: the underground development reached the heart of the Valley of the Kings deposit, and the results of a positive feasibility study on placing Brucejack in production were announced. Through the remainder of 2013, the team’s attention was focused on extracting and processing a 10,000-tonne bulk sample to test the deposit. Though there were headwinds caused by the conflicting perspectives of the program’s consultants, and follow-on market turbulence, the outcome was successful. The bulk sample proved that the one-of-a-kind Valley of the Kings deposit, although nuggety, had the makings of a high-grade gold mine.
During 2014 and the early part of 2015, permitting came to the fore with separate processes run for federal and provincial environmental approvals. The support of communities in northwestern B.C. was critical to the success of the Brucejack mine permitting process. Since the early days when Brucejack was managed by the team at Silver Standard, local people from towns and indigenous communities in the area had been part of the growth of the project. Both federal and provincial processes were concluded by June 2015, when an updated feasibility study was also announced. All that remained was to secure construction financing.
Negotiations advanced until September 2015, when a US$540 million private equity-funded construction financing package was announced. In addition to debt, equity and offtake components, the construction financing package included a capped, callable gold and silver stream agreement - an industry first. With the construction financing package announced, mine construction started with a race against the weather to get camp earthworks completed before snowfall.
Construction to Operations: 2016 - 2020
By early 2016, over 1,000 employees and contractors were involved in the construction of the Brucejack Mine, working on surface and underground. While construction ramped up, Grant (2016-2021) joined the team in finance. In the spring of 2016, construction of a 57- kilometer-long transmission line connecting Brucejack to the BC Hydro grid also commenced. The transmission line was a challenge of its own, crossing two glaciers - each with a span of over two kilometers – and at elevations of up to 2,000 meters. These spans are two of the longest – and highest – in North America. To keep up the pace of construction, an additional US$120 million was raised with an equity offering in early 2016 and in March 2017, US$100 million was raised with a convertible debenture offering so that the project was fully funded.
In the first half of 2017, the priority was to safely complete construction on time and on budget with the available funds. The first gold dore bar was poured on June 20, 2017 and commercial production was achieved on July 1, 2017. Over the remainder of the year, Brucejack generated free cash flow and had produced approximately 152,000 ounces of gold during its first six months of ramp-up.
With the mill performing soundly, by year-end 2018, sufficient cash had been generated by Brucejack to repurchase the stream for US$237 million and to refinance the construction debt with a syndicate of banks.
The Brucejack Mine has been consistently generating high cash margins and profits since the start of commercial production. It produced 376,012 ounces of gold at an all-in sustaining cash cost (“AISC”) of $764/ounce in 2018, its first full year of production, 354,405 ounces of gold at an AISC of $888/ounce in 2019, and 347,743 ounces of gold at an AISC of $981/ounce in 2020. In the first three full years of operations, the Brucejack Mine generated US$678 million in free cash flow.
In 2021, Newcrest Mining Limited agreed to acquire Pretium for $3.5 billion.
