Our Company, Our Mine

About Pretivm

Headquartered in Vancouver, with a regional office in Smithers, Pretium Resources Inc. (“Pretivm” or “the Company”, TSX/NYSE: PVG) is an intermediate Canadian gold producer.

At Pretivm, our goal is to create and share value through gold. This goes beyond monetary profits or a return on investment for our shareholders. It includes value for neighbouring communities and First Nations, for families, for local businesses, and for the regional economy of Northwest BC.

The Brucejack Mine

Pretivm owns and operates the underground Brucejack Mine located 65 kilometres north of Stewart, BC. Construction began in 2015 and commissioning and commercial mine production were achieved in 2017. The planned operational life of the mine is 13 years, followed by a five-year closure phase including decommissioning, reclamation, and environmental monitoring activities.

In addition to the surface mine site, the Mine also includes underground mine works, a 73.5-kilometre access road connecting to Highway 37, and a transmission line connecting to the provincial power grid. Portions of the Mine and associated infrastructure lie within the traditional territories claimed by the Tsetsaut Skii km Lax Ha (TSKLH) and Tahltan Nation, and in the Nass Area of Nisga’a Nation as defined in the Nisga’a Final Agreement.

At the Brucejack Mine, we have an enclosed, on-site plant for processing ore into gold and silver doré bars and flotation concentrate. The mine site also includes full-service camp accommodations, with private rooms, a catered dining hall and facilities for recreation, entertainment, and telecommunications. As of December 2019, we had 763 direct employees and 348 on-site contractors. Employees and contractors primarily work on a two-week shift rotation and access the mine site by road.

The Brucejack Mine is located in a remote and geographically challenging landscape. Pretivm understands that our activities can directly affect our natural environment—and we also know that the natural environment can affect our activities. The journey to the Brucejack Mine includes a 12-kilometre traverse of the Knipple Glacier, and we use vehicles designed to operate safely on the glacier. Our direct interaction with the natural environment is top of mind everyday as we work to protect the natural environment while supporting local employment and economic benefits.

Sharing the Value of Gold Made in BC

We are proud to be a company Made in BC, producing gold that is Made in BC, and using local businesses and services. Local hiring and the involvement of local businesses has always been a priority, and we are pleased to maintain the involvement of local suppliers.

From the Brucejack Mine, gold and silver concentrate is transported by truck to the Port of Stewart, where it is loaded onto bulk carrier vessels for shipping to smelters in Asia and Europe. Our doré bars are flown from the site to international smelters or traders. Gold from the Brucejack Mine ultimately becomes part of the global gold market managed by central bullion banks.

Timeline

2016

 

More than 900 direct and contracted workers were involved in construction in the summer of 2016, including completion of the camp, erection of the mill building, and ongoing construction of the mine portal, underground mine, and transmission line.

March 2017

 

Following completion of the 57 km transmission line connecting the mine site to the provincial electricity grid, we energized the transmission line in March 2017.

June 2017

 

We commissioned the process plant in June 2017 and poured the first gold from the Brucejack Mine.

July 2017

 

On July 3, 2017 we formally announced the start of commercial production at Brucejack.

October 2017

 

Pretivm signed a Cooperation and Benefits Agreement with the Tahltan Nation in October 2017. We reached a comparable agreement with the Nisga’a Nation in 2015.

December 2017

 

In December, we submitted an application to provincial regulators to amend our permits to increase the Brucejack Mine production rate from 2,700 to 3,800 tonnes per day.

February 2018

 

We commenced a data-driven, iterative grade control program in February 2018 to refine our mining and optimize our production. The grade control program was fully implemented into our mining process by April, and it continues to be refined and updated with the benefit of additional data through ongoing production.

July 2018

 

A year after the start of commercial production, Pretivm was proud to announce that the Brucejack Mine had achieved steady-state production.

December 2018

 

We received amended permits from the BC Ministry of Energy, Mines and Petroleum Resources and BC Ministry of Environment and Climate Change Strategy in 2018. These amended permits allowed us to increase mine production to 3,800 tonnes per day.

December 2019   

In 2019, we focused on advancing underground development and grade control to optimize production at the increased production rate.

2020 (Looking Ahead)   

In 2020, we continue to operate at the new production level while focusing on the health and safety of our staff and communities during the COVID-19 pandemic.

 

Grassroots Exploration Program

Ongoing exploration is an important part of our business so that we can identify opportunities for organic growth and expansion. In 2019, regional grassroots exploration continued on the 1,250-square kilometre Bowser Regional Property that surrounds the Brucejack Mine. The 2019 exploration program included 19,850 metres of drilling, completed by four drills. Drilling focused on testing high-priority targets across the Bowser Property, including potential Eskay Creek-style volcanogenic massive sulphide deposits and high-grade, epithermal-related gold systems.

Industry Involvement

Pretivm is a member in good standing of the Mining Association of BC (MABC) and the Association for Mineral Exploration British Columbia (AME BC).

Highlight Story

Evaluating Options for Electrification

Pretivm has made a significant investment to connect the Brucejack Mine with the provincial electricity grid, providing clean and renewable energy for many aspects of the Mine. However, underground mobile equipment remains reliant on diesel fuel. We recognize that the electrification of our underground fleet could provide both environmental and financial benefits, including a reduction of greenhouse gas emissions and an improved working environment for underground workers.

In 2019, Pretivm completed studies at the prefeasibility level to determine the technical and economic feasibility of converting some of the underground mobile equipment to battery electric vehicles. Based on positive results of the study, we plan to begin operating one battery electric haul truck on a trial basis. The haul truck has a 50-tonne capacity and will displace 1,580 tonnes of scope 1 GHG emissions on an annual basis, compared to an equivalent conventional diesel vehicle. A successful trial program will promote the case for further investment in this technology over the next several years.

With the Brucejack Mine’s existing connection to the provincial grid, we believe that Pretivm is well positioned to reduce our reliance on fossil fuels and further contribute to Pretivm being a low-carbon gold producer.
