Value Through Gold



Made in British Columbia
As a proud corporate citizen of British Columbia, Pretivm is focused on ensuring that the safe, successful operation of the Brucejack Mine benefits the province, in particular the communities along the Highway 37/16 corridors in the region of the mine. This area includes the communities of Dease Lake, Stewart, Terrace, Smithers, Hazelton and New Hazelton.

Of our many First Nations neighbors in this area, Pretivm's formal engagement process includes the Tsetsaut/Skii km Lax Ha, Tahltan Nation and Nisga'a Nation. The Tsetsaut/Skii km Lax Ha comprises approximately 30 members, with most members based in and around Hazelton and New Hazelton.

The Tahltan Nation's approximately 5,000 members reside in on-reserve communities in Telegraph Creek, Iskut and Dease Lake and in other communities in North America. The Tahltan are represented by the Tahltan Central Government, the central administrative governing body for the Iskut Band and the Tahltan Band.

The Nisga'a Nation's approximately 7,000 citizens live in the four Nisga'a villages of Gitlaxt'ammiks, Gitwinksihlkw, Laxgalts'ap and Gingolx, and in the communities of Terrace, Prince Rupert/Port Edward, Greater Vancouver and elsewhere in North America. Nisga'a Lisims Government represents the Nisga'a Nation, which is governed according to the terms of the Nisga'a Final Agreement, British Columbia's first modern treaty.

The Brucejack mine site workforce includes citizens who have identified themselves from over 10 different aboriginal groups in British Columbia.

We are committed to maintaining positive relationships with our neighbors, rigorous environmental stewardship and a high standard of health and safety. We view these commitments as interrelated, and the responsibility for their conduct and oversight is shared by Pretivm’s Board of Directors and senior management.


Community Engagement in the Northwest
Pretivm’s relationships with the citizens of northwestern British Columbia have been positive and mutually-beneficial since the earliest exploration stages at Brucejack, when we made it a priority to hire and source locally for our exploration camp.  During the subsequent years of permitting and construction, we found sustained support in the region for the development of Brucejack as an underground mine. We value the opportunities to continue the community engagement which has earned us this support.

Pretivm’s Social Responsibility Policy describes the principles that guide our activities in the area of community relations, and the policy is framed by two detailed management plans under our permits that govern the formal aspects of relationship management. The Economic and Social Effects Mitigation Plan addresses the scope of our initiatives for employment, training and contracting in the region, and the Aboriginal Consultation Plan outlines our communication plans and commitments in the area of First Nations engagement. 

The design, development and construction of the Brucejack Mine involved extensive and ongoing consultation with local Aboriginal groups, all levels of government in Canada and the state of Alaska, as well as the general public. This process of engagement and consultation ensures that the conduct of our project activities meets the expectations set out in our Environmental Assessment Certificate and related conditions, and has established the framework for ongoing dialogue to ensure community concerns are understood and addressed appropriately. 

We maintain engagement with communities by:

  • Hosting community events and open houses to provide updates, respond to questions, promote job opportunities and offer insight into mine site work for the benefit of potential employees and their families;
  • Participating in regional economic development initiatives;
  • Supporting and attending local cultural events;
  • Direct outreach to local communities and educational institutions by our Community Relations Manager;
  • Maintaining a local presence and central point of contact through our office in Smithers.

Employment & Training
We are committed to hiring locally for all positions whenever possible, and work directly with community employment coordinators to connect locals with job opportunities at Brucejack, and support their continued success. The total mine site workforce includes approximately 500 people (including employees and contractors) working on rotation in management, trades, logistics, underground mining, milling and a spectrum of mine and camp support roles.

Although the Brucejack Mine is relatively small in scale, we are striving to leverage our role in the region for meaningful and long-lasting benefit. We are working in partnership with relevant government and educational institutions in northern British Columbia to identifying gaps in local labour force capacity where we can focus training and development strategies.  Our shared goal is to prepare workers for roles in mining and beyond, and foster the transferrable skills which will benefit the region for the longer term. 

Economic Benefits for northern British Columbia
Pretivm has been a corporate citizen of northern British Columbia since it was first formed in late 2010 to advance the Brucejack project.  As Brucejack grew in scope, so did the need for supplies and services, which has benefitted the businesses in the region. Many of these businesses are based in the commercial centres of Terrace and Smithers as well as the district of Stewart, New Hazelton, and other surrounding communities.  We have sourced locally for food and fuel for Brucejack camps, as well as office supplies and vehicle renting and leasing.  We have engaged local companies who provide services related to road maintenance, transportation, medical response, electrical trades, environmental controls and monitoring, drilling, camp buildings and supplies, as well as construction-related contracting including steel supply and installation.  We will continue to look first to local suppliers as part of our procurement strategies during operations.


Environmental Stewardship
The Brucejack Mine has been developed in accordance with stringent federal and provincial requirements to protect the natural environment throughout the course of exploration, mining, processing and closure activities.  These requirements address our compliance with regulatory standards, mitigation measures, and the pursuit of optimal practices for operating our mine, camps and access road.  Canadian Environmental Assessment Agency (CEAA) documentation related to the Brucejack Mine can be accessed from the Canadian Environmental Assessment Registry website

Environmental Management System
Pretivm has developed Environmental Management Plans (EMPs) to operate Brucejack in a manner in accordance with our corporate Environmental Policy and regulatory requirements.

The primary EMPs include plans for management of water quality and aquatic effects; air quality; metal leaching and acid rock drainage (ML/ARD); wildlife; vegetation; and heritage resources, as well as plans for emergency spill response; chemicals and materials storage and handling; waste management; invasive plants management; and chemicals management plans for the mine water treatment plant. 

Water and air discharges from the mine are closely monitored internally and through independent parties.  Water quality and flows are monitored both at the points of discharge and at multiple locations in the downstream receiving environment.  Additional aquatic effects monitoring of both the downstream environment and a reference site is conducted and assessed to confirm that the downstream aquatic receiving environment is not being affected by our activities.  There is also monitoring in effect for any impacts on vegetation and wildlife.  The monitoring regime for Brucejack extends through the mine life and closure stages.

Environmental Conservation – Design Choices
The efficient use of energy, resources and materials is integral to the design and operation of our facilities.  Conservation efforts in the development of the Brucejack Mine included:

  • Connection to the BC Hydro transmission grid to access hydro-electric and natural gas power resulting in reduced greenhouse gas emissions;
  • The use of electric heaters in place of traditional propane heaters to reduce greenhouse gas emissions;
  • The installation of variable frequency electrical drives to increase the efficiency of the mill facility and reduce power consumption;
  • The installation of a pebble crusher to further grind ore in order to increase efficiency of the ball mill;
  • The installation of LED high-bay lighting in the mill building to reduce energy usage; and,
  • The installation of a state of the art water treatment facility for construction and operations.

Continuous Commitment
We require that all employees, contractors and suppliers comply with our corporate commitments to protect the natural environment, and to that end we provide them with the resources and training necessary to fulfill their responsibilities. We encourage dialogue on environmental issues with all of Brucejack’s stakeholders concerning opportunities to improve our performance in this area.

Health and safety

Safety by choice, not chance
Human health and safety is the primary consideration governing our activities at the Brucejack site and our corporate offices. Pretivm’s safety management initiatives emphasize effective safety leadership, accountability, and a proactive approach to risk recognition. 

Safety awareness education is conducted at Brucejack on a daily basis to instill the competency in our workforce to identify, understand, and manage risk in the remote site operating environment.  On-the-job training related to safety at Brucejack is continuously provided to Pretivm employees, including basic first aid, food safe, the workplace hazardous materials information system, mine rescue, avalanche training, and other relevant topics.  The Brucejack Drug and Alcohol Policy forbids the consumption or possession of alcohol or illegal drugs at site, and supervisors are trained to identify drug and alcohol use on the job.  Pretivm offers an Employee Assistance Program which provides additional health and wellness support on and off the Brucejack site.

Frequently Asked Questions


What kind of mine has been developed at Brucejack?

Brucejack is a high-grade underground gold mine. Commercial production was announced on July 3, 2017.

back to top

How big is the mine at Brucejack?

In 2018 Pretivm has been permitted to increase production by 40% from 2,700 to 3,800 tpd. The area of mine site itself, including the camp, covers approximately 10 hectares.

back to top

What does the mine produce?

Brucejack produces predominantly gold with some silver. About 50% to 60% of the gold is produced as gold-silver doré bars, and the remainder is produced as a gold-silver concentrate.

back to top

How is the ore extracted?

The mining method at Brucejack is long-hole stoping. This bulk underground method was chosen because the deposit is characterized by stringers of high-grade gold disseminated throughout lower grade gold (0.5 to 2.5 grams per tonne) quartz stockwork. Horizontal drifts are driven along two sublevels, and rock is blasted vertically from the upper level to the lower level along strike. The stope void left behind is then back-filled with waste rock and tailings mixed with cement.

back to top

How is the ore processed?

The extracted rock is dumped into an underground crusher (which reduces dust and noise in the open air), crushed, and conveyed to surface. It is then put through a grinding circuit where it is ground to 75 microns. This material then goes through a gravity concentrator to extract the free gold, from which we will produce gold-silver doré bars. The remaining rock is processed in flotation cells and concentrated down to less than 10% of its initial mass. This is the flotation concentrate which is trucked from site and sold to smelters and metals traders.

back to top

Where is the ore transported, and how?

The gold-silver doré bars are flown out from site and sold to refiners. The concentrate is trucked out and either transported by rail or ship to end buyers.

back to top

When did the mine begin commercial production?

Commercial production at Brucejack Mine was announced on July 3, 2017.

back to top


Does the mine use cyanide?

No. In processing, the majority of the gold is liberated through grinding and gravity separation. The remainder is separated through a conventional flotation process.

back to top

Where does the mine’s waste rock go?

During the initial development of the mine, waste rock (estimated at approximately 2 million cubic meters, subject to the feasibility study) will be deposited in Brucejack Lake, an approximately 100-meter deep lake with an estimated volume of over 30 million cubic meters. Once stope voids have been developed from operations, waste rock will be deposited back underground.

Waste rock from historic underground development at the property was deposited in Brucejack Lake as part of reclamation in 1999. Brucejack Lake is not fish habitat, and no fish have been captured there historically or in 2010 and 2011 surveys.

back to top

What about tailings from the mine?

Up to 50% of the tailings from the Brucejack mine (estimated at approximately 6 million cubic meters, subject to the feasibility study) are to be deposited in the bottom third of Brucejack Lake, with the remaining 50% to be used for paste backfill and deposited back underground. Studies are underway to maximize the amount of tailings to be placed underground.

back to top

Will the mine impact area waterways?

The mine at Brucejack is not expected to impact the area waterways. Brucejack Lake is a glacial lake with minimal turnover. Its outlet is Brucejack Creek, which flows west under Sulphurets Glacier, into Sulphurets Creek (~7 kilometers away), and then ultimately to the Unuk River (~20 kilometers away), where it has minimal contribution. The Brucejack Creek watershed comprises approximately 3.5% of the Unuk River watershed.

back to top

Are there fish in the vicinity of the mine?

Brucejack Lake does not support fish and is not considered fish habitat. It is at high elevation and is covered by ice approximately 10 months of the year. Its outlet is Brucejack Creek, which flows west downstream ultimately into Sulphurets Creek. There is an approximately 200-meter barrier (waterfall) on Sulphurets Creek located approximately 20 kilometers from Brucejack Lake which prevents fish from moving upstream.

back to top

Are wildlife impacted by the mine?

The mine area itself is above the tree line in Alpine tundra at an elevation of 1,400 meters. It has minimal soil development due to its recent de-glaciation, so does not host significant animal habitat. The access road to the site traverses lower elevation areas with mature vegetation, and wildlife mitigation measures will be in place along it, as well as management measures such as gated control at Highway 37.

How do you ensure that your contractors at the Brucejack site comply with the same environmental standards as Pretivm?

All contractors working at the Brucejack site must comply with the terms of Pretivm’s Environmental Policy. We maintain Standard Operating Procedures which address the environmental impacts of potentially harmful supplies and their use. Third party audits are conducted for potentially harmful products as well as the use, storage methods and transportation of those products. All non-compliances are reported as part of the regular environmental reporting required by our permits to operate the mine.

What does Pretivm do to address greenhouse gas emissions at the Brucejack Mine?

Total direct greenhouse gas emissions data for Brucejack are reported to Canadian and provincial regulatory agencies as part of our environmental monitoring and reporting program. The emissions are not above the threshold that requires third party verification. We are conscious of the importance of limiting greenhouse gas emissions and incorporated energy efficiency into the design and operation of the Brucejack Mine.

Though it is remote, Brucejack is connected to the BC Hydro transmission grid to access hydro-electric and natural gas power. Other specific efforts to date have included: the use of double chambered incinerators, the use of scrubbers in the mill and assay lab and the initiation of recycling and reuse programs where practical. We reduced power consumption by installing variable frequency drives to increase efficiency in the mill building, and installed a pebble crusher which further grinds ore to increase the efficiency of the ball mill. LED high-bay lighting was installed in the mill building. Additionally, we have a stated “local preference” for sourcing employees, vendors and contractors and services, which also serves to reduce our carbon footprint.

Is there information available on Brucejack’s air emissions?

Quantitative information on Brucejack’s reported air emissions is available through the government’s publicly available National Pollutant Release Inventory.

back to top

How does Pretivm account for the water it uses to operate the Brucejack Mine?

Water use and withdrawal as well as wastewater discharge is monitored and reported to the Canadian and provincial regulatory agencies pursuant to our permit requirements. We recycle treated water through the mill, and all water used is treated and returned back to the environment.

back to top

Does Pretivm have a waste management program?

Pretivm complies with the business waste separation and recycling program in place at its head office in Vancouver. At the Brucejack site, the Waste Management Plan addresses the prevention and minimization of domestic and industrial waste products to the environment. Waste management programs are in place which address waste separation and recycling, as well as industrial, chemical and hazardous waste disposal, pursuant to our operating permits. Our waste facilities are inspected.

What First Nations are in the area of the Brucejack Mine?

The Brucejack Mine access road traverses the asserted traditional territory of the Skii km Lax Ha First Nation, and where it crosses the Bell Irving River near Highway 37 it is located in the asserted territory of the Tahltan First Nation. The Brucejack Mine access road is located in the Naas Area as defined by the Nisga’a Final Agreement.

back to top

Has Pretivm been engaging with the local First Nations and communities?

Pretivm has been providing ongoing project updates to the leaders of several First Nations and northern BC communities in the general vicinity of the Brucejack Mine. Representatives have visited the site, and many individuals have worked at site as Brucejack has evolved from its beginnings as a small exploration project. We will continue to provide project updates on Brucejack as it progresses, and will continue to extend employment opportunities and build commercial relationships in northern BC.

back to top

What are their concerns about a mine at Brucejack?

The high-grade gold underground Brucejack Mine is located in a remote area with a relatively small environmental footprint. One particular issue we have heard raised is how the Mine will contribute to the cumulative impacts of the traffic on Highway 37, as we truck concentrate to the Port of Stewart or to the CN railway near Highway 16. We have advised that our concentrate traffic will comprise up to four to six 40-tonne trucks per day based on our processing rate at a concentration of 10%.

back to top

How will local communities benefit from the Mine?

During construction Brucejack has employed approximately 900 people and, as a 3,800 tonnes-per-day underground mine, will employ approximately 600 - 700 people per year over the life of the mine for an array of technical and non-technical jobs in both surface and underground operations. We are committed to making local employment a priority, and will seek to engage in training partnerships with educational institutions and other organizations. We are also committed to sourcing local contractors and supplies from northern BC where possible.
