Backgrounders

Project marks the first combined assessment, permitting process under new act
  • The Highland Valley Copper Mine Life Extension (HVC) project is the first reviewed under the Environmental Assessment Act in which applications to the Environmental Assessment Office (EAO) and permitting agencies were combined into a single application.
  • The EAO collaborated with the ministries of Environment and Parks, Mining and Critical Minerals, and Water, Land and Natural Resource Stewardship to streamline the technical review and permitting process for the project to enable permit decisions right away after the assessment certificate decision.
  • The environmental assessment and permitting reviews are usually done sequentially, with permitting taking one to two years to complete after a certificate is issued.
  • This collaboration provides a more comprehensive, timely regulatory process, while ensuring all regulators apply proper due diligence to protect the health and well-being of the environment and communities.

Highland Valley Copper Mine life extension

  • The environmental assessment process for the HVC project began in September 2019 and concluded when the certificate was issued on June 17, 2025.
  • Subject to receiving all required permits, Teck Highland Valley Copper Partnership is now approved to modify the existing mine to continue operations for an additional 18 years. The mine would have reached its production limits in 2028.
  • The project will involve an expansion of the existing open pit, as well as upgrades and modifications to some mine site infrastructure and processing facilities to support the increased production capacity. This will result in 1,526 hectares of new land disturbance.
  • Construction costs are estimated at $1.5 billion, with an additional $690 million in operations over the additional 18 years.

First Nations engagement and dispute resolution

  • The EAO sought consensus at key milestones with 17 potentially affected First Nations.
  • Ministers met with leadership of Stk’emlúpsemc te Secwépemc Nation, Nlaka’pamux Nation Tribal Council, Citxw Nlaka'pamux Assembly and Lower Nicola Indian Band prior to making their decision.
  • Two groups representing six First Nations triggered dispute resolution at the final stage of the assessment.
  • Nlaka’pamux Nation Tribal Council withdrew from dispute resolution after reaching an agreement with the Province outside of the assessment process, which resolved some of their concerns.
  • Following the conclusion of dispute resolution with Stk’emlúpsemc te Secwépemc Nation, the EAO modified some of the conditions recommended to ministers for inclusion in the environmental assessment certificate.
  • Reports from both dispute resolution facilitators were posted to the EAO’s project-information website and provided to ministers to support their decision.
  • Multiple First Nations conducted their own Indigenous-led processes to assess potential effects to Indigenous interests. Their reports were included in the package of information on the assessment provided to ministers.
  • Key issues raised by First Nations included:
  • historical effects of mining on land, water, air, animals and plants and cumulative effects with forestry and other industrial development in the area;
  • limited ability for First Nations to exercise Aboriginal rights, including for harvesting and cultural and spiritual practices; and
  • water scarcity in the region, existing water quality issues and additional effects from continued mining.
  • Several First Nation also acknowledged economic benefits from the mine; however, others did not perceive the benefits to outweigh the risks.

Community collaboration:

  • The EAO sought extensive public feedback throughout its review, with about 40 comments received from members of the public during three public comment periods. Comments and concerns were incorporated into the final assessment report.
  • The technical advisory committee for the project’s assessment included representatives from the District of Logan Lake, Village of Ashcroft, and Thompson-Nicola Regional District, as well as technical experts and First Nations and B.C. government representatives.

Compliance  and enforcement:

  • Teck is required to comply with 17 legally enforceable requirements established as a condition of receiving the environmental assessment certificate, and to build and operate the project in accordance with the certified project description.
  • EAO compliance and enforcement officers monitor compliance with environmental assessment certificate requirements in co-ordination with other regulatory agencies.
  • Monitoring and inspection of the project will begin with the start of construction.
