Environmental Remediation

Seabridge Gold is committed to reclaiming the historic legacy and outstanding liabilities at the former Johnny Mountain Mine (JMM) site with the support of the Tahltan Nation following the approved Closure and Reclamation Plan. The historic infrastructure which remained at JMM when it was acquired by Seabridge Gold included a 350 tonne per-day processing plant, fuel tank farm, an airstrip, 3.5 kilometres of underground workings, an 11.5 hectares tailings impoundment facility, waste rock dumps, multiple unauthorized landfills and various old equipment.

In 2017, Seabridge Gold started implementing the multi-year and multi-million dollar reclamation program for JMM in partnership with the Tahltan Central Government (TCG) and the Tahltan Nation Development Corporation (TNDC). The complete reclamation and closure of the JMM Site is anticipated in 2025.

In 2022, Seabridge Gold was recognized with the prestigious Jake McDonald Annual Mine Reclamation Award for voluntarily reclaiming the Johnny Mountain Mine site. The award is presented annually by the British Columbia Technical and Research Committee on Reclamation (TRCR) to recognize outstanding achievement in mine reclamation in British Columbia.

To date, Seabridge Gold has invested more than $8 million to ensure that the Iskut Project is in compliance with BC Government regulations and authorizations and on restoring the Johnny Mountain Mine site.

The overall objective of the reclamation plan for Johnny Mountain site is to return disturbed lands and new anthropogenic landforms to their original land use and capability of alpine tundra wildlife habitat. Some of the remediation work completed so far includes:
