Black Butte Copper Project

Sandfire holds an 87% interest, via Canadian listed company Sandfire Resources America Inc. (TSX-V: SFR), in the high-grade Black Butte Copper Project, located in central Montana in the United States.



The Black Butte Copper Project is one of the world’s highest-grade undeveloped copper projects. The planned mine development will utilise best-practice technology and modern mining techniques to develop a wholly underground mine with minimal surface footprint and environmental impact.

The project is located on private ranch land in Meagher County owned by the Group’s subsidiary, Tintina Montana Inc. The site is close to existing road, power and rail infrastructure, with the ability to access a residential workforce located nearby and competitive sources of materials and power.

The proposed underground mine at Black Butte is designed to provide economic opportunity to Central Montana while fully protecting the Smith River Watershed.

Project permitting for Black Butte was completed in April 2020, with the Montana Department of Environmental Quality (MTDEQ) releasing the Final Environmental Impact Statement (EIS) on 13 March 2020 and issuing a positive Record of Decision (ROD) to grant a Mine Operating Permit (MOP) on 9 April 2020.

Sustainability Snapshot – Water at Black Butte 

Sandfire America is committed to protecting the water resources in the water catchment area. Careful management is critical to maintaining water quality and quantity. To protect the water quality and quantity, the proposed underground mine is designed with:

  • All planned openings or entry points to the mine (including air ventilation and escape routes) are located far above the water table to keep water from leaving the mine after closure and mixing with surface water.
  • All ground water from the mine and surface run off water from precipitation will be collected, monitored, tested, and treated before being placed back into the ground water system through an underground infiltration system buried 2 metres below the surface. There is zero discharge to surface waters. Water temperature will also be monitored and maintained through this system.
  • A Reverse Osmosis (RO) water treatment plant will be constructed onsite for treating all waters discharged to the underground infiltration gallery and will remain operational through the reclamation phase of the mining operation.

    Sandfire America continues to work closely with the local community and Government agencies to ensure our water management practices are sustainable.
