Building In Restoration from the Start

From the beginning, the Stibnite Gold Project was designed with environmental restoration in mind. At Perpetua Resources, we know restoring the land and sourcing critical minerals for our country are goals that can exist in harmony. A portion of revenues from mining are designated to pay for restoration, allowing both to move forward together.

the PROBLEM

From Past to Present

Stibnite has a long history of mining stretching back more than a century, much of it predating today’s environmental standards. When early operators stopped mining, they left behind legacy materials and contamination, disrupted ecosystems, and streams and wildlife habitat in need of repair. A modest restoration effort in the 1990s made a start, but the site still needs a more complete, modern approach to restoration – the kind of comprehensive stewardship that the Stibnite Project is designed to deliver.

the Solution

From Impact to Opportunity

The Stibnite Gold Project is designed to address these impacts directly — pairing mining with restoration work that begins early and continues throughout the life of the Project.

The mine plan approved by the U.S. Forest Service includes these features:

Rebuilding the River System

A specially designed fish passage tunnel to reconnect fish to blocked spawning grounds will be constructed before mining begins, and work to restore a natural river channel will occur before mining operations are completed.

Removing and Securing Legacy Waste

Millions of tons of historic mine waste will be reprocessed and stored in a modern, lined facility to improve local water quality conditions and wetlands.
