WATER AND ENVIRONMENT
– Doing It Right. Right from the Start

For many residents, water and land protection are the first questions — and they should be. This page explains how modern projects are planned to protect groundwater, manage water responsibly, monitor performance, and plan for long-term land stewardship and reclamation.

Our goal is to balance the need for natural resources with the responsibility to protect communities and the environment. By using improved technology, careful planning, and open communication with the community, we can work protect water and environment. At the same time, ensure that the benefits of copper production—such as jobs, economic growth, and materials needed for modern technology—are shared with local communities and future generations.

“By implementing the dry stack tailings process Copper Flat’s water will allow a reduction in water use of up to 90%. That saves 1.6 billion gallons annually, enough to supply all Sierra County households with 3X more than their typical yearly water needs.”

— Stephen Crosby, Copper Flat Project Manager

Water Quality and Water Use

Copper Flat will use dry stack tailings technology and AI-driven water treatment and filtration system to achieve zero process water discharge and water use reductions:

  • More than 90% of processing water will be recycled for re-use
  • Elimination of open water ponds reduces seepage risk to surface water by 90-100%
  • 77% freshwater usage reduction
  • 80% demand reduction in groundwater

Dry Stack Tailings Process. Unlike traditional tailings storage that rely on large dams and water-filled impoundments, dry stack tailings are dewatered through pressure or vacuum filtration. Most of the water is recovered and recycled back to the processing plant, greatly reducing the mine’s freshwater needs. The resulting dry, compacted material is stacked, which improves stability and minimize dust generation.

Artificial Intelligence-driven water management optimizes efficiency and sustainability by using predictive modeling, intelligent sensors, and automation to monitor water quality and reduce waste in real-time. AI minimizes water usage, improves recirculation, detects leaks, and enhances treatment efficiency.

Reclamation of Land

One of the key aspects to the Copper Flat Project is the progressive revitalization of disturbed land, decommissioning infrastructure, and restoring ecosystems throughout the entire life cycle of the mine:

  • 30–50% faster closure.
  • Self-generated cover material

This approach reduces environmental risks and ensures faster, more successful final restoration of the copper mine and surrounding eco-systems. Key actions include stabilizing landforms, progressive revegetation, and integrating closure planning into daily operations to achieve a sustainable post-mining land use.

Dust, Air Quality, Noise and Traffic

New dust control technologies and constant air quality monitoring to make the environment safer for people and animals.

  • 25-92% reduction in emissions

Today, new dust control technologies reduce these problems. From spraying water on roads and work areas and covering trucks to monitoring air quality regularly, we will help keep the air cleaner and make the surrounding environment safer for both people and animals.

Copper Flat plans on the use of more electric-driven equipment and truck routes that avoid busy residential areas whenever possible. By working closely with local governments and residents, we can help reduce disruptions to everyday life.

Frequently Asked Community Questions

Protecting water quality is a central priority for the Copper Flat Project. The mine will use dry stack tailings technology and AI-driven water treatment and filtration systems designed to prevent contamination and reduce water use. More than 90% of processing water will be recycled, eliminating the need for large water-filled tailings ponds and helping ensure zero process water discharge from the operation.

Dry stack tailings are created by removing most of the water from the mining by-products using pressure or vacuum filtration. The remaining material becomes a dry, compacted solid that can be safely stacked rather than stored behind large dams.

This method:

  • Recovers and recycles most of the water back into the processing plan
  • Reduces the need for freshwater
  • Improves stability compared to traditional tailings dams
  • Minimizes dust and environmental risks

The Copper Flat Project is designed to significantly reduce water demand compared to traditional mining operations. The system aims to achieve:

  • More than 90% recycling of processing water
  • 77% reduction in freshwater use
  • 80% reduction in groundwater demand

These improvements come from efficient filtration, water recirculation, and advanced monitoring systems.

Artificial intelligence (AI) will help monitor and manage water systems across the site in real time. Using predictive modeling, intelligent sensors, and automated controls, AI can:

  • Track water quality continuously
  • Detect leaks quickly
  • Optimize water recycling
  • Improve treatment efficiency

This technology helps reduce waste and ensures water resources are used as responsibly as possible.

Land restoration is planned from the very beginning of the project. The mine will follow a progressive reclamation approach, meaning restoration begins while mining is still underway rather than waiting until the end.

This includes:

  • Stabilizing landforms
  • Re-vegetating disturbed areas
  • Decommissioning infrastructure when no longer needed
  • Using self-generated cover material

This approach can lead to 30–50% faster site closure and more successful long-term ecosystem recovery.

Modern dust control technologies will be used to keep the surrounding air cleaner and safer for people and wildlife. Measures include:

  • Spraying water on roads and work areas
  • Covering trucks transporting materials
  • Continuous air quality monitoring

These measures are expected to achieve 25–92% reductions in emissions, depending on operating conditions.

Some increase in activity is expected, but the project is designed to minimize disruption. Plans include:

  • Using more electric-powered equipment, which operates more quietly
  • Truck routes that avoid residential areas whenever possible
  • Coordinating with local governments and community members to reduce impacts

The Copper Flat Project aims to balance the need for copper—an essential material for modern technology and clean energy—with responsible environmental practices. By using advanced technology, careful planning, and ongoing community communication, the project seeks to protect water, land, and air while supporting local jobs, economic growth, and long-term sustainability.
