PROJECT OVERVIEW

The Cactus Mine (formerly the Sacaton Mine) is located in Arizona at the convergence of three major geologic zones in western Pinal County, just west of Casa Grande. It was discovered in 1961 by American Smelting and Refining Co. (ASARCO) which mined the site from 1972 to 1984. During its previous operation, the mine extracted 38 million tons, with 400 million pounds of copper, 759,000 ounces of silver, and 27,000 ounces of gold from the West open pit orebody.

In 1982, construction began on the production shaft to a depth of 1,800 ft and a headframe to the southwest of the pit to access the higher-grade ore via underground mining methods; however, development was suspended due to market conditions and in 1984.

In 2009, the site was placed into the care of an environmental trust that was tasked with the care, stabilization, and reclamation of the site. This work was done under the supervision of the Arizona Department of Environmental Quality (ADEQ) and the US Environmental Protection Agency. 

In July 2020, the company now called Arizona Sonoran Copper (ASCU) completed the purchase of the site from the trust, taking custody of the property. As a result, ASCU will be starting its work with a remediated former mine site, with an environmental baseline study completed which has been approved by the ADEQ.

A detailed environmental plan will be drafted up as the company progresses and conducts additional studies on the property.

In 2009, the site was placed into the care of an environmental trust that was tasked with the care, stabilization, and reclamation of the site. During that time extensive environmental characterization and cleanup work was completed under the supervision of the Arizona Department of Environmental Quality (ADEQ) and the US Environmental Protection Agency. In order to inform the remediation process, environmental studies, groundwater characterization, stormwater evaluation, geochemical, geotechnical and vegetation assessments and impacted soil investigation studies were completed.

In all, $20 million was invested to reclaim the property and historic buildings/structures, including the tailings facility (covered and revegetated), mine buildings and mine infrastructure (demolished) and complete certain environmental analyses to ensure it’s work is complete. 

In July 2020, Elim Mining completed the purchase of the site from the trust, taking custody of the property. As a result, Elim will be starting its work with a remediated former mine site, with an environmental baseline study completed which has been approved by the ADEQ.

A detailed environmental plan will be drafted up as the company progresses and conducts additional studies on the property. For example, rather than cover and revegetate the stockpile, Elim has a unique opportunity to move the unlined stockpile to a new fully lined and environmentally friendlier location and process the ore along the way. Moving the stockpile will significantly reduce the current footprint 5,000 feet wide by 5,000 ft long by 100 ft high stockpile and improve the safety of the land. In addition, it allows future operations to be further contained on the current mine footprint.

JOBS

ASCU is committed to hiring and retaining talent from the region. This work will continue and evolve over the life of our project and we will continue to look for ways that we can benefit regional educational resources from kindergarten through advanced degrees.

OUR CORE VALUES

To us, this is a journey of renewal. We are committed to mining sustainably as we revitalize a previously abandoned site. During this we will contribute to local economic development in our new home in Pinal County, and power a renewable energy future.

CORE VALUE: RESPONSIBLE OPERATIONS AND CAREFUL STEWARDSHIP OF THE ENVIRONMENT

We operate in an environmentally responsible manner, investing in low carbon and water-efficient technologies.

WATER

In the desert Southwest, every drop of water counts. During the process of revitalizing this previously mined site, careful and efficient stewardship of water is at our core. In keeping with this, we will look for creative and adaptive ways to better our site will be a zero-discharge facility. This means that wastewater will be treated and used again and again in the process.

ENVIRONMENT

We care about the community and the issues that are important to the region. We are committed to fully understanding the impact of our operations and how to address our role within the community. We look to be careful stewards of water and minimizing dust while bringing jobs and economic activity to the community.  The revitalization of this previously abandoned mine will allows us the opportunity to mine with the following objectives:

  • Reduced carbon footprint
  • Proactive air quality management
  • Concurrent reclamation
  • Restoration of habitat
  • Management of waste
  • Planning for responsible closure

Our team is dedicated to operating a responsible and respectable mine site. We look to meet all applicable requirements under the Clean Water Act (CWA), Clean Air Act (CAA) and all other applicable federal rules and regulations. 

CORE VALUE: A RENEWABLE ENERGY FUTURE

The future of the US’s role in shifting to green technology is dependent on the production and supply of copper. The copper we will produce is a critical component in producing renewable energy, electric vehicles, and much more. With Pinal County as a future hub for electric car and truck manufacturing, solar facilities and more, we are proud to know that we can be an important contributor to the production of the copper needed to drive the future of the new and green economy.

CORE VALUE: PART OF THE COMMUNITY

We are committed to being part of the community. This goes beyond supporting local economic development and maintaining open dialog with all stakeholders. You will see this in our respect of local culture and traditions, sourcing locally, hiring locally, and in our support of programs that improve the quality of life in the region.
