South32 outlines innovative water usage and workforce training in Santa Cruz County

The City of Nogales held a regular meeting on September 3, 2025, focusing on significant developments regarding water management, air quality, and workforce training related to local mining operations. The meeting provided updates on ongoing construction projects and community engagement initiatives.

The discussion began with an emphasis on water conservation efforts at the mining site, where construction is currently 40% complete. The mining operation aims to utilize 90% less fresh water than other mines in Arizona, a critical factor given the region's water scarcity. The company has implemented a well protection program, voluntarily monitoring wells within a five-mile radius to ensure that local water supplies remain unaffected by mining activities. This initiative includes commitments to provide alternative water sources for residents should their wells be impacted.

Air quality was another key topic, with the company announcing the deployment of air monitors in the community and along transportation routes. This initiative aims to establish baseline air quality data, addressing community concerns about dust and metal emissions. A public hearing regarding updates to the air permit is scheduled for September 25, where the Arizona Department of Environmental Quality (ADEQ) will clarify misconceptions about the permit status.

The meeting also highlighted workforce development efforts, including a new electrician certification program launched in partnership with the Santa Cruz County provisional community college. The program aims to train local residents, with a commitment that at least 80% of the long-term operational workforce will be from Santa Cruz County. The first cohort of students includes 16 individuals, most of whom are local residents, and the program is designed to enhance skills without requiring repayment or employment commitments.

Construction updates revealed that the project is progressing well, with significant milestones achieved in developing both the zinc processing plant and underground access for manganese exploration. The company anticipates ramping up its workforce significantly over the next 18 months, with plans to hire up to 600 local residents.

In conclusion, the meeting underscored the company's commitment to environmental stewardship and community engagement, while also addressing concerns related to water and air quality. The ongoing training programs and local hiring initiatives reflect a broader strategy to integrate the mining operation into the community positively. The next steps include continued monitoring of environmental impacts and further community outreach to ensure transparency and collaboration.
