DSA-25-00179 — Expansion and modernization of mining operations at the Sacaton Mine; reopening and operation of the Sacaton Mine in Casa Grande, AZ

A major general plan amendment seeks to redesignate approximately 1,833 acres from mixed residential and commercial uses to Manufacturing and Industry to permit expansion and modernization of the Sacaton Mine. The project is expected to generate high-paying, skilled jobs for Casa Grande residents and aligns with the city's aggregate resources and industrial development goals, though concerns were raised about a 500-foot buffer distance between mine operations and adjacent residential properties.
