San Joaquin River Threatened by 600-Foot-Deep Blast Mine
The San Joaquin River, the primary water source for over 30 million Californians and nearly half of California’s $61 billion agricultural economy, is currently threatened by a proposed blast mine dangerously near communities.
CEMEX, a gravel mining and cement producing company, is pursuing a 100-year permit for the creation of a 600-foot-deep blast mine along the San Joaquin River, just outside of the city of Fresno, adjacent to Lost Lake County Park and the San Joaquin River Parkway. This project would threaten drinking water quality for the surrounding region, ecosystems in the immediate vicinity of the mine and far downstream, and several nearby endangered species. If approved, this project would stall completion of the restored San Joaquin River Parkway by 100 years.
Tell the Fresno County Board of Supervisors to reject CEMEX’s proposal to expand their operating permit to create a 600-foot-deep blast mine.

The final public comment period for the site’s approval will open in Spring 2026 following the release of the Final Environmental Impact Report (FEIR), marking a critical opportunity for public input. Community members do not need to wait. American Rivers and our partners are urging communities to share their opposition to the project now.
