EnviroMINE supports organizations who conduct outreach programs that educate the community about the importance of local construction aggregates, and those who advocate for the mining industry. 

San Diego County’s aggregate shortage problem is very simple; demand is steadily increasing while permitted aggregate supplies within the county are steadily decreasing.  Currently, the county imports 50% of aggregate to satisfy demand.  Local supplies are decreasing as a result of fewer quarries in the county.

These organizations support the aggregates industry through educational and awareness programs.

Project Cornerstone’s mission is to educate the public about the importance of local construction aggregates (i.e., sand, gravel and crushed stone) through hands-on learning in Science, Technology, Engineering and Mathematics (STEM).  Construction aggregates are used to build roads, houses, schools and all other infrastructure; they are the cornerstone of our communities.

The organization's goals are to:

  • Inform the public that using locally sourced minerals has environmental and economic benefits.

  • Educate students how construction aggregate is produced and where it is used in their everyday lives.

  • Promote the use of local resources to satisfy projected demand.

  • Endorse the conservation of classified and designated mineral resources for future development.
