While the relationship between EnviroMINE, Inc. and Project Cornerstone, Inc. is close, the two entities' missions and objectives are very different.  Project Cornerstone rents office space and shares staff with EnviroMINE; however, the two organizations' activities are conducted completely separate from one another.  Project Cornerstone's activities are focused on the education of the construction aggregates industry, as a whole, throughout all of San Diego County, and does not represent specific projects in the permitting process.
