Blue Mountain Minerals is largely owned by its employees. Most of them live right here in Tuolumne County and, over the years, they, along with the company, have donated many thousands of dollars in cash and materials to community organizations and projects.

We are active in the community, volunteering countless hours to our local schools, business, civic and charitable groups, youth activities, churches and community projects, helping to make life better in Tuolumne County:

 • Columbia Elementary School

 • The Community Challenge Campaign
    for our Seniors

 • Tuolumne County Alliance for Resources
    & Environment (TuCARE) Tours for Kids
