  • The Franciscan Friars of Saint Barbara — an charitable religious order whose members take a vow of poverty — received the former Gibson mine site as a donation.
  • But the contaminated site required a costly cleanup, and the friars needed help to turn it from a liability into a sustainable asset.
  • We helped the Friars secure large grants from the U.S. Environmental Protection Agency (EPA) and the Arizona Department of Environmental Quality (ADEQ), as well as in-kind donations, to fund the remediation.
  • We also came up with innovative, cost-saving approaches to waste rock recycling and long-term water treatment at the site.
