Desert Mountain Energy Applauds EPA Administrator Lee Zeldin's Approval of Arizona's UIC Primacy Request

Desert Mountain Energy Corp. (TSXV: DME) (OTC: DMEHF) (Frankfurt: QM01) proudly joined leaders from across Arizona last week as U.S. Environmental Protection Agency (EPA) Administrator Lee Zeldin formally approved the State of Arizona's application for primacy to oversee permitting and regulatory responsibilities for all underground injection wells under the Safe Drinking Water Act (SDWA).

This landmark decision marks a major milestone for Arizona's energy sector, empowering the state to directly regulate underground injection wells used in oil, gas, and helium production. Desert Mountain Energy was honored to be invited to Washington, D.C., to witness this significant moment for Arizona's energy and environmental future.

Desert Mountain Energy was present at the signing ceremony and commends Administrator Zeldin for his leadership in advancing regulatory efficiency and supporting energy innovation in the western United States.

Robert Rohlfing, CEO of Desert Mountain Energy, said: "We are incredibly grateful to Administrator Zeldin for his thoughtful work and steadfast partnership with Arizona. The approval of primacy is not only a victory for our state's sovereignty, but a key step in promoting responsible development of Arizona's vast natural resources."

Desert Mountain Energy also extends its sincere thanks to Congressman Juan Ciscomani, Congressman Andy Biggs, and Congressman Paul Gosar for their tireless advocacy on behalf of Arizona. Their commitment to advancing common-sense regulatory reforms has played a vital role in securing this achievement.

With the state now in control of the permitting and oversight process for the UIC program, Desert Mountain Energy is optimistic about the future of domestic energy and helium production in Arizona, where the company continues to lead in sustainable resource development.
