Desert Mountain Energy signs long-term Roswell Information Park lease

  Vancouver, Canada – TheNewswire - May 29, 2026 — DESERT MOUNTAIN ENERGY CORP. (the “Company”) (TSX.V: DME, U.S. OTC: DMEHF, Frankfurt: QM01) is pleased to announce that it has entered into a 25-year lease agreement with Roswell Information Park LLC (RIP) for a proposed off-grid data center. The agreement further provides for an additional five-year term. The project will be located on property previously purchased by the Company.

The approximately 154-acre site near Roswell, New Mexico, is intended for a multi-use development. The property does not include mineral, oil, or gas rights; however, limited water rights are included. The agreement also addresses two previously signed contracts with RIP.

One agreement related to natural gas purchasing and the other to the construction of a gas transportation line. As the selected location is not within the same section, township and range previously planned by the developer, it was agreed that DME will be responsible for developing a new route, determining an appropriate price adjustment for missed payments (please see news releases dated July 2, 2025 and   September 30, 2025 )  and additional pipeline length. A separate long-term gas supply contract is expected to be executed prior to construction and will reflect the forecast long-term demand for natural gas.

The agreement to lease the majority of the property to RIP includes modest monthly lease payments. In addition, DME will receive a 5% management fee on all natural gas used by the facility for the operational lifetime of the project. This fee is irrespective of which entity or entities produce or transport the gas.

The agreement also provides for a 2% management fee payable to DME on any excess electricity generated by the operators of the data center and returned to the power grid for the lifetime of the information park. The agreement further includes significant penalty payments payable to DME should the tenant withdraw at any time within the first 24 months. RIP can exercise an option to purchase if a bonus payment is made by a preset date, for a to-be-determined price not to exceed 4X DME’s purchase price for the property.

All management and override fees continue for 25 to a maximum of 30 years. RIP continues to work closely with DME in its efforts to identify a potential pathway for the utilization of water produced by other participants in the energy sector. These efforts include the application of newer technologies for produced water treatment, coupled with on-site power generation, with the goal of reducing the burden of large-scale infrastructure costs typically associated with data center developments on the local community.

RIP is also refining its “closed loop” operational design to further mitigate community concerns. The agreement further carves out 14 acres for DME to utilize for a potential NaCL or Na-ion based battery plant. RIP also reserves the right to be one of the first customers for those batteries for use in the information center’s redundant power supply systems.
