DESERT MOUNTAIN ENERGY ANNOUNCES $3.2M NON-DILUTIVE FUNDING AGREEMENT WITH ROSWELL INFORMATION PARK

TSX.V: DME
U.S. OTC: DMEHF
Frankfurt: QM01

VANCOUVER, BC, Sept. 30, 2025 /PRNewswire/ - DESERT MOUNTAIN ENERGY CORP. (the "Company") (TSXV: DME) (U.S. OTC: DMEHF) (Frankfurt: QM01) from the President of the Company. Desert Mountain Energy Corp. is pleased to announce it has signed an agreement with Roswell Information Park LLC to fund key infrastructure associated with previously announced projects on a non-dilutive basis.

The initial funding commitment totals approximately US$3.2 million, with additional contracts to be executed as planning, engineering, and permitting milestones are achieved.

P ipeline and Power Infrastructure

Under the agreement, Roswell Information Park will fund:

• Final engineering, ROW acquisition, and construction of approximately 14 miles of 8-inch pipeline, creating a redundant and secure pathway for locally produced natural gas to reach the "behind-the-meter" power generation site.
• Main pipeline connection costs for long-term natural gas supply.

This infrastructure is designed to support the Park's planned hyperscale AI data center campus, where uninterrupted energy delivery is a critical requirement.

G as Storage and Development

DME has completed a base geologic study identifying a potential formation within its current leasehold capable of serving as an underground natural gas storage unit. Early evaluations indicate capacity of up to 3.0 Bcf, providing redundancy for the Roswell Information Park in the event of scheduled or unscheduled pipeline downtime.

Development plans include:

• All wells drilled will be evaluated for previously non-produced zones possibly containing helium-3, helium-4 and hydrogen.
• Drilling 13 wells to ~3,900 feet, beginning with core sampling for testing and potential conversion into a storage or production well.
• Targeting the Lower Abo Sand Formation for both natural gas and helium potential.
• Construction of a 20-inch pipeline to maintain power supply during critical conditions.
• Geologic engineering.

For hyperscale data centers, dependability is paramount, and downtime is intolerable. Major pipelines across the U.S. often schedule several days of downtime annually, in addition to the risk of unscheduled interruptions. By developing an on-site gas storage unit, DME will provide the redundant energy supply required by hyperscalers to ensure continuous operations.

Advancing Hydrogen and Emissions Solutions

The proposed storage site lies on the western edge of a geologic trend identified by DME as prospective for white hydrogen in shallower formations. Future work will assess integration of hydrogen into the gas stream or conversion into power using advanced hydrogen fuel cells for delivery to the Southwest power grid.

Additionally, DME is collaborating with Roswell Information Park, hyperscale tenants, regulators, and CO₂ end users to incorporate long-term emission control solutions, with associated costs to be borne by the Park.

Strategic Impact

By structuring this agreement as non-dilutive funding, DME secures financial support while preserving shareholder value. The project is expected to generate new revenue streams from:

• Gas storage operations
• Local pipeline management
• Future CO₂ capture and utilization initiatives
• Sales of processed natural gas and helium production

"This agreement represents a critical step forward in building the infrastructure required to support hyperscale data centers in New Mexico," comments CEO Robert Rohlfing. "The funding arrangement ensures Desert Mountain Energy advances its strategic projects without shareholder dilution, while positioning the Company to generate long-term revenue from gas storage, pipeline operations, and future emission solutions."
