Vancouver, Canada – TheNewswire - May 5, 2026 — DESERT MOUNTAIN ENERGY CORP. (the “Company”) (TSX.V: DME, U.S. OTC: DMEHF, Frankfurt: QM01) is advancing plans to reconfigure its Pecos Slope gas gathering system. As previously announced, the Company is raising capital to maximize natural gas sales and provide additional operational options with its helium plant. This work includes the replacement of many miles of existing, inefficient and aging gathering system lines, some of which are in excess of 45 years old and require increased maintenance.

The planned reconfiguration is expected to both reduce long-term operating costs and increase overall gas sales. The Company has many miles of existing Right of Ways (ROW’s) and is in the process of acquiring replacement gas lines and securing additional ROW’s, as needed, as the work progresses.

With respect to litigation initiated by the City of Flagstaff against DME, the Arizona Court of Appeals ruled in DME’s favor on a petition for special action and ordered that judgment be entered in DME’s favor on all claims brought by the City. The City subsequently filed a new lawsuit against DME, which DME has removed to Federal Court. DME will continue to vigorously defend against the City’s unfounded claims in any forum in which they are brought.

The Company continues to await a decision from the Arizona Department of Environmental Quality (AZDEQ) regarding its requests related to previously drilled wells in the field south of Winslow, Arizona. The Company continues to maintain its solar facilities located in the area.

In addition to the formation of Helios Data Company for its digital assets, the Company has formed a U.S.-based corporation in Wyoming to address future carbon capture initiatives. The new subsidiary, DME Carbon Cap LLC., is majority-owned by the Company. This entity is intended to support the Company’s future plans to provide its technology and plant design to third parties in the United States and internationally, as well as to support a potential uplisting to a senior U.S. exchange.

Desert Energy UK Ltd. has received significant gas and soil analysis, along with geological data, from independent third parties. The Company is currently working with two potential partners in connection with confirmation gas and soil analysis and the potential acquisition of seismic data based on those results. In light of these developments, Mr. Orr and DME have mutually agreed to his resignation as COO effective 5/05/26, so that Mr. Orr can focus his efforts on DME’s subsidiary development opportunities in the UK and the United States.
