Vancouver, British Columbia--(Newsfile Corp. - June 18, 2026) - Altura Energy Corp. (TSXV: ALTU) (OTCQB: ALTUF) (FSE: Y020) ("Altura" or the "Company") is pleased to announce that it has returned the two wells worked over to date, PSOC 23-15 and PSOC 22-8, to production following work completed during the Company's 2025 field program. The flow rates are improving daily and final rates will be announced once wells have stabilized. In addition, Altura has completed cased hole log analysis on three previously drilled wells.

The analysis identified additional potential within the Shinarump formation, increasing the number of prospective workover candidates from six to seven wells. To advance the next phase of field activity, a workover rig arrived on site on June 11 th and has commenced workovers on the remaining five prospective wells in Saddle Horse Draw. "The successful return of production is only the first step in unlocking long-term value from the Pinta South Helium Field," said Ashley Lastinger, CEO of Altura.

"With the log analysis having identified a seventh workover target and the rig on site, we are well positioned to accelerate helium production growth and field development." All seven wells in the Saddle Horse Draw area are tied into the on-site helium processing facility by the eight-mile pipeline recently completed by the Company. Any helium produced from these wells will be sold through a long-term offtake agreement. ABOUT ALTURA ENERGY CORP.
