Exhibit 99.1

Okmin Resources to Increase its Stake in the Pushmataha Gas Field and to exit the Blackrock Joint Venture

Encino, California – August 21, 2025 – Okmin Resources, Inc. ("Okmin" or the "Company") (OTCQB: OKMN) today announced it has entered into an agreement with Blackrock Energy, LLC to exchange its 50% working interest in the oil and gas leases known as the Blackrock Joint Venture for $25,000 cash and an additional 45% interest in the Pushmataha Gas Field. The additional interest in Pushmataha will increase Okmin’s ownership of the project from 50% to 95%.

The Blackrock Joint Venture encompasses 15 oil and gas leases located in Okmulgee and Muskogee Counties, Oklahoma. The Company’s decision to divest its interest in this project aligns with its ongoing strategy to streamline operations and focus on assets with stronger growth potential.

The Pushmataha Gas Field consists of six leases covering approximately 3,840 acres in Pushmataha County, Oklahoma. The leases, held via an interest in a joint venture, carry net revenue interests ranging from 68% to 76%. There are currently seven gas wells on the property, with depths ranging from 10,000 to 12,300 feet. In 2022, Okmin conducted a hydrocarbon survey across the Pushmataha leases using a third-party, patented remote sensing technology. This survey provided valuable subsurface data and confirmed there is significant potential to drill new wells as much of the property is currently undeveloped. The existing seven wells also show additional behind-pipe natural gas zones. With the commitment of new capital or with an outside farm-in partner, the operator believes the existing wells can be reworked and recompleted to optimize their production in addition to the potential for drilling new wells to further develop this property.

“This transaction reflects our ongoing review and optimization of the Company’s asset portfolio,” said Jonathan Herzog, Chief Executive Officer of Okmin Resources. “Although we put considerable effort into the Blackrock project, persistent infrastructure issues, nearly stagnant oil prices, and increasing operating costs have prompted us to shift our focus. By significantly increasing our stake in the Pushmataha project, we are positioning the Company to meaningfully capitalize on a greater-potential asset.”
