NG ENERGY ANNOUNCES SPUDDING OF ARUCHARA-4 AT MARIA CONCHITA AND PROVIDES SINU-9 PRODUCTION UPDATE

CALGARY, AB, August 14, 2025 – NG Energy International Corp. (“NGE” or the “Company”) (TSXV: GASX) (OTCQX: GASXF) is pleased to announce the spudding of the Aruchara-4 well at Maria Conchita and that aggregate gross production from Sinu-9 has reached 22 MMcf/d.  The Company is also pleased to provide an operational update for both Maria Conchita and Sinu-9. 

Maria Conchita

At Maria Conchita, the Company has commenced drilling of the Aruchara-4 well, which targets the Jimol formation and aims to develop the H1A and H1B accumulations while exploring the potential extension of reserves and resources in the H2 AA section and H3 and H4 fractures, as well as testing the limestone formation on top of the basement of the well. The Aruchara-4 well will be drilled to a total depth of 10,000 feet in four phases and upon successful completion, is expected to be tied in by the end of September 2025.

Following the drilling of the Aruchara-4 well, the rig will immediately commence a workover and recompletion of the Aruchara-3 well to address a downhole mechanical obstruction, restoring it to full production capacity, before moving to commence drilling of the Aruchara-5 well. 

Sinu-9

At Sinu-9, the Company is pleased to announce that production has increased to 22 MMcf/d while meeting the Unified Transportation Regulation’s dew point quality standards. Installation of dew point handling equipment at the Central Processing Facility is nearing completion, with full installation expected by the end of August. Following installation of the dew point handling equipment, aggregate gross production at Sinu-9 is expected to increase up to 30 MMcf/d, filling current pipeline capacity. 

As announced in the Company’s June 23, 2025, news release, construction is underway on a twin pipeline with the Company’s infrastructure partner INFRAES, which will double transportation capacity from Sinu-9. This project is being completed in two phases: (1) an 18-kilometer loop from Jobo along the existing right-of-way, which will increase transportation capacity at Sinu-9 to 40 – 45 MMcf/d; and (2)  the full twin pipeline, which will increase transportation capacity at Sinu-9 to 60 MMcf/d and is expected to be completed in Q1 2026.

Information Regarding the Company’s Working Interest Disclosure

With regard to the Company’s working interests held in both the Maria Conchita and Sinu-9 Blocks, in both the context of this news release and the Company’s previous news releases, the term “working interest”, ultimately refers to the rights and obligations agreed to, eventually, materialize a contractual interest in an exploration and production contract before the ANH, subject to the fulfillment of certain conditions. These conditions involve the assumption of financial risks and are generally linked to exploration by virtue of joint operating agreements. Once such conditions are fulfilled, the acquisition of a registered contractual interest, as party of record, in the exploration and production contract may materialize, by way of a request for approval of assignment before the ANH. For this reason, as is common practice within the oil and natural gas industry as a whole, the disclosed “working interest” may not coincide with the Company’s current contractual interest in the exploration and production contract. 

The assignment and allocation of “working interests” does not affect or undermine, in any way, the rights and obligations of registered parties under the relevant exploration and production contracts. Registered parties remain wholly and totally liable before the ANH, the Colombian authorities and third parties in connection with any and all obligations, risks and liabilities derived from the execution, performance or termination of the exploration and production contracts. Conversely, the rights and obligations that comprise “working interests” are only enforceable vis a vis between the executing parties under private agreements, and have no legal effects before the ANH, the Colombian authorities or third parties.

As of the date hereof, the Company is a party of record and holds a 51% contractual interest in the exploration and production contract for the Sinu-9 Block granted by and entered into with ANH. However, under the private agreements regarding the working interests in the Sinu-9 Block, the Company holds a 72% working interest. This means a 21% working interest is yet to be assigned and acknowledged as a contractual interest in the exploration and production contract, given the conditions to do so, including ANH approval, are yet to be fulfilled.  Once these conditions are met, the Company will submit an approval request with ANH. 

As disclosed in the Company’s news release dated February 10, 2025, the Company has agreed to sell a 40% contractual interest in the exploration and production contract for the Sinu-9 Block to Etablissements Maurel & Prom S.A., effective as of February 1, 2025. Additionally, Clean Energy Resources S.A.S. remains the operator of record under such exploration and production contract and before the ANH.

With respect to the Maria Conchita Block, the Company holds 100% of the contractual interest as the sole party and operator of record under the relevant exploration and production contract entered into with the ANH, and holds an 80% working interest under private agreements with third parties.
