Information Regarding the Preparation of Reserves and Resource Information

Sproule International Limited ("Sproule"), an independent qualified reserves and resources evaluator, has conducted the reserves and resource evaluation for Maria Conchita and Sinú-9 in accordance with the Canadian Oil and Gas Evaluation Handbook (the "COGE Handbook"). It adheres in all material aspects to the principles and definitions established by the Calgary Chapter of the Society of Petroleum Evaluation Engineers regarding annual reserve and resource reports that are being released in the public domain. The COGE Handbook is incorporated by reference in National Instrument 51-101 - Standards of Disclosure for Oil and Gas Activities.

The Company's Form 51-101F1 – Statement of Reserves Data and Other Oil and Gas Information for the fiscal year ended December 31, 2023, prepared by Sproule in accordance with the COGE Handbook and has an effective date of December 31, 2023 (the "2023 51-101F1") was filed on SEDAR+ on April 26, 2024. As per the requirements of Form 51-101F1, since Maria Conchita and Sinú-9 are both located in Colombia, the Company has disclosed its reserves in the 2023 51-101F1 on an aggregated basis. The reserves in the 2023 51-101F1, which are attributed to Sinú-9 are based on the Sinú-9 Report (as defined below) and the reserves in the 2023 51-101F1, which are attributed to Maria Conchita are based on the Maria Conchita Report (as defined below). The Company uses natural gas liquids and conventional natural gas as the two product types to report the Company's reserves.

The report entitled "Evaluation of the P&NG Reserves and Resources of NG Energy International in the Sinú-9 Block, Colombia" (the "Sinú-9 Report") was prepared by Sproule with an effective date of December 31, 2023 and a preparation date of December 21, 2023. Sinú-9 is located in the Department of Córdoba, Colombia. The Company's working interest in Sinú-9 is 72%, subject to payment of ANH sliding scale royalties. Reserves and resources attributed to the Hechizo, Brujo, Magico, Mago, Hechicero, Encanto, Milagroso, Porquero, Embrujo, Ensalmo and Sortilegio zones have been included in the Sinú-9 Report.

The report entitled "Evaluation of the P&NG Reserves and Resources of NG Energy International in the Maria Conchita Block, Colombia" (the "Maria Conchita Report") was prepared by Sproule with an effective date of December 31, 2023 and a preparation date of December 20, 2023. The Company holds an 80% working interest in Maria Conchita, which is located in the Department of La Guajira, Colombia. Reserves and resources attributed to the H1, H1A, H1A1, H1B, H2, H2B, H3, H4 and LM2 zones have been included in the Maria Conchita Report.

For additional information regarding the Sinú-9 Report, the Maria Conchita Report and the reserves information contained in this news release please see the 2023 51-101F1 filed on SEDAR+ on April 26, 2024, and the Company's news release dated December 27, 2023 entitled "NG Energy Announces 551% YOY Increase to 3P Reserves".

Caution Respecting Reserves Information

The determination of oil and natural gas reserves involves the preparation of estimates that have an inherent degree of associated uncertainty. Categories of Proved, Probable and Possible reserves have been established to reflect the level of these uncertainties and to provide an indication of the probability of recovery. The estimation and classification of reserves requires the application of professional judgement combined with geological and engineering knowledge to assess whether or not specific reserves classification criteria have been satisfied. Knowledge of concepts including uncertainty and risk, probability and statistics, and deterministic and probabilistic estimation methods is required to properly use and apply reserves definitions.

The recovery and reserve estimates of natural gas liquids and natural gas reserves provided herein are estimates only. Actual reserves may be greater than or less than the estimates provided herein. The estimated future net revenue from the production of the disclosed natural gas reserves does not represent the fair market value of these reserves.

Information Regarding Reserves

Reserves are estimated remaining quantities of commercially recoverable oil, natural gas and related substances anticipated to be recoverable from known accumulations, as of a given date, based on the analysis of drilling, geological, geophysical and engineering data; the use of established technology; and specified economic conditions, which are generally accepted as being reasonable. Reserves are further classified according to the level of certainty associated with the estimates and may be subclassified based on development and production status.

"Proved reserves" are those reserves that can be estimated with a high degree of certainty to be recoverable. It is likely that the actual remaining quantities recovered will exceed the estimated Proved reserves.

"Probable reserves" are those additional reserves that are less certain to be recovered than Proved reserves. It is equally likely that the actual remaining quantities recovered will be greater or less than the sum of the estimated Proved plus Probable reserves.

"Possible reserves" are those additional reserves that are less certain to be recovered than Probable reserves. It is unlikely that the actual remaining quantities recovered will exceed the sum of the estimated Proved plus Probable plus Possible reserves. There is a 10% probability that the quantities actually recovered will equal or exceed the sum of Proved plus Probable plus Possible reserves.

The qualitative certainty levels referred to in the definitions above are applicable to "individual reserves entities" (which refers to the lowest level at which reserves calculations are performed) and to "reported reserves" (which refers to the highest-level sum of individual entity estimates for which reserves estimates are presented). Reported reserves should target the following levels of certainty under a specific set of economic conditions:

• at least a 90% probability that the quantities actually recovered will equal or exceed the estimated Proved reserves; and
• at least a 50% probability that the quantities actually recovered will equal or exceed the sum of estimated Proved plus Probable reserves.

A qualitative measure of the certainty levels pertaining to estimates prepared for the various reserves categories is desirable to provide a clearer understanding of the associated risks and uncertainties. However, the majority of reserves estimates will be prepared using deterministic methods that do not provide a mathematically derived quantitative measure of probability. In principle, there should be no difference between estimates prepared using probabilistic or deterministic methods.

Each of the reserve categories (Proved and Probable) may be divided into developed and undeveloped categories as follows:

"Developed Producing reserves" are those reserves that are expected to be recovered from completion intervals open at the time of the estimate. These reserves may be currently producing or, if shut-in, they must have previously been on production, and the date of resumption of production must be known with reasonable certainty.

"Developed Non-Producing reserves" are those reserves that either have not been on production, or have previously been on production, but are shut-in, and the date of resumption of production is unknown.

"Undeveloped reserves" are those reserves expected to be recovered from known accumulations where a significant expenditure (e.g., when compared to the cost of drilling a well) is required to render them capable of production. They must fully meet the requirements of the reserves classification (Proved, Probable and Possible) to which they are assigned and expected to be developed within a limited time.

In multi-well pools it may be appropriate to allocate total pool reserves between the developed and undeveloped subclasses or to subdivide the developed reserves for the pool between developed producing and developed nonproducing. This allocation should be based on the estimator's assessment as to the reserves that will be recovered from specific wells, facilities and completion intervals in the pool and their respective development and production status.

Estimates of reserves and future net revenue for individual properties may not reflect the same confidence level as estimates of reserves and future net revenue for all properties, due to the effects of aggregation. Additionally, all estimates of future net revenue, whether calculated without discount or using a discount rate, do not represent fair market value.
