Reserve and Resource Highlights
Total Reserves and Resources 锟� Colombia:
The table below summarizes the Company锟絪 aggregated 2025 year-end reserves and resources based on the current working interests held by the Company through MKMS Enerji Sucursal Colombia (锟組KMS Colombia锟�), the Colombian branch of the Company锟絪 indirect wholly owned subsidiary, MKMS Enerji Anonim Sirketi S.A. (锟組KMS锟�), in the Sinu-9 Block and Maria Conchita Block, being a 39% non-operating working interest in the Sinu-9 Block and 80% working interest in the Maria Conchita Block.
As announced in the Company锟絪 news release dated January 6, 2026, subsequent to year-end (December 31, 2025), the Company, through MKMS and MKMS Colombia, completed its previously announced transactions with: (i) Etablissements Maurel & Prom S.A. (锟組aurel & Prom锟� or 锟組&P锟�) for the sale of a 40% operating working interest in the Sin锟�-9 Block for total cash consideration of US$150 million; and (ii) the minority partners at the Sin锟�-9 Block, together with Maurel & Prom, for the acquisition of a collective 28% working interest in the Sin锟�-9 Block (collectively, the 锟絊inu-9 Transactions锟�). The table below summarizes the adjusted reserves and resources reflecting the 39% non-operating working interest in the Sin锟�-9 Block that the Company now holds.
Maria Conchita Block (80% WI):
Commencement of Drilling Hechicero-1X
The Company is also pleased to announce that Maurel & Prom, the operator of the Sin锟�-9 Block, has commenced drilling operations at the Hechicero-1X exploration well. Hechicero-1X represents the first well in a planned six-well drilling program at the Sin锟�-9 Block for 2026, leveraging Maurel & Prom锟絪 extensive operational expertise in onshore natural gas development, positioning the joint venture to efficiently fast-track and unlock Sinu-9锟絪 potential.
The Hechicero-1X well is being drilled from the same platform as the Brujo-1X well (which previously tested 51 MMcf/d) and is targeting prospective natural gas-bearing sands in the Ci锟絥aga de Oro formation, with additional potential in underlying Basal sandstones. Drilling is being conducted using a state-of-the-art 1,500-horsepower hydraulic / automated rig, with an anticipated total vertical depth of approximately 8,800 feet.
In support of ongoing development, the Sin锟�-9 Block benefits from existing transportation infrastructure with a current capacity of 30 MMcf/d to deliver natural gas to market. This capacity is scheduled to expand to 40 MMcf/d at the beginning of Q2 2026, enhancing the project锟絪 ability to monetize discoveries promptly and contribute to Colombia's growing demand for clean, reliable natural gas.
Maria Conchita Operational Update
The Company is also pleased to provide an operational update on the Maria Conchita Block.
The workover of the Aruchara-3 well was successfully completed on December 22, 2025, with the recovery of mechanical obstructions and subsequent recompletion of the well. The field is currently producing at a stable rate of 12.0 MMcf/d. The Company is planning a sand cleanup operation in the wellbores of the Aruchara-3 and Aruchara-4 wells during March 2026, which is expected to further optimize and increase production rates.
The Company has received drilling approval for the Aruchara-5 development well from the Agencia Nacional de Hidrocarburos (ANH) and has initiated the contracting process for civil works and key service providers. The Company anticipates spudding the well by the end of March 2026.
These activities support the Company锟絪 ongoing efforts to expand production capacity at Maria Conchita, where current infrastructure supports up to 30 MMcf/d following recent expansions.
锟絆ur 2025 year-end reserves and resources reports demonstrated a substantial increase in net present value across our two conventional onshore natural gas fields, driven by Sproule ERCE锟絪 updated price deck that acknowledges Colombia锟絪 ongoing natural gas supply deficit, which is expected to persist for years to come,锟� said Brian Paes-Braga, Executive Chairman of NGE. 锟紸fter a year dedicated to infrastructure expansion, we now have the processing and transportation capacity in place to swiftly bring new production online. We are thrilled to collaborate with Maurel & Prom on the six-well drilling program at Sinu-9, capitalizing on their proven expertise in onshore natural gas operations to accelerate production growth and help meet Colombia锟絪 domestic natural gas needs. Infrastructure enhancements continue, with drilling and development activities advancing concurrently throughout the year. At Maria Conchita, the Aruchara-5 well is set to be spudded by the end of March, with further optimizations planned for the field锟絪 existing producing wells.锟�
