("Block" or the "Company")

Project III Resource Upgrade

Block Energy plc, the development and production company focused on Georgia, is pleased to announce upgraded internal resource estimates for the Rustavi and Teleti fields.

Combined with the independently audited 2C recoverable resources on the Patardzueli-Samgori field, the total Project III 2C Contingent Recoverable Resource figure for Patardzueli-Samgori, Rustavi and Teleti fields now stands at over 2.77 TCF, with an estimated Net Present Value ¹⁰ ("NPV") of USD 1.65 billion.

Internal Resource Upgrade

Following the announcement of the Independent Engineering Report ("IER") by Oilfield Production Consultants ("OPC") on Patardzueli-Samgori, the Company has reviewed and updated its internal estimates for the Rustavi and Teleti fields in line with the methodologies applied by the OPC report.

Both the OPC IER and the Block Energy Internal Contingent Resource report only consider gas volumes within the natural fracture system. Upside exists within the tight matrix in both the Lower Eocene and Upper Cretaceous reservoirs. Both reports were completed according to Petroleum Management Resource System ("PRMS") standards.

The upgraded internal contingent resources for these fields are as follows:

The full Project III volumes are therefore as follows:

(Project III Net Present Value ¹⁰ by Field and Case)

The development plan for each field in the mid case sees an early production scheme delivering 30 MMCF/d gas production, rising to plateaus of 200 MMCF/d (each of Patardzueli-Samgori and Rustavi) and 100 MMCF/d (Teleti). Development costs are anticipated to be low on a USD/MMCF basis, given the onshore location of the fields and the proximity of sales infrastructure.

Gas quality in all three fields has consistently high CH₄ content and no H₂S or CO₂ detected within the gas tests undertaken to date. The Company has developed fully costed appraisal programmes for all three fields, with a near-term focus on Patardzueli-Samgori in light of the results of the PAT-E1 well drilled by Schlumberger.

New Corporate Presentation

The Company is also pleased to announce publication of a new corporate presentation. No material new financial or other information has been provided.

Commenting, Paul Haywood, Block Energy Chief Executive Officer said:

"I am pleased to announce upgraded contingent resources across Rustavi and Teleti, which together with the recent IER further confirm our confidence in Project III.

"Project III offers a 2C recoverable contingent resource of nearly 3 TCF, with an NPV of USD 1.65 billion. The Project has the potential for significant gas production rates: 200 MMCF/d for each of Patardzueli-Samgori and Rustavi at plateau, an additional 100 MMCF/d from Teleti, and 30 MMCF/d from early production facilities following the Patardzueli-Samgori appraisal campaign.

"The subsurface team has identified additional prospectivity within the area, which would add further running room to the long-term development of the Project. The recently announced commercial Carbon Capture Storage (CCS) opportunity also highlights the Project's sustainability credentials. Further work is being undertaken on the CCS opportunity and announced in due course.

"Today's announcement underlines the Project's potential to meet Georgia's urgent demand for energy and make a wider regional impact. The proximity of our fields to the South Caucuses Pipeline (SCP) opens up competitive export opportunities in Turkish and Southern European gas markets - including Italy and Greece - through the connection to the Trans Anatolian Natural Gas Pipeline (TNAP) and the Trans Adriatic Pipeline (TAP).

"The farm-out campaign is on schedule with ongoing discussions with a range of interested parties."

Notes to editors

Block Energy plc is an AIM-listed independent oil and gas production and development company with a strategic focus on unlocking the energy potential of Georgia. With interests in seven Production Sharing Contracts in central Georgia, covering an area of 4,256 km2, including the XIB licence which has over 2.77TCF of 2C contingent gas resources, with an estimated Net Present Value ¹⁰ ("NPV") of USD 1.65 billion, in the Patardzueli-Samgori, Rustavi and Teleti fields. (Source: IER, OPC 2024 & Internal estimates).

The Company has structured its operations around a four-project strategy. These projects, characterized by development stage, hydrocarbon type, and reservoir, are pursued concurrently to achieve multiple objectives. This includes increasing existing production, redeveloping fields, discovering new oil and gas deposits, and capitalizing on the substantial, yet untapped, gas resource across its licences. The goal is to deliver on multi TCF gas assets, strategically well located for the key EU market, supported by partner funding and cash from existing producing assets.

Located near the Georgian capital of Tbilisi, Block Energy is well-positioned to contribute significantly to the region's energy landscape. This proximity facilitates seamless operations and underscores our commitment to the economic and energy development of Georgia.
