Operations Update

Summary

• The State Agency of Oil and Gas of Georgia confirmed Block's operational rights to the Upper Eocene, Lower Eocene and Upper Cretaceous in the Samgori South Dome ("SSD") field.
• As a result, resources for Project III increase with the addition of 574 BCF 2U unrisked prospective resources to the existing 2.7 TCF 2C contingent resources.
• The consolidation of the field into XIB allows it to be advanced alongside the Project III appraisal plan.

Background

Samgori South Dome ("SSD") was originally part of the XIB PSC but carved-out in 2014 (prior to Block's participation in XIB) for potential use by the Georgian government at Middle Eocene reservoir depth for an Underground Gas Storage ("UGS") project.

The Middle Eocene is retained by the Georgian national oil company, Georgian Oil and Gas Corporation ("GOGC").

Geological Context

At the Lower Eocene and deeper stratigraphy the SSD geological structure is a three-way dip closure forming a culmination in communication with and at a similar structural level to the Patardzueli-Samgori structure, and is on trend with the Teleti field. The Lower Eocene and Upper Cretaceous reservoirs have not been drilled and tested to date, but given the seismic interpretation, depth calibration at the top Middle Eocene and location of the SSD culmination adjacent to proven gas in Patardzueli-Samgori and Teleti it is considered to be highly prospective.

The top Upper Cretaceous structure runs from Patardzueli-Samgori through SSD to Teleti, a distance of approximately 40 km, becoming progressively shallower by around 1,700 m at Teleti. This has the potential to be a continuous gas-bearing structure as no structural closures have been mapped at mid and deep case known gas levels.

Block's internal resource evaluation ascribes the following prospective resources to SSD:

Project III

SSD produced oil from the same volcanoclastic Middle Eocene formation as Patardzueli-Samgori and Teleti during the Soviet period. No exploratory wells targeting the Lower Eocene and Upper Cretaceous were drilled.

Acquiring the SSD field ensures that, on success of the Project III appraisal campaign, the Company has additional running room to add resources to the existing proven fields and that, if the Upper Cretaceous reservoir is shown to extend from Patardzueli-Samgori through SSD to Teleti, the Company is able to exploit this.

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

"We greatly appreciate the continued support of the Georgian government as we advance our Project III farm-out campaign. The acquisition of SSD marks a significant milestone, further strengthening our significant resource base, enhancing the growth potential for the Company. With this expanded opportunity set, we are well-positioned to capitalise on future drilling success across Project III. We look forward to sharing further updates in due course."
