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

"We are pleased to have agreed terms alongside our partners for the farm out of XIQ to a leading international E&P company.

"The successful conclusion of negotiations represents a major step for the development of the XIQ license and a material milestone for Block Energy and our shareholders. The significant proposed investment by a company with an excellent track record for exploration underlines the quality of our asset base and the prospectivity within the basin.

"Whilst there can be no certainty that the transaction will complete, the effort and progress from the XIQ partners and farminee provides confidence in a successful outcome. At completion, the agreement will not only unlock the potential of XIQ but should provide momentum to the ongoing farmout of Project III as well as other licenses within the Project IV portfolio.

"We look forward to concluding the farmout agreement with our new partner and publishing full details of the transaction with our stakeholders at completion."

Licence XIQ & Work Programme:

Licence XIQ is located immediately to the north of Block's existing XIB contract area and contains significant prospectivity, as defined in the independent DeGoyler MacNaughton prospective resource report (2023).

The primary target of the farm-in is the Martkopi Terrace prospect, a structure identified on 2D and 3D seismic in close proximity (c. 10km) to the prolific Patardzueli-Samgori field which produced c. 180 MMbbl from the same target reservoir.

The agreed farm-in work programme includes 3D seismic acquisition and the option to fund of up to three deep, high-impact wells, at which point the farm-in partner will become the operator.

On completion of the work programme, the farmin partner will have the option to move to 92.5% in the XIQ license, in return for cash payments and a royalty to the existing parties.

Block currently holds a 10% interest in the XIQ licence, with an option to increase this to 22%.

Project IV Background

Project IV refers to Block's exploration activities within its portfolio in Georgia. This includes the highly prospective XIQ licence (Block 10% with an option to increase to 22%), IX licence (Block 100%) and the XIH licence (Block has an option to acquire 22%).

The XIH licence, which is also subject to farmout discussions, is located immediately to the south of Block's existing XIB licence and covers an area of 486 km². Seven structures have been identified within the XIH licence and DeGoyler MacNaughton (2023) ascribe a total of 485.7 MMboe of mean unrisked recoverable prospective resources.

A further notification will be made once the licence holders have received the government of Georgia's decision on the submission.
