Gil Holzman, President and Chief Executive Officer of Eco Atlantic, commented: 

"The year to 31 March 2025 was highly active and saw Eco deliver progress across its existing portfolio, in addition to the Company adding new and exciting exploration assets into the fold.

In South Africa, we continue to work with our Joint Venture Partners on Block 3B/4B, in order to undertake a drilling campaign as soon as is practically possible.  We are currently awaiting the final environmental permits from the South African government agencies and will update our stakeholders on the likely timings in due course.  On Block 1, we have already received early, informal, interest from a number of parties and we plan to launch a formal farm out process towards the end of August 2025.  We have acquired all existing 3D and 2D seismic surveys previously shot on the block and we are busy with the initial interpretation, including the mapping of all oil and gas targets and leads.  The Orange Basin has become one of the most attractive exploration destinations for global oil and gas companies, so we are excited about what the future has in store for Block 3B/4B and Block 1.

Guyana continues to be one of the most prolific hydrocarbon regions in the world, and our farm-out process for the Orinduik Block remains ongoing, including a reassessment by our team of the Jethro discovery parameters.

The remainder of 2025 and into 2026 has the potential to be a highly exciting period for Eco.  We have farm-out processes underway, data analysis ongoing and a drilling campaign to plan for.  All of which has the potential to deliver significant value for all of Eco's stakeholders in due course."
