Eco Atlantic Secures Exploration Right and Transfer of 75% Interest in Block 1 - South Africa's Orange Basin

TORONTO, ON / ACCESS Newswire / June 4, 2025 / Eco (Atlantic) Oil & Gas Ltd. (AIM:ECO)(TSXV:EOG), a leading independent oil and gas exploration company focused on the Atlantic Margin, is pleased to announce that, further to the Farm-In Agreement announced on 5 June 2024, formal approval has been received from the South Africa Department of Mineral and Petroleum Resources for both the Exploration Right and Section 11 transfer. Accordingly, Eco has now secured a 75% Working Interest and full Operatorship of Block 1 offshore South Africa - one of the most strategically positioned assets in the highly prospective Orange Basin. The Section 11 approval was the final condition precedent to establishing full legal transfer of Eco's working interest in Block 1 from Tosaco Energy (Proprietary) Limited ("Tosaco"), and the associated milestone payment has been made by Eco.

This acquisition, completed through Eco's wholly owned subsidiary Azinam South Africa Limited ("Azinam"), significantly expands the Company's Southern African Orange Basin footprint and positions it as a key Operator at the forefront of one of the world's most active and hydrocarbon-rich basins. The remaining 25% interest is held by Tosaco.

Block 1, which spans a vast 19,929km², straddles the border between South Africa and Namibia - directly adjacent to recent world-class discoveries by Galp Energia (Mopane), Shell (Graff, La Rona), TotalEnergies (Venus), Rhino Resources (Capricornus-1X), and the legacy Kudu Gas Field. The block offers full margin transect coverage from the shoreline to deepwater (shore to 263km offshore, in water depths up to 1,000m), encompassing both shallow and deepwater exploration potential.

As previously announced, Eco has already acquired and is analyzing an extensive and high-quality dataset, including both 2D and 3D seismic surveys and regional well logs. The block includes the historic Soekor AF-1 gas discovery, which tested at 32.4 MMscfd, and Soekor AE-1, which encountered oil and gas shows which provides clear evidence of an active petroleum system.

The Company anticipates launching a formal farm-out process in respect of its interest in Block 1 in August 2025, with respect to which further updates will be provided in due course.

Block Summary:

  • Area: 19,929km² offshore South Africa

  • Location: Strategically positioned on the South Africa-Namibia maritime border

  • Extent: From shoreline to ~263km offshore, covering the full margin transect

  • Geological Scope: Broad spectrum of shallow and deepwater oil and gas prospects

  • Water Depths: Shallow shelf to deepwater environments up to 1,000 meters
