PEL87 EXTENSION GRANTED

Sintana Energy Inc. has provided the following update regarding petroleum exploration licence (PEL) 87, which governs blocks 2713A and 2713B located in the Orange basin offshore in the Republic of Namibia. Sintana has a 7.4-per-cent indirect carried interest in PEL 87.

Pancontinental Energy Ltd., the joint venture partner and operator of PEL 87, has received notification from the Namibian Ministry of Industry, Mines and Energy (MIME) that the minister has granted approval to Pancontinental's application to extend the current first renewal exploration period of PEL 87 by 12 months to Jan. 22 2027. The extension has been granted with the following work commitments to be carried out on PEL 87 during the extension period:

• Undertaking of an environmental impact assessment (EIA);
• Reprocessing of 3-D seismic data and seismic interpretation;
• Drilling of an exploration well.

The EIA is well progressed, having commenced in 2025, with the seismic reprocessing work program focusing on a subset of PEL 87 3-D. The main purpose of the seismic work will improve seismic signal quality in specific areas.

Robert Bose, chief executive officer of Sintana Energy, commented: "We are grateful to the minister for the extension of PEL 87. We look forward to the continued refinement of the existing seismic work in anticipation of securing a farm-in partner to progress the project to a focused drilling program."
