PEL 83 EXPLORATION CAMPAIGN UPDATE 4 - NEW SIGNIFICANT LIGHT OIL DISCOVERY & SUCCESSFUL APPRAISAL AT MOPANE-2X

Sintana Energy Inc. has provided the following update regarding the continuing exploration campaign on blocks 2813A and 2814B located in the heart of Namibia's Orange basin, emerging as the one of the world's most prospective oil and gas regions. The blocks are governed by petroleum exploration licence 83 (PEL 83), which is operated by a subsidiary of Galp Energia of Portugal. Sintana maintains an indirect 49-per-cent interest in Custos Energy Pty. Ltd., a 10-per-cent-working-interest owner in PEL 83. NAMCOR (National Petroleum Company of Namibia) also maintains a 10-per-cent working interest.

The company refers to press releases from Galp and Custos, noting that, further to previous updates provided in January, Galp, together with its partners NAMCOR and Custos, has successfully drilled the Mopane-2X well to its designated depth on PEL 83.

Drilling operations encountered a significant column of light oil in reservoirs of high quality.

The AVO-3 exploration target, the AVO-1 appraisal target and a deeper target were fully cored and logged.

The AVO-1 appraisal target found the same pressure regime as in the Mopane-1X discovery well located approximately eight kilometres to the east, confirming its lateral extension.

The rig will now return to the Mopane-1X well location to conduct a drill stem test until early April.

Galp will continue to analyze the acquired data during the coming weeks to assess the commerciality of the discoveries.

PEL 83 is located immediately north of PEL 39, home to Shell's basin-opening discoveries at Graff-1, La Rona-1 and Jonker-1. Additionally, it is located north and east of PEL 56, where TotalEnergies announced its giant oil discovery at Venus-1.

"The continuing success of the exploration campaign further demonstrates the scope and potential of PEL 83. We extend our further congratulations to our partners Galp and NAMCOR," said Knowledge Katti, chairman and chief executive officer of Custos. "This is another significant milestone for Custos positioning us for further growth and continued success underpinned by our unmatched position in the heart of the basin," he added.

"The announcement of another significant discovery and the appraisal success at the upper target is further testament to the hard work and dedication of the partners involved as well as another demonstration of the potential for further growth in our oil industry. With this discovery, we are one step closer to harnessing the full potential of this campaign," said Maggy Shino, Petroleum Commission for the Ministry of Mines and Energy. "We are proud to have achieved this milestone," she added.

"This third light oil discovery in the Mopane complex and the appraisal results at the AVO-1 reservoir eight kilometres away from the 1X location provide further evidence of the scale and quality of our exploration portfolio held through our local partners, including Custos. We continue to be reminded of the timeliness of our entry into Namibia with the ongoing progress and success," said Robert Bose, chief executive officer of Sintana. "We extend our further congratulations to the joint venture partners on this additional success."
