Grand Cayman, Cayman Islands--(Newsfile Corp. - December 5, 2025) - Tethys Petroleum Limited (TSXV: TPL) ("Tethys" or the "Company") is pleased to provide an update on the Company's operations in the Republic of Kazakhstan.

Operations update

Oil production is continuing from wells KBD-02, KBD-06, and KBD-07, with an average of about 380 tons per day over the last month. The second gas turbine has been successfully repaired and this is expected to increase the gas utilization capacity of daily oil production to about 480 tons per day as of today. Currently, pre-commissioning of the second gas compressor is ongoing. It's anticipated that daily oil production will increase to about 530 tons after the second compressor is put into operation within a week.

Upgrading the oil processing and storage capacity of the Central Processing Facility in the Kul-Bas Oil Field has been underway. It's scheduled to be commissioned by mid-January 2026.

Construction of the Gas Processing Facility and Gas Pipeline (6" x 18 km) Project has been currently at the design stage. The facilities are scheduled to be commissioned and put into operation by October 2026.

Natural Gas production from the Kyzyloi and Akkulka Gas Fields is averaging about 222,000 m³ per day from 21 gas wells. Workover and Well Services operations are currently being performed to reactivate several previously suspended gas wells.

Evaluation of the Aral-4 prospect is ongoing. The Company is also advancing permitting and preparatory work for exploration drilling at two priority sites. Seismic interpretation for the Diyar block is in progress. In addition, analysis of vintage 2D seismic data for the northern part of Diyar and the southern parts of the Zhanasu and Nurzhau blocks continues as part of the ongoing prospectivity assessment.

Regulatory Update
