TETHYS PETROLEUM PRESS RELEASE: INTERIM RESULTS AND CORPORATE UPDATE

Tethys Petroleum Ltd. has filed its interim results for the three months ended March 31, 2023. The full interim results together with management's discussion and analysis have been filed with the Canadian securities regulatory authorities. Copies of the filed documents may be obtained via SEDAR or on Tethys's website.

Regulatory and operations update

The company is prioritizing efforts to achieve a commercial licence at the earliest possible date. The field development project for Kulbas includes regulatory approvals from multiple bodies, including the Ministry of Ecology and Natural Resources as well as the Ministry of Energy. The current schedule includes a shutdown of oil production in October, 2023. In the interim, the company is trying to maximize production from the pilot production wells (KBD-02, KBD-06 and KBD-07) as well as the new exploration wells (KBD-10 and KBD-11). Oil production in April averaged about 400 tons per day, up from 370 tons per day averaged for the first quarter of 2023. Recent production in May has increased to about 650 tons per day.

The drilling on KBD-10 had been delayed due to a shortage of necessary casing materials, but this has now been resolved and drilling has restarted. KBD-11 drilling is completed and will commence test production in the Barremian zone within a week.

Gas contract negotiations

The company is continuing to pursue a resolution with QazaqGaz in regards to payment and price for gas production. The gas fields remain shut in.

Normal course issuer bid update

As of May 17, the company has repurchased 73,285 shares of the 5,805,361 common shares approved under the new program for this year that will expire Feb. 10, 2024.
