Trillion Energy International has finalized the design and tender of a new 40-kilometre 2D seismic acquisition program on the M47c,d oil block (the “M47 Block”) in southeastern Türkiye, following its recently completed field scouting program, and is conducting a new seismic tender, with acquisition targeted for the summer of 2026.

The finalized program covers a 40-kilometre 2D seismic survey across three priority exploration areas: the South Lead along the southeastern boundary, the North field discovery area, which includes the area around Çetinkaya-1 and Çetinkaya-2 wells drilled in 2025.

The new program covers key areas where drilling is expected to assist in future development and exploration on the block. Tender documents have been prepared for relevant contractors.

The program design builds on the Company’s recently completed field scouting and high-resolution gravity study (see the Company’s June 30, 2026, news release), which confirmed significant fault-related structures and priority leads across the license. The seismic lines have been positioned to tie into recent discoveries on the adjacent block. Technical specifications for the seismic tender are complete, and the tender is expected to commence shortly, with advance site preparation expected to shorten the acquisition schedule and lower program costs.

The Company expects to acquire the seismic during late summer 2026 and to complete the new acquisition over approximately a six-week period, with data interpreted thereafter. Upon completion, the Company expects to announce its next drilling locations.

Scott Lower, President of Trillion Energy, stated: “New seismic acquisition significantly advances the commercialization and exploration of the M47 Block forward. Some of the most important and prospective areas of the block have not been sufficiently imaged to date. Once it is interpreted, new well locations may be finalized for the upcoming drilling programs as we move one step closer to commerciality and sustained production.”

Project Highlights:

• 2C Contingent Resource of 27.6 MMbbl on the North Discovery, with an unrisked NPV-10 of US$733.5 million.
• Approximately 11 km from the Şehit Aybüke Yalçın oil field, Türkiye’s largest onshore oil discovery,
• Light oil discovery confirmed at 32.4° API gravity (2025)
• 38 metres of net oil pay at C-1 discovery well (2025)
• Total unrisked resource potential of 51.6 MMbbl net to Trillion across three prospects, with a North Prospect 3C estimate at an unrisked NPV-10 of USD$1.18 billion.
• Seven newly discovered analog oil fields in the Gabar region over the past five years
• Analog Gabar regional fields produce a combined rate of over 80,000 bbl/d
• 578,213 MSTB PIIP (100% interest) assessed by appraisal
