Trillion Energy Announces Independent Resource Evaluation

Highlights include 27.6 MMbbl 2C (unrisked) Contingent Oil Resource to Trillion on North Lead Discovery;

Trillion Energy International Inc. (“Trillion” or the “Company”) announces the results of an independent evaluation of contingent and prospective oil resources for Block M47C3,C4 in Southeast Türkiye, prepared by Chapman Hydrogen and Petroleum Engineering Ltd. (“Chapman”) of Calgary, Alberta, in accordance with National Instrument 51‑101 (“NI 51‑101”) and the Canadian Oil and Gas Evaluation Handbook (“COGEH”) effective March 31 2026.

Highlights

• 2C Contingent Resource of 27.6 MMbbl (24,186 MSTB net) on the North Discovery, with an unrisked NPV‑10 of US$733.5M and a risked expected value of US$594.2M (81% chance of development) net to Trillion’s 29% working interest.
• Total Block M47C3, C4 unrisked resource potential of 51.6 MMbbl net to Trillion across three prospects - North (Contingent), Central, and Findık (South), all targeting the Cretaceous Mardin Group carbonate reservoir.
• Light oil confirmed at 32.4° API gravity at both C‑1 and C‑2 wells; 38 metres of net oil pay at C‑1 with water saturation as low as 8%. Both wells were drilled on the structural flank; the structural crest remains untested.
• The M47 block lies approximately 11 kilometres from the Şehit Aybüke Yalçın oil field, Türkiye’s largest onshore oil discovery, the Şehit Esma Çevik oil field (5–6 km), Yağizoymak field (approximately 2 km), and Bulmuşlar field (approximately 4 km), all of which produce from the Beloka and Mardin Group carbonates and which are analogue fields.

About The M47 Concession
The M47c,d Concession is located in Southeastern Türkiye, within the Cudi-Gabar petroleum province. The block contains three identified prospects: the North, Central, and Findık (South) prospects, targeting the Early Cretaceous Beloka and Mardin Group carbonate reservoirs. Two wells (Çetinkaya C‑1 and C‑2) have been drilled on the North Prospect, both confirming the presence of 32.4° API light oil based on log analysis and independent petrophysical evaluation of recovered oil. The Company has the right to earn a 29% working interest in the M47 Concession following its agreement with Derkim Petrolüm, subject to fulfillment of the earn-in obligations.

Resource Evaluation Summary

1 MMbbl = 1,000 MSTB. Monetary values in US dollars. M$ = thousands of dollars. “Gross” resources in this table represent the Company’s 29% working interest share before deduction of royalties owned by others (i.e., before the 12.5% government royalty on the North Prospect); they are not 100% block volumes. “Net” resources represent the Company’s 29% working interest share after deducting royalties. NPV discounted at 10% per year before income tax. North Prospect Contingent Resources are classified as Economic Contingent Resources (positive NPV at forecast prices) with a Project Maturity Sub-class of Development Unclarified. Risked Expected Value (2C) applies Chapman’s assigned 81% Chance of Development to the unrisked 2C case in accordance with COGEH. Prospective Resource after-risk NPV applies Chapman’s assigned Chance of Commerciality (Central 31%; Findık 36%) to the unrisked P50 (arithmetic average) case. Chance of Discovery: Central 38%, Findık 45%. Initial production rates assumed: 800 STB/d per well (Best Estimate), 500 STB/d (Low Estimate), 1,000 STB/d (High Estimate). See “Economic Assumptions” section below for price deck, cost and fiscal assumptions. Columns may not add precisely due to accumulative rounding. Full 1C, 2C and 3C Contingent Resource tables follow below.

Table 2 – Contingent Resources (1C Low Estimate) – North Prospect, Block M47, Mardin Group

1C = Low Estimate (conservative). Expected Value (1C) applies 81% Chance of Development. Gross/Net definitions as per Table 1 footnote above. All values before income tax.

Table 3 – Contingent Resources (3C High Estimate) – North Prospect, Block M47, Mardin Group

3C = High Estimate (optimistic). Expected Value (3C) applies 81% Chance of Development. Gross/Net definitions as per Table 1 footnote above. All values before income tax.

North Prospect – Contingent Resources

• 2C Contingent Resources of 27.6 MMbbl (24,186 MSTB net after royalty); unrisked NPV‑10 of US$733.5 M; risked expected value of US$594.2M (81% chance of development). Çetinkaya C‑1 and C‑2 confirmed 32.4° API light oil in Cretaceous Mardin Group carbonate reservoirs with 38 metres of net oil pay at C‑1, water saturation as low as 8%, and confirmed duel matrix and fracture permeability.

Central Prospect – Prospective Resources

• P50 Prospective Resources of 13,093 MSTB net to Trillion’s 29% working interest; unrisked NPV‑10 of US$412.9M; after-risk NPV‑10 of US$127.3M (31% Chance of Commerciality; 38% Chance of Discovery). Seismic-confirmed four-way dip closure on trend with the North Prospect discovery.

Findık (South) Prospect – Prospective Resources
P50 Prospective Resources of 7,895 MSTB net to Trillion’s 29% working interest; unrisked NPV‑10 of US$247.2M; after-risk NPV‑10 of US$88.4M (36% Chance of Commerciality; 45% Chance of Discovery). Four-way dip closure near the North Prospect and off-block producing fields.

Planned Work Program
The North Lead discovery drilling programme is scheduled to commence in 2027, targeting first commercial production by mid-2027, at an estimated cost of US$3.5M per well plus seismic and surface facilities. C1S (C-1 sidetrack well, is estimated cost of US$2M) Production (subject to commerciality) is expected through primary depletion from vertical wells. The Fındık‑2 exploration well is planned for late 2026 (US$3.2M) and the Central exploration well for late 2026/early 2027 (US$3.4M).
