DNO Participates in Mistral Discovery; Eyes Quick Tieback

Oslo, 5 March 2025 - DNO ASA, the Norwegian oil and gas operator, today

confirmed a gas/condensate discovery on the Mistral prospect in the Norwegian

Sea license PL1119 in which the Company's wholly-owned subsidiary DNO Norge AS

recently acquired a 10 percent interest.

The well encountered a 45-meter hydrocarbon column with good reservoir

properties in the Garn Formation. Preliminary estimates of gross recoverable

resources encountered are in the range of 19-44 million barrels of oil

equivalent. In addition to DNO, license partners include Equinor Energy AS (50

percent and operator), OKEA ASA and Pandion Energy AS (20 percent each).

Located some 20 kilometers southwest of Equinor's ongoing Lavrans subsea

development, the Mistral discovery is a candidate for a fast-track tieback to

this field. Given the good reservoir properties, the discovery likely allows for

simplified development solutions.

To diversify its exploration portfolio, DNO entered into the Mistral license

through a swap agreement with OKEA announced on 19 December 2024, shortly before

spud date of the discovery well. In exchange, OKEA picked up a 10 percent

interest in North Sea license PL1109 containing the Horatio prospect, in which

DNO has retained a 20 percent interest. Exploration drilling is ongoing at

Horatio. The DNO-OKEA transaction is subject to government approval.

Further south, DNO is currently drilling its Kjøttkake exploration well in North

Sea license PL1182S in which the Company holds a 40 percent operated stake.
