DUNE OIL COMPLETES CONTRACTOR SITE VISITS AT GABAR BLOCK AND ANNOUNCES PRESENTATION AT ENERCOM DENVER

Prospective seismic acquisition contractors completed site visits to Dune Oil Corp.'s Gabar block in southeastern Turkey on July 29 and July 30, 2026, in preparation for the company's planned 2-D seismic acquisition program.

Contractors and supporting service providers attended alongside the company's technical and operations teams and its partners. They reviewed field conditions, access routes, logistics and equipment requirements across the survey area.

The visits complete the technical basis for the seismic tender. Contractors are now preparing technical and commercial proposals, and the company expects to award the acquisition contract and announce a mobilization date in due course.

The seismic program is expected to improve subsurface imaging across the block, refine existing exploration targets and support future drilling decisions. Upon completion, the company expects to announce its next drilling locations.

The company also announces that it will present at the 31st EnerCom Denver -- The Energy Investment Conference, to be held Aug. 17 to Aug. 19, 2026, at the Westin Denver Downtown in Denver, Colo. Dune's presentation is scheduled for Wednesday, Aug. 19, 2026, at 11 a.m. Mountain Time and will be webcast live. A video replay and the presentation materials will be posted to the conference website following the event.

Conference details are available on-line; attendees can schedule one-on-one meetings with Dune Oil.
