CALGARY, Canada (Aug. 26, 2025)—Sonoro Energy Ltd. (“Sonoro” or the “Company”) (TSXV: SNV) announces that it has successfully completed drilling operations at the Countess exploration well, located approximately 10 kilometers west of Brooks, Alberta.

The well was drilled safely to a total depth of 1,180 metres, approximately 20 metres deeper than initially planned, in order to fully penetrate the target formation. During operations, oil was observed to surface in mud returns, and the well encountered approximately 4-5 metres of potential oil pay within the target zone. The calculated average porosity level over the zone was 6%, below thresholds required to justify completing the well. As a result, the well will be cemented and plugged, and the data gathered will be integrated with seismic interpretations to further evaluate the prospective area and the Company’s Pekisko play.

By drilling the Countess Well, Sonoro earned a 100% working interest in 3.5 sections of prospective leases held by Badlands Resources. The Company is currently analyzing the drilling and geological results and may consider drilling a second well on the earned acreage, depending on its technical and economic assessment. Sonoro is the operator of the well and holds a 100% working interest in the project.

In addition to its Canadian operations, the Company continues to advance its strategic initiatives in the Middle East and will provide further updates to shareholders as material developments occur.
