Sonoro Energy provides operational update on Countess Well in Alberta

CALGARY, Canada (June 16, 2025)—Sonoro Energy Ltd. (“Sonoro” or the “Company”) (TSXV: SNV) is pleased to provide an operational update on the Countess exploration well located in southern Alberta.

The Company has advanced operational planning for the drilling of its Countess well, located at 04-15-19-15 W4, approximately 10 kilometers west of Brooks, Alberta. Sonoro is the operator of the well and holds a 100% working interest in the project.

Survey work has been completed, and the Company is in the final stages of securing all necessary site approvals, including environmental, wildlife corridor and surface location permits. Consultation with the surface rights owner and local residents has also been completed. No concerns or objections have been raised, and Sonoro anticipates that all required approvals will be in place before the end of June.

By drilling the Countess well, Sonoro will earn a 100% interest in 3.5 sections of prospective leases currently held by Badlands Resources. Several similar follow-up prospects have already been mapped on this acreage, reinforcing the strategic importance of this initial test well.

The well will target Mississippian-aged carbonate formations at an estimated depth of approximately 3,500 feet. Drilling operations are expected to commence in July/August, based on rig availability, and take approximately one week to reach total depth.

Sonoro is in the final stages of securing a drilling rig that is already mobilized within the region, which is expected to provide savings on transportation and mobilization costs.

“The Countess project represents a significant step forward for Sonoro’s Alberta exploration program,” said Greg Renwick, President and CEO of Sonoro. “We’re excited about testing this geological feature and the oil potential the prospect holds. A commercial discovery at Countess will open up several similar drilling opportunities on the earned acreage to deliver long-term value for our shareholders.”
