SONORO GOLD ANNOUNCES FURTHER EXPANSION OF CERRO CALICHE GOLD PROPERTY

VANCOUVER, Canada, April 09, 2026 (GLOBE NEWSWIRE) -- Sonoro Gold Corp. (TSXV: SGO | OTCQB: SMOFF | FRA: 23SP) (“Sonoro” or the “Company”) is pleased to announce that, through its wholly owned Mexican subsidiary, Minera Mar de Plata (“MMP”), it has acquired a 100% interest in the Diana mineral concession (the “Diana Concession”), located adjacent to the central-eastern boundary of the Company’s Cerro Caliche gold project in Sonora, Mexico.

Under the acquisition, MMP acquired a 100% interest in the 51-hectare concession from four residents of Sonora, Mexico (the “Vendor”) for a total consideration of a one-time payment of US$600,000. The Vendors are at arm’s length to the Company and to its associates and affiliates. The purchase consideration does not include the issuance of any securities nor any grant of a royalty interest.

The Company believes the Diana Concession to be a possible significant extension of the northwest trending mineralized corridors located north of the Rincón–Bellotoso mineralized zone near the historic workings of El Batamote mine.

Kenneth MacLeod, President & CEO of Sonoro commented, “We have long recognized the potential mineralized value of the Diana Concession as demonstrated by prior exploration programs, but we believe its real potential value was enhanced through the recent extension of the Cerro Caliche project to the north, which almost surrounds the Diana Concession. Combined with historic drilling data, the acquisition enhances the potential for the upcoming 50,000 meters drilling campaign to define a larger resource at Cerro Caliche.”

In 2012, Paget Southern Resources S. de R.L. de C.V., a Mexican subsidiary of Pembrook Mining Corp., completed multiple rock sampling programs as well as six diamond drill holes at Diana and another nine at El Batamote. In 2018, MMP acquired the geological data from a subsequent owner, Millrock Resources, including rock and soil samples, drill logs and assay certificates.  A recently announced 50,000-meter drilling program will also include expansion drilling at the Diana Concession to confirm potential structural continuity of the project’s northwest trending mineralized corridors.

The acquisition of the Diana Concession expands the Cerro Caliche project to twenty-six (26) contiguous mining concessions, covering a total area of 3,975.97 hectares and adding new high-potential exploration targets.

The Cerro Caliche gold project is in the final permitting stage for a proposed initial open-pit, heap leach mining operation. The property hosts a broadly mineralized low-sulphidation epithermal vein structure with over twenty-five (25) northwest-trending gold mineralized zones along trend and near surface.
