SONORO GOLD COMMENCES 50,000 METER DRILLING PROGRAM

Sonoro Gold Corp. will resume drilling at its flagship Cerro Caliche gold project in Sonora state, Mexico. As previously announced, the company will complete a two-phased exploration campaign, including 50,000 metres of reverse circulation drilling, as well as soil and rock sampling programs.

Phase I of the program is expected to be completed by the fall of 2026 and will include 25,000 metres of drilling with approximately 207 drill holes and 6,000 soil samples. Phase II will continue uninterrupted until the spring of 2027 with 25,000 metres of drilling and approximately 220 drill holes and 3,000 soil samples. Access roads to the drill sites have now been upgraded and drill pads are near completion. Drilling will commence with CANMEX Perforaciones y Servicios SA de CV on May 11, 2026.

The program will initially focus on infill drilling at several known gold mineralized zones where prior drilling campaigns returned multiple higher-grade gold intercepts within larger intervals of high-grade gold mineralization. The objective is to potentially increase the size, grade and classification of the project's mineral resource.

"We are excited to resume drilling at Cerro Caliche with the largest drilling campaign since we acquired the project in 2018," said Kenneth MacLeod, president and chief executive officer of Sonoro. "While the recently announced results of our updated PEA demonstrated an economically robust project, the report was based on geological data gathered from less than 30 per cent of the known mineralized zones identified on the original 1,350-hectare property. The recent acquisition of 11 mining concessions has increased the project to almost 4,000 hectares. The upcoming exploration program is a great opportunity for us to potentially expand the mineral resource, upgrade resource classification and confirm the extensions of the project's geological structure."

The program will further investigate previously identified deeper mineralized zones, as well as undertake expansion drilling at certain mineralized corridors where occurrences suggest consistent geology and the potential expansion of mineralization.

Expansion drilling will also confirm the structural continuity of the northwest-trending mineralized corridors into the recently acquired northern and eastern concessions. A review of historical geological data, from prior exploration programs completed on the new concessions, demonstrates comparable geological characteristics and grades to the project's known gold mineralized zones.

The 50,000-metre reverse circulation drilling campaign will proceed alongside the proposed development of an open-pit, heap leach mining operation currently in the permitting phase for an initial 10-year production at a projected capacity of up to 16,000 tonnes per day.
