SONORO GOLD ANNOUNCES EXPANSION OF CERRO CALICHE GOLD PROPERTY

Sonoro Gold Corp., through its wholly owned Mexican subsidiary, Minera Mar de Plata (MMP), has executed assignment of rights agreements with two residents of Sonora, Mexico (the vendors), to acquire 10 mineral concessions along strike and adjacent to the northern and southern boundaries of the company's Cerro Caliche gold project in Sonora, Mexico. Both vendors are at arm's length to the company and to its associates and affiliates.

Under the agreements, MMP will acquire a 100-per-cent interest in an additional 2,574.16 hectares (ha) of mining concessions for total consideration of $4.0-million (U.S.) to be paid in instalments totalling $1.0-million (U.S.) per year over the next four years. In addition, the company is assuming responsibility for the payment of outstanding mineral concession fees totalling approximately $570,000 (U.S.). The purchase consideration does not include the issuance of any securities nor any grant of a royalty interest.

The acquisition significantly expands the Cerro Caliche property to 25 contiguous mining concessions covering a total area of 3,924.26 hectares, potentially extending known mineralized corridors both to the northwest and the southeast.

"We are pleased to have successfully acquired these strategic mining concessions and expand the project's footprint in Mexico's top gold-producing state. We believe the acquisition not only increases the project's exploration potential but may also expand the known mineralized corridors in the northern and southern regions of the property," commented Sonoro's president and chief executive officer, Kenneth Macleod. Adding, "Our primary objective remains initiating production on Cerro Caliche's central mineralized zones and utilizing generated cash flow for future exploration and potential resource expansion."

On Oct. 12, 2023, Sonoro filed a technical report entitled "NI 43-101 Technical Report for the Preliminary Economic Assessment on the Cerro Caliche Project, Sonora, Mexico," authored by Micon International Ltd., with an effective date of Aug. 28, 2023 (the PEA). As discussed in the PEA, Sonoro has acquired historical geological data from prior exploration programs completed at Cerro Caliche, including drilling, rock sampling and soil sampling data from several of the newly acquired concessions.

In 2011, Paget Southern Resources, a Mexican subsidiary of Pembrook Mining Corp., completed seven diamond drill core holes at El Batamote, approximately 300 metres north of the project's El Rincon-Bellotoso mineralized zone. Drill holes, logs and assays reviewed by the company's geologists identified comparable geological characteristics and grades, suggesting structural continuity of the mineralized corridor. Historical mine workings and exploration completed on newly acquired concessions along the project's southern boundaries also suggest potential continuation of known gold mineralized zones.

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

In November, 2025, Sonoro commenced the preparation of an updated PEA on drilling and assay data completed on approximately 30 per cent of the project's identified mineralized zones. Sonoro anticipates completing the updated PEA during the first quarter of 2026.
