SONORO GOLD COMPLETES ACQUISITION OF 23 MINERAL CONCESSIONS TO FURTHER EXPAND THE CERRO CALICHE GOLD PROJECT

VANCOUVER, Canada, Aug. 26, 2026 (GLOBE NEWSWIRE) -- Sonoro Gold Corp. (TSXV: SGO | OTCQB: SMOFF | FRA: 23SP) (“Sonoro” or the “Company”) is pleased to announce that its wholly owned Mexican subsidiary, Minera Mar de Plata (“MMP”), has completed the acquisition of additional mineral concessions located adjacent to the Company’s Cerro Caliche gold project in Sonora, Mexico.

As previously announced on May 12, 2026, the Company executed Letters of Intent to acquire a 100% interest in 23 mineral concessions and up to a 51% interest in five additional mineral concessions.

The completed acquisition is a strategic opportunity to potentially demonstrate the Cerro Caliche project as being part of a larger gold epithermal system, with wide-scale potential to host multiple mineralized zones. Historical data from multiple exploration programs conducted on and surrounding the newly acquired mineral concessions suggest geological, structural and mineralization characteristics similar to those identified at Cerro Caliche.

Kenneth MacLeod, President and CEO of Sonoro Gold, commented, “The recent expansions at Cerro Caliche provide us with the potential to materially enhance the scope and scale of the project. Our current 50,000 metre drilling program is focused on potentially increasing the size, grade and classification of the project’s mineral resource, as well as investigating the expected continuation of the mineralized corridors into these new concessions.”

TRANSACTION SUMMARY

• Vendors are at arm’s length to the Company, its associates and affiliates and the purchase consideration does not include the issuance of any securities, nor any grant of a royalty interest.

• 100% interest in 23 mineral concessions over 4,239.10 hectares (ha) for total consideration of USD $5.17 million to be paid in installments over 18 months.

• MMP assumes certain liabilities of outstanding mineral concession fees totaling approximately USD $990,000.

• 51% interest in five mineral concessions over 453.91 ha for a total commitment of up to USD $9M in exploration and development expenditures.

Since January 2026, Cerro Caliche has been strategically expanded from 1,350-hectares to 8,215-hectares, plus a 51% interest in another 454 hectares.

The Cerro Caliche gold project is in the final permitting stage for a proposed initial open-pit, heap leach mining operation.

An updated 2026 PEA on the original 1,350 ha Cerro Caliche property demonstrates the potential viability for a ten-year open pit, heap leach mining operation at 16,000 tpd. Based on approximately 30% of the known mineralized zones identified on the original property and utilizing a gold price of USD $3,500 per ounce, the report highlights an after tax NPV₈ of USD $224M and an IRR of 50%.
