Sonoro Gold Corp. announced the positive results of an updated independent Preliminary Economic Assessment ("PEA") on the Company's Cerro Caliche gold project located in Sonora State, Mexico. The updated PEA highlights several opportunities to potentially increase the project's previously reported economic parameters, as well as potentially lower several identified risks.

As the engineering and costing outlined in both the initial and updated studies are at the PEA level, potential variations in operation and capital costs may occur. Based on the same mineral resource estimate contained in the Company's initial PEA, dated October 29, 2021, the updated PEA contemplates an optimized mine plan for an open pit, heap leach mining operation with an initial two-year production rate of 8,000 metric tonnes per day ("mtpd") and an increase to 15,000 mtpd for the remaining life of mine ("LOM").
