SONORO PROVIDES UPDATE TO ALL-IN SUSTAINING COST FOR PEA COMPLETED ON THE CERRO CALICHE GOLD PROJECT

Sonoro Gold Corp. has corrected a calculation error regarding the all-in sustaining cost (AISC) disclosed on Sept. 15, 2021, as part of the results from an independent preliminary economic assessment (PEA) and updated mineral resource estimate completed on the company's Cerro Caliche gold project located in Sonora state, Mexico.

Due to the inadvertent inclusion of certain tax and depreciation expenses in its calculations, the company reported the AISC to be $489.3-million (U.S.) for life of mine and $1,462 (U.S.) per ounce of gold equivalent. The corrected amounts, as reported in the attached table, are $437-million (U.S.) for life of mine and $1,351 (U.S.) per ounce gold equivalent.

The other results of the PEA reported in the company's Sept. 15, 2021, announcement remain unchanged. The PEA has been prepared in accordance with the requirements of National Instrument 43-101 by D.E.N.M. Engineering Ltd. of Burlington, Ont.
