SONORO PROVIDES UPDATE TO ALL-IN SUSTAINING COST FOR PEA COMPLETED
ON THE CERRO CALICHE GOLD PROJECT
VANCOUVER, Canada, September 16, 2021 – Sonoro Gold Corp. (TSXV: SGO | OTCQB: SMOFF | FRA:
23SP) (“Sonoro” or the “Company”) wishes to correct a calculation error regarding the all-in sustaining
cost (“AISC”) disclosed on September 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 US$489.3 million LOM, and US$1,462 per ounce (“oz.”) of gold equivalent
(“AuEq”). The corrected amounts, as reported in the table below, are US$437 million LOM, and US$1,351
per oz. AuEq.
The other results of the PEA reported in the Company’s September 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, Ontario (“D.E.N.M.”).
