Sonoro Gold Corp. report assay results from the final seven drill holes, completing the Phase IV drilling program at its Cerro Caliche gold project in Sonora, Mexico. In total, the Company completed over 7,200 meters of reverse circulation drilling with 63 drill holes which returned multiple higher-grade gold intercepts and demonstrated the expansion of several known mineralized gold zones within the Cerro Caliche concession.

The objective of the program was to increase the estimated size and grade of the project's oxide gold mineralization, as well as to extend the estimated life of a proposed heap leach mining operation as outlined in the Preliminary Economic Assessment (“PEA”) and updated Mineral Resource Estimate filed under the Company's profile on SEDAR on October 29, 2021. On May 9, 2022, the Company announced positive results of an updated PEA based on an optimized mine plan to potentially increase the project's previously reported economic parameters. The updated report was based on the same mineral resource estimate contained in the Company's initial PEA and did not include the new geological data from the Phase IV campaign.

Drilling results from the now completed Phase IV campaign will be included in an updated resource estimation scheduled to be announced in the fall of 2022. The economic impact of the updated resource on the proposed heap leach mining operation is also to be assessed and will be contemplated in a further technical report. The results announced in this news release reflect drilling activity conducted at the Abejas gold mineralized zone located at the eastern perimeter of the Central Pit Zone, with the reported intercepts situated outside of the pit shell used to calculate the mineral resource estimate in the initial PEA.
