SONORO FILES UPDATED PRELIMINARY ECONOMIC ASSESSMENT ON SEDAR


VANCOUVER, Canada, June 23, 2022 (GLOBE NEWSWIRE) -- Sonoro Gold Corp. (TSXV: SGO | OTCQB: SMOFF | FRA: 23SP) ("Sonoro" or the "Company") is pleased to report the filing of a technical report titled "Updated Preliminary Economic Assessment of the Cerro Caliche Project, Sonora, Mexico" (the "PEA") with an effective date of May 9, 2022.

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."), with David Salari, P.Eng. as the lead author. William Lewis, P.Geo., of Micon International Limited of Toronto, Ontario ("Micon") was the Qualified Person responsible for the mineral resource estimate.

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").

The PEA can be found under the Company's profile at www.sedar.com and on Sonoro's website at www.sonorogold.com.

PEA Highlights:

Note: All currencies are reported in U.S. dollars. Base case parameters assume $1,750/oz of gold and $22/oz of silver.
(1) Cash costs include mining, crushing, processing, assaying, and administration.
(2) All-in-Sustaining Costs include cash costs plus sustaining, refining and reclamation costs, as well as 2% royalties.

Mineral Resource Estimate
The updated PEA utilizes mineral resource estimate contained in the Company's initial PEA, dated October 29, 2021, and is based on the Company's September 2018 to April 2021 drilling campaigns.

Readers are cautioned that these potential mineralization ranges are conceptual in nature and that despite being based on a limited amount of exploration drilling and sampling outside the current resource pit shells, it is uncertain that further exploration will result in the mineralization targets being delineated as a mineral resource.

Drilling Data
Approximately 7,200 meters of additional drilling recently completed at Cerro Caliche was not included in the current mineral resource estimate. The new geological data is to be included in an updated resource estimate scheduled to be filed in the fall of 2022.

Since drilling resumed in November 2021, the Company has announced multiple high-grade intercepts and expansions of several known mineralized zones in the southwestern region of the property. The potential economic impact of the updated resource on the proposed heap leach mining operation will be contemplated in a further technical report.

PEA Summary
The PEA is preliminary in nature and includes inferred resources that are considered too speculative to have the economic considerations applied to them that would enable them to be categorized as mineral reserves and there is no certainty the estimates presented in the PEA will be realized.
