VANCOUVER, Canada, November 18, 2024 – Sonoro Gold Corp. (TSXV: SGO | OTCQB: SMOFF | FRA: 23SP) (“Sonoro” or the “Company”) is pleased to provide a corporate update on the Company’s flagship Cerro Caliche gold project in Sonora, Mexico. In January 2018, the Company executed an Option to Purchase and Promise to Assignment Agreement (the “Option Agreement”) with a resident of Sonora, Mexico (the “Vendor”) to acquire a 100% interest in the Cerro Caliche Group of Concessions (the “Concessions”). The Option Agreement represents 67% of the total surface area of the Cerro Caliche Gold Project, for total consideration of US $2.98M.

On November 8, 2024, the Company paid the final installment of US $250,000 under the Option Agreement, securing a 100% interest in the Concessions through the execution of an Assignment of Title to Mining Concession Agreement (the “Assignment Agreement”). Under the terms of the Assignment Agreement, the Company also executed a Royalty Agreement, entitling the Vendor to a 2% net smelter returns royalty (the “NSR”) from the proceeds of the sale of minerals from the Concessions. The Company may purchase the NSR for US $1,000,000 for each one percent of the royalty after year four of production.

The Cerro Caliche Gold Project is comprised of 15 contiguous mining concessions covering a total area of 1,350.10 hectares (ha). The concessions were optioned in 2018 under five separate option agreements for total consideration of US $5M. Mineral concession titles, under four of the five option agreements, have now been acquired by the Company’s Mexican subsidiary, Minera Mar de Plata (“MMP”), representing over 70% of the property. The remaining concessions will be acquired by MMP in April 2025 upon payment of the final installment due under the remaining option agreement.

Sonoro is in the permitting phase for a proposed open-pit, heap leach mining operation at the Cerro Caliche Gold Project. With only 30% of the project’s identified mineralized zones drilled and assayed to date, Sonoro plans to develop an initial 12,000 tonnes per day operation to generate cash flow for further exploration of the remaining 70% of the mineralized area for mine expansion.

“Despite the recent challenges of distressed capital markets for the precious metals sector as well as permitting delays in Mexico, we continue to maintain concession payments and advance the Cerro Caliche mine plan through the environmental review process,” said Kenneth MacLeod, Sonoro’s President and CEO. “We are encouraged by new President Claudia Sheinbaum’s pragmatic and cooperative approach to the mining industry, compelling Sonoro to vigorously pursue approval of the mine permit application (MIA) which was originally filed with the Mexican environment agency SEMARNAT in May 2022.”

About the Cerro Caliche Gold Project

Exploration to date at the Cerro Caliche Gold Project confirms a broadly mineralized low-sulphidation epithermal vein structure and over 25 northwest-trending gold mineralized zones along trend and near surface. In March 2023, Sonoro filed an updated Mineral Resource Estimate (MRE) based on a total 55,360 meters of drilled data, including 498 drill holes, 17 trenches and assays for 53,865 meters of the drilled data.

In October 2023, Sonoro filed a new Preliminary Economic Assessment (PEA) demonstrating the potential viability for a 9-year open pit, heap leach mining operation. Using a gold price of US $1,800 per ounce, the project has a pre-tax net present value discounted at 5% (“NPV5”) of US $71.4M (US $47.7M post-tax) and an Internal Rate of Return (“IRR”) of 59% pre-tax (45% post-tax). Using a gold price of US $2,000 per ounce, the project has a pre-tax NPV5 of US $116.8M (US $77M post-tax) and an IRR of 85% pre-tax (63% post-tax). 

The PEA was prepared in accordance with the requirements of National Instrument 43-101 by D.E.N.M. Engineering Ltd. and Micon International Limited with confirmation of the applicable resource estimates prepared by SRK Consulting (U.S.) Inc.
