Sonoro Gold Gets TSXV Approval for Cerro Caliche Surface Rights

Canada-based mining company Sonoro Gold announced it has received final acceptance from the TSX Venture Exchange (TSXV) for the surface rights lease agreement for its Cerro Caliche Gold Project in Sonora. The company stated this step, along with its recently updated Environmental Impact Assessment (EIA), is key to advancing the project. 

With the approval, Sonoro Gold now controls 100% of the surface and mineral rights for the project area, which includes exclusive access for exploration, development, and mining infrastructure construction.

The company also announced it has completed the cash payments of US$3.1 million to the lessor, satisfying the financial obligations for the first year of the agreement. Sonoro will also issue 5 million common shares at a deemed price of C$0.15 (US$0.11) per share as part of the consideration.

Funding for the Year 1 cash payment was financed through US$2.9 million in unsecured loans from company directors. The company noted that the loans constitute a "related party transaction" and that it is relying on standard exemptions from formal valuation and minority shareholder approval requirements under Canadian securities regulations.

The TSXV acceptance comes over a month after the company announced it had secured the rights on July 04, 2025. According to Sonoro Gold, the agreement covers a 3,908ha area, which includes the 1,350ha covering the company's 15 contiguous mining concessions. The lease agreement has an initial term of 12.5 years with an option to renew for an additional 12.5 years, as reported by MBN. The company said the payment terms for the first three years include US$15.625 million in total cash payments, which includes an initial US$1 million payment that has already been made, plus a one-time issuance of 5 million company shares.

Sonoro Gold Updates Cerro Caliche’s MIA 

Sonoro Gold also provided an update on the status of its EIA for the Cerro Caliche project to the Ministry of Environment and Natural Resources (SEMARNAT) to optimize the project's footprint and enhance its social and environmental stewardship.

According to Sonoro Gold, the revised EIA was submitted in February 2025 and replaces the May 2022 version. Among the main changes were the enhancement of the mine plan, and additional environmental baseline studies, as well as socio-economic assessments.

The company noted that the EIA permitting process has involved years of extensive technical studies. “These ongoing assessments are carried out not only to ensure the project is meeting Mexico’s strict environmental requirements, but they also reflect Sonoro Gold’s commitment to the local community,” noted Kenneth MacLeod, President and CEO, Sonoro Gold.
