Sonoro Gold Provides Environmental Permit Update
VANCOUVER, Canada — Sonoro Gold Corp. (TSXV: SGO | OTCQB: SMOFF | FRA: 23SP) is excited to announce the latest progress regarding the Environmental Impact Statement, known as the Manifestación de Impacto Ambiental (“MIA”) for its Cerro Caliche gold project. This substantial step aims to improve the project's footprint while promoting enhanced social and environmental stewardship.
The Revised MIA Submission
The revised MIA was submitted to SEMARNAT, the Mexican federal permitting authority, leading to an optimized project that emphasizes Sonoro's dedication to responsible practices. This submission marks an important milestone as it replaces the earlier version submitted in May 2022, showcasing the company's unwavering commitment to meeting and exceeding environmental standards.
Kenneth MacLeod's Insights
Kenneth MacLeod, President and CEO of Sonoro, emphasized the significance of the MIA permitting process. He stated, "The rigorous technical and environmental studies involved over the years not only ensure compliance with Mexico’s stringent environmental regulations, but also demonstrate Sonoro's commitment to the local communities affected by our project." This approach underlines Sonoro's long-term vision of sustainability and corporate responsibility.
Core Project Features
The MIA outlines a comprehensive open-pit, heap leach mining operation, including essential components such as waste dumps, gold recovery facilities, and leach solution ponds. This thorough detail reflects the extensive planning documented in the Company's Preliminary Economic Assessment dated August 28, 2023.
Securing Rights for Cerro Caliche
In Mexico, the approval of an MIA is critical for mining construction and operations. Sonoro proudly holds 100% of the concession rights for the Cerro Caliche project. Recently, on July 4, 2025, the company announced its successful acquisition of full surface rights to the concessions and surrounding areas, reinforcing its operational foundation.
Understanding the Cerro Caliche Gold Project
The Cerro Caliche project spans an impressive 1,400 hectares and has revealed a promising low-sulphidation epithermal vein structure, with more than 25 gold mineralized zones identified. Despite only 30% of the site having undergone drilling and assay, the recent updated Mineral Resource Estimate (MRE) filed in March 2023 provides valuable insights based on an extensive 55,360 meters of drilled data.
Recent Economic Assessments
In a newfound Preliminary Economic Assessment filed in October 2023, the project showcased the potential viability of a sustainable 9-year open-pit heap leach mining operation. Assuming a gold price of US $1,800 per ounce, the after-tax net present value discounted at 5% (“NPV5”) stands at US $47.7 million, accompanied by an Internal Rate of Return (“IRR”) of 45%. Moreover, with a higher gold price of US $2,000 per ounce, the projected NPV5 rises to US $77 million, further illustrating the project's significant economic potential.
Commitment to Expert Oversight
The PEA was meticulously crafted in accordance with National Instrument 43-101 by D.E.N.M. Engineering Ltd. and Micon International Limited. Additionally, SRK Consulting (U.S.) Inc. verified the applicable resource estimates, ensuring the project's credibility and reliability.
