SONORO GOLD PROVIDES AN UPDATE ON THE ENVIRONMENTAL PERMIT (MIA)
FOR THE CERRO CALICHE GOLD PROJECT
VANCOUVER, Canada, July 9, 2025 – Sonoro Gold Corp. (TSXV: SGO | OTCQB: SMOFF | FRA: 23SP)
(“Sonoro” or the “Company”) is pleased to provide an update on the status of the Environmental Impact
Statement, or Manifestacion de Impacto Ambiental (“MIA”) for its Cerro Caliche gold project in Sonora,
Mexico. The Company has submited a revised MIA to the Mexican federal permi�ng authority, Secretaria
de Medio Ambiente y Recursos Naturales (“SEMARNAT”) to op�mize the project’s footprint and enhance
social and environmental stewardship.
The revised MIA was ini�ally submited in February 2025 and supersedes the prior MIA submited in May
2022. Revisions to the MIA, including enhancing the mine plan and undertaking addi�onal environmental
baseline studie s and socio -economic assessments , reflect the Company’s commitment to bring Cerro
Caliche into produc�on while ensuring the project meets the highest social and environmental standards.
Kenneth MacLeod, Sonoro’s President and CEO, commented, “The MIA permitting process for the Cerro
Caliche project has involved years of extensive technical and environmental 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’s commitment to the local community.”
The MIA details an open-pit, heap leach mining opera�on including waste dumps, crushing facili�es, heap
leach pad, leach solu�on ponds, gold recovery facili�es, haul roads, building structures and infrastructure
as proposed in the Company’s Preliminary Economic Assessment dated August 28, 2023.
Mining construc�on and opera�onal ac�vi�es in Mexico require an approved MIA, as well as ownership
of concessions and surface rights. The Company holds 100% of the concession rights for the Cerro Caliche
project and on July 4, 2025, the Company announced that it had secured 100% of the surface rights to the
Cerro Caliche concessions and surrounding areas.
About the Cerro Caliche Gold Project
Exploration to date at the 1,400-hectare property confirms a broadly mineralized low-sulphidation
epithermal vein structure and over 25 northwest-trending gold mineralized zones along trend and near
surface. With only 30% of the property’s identified mineralized zones drilled and assayed, the Company
filed an updated Mineral Resource Estimate (MRE) in March 2023 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, the Company filed a new Preliminary Economic Assessment (PEA) demonstrating the
potential viability of a 9-year open pit, heap leach mining operation. Using a gold price of US $1,800 per
ounce, the project has an after-tax net present value discounted at 5% (“NPV5”) of US $47.7M and an
Internal Rate of Return (“IRR”) of 45%. Using a gold price of US $2,000 per ounce, the project has an after-
tax NPV5 of US $77M and an IRR of 63%.
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.
