Sonoro Gold Corp. (TSX-V: SGO, FSE: 23SP) is the Canadian and German listed explorer and developer of the Cerro Caliche gold project in Mexico. This project has excellent infrastructure and is located in the immediate vicinity of Equinox Gold's well-known Mercedes Mine. Sonoro has the ambitious goal to install a low-cost heap leach plant for the production of a gold concentrate by early 2023 and with this to advance from developer to gold producer. The project's economic viability study, presented in September 2021, arrives at an expected mine life of seven years. During that time, 325,500 gold equivalent ounces are expected to be produced at an all-in sustaining cost (AISC) of $1,351 per ounce. Assuming a gold price of US$1,750 per ounce, the cost of building the processing plant and commencing mine production will be recouped in just 2.2 years. This is not a new task for the experienced management team, which has a strong stake in the company. It has decades of experience and the knowledge and skills necessary to build and operate a gold mine are in place.
