Grupo Minero Bonanza (Bonanza Mining Group) started in 1991 with a handful of engineers and teachers from the ESPOL Polytechnic University, with the purpose of facing technically and entrepreneurially the challenge of processing waste minerals in the Ponce Enriquez sector in Ecuador, implementing the Carbon-in-Pulp Cyanidation process. Since then, we have been permanently focused on achieving higher efficiency and profitability based on the development and application of efficient and clean technologies, making knowledge the basis of the growth of our companies. Grupo Minero Bonanza maintains operations in Ecuador, Colombia, Bolivia, and soon Peru, working in all phases of mining, caring for its collaborators, complying with regulations, protecting the environment, and cooperating with communities settled in mining areas.
