The mines at the "Buena Esperanza" region mine follow the rich ore veins faithfully. In the first phase of mining, underground work was carried out for the most part, and only in the last phase did they attempt to open-cast mining in a somewhat larger style.    The official statistics from 1869 speak for themselves: The Buena Esperanza was the most successful mine in the region. It produced more than the entire Chañarcillo district.

More than 42% of the fine silver of the Department Copiapó in 1869 was mined in the Esperanza Mine.  The efficiency was also impressive: 1269 kilograms of rock were processed on average per worker (per month) - during this period, 400 - 500 kilograms of quarried rock were normal: this figure shows a fairly high degree of mechanization of the mine and on very well planned and executed excavation methods.
