Mining Methods

  • Bench & Fill
  • Cut & Fill

Summary:

Saucito is an underground mine with a shaft approximately of 1000m depth. There are three types of veins Wide (> 2.5 mts), Medium (1.5-2.5 mts) and Narrow (< 1.5 mts) in Saucito. Bench & FIll and Cut & Fill methods are used for mining operations.

In 2022, the deepening of the Jarillas shaft, including horizontal development continued; projects to improve ventilation and pumping progressed as expected.

The project to deepen the Jarillas shaft from 630metres to 1,000 metres advanced an additional 40 metres, with further progress made in horizontal development and supporting infrastructure. The timeline of this project remains unchanged with completion expected by 2025.
