In 2016, Dumas was contracted to undertake shaft sinking, engineering, and mine development at the Saucito Mine in Fresnillo, Zacatecas.
The project included extensive ramp and decline development, as well as the construction of twin ventilation shafts. Development scope covered more than 19,000 metres of lateral and ramp development, with Dumas achieving an average of 380 metres per month using a single fleet, and the capacity to exceed 700 metres with two. Dumas focused on training and integrating local employees, instilling both technical competence and a strong safety culture.
The Twin Ventilation Shaft Project included two 305-metre, 6.5-metre-diameter concrete-lined shafts, each equipped with modular headframes and winch/control house systems, enabling efficient mobilization and demobilization.
Scope of Work
- 20,000 metres of ramp and lateral development
- Two 305m x 6.5m diameter concrete-lined ventilation shafts
- Engineering, design, and shaft infrastructure installations
