Ayacucho, Peru: extension of an elevator system to transport personnel, ore, waste rock and equipment within the Sotrami mine.

Sotrami mine employs 600 people and has been part of the Swiss Better Gold Initiative since 2013.

Sotrami is an underground mine, currently including 21 levels. In 2019, Sotrami initiated the construction of an elevator system, named the Pique Salvador with the capacities of carrying 18 people. In a first phase, the Pique reached working level 12. It has been operating since 2021 to safely transport personnel and equipment from and to the underground working galleries, as well as to lift ore and waste rock to the surface.

To improve the working and safety conditions on all the mine levels, the Pique Salvador needed to be extended. This extension was supported by the Swiss Better Gold Fund.
