Project

Minera Tres Valles is owned by two prominent partners, Sprott Resource Holdings (70%) and the Vecchiola Group (30%). These two businesses complement one another by both promoting the development of the project in an efficient and sustainable manner with high operational standards.

The Papomono ore body is composed of the Cumbres, Papomono (underground) and Norte mines. It is located in the Cárcamo and Chalinga (Manquehua) valleys. In the last valley mentioned, the Don Gabriel open-pit mine is also found.

The ore processing plant is in the Chuchiñí Valley in Quilmenco, which is located at a distance of 12 kilometers from the mines. The operations that exist in these three valleys give way to the name Minera Tres Valles.

History

Exploration campaigns at Minera Tres Valles started in 2005 with prospecting at the Papomono deposit. Subsequently, prospecting and exploration developed at Don Gabriel, leading to the formation of the Environmental Impact Study that was submitted to Chile’s Environmental Evaluation Service (SEA) in 2009. It was approved during that same year, and it includes the master plan of the operation.

Construction began in 2009, and continued throughout 2010, before starting operations in 2011. VALE was the only entity to own the Tres Valles project until 2013, which was when the Vecchiola group became the sole proprietor. Just 4 years later, in 2017, 70% of the company was acquired by Sprott Resource Holdings.

Sprott is a Canadian Company dedicated to investing in projects that are related to natural resources throughout the world.

Safety

Safety is a fundamental principle of our operation at Minera Tres Valles where we constantly aim to respect the lives of all those who are directly related to the project. We have therefore developed a management system that seeks to incorporate safety concepts in every aspect of the Company.

At Tres Valles, we ensure the active participation of our employees by working alongside the Joint Health and Safety Committee (JHSC) in order to strengthen their knowledge of safety material.

The JHSC at Minera Tres Valles develops preventative measures in the fields of safety management and occupational health. They even hold a gold category certification for their commitment to reinforcing our strong safety culture at the mine.

Human Care

The top priority at Minera Tres Valles is our people. We set our sights on hiring local workers, especially those coming from the surrounding communities.

This is evident as the majority of our workers are from the neighboring territory.

Tres Valles looks to promote employability skills through professional development and long-lasting relationships, which is shown by our very low turnover rate.

We also make sure to acknowledge our employees when their experiences show a strive for excellence at the workplace.
