Our processes are sustainable due to our commitment to the environment.
Our areas of concern are communities, the environment, a circular economy and social well-being.
We strive to be agents of positive change, integrating sustainable practices in all our operations to contribute to long-term economic, environmental and social development, thus consolidating a mining industry that harmonizes with the current and future needs of our environment.

Circular Economy
Dumps in the site are deposits resulting from the historical accumulation of sterile material mixed with low-grade minerals which were not economically feasible to process at the time with conventional methods. The company applies innovative automated selective classification of minerals, known as ore sorting, process in which optical sensors identify particles with material remains and separate them from the sterile one generating a pre-concentrate product that is the basis of the leaching process in the Michilla mine site. With this innovative method we can create a pre-concentrated product which directly feeds the leaching process at the Michilla mining site, optimizing resources and promoting sustainable mining practices.

Filtered tailings
The tailings produced by the Tambo de Oro site are deposited in a solid form after having recovered 85% of the water in it. As a result of that, the operation has solid tailings, making it unnecessary to have tailings dam and the associated risks of affecting nearby communities. Together with eliminating the main dangers involved with tailing dams, it also significantly improves landscape.
The filtered, solid tailings are deposited in successive steps in which compacted land is incorporated making it physically stable and easier to naturally reincorporate the material to the land where it came from. The higher costs this entails are considered by the company as a commitment to have a safer operation with a smaller environmental footprint.

Waste management
Because waste management is a critical issue in our mine operations, we implement advanced waste management practices that not only comply with local and national regulations, but also reflects our commitment to humanized mining and long-term sustainability. Our plans include reduction at its source, reuse and valorization of residues, promoting a mining concept that is harmonical with the present and future need of our environment. We are continuously reviewing and improving our practices to ensure that our operations are carried out in a responsible and sustainable manner.

Minimum use of continental water in our processes
We are committed to maximizing the use of water, reducing it to the necessary minimum level. It is essential for us to ensure that none of our activities depend on the use of water rights, consequently demonstrating our commitment to a sustainable management of water resources and respect for the environment.

Climate change and carbon footprint
HMC is firmly committed to sustainability and innovation, continuously working to mitigate the impacts of climate change and advance in the adaptability of our business. We have focused, from the beginning, on carrying out sustainable operations using a model that does not utilize continental water. Today, 100% of the electricity that is used in our processes comes from non-conventional renewable energy sources. This approach not only reflects our commitment to excellence and environmental responsibility, but also towards the community and social well-being.

Biodiversity and Heritage
We are firmly committed to the conservation of biodiversity and natural resources in our operations, as well as to preserving the valuable cultural and archeological heritage in our area of influence.
To ensure the viability of our projects, we carry out Environmental Impact Studies and Statements in close collaboration with local communities and relevant authorities. This approach allows us to move towards more sustainable technologies, ensuring that our activities are environmentally friendly and contribute to the well-being of local communities.
