Biodiversity

Mitsui Kinzoku Group has been striving to conserve biodiversity in accordance with our Basic Environmental Policy.
Compania Minera Santa Luisa S.A, a mining company of Mitsui Kinzoku Group, has been operating the Huanzala mine in central Peru since 1968.
We have been striving to preserve the natural environment since the start of the operation, the first initiative of which was the improvement of the infrastructure around the mine.
The areas surrounding the Huanzala Mine and Pallca Mine, which are situated at an elevation of over 3,000 meters, are home to flora and fauna unique to that environment . Both mines have limited impact on the surface above the grounds as they practice underground mining. However, in order to minimize the effects of mine development and operations, we make sure to process the acidic water properly, and also conduct environmental baseline surveys and bio habitat surveys.
From 2019, due to the construction work to expand the tailings dam, we conduct the transplant of the wetland vegetation group (bofedal) at the Huanzala Mine, which is being performed in partnership with experts and affiliated government agencies in Peru. In addition, since 2018, we have been distributing pamphlets to the local residents on animal and plant protection, thereby providing information on initiatives being implemented toward the preservation of biodiversity.
