Langlois mine is a drain on resources and is currently on care and maintenance.
In 2019, Nyrstar put its Langlois zinc-copper mine on care and maintenance. The company said that rock conditions at the mine have deteriorated to the point that continued mining is not economical. |

The mining segment currently consists of Nyrstar Tennessee Mines (U.S.). To allow the company to focus on its core business, i.e. smelting, the Myra Falls and Langlois mines, in Canada, were transferred to Trafigura’s Mining Group in October 2020.

Summary:
Langlois sulphide zones are near vertical lenses comprised primarily of sphalerite and pyrite with lesser chalcopyrite and pyrrhotite. Galena and gold are found in low quantities. There is strong geological continuity of the mineralization as demonstrated in the extensive diamond drilling and underground development.
