Lupin Mine
The Lupin Mine is located approximately 285 kilometers (km) southeast of Kugluktuk, in the Kitikmeot Region of Nunavut and is owned by Lupin Mines Incorporate (LMI), a wholly owned indirect subsidiary of Alkane Resources Ltd. It is an underground gold mine that was in operation from 1982 to 2005 with temporary suspensions of activities between January 1998 and April 2000, and again between August 2003 and March 2004. The mine resumed production in March 2004 until February 2005. From 2005 until 2019 the Site remained in Care and Maintenance. LMI continued active preparatory work and initiated year one of the active closure phase in Q1 of 2020. Active closure was paused in 2020 and re-entered Care and Maintenance status since. Active preparatory resumed in 2024 and 2025, and active closure is intended to restart in 2026.
