Labrador Iron Mines Holdings Limited (LIM) is a Canadian mining company that operates iron ore mines in the Labrador Trough region of Quebec and Newfoundland and Labrador. The company was founded in 2007 and is headquartered in Toronto, Ontario.

LIM's primary focus is on the development of its two iron ore deposits, the James Mine and the Redmond Mine, which are located in the Labrador Trough. The James Mine is located near the town of Schefferville, Quebec, while the Redmond Mine is located near the town of Wabush, Newfoundland and Labrador.

The company's operations are supported by a 50-kilometer rail line that connects the mines to the port of Sept-Îles, Quebec, where the iron ore is shipped to customers around the world. LIM has a long-term off-take agreement with Tata Steel Minerals Canada for the sale of its iron ore.

LIM has faced challenges in recent years due to the decline in iron ore prices and the closure of its operations in 2014. However, the company has continued to explore opportunities to restart its operations and has completed a feasibility study for the James Mine. LIM is also exploring the potential for new iron ore deposits in the Labrador Trough region.
