It was listed on the TSX (under the symbol FAL.LV) and NYSE (FAL), and had revenue of US$6.9 billion in 2005. In August 2006, it was absorbed by Swiss-based mining company Xstrata, which had formerly been a major shareholder.
Falconbridge, named after the town Falconbridge, which in turn was named for a prominent "son", one Sir William Glenholme Falconbridge, High Court Judge whose father John Kennedy Falconbridge, had migrated to Ontario from Lisburn Ireland.
Falconbridge was an important player in the economic and commercial development of the northern region of Ontario Canada, particularly the communities in and around Sudbury.
