The company was founded by James Crotty, and was for a few years a fierce competitor with Mount Lyell. Geoffrey Blainey gives a description of the rivalry and final amalgamation in 'The Peaks of Lyell'. As Blainey points out, the North Mount Lyell workings eventually proved vital for the Mount Lyell Company.
The 1912 North Mount Lyell Disaster is also found in Blainey's work, but for decades later there were divergent and popular accounts from the official reports that followed.
The North Lyell locality (at which some of the workers killed in the disaster had addresses) was eventually overtaken by the Mount Lyell mine workings and ceased to exist. A rare photo of the locality is in Blaineys book.
