Specialist mining engineering group Mincon was set up by Clare man Purcell in 1977.
It raised €50m when floating on the Irish stock market just over a year ago. The company was best known for providing equipment that was used to rescue Chilean miners trapped underground in 2012. Former air corps cadet Purcell (76) and his family shared a €15m special dividend before the IPO. Shares have tumbled over the last year but the family’s 58pc stake is worth €66m.
