Former air corps engineer Pat Purcell (77) set up specialist mining equipment group Mincon on the banks of the Shannon in the 1970s. It was briefly famous when its equipment was used to rescue Chilean miners trapped underground in 2012.
The company floated on stockmarkets in 2013 but the share price is well under water. It has, however, risen from last year's lows. Clare's Purcell and his family own 58pc of the company, with a stake worth €80m. A €15m special dividend was shared out before the IPO.
