THE Dublin city councillor and former banker is financial director of Teknomining, a fledgling mining company launched on the London-quoted Plus Markets last Friday.
He began his career with Allied Irish Banks in 1977, working in Dublin, London and in New York. From 1984 he was associate director of AIB International Financial Services.
He set up Barrick Capital Corporation in 1992, an IFSC-based subsidiary of international mining firm Barrick Gold. He was general manager there until 1995.
In the late 1990s he was head of finance at Bankgesellschaft Berlin (Ireland). Its parent, a top German bank, famously had to be bailed out by the German exchequer to the tune of €2bn in 2001.
He was MD of north Dublin builder Jerry Beade's Greencastle Investments in the early 2000s. Ring has said his biggest business break came through a site he bought with Beade in Coolock, Dublin.
From a staunch Fianna Fail family, Ring was part of Bertie Ahern's St Luke's inner circle for several years, but when the Dublin north city boy was elected to that ward of Dublin City Council in 2009 it was as an independent, having not been selected to run for the party. He had run for Fianna Fail in 2004, losing narrowly.
Until last year he was a longstanding government appointee to the board of the IDA.
Teknomining's main focus is seeking copper, chromium and iron-ore deposits at sites in Turkey. Ring is also a shareholder and director of US Oil & Gas Plc, which has oil and gas interests in two sites in Nevada, America.
Married, with four sons, he plays five-a-side soccer and is a Chelsea season-ticket holder. He has a finance and accounting degree from DCU and a diploma in financial law from UCD.
