In 1991, Conroy Petroleum & Natural Resources P.l.c. acquired Atlantic Resources PLC, and on completion of the acquisition, the new enlarged entity changed its name to Arcon International Resources P.l.c.
In 1997, Arcon de-merged its hydrocarbon assets into a new company, Providence Resources P.l.c. and listed on the Exploration Securities Market (ESM) of the Irish Stock Exchange.
In 2005, Providence switched from ESM to the Irish Enterprise Exchange (IEX), now Enterprise Securities Market (ESM) and was also admitted to the Alternative Investment Market (AIM) in London.
