Rialto managing director Jeff Schrull plans to step down from the position. He has informed the board that he intends to relocate to Perth, Western Australia, from the company's current base of operations in London by mid-2013, a news release said.

The decision by Schrull is further to a number of ongoing Rialto board discussions on strategy, near term work program, board composition, and succession planning that have taken place over recent months.

As a result of Schrull’s decision, the board will start a process to appoint a replacement. In the interim, Schrull has confirmed his commitment to progressing a number of key initiatives within Rialto,  including the 2013 CI-202 exploration and appraisal drilling program, matters relating to the potential farm-out of CI-202, and early stage planning for any Gazelle development, according to the release. Up until his departure, Schrull will remain on the board and work closely with management to continue with ongoing business growth and operations to ensure a smooth transition.
