The Managing Director of copper and gold developer EMED Mining has resigned with immediate effect, putting a dent in the shares on Thursday. Harry Anagnostaras-Adams, who co-founded the company in 2007, said he had stepped down as EMED moved into a different stage of its own development and required different management skills. Rod Halliday, currently Chief Executive Officer (CEO) of the company's EMED Tartessus subsidiary, has been appointed to the board as interim CEO of the whole group while a long-term successor is found. "I have taken the decision to step down to allow the appointment of a new CEO with a skill set more appropriate to the future role," he explained. He maintained that EMED was well placed as it approached the production stage.Shares in EMED were down 8.9% to 1.63p at 12:59 on Thursday.OH
