Metals miner Mandalay Resources Corp (TSE:MND) said chief operating officer Dominic Duffy has become the group's chief executive, after Dr Mark Sander resigned.
Duffy has 20 years' technical and operational management experience, having worked at numerous operations throughout Australia and Latin America.
Producer Mandalay, which has mines in Australia and Sweden, also noted that Sander was withdrawing his nomination for election to the board at the firm's AGM on May 16 this year.
"I want to thank Dr. Sander for his many years of service to Mandalay and his critical role as a founder of the company," Bradford Mills, Mandalay's chairman told investors.
"Mark has helped the company weather the operational crisis triggered by the Cerro Bayo accident and positioned the company to grow from its base of existing operations.
"I am very pleased to welcome Dominic Duffy to the role of president and chief executive.
"Dominic has demonstrated his commitment to delivering efficient, low-cost operations, which I believe is a critical next step for Mandalay and a key objective for the company."
Duffy successfully restarted Cerro Bayo after its acquisition from Coeur d'Alene Mines in 2010 and has been the group's chief operating officer since 2013.
