TORONTO - RNC Minerals says its president and chief executive has resigned effective immediately for personal reasons.

Mark Selby was appointed CEO in 2014, about four years after joining Royal Nickel Corp., as it was previously called, as senior vice-president business development.

Executive board chairman Paul Andre Huet has been appointed interim CEO.

Huet has more than 30 years of mining industry experience, including serving as president and CEO of Klondex Mines between 2012 and 2018.

RNC owns two gold mines in Western Australia and minority interests in a joint venture that owns the Dumont Nickel-Cobal project in Quebec and the Orford Mining Corp., a mineral explorer focused on underexplored areas of Northern Quebec.
