Galantas Gold Corporation (AIM:GAL) shares fell as much as 12% after chair Róisín Magee resigned from the board to take a senior role in private equity.
The departure is effective immediately, leaving David Cather, an existing director, to serve as interim chair while the board considers a permanent appointment.
The board now comprises five directors following the change.
President and CEO Mario Stifano said: "On behalf of the entire Board, I want to thank Róisín for her valued contributions to Galantas and wish her well in her future endeavours."
Galantas closed Wednesday's session at 23p, marking an 8% loss for the day.
