Firefly non-executive chairman Kevin Tomlinson said: "We are delighted to welcome Leanne to the board. Her wealth of experience in the copper sector and in financial management will enable her to contribute valuable insights as the company continues to progress towards becoming a copper and gold producer.

"Importantly, Leanne's appointment also strengthens the independence and gender diversity of the board, and appropriately enhances the board's composition following a period of rapid growth and Firefly's recent addition to the S&P/ASX 300 Index."

Firefly managing director Steve Parsons said: "Leanne will bring invaluable skills and experience to Firefly, particularly in the specialized area of copper marketing.

"With the copper-gold mineral resource continuing to grow at our Green Bay project and economic studies under way, Leanne is perfectly placed to help us prepare for what will be an increasingly important aspect of our business."
