One of the longest-serving employees of ASX-listed Perseus Mining, Elissa Brown, has resigned as CFO.

She joined the company as a financial controller in 2010 and will step down with effect from October 31.

She was promoted to the role of CFO in February 2013, and during her time with Perseus, the company states that Brown has been a key member of its senior management team and has “worked tirelessly” to successfully transition Perseus from a junior explorer into a multi-mine multi-jurisdictional gold company.

Lee-Anne de Bruin has been appointed to succeed Brown as CFO.

Perseus says De Bruin has an “impressive history” in senior finance roles in the resources sector, both in Australia and Africa and that she is well equipped for her new role.

Most recently, she served as the CFO of fellow West Africa-focussed gold miner Resolute Mining and, prior to that, she had roles with Newmont and BHP.

After a brief period of overlap with Brown, De Bruin will formally assume the CFO role by November 1.

Perseus CEO Jeff Quartermaine says it was with genuine regret that the company accepted Brown’s resignation, as she was an important member of the company’s senior executive team.

“However, we share her excitement about the next phase of her life as she and her partner are preparing to welcome a new member of their growing family. Brown’s contribution to Perseus over the last ten years has been immense and we sincerely thank her for the dedication to her role and her friendship.”

According to the miner, De Bruin’s arrival at Perseus is an exciting step forward for both her and the company.

Perseus states that it is poised to become a 500 000 oz/y gold producer from its three West Africa mines and, with De Bruin’s financial acumen to assist, it aims to continue along its growth path and establish Perseus as a reliable midtier gold producer.

“The experience that Lee-Anne brings to the senior executive team will be invaluable and we are looking forward to working with her as we continue our journey.”
