Mining executive and non-executive director of Anglesey Mining plc Howard Miller died on 22 December after a short illness.
Mr Miller had been NED of Anglesey since 2001 and served as lead independent director from 2013 until his death.
He began his career as a lawyer in South Africa, rising to senior partner at Johannesburg law firm, Raphaely-Weiner.
Mr Miller and his family moved to London from where he built and led many mining and exploration companies across the globe.
Most recently, he was chairman and CEO of Avnel Gold Mining Ltd, which operated the Kalana gold mine in Mali, before he sold it to Endeavour Mining in 2017.
Previously, Mr Miller was president and CEO of Tahera Diamond Corporation, which developed the Jericho diamond mine in northern Canada, and earlier was CEO of Nelson Gold, operating the Jilau gold mine in Tajikistan.
He was also a founding director and shareholder of T Hoare & Company, a predecessor of Canaccord Securities.
In addition, from London, Mr Miller held various directorships and executive positions with mining and mineral exploration companies across Africa, Canada and Central Asia between 1988 and 1994.
On behalf of the Anglesey Mining’s board, chairman John Kearney said, “Howard had a wealth of knowledge and experience across all legal, financial and management areas, and provided wise counsel and sound advice to the Anglesey board and company management.
“We extend our sincere condolences to Howard’s wife, children and family.
“He will be sadly and fondly missed.”
