The Board of Kenmare Resources has appointed Peter McAleer as the new Chairman of the Company's Audit Committee.
This follows the removal of Mr Donal Kinsella from that position at a special meeting of the Board today.
Mr Kinsella was deputy chairman and a director of the company.
The board meeting follows a complaint made by company secretary Deirdre Corcoran against Mr Kinsella following an incident at Kenmare's Moma mine in Mozambique in May.
Mr McAleer joined Kenmare as a non-executive director in 2001.
After an investigation, chairman Charles Carvill sought and received a written apology from Mr Kinsella to Ms Corcoran, but he also asked Mr Kinsella to resign as chairman of the audit committee, where Ms Corcoran is secretary.
A statement said Mr Kinsella's voluntary resignation 'had not been forthcoming'.
