Rehabilitation of Silvermines Historic Mine Sites


On the 4th August 2005 the Minister for Communication, Marine and Natural Resources, Mr. Noel Dempsey T.D. announced the provision of €10.6m funding by the State for the rehabilitation of the old mining sites at the Silvermines, Nenagh, Co. Tipperary.

North Tipperary County Council is responsible for having the rehabilitation scheme executed and the project will be carried out in accordance with the revised SRK Consulting Conceptual Plan for the Management and Rehabilitation of the Silvermines Area. 

Consultation Process

A Local Consultative Committee was selected at a public meeting on the 1st December, 2005 and comprises of representatives from the Silvermines Community and from individual sites in the project area.  Regular meetings are being held with this Group.

The Inter Agency Group (IAG) was re-established and held its first meeting in the Civic Offices on 17th February, 2006. This Group comprises representatives from the Environmental Protection Agency, the Health Services Executive, the Department of Communications, Marine and Natural Resources, the Department of Environment, Heritage and Local Government, the Food Safety Authority of Ireland, the Department of Agriculture and Fisheries, the Geological Survey of Ireland, the Central Fisheries Board, North Tipperary County Council and the local community.  It is envisaged that the expertise and experience of this group will play an important advisory role as the project is advanced and meetings will be held as required. 

Work Programme

Golder Associates Ireland was appointed Design Consultants for the project on 19th June, 2006.  It is anticipated that this major rehabilitation project will be phased over a three to four year period and that site work will commence in 2007. The sites where works will be carried out are Gortmore, Garryard, Shallee, Magcobar, Gorteenadiha and Ballygown. SRK Consultants (UK) Ltd. was appointed project consultants in Feb. 2009 to complete the Silvermines Rehabilitation Project.

Garryard Mine Waste management Facility (MWMF) An engineered mine waste facility at Garryard (behind rail track by the old Mogul buildings), EIS submitted to ABP 12th February 2010, NTCC is planning applicant. Planning granted in March 2012.

In the context of the current economic situation, funding for Dept. of Communications, Energy and Natural Resources capital projects, including the Silvermines project, was reduced and in consequence this necessitated a rephasing of previously anticipated elements of the project.

The Minister of State has agreed that the remediation works planned for Garryard will not proceed until such time as sufficient funds are in place to execute the full project to completion, and has agreed not to proceed with the application for a waste licence from the EPA  or take any action in respect to the granted planning permission until there is a real prospect of the project being able to proceed within the life of the licence.


Contracts will be put in place to provide for continued monitoring of the Silvermines sites to ensure no significant change in conditions occurs without detection.
