Tara Mines could get a tax refund of just less than £60 million (€76 million) from the Exchequer if the High Court upholds a finding by the Revenue Appeals Commissioners that all the company's above-ground activities at its Navan mine constituted a manufacturing rather than a mining process.

The money sought by Tara relates to corporation tax assessments for January 1st, 1978, to December 31st, 1988, and already paid to the Revenue Commissioners.
