Mining could return to the island after some 60 years.
The Department of Economic Development is about to issue licences in four areas – Snaefell, Sartfell, Glen Rushen and Glen Crammag – to companies interested in carrying out initial prospecting.
DED development manager David Roberts said: ‘The early stages of a prospecting programme would likely involve the taking of soil and river samples which would be analysed for traces of minerals.’
He said an aerial geomagnetic survey would also be undertaken to identify the presence of minerals reserves.
Mr Roberts said: ‘It would be a matter for government to assess future activity.
‘If metals were found, and in quantities/ situations that made them viable to economically exploit, it would be necessary for the prospective miner to obtain planning permission.’
A mining licence, setting out the total mineral to be extracted, the rate of extraction and the financial agreement between the miner and government, would also be required.
When asked what measures would be taken to minimise the environmental impact of mining operations, he said a full environmental impact assessment would be carried out.
