A scoping request has been made to extract more gravel from Harden Quarry at Biddlestone.
At the January Rothbury Parish Council meeting, Coun Steven Bridgett announced that the request had been made by Tarmac, which owns the site, to extract another 1.1million tonnes of rock over the next 15 years as well as deepen the quarry, within the original footprint.
Mineral extraction at Harden Quarry dates back to the 1930s, with subsequent modern permissions granted in 1967, 1979 and 1997.
If the new application is given approval it will see quarrying continue at the site until 2029.
The application also seeks permission to split the southern face of the site to remedy potential instability.
Coun Bridgett told the parish council that he was in support of the application.
He said that Tarmac has made a significant contribution to the surrounding villages, in particularly Netherton.
The request is currently at the scoping stage and no formal planning permission has yet been sought.
If an application is put in, it will go out to consultation before any decision is made by planning officers at County Hall.
