Plans have been submitted for a new underground pot-ash mine beneath the North Yorkshire moors.
The development would be close to Sneaton village, near Whitby.
More than one billion tonnes of the mineral polyhalite has been found - it would then be mined and turned into pot-ash fertiliser.
If the application is approved the project could create thousands of jobs for the local area.
Plans are expected to be put to public consultation.
