Minerals Safeguarding Development Plan Document

Cornwall has a wealth of mineral resources which have been exploited over the centuries. Its complex and diverse geology makes it distinctive. Current mineral extraction is focused on: china clay, aggregates (both primary and secondary), building stone and metals. Some of these minerals are of local importance for construction purposes, others, such as china clay, are of international importance.

There is a need to provide specific detailed information and policy on mineral safeguarding. The purpose of the Minerals Safeguarding Development Plan Document is to expand on the strategic policies and safeguard mineral resources for future use. Key aspects that the DPD cover includes: safeguarding china clay, aggregates, building stone and metals; and mineral infrastructure.

The Cornwall Minerals Safeguarding Development Plan Document was adopted by Cornwall Council on 4 December 2018.  The DPD now carries full weight as part of the policy framework for Cornwall. 

The Minerals Safeguarding DPD sets out areas of mineral resources and infrastructure to be safeguarded from other forms of development.
