Cornwall Council is preparing a Minerals Safeguarding Development Plan Document (DPD) as part of the Local Plan. The DPD will identify those resources that are to be safeguarded from other forms of non-minerals development. The DPD supports the policies in the Cornwall Local Plan. 1.1 Purpose of this document 2. This technical report provides part of the background evidence to support the Minerals Safeguarding Development Plan Document. 3. It sets out the site profiles for the various mineral resources found within Cornwall and how those resources have been assessed to define the Mineral Safeguarding Areas. 4. The report is divided into six sections; Aggregates Building Stone China Clay Heritage Materials Metals Infrastructure 2 Buffer zones 5. The Mineral Safeguarding Areas each have different buffer zones around them; 500m around aggregates, 250m around building stone, 100m around heritage material, 250m around china clay and 500m around the principal metal shafts and 250m around secondary shafts. For infrastructure sites the safeguarding area extends around the site boundary.

The Mineral Site Profiles evidence document should be read in conjunction with the Minerals Resource and Infrastructure Assessment evidence Mineral Site Profiles Minerals Safeguarding DPD Evidence Report Submission June 2017 3 document. This document has assessed each of the sites outlined in this document for possible inclusion as a Mineral Safeguarding Area. The overall score for each assessment is provided in each site profile. However, the Mineral Resource and Infrastructure Assessment document provides a full overview of the scoring and criteria used to assesses each site. These criteria included the scarcity of the resource, the ability to identify the resource on geological mapping, viability, the quality of the resource and the potential conflicts with other forms of development. 4 Evidence In defining the Mineral Safeguarding Areas various sources of information have been used. These sources of information are set out below and include information from the British Geological Survey, industry knowledge and other publications. In addition, regard has been paid to the National Planning Policy Framework (NPPF) and Planning Practice Guidance Notes (PPG). The British Geological Society ‘Mineral resource information for development plans’1 as well as their Mineral Factsheets has been used along with information gathered for the adopted Cornwall Minerals Local Plan and mineral industry knowledge. Each year, officers carry out a schedule of visits to both active and dormant minerals sites. As part of this, a report for each site is produced and the information within these reports have been used in the production of the site profiles. These site visit reports are available on the councils website https://www.cornwall.gov.uk/environment-and- planning/planning/minerals-waste-and-renewable-energy/ A planning history search has been carried out for each of the site profiles. Information from the online planning register http://planning.cornwall.gov.uk/online-applications/ has been used. The Sustainable Use of High Specification Aggregates for skid resistant road surfacing in England, Capita Symonds Ltd report. The following has been used to assess Metalliferous sites as well as information from the Metals Evidence report and associated Appendix 1 Mine Shafts Study.

The small hamlet of Polyphant is located to the north west of the quarry and there are no immediate residential neighbours. The main quarry void is not currently being worked and remains filled with water. There are currently limited amounts of stock piled material located on site that are sold and exported whenever possible. Safeguarding Site is not currently working but has produced significant amounts of assessment aggregate. PSV is 57-60. Site is potentially worked out. PSV resource cannot information: be defined on geological mapping.

It is accessed from the A39 by a shared road which also provides access to the neighbouring concrete plant and a farm. The quarry has been dormant for many years and recently re-opened. Works continue to take place on site to ascertain what reserves currently exist and methods for their extraction. Safeguarding Recent tests indicate potentially high PSV resource. PSV resource cannot be assessment defined on geological mapping. Site has been dormant for many years. The information: extraction of stone is currently taking place in a westerly direction in order to determine the level of reserves available. No products currently being produced.
