Introduction This evidence report supports the Minerals Safeguarding Development Plan Document (DPD). It sets out the assessment criteria used to consider the

various mineral resources found within Cornwall and their potential for safeguarding.

Mineral Safeguarding Policy and Guidance

National Planning Policy Framework The National Planning Policy Framework (NPPF) states that mineral

safeguarding areas be defined for local and nationally important mineral resources as well as existing, planned and potential transport and other mineral infrastructure. The NPPF defines mineral safeguarding areas (MSAs)

as “those areas designated by mineral planning authorities which covers known deposits of minerals which are desired to be kept safeguarded from

unnecessary sterilisation by non-mineral development” (Annex 2, Page 54 NPPF). The NPPF does make it clear that any designated MSA does not create a presumption in favour of mineral working in those areas.

Planning Practice Guidance The Planning Practice Guidance (PPG) on ‘Minerals’ was published in October 2014 and provides further information and guidance on the NPPF. The Guidance advocates a systematic approach to safeguarding of mineral

resources; use the best available information on the location of mineral resources; consult the mineral industry, local communities and other

relevant interests; set out Mineral Safeguarding Areas on the policies map; adopt clear development management policies which set out how proposals

for non-minerals development in Mineral Safeguarding Areas will be managed.

Cornwall Local Plan Policy The Cornwall Local Plan provides the strategic policy framework for the

Minerals Safeguarding DPD, setting out the principle of mineral safeguarding. The Local Plan was examined in 2015/16 and it is anticipated that the Local Plan will be adopted towards the end of 2016.

Policy 18 sets out the strategic principles for safeguarding mineral resources

and infrastructure.

Policy 18: Minerals Safeguarding 1. Important mineral resources and reserves and existing, planned and

potential associated bulk transport, storage, handling and processing

facilities and site shall be safeguarded from sterilisation by other forms of incompatible development.

2. Mineral Safeguarding Areas will be identified for the following mineral

resources and reserves;

a. Aggregates (both primary and secondary), b. China clay,


November 2016.

c. Building and ornamental stone (including roofing and heritage materials) and

d. Metals (including relevant shafts and adits)

3. Mineral Safeguarding Areas will be identified for the following existing, planned and potential mineral infrastructure; a. Key concrete batching and other products and roadstone coating,

b. Storage, handling, processing and distribution of minerals substitute, recycled and secondary aggregate,

c. The bulk transport of minerals by rail, sea (ports) or haul roads. The Cornwall Minerals Safeguarding Development Plan will develop detailed

policy and identify sites for safeguarding minerals, mineral resources and associated facilities for transport, by rail or sea. Key sites used for the

batching / manufacture of concrete products and coated materials will also be identified for safeguarding as well as sites for processing and the distribution of substitute recycled and secondary aggregate materials. Policy

will also be developed to encourage prior extraction where appropriate.

BGS Safeguarding Guidance In 2011 the British Geological Survey produced a guidance document on mineral safeguarding

(http://www.bgs.ac.uk/mineralsuk/planning/legislation/home.html under Mineral Safeguarding). This document set out a step-by-step guide to

identifying and defining mineral resources which would be appropriate for safeguarding.

Step 1 involves the identification of the best geological and mineral resource information.

Step 2 decide which mineral resources are to be safeguarded and the physical extent of the safeguarding area.

Step 3 consult on the scope of mineral safeguarding areas.

Step 4 decide on the approach to safeguarding within planning policy.

Step 5 include effective development management policies within DPDs.

Step 6 is not relevant to Cornwall as it refers to two-tier authorities and step 7 relates to implementation of mineral safeguarding.

Identification of Mineral Resources and

Infrastructure for Safeguarding To assess the main mineral resources in Cornwall, the step-by-step process from the BGS ‘Mineral Safeguarding in England: Good Practice Advice’ has been applied.

http://www.bgs.ac.uk/mineralsuk/planning/legislation/home.html


November 2016.

Mineral Resource Information To aid the analysis of mineral resources in Cornwall there are various sources of information; these include BGS Mineral Factsheet, BGS ‘Mineral resource information for development plans’, industry knowledge and other

publications. In addition, regard has been paid to the NPPF and PPG.

Methodology for Assessing Mineral Resources and Infrastructure The BGS guidance step 2 requires the identification of mineral resources that should be safeguarded. In order to assess the mineral resources of

Cornwall, a criteria based approach has been developed. The following criterion and ‘traffic light’ scoring system has been used to assess the mineral resources, as set out in Table 1 Mineral Resource Assessment

Criteria. Table 1 Mineral Resource Assessment Criteria

Criterion Code Judgement

other forms of strategic

development

Amber Some parts of the resource may face pressure from other strategic development

Red The resource is unaffected by pressure from other strategic development

The application of the criteria and the assessments enable the appropriate

level of mineral resource and infrastructure safeguarding to ensure mineral use for the future.

It is also a requirement of the NPPF to safeguard existing, planned and potential rail heads, rail links to quarries, wharfage and associated storage,

handling and processing facilities for the bulk transport by rail, sea or inland waterways of minerals including recycled, secondary and marine-dredged

materials; and existing, planned and potential sites for concrete batching, the manufacture of coated materials, other concrete products and the handling, processing and distribution of substitute, recycled and secondary

aggregate material.

A different set of assessment criteria has been developed to assess the safeguarding potential of the known mineral infrastructure. The following criterion and ‘traffic light’ scoring system has been used to assess the

mineral infrastructure, as set out in Table 2 Mineral Infrastructure Assessment Criteria.

Table 2 Mineral Infrastructure Assessment Criteria

Mineral Resources in Cornwall The following mineral resource types in Cornwall have been assessed;

aggregates, building stone including heritage material, china clay and metals. The following section sets out the safeguarding assessment for each of these mineral sectors.

Safeguarding Assessments

Aggregates Step 1: The National Planning Policy Framework (NPPF) states that mineral safeguarding areas should be defined and appropriate policies adopted so that known location of specific mineral resources of local and national

importance are not needlessly sterilised. Mineral planning authorities should plan for a steady and adequate supply of aggregates.

The BGS Factsheet on construction aggregates states that the suitability of

an aggregate for a particular purpose depends on its physical, mechanical and in some applications chemical/mineralogical properties.

The BGS Report ‘Mineral resource information for development plans’ states that granites are the most extensive igneous rocks in Cornwall and account

for a major proportion of primary crushed rock output. Granite aggregates are commonly used as coarse and fine concreting aggregate, asphalt material and unbound road material. In some cases granite has a

sufficiently high polished stone value (PSV) to be used in less demanding road surfacing applications. Granites vary considerably in texture and

appearance and there is considerable variation in rock strength. BGS data suggests that strength and PSV are independent of granite variety and texture and instead reflect local variations in weathering and secondary

alteration. Therefore it is difficult to identify any high quality resources. Basic igneous rocks, such as basalt, dolerite, gabbro and picrite are less

extensive than granites. However, these types of stone are used in coarse and fine concreting aggregate, asphalt material and unbound road aggregate. Sandstones occur within the Devonian and Carboniferous

formation in north and mid-Cornwall around Bude and east and central Cornwall. The presence of interbedded shales reduces the aggregate

potential of the resource. There are limited resources of primary sand and gravel in Cornwall. Small outcrops of Tertiary and Quaternary sediments, such as those or Crousa Downs on the Lizard and around St Agnes Head

have been worked. A small deposit of alluvial sand was previously worked at Trewint Marsh on the edge of Bodmin Moor; however, this resource is

worked out. Further information on the level of aggregate production is available in the annual Local Aggregate Assessment.

Building and Heritage Stone Step 1: The National Planning Policy Framework (NPPF) states that mineral safeguarding areas should be defined and appropriate policies adopted so that known location of specific mineral resources of local and national

importance are not needlessly sterilised. The NPPF also states that Mineral Planning Authorities should consider how to meet any demand for small-

scale extraction of building stone at, or close to, relic quarries needed for the repair of heritage assets.

The BGS Mineral Factsheet: Building and roofing stone states that building and roofing stone, are naturally occurring rocks of igneous, sedimentary or

metamorphic origin which are sufficiently consolidated to enable them to be cut, shaped or split into blocks or slabs.

BGS report ‘Mineral resource information for development plans’ says that granite occurs in four large ‘plutons’ at Land’s End, Carnmenellis, St Austell

and Bodmin Moor. In addition there are a number of smaller outcrops occurring throughout the county. There is considerable variation in the appearance of granite from one location to another, from fine-grained types

to coarse-grained granite with large individual feldspar crystals exceeding 10cm in length.

Basic igneous rocks such as basalt, dolerite, gabbro and picrite occur within the Devonian and Lower Carboniferous slate and sandstone. There is

considerable variation in lithology and technical properties between these basic igneous rocks. Serpentine occurs on the Lizard and on a restricted

sale in East Cornwall; it is highly coloured and soft and is used for ornamental purposes. However, it has been used in the past as a building material. In Cornwall there are considerable volumes of sandstone,

particularly in the north and east of the County. Despite extensive resources, limited amounts of sandstone are produced in Cornwall, perhaps

reflecting the cost of working the resource. A few smaller quarries extract sandstone for building materials alongside their main aggregate extraction.

Slates underlie much of Cornwall and are commonly interbedded with coarser-grained siltstone and sandstone. The slates are variable in nature

and colour ranging from dark to light grey with green and red hues. Slates which can be split are used for roofing but their occurrence is more

restricted. Cornwall is an important source of roofing slate, including Delabole slate noted for its distinctive silvery grey colour. Elsewhere operations are small-scale mainly producing rustic slate, commonly used for

paving, cladding, walling and fireplaces.

There are many quarries throughout Cornwall, which were used for local building projects and are now redundant. These sites could contain a

valuable resource which could contribute to local distinctiveness and heritage projects. In 2006, a study was commissioned by Cornwall County

Council to consider the old disused quarries in Cornwall. This study

identified those quarries which have the potential to be used for heritage projects and restoration. Quarries which scored 6 or above in the initial

study were then considered through the safeguarding assessment process. Further information is available www.cornwall.gov.uk/mineralsdpd. The assessment criteria identified in Table 1 Mineral Resource Assessment

Criteria have been applied to the known building stone resources and the

results are set out in Table 6 Building Stone Safeguarding Assessment and

Table 7 Heritage Quarry Safeguarding Assessment. It is considered appropriate to safeguard resources which are scarce, or have particular

qualities.

SW951 557 None Granite Amber







This is a unique stone type. The main china stone area yields a pale coloured (leucocratic) low iron granite with Li-mica replacing biotite, normally containing (when fresh) some tourmaline, topaz and fluorite. Usually, but not always, non-porphyritic.

China Clay Step 1: The National Planning Policy Framework (NPPF) states that mineral safeguarding areas should be defined and appropriate policies adopted so that known location of specific mineral resources of local and national

importance are not needlessly sterilised.

China clay is scarce nationally; resources are confined to the granites of South West England and Cornwall accounts for some 90% of total UK production. Historically china clay production has been based principally on

the central and western parts of the St Austell granite and on the south-western margin of Dartmoor.

The properties of the china clay deposits vary both within and between puts and blending to achieve consistency is critically important Due to the

presence of hard, unaltered granite and quartz/tourmaline veins overall recoveries of china clay may be as low as 10%.

The BGS has identified two classes of china clay resource; these are (i) measured and indicated resources (those resources which are known to

occur and coincide with current production areas where detailed exploration and evaluation has been undertaken) and (ii) inferred resources (those

areas where the industry believe china clay deposits may occur including previously worked areas but there are no current plans to develop these resources).

Step 2: The assessment criteria identified in Table 1 Mineral Resource

Assessment Criteria have been applied to the known ‘measured and indicated’ and ‘inferred’ china clay resources and the results are set out in Table 8 China Clay Safeguarding Assessment, these are set out by

Operational Area (a means of breaking down the mineral planning permission that covers the extent of the St Austell China Clay area). It is

felt that, in discussion with the industry, it is possible to safeguard measured/indicated and inferred resources which are considered to be

economically important.

Metals Step 1: The National Planning Policy Framework (NPPF) states that mineral safeguarding areas should be defined and appropriate policies adopted so that known location of specific mineral resources of local and national

importance are not needlessly sterilised.

The BGS ‘Mineral resource information for development plans’ has identified zones of intense hydrothermal vein mineralization and zones of scattered stratiform vein and stratiform mineralization in certain horizons within the

slate, sandstone and basic igneous rocks throughout Cornwall that are enriched in metals. These include veins and stratiform deposits that are

unrelated to the granites and their thermal influence, which cover broad areas across the County and do not appear give an indication of whether there is a quality of resource of such form quality and quantity that has

reasonable prospect for eventual economic extraction. The principal metallic ores extracted in the County have been tin, copper and iron. The veins

within and close to the granites mostly carry tin, in places with tungsten and arsenic. In some areas, for example around Gunnislake, the veins are noted for their polymetallic character.

As working metal resources mainly takes place underground, the Council

has worked with the Cornish Chamber of Mines and Minerals (CCMM) to identify a list of strategically important shafts that could potentially be considered for safeguarding. Initial discussions with the BGS have indicated

that this is a suitable approach to metalliferous safeguarding. Further information on the identification of strategically important shafts is available

at www.cornwall.gov.uk

Step 2: The assessment criteria identified in Table 1 Mineral Resource

Assessment Criteria have been applied to the known metalliferous mining areas and shafts identified by CCMM and the results are set out in Table 9

Metal Safeguarding Assessment.

Some parts of the resource may face pressure from other strategic development Field Shaft

Infrastructure The requirement of the NPPF can be divided into two main categories; infrastructure associated with the transportation of minerals and infrastructure associated with the processing of minerals into other

products.

The potential locations of rail and sea facilities are more limited and less flexible. The following mineral transport sites have been assessed:

Burngullow rail siding

Dean Quarry Wharf Fowey Docks

Lostwithiel to Fowey railway Methrose siding Par Docks

Par Docks to Fowey Docks haul road Parkandillack/Treviscoe rail siding

Parkandillack branch line Rocks rail siding West of England Quarry Wharf

To some extent many of the mineral processing facilities are ‘footloose’ and

as such could be located within industrial estates or construction sites. However, known locations of minerals transport and processing

infrastructure have been assessed using the criteria set out in Table 2 Mineral Infrastructure Assessment Criteria. The results are show in Table 10

Mineral Infrastructure Safeguarding Assessment.
