1 Introduction 1. 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.

2 Mineral Safeguarding Policy and Guidance 2.1 National Planning Policy Framework 2. 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.

2.2 Planning Practice Guidance 3. 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.

2.3 Cornwall Local Plan Policy 4. 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 adopted in November 2016. 5. 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 bulk transport, storage, handling and processing facilities and

sites shall be safeguarded from sterilisation by other forms of incompatible development.

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

resources and reserves;

aggregates (both primary and secondary), china clay,

building and ornamental stone (including roofing and



heritage materials) and metals (including relevant shafts and adits),

3. Mineral Safeguarding Areas will be identified for the following existing,

planned and potential mineral infrastructure;

key concrete batching and other products and roadstone coating,

storage, handling, processing and distribution of minerals, 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, storage, handling and processing for onward 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.

2.4 British Geological Survey (BGS) Safeguarding Guidance

6. 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.

3 Identification of Mineral Resources and

Infrastructure for Safeguarding 7. 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



3.1 Mineral Resource Information 8. 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 such as H G Dines1 and J H Trounson2.

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

3.2 Methodology for Assessing Mineral Resources and Infrastructure

9. 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. This approach is consistent with other authorities. 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

strategic development

Green Significant parts of the resource are likely to face

pressure from other strategic development

Amber Some parts of the resource may face pressure

10.It is also a requirement of the NPPF to safeguarding 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. 11.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

Criterion Code Judgement

Site is active Green Yes

Red No

Uses Green The site is used and is likely to be used in the

future

Amber The site has been used in the last 10 years

Red The site has not been used in the recent past

(10 years)

Location Green The site is located adjacent to the Strategic

Road Network (SRN), a rail network or sea route or quarry

Amber The site is located within 5km of the SRN, rail, sea with good access or within 5km of a quarry

Red The site is relatively inaccessible/remote

Potential conflict with

other forms of strategic development

Red The infrastructure is unaffected by pressure from other strategic development

Future potential

Green The site is likely to be used in the future

Amber Some evidence that the site could be used in

the future

Red Evidence suggests that the site is not suitable

for future uses

12.In the following safeguarding assessment, all criteria have been weighted equally and all score 1. 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.

3.3 Mineral Resources in Cornwall 13.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.

4 Safeguarding Assessments 4.1 Aggregates 14.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.

15.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.

16.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.

17.Step 2: The following sites are known to produce aggregate; these are listed in Table 3 Aggregate Resources in Cornwall, along with any unique properties/features.

18.The assessment criteria identified in Table 1 Mineral Resource

Assessment Criteria have been applied to the known aggregate resources and the results are set out in Table 4 Aggregate Mineral Resource Assessments. Given the abundance of primary aggregate

resources in Cornwall, it is considered appropriate to safeguard permitted proven high quality resources which can be delineated.

Penventon Quarry A27

SW 730 394

Revoked PP Granite Green







IDO permission for aggregate extraction which has been revoked in 19/4/16. Permission granted for residential development within the quarry.



4.2 Building and Heritage Stone 19.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.

20.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.

21.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.

22.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. 23.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.

24.Step 2: The following sites are known to produce aggregate; these are

listed in Table 5 Building Stone Resources in Cornwall, along with any

unique properties/features.

25.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.

26.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 Mineral Resource Assessments and Table 7 Heritage Mineral Resource

Assessments. It is considered appropriate to safeguard resources which are scarce, or have particular qualities.

Luxulyanite Granite Green







Disused quarries worked extensively in the 19th Century. Very distinctive coarse grained granite, which has a conspicuous ‘black and white’ texture. It would be difficult to satisfactorily restore a building built of Luxulyan granite (either from Tregarden (Luxulyan Quarry) or the quarries in the Luxulyan valley) with another kind of granite. It would be difficult to re-open quarries in the Luxulyan Valley, which produced a similar type of granite to Tregarden, such as Carbean, Colcerrow, Orchard, etc. Tregarden (Luxulyan) represents the only practical source for this type of granite for restoration work Currently the lower part of Tregarden (Luxulyan) quarry is flooded to a depth of about 6m. However, the upper benches are available and, at a cost, rubblestone could be extracted.

Castallack H5 Granite 10b

SW447 254 Dormant Granite Green







Granite used mainly for local buildings and monuments. Castellack Quarry produced significant amounts of stone judging by size of the quarries. Dormant permission. Quarry is overgrown and flooded.

Cataclews H6 Greenstones 1

SW873 762 Dormant Greenstone Amber







This valuable stone is one of the 'classic' building stones of Cornwall. It is used mainly for special features rather than whole buildings such as doorways, pillars, arches, fonts etc.

Cheesewring H7 Granite 8a

SX258 723 Dormant Granite Green







Large granite quarry immediately below Cheeswring Tor. This stone may be required where a close match with stone in an existing listed structure is needed. Otherwise, many other quarries in Cornwall could supply similar stone. This is a fairly ‘standard’ granite, typical silver-grey in colour and medium to coarse grained. Adjacent to Goldiggins (which has pp).

Gwendreath H8 Greenstones 13

SW734 169 PP Serpentine Green







Within serpentine pp area. Serpenitnie peridototites belonging to the Lizard Complex. When polished, shows a variegated dark green/dark red surface. This type favoured as ornamental stone. The harder dark green, almost black peridotite was favoured for building stone. Ornamental stone, rather than building material.

Herdbury H9 Sanstone 1c

SS242 083 Dormant Sandstone Green







Quarry assessed alongside Pigsdon and Cansford. Non-operational quarry. No extractive planning permissions. Mid to late Carboniferous sandstone. Sandstone greyish-blue in character but rapidly weather to buff/brown. Nature of sandstone makes them break into convenient sized blocks for building. PP for concrete batching plant.

Kestle H10 Slate 3c SX015 715 Dormant

Trevose slate Green






Significant parts of the resource are likely to face pressure from other strategic development 6

A large quarry which is now disused. The quarry is in Trevose slate which has been intruded by two dolerites with associated adinoles (a form of thermal metamorphism of the slates adjoining the dolerite). Dormant minerals permission. PP for inert waste disposal.

A complex of three large early 19th Century quarries on the southern slopes of Kit Hill. A complex of two large quarries on the northern side of the hill; the latter operated until 1955. There is also abundant

evidence all over the hill of early moorstone working. Standard non-porphyritic biotite granite

Lamorna H12 Granite 10a

SW452 243







The resource is unaffected by pressure from other strategic development 7 Very coarse grained biotite granite.

Newham H13 Elvan 2 SW830 437 None

Felsitic elvan Green





High quality and/or range of uses Amber

Some parts of the resource may face pressure from other strategic development 9

Newham Stone, an elvan is much used in Truro in 18th 19th C buildings, especially Lemon Street. The width of the face at the w. end of quarry suggests potential for substantial resources. Unique resource for listed buildings in Truro.

Penrice H14 Elvan 7 SX023 505









Not unlike Pentewan Stone. Weathers quite well, so could substitute where it is not going to have to match existing stone.

Pentewan H15 Elvan 1 SX025 475









The two Pentewan Quarries may be a unique source where colour/texture matching is critical as with listed buildings.

Sheffield H16 Granite 10c

SW454 268








Very coarse grained biotite granite. Similar to Castallack. Granite appears to have mainly been used for local buildings and monuments

St Kew H17 Elvan 9 SX015 768

No planning permission Elvan Green







Long narrow quarry that contains unique elvan stone. Eastern part of quarry very overgrown. Western part of quarry worked relatively recently and still used as depot for aggregates.

Tregonning Hill H18 Granite 9

SW606 293


High lithian mica granite Amber







Highly prized as a creamy coloured building stone which has a reputation for being easy to work, possibly because it was weakly kaolinized. Amber for mapping as although easily identified as granite, does no identify its grade or high lithium mica granite.

Tremore H19 Elvan 3 SX010 648

No planning permission Elvan Green







Two quarries either side of the valley. Overgrown. Elvan extends for over a km either side of the quarries. Tremore elvan is highly variable in appearance. Tremore elvan is sometimes pink, sometimes dark red, occasionally without oxide staining and pale grey.

Treveddoe H20 Elvan 4 SX149 693 None








Felisitic elvan. From distance appears similar to Pentwean stone in colour, but closer inspection shows crystals of quartz and feldspar. Lack of greisening may indicate this this elvan is not as durable as Pentewan Stone, but might substitute for it in some internal situations.

Watergate (Kingsand) H21 Elvan 10

SX433 509 None Rhyolite Green







A reddish not very hard stone which can be readily trimmed for use in rubble masonry. Older buildings in Kingsand and Cawsand suggest it is reasonably durable

Brannel H26 Elvan 5 SW953 519


Brannel Elvan Green







A pale buff stone with prominent bi-pyramidal quartz xenocrysts and occasional small phenocrysts of feldspar and dark mica. . In appearance this elvan is not unlike Pentewan Stone. There is no visible evidence of kaolinization.

Carn Grey H27 Granite4 SX034 551








Medium-grained granite, with a few scattered megacrysts of feldspar up to 40mm in length and quartz in rounded grains. Megacrysts of a dark mica (biotite) up to 10mm are also seen and seem to be characteristic of this granite.

Cathedral H28 Granite5 SW951 557


Granite (St Stephen Stone) 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.



4.3 China Clay 27.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.

28.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.

29.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%.

30.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).

31.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 Mineral Resource Assessments, 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.

4.4 Metals 32.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.

33.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. 34.As working metal resources has historically mainly taken place underground,

the Council worked with the Cornish Chamber of Mines and Minerals (CCMM) in 2006 to identify a list of strategically important shafts that could

potentially be considered for inclusion within mineral safeguarding areas. The study defined shafts at each site that would provide optimum access to any

remaining mineral resource capable of being extracted via existing underground mine workings, or feasible extensions to them. The remit of the study did not include the portals of drainage tunnels (adits) or the definition

of surface areas required for operational infrastructure, which would be needed to render development of the mineral resource viable. The scope and

results of the study are included in Appendix 1 of the Minerals Safeguarding DPD Evidence Report Metals.

35.Initial discussions with the BGS have indicated that safeguarding an area around strategic shafts is a suitable approach to metalliferous safeguarding.

Further information on the identification of strategically important shafts is available at www.cornwall.gov.uk

36.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 Mineral Resource Assessments.

4.5 Infrastructure 37.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.

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

as such could be located within industrial estates or construction sites.

40.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 Assessments.
