Who are Cornwall Resources Limited? 

Cornwall Resources Limited (“CRL”) are an exploration and resource development company based in Kelly Bray, Cornwall, who since 2016 have been focused on the development of the Redmoor Tungsten-Tin-Copper deposit and further exploration for other critical metal deposits that are needed to support the UK’s transition to a Net-Zero economy. 

CRL has an existing 23km² mineral rights agreement with Redmoor Minerals Limited covering the historic parish boundaries of Callington and South Hill, in east Cornwall.

Cornwall Resources are a wholly owned subsidiary of Strategic Minerals Plc (Strategic Minerals Plc - mining producer and explorer)

What activities has CRL undertaken?

CRL is currently developing the Redmoor Tungsten-Tin-Copper deposit, in Kelly Bray, which through its previous exploration drilling and related activities, identified an underground, inferred Mineral Resource Estimate of 11.7 million tons @ 1.17% Tin equivalent, composed of high-grade zones of Tungsten-Tin-Copper mineralisation. 

CRL are actively reviewing and studying all historical drill core, with the objective of identifying further mineralisation outside of the current resource and outlining targets for future drilling programs, which will aim to increase the resource size and confidence and take the project from Scoping Study stage to Pre-Feasibility stage.

CRL provided Redmoor as a field site for the acquisition of new geochemical and geophysical data and the development of geological expertise (in conjunction with Camborne School of Mones) as part of the Deep Digital Cornwall project. This program consisted of the collection of 2,186 soil samples, geophysical surveys and other field-based studies across the Redmoor license area. 

What is the Tamar Valley license Area?

The Tamar Valley License Area is a land package of c.64km² that encompasses Mineral Rights owned and held by The Duchy of Cornwall.



This license is the first of its kind to be awarded, in modern times, to a resource company by The Duchy of Cornwall. These exclusive rights allow CRL the ability explore within the historically productive Tamar Valley Mining District. 

The Tamar Valley License Area is adjacent to CRL’s Redmoor License area and extends northwards and eastwards from Kelly Bray to the Tamar River, and contains the historic Prince of Wales Mine, Gunnislake Clitters and Drakewalls Mines, along with numerous other sites of geological interest.

What does the granting of these Mineral Rights mean?

The granting of Mineral Rights permits exclusive access to CRL to explore for minerals within the Tamar Valley License Area, with the aim of identifying any potentially economic mineral occurrences that are located within the area.

This does not mean that CRL has unrestricted access to the land within the license. CRL will work closely with surface landowners and tenants to arrange land access and mitigate disruption. CRL has a strong track record of working with surface landowners and tenants to facilitate exploration activities, as evidenced by successful completion of drilling activities at Redmoor and through the completion of the Deep Digital Cornwall project.

The granting of the Tamar Valley License Area will allow for the identification of areas of interest, through the completion of desk studies and initial prospecting activities. Any areas of interest will then be subject to preliminary exploration, such as soil sampling, with the objective of confirming the presence of any minerals of interest.

What kind of activities can we expect?

Mineral exploration encompasses a variety of different techniques and methodologies depending on the type of mineral deposit being explored for, typically early-stage exploration is focused on reconnaissance and the collection of baseline data, this is typically done through the collection of stream sediment and soil samples, geological mapping, and the collection of rock samples and geophysics.

If a mineral or geochemical occurrence is identified, the exploration program can focus on smaller areas that require more comprehensive exploration techniques such as trenching, detailed geochemical sampling and geophysics. If there are positive indications that there may be economically significant mineral occurrences, then diamond drilling using a borehole drill rig may be employed to drill the subsurface to extract rock samples used to identify the extent and type of mineralisation. CRL have successfully completed 32 boreholes at Redmoor over two 6-month drilling campaigns.

This process typically happens over several years, with project development often taking up to 15 years and being subject to planning permission. To successfully identify a potentially economic mineral deposit, these exploration techniques are undertaken with the highest diligence to ensure that nothing is missed, whilst working to strict environmental standard, and limiting disturbance.

Importantly, these processes are not undertaken without close communication with all stakeholders and engagement with local landowners, tenants, and communities.

What impact will this have on the local community?

CRL always aims to have a positive impact on the local community. All our activities are carried out with the local community and environment at the forefront of our plans, and we aim to cause as little disruption as possible. The early stages of the exploration process are typically very-low in terms of visible activity, with little to no impact on people or environment, but we always aim to work transparently so that local communities and stakeholders are aware of our activities and can raise concerns and/or ask questions should they arise.

CRL has previously undertaken two drilling programs and maintained high environmental standards throughout, adopting novel environmental mitigations to reduce impact on the environment or communities. CRL also maintained strong environmental standards whilst undertaking its regional soil sampling program as part of the Deep Digital Cornwall program, engaging with well over 50 landowners, and at a minimum maintaining the integrity of the land which it worked on.

CRL aims to support local communities in improving the local environment and to involve them in our activities. CRL holds regular engagement events in Parish and Council halls to update its community on prpject activities and plans.

What’s next? 

In the near term, CRL will begin liaising with local councils, stakeholders and organisations in order to introduce ourselves and expand our regular community information events to all communities covered by our expanded operating area. Our events allow local communities and stakeholders to gain information about our activities, ask questions, and meet CRL staff members. 

CRL will continue desk-based studies focused on identifying areas of interest for initial exploration and reconnaissance. CRL aims to undertake preliminary geochemical soil and stream sediment sampling surveys during 2024 in identified target areas. Furthermore, any economically interesting mineral occurrences may be subject to more advanced exploration, such as diamond drilling. Drilling activities require permission from Cornwall Council and information on these activities will be published well in advance of their commencement.

Cornwall has a rich and extensive mining history and CRL believes that some of these historical areas, deserve further exploration and have great potential to reinvigorate the mining industry in Cornwall.

Will there be a mine and, if so, what will it be like? 

CRL is currently undertaking exploration activities, primarily focused on Redmoor in Kelly Bray. Other regional exploration activities are aimed initially at developing satellite resources to a future potential mine at Redmoor. 

Any future mine will be subject to design during project feasibility stages and will pass through consultation and planning applications before it is built. Any mine at Redmoor, or within CRL’s operating area is expected to be underground and deep enough to limit surface disturbance. Modern surface facilities will service the underground mine and process the mined ore, and the location of these facilities will also be subject to further study.

What areas are covered by CRL’s licenses
