What We Do
CTL has discovered high-grade tin deposits of global significance and also a hard-rock lithium field in the rare G5 granite with the potential to be among the largest in Europe. The potential tonnages and grades put the Company firmly on a path towards mining and production.
CTL is at the intersection of surging global demand for tin and lithium, forecast supply deficits from 2028, and the increasing geopolitical necessity of securing domestic supplies of critical minerals. CTL is run as a growth engine: our ongoing success in discovering world-class tin and lithium deposits within our mineral rights areas, directly drives strategic additions of mineral rights. CTL now has mineral rights control over 14% of Cornwall.
Location: West Cornwall | Focus: High-grade tin systems
CTL’s first flagship tin project, (Great Wheal Vor) covers 26 former producing mines known in their day as the “richest tin mines in the world”. These include Wheal Vor and Wheal Metal. CTL drilling to date has identified 28 high-grade tin targets.
Eight new tin lodes discovered, including:
South Vor Footwall: peak grade 6.28% Sn · Hichens Lode: peak grade 5.63% Sn
Goldilocks Cluster: one of our 28 targets at Vor, identified by nine tin intercepts within a >155m wide interval
A new high-grade tin system located below the old Wheal Vor workings (historically among the richest in the world), the Goldilocks target zone has the potential to be approximately three times the size of the Vor historic workings. The Vor Main Lode alone produced ~45,000 tonnes of tin metal.
Location: Tregonning Granite, West Cornwall | Focus: Hard-rock lithium in rare G5 granite, with major new tin discovery
The new lithium field we have discovered in our combined Tregonning North and Tregonning South project areas (combined total 1,129 acres) has the potential to be one of the largest mica-granite lithium fields in Europe.
Mineral rights control of Tregonning South was acquired by CTL in February 2025. Exploration drilling on Tregonning South completed in 2026 has confirmed continuity of the new lithium field over approx 3.27 km. This includes multiple lithium-enriched sheets at various depths with true widths of up to 6.8 metres. Additionally, we have discovered a major new tin system at Tregonning South: to date, drilling has so far intercepted 10 tin lodes and a sheeted vein system.
The JORC Lithium Exploration Target (Feb 2025) on Tregonning North alone reported an average 197.5 Mt (ie 67 – 328 Mt) grading 0.26–0.32% Li₂O, but this does not include the upside of Tregonning South, which is more than double the area of Tregonning North.
One of the most significant hard-rock lithium opportunities in Europe, now with the additional discovery of a major tin system.
Location: East of Bodmin | Focus: High-grade tin systems
Group of 24 former producing tin and copper mines
Historically ranked 3rd in Cornwall for total output
Historic grades up to ~6.5% Sn prior to closure in 1914 due to outbreak of WW1
We have carried out extensive digitisation of all available mine plans and identified multiple high-grade tin targets.
Strong exploration potential within a proven high-grade tin district. The Phoenix group of mines are a valuable pipeline project for CTL, with mineral rights grants secured by CTL from both the Duchy of Cornwall and the Crown Estate.

Source: CTL internal estimates and publicly disclosed company filings. Tregonning North is a JORC Exploration Target reported in 2025, shown at the midpoint of the disclosed 67–328 Mt range; Tregonning South and combined total are estimated potential, shown with dashed outlines to distinguish from JORC-compliant figures. No equivalency is implied between Exploration Targets, estimates and Mineral Resources. The potential quantity and grade of an Exploration Target is conceptual in nature; there has been insufficient exploration to estimate a Mineral Resource and it is uncertain whether further exploration will result in the estimation of a Mineral Resource.
28 potential high grade tin targets to date at Vor
Discoveries of eight new tin lodes at Vor including:
Tin is classified as both a Critical and a Growth mineral in the UK Government’s Critical Minerals Strategy — essential and irreplaceable in the growth sectors leading the clean energy transition.
Applications
Lithium is among the most strategically critical of all minerals. Like tin, it is now classified by the UK Government as both a Critical and a Growth mineral, and is fundamental to electrification, energy storage and mobility — underpinning the UK’s electric vehicle, battery storage and clean energy ambition.
Applications
Cornwall’s mining history stretches back more than 4,000 years. Tin production had a defining role in Bronze Age Britain, and throughout later industrialisation. That heritage is not merely historical. The same geology that powered Britain's Industrial Revolution contains the minerals that will power its clean energy transition. CTL exists to unlock that potential. Its dual commodities of tin and lithium are at the very top of the supply chain which is essential to power UK economic growth and reinforce our national security. Modern geological techniques, applied by CTL to this historically rich district, have already yielded globally significant discoveries. The UK Government has designated tin and lithium as Critical and Growth Minerals, with fast-track planning support and a strong policy framework for domestic critical mineral development.
