Start of Drilling at Redmoor Project
26 June 2025
Strategic Minerals plc
("Strategic Minerals" or the "Company")
Start of Drilling at Redmoor Critical Minerals Project
Strategic Minerals plc (AIM: SML; USOTC: SMCDF), an international mineral exploration and production company, is pleased to provide an update from its wholly owned subsidiary, Cornwall Resources Limited ("CRL"). The Company is pleased to announce the commencement of CRL's fully funded and permitted 9-borehole drill programme for c.5,300m of new diamond core drilling at the Redmoor Tungsten-Tin-Copper Project ("Redmoor").
CRL is exploring for resources of tungsten, tin, and copper in its Tamar Valley licence areas in east Cornwall, with a key focus on Redmoor.
The rig has commenced drilling the first of the three boreholes located at the current drilling pad, on Redmoor Road in Kelly Bray, Callington (Figure 1), with these three boreholes expected to take up to three months to complete. An additional rig will then join the programme for up to a further three months, to support the completion of the 9-borehole programme.
Data from drilling and the ongoing relogging and sampling programme will be utilised to inform a new JORC (2012) compliant Mineral Resource Estimate ("MRE") for Redmoor, expected to be completed in Q1 2026. This will be the first update since Redmoor's JORC (2012) compliant MRE published in 2019 of 11.7 Mt at 1.17% Tin equivalent (0.56% WO₃, 0.16% Sn, 0.50% Cu). Since that update, there have been significant shifts in global markets and commodity prices, with increased recognition of the importance of critical minerals. The Company believes that Redmoor's resource stands out in comparison to most tungsten projects due to the high-grade of tungsten mineralisation, alongside the presence of tin and copper.
This drill programme follows the securing of match grant funding from the UK Government, through the UK Shared Prosperity Fund, managed by the Cornwall and Isles of Scilly Good Growth Project (the "SPF Project"), and the completion of a £1,000,000 fundraise by Strategic Minerals. As the drill programme forms part of CRL's SPF Project, 50% of the programme costs will be recovered from the grant funding.
Dennis Rowland, CRL Project Manager, commented:
"This is an important moment for the Company, for Cornwall, and for the UK. The drilling now underway is the first exploration drilling at Redmoor since 2018 and aims to enable the accelerated development of a potentially important new domestic source of critical minerals. Tungsten is essential in various high-performance applications, from industrial tools to aerospace and defence. We are excited to highlight through this drill programme the potential of Redmoor as a strategically important, high-grade, polymetallic tungsten resource right here in the UK. We look forward to announcing results as the programme advances."
