Cornwall Resources Ltd has intersected the “full thickness of the sheeted vein system” (SVS) in the first set of drill holes at the Redmoor tungsten-tin-copper project in the east of the county.

The company also mobilised the planned second rig on 8 September for the remainder of the drilling campaign.
Cornwall said that geological logging of the initial three holes on pad one indicated “visible” wolframite which is a main tungsten-bearing mineral, and the copper-bearing mineral chalcopyrite.
The findings are also consistent with mineralisation already identified and modelled at Redmoor.
The project’s SVS hosts “higher grade mineralisation zones” that formed the basis of the 2019 mineral resource estimate.
The company now awaits assay results for the final interpretation.
The rig has moved to pad two, and on 9 September began drilling the fourth hole.
Pad three is scheduled to be set up on 11 September and drilling of the fifth hole, in the current programme, will follow soon afterwards.
Both drill rigs will be in place for around three months with up to three holes planned from each pad.
Managing director Dennis Rowland added that the addition of the second drill was expected to accelerate the campaign.
Cornwall also plans further testing and studies to understand the processing design, concentrate recoverability and grades.
The revised MRE is expected during the first quarter of 2026.
The current 2019 MRE is 11.7 million tons at 1.17% tin equivalent (0.56% tungsten trioxide, 0.16% tin and 0.50% copper).
The company said that the figures highlighted the “high tungsten content of the Redmoor deposit relative to many other global tungsten projects”.
