Strategic Minerals plc’s subsidiary, Cornwall Resources Ltd, has discovered a new tin zone of “meaningful scale” at the Redmoor tungsten-tun-copper project in southeast Cornwall.
SCALE
Named the ‘North Tin Zone’, the “distinct and continuous, tin-dominant zone of mineralisation” lies outside of the project’s sheeted vein system deposit and was previously unnoticed.
The discovery is based on analysis of results from drill hole CRD041, historical relogging, newly validated 1980s datasets, which resulted in a new deposit model.
Strategic said that revised geological modelling of the North Tin Zone, indicated a “laterally continuous mineralised structure”, which might potentially support a future mineral resource definition.
The company defines ‘meaningful scale’ as a “structure that is continuous over multiple, well-spaced, drilling intersections and with a potential volume and intersection grades sufficient to justify estimation”.
Sample results from CRD401, which intersected the North Tin Zone containing visible cassiterite (tin oxide), included 4m at 0.25% tin and 0.01% copper from 476m.
Cornwall Resources is carrying out further targeted relogging and sampling of drillcore, outside of the sheeted vein system, to determine the extent of the new zone as well as other non-sheeted vein system mineralised zones.
“Recent successes at Redmoor, including this discovery, reflect the project’s strengths and the team’s consistent strong delivery, supported by effective leadership, ” added Cornwall Resources managing director Dennis Rowland.
“The company considers the North Tin Zone of mineralisation to represent additional long-term potential for significant resource growth at Redmoor, alongside the aim for continued expansion of the SVS deposit, subject to drilling and estimation.”
