Karelian Diamond Resources plc has identified a “significant” and “promising” new copper target on the site of the historic Cappagh copper mine in County Tyrone, Northern Ireland.

The company has completed initial desktop studies and reconnaissance work since receiving the six-year licence KDR4 in May from the Department for the Economy.
Managing director Maureen Jones said: “The identification of the historic Cappagh copper mine within the recently granted KDR4 licence area is a very exciting development for the company and complements our existing understanding of the region’s broader mineral prospectivity, providing a tangible copper target.
“We look forward to commencing a comprehensive exploration programme to unlock the full potential of this area.”
Planned exploration will include detailed geological mapping and geochemical sampling with results adding to the current database which was analysed by Dr Larry Hulbert during 2024.
The company noted that Dr Hulbert identified nickel, copper and platinum group elements within the licence areas in Northern Ireland as well as other potential areas for review.
He also established a comprehensive database of geology, geochemistry, geophysics, remote sensing, and base Geographic Information System (GIS) information including TELLUS data and gravity geophysical data.
“This discovery further enhances the company’s strategic position in Northern Ireland, complementing the already identified significant potential for nickel-copper-platinum group elements (PGE) across its broader licence holdings in the region,” said Karelian.
“The KDR4 licence area covers an area with documented historical mining activity and geological indicators favourable for copper mineralisation.”
The company’s other focus is on diamond exploration in Finland.
