Historic mining districts across Europe are gaining renewed investment attention as existing infrastructure, skilled labour and geological knowledge become increasingly important factors in mine development. In northern Sweden, Viscaria is continuing preparations to reopen its copper mine in Kiruna. The company’s second-quarter update reported a total transaction value of approximately SEK 2.4 billion from directed financing and the conversion of SEK 681 million in shareholder loans into equity. In August, Viscaria also signed a long-term agreement with Sandvik covering underground mining equipment, drilling tools, automation, digital solutions and service support.
Viscaria Advances Kiruna Mine Restart
The project is being developed within one of Europe’s established mining districts, with access to skills, power, transport and existing industrial infrastructure.
The existing mining environment provides infrastructure and operational capabilities that would otherwise need to be developed as part of a new greenfield project, potentially reducing the distance between financing and production. Viscaria nevertheless remains dependent on successful mine restart and production ramp-up as it advances toward renewed operations.
Salau Exploration Revisits Historic Tungsten Workings
In France, Apollo Minerals is reassessing the historic Salau tungsten-gold mine, which operated from 1971 to 1986. The mine historically produced ore averaging approximately 1.5% WO3. An August review identified additional tungsten mineralisation, including the newly defined Veronique-Upper Zone.
Historical drilling in the zone included intercepts of up to 4.3 metres at 1.3% WO3, extending the target area around the former mine. Apollo still needs to establish whether historical mineralisation can support a modern economic resource and progress through permitting for renewed development.
Existing Infrastructure Shapes Project Economics
Historic mining districts provide assets that new exploration areas cannot quickly replicate, including roads, power systems, historical workings, geological information and established mining labour markets. Processing facilities, rail connections and previous permitting activity can also provide advantages for brownfield developments.
These factors have become more significant as higher construction costs increase the expense of developing new infrastructure. New roads, transmission infrastructure and underground development are more costly than at the beginning of the decade, while permitting new infrastructure can take nearly as long as permitting a mine. Brownfield projects still carry legacy environmental liabilities and complex historical geology, but they can require less new infrastructure and potentially reach operational milestones faster. The resulting project landscape increasingly includes historic mining regions from Cornwall to Kiruna, where the infrastructure surrounding former and existing mines forms part of the development value alongside the mineralisation itself.
