In this sense, it is crucial and a part of the social corporate responsibility (CSR) to start communication and stakeholder engagement already at the very beginning of mineral exploration. Here we present a methodology of stakeholder engagement that has been used by the Geological Survey of Finland (GTK) in mineral potential mapping in Southern Finland.
The stakeholder groups of local communities that are taken into account by the GTK’s stakeholder engagement in Southern Finland are local landowners, residents, media, schools and the municipality representatives. Direct contacts in the field, press releases, and conferences, as well as open and public meetings and lectures are the approaches to engage with these groups. Before the start of the activities, leaflets informing about the upcoming field work and associated contact information are delivered to local mailboxes. The stakeholder engagement is performed by geologists working at the region. It has been practiced and developed since the early 2000s. So far the stakeholder engagement has not been a systematic or standardized activity, but largely a polite and respectful approach towards the local communities. However, since the new mining act requires informing the landowners, and because public resistance towards mining activities is growing in Finland, such approaches and methodologies should be surveyed, developed, systematized and standardized while updating the GTK’s mineral potential mapping strategy. This should be made by reflecting the local conditions and stakeholder groups in different regions.
Several ongoing social science projects that study, develop, and promote CSR of mining offer possibilities for cross-disciplinary cooperation between geologists and sociologists. Cooperation could involve studying the impact of GTK’s stakeholder engagement in order to receive feedback for developing and improving the social performance of field activities. Nevertheless, the GTK’s stakeholder engagement has until now been a very productive and effective activity in Southern Finland, resulting in SLO.

The zircon U-Pb geochronology defines an age of 1891 ± 5 Ma for the UGB, which is slightly older than most mafic intrusions in south-western Finland. The obtained chondritic initial zircon ɛHf values with E-MORB type geochemical affinity suggest a sub continental lithospheric mantle source for the UGB. The overall geochemistry indicates that the UGB magma as well as other E-MORB type rocks in the Pirkanmaa and Hame belts were formed in a rift-related environment in a fore-arc region at 1.89 Ga, predated by arc-type magmatism at ~1.90 Ga and back-arc magmatism at ~1.92 Ga in the Tampere belt. Slab retreat due to roll-back is suggested to cause the extension and related magmatism in the fore-arc region. Moreover, the timing and compositional and isotopic changes of early-orogenic magmatism are broadly compatible with intervals of extension and contraction, i.e., a tectonic switching model, and may provide a perspective to rapid build-up of Paleoproterozoic crust. Structural characterisation provides a framework where gold mineralisations are preferentially located within the high-strain north-eastern domain of the UGB, within fracture networks adjoining the high-strain zones. Our results indicate that neither the geochemical composition nor age of the intermediate-mafic intrusive host rocks play a major role in controlling the formation of gold mineralisation. By contrast, the localization of orogenic gold is controlled by localised structures (shear zones, fractures), and the variation in lithological composition of the intrusive host may contribute to the style of the mineralisation.

However, no copper has been produced from this deposit type in Finland, and only one deposit and a few prospects of this type are known. We describe here the results of an assessment of copper, molybdenum, silver and gold resources in porphyry-type Cu±Mo±Au deposits in Finland. The assessment is part of an ongoing series of assessments started by Geological Survey of Finland (GTK) in 2008 to estimate the undiscovered resources of several metals in the Finnish bedrock.

The Cu-Mo mineralisation and its host rock have several features which are comparable to porphyry copper systems, and observations also support epithermal gold potential for the volcanic units next to the intrusion. However, Au mineralisation appears to be connected to overprinting shear structures in the intrusion.
