On September 30, 2023 the Czech team of the SEMACRET project from the Czech Geological Survey organized a field visit to the region of the Staré Ransko ultra-mafic complex which is one of pilot localities of the Project.

The plan is to use large archive of drill logs and new samples for 3D modelling of the Ransko massif that hosts several undeveloped Ni-Cu-(Co-PGE) deposits. The aim is to increase knowledge about the massif and mineral deposits genesis. The first stop was at the Nature Conservation Agency of the Czech Republic, Headquarters of the Protected Area “Žďárské vrchy Hills” in Žďár n. Sázavou where we introduced the EU Project and discussed with representatives of this Agency possible collaboration including field work by our project partners. After that we continued to the Staré Ransko mining district where we visited abandoned mining site of the Obrázek Cu-Pb-Zn deposit (Tereza schaft) and sampled several natural outcrops of coarse-grained gabbro which will be used for geochemical and geochronological study.

The excavation of the shaft started in 1962 and it reached the depth of 196.3 m It was closed in 1989.
