Czechia – Core drilling – Strukturní ložiskové vrty NPVP – čistecko-jesenický masív a smrčinské krystalinikum

The subject of the public procurement is the implementation of four deep core structural boreholes using the wire-line method in the area of the Čistecko-Jesenický massif and Vernéřov u Aše, the acquisition and delivery of the core sample in preserved depth continuity at the required average yield of at least 95%, and the performance of related technical measurements. The maximum scope is 2 050 m. The fulfillment includes, in particular, continuous and final inclinometric measurements, caliper logging, spectral gamma logging K-U-Th, magnetic susceptibility logging, optical imaging of the borehole wall using the OTV method, technical documentation, borehole abandonment and transportation of the core sample to the material documentation warehouse of the Czech Geological Survey in Lužná u Rakovníka.
