Within the scope of its business operations conducted in the communes of Bolesławiec and Warta Bolesławicka, PeBeKa bored exploratory boreholes with the depth of 1500 m in order to examine the deposition conditions of copper ore, its quality, lithostratigraphic profile, overburden, as well as hydrogeological, geological, engineering, and gas conditions.

Project outline
The boreholes allow the collection of detailed data concerning the geological conditions and ranges of the deposits of copper ore and accompanying minerals, as well as information on the mineralisation of copper and other metals occurring in the ore together with copper. The first borehole in the Grodzieńska Basin reached the depth of 1447 m, the second one – 1417 m, and the third one – 1278 m. After the completion of comprehensive hydrogeological tests the first two boreholes were equipped with piezometers for the observation and examination of underground waters.
The holes bored within the scope of the project enriched the knowledge of PeBeKa's specialists in the technology of core-logging of Permian sedimentary rocks, thus broadening the range of specialist services offered by the company.
Greatest challenges
Boring exploratory holes in winter
Key moment
Transporting and assembling the boring equipment consisting of an MR6000 self-propelled boring rig, mud tanks and pumps, and power generators.
