The geological conditions at the Čukaru Peki copper mine near Bor in Eastern Serbia, are not exactly ideal for exploration drilling. The ground consists of complex formations, mostly andesite and quartz, mixed with various types of clay and sand, intersected throughout by fractures and faults.
Furthermore, the material is hard – between 7 and 9 on the Mohs scale – and notoriously porous, especially in holes more than 2000 m deep. All this makes exploration drilling a daunting task, but not for Geomag DOO.
This company, which is one of the region’s top core drilling contractors, is proving that extreme conditions can be overcome with the right equipment and technology.
Based in Belgrade, Geomag has some 80 employees, a fleet of 10 drill rigs and operations throughout the country. It also numbers some of the world’s biggest mining companies among its clients such as Rio Tinto and ZiJin.
