In 2018, the research of metallic minerals that accompanied the preparatory construction works in the area of the construction of Corridor 11, and especially the Munjino Brdo and Laz tunnels, showed that there are substantial gold sites and a high silver content in those locations.
In the Munjino Brdo location, gold content of 5.74 ppm and silver content of 0.7 ppm was found in the phyllites core, as shown by the data from the Rulebook on Determining the Annual Program of Basic Geological Research for 2021, adopted by the minister of mining and energy of Serbia in late March.
The ppm tag (parts per million) pertains to a millionth part of a whole. In mining, gold ore of 0.5 ppm and up is considered profitable. Those under 5 ppm are considered lower class gold ores.
– In 2019, research was done on a part of Corridor 11 (Preljina-Pozega), Prilipac location, and research of dacite pyroclastic rock in the Ivanovci location near Ljig, and high content of rare metals such as beryllium, niobium, wolfram, silver and thorium – the rulebook says.
The document further states that, in 2020, the majority of the research activities were concentrated in the area between Preljina and Pozega on Corridor 11, where the Laz and Munjino Brdo tunnels were being built. High concentrations of chrome and silver were detected at the entrance to the Munjino Brdo tunnel at the time, whereas the exit from the tunnel features high concentrations of chrome, manganese, silver and cobalt.
Research along new corridors in Serbia has been done before, considering, as said, the construction of the road network on a relatively large scope in the past years, to the end of, with a minimum of financial investments, collecting substantial geological data from the locations “detected” in the process of road construction works.
In 2016, the biggest geological research activities were carried out on corridors 10 and 11. In the Takovo-Preljina area, along the route, “interesting mineralization of antimony, chrome, nickel and mercury” was discovered.
Geological research in the Takovo-Preljina area continued in 2017, as well as in the area of the construction of the route of Corridor 10, from Nis to Pirot, when two metallogenic zones were crossed: Ridanj-Krepoljin and Bor zones, where, as said, “very interesting mineralization of copper and gold” was discovered.
According to the document, the plan is to continue geological research along the corridors in 2021. This pertains to Corridor 11, Preljina-Pozega section, but also the Ruma-Sabac-Loznica route and all the other routes which pass through geologically interesting areas.
Golija and Ozren resting on gold?
It’s also interesting that the state has also been looking for noble metals on Golija and Ozren since 2018. The results of this research, according to the same document, have shown that these are very promising terrains when it comes to gold.
That year, a considerable increase in gold was registered on Golija, and in 2019, in a wider area of Ozren and Golija of around 200 km2, high gold content was registered again, which had not been registered in the previous research.
Research activities on these mountains continued in 2020, and the continuation of the research is planned for 2021 as well, both in these areas and further toward the northwest (Zlatar-Priboj area).
The research is planned to be completed in 2024.
