Local Geology
According to the regional geological mapping, the project area is mainly composed of crystalline metamorphosed shales of lower the Serbian-Macedonia complex and Tertiary (Eocene) formations. Quaternary alluvials have been deposited along the watercourses.
Serbian-Macedonia complex
The crystalline schists of the Serbian-Macedonian complex, subdivided into two phases, were originally geosyncline sediments consisting of fine-grained clastics with basic sub-marine volcanics interstratified. The Lower Phase is metamorphosed to epidote - amphibolite or amphibolite facies with local staurolite, while the Upper Phase, whose sediments were likely to have been deposited after the first phase of metamorphism, have been regionally metamorphosed to green schist facies with local epidote - amphibolite facies under medium pressure during the Baikal orogeny.
Tertiary
Tertiary formations, covering most of project area, include Eocene sediments and volcanics,
Oligocene marine sediments and volcanics and Neogene tectonic trench deposits.
Exploration Target
Since the project area is almost entirely covered by Tertiary sediments, the main exploration target is a Jadar analogue where the hydrothermal mineralisation is sourced from proximal granites, greisens and pegmatites that occur to the immediate west of the tenement.
To date there has been no modern systematic exploration for the target minerals at Vranje so the first stage will involve detailed mapping and geochemical of the surface geology to be followed up with scout drilling through the sediments to determine if there are any mineralised horizons in the sedimentary sequence.
Exploration and Mining History
The geology of the Vranje district has been studied by various government and academic
geologists since at least the 1930s including detailed studies of the granitoids in the region.
Mineralised, especially lithium and tin, bearing pegmatites and greisens were also recognised in the granitoids.
