Dobrinja & Pranjani Lithium-Borate Projects
Serbia (100%)
The Dobrinja and Pranjani licence areas are located in western Serbia approximately 90 km south-southwest of Belgrade.
The Project area is covered by two exploration licences covering approximately 64 km2 (Dobrinja 38 km2, Pranjani 26 km2) of outcropping Neogene age basins containing lithified lacustrine sediments mapped as early, middle and upper Miocene.
Earlier studies carried out by the Yugoslavian Geological Survey identified favourable lacustrine strata for hosting lithium and boron within the licenced areas, which was followed up by Jadar´s desktop studies that identified the basin’s potential.
Geology
The Dobrinja Basin is elongated in a northeast-southwest direction and filled by Neogene lacustrine sediments. The target lower Miocene sediments are exposed within western and eastern basin margins close to the contact with Basement formations. The lower Miocene sediments are overlayed by younger middle and upper Miocene sediments. The margins of the basin are either peridotites – serpentinite and diabase formation to the north, east and southeast and cretaceous limestone, paleozoic schist and triassic limestone to the west, southwest and south. The targeted lacustrine sediments sequence the lacustrine strata characterised by marlstone, claystone, ash-flow tuffs and spring aprons travertines.
The Pranjani Basin lies immediately northeast of the Dobrinja Basin and extends over an area of approximately 40 km2. Fine-grained lacustrine sediments of the lower Miocene age filled lake structural basin was subsequently overlain by middle Miocene. Dominated sediments are characterised by marls, claystones, siltstones, ash-flow tuffs and clastics flows close to the basin margins.
