Alexander Boytsov, ARMZ Uranium Holding Co., 2009, presented the following:
- Recoverable uranium resources in Elkon amount to 5.3% of world uranium resources, which makes it second biggest U deposit
- In situ known U resources 344 ths.t at 0,158% (recoverable 289 ths.t)
- Elkon uranium mining company was established by ARMZ in November 2007.
- About 20 ore bodies located in 3 ore zones within the Yuzhnaya fault zone:
Ore bodies have complex morphological structure with significant variations in thickness over short intervals as orebodies bulge and narrow.
Ore zone includes areas with closely-adjacent and parallel veins, making selective mining difficult. Bulk mining will add more dilution requiring radiometric sorting.
Length of ore bodies along strike: 50 to 400m, up to 700m;
Length of ore bodies down dip: 100 to 200m.
Thickness varies from 0.9 to 4m, average about 1.3m
Elkon is realizes in the framework of state-private partnership «Complex development of South Yakutia» to allocate state financing for development of the Elkon infrastructure.
The following infrastructure construction will be financed by government:
Railroad connecting Elkon deposit with Tommot (53km)
Road connecting the deposit with Tommot (10 km)
High voltage electric line connecting Elkon with Aldan including substations
At the Elkon deposit uranium mineralization occurs largely as brannerite (U4+,Ca)(Ti,Fe3+)2O6 The mineral is a refractory ore of uranium. In addition other uranium minerals are present in lower amounts such as: coffinite (U,Th)[(OH) 4x|(SiO4)1-x] and uraninite UO2 The uranium minerals occur in breccia fragments in the calcite-fluorite veins. Gold occurs as sub-micron grains or micron sized inclusions in pyrite and galena. The sulphides occur in quartz and calcite as inclusions and in fractures and on grain surfaces.
Basic principals for Elkon feasibility study:
Technical expertise of international engineering companies
Resources classification according to JORC
3D modeling
DCF modeling
Setting up favorable conditions to attract investments
