The unique properties of tantalum and niobium determine a stable and reliable demand now and in the future. Modern industry is significantly interested in using these elements.
In 2019, Taurus Infiniti LLC carried out a preliminary geological and economic assessment of the ore occurrence Mostove. As a result, reserves of category C2 and resources of category P1were approved in the State Service of Geology and Subsoil of Ukraine
TANTALUM ORE RESOURCES OF THE MOSTOVE DEPOSIT

As a result of the technical and economical report preparation, the sufficient attractiveness of the project according to standard indicators of investment projects is shown.
GENERALIZED TECHNICAL AND ECONOMIC INDICATORS
|#||Indicator’s name||Values (annual or total)|
|1||Balance reserves, thousand tons||350.791|
|2||Annual ore production, thousand tons||70|
|4||Capital investment, $ million||5.89|
|5||Concentrate price, $/t||89.43|
|6||Net cash flow, million $||3.61|
|8||РВР – payback period, years||5|
Prospects for increasing the resource base
There are two more mineralization zones at the Mostove project, whose reserves have been previously estimated. Vys’ and Kopanky mineral occurrences are located 2 km north-north-west and 1.5 km south-west. The prospective Ta2O5 and Nb2O5 resources of Р2 category were estimated.
They can be considered as an increase in the resource base.
INCREASE IN THE RESOURCE BASE
|Objects||Category||Ta2O5 resources, t||Nb2O5 resources, t|
|Mineralization zone 1 of Mostove project||P2||107,7||126,32|
|Mineralization zone 2 of Mostove project||P2||147,2||283,36|
|Vys’ mineral occurrence||P2||871,5||1098,3|
|Kopanky mineral occurrence||P2||576,0||661,1|
Proceeding from the above our resource base can be increased by:
− Ta2O5 from 992.1 t to 2,694.5 t;
− Nb2O5 from 514.7 t to 2,683.78 t.
