Way to the richest Lomonosov deposit

The depth of the open pit is 100 m but in order to get out of it one has to overcome some kilometres along the narrow serpentine road. It demands a lot of fuel so malefactors often make attempts to get hold of the diesel fuel.
Excavators and trucks daily take thousands of tons of ore out from the pit. One million of tons has approximately 100 kg of diamonds.
