The geology at Rodnikova is similar in nature to that at Asacha. The deposit consists of a number of north-south trending veins hosted by a brittle dolerite intrusion, which is emplaced into a suite of volcanic rocks. Other volcanic rocks in the surrounding area have been interpreted to post-date the diorite but pre-date the veins. As at Asacha, it is postulated that the deposit is contained within a collapsed or eroded volcanic edifice.
The veins occupy a north-south structural trend and occur as a number of parallel veins the principal of which are steeply dipping, while further to the west the veins display moderate dips to the east.
