Summary:
The Vasilkovskoye deposit belongs to the group of intruded-related Au deposits. It is located in the western part of the Shatskaya metaliogenic zone of the North Kazakhstan province, with a northwest trend.
The deposit is located in the endo-exo contact of the Altybaysky granite intrusion (part of the Zerendinsky Complex) with the Precambrian metamorphic rocks. Within this contact occurs a large gold gas chemical halo, which represents a thermal aureole caused by the granitic intrusion, and where the gold enrichment took place.
The Altybaysky intrusion is crossed by a considerable number of faults, with main directions being NW and NE. These two main faults are the Vasilkovskoye fault (NE strike) and a major northwest trending structure parallel to the Dongulagashsky fault (NW strike). The deposit is situated in the northeast quadrant of this intersection.
The Altybaysky granite intrusion is represented by two major units at the Vasilkovskoye deposit; a diorite/gabbrodiorite unit and a granite/granodiorite unit. Planar and sharp contacts between the two units are common, although sometimes contacts are different.
The diorite/gabbrodiorite unit is located in the northern part of the deposit, and shows generally weak mineralisation. This unit represents the transitional zone between the metamorphic host rocks and the Altybaysky intrusion granite rocks. The Granite/Granodiorite Unit occupies the majority of the deposit and hosts the m ........
Summary:
The Vasilkovskoye mine is a conventional open pit mine. The ore and waste rock is drilled and blasted prior to excavation by diesel-hydraulic excavators. The ore is loaded into diesel powered off-highway rigid dump trucks and hauled to either one of three in-pit stockpiles, depending on grade, or dumped directly into an in-pit crusher.
Waste rock from the mining operations is transported to one of two rock dumps located on the east and west sides of the pit. Waste is transported to the closest dump to the face being excavated. Sufficient waste dump capacity is available for the whole mine life but waste haulage distances increase as the mine deepens and the waste dumps extend further from the pit rim. The current average haul distance is 1.5km from the face to the waste dump.
