The Taborny deposit is a structurally controlled zone of potassic metasomatism, hosted by Proterozoic sandstones. The mineralised zone dips moderately to the south and southsoutheast. Parallel to Taborny, and approximately 500 m south, is the smaller Temny deposit. Between Taborny and Temny are mineralised linking structures, and both deposits are covered by the same block model and one pit design, therefore “Taborny-Temny” is often referred to as a single entity.
Mineralisation at Taborny-Temny is associated with iron and manganese oxides, that follow from primary sulphides, particularly pyrite.
Approximately 1.5 km southwest of Taborny, and hosted by the same Proterozoic sandstone succession, is the Vysoky deposit. The Vrezanny deposit, 4 km west-northwest of Taborny, is also included as a satellite of Taborny, although the geological setting is different from Taborny, being hosted by granite-gneisses of the Archaean basement.
The Taborny, Temny and Vysoky deposits are situated in the western part of the Aldan shield, in the southwestern corner of the Uguskiy Graben. The graben is filled with Lower Proterozoic sediments of the Olonnokonskiy Formation, which discordantly overlie early Archaean gneisses and a later Archaean intrusive complex.
The major regional structural features are: 1) the N-S striking Tokkinsky Fault Zone (along the western margin of the Uguskiy Graben); and 2) WSW-ENE striking faults of the Kondinsky Fault Syst ........
