SRK was commissioned to produce a Mineral Resource Estimate (“MRE”) for the Tokum gold deposit in accordance with the JORC Code (2012).
The Boke epithermal belt is located in the accretionary belt of the Central Asian Orogenic Belt that is bound by the Devonian Rudny Altai arc to the northeast and the Urals-Zharma arc to the southwest. The Tokum gold mineralisation is characterised by the presence of low to moderate amounts of accompanying sulphide mineralisation. The deposit is located in the hangingwall of the regional Bokonsky thrust fault among carbon-bearing, essentially siltstone, deposits of the lower strata of the Bokonsky Formation.
The geometry of the Tokum deposit is very similar to that of the neighbouring Vasilyevskoe deposit. Tokum is orientated in a WNW-ESE direction, has a strike length of approximately 650 m and dips at approximately 55⁰ to the SSW. The maximum down dip extent of the modelled grade shells is approximately 600 m with the typical down dip extent being approximately 300 m. Thickness ranges from 2-3 m in the West zone to more than 20 m in the main, East zone.
No mining has been carried out to date at Tokum. Exploration commenced in 1976 and has continued in numerous phases to the present.
As was the case for the MRE of the Vasilyevskoe deposit, SRK provided technical assistance to the Client in the form of core logging and sampling training. In addition, SRK assisted in the development of detailed procedures for geological and geotechnical logging, sampling, QAQC and laboratory protocol.
