Silver of Tajikistan

Konimansuri Kalon

The International Finance Corporation (IFC), a member of the World Bank Group, has been retained by the Government of Tajikistan as the Lead Adviser in the implementation of a transparent selection of a private mining developer to undertake the exploration and subsequent development of the Konimansuri Kalon (previously known as Bolshoy Konimansur) silver deposit. The Konimansuri Kalon silver, lead and zinc deposit is located in the Sughd administrative division and province of Tajikistan, 51 km northeast of the provincial capital of Khujand. The area is seismically active (Modified Mercali Scale 8). Polymetallic, silver-lead-zinc mineralization is the most economically significant in the area, with minor copper-bismuth mineralization occurring at depth.

silver-shutterstock-333The Konimansuri Kalon deposit represents a uniform stockwork with a 2.4 km strike length, oriented in the northwest direction, with a width of 600 m to 800 m and an average thickness of 500 m. Exploration data for the Konimansuri Kalon deposit was made available to Micon International (IFC’s technical advisor) to create an electronic database and digital model for the deposit. The result of Micon’s work is a database containing sample assay data from exploration drill holes and underground workings, and 3 D wireframes of the topography, the geological contacts, the GKZ approved mineral reserve blocks and the open pit designed to exploit the GKZ approved mineral reserves.

The digital database was used as the basis for Micon’s estimate of the mineral resources of the Konimansuri Kalon deposit, following the definitions and guidelines of the Australasian JORC Code and CIM Standards on Mineral Resource and Reserves. Konimansuri Kalon Mineral Resources at 30th September 2009 are estimated as follows:

Category Cut-Off Grade Ag (g/t) Tonnage (Mt) Grade Contained Metal
Ag (g/t) Pb (%) Zn (%) Ag (kt) Pb (kt) Zn (kt)
Indicated 15 700.0 69 0.35 0.30 48 2,474 2,117
Inferred 15 355.2 61 0.25 0.22 22 888 778
Total 15 1055.2 66 0.32 0.27 70 2262 2895

Power lines and other supply infrastructure will be required to meet the expected 120 MW to 140 MW demand of up to a 25 Mt/y operation on Konimansuri Kalon. Given existing and projected national winter power deficits, power is a significant issue. . With appropriate permitting, the significant water supplies needed could be sourced from the Kayrakum reservoir albeit over a significant distance and elevation. Upgrading of the existing road between Adrasman and Khujand is not considered to be problematic.
