Kalgutinskoye deposit - is the world-class tungsten-molybdenum-cooper deposit located in the the south-eastern part
of Altai mountains in Kosh-Agach district of Altay Republic near the state boundaries of Mongolia, China and
Kazakhstan.
Currently about 600 quartz veins (including 72 balance veins) and veinlets with the total tracked horizontal length of above 7000 m
were identified at the deposit. About 100 quartz veins were tracked along the strike; from among them max 15 of the main ones
were explored in depth by workings and drillholes. The biggest ore body at the deposit containing up to 40 % tungsten and
molybdenum balance reserves is blind vein №87 characterized by thickness up to 3.2 m, vertical and horizontal length above 400 m.
The main gangue minerals include quartz, muscovite, orthoclase, albite, fluorite, sericite and the main ore minerals include
tungstenite (1-40%), molybdenite (1%), chalcopyrite (1%), beryl (0,1%), sheelite, (0.1%), bismuthinite (0.1%) and subordinate
development of other sulphides (fahlore, chalcocite, covellite, bornite, arsenite, pyrrhotine, galenite and other) and products of their
hypergenesis (limonite, goethite, malachite, azurite). Distribution of tungstenite is extremely nonuniform; its grade in veins varies
from 0% to 30-60 %.
All the above ore minerals are contained as finer dissemination in host rocks as well, forming a wide halo of vein-disseminated
mineralization – greisen fringes up to 1-4 m thick.
Pegmatite type mineralization is represented by quartz, orthoclase, muscovite, molybdenite (0.8%), beryl (0.1%), chalcopyrite (0.1%),
covellite and chalcocite (0.2%), tungstenite (0.1%), pyrite.
Veinlet-disseminated copper-molybdenum (porphyry) ores contain quartz, feldspar, biotite, fluorite (2%), chalcopyrite (0.7%),
molybdenite (0.3%), and tunstenite (0.2%).
1937 – The Kalgutinskoye deposit was discovered by the geologist V.A. Zhurkin who tracked down talus quartz with
molybdenite and wolframite mineralization; samples were collected from a microgranitic storkwork body as well and
analyzed for molybdenum. Later it was named Molybdenovy Shtock (Molibdenum Stock).
1938-40 – Geological exploration and mining of the deposit. These were supervised by M.S. Baklakov. During these years
M.S. Baklakov prepared 10 geological and industrial reports that were substantiating a large scale of the Kalgutinskoye
deposit based on consistent discovery of 60 wolframite-quartz veins and consistent extension of tungsten ore reserves.
1941-1944 – The Oirotskaya exploration and operation crew of Zapsibtsvetgeologia carried out exploration and actual mining
of the Kalgutinskoye deposit under the supervision of the geologists M.G. Rusanov, P.M. Bolshakov, L.M Zaretsky. The
geological exploration carried out made it possible to make estimates of the Kalgutinskoye deposit reserves at: 2843.0 kt ore
reserves, 38.97 kt reserves of tungsten trioxide, 9.913 kt molybdenum reserves.
1948-1954 – In this period the Kalgutinskoye deposit was mined by a cooperative association of prospectors of the Aktashsky
ore mining department of Glavvolfram at the USSR Ministry of Non-Ferrous Metallurgy. During development of one of the
latest adits № 15 massive bonanza wolframite-quartz vein № 87 was discovered at the Kalgutinskoye deposit.
1982-83 – The Yuzhny Kalguty (South Kalguty) deposit was discovered. That was completed owing to geological survey by
V.A. Omelchenko who made a detailed pattern of ore mineralization at the Yuzhny Kalguty deposit.
1979-1992 – the Aktashsky ore mining department resumed geological exploration of the Kalgutinskoye deposit aimed at
prospecting of tungsten ores and start of developing adit №18– an underground working more than 2,500 m long that was to
become the main haulage level.
1992-1998 – B.G. Sementsov made “General Revised Estimation of the Kalgutinskoye Molybdenum-Tungsten Reserves as of
01 January 1997”, with reserves and resources estimated. The main result of the work done was ranking of the Kalgutinskoye
deposit as a large-scale porphyry-copper deposit with copper reserves of 585.0 kt, molybdenum reserves of 147.0 kt and
tungsten of 162.0 kt. B.G. Sementsov described “rare alkaline metals” mineralization with estimation of lithium, rubidium
and caesium resources.
2005-2008 – OOO “Kalgutinskoye” was mining high-grade ores of wolframite-quartz vein № 87, producing 19-21 kt
wolframite ore per summer.
2012-2013 – IMC Montan completed “Report on Mineral Resources of the Kalgutinskoye Tungsten-Molybdenum Deposit”
and confirmed the dominating stockwork porphyry copper-molybdenum mineralization as prospective for commercial
mining.

The Kalgutinskoye ores contain a wide spectrum of metals - copper, tungsten, molybdenum, beryllium, bismuth, lithium,
rubidium, caesium and a number of others. At the deposit there are high reserves of fluorite as well.
Reserve tonnage scale and other factors predetermine feasibility of setting up efficient operations for extraction of a whole
range of minerals.
The following elements – tungsten, molybdenum, bismuth and copper – are of industrial importance.
Chemical Composition of Ores
70-80 % of tungsten is represented by wolframite that can be observed as tabular and lamellar crystals from dust to crosssection of 25 mm. Infrequently the wolframite crystals are grouped in crystal clusters and intergrowths. Content of WO3 in
saleable ore is from 0.4 to 2.4%
70-80 % of molybdenum is represented by molybdenite that is observed as scales from hundredth fractions to 2-3 cm in
diameter. Molybdenite content varies from 0.19 to 0.55 %.
80-90 % of copper is represented by primary (chalcopyrite) and secondary (chalcosite, covellite, bornite) sulphides. The
average copper content of saleable ore is 0.36%.

The mineralization is polymetallic both geochemically and economically. Of commercial importance alongside with
“greisen” metals (Ве, W, Мо) are Сu and Вi. High content of elements in various geochemical groups - Nb, Та, Вa, U,
Li, Rb, Сs, La, Lu, Аu, Аg, Рt, Рd, Оs, Rh, Сd, Sb, Аs, Pb, Zn, Сr, Мn can be observed.
The ores are characterized by a significant list of ore and vein minerals (over 50). In addition to widespread oxides,
sulphides and sulphosalts native elements – Au, Bi, Cu – can be observed, which characterizes major and giant
fields.High concentrations of precious metals were found in geological formations of the Kalgutinskoye REM greisens
deposit. Gold can be observed in nuggets, high concentrations of the element are found in graphite grains (to 100 g/t)
and in pyrite (54 mg/t). Silver is mainly found in sulphides and sulphosalts (to 7.3 %) and is the major gold impurity.
High concentrations of PGMs are typical for pyrite, wolframite, molybdenite. It is expected that PGM mineral free
forms are present as well. Precious metals are characterized by nested distribution, which indicates prospects of byproduct extraction of precious metals.
The data of the Kalgutinskoye ore forming conditions available are consistent with parameters of forming productive
stages of tungsten-molybdenum ore formation at major deposits of the world, which once again underlines high
prospects of the deposit’s ore field.
Cosmic structures of the Kalgutinskoye REM deposit (the Altai Mountains) were studied using materials of
multispectral satellite survey Landsat; ЕТМ+ and satellite radar mapping SRTM. – The Kaltuginsky granite massif and
the deposit proper are in the inner belt of the structure in a ring 15.2 km in diameter. Ore-bearing prospects of the southeastern part of the district were highly assessed.

Porphyry Copper Ores
Porphyry copper mineralization was explored only on some sites of the mine claim. C1+C2 ore reserves
are 350.0 Mt, P1 resourcesare 2.1 bn t at the average content of 0.06% WO3, 0.04% Mo and 0.17 %Cu.
Given tungsten/copper and molybdenum/copper conversion ratios of 6/1 and of 5/1 respectively, the
average content of copper equivalent in porphyry copper ores will be 0.73%.
Since at present ores involved into surface mining are at the average content of 0.38% Cu (the
Tominskoye porphyry copper deposit, Chelyabinsk Oblast, Russia) and 0.47% Cu (Oyu-Tolgoi, the
largest copper deposit in the world, Mongolia), the Kalgutinskoye ores at the average content of 0.73
(copper equivalent) have good prospects of surface mining at annual production of 10.0 and more million
tonnes.
Presence of mineralization areas at higher Cu and Mo content enables planning porphyry copper ores at
the average content of 1.0-1.5 % for surface mining within first 10-15 years. For example, Las Bambas
operating project, Peru, with resources of 500.0 Mt at the average content of 1.14% Cu has similar ore
parameters.
By-product extraction of such economic components as bismuth, beryllium, lithium, rubidium, caesium,
osmium, niobium, tantalum that are contained in the Kalgutinskoye ores, and infrequently in commercial
content, considerably improves technical and economic indicators of porphyry copper ore surface mining.
Quartz-Vein and Pegmatitic Ores
Quartz-vein ores are distinct for higher content of economic components and hence higher commodity value. These ores have been explored
well; and presence of all the required infrastructure and underground workings ensures prompt organization of annual production of 360.0 kt
– 1.0 Mtpa. The Kalgutinskoye high-grade ore reserves and resources of 18.2 Mt enable highly profitable mining of the ore for 20-30 years.
