The Sable tin project is a near term development deposit, requiring a confirmation
Discovered in 1964, the deposit underwent intense exploration between 1972 and
1987 consisting of 230 800 meters of drilling in 539 holes, extensive mapping,
hydrogeology and metallurgy.
In 1987 the State Commission for Reserves registered 10 461 000 tonnes of ore (C 1
and C 2 / Measured and Indicated) at 0.88% Sn and 0.53% Cu. In 1993 a technical-
economic (feasibility) study was finalised, but due to both political and economic
conditions in Russia and dynamics within the Tin markets, the project did not
In 2012 Sable Tin Resources (Zaibaikalsk Mining Company) acquired a 20 year 7.3
km 2 exploration and mining license at a State auction.
The Sable deposit is located near the industrialised city of Komsomolsk on Amur, the
second city of the Khabarovsk Region in the Russian Far East.
The nearest population centre is the town of Solnechy which developed as the centre
of the large mining operations carried out in the district since 1960. The town hosted
the Solnechny Tin Mill, a major contributor to the Soviet tin industry.
Accessible by a 35 km unpaved road, the license is 15 kms directly North of the town
of Gorniy which hosts a tin processing plant pertaining to Rusolovo and 10 kms from
the Peryevalny Tin Mine which is currently under maintenance
The License lies 20 kms west of the Baikal-Amur Railway line and approximately 25
kms from a high pressure gas compressor station. Sufficient electrical supply is
available from an exisiting transformer station near the Peryevalny mine, 10km south
of the license area.
The Sable tin project is one of 9 economic deposits identified within the Komsomolsk
Ore District covering an area of 1000 km 2 in which 500 mineralised zones and 35
occurrences have been identified.
The Ore district lies on the Eastern part of the Khingan-Okhotsky volcanic belt and at
the intersection of the major Sikhote Alin – Mongol-Okhotsk tectonic systems within
the western part of the Sikhote Alin geanticlinal and silicate system.
The district is marked by complex Jurassic-Lower Cretaceous flysch sedimentations,
late cretaceous marine sedimentations and volcanogenic units. The youngest units of
the area cover sequences of Neogene basalts and complexes of unconsolidated
deposits of Quaternary age.
Regional faulting has limited the ore-bearing areas and has localized intrusions and
volcanic rock covers. Mineralisation is formed within a major 20 km shear zone and
associated NE faults with tin being the core mineral. All deposits are related to a
tourmaline type of cassiterite-silicate- sulphide unit reflecting the stages of the
1 – quartz-tourmaline (early) 2 – quartz-cassiterite 3 – quartz-sulphide 4 – quartz-
carbonate-sulphide 5 – calcite-pyrite (late)
Mineralisation in the Komsomolsk district is characterised by both horizontal and vertical zones:
A. Occurrences in the Jurassic sedimentary and partially in granites -Sn
mineralization (Solnechny and Pridorozhnoe deposits)
B. Ore near the surface of the unconformity of Jurassic sediments and Lower
Cretaceous sedimentary-volcanic formations – Sn and Cu-Sn (Festivalnoe)
C. Occurrences in Upper Cretaceous volcanics extending down to lower parts of the
Jurassic sedimentary strata – Sn, and poly-metallics in upper parts (Perevalnoe).
The Sable deposit is located in the northern diorite exocontact of the Hurmulinsk
volcanic-plutonic structure in a metamorphic transition zone from rocks characterized
by biotite to chlorite grade.
The basis of the geological structure of the area is complex Jurassic Lower
Cretaceous flysch formation and a late sedimentary-volcanic complex. These rocks
are intruded by Late Cretaceous acidic and intermediate intrusions including quartz
Tectonic structures are widely developed on a N-S axis with subsidiary, NW, and
WNW faults. Practically all are mineralized, with economic mineralization controlled
by NW and N-S structures.
Six large and medium scale and numerous small ore bodies were identified during
exploration. Explored resources are confined to three zones: Leningradskaya,
Sobolinaya and Nezhdannaya zones. These are cassiterite-silicate ore units of
cassiterite-tourmaline mineral type, similar to other deposits in the district.
Morphologically they are quartz-tourmaline impregnated vein bodies dipping 60-48°
except for the Leningradskaya zone and a part of the Nezhdannaya zone, which dip
Host rocks for the upper parts of the ore zones are the Upper Cretaceous sediments
and the volcanic rocks in the richer lower Jurassic terrigenous deposit.
Mineralisation along strike and dip ranges from tens to several hundreds of meters.
Thickness from 0.2 – 18.0m, average: 4.4m.
Ore zones are similar in material composition and represented by the same mineral
assemblages: quartz-tourmaline, quartz-cassiterite, quartz- sulphide, and supergene
assemblages. Mineralisation is very similar to other regional tin deposits: cassiterite,
chalcopyrite, arsenopyrite, wolframite, pyrite, cellular-pyrite
Oxidized ores account for 9.4% of C1+C2 resources. 85-90% of tin is presented by
cassiterite, mainly quartz associated which is concentrated in the lower structural
floor of Jurassic sandstone and shale. The Cassiterite contained in the developed
sulphide mineralization in the upper floor of the cretaceous volcanites is corroded by
sulphides and led to the formation of stannite and hydro-stannite. The principle
associated minerals are copper and tungsten.
The ore types in the Sable Tin license have analogues in the other mined deposits of
Komsomolsk region, thus, simplifying the solution of technological problems The
textural and structural features of ore from the Sable Deposit also provide higher
recoveries than ores from neighbouring deposits.

Sable Tin Resources is currently acquiring the historical documentation related to the
Sable Tin Deposit after which digitalised models will be created using the historical
data. Subsequently the company will prepare a confirmation drilling program to be
designed on processed historical data.
