PROJECT

Overview

The Sable tin project is a near term development deposit, requiring a confirmation

drilling program.

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

advance.

In 2012 Sable Tin Resources (Zaibaikalsk Mining Company) acquired a 20 year 7.3

km 2 exploration and mining license at a State auction.

Location

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

License coordinates

2 50°56’05 136°31’15 4 50°54’50 136°28’50

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.

Regional Geology

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

mineralization process:

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).

Deposit Geology

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

dioritic porphyrites.

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

more slightly..

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.

Mineralogy

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.

Current work

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.
