Tin:

C1:46,872kt (grade:1.07%); C2: 45111kt(grade:0.74%)

Geological features:

The mining area is located in slope vally bottom of Thamanit river. The permitting mining zone is between 220-564m in altitude.

Climatic features: dry and chill in winter (minimum temperature: -40-43℃)；

rainy and warm (maxium temperature is +35℃), annual average temperature: -2.5℃

The company bid the prospecting and mining licence of the tin ore as well as it’s associated components in December 2012.

Geological condition:

There are 7 middle-large size ore bodies and a lot of small ore bodie in mining area.

All the ore bodies were nervation with apophysis and furcation, most in ladder pattern.

The thickness ore bodies increase and decrease sharply which indicates these   ore bodies are incontinuous. The slope of ore bodies change from small-angel to right-angel.

Big size ore bodies are mainly located in Leningrad、Suobolinuo、East area、and Nieridan.

Smaller ore bodies are mainly in central part and Novosibirsk.

The whole ore area is 1.3×1.5km2.

Engineering geological condition:

engineering geological condition is very favorable for steep and incline ore body development. Wall rock is with good stability whose average hardness is 10.

Development potential:

There are a lot of small size ore bodies in Suobolinuo mining area which have great growth potential in resource reserves. These small size ore bodies were found by drilling during prospecting. 

It is predicted that there is a tin mineralized region in the south of mining area. That is to say there are undiscovered ore bodies in the south.

Predicted reserves of Level P1: 20.4 thousand tons. Gross reserves may increase by 20% in the future.

Some signs around the mining area indicate exist of similar ore bodies.

Inclined hole:529(drills)

Diameter of drill pipe: 59mm (40.7%), 76mm (56.1%)

Total footage: 230.8km.

Transversely go through the ore body trend: 388.2 thousand m³.
