MINERAL RESOURCES AND ORE RESERVES

We have four operating manganese mines in China, namely Daxin Mine, Tiandeng Mine, Waifu Manganese Mine And Changgou Manganese Mine. CICMHZ holds the exploration rights covering an area of approximately 2,000 square kilometers in Bembélé area, and the mining rights to Bembe′ le′ Manganese Mine covering an area of approximately 20 square kilometers, which is located within the area covered by the exploration rights.
 
 
 
 
 

Daxin Mine

Daxin Mine was discovered in 1958. Daxin Mine and Tiandeng Mine are located in an area known for abundant manganese mineralization in Guangxi. This region has a subtropical climate with an average temperature of approximately 20 degree centigrade. Annual precipitation ranges from 135 to 192 centimeters. Daxin Mine is located in a mountainous region with elevations of 241 to 845 meters above sea level.
According to the SRK Report, Daxin Mine is the largest manganese mine in China. Daxin Mine and its associated processing facilities are located approximately 50 kilometers west of Daxin County, Guangxi and about 210 kilometers west of Nanning, the capital city of Guangxi. The Daxin Mine area is located at the southeast part of a large scale syncline called the Shangyin-Xialei Syncline, which extends from west to east with its axis dipping east at a very low angle and is about 9 kilometers long and 2 to 2.5 kilometers wide. Three bedded manganese ore bodies, parallel to each other with stable continuity, have been defined in the mine area. Manganese oxide ores occupy the upper part of the ore bodies while manganese carbonate ores are localized in the deeper part of the ore bodies. Manganese oxide ores tend to be more easily and economically extracted compared with manganese carbonate ores. Open pit and underground mining are practiced at Daxin Mine. The open pit operations take place in four mining zones. Our PRC legal advisers have advised us that we have obtained the lawful and valid rights to conduct mining operations within the areas covered by our mining permit with respect to Daxin Mine. We have obtained the land use rights certificates for the area covered by our mining permit for Daxin Mine. As of December 31, 2011, the manganese ore reserves under the JORC Code at Daixin Mine were approximately 72.92 Mt of manganese oxide ore at an average manganese grade of 19.11%.
 
 
 
 
 

Tiandeng Mine

Tiandeng Mine and its associated processing facilities are located approximately 20 kilometers north of Tiandeng County, Guangxi and about 130 kilometers west of Nanning.
The Tiandeng Mine area is located at the south side of the west-east trending Youjiang thrust-fold belt. The ore deposit at Tiandeng Mine was discovered in 1956 and is one of the largest manganese oxide ore mines in China according to the SRK Report. Ten mineralized bodies have been defined at Tiandeng Mine. According to the SRK Report, Tiandeng Mine has large manganese reserves which are shallowly buried and are easy to extract and concentrate. Tiandeng Mine has four open pit mining sub-regions, of which two are in operation. The mineral deposits consist of manganese oxide ores. As of December 31, 2011, the manganese ore reserves under the JORC Code at Tiandeng Mine were approximately 3.92 Mt of manganese oxide ore at an average manganese grade of 15.42%.
 
 
 

 

 

Waifu Manganese Mine

Waifu Manganese Mine is situated at Jingxi, Guangxi, China. As of December 31, the manganese ore reserves under the JORC Code at Waifu Manganese Mine were approximately 1.54 Mt of manganese oxide ore at an average manganese grade of 17.52%.
 
 
 

 

 

Changgou Manganese Mine

Changgou Manganese Mine is situated at Guizhou, China. The mining areas covers an area of approximately 7.2812 km² in Guizhou Province, the PRC. According to a technical report prepared by China Ye Jin Di Zhi Zong Ju Zhong Nan Ju Nanning Di Zhi Diao Cha Suo (中國冶金地質總局中南局南寧地質調查所), the manganese reserve of the covered area amounts to 20,305,500 tonnes in accordance with mineral reserves verification report drafting regulation (固體礦產資源儲量核實報告編寫規定) issued by Guizhou Mineral Reserves Committee (貴州省礦產儲量委員會). As of December 31, the manganese ore reserves under the JORC Code at Changgou Manganese Mine were approximately 22.24 Mt of manganese oxide ore at an average manganese grade of 20.37%.
 
 
 
 
 

Bembe′ le′ Manganese Mine

Bembe′ le′ Manganese Mine and its processing facilities are under development and located approximately 32 kilometers north of Ndjole town in the Moyen-Ogooue Province of Gabon, which is in the central west area of Gabon. The mine area has a typical equatorial rainforest climate with an average temperature of 26 degree centigrade and an annual precipitation between 160 centimeters and 300 centimeters. The mine area is mountainous and located in virgin forests.
The regional geology of Bembe′ le′ Manganese Mine is a simple folding structure, having a gently wavy monocline dipping south-easterly. The mineral deposit consists of mainly manganese oxide ores. SRK is of the opinion that the strata, structure and ore bodies of Bembe′ le′ Manganese Mine had been relatively well investigated with feasibility study already carried out. SRK has inspected the. open pits which show exposure of the ore bodies at Bembe′ le′ Manganese Mine and reviewed the methods used. SRK has reviewed and updated resources/reserve estimation at Bembe′ le′ Manganese Mine in compliance with the relevant standards under the JORC Code. As of December 31, 2011, the manganese ore reserves under the JORC Code at Bembe′ le′ Manganese Mine were approximately 18.26 Mt of manganese oxide ore at an average manganese grade of 31.58%.
