1. Yanxi Copper Project - Hami, Xinjiang, PRC
Copper

Location & Access

The Yanxi Copper Deposit is located about 115 km southwest of Hami, a city in the eastern part of Xinjiang of China. The Exploration Right is registered under the name of Tongxing and covers an area of 21.67 km2. The property is centered at about 92°28' east longitude and 42° 05' north latitude.

The property has a fairly good accessibility. Main routes, namely National Highway 312 and Lanxin Railway (兰新铁路), are situated at about 80 km north to Yanxi property, while Hami-Luobubo Highway (哈密-罗布泊公路) passes through the property for 120 km. The nearest airport is located at Hami.This domestic airport was expanded and re-commenced operation in December 2008 and has connecting flights to Urumqi airport, which is about 595 km west of Hami. Urumqi airport is an international airport and has regular air service to Beijing, Shanghai and other Chinese cities. Hami City is also connected to Urumqi by a sealed highway that is presently being upgraded. Typically, the highway is divided, with two or three lanes in each direction. There is also a reliable passenger rail service between Urumqi and Hami City.

Geology & Mineralization

The property geology consists of three main Carboniferous rock types: basic to intermediate mafic volcanic and volcaniclastic rocks; a unit composed of clastic sediments, tuffs and brecciated lava; and a pebbly arenite unit.

The rocks are mapped as east-west striking, steeply south-dipping and broadly southfacing units. The supracrustal rocks are variously intruded by porphyritic diorite and granitic rocks and some mafic intrusive rocks, predominantly gabbros. Mineralization on the property is hosted in a plagioclase porphyritic granodiorite intrusive with an irregular dike-like shape. The intrusive is up to 200 m wide, strikes broadly east-west and dips south at about 70°.

The Yanxi deposit is considered to be an example of porphyry copper deposit type and is located in a regional belt of copper deposits. Further, the mineralization is not exposed on the Yanxi property because of the presence of Jurassic sediments unconformably overlying mineralization.

The economic mineralization at Yanxi is predominantly hosted in the plagioclase porphyritic granodiorite intrusive.

NI 43-101 Resource Estimate

Based on the 31 diamond drill hole results up to 10 September 2008, GobiMin announced an initial NI 43-101 compliant resource estimate on Yanxi Copper Project in October 2008. The estimate of the metal content is shown in the table below:

Mineral Resources - Yanxi Copper Deposit
Classification Million
tonnes
Cu
(%)
Copper (contents)
lbs
Indicated 15.38 0.75% 254 million
Inferred 10.23 0.71% 160 million

Notes:
  1. CIM definitions were followed for Mineral Resources.
  2. Mineral resources which are not Mineral reserves have not demonstrated economic viability.
  3. Mineral Resources are estimated at cutoff grades of 0.5% Cu.
  4. Mineral Resources are estimated using an average long-term copper price of US$2.50/lb, and a US$/Cdn$ exchange rate 1.04.
  5. A minimum mining width of 5 metres was used.

2. Balikun Coal Project - Hami, Xinjiang, PRC
Coal

Location & Access

The Project is located about 265 km from the city of Hami, Xinjiang, China. The mining permit covers about 29.77 km2. The project area is centered about 44°11'00"N, 92°07'23"E. The Boerqiangji Town Charcoal Colliery is about 30 km to the east of the coalfield and is connected by an asphalt road which passes through the coalfield at its eastern boundary.

Geology & Mineralization

The Project (also known locally as Heiyanquan Coalfield) is located in an undeveloped area of the coal rich Balikun coalfield and sits on a plateau consisting of low hills and a relatively flat plain. The elevations, in the immediate area, range from 1,700 m above mean sea level (amsl) in the SW to about 1,550 m (amsl) in the NE, with the terrain generally sloping in that direction. The property is defined by surveyed coordinates used for the 2007 exploration permit, which was replaced by a mining permit in December 2008. There is one mineable seam in the coalfield, namely the "A1", of the Badaowan Formation of Lower Jurassic age, and it appears to be of mineable thickness over 85 to 90% of the coalfield area, with unmineable thicknesses concentrated at depth and in the southern portion of the property. There are regular and predictable fluctuations, based on drilling data and seismic reflections, of thickness and a simple monoclonal structure.

The type of coal found on the property is a high volatile bituminous A coal according to the United States Geological Survey terminology. In China, this same coal is described as gas coal. The 156 Coalfield Geological Brigade (Xinjiang) describes the coal found on this property as gas coal with long-flame coal and weak-glued coal appearing in incidental quantities and isolated locations. The terms "gas coal", "long-flame coal" and "weak glued coal" are local variations of the German coal classification system.

There is one identified mineable seam, namely the "A1", which lies within the permitted area of the Project. The A1 seam has a total thickness ranging from 0.23 to 6.92 m and averaging at 3.30 m. The A1 seam is stable and has regular and predictable fluctuations of thickness and a simple structure. From a coal quality viewpoint, the A1 coal is at a low metamorphic stage and is mainly a gas coal, with the quality properties of very low-high ash, low-very high calorific value, very low-mid-high sulphur, low-high phosphorus and eutectic-dystectic ash, which can be used for coke making.

The 156 and 161 Coalfield Exploration Brigades of the Coalfield Geological Bureau of the former Xinjiang Coal Industry Administration and the No. 1 Regional Survey Brigade of Xinjiang Geological & Mineral Bureau have conducted extensive surveys since 1958. The locations of coal seam outcrop were discovered by a pre-survey, reconnaissance, detailed survey and interpretation of concealed coal seams by 2-D seismic survey in 2006. A total of 31 boreholes (8 for extensive-detailed survey [2006], 23 for exploration [2007]) were completed, for a total of 11,702.69 m (including mechanical core drilling of 3,168.04 m [2006], 6,808.35 m [2007] and hydrological drilling of 1,043.87 m, 682.43 m in 2006 and 2007, respectively). In November 2007, the report summarizing in detail the results of the 17-month, two-part program (reconciliation and initial survey in 2006 and detailed survey in 2007) was issued by the 156 Brigade.
