TECHNICAL DUE DILIGENCE

xxxx PROJECT

SEPTEMBER 2014

IMPORTANT INFORMATION ABOUT THIS PROJECT

i. Geological mapping at Ritan and Buluk San area of 1,223 hectares has been conducted by

PT. MIB NUSANTARA, on behalf of PT. xxxx.

ii. The concession area consists of 2(two) formations, which are Batu Ayau and Balikpapan

formation. The coal outcrops that have been identfied during in the field observation

indicated the Batu Ayau formation

iii. 12 (Twelve) coal outcrops representing the 5 coals seam have been observed and taken for

sample analysis.

iv. Drilling activities conducted by PT. XXXX in PT xxxx consist of 23 borehole. Distance before

hole is 100 m until 450 meter.

v. From the all data we got, we try to make some assumtion about caol subsurface modeling

and resources.

vi. All modeling and resources we got, was made by any additional interpretation, that

because we just have limited data.

vii. Really need additional data to proving and covered blank area.

1. PT xxxx covers an area of 1.223 Ha, located at Sub-District, East Kalimantan

Province. This area is a GREEN FIELD and really recomended to do future

exploration.

2. Coal seams is indicated part of Batu Ayau Formation with Late Miocene age.

3. Geological condition STRUCTURALLY MODERATE with gentle dipping 5 – 16 degree

to the North East.

4. Exploration drilling in the North Block has condacted by PT. XXXX . Most recent

holes with total of 23 drillholes Touch Core, NOT SUPPORTED by geophysics log

and only use Jackrow drill with AW pipe size.

5. The deposit is sub-bituminus rank with low ash and medium sulphur.

6. Quality Average

7. The project permitting is summeized below:

Samarinda to Kota Bangun is appoximatly3 hours by land road with car

And continued by boat up to Kahala which take about 4 hours.From Kahala to the site are it take about 3 hour by car

COAL SEAM MODELING AND RESOURCES LIMIT

1. Topography uses SRTM data

2. Coal seam modeling base is limited by 23 drill hole with:

• Maximum depth is 80 m, average depth is 58 m

• Without geophyscs logging

• Power rig drill type with AW pipe size

3. Coal seam modeling base is limited by IUP and model boundary

4. Coal seam modeling base is limited by ‘seam B’. Couple seams just have 2 point

of corellation

5. Resources parameters:

• Maximum and average of drilling depth

• Geophysics logging

• Point of coal seam corelation

CALCULATION SUMMARY

Low confidence on Geology data - Geological database and

geological model are below suitable standard because the drill hole were

not geophysical logging

Multiple thick seam deposit with thin interburden, gentle dipping,

potentially to make big single pits along strike

Additional drilling prior to verification all old data and recovered blank

area, particularly in the sub crop/low wall area
