Erds Coal Project - JORC Compliant Maiden Resource Statement
Total Indicated and Inferred resource estimate of 807 million tonnes thermal coal
Polo Resources (PRL), the AIM listed mining company with uranium and coal interests in Africa, Australia, Europe and Asia, is pleased to announce a maiden JORC compliant resource estimate for the Erds coal project in Mongolia, operated by its recently established 50:50 joint venture with Peabody Energy Corporation (NYSE:BTU) ("Peabody"). The joint venture was formed to hold all of Polo's coal and mineral interests in Mongolia. The joint venture has 54 licenses throughout the South Gobi and elsewhere in Mongolia which are currently being explored for coal.
The Erds Coal Project adjoins a tenement to the west owned by Gulfside Minerals Ltd who recently announced NI 43-101 compliant resources of 1,185 million tonnes of thermal coal at the Onjuul coal deposit. Polo, through its joint venture company with Peabody Energy, also has tenements (Altanshiree) immediately south of the Gulfside resource and adjoins the Erds resource to the east. The geology of the coal basin, combined with the large thicknesses of coal reported at Onjuul and Erds, strongly indicates that additional coal resources will be discovered at Altanshiree. Drilling is due to commence there this coming month.
The Erds coal project is located in the sub province of Altanshiree of the Dornogovi province. The project is approximately 430km south-east of Ulaanbaatar. It is close to rail and power infrastructure and is around 140km from the border of China. The deposit style for the project is a rift basin, which coincides with the Jurassic-Cretaceous intracontinental rift evolution. Deposits in the project area are hosted in the Huhteeg Formation, which contains thick coal seams. The area has undergone a series of exploration campaigns and the results indicate potential for large scale, multi bench, and open-cut operations.
Micromine designed a resource development programme in order to collect sufficient data of a high enough standard to allow a JORC compliant resource estimate, which was subsequently conducted in May 2009. The programme delivered an estimate for the total Indicated and Inferred resource of 807 million tonnes of thermal coal.
The resource estimation process included performing quality checks on the geological and assay information and modelling coal seam morphology, moisture, ash, volatiles, fixed carbon, sulphur, relative density and specific energy on an air-dried basis. Resource estimation was based on modelling of morphology of the seams by gridding, followed by interpolation of coal quality data and categorisation of resources based upon points of observation.
Boreholes drilled in the 2009 exploration campaign were cored from near surface and all boreholes were geophysically logged to check coal depths and thickness in situ. Coal seam continuity was interpreted from cross sections and nine major seam groups identified with further subdivision into 60 plies. The resource estimate excludes weathered coal (typically 12 to 28 metres below surface) and resources outside the tenement boundary.
Total indicated and inferred rounded resources are estimated as follows:

Analytical work shows that the low rank Erds coal can be classified as "Lignite A" according to the ASTM classification system, or a "Brown Coal" in the Australian classification system. The test work to date suggests the coal would be suitable for mine mouth feedstock for local coal fired power generation.
From a 10kg composite sample for detail testing, indications are that the coal is suitable for power generation with a favourable Hardgrove Index, but high sulphur (1.86%) and moderate ash fusion temperatures (1,150 to 1,300 degrees C).
The geotechnical parameters of the deposit need further assessment. Preliminary observations show sediments overlying the coal have weak rock strength, which may place constraints on potential future pit designs. However, defect spacing and bedding plane shears do not appear to be an issue based on the core logging observations. Overall the Erds coal deposit has very good potential for development into a large scale mine with a low strip ratio, producing a low rank thermal coal product.
Neil Herbert, Managing Director of Polo Resources, said:
"The Erds coal deposit has very good potential for development into a large scale mine with a low strip ratio, producing a low rank thermal coal product for power stations. The project is close to the existing rail network and approximately 140km from the Chinese border. With additional licenses in the area the JV has further potential to expand the resource."

The JV also completed a preliminary exploration programme on a number of its South Gobi licenses during the season now ending but there were no new significant findings to report.

|
Inferred Resource |
that part of a mineral resource for which quantity, grade or quality, densities, shape and physical characteristics can be estimated with a low level of confidence. It is inferred from geological evidence and limited sampling and reasonably assumed, but not verified, geological and grade continuity. The estimate is based on limited information and sampling gathered. |
|
Indicated Resource |
that part of a mineral resource for which quantity, grade or quality, densities, shape and physical characteristics can be estimated with a reasonable level of confidence. The estimate is based on detailed and reliable exploration and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes that are spaced closely enough for geological and grade continuity to be reasonably assumed |
