Celsius Coal (ASX: CLA) has confirmed the high potential for coking coal from its Kargasha deposit in the Kyrgyz Republic to be beneficiated.
The company has received results from the laboratory float/sink testing of 26 samples of Kargasha coking coal and coal composites with raw ash of greater than 10%.
The material appears to beneficiate with well-defined density cut point of 1.5g/cc.
Using this cut point theoretical yield ranges from 41% to 94%, with 84% of values being greater than 60%. Theoretical yield has a strong correlation with raw (head) ash.
The test work has resulted in a very low ash (on an air dried basis) product with ash ranging from 2.5% to 9.4%, with over 40% of values being between 5% and 6%.
The washed product shows a free swell index consistent with coking coal, ranging from 6.5 to 8.5 and 64% of values being equal to or greater than 7.
Celsius is now progressing further testing to analyse for phosphorous, sulphur content, ash composition, ultimate and more extensive coking properties.
The Kargasha deposit forms part of the Uzgen Basin Coal Project, which also comprises the Kokkia and Min Teke deposits.
Celsius has outlined an exploration target of 501 million to 700 million tonnes of coal for the Uzgen Basin Coking Coal Project.
The company it is on track to deliver a maiden JORC coal resource in the first quarter of 2013.
