VANCOUVER, BRITISH COLUMBIA--(Marketwire - Feb. 27, 2013) - Standard Graphite Corp. (TSX VENTURE:SGH)(OTCQX:DARDF) (the "Company") is pleased to report the positive results from the ongoing metallurgical tests performed by SGS Lakefield on sections of drill core from the first diamond drill program on its flagship Mousseau East Deposit.
Standard initiated metallurgical beneficiation testing at SGS Mineral Services in Lakefield, Ontario to characterize the graphite present on the main portion of the historical deposit. The testing was done through Locked Cycle Tests ("LCT"). These consist in a series of mechanical operations including crushing and grinding to liberate the graphite from the matrix followed by sieving and sorting and assaying of the different fractions to characterize particle size and purity.
Three (3) runs have now been completed on composite drill core samples from the main Mousseau East Deposit. The tests were carried out by gradually increasing the polishing time from 30, 45 and 60 minutes in each sample to evaluate its effects on the final product. The final treatment produced a concentrate with a purity approximating 95% for all large and medium size fractions. The results from the last run (60 minutes) are presented below:

Chris Bogart, President & CEO comments: "We are extremely pleased with these initial results having achieved a commercial product using standard processing methods. Results can be expected to improve further by optimizing and customizing the processing to our material". The three year average value of this blend of graphite concentrates is ~$1400/tonne. This has been calculated using the average of prices tracked by Industrial Minerals using their FCL, CIF European port $/tonne price for medium to large flake graphite concentrate."
SGS Mineral Services also estimated that the rejects would not require post-treatment since they contain sufficient carbonate minerals to buffer any potential acid generating reactions. This testing of the acid generating potential of the rejects is crucial to determine the processing involved during operations. Consequently, the rejects at Mousseau East would require no additional treatment or separation thereby reducing overall costs and environmental hazards.
Fieldwork is expected to resume during the second quarter of 2013 with follow-up diamond drilling on its Mousseau East project aimed at better defining and expanding the historical resource en-route to a N1 43-101 resource.
