METALLURGICAL TESTING UNDERTAKEN ON A HIGH GRADE GOLD SAMPLE OF AQUILON

MONTRÉAL (QUÉBEC) – RESSOURCES SIRIOS INC. and joint venture partner Golden Tag Resources Ltd. are in the process of completing a metallurgical testing on a composite high grade gold sample from the Lingo vein on the Aquilon property in James Bay, Quebec. The composite sample of 92kg consists of half core samples from the drilling that took place on the Lingo vein in 2008 and 2009. The purpose of the test is to establish an average grade, and as well to specify the granulometry that will lead to a satisfactory gold recovery by simple gravimetric concentration. The test is being conducted by L.T.M. Laboratory of Val D’Or, Quebec and is a first step toward initiating procedures to obtain required permitting in order to conduct a bulk sampling of the Lingo vein. For more information on the AQUILON project, please visit the Company’s website and refer to the 2009 May 6, Press Release.
