AQUILON PROJECT (partnership with Golden Tag): PERMITTING

Required permitting process was started in August with the proper authorities in order to proceed with a bulk sampling programme on the high grade gold showing Lingo. The bulk sampling is planned for winter 2011-2012. Moreover, Sirios now has until June 2012 to complete its work commitment on Aquilon in order to increase its interest from 40% to 50%.

DRILLING ON PONTAX AND PROSPECTING: RESULTS PENDING

Sirios is still awaiting the first core sample assay results from the drilling on Pontax completed in June (see July 13, 2011 press release). The high level activity in the exploration industry is causing long delays for assaying in laboratories. Rock assay results from new projects (Baleine and Koala) are also expected, prospecting on these projects were undertaken in July.
