MONTREAL, QUEBEC--(Marketwire - Aug. 20, 2012) - KHALKOS EXPLORATION INC. ("Khalkos") (TSX VENTURE:KAS) and SIRIOS RESOURCES INC. ("Sirios") (TSX VENTURE:SOI) have cancelled the agreement announced on July 26 concerning Sirios' gold property Hipo, located in James Bay, Quebec. Both Boards of Directors judged that it would be more beneficial for each company to cancel the transaction.

The Hipo property consists of 63 claims separated in three non-adjacent blocks located at around 50 km south of the LG-4 hydroelectric complex in James Bay, Quebec. The property is centered on a volcano-sedimentary belt that has undergone little or no exploration until now.

Neither the TSX Venture Exchange nor its Regulation Services Provider (as that term is defined in the policies of the TSX Venture Exchange) accepts responsibility for the adequacy or accuracy of this release.
