Initial Public Offering
Castle Silver Mines is effecting an initial public offering of 4,750,000 "flow-through" units at a price of $0.40 per unit, and a minimum of 3 million and a maximum of 5 million common share units at a price of $0.30 per unit, for maximum gross proceeds to Castle Silver Mines of $3.4 million. Each "flow-through" unit will consist of one common share of Castle Silver Mines and one-half of a common share purchase warrant. Each common share unit will consist of one common share of Castle Silver Mines and one common share purchase warrant. Each full warrant will entitle its holder to acquire one additional common share of Castle Silver Mines at a price of $0.50 for a period of 18 months.
The proceeds from the initial public offering will be used by Castle Silver Mines for exploration work on its Castle Silver Mine property, future property acquisitions and for working capital and general corporate purposes. A description of the recommended exploration program for the Castle Silver Mine property is summarized in the final prospectus, which is available under Castle Silver Mines' company profile on SEDAR at www.sedar.com.
The TSX Venture Exchange has conditionally approved the listing of the common shares of Castle Silver Mines, subject to, among other standard listing conditions, completion of the initial public offering for minimum gross proceeds of $2.8 million with satisfactory public distribution.
Industrial Alliance Securities Inc. is acting as agent for the initial public offering on a "best-efforts" basis. Castle Silver Mines has granted Industrial Alliance Securities an option to offer up to 750,000 additional common share units and up to 712,500 additional "flow-through" units, representing 15% of the number of units offered, to cover over-allotments, if any. The over-allotment option may be exercised at the offering prices for a period of 30 days from the date of closing of the offering. If Industrial Alliance Securities exercises the over-allotment option in full after a maximum offering, the total gross proceeds of the offering will be $3,910,000.
Closing of the initial public offering is expected to take place no later than December 15, 2011.

Castle Silver Mines Inc.
Castle Silver Mines Inc. was incorporated in March 2011 as a wholly-owned subsidiary of Gold Bullion, for the purpose of taking over the silver assets and exploration activities currently carried on by Gold Bullion, so that Gold Bullion can devote itself solely to exploration for gold.

After such transfer, Gold Bullion does not intend to be directly involved in silver exploration. Castle Silver Mines may acquire additional interests in silver exploration properties in the future.
