Orestone Mining Corp. (TSX Venture Exchange–Symbol: ORS) (“the Company”) announces that the Company will hold an annual general meeting of the shareholders (the “Meeting”) on Monday, September 10, 2012. In addition to the annual matters to be acted upon, as set forth in the Notice of the Meeting dated August 13, 2012, the Company will seek shareholder approval to consolidate the Company’s common shares (“Common Shares”) on the basis of one

(1) post-consolidation Common Share for every four (4) pre-consolidation Common Shares or at such lower consolidation ratio as may be required by the TSX Venture Exchange (the “Share Consolidation”).
