ROCKHAVEN RESOURCES LTD. UPDATES ITS MILL CITY GOLD CORP. TRANSACTION

June 23, 2011 - Rockhaven Resources Ltd. (TSX-V:RK) ("Rockhaven") is pleased to announce, further to its April 12, 2011 and June 14, 2011 news releases, that it has been issued 16,671,332 common shares of Mill City Gold Corp. (“Mill City”) pursuant to its Mount Hinton property option agreement, under which Mill City can earn a 100% in the Mount Hinton property located in the Keno Hill mining camp in central Yukon Territory. Mill City can exercise the option by making staged payments totaling $5.16 million by December 31, 2014 and by the issuance of these 16,671,332 common shares to Rockhaven. Rockhaven will also retain a 2% net smelter return royalty interest in the property.

Prior to the closing of the option transaction, Rockhaven did not hold any Mill City shares. The 16,671,332 Mill City common shares acquired by Rockhaven at closing represent 19.9% of Mill City’s issued capital following the closing. All of these shares will be held directly by Rockhaven and are being held for investment purposes. Rockhaven may in the future take such actions in respect of its Mill City shares as it deems appropriate in light of the market circumstances then existing, including the potential purchase of additional shares of Mill City through open market purchases or privately negotiated transactions, or the sale of all or portion of such holdings in the open market or in privately negotiated transactions to one or more purchasers.
