Rockhaven Resources Ltd. Options Out Mount Hinton Property to Mill City Gold Corp.

VANCOUVER, BRITISH COLUMBIA--(Marketwire - April 12, 2011) - Rockhaven Resources Ltd. (TSX VENTURE:RK) ("Rockhaven") announces that it has entered into an option agreement with Mill City Gold Corp. (TSX VENTURE:MC) ("Mill City"), under which Mill City has been granted the right to acquire a 100% interest in the Mount Hinton property. The property is located in the Keno Hill mining camp in central Yukon Territory and hosts gold-silver-lead mineralization within steeply dipping vein structures.

Under the terms of the agreement, Mill City can exercise the option by: (i) paying Rockhaven a cash payment of $200,000 and issuing to Rockhaven that number of Mill City shares equal to 19.9% of issued Mill City common shares immediately upon regulatory approval; and (ii) making staged cash payments totalling $4.96 million by December 31, 2014, half of which can be paid by the issuance of Mill City shares. The option agreement is subject to the approval of the TSX Venture Exchange.

Rockhaven has retained a 2% net smelter return royalty in any commercial production of precious and base metals from the property. During the option exercise period, Rockhaven will also have the optional right to maintain its 19.9% shareholding by participating in Mill City equity financings.

Rockhaven currently holds its interest in the Mount Hinton property under option from an arm's length exploration syndicate (see Rockhaven news release dated March 8, 2010). In order to exercise its option to acquire a 100% interest in the property, Rockhaven is required to make a final cash payment of $166,000 to the syndicate by March 1, 2012. In a private transaction completed in February of 2011, Rockhaven purchased an underlying third-party royalty interest. Other than Rockhaven's 2% royalty disclosed above, the property is royalty free.

The Mount Hinton property is situated within the eastern part of the Keno Hill mining camp, a district that hosts more than 35 individual mines and is historically Canada's second largest primary silver producer. Although silver mineralization is found in veins on the Mount Hinton property, gold is the most significant component in many of the 72 bedrock showings and float occurrences that have been discovered on the property by previous operators. Creeks draining the property have yielded significant placer gold production and are still being mined.
