Letter to Shareholders - June 2011

Greenock Resources (formerly Simberi Mining Corporation) is a Canada based international mineral development company that focuses on early to mid stage properties that have a high potential for near term production.

Greenock's primary mineral development project is the Kakanda Copper/Cobalt project  in the Democratic Republic of the Congo ("DRC"). This significant copper/cobalt deposit is localized in the Central African Copper Belt. The Kakanda project has a NI 43-101 compliant report that details significant copper and cobalt resources contained within old tailings and associated hard rock mineralization.  Greenock is seeking joint venture partners to secure final project terms in conjunction with initial deposit of concession payments to Gecamines, the DRC state mining company.

Greenock participates in exploration and develop projects in Australia through property and equity portfolio investments. Greenock has a shareholding in Raisama Pty Ltd., a uranium and base metal company that has a significant property holding in Western Australia. Raisama is listed on the  Australian Stock Exchange (RAI) and has merged plans with Peak Oil and Gas to expand into oil and gas development of a South East Asian property portfolio with an emphasis on a development project in the Phillipines and an exploration program in Thailand.

Greenock has established a US subsidiary company call Arrowhead Gold Inc. to advance exploration and development on Nevada and Arizona gold and silver properties.  The current holding known as the   Needles property is 100% owned by Greenock, is located 60 miles east of Tonapah and was organized in 1919 around the Arrowhead and Arrowhead Extension Mines that produced silver-antimony-gold ore from 1920 to 1939. This early development included sinking the inclined Arrowhead shaft to a depth of 350 feet with drifting on four levels and a 150 foot two compartment shaft with two working levels.

The principal mineral target type sought in the Needles area is epithermal gold, silver and base metals mineralization.  Epithermal gold-silver deposits have been the largest producing deposits in northern Nye County since discovery of silver-rich veins in the Tonopah district in the early 1900's.   The Needles geological setting is clearly analogous in many respects to that of the Round Mountain Au-Ag Mine (Barrick Gold Corp-50%, Kinross Gold Corp-50%) located approximately 65 miles NW of the property. The Round Mountain Mine is a classic epithermal deposit with a high tonnage low grade operation that has produced more than 13,200,000 oz of gold and 11,000,000 oz of silver since 1907; production in 2008 was 520,000oz of gold and 1,000,000 oz of silver.
