Longest Lead Time Construction Machinery Lands in Argentina

Vancouver, British Columbia -- Goldrock Mines Corp. (TSX.V -- GRM)

Goldrock Mines Corp. (the "Company" or "Goldrock") is pleased to announce the timely delivery into Argentina of the HPGR, the longest single lead time item for the Lindero project which significantly de-risks the remaining construction and development schedule. The total capital cost of this delivered equipment was CAD$9.35 million.

The Company purchased the Weir Enduron High Pressure Grindings Roll ("HPGR") crusher from Weir Minerals. Weir Minerals is the exclusive minerals market license holder of KHD Humboldt HPGR technology and supply approximately 40% of the HPGR's used worldwide. The purchase included all tooling to install and maintain this equipment. The Company also requested the unit's grinding rolls be equipped with longer 55 mm studs as a result of specific test work studies on typical Lindero rock types. The Company is expecting high equipment availability with a rolls life of between 11,000 and 13,000 hours before a change out is required. The HPGR is being stored in Cordoba until required during construction.
The HPGR's specially designed, energy efficient crushing technology has been well established in the cement industry for decades. The application has successfully expanded to harder and more abrasive rock types including copper, gold, platinum and iron ore processing. In October 2009, the first commercial HPGR was commissioned for a heap leach gold operation at Goldfields' Tarkwa Mine, Ghana. Currently, Golden Queen is installing a HPGR at its Soledad Mountain heap leach project in California. The machines are compact and generate low levels of noise and vibration. The advantages of HPGRs include the following:

• higher throughput capacity per unit than other types of crushing units to achieve same size reduction ratio;
• better particle size fraction curves for same power input;
• potential energy efficiency achieved through lowered energy losses and more stable energy use;
• smaller processing plant layout and structural footprint with respect to belts and classifiers required;
• higher equipment availabilities due to stud and liner technology; and
• potential for greater gold leaching efficiency due to the production of micro-fractures in the crushed particles.

Paul Matysek, President and CEO of the Company, commented "With the HPGR unit delivered into Argentina, the Company is positioning for a smooth transition into full construction. Having the key single longest lead time item ready in-country for installation, significantly de-risks the remaining construction and development schedule deliverables for the Lindero project."
