About the company:

Sierra Resource Group, Inc. (OTC Bulletin Board: SIRG) is a U.S.-based exploration and mining company committed to the exploration, discovery and development of gold, silver, copper and other mineral resources. Sierra's primary asset is 80% ownership of the Chloride Copper Mine located near Kingman, Arizona . Sierra has reached an agreement to purchase half of the minority interest taking its overall ownership to 90%. The technical report, NI43-101, by Scott Wilson Roscoe Postle Associates March 10, 2006 , estimates the Chloride Copper Mine contains 27,000,000 pounds of copper. The company is looking to expand throughout the Americas in the near future.

Sierra plans to use open pit mining and plans to reopen the existing SX/EW Plant On-Site with the maximum capability of producing up to 5,400,000 pounds of Copper Cathode per year. The existing SX/EW Plant On-Site is environmentally friendly, cost effective and a quick production process according to an article published by the Copper Development Association in August 2001 .

The Chloride Copper Mine deposit is hosted by Late Tertiary conglomerates and, to a lesser extent, by Quaternary alluvium and Cretaceous granitic rocks. Copper mineralization at Chloride Copper Mine is in the form of mineralized lenses contained within a paleochannel approximately a few thousand feet long and up to 750 feet wide. The source of copper at Chloride Copper Mine is interpreted to be the low grade porphyry-type copper mineralization at Alum Wash, about 3.5 miles northeast of the Chloride Copper Mine deposit. The mineralization is characterized by dark blue to black rock similar to the Exotica deposit, a satellite of the huge Chuquicamata copper deposit in Chile .

Sierra's management and Board of Directors consist of expert geologists, mining professionals and experienced business people.
