On January 25, 2012, representatives of Rizzo Associates completed a site visit of the Chloride Copper Mine. The Rizzo Associates team consisted of Dr. Ananda (Andy) Chakrabarti, Senior Consultant, and K. Michael Cline, Principal Geologist. The purpose of the site visit was to provide an independent assessment of the plant, mill tailings, and general site conditions for supporting the Company in bringing the existing SX/EW Plant at the Mine back into full operation. The Plant has been idle since 1996. 

On February 21, 2012, Rizzo Associates issued a "Trip Letter Report to Assess Status of the Chloride Copper Mine" to the Company.  According to the "Trip Letter Report: "The SX/EW Plant is in good condition; however, in need of minor refurbishment and the replacement of some supporting equipment, but most of the equipment can be used and the Plant can be brought back into working condition within a reasonable timeframe and limited expense."  The Company has not currently defined "reasonable timeframe" or "limited expense."

"We are extremely pleased to have the Rizzo team working to bring the mine back into production and beginning work to improve the accuracy of our reserve estimate," says J. Rod Martin Chief Executive Officer of the Company.

About Sierra Resource Group Inc.:

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. The technical report, NI43-101, by Scott Wilson Roscoe Postle Associates dated March 10, 2006, estimates the Chloride Copper Mine contains 27,000,000 pounds of copper. The company is looking to expand throughout the Americas.

Sierra plans to use open pit mining and plans to reopen the existing SX/EW plant on site with an estimated maximum capability of producing up to 5,400,000 pounds of Copper Cathode per year. The SX/EW process is environmentally friendly, cost effective and a quick production process according to an article published by the Copper Development Association in August 2001 and publically available on the Association's website (www.copper.org).

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 geophysicists', mining professionals and experienced business people.
