Sierra Resource Group, Inc. Acquires Chloride Copper Mine Project in Arizona

KINGMAN, AZ--(Marketwire - June 21, 2010) -  Sierra Resource Group, Inc. (OTCBB: SIRG ) announced today that it has acquired 80% interest in the Chloride Copper Mine located in Arizona.

The Chloride Copper Mine property consists of 37 unpatented lode mining claims and 12 millsite claims. It is located 24km northwest of Kingman, in the Wallapai District, Mohave County, Arizona. The open pit mine and the existing SXEW processing plant operated at the site from 1995 before being idled in 1996 due to low copper prices.

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.

The NI43-101 Report estimates that Chloride Copper Mine contains an indicated resource of 2.22 million tons grading 0.625% TCu (total copper) at a cut-off grade of 0.03% TCu and 10 ft. minimum vertical thickness (27.5 million pounds of copper).

Sierra Resource Group Announces Initial Assay Results of Tailings Impoundment Drill Program at Its Chloride Copper Mine Property.

PRWeb –  Mon, Oct 24, 2011

Sierra Resource Group, Inc. (OTCBB: SIRG) announced today that the Company has received initial assay results from its drill program on the tailings impoundment at its Chloride Copper Mine Property (formerly known as the Emerald Isle Mine) near the town of Chloride , in Mohave County Arizona .

Kingman, AZ (PRWEB) October 24, 2011

Sierra Resource Group, Inc. contracted ALS Minerals of Reno Nevada to complete the testing of its Tailings Drill program. Drill and Assay results from ALS ICP-33 Element test use the ME-CEP61a Method and results showed:

• 
  

  Copper grade ranged from a minimum of 0.16% Cu ppm to a maximum of 0.43% Cu ppm with the average being 0.36% Cu ppm.

  
  


• Magnesium averaged 0.63% Mg %.


• Zinc averaged 0.32% Zn ppm.

Eight (8) gridded vertical holes were drilled using an auger drill rig. Samples were then taken at intervals of ten (10) feet and were continue to the tailings/surface contact. There was a total of 28 samples. Samples were placed in polyethylene bags secured with “zip ties” for transport. All tailings samples were analyzed by the ISO 9001-accredited ALS Minerals Laboratory in Reno, Nevada. Samples were tested for bulk specific gravity, assayed for 33 element ICP and Cu oxide/cyanide leach ability.
The objectives of this drill program were designed to collect material in order to confirm the grade of copper mineralization that was previously reported by SGV Resources Inc. The copper distribution appears to be consistent over all the samples collected from the tailings impoundment.
The tailings are the waste product from the previous operation of the Emerald Isle Mine from 1943 to 1973 when copper recovery was much lower than today’s recovery rates. This low recovery indicates that a substantial amount of copper-bearing material was sent to the tailings impoundment. The objective of this analysis was to determine whether the tailings could be economically mined and processed to recover the contained copper in them.
