Entrée Gold Reports High Copper Recoveries From Its Blue Hill Oxide Target, Ann Mason, Nevada

July 26, 2012

Vancouver, B.C., July 26, 2012 – Entrée Gold Inc. (TSX:ETG; NYSE MKT:EGI; Frankfurt:EKA - "Entrée" or the "Company") reports that metallurgical recoveries ranging from 82.7% to 87.0% have been returned from column leach tests of four crushed drill core composites from the Blue Hill oxide target, located 2 kilometres northwest of the Ann Mason deposit.  The four composites are a combination of oxide and mixed oxide-sulphide mineralization types.  The recoveries averaged 84.8% copper (“Cu”) after a 91 day leach cycle. Compared to other southwestern US copper crushed leaching operations, these results are very favourable. 

Greg Crowe, President and CEO of Entrée commented, “These first copper leach results are extremely encouraging and provide a preliminary indication of the amount of copper that could be extracted from the oxide mineralization at Blue Hill.  These studies complement the sulphide flotation testwork completed to evaluate Ann Mason’s copper sulphide mineralization, which yielded recoveries over 93%, and produced a high quality copper concentrate with no deleterious elements.”

Discussion of Results

Metcon Research of Tucson, Arizona undertook the column leach testing of four composite samples comprised of split drill core from the Blue Hill target.  Three are from oxide-style mineralization, with calculated head grades ranging between 0.13% Cu to 0.25% Cu.  The fourth is from mixed oxide-sulphide mineralization grading 0.17% Cu.  The samples were crushed by Metcon to 80% passing ¾ inch.  From this, 40 kilograms each were loaded into separate 10-foot by four-inch diameter columns.  After a typical agglomeration and a five-day curing process, the columns were initiated on March 13, 2012 using a flow rate of 7.33 litres/hour/m2 and a sulphuric acid concentration of 7 grams/litre.

After a 91 day leach cycle, the columns yielded the above results.  The four composites returned excellent recoveries, ranging from approximately 83% in the mixed composite to 87% in the mid-grade composite.  The average recovery of the four composites is 84.8%.  All composites showed very fast recovery rates with the four columns returning indicated cumulative copper extractions averaging 70% after 15 days of leach cycle.

Preparation of a resource estimate for Blue Hill is underway.  The results, along with the new metallurgical testwork, will be incorporated into the Ann Mason Project Preliminary Economic Assessment, expected to be completed in the second half of 2012.
