Heruga Continues to Grow; 0.80% CuEq over 590 metres drilled at the Heruga Deposit in Mongolia

April 25, 2012

Vancouver, B.C., April 25, 2012 – Entrée Gold Inc. (TSX:ETG; NYSE-Amex:EGI; Frankfurt:EKA - "Entrée" or the "Company") reports that core hole EJD0034A has intersected 590 metres of 0.33% copper, 0.70 grams per tonne (“g/t”) gold and 56 parts per million (“ppm”) molybdenum, or 0.80% copper equivalent (“CuEq”), at the Heruga deposit.  The hole is a wedged offset of EJD0034 (686 metres of 0.36% copper, 0.67 g/t gold, and 79 ppm molybdenum or 0.83% CuEq), and was drilled to test mineralization downdip and approximately 150 metres to the east of the end of EJD0034.  The hole was drilled by joint venture manager Oyu Tolgoi LLC (“OTLLC”) on the Entrée-OTLLC joint venture property in Mongolia.  A drill plan and section are posted on

Greg Crowe, President and CEO commented, "This hole is significant because it extends the known limit of mineralization for this section of the deposit by 150 metres to the east and 150 metres deeper.  It also supports the working theory that gold grades increase to the east and at depth along the Oyu Tolgoi mineralized trend.  We believe Heruga represents a considerable blue-sky development opportunity for Entrée and our joint venture partner, OTLLC.”

Table 1. Summary of drill intercepts from EJD0034A


*CuEq estimated using US$1.35/pound (“lb”) copper (“Cu”), US$650/ounce (“oz”) gold (“Au”) and US$10/lb molybdenum (“Mo”). The equivalence formula was calculated assuming that gold and molybdenum recovery was 91% and 72% of copper recovery respectively. The contained gold, copper and molybdenum in the tables have not been adjusted for recovery.

Recent exploration drilling within the Oyu Tolgoi mining complex has been testing for gold and bornite-rich copper mineralization along the east flank of the Oyu Tolgoi trend.  A general pattern has been noticed along the trend wherein gold grades increase to the east and at depth.  A previous hole (EJD0045), located to the southeast of Heruga, was drilled late in 2011 to test this pattern.  This hole did not meet the intended target due to faulting.

Hole EJD0034A was wedged off hole EJD0034, with the intent of testing the area to the east and below hole EJD0034.  EJD0034A is the first hole to successfully test the eastern flank of the Heruga deposit for this style of mineralization within the Javhlant license.  The deepest mineralized intercept from 1,740 to 1,794 metres contains 0.28% copper, 1.87 g/t gold and 6 ppm molybdenum (1.48% CuEq) over 54 metres (Table 1).  The hole also crossed fewer post-mineral dykes than EJD0034 and extends mineralization another 150 metres below the previous limit of mineralization in EJD0034. Heruga remains open to the east and to depth.

The Heruga copper-gold-molybdenum deposit hosts an inferred mineral resource of 910 million tonnes grading 0.48% copper, 0.49 g/t gold and 141 ppm molybdenum for a CuEq grade of 0.87%, using a 0.60% CuEq cut-off grade, and is estimated to contain approximately 9.5 billion pounds of copper and 14 million ounces of gold.

On the joint venture property, the Heruga mineralized system extends from the northern licence boundary south for 2.2 kilometres and shallows from a vertical depth of approximately 1,000 metres below surface to 500 metres.  The deposit has a vertical extent varying between 400 to 800 metres and a width of 200 to 450 metres.  Mineralization extends north onto the Oyu Tolgoi licence (100% OTLLC) where it is known as Heruga North. Entrée has a 20% carried interest in the Heruga deposit, which forms part of the Oyu Tolgoi mining complex.  Heruga is not included in the current phase 1 mining plan, but is included in the longer term Life of Mine (Sensitivity) Case discussed in the recent Lookout Hill Technical Report available on SEDAR at (see news release of March 30, 2012).

A drill rig is currently testing a similar target to the southeast of Heruga on the joint venture property.


SGS Mongolia LLC prepares the split core at the project site and assays all samples at its facility in Ulaanbaatar, Mongolia.  OTLLC’s QA/QC program is managed on site by OTLLC.  In-house, matrix-matched copper-gold-molybdenum standards, duplicates and blanks are inserted at the sample preparation lab on the project site to monitor the quality control of the assay data. Drill intersections described in this news release are based on core lengths and may not reflect the true width of mineralization.

Entrée Gold Inc. is a Canadian mineral exploration company focused on the worldwide discovery and development of copper and gold prospects.  The Company has significant interests in three key copper porphyry deposits:  the Hugo North Extension and the Heruga deposits in Mongolia, and the Ann Mason deposit, located near Yerington, Nevada.

The Lookout Hill property in Mongolia completely surrounds the Oyu Tolgoi mining license held by OTLLC, a subsidiary of Ivanhoe Mines and the Government of Mongolia.  A portion of Lookout Hill (Shivee West) is 100% owned by Entrée.  The remainder is subject to a joint venture with OTLLC.  The joint venture property hosts the Hugo North Extension copper-gold deposit and the Heruga copper-gold-molybdenum deposit.  The deposits are included in the larger Oyu Tolgoi mining complex – Rio Tinto is the project manager.  Excellent exploration potential remains on the property for the discovery of additional mineralized zones.

In North America, the Company is exploring for porphyry-related copper systems in Nevada, and New Mexico.  The primary North American asset is the Ann Mason Project near Yerington, Nevada.  The Ann Mason Project has considerable potential, both to increase the size of the Ann Mason deposit and to discover additional targets.

In addition to being a politically stable jurisdiction and close to infrastructure, the Yerington copper camp has seen significant historic copper production along with a resurgence of exploration activity and now hosts over 20 billion pounds of copper in a number of separate deposits owned by several unrelated companies. 

Rio Tinto and Ivanhoe Mines are major shareholders of Entrée, holding approximately 13% and 11% of issued and outstanding shares, respectively.  Rio Tinto, by virtue of its majority ownership of Ivanhoe Mines, beneficially owns 23.6% of Entrée’s issued and outstanding shares.
