Entrée Defines NI 43-101 Inferred Resource of 7.1 Billion Pounds Copper at Ann Mason, Nevada

January 26, 2010

Vancouver, B.C. - Entrée Gold Inc. (TSX:ETG; AMEX:EGI; Frankfurt:EKA – “Entrée” or the “Company”) has received the first National Instrument 43-101 (“NI 43-101”) compliant resource estimate prepared for the Ann Mason copper- molybdenum deposit located near Yerington, Nevada. Ann Mason is estimated to contain an inferred resource of 810.4 million metric tonnes grading 0.40% copper, using a 0.30% copper cut-off (see Table 1 below). Accompanying molybdenum is estimated at 165.9 million metric tonnes at a grade of 0.01% molybdenum. Based on these figures, the Ann Mason deposit contains approximately 7.1 billion pounds of copper.

Entrée commissioned Wardrop Engineering Inc. (“Wardrop”) to prepare the NI 43-101 compliant Technical Report and Resource Estimate of the Ann Mason Copper Molybdenum Project (“2010 NI 43-101 Resource Estimate”), which is filed on SEDAR. This independent report was completed in order to fulfill Canadian regulatory requirements.

The Wardrop 2010 Inferred resource is confined by an optimized Whittle pit shell #25. Using the same pit shell, the 2010 Inferred resource estimate represents a 10.6% increase in tonnes from the 2006 model (724.7 million tonnes at 0.40% copper) with a negligible increase in grade at a 0.30% copper cut-off. The increase in tonnage is largely due to the inclusion of additional information generated by drilling after the 2006 calculation was made.

Entrée announced on November 29, 2009 that it had signed a definitive agreement with PacMag Metals Limited (ASX:PMH – “PacMag”) to implement Australian Schemes of Arrangement to acquire all of the issued shares and options of PacMag. PacMag has a 100% interest in the Ann Mason Project, which hosts the Ann Mason deposit. PacMag commissioned Golder Associates (“Golder”) to prepare a Joint Ore Reserves Committee (“JORC”) compliant resource estimate in 2006 that outlined an in-situ Inferred Mineral Resource of 810 million tonnes grading 0.40% copper and 0.004% molybdenum at a 0.30% copper cut-off grade, estimated to contain more than 7.1 billion pounds copper. The 2010 NI 43-101 Resource Estimate confirms the 2006 Golder estimate.

Greg Crowe, President and CEO of Entrée commented, “The recent NI 43-101 inferred resource calculation validates the earlier work done by PacMag, and suggests there is significant scope to expand the deposit by further drilling. Once the merger with PacMag is complete, we intend to commence a substantial exploration program, including additional drilling to potentially expand the resource and to further test the southern and western portions of the Ann Mason deposit.”

The grades at Ann Mason compare favourably with a number of current producers and development projects in western North America where large open pit porphyry deposits currently in production generally mine copper grades between 0.28 % to 0.56% copper.

In addition to the defined resource, significant copper oxide and deeper sulphide mineralization has been intersected at Blue Hills, approximately 5 km to the west of Ann Mason. The oxide copper target covers an area of 1.5 km by 350 m, and includes near-surface intercepts of 21.3 m of 0.46% copper, 36.3 m of 0.46% copper and 39.6 m of 0.26 % copper. The surface copper anomaly in soils appears to extend to the west onto adjoining ground held by HoneyBadger Exploration Inc. (TSX.V: TUF – “HoneyBadger”), which is under option to Entrée.

At the Shamrock prospect, located 5 km to the southeast of Ann Mason, drilling by PacMag has confirmed the presence of high grade near surface copper mineralization (e.g. 33.6 m of 1.72 % copper) in altered limestone.

Work is also being planned for the contiguous Blackjack and Roulette properties under option agreements with HoneyBadger and Bronco Creek Exploration, Inc. (a wholly owned subsidiary of Eurasian Minerals, TSX.V:EMX). The properties adjoin the Ann Mason property to the west and south.


Entrée Gold Inc. is a Canadian mineral exploration company focused on the worldwide exploration and development of gold and copper prospects. Entrée’s expertise is in exploring for deep and/or concealed ore deposits and with a treasury currently in excess of C$40 million, is well funded for future activities. Ivanhoe Mines and Rio Tinto are major shareholders of Entrée, holding approximately 14% and 15% of issued and outstanding shares, respectively.

Entrée’s flagship property is in Mongolia, where it holds two mining licences and one exploration licence comprising the 179,590 hectare Lookout Hill property that completely surrounds the 8,500-hectare Oyu Tolgoi project of Ivanhoe Mines, and hosts the Hugo North Extension of the Hugo Dummett copper-gold deposit and the Heruga copper-gold-molybdenum deposit.

The Lookout Hill property is subject to a joint venture with Oyu Tolgoi LLC (OTLLC) whereby following expenditure of US$35 million by OTLLC, Entrée now retains a 20% to 30% carried interest through to production, with Entrée’s share of development costs to be repaid from future production cash flow.

The Hugo North Extension deposit hosts a NI 43-101 compliant Indicated resource of 117 million tonnes grading 1.8% copper and 0.61 g/t gold, estimated to contain 4.6 billion pounds of copper and 2.3 million ounces of gold and an Inferred resource of 95.5 million tonnes grading 1.15% copper and 0.31 g/t gold, estimated to contain 2.4 billion pounds copper and 950,000 ounces of gold.  Entrée retains a 20% carried interest in these resources.

The Heruga deposit contains an Inferred resource of 760 million tonnes grading 0.48% copper, 0.55 g/t gold and 142 ppm molybdenum, estimated to contain 8 billion pounds of copper and 13.4 million ounces of gold.  Entrée also retains a 20% carried interest in this resource. 

Both resources were calculated using a 0.6 % copper equivalent cut-off.  The copper equivalent grades were estimated using metal prices of US$1.35 per pound copper, US$650 per ounce gold and US$10 per pound molybdenum.  All resources at Hugo North Extension and Heruga were calculated using a 0.6% copper-equivalent cut-off.

Entrée continues to explore its large landholdings in Mongolia, including the coal discovery Nomkhon Bohr, and is also evaluating the Huaixi copper project in Zhejiang Province in China.

In North America, Entrée is exploring for porphyry-related copper systems in Arizona, New Mexico, Nevada and British Columbia. Entrée’s Nevada property is contiguous with the western boundary of PacMag’s Ann Mason copper project and increases substantially the area of prospective tenure within that district.
