Entrée Gold Begins Exploration At Sol Dos, Arizona;
Copper And Molybdenum Intersected At Manlai, Mongolia

September 13, 2006

Vancouver, B.C., September 13, 2006 - Entrée Gold Inc. (TSX: ETG; AMEX: EGI; Frankfurt: EKA – “Entrée” or the “Company”) reports on its exploration activity. Sol Dos Prospect, Arizona

Entrée has commenced exploration of the Sol Dos copper prospect, in the Safford area of south-eastern Arizona. A geophysical crew has been mobilized onto the property to commence a 20 line kilometre program of deep probing induced polarization (“IP”) and magnetic surveys. Entrée has an option to earn a 100% interest in Sol Dos, subject to a 2% NSR royalty, half of which can be purchased by Entrée.

The Company plans to drill targets outlined by the IP and magnetometer surveys, later this fall. The prospect is modeled as a large porphyry copper target, similar to the San Juan and Dos Pobres deposits, being developed by Phelps Dodge, approximately 8 kilometres (5 miles) to the northwest, and to the deep, high-grade Resolution porphyry copper deposit, being evaluated by Rio Tinto and BHP Billiton, approximately 100 kilometres (60 miles) to the northwest.

Lookout Hill Project, Mongolia
Two diamond drill holes, totalling 2,221 metres, have now been completed by Entrée immediately west of Ivanhoe Mines Ltd.’s (IVN:NYSE, TSX, NASDAQ – “Ivanhoe”) Oyu Tolgoi concession. The holes targeted coincident IP and copper-in-soil anomalies, in or close to assumed Devonian rocks in Entrée’s West Grid area. Drilling and exploration were hampered by technical problems and unusually heavy rainfall.

Hole EG06-040 intersected a 31 metre zone (250 - 281 metres) of sheared and altered Devonian (?) basalt averaging 370 parts per million (“ppm”) copper, including a 3.68 metre (250.0 - 253.68 metres) interval averaging 0.17% copper. Another shear zone, separating Carboniferous basaltic tuffs from Devonian volcanosedimentary rocks, was intersected at a down-hole depth of 435 metres. However, the strong IP anomaly in this area remains unexplained and is being tested at a greater depth in a third hole, EG06-041, which is in progress. Approximately 5,500 metres of budgeted diamond drilling remain to be completed this season. Two additional deep diamond rigs from Major Drilling are mobilizing to the Lookout Hill property within the next two weeks.

A total of 3,290 metres, in 18 holes, of shallow reverse circulation drilling was completed in the areas of the Zone III epithermal gold target and the Zone I and Ring Dyke epithermal/porphyry- style targets. Results from this drill program are pending. Entrée – Ivanhoe Earn-in Agreement Area

Ivanhoe continues condemnation drilling on the Earn-In Agreement portion of Entrée’s Lookout Hill project. The drilling is designed to verify the absence of significant mineralization in areas of proposed infrastructure development. Ivanhoe is continuing with its development plans for Oyu Tolgoi and is advancing its mine plan. Studies include the continued evaluation and development of Entrée’s Copper Flats area, where an inferred resource, traced over a strike length of 625 metres north of the Entrée-Ivanhoe property boundary, is estimated to contain over 6.5 billion pounds of copper and 3.2 million ounces of gold. The mineralized system that defines the northward continuation of Ivanhoe’s Hugo Dummet ore body onto Entrée’s Copper Flats ground remains open along-strike to the north. Mineralized drill intercepts occur 600+ metres north of the currently defined inferred resource, and the structural system hosting the Hugo Dummett mineralization extends for an additional eight kilometres north on Entrée’s Lookout Hill property.

Manlai Project, Mongolia
Since the beginning of the current exploration season, a total of 3,108 metres of diamond drilling, in six holes, has been completed. Drilling this year (holes EGU06-005 to EGU06-010) has been concentrated in the area of a large (1.5 kilometre x 1.5 kilometre) IP chargeability – magnetometer anomaly, with associated porphyry-style alteration and mineralization. This anomaly was not tested in the 2005 exploration season.

Hole EGU06-009 intersected a broad zone (215 metres down-hole length) of variable quartz stockwork with visible copper and molybdenum sulphides in association with numerous porphyritic dykes. A similar quartz stockwork with copper and trace molybdenum sulphides was encountered in hole EGU06-010. The hole is located approximately 250 metres southeast of hole 009 and lies midway between holes 009 and 005 (see map on Entrée’s website at

In hole EGU06-005, a zone of moderate to strong pervasive potassic (K-feldspar+/-magnetite) alteration was encountered from 130 to 650 metres (end of hole). Elevated copper values (>250 ppm) occur throughout this zone of potassic alteration with narrower intervals hosting strongly anomalous copper values (see table below). Results from holes 008, 009 and 010 are pending.

Thickness (metres)

Average copper value (ppm)


401.5 – 419.9



438.8 – 537.2






474.0 – 484.0



547.0 – 584.0






547.9 – 556.0



Holes EGU06-006 and EGU06-007 were collared approximately 500 metres to the east of hole EGU06-005 and hole EGU06-008 was collared approximately 750 metres north-northeast of hole EGU05-005. These holes are now interpreted to be too far north and east of the trend of mineralization outlined in holes 005, 009 and 010.

Entrée’s President and CEO, Greg Crowe, commented: “The results of the 2006 drilling on the Manlai project have been encouraging. With only 10 holes to date, the intersection of copper- and molybdenum-bearing quartz stockwork associated with potassic alteration suggests potential for the property to host a porphyry-related mineralized system. The values and alteration encountered so far could represent the margin of a richer system. Every one of the holes put into this zone has encountered a favourable porphyry-style geological environment.”

Mongolian Government Update
The Company is awaiting the official text of recently completed changes to the Mongolian mining legislation. Separately, recent announcements by Ivanhoe indicate a resumption of dialogue between the Mongolian government and Ivanhoe through the establishment of a working group, with the goal of finalizing a comprehensive investment agreement for Oyu Tolgoi (see Ivanhoe news release of Sept. 6, 2006).

Quality Control and Assurance
Exploration programs are under the supervision of Robert Cann, P.Geo., Entrée’s Vice-President, Exploration and a qualified person as defined by National Instrument 43-101. Mr. Cann is responsible for the preparation of technical information in the Company’s news releases. Split core samples were prepared and analyzed at SGS Mongolia LLC in Ulaanbaatar, Mongolia. Prepared standards and blanks are inserted at 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 gold and copper prospects. The Company is a large landholder in Mongolia and has recently acquired an early stage copper porphyry project in Arizona, USA.

Entrée holds a 100% interest in mineral concessions comprising the 179,590 hectare Lookout Hill (Shivee Tolgoi) property which completely surrounds the 8,500 hectare, Turquoise Hill (Oyu Tolgoi) project of Ivanhoe Mines Ltd. (“Ivanhoe”).

Under an “Earn-In Agreement” announced in October 2004, Ivanhoe has the right to earn an interest in approximately 40,000 hectares of Entrée’s Lookout Hill property. Details of the Earn-In Agreement are available on Entrée’s website at and on SEDAR at Drilling conducted by Ivanhoe as part of the Earn-In Agreement has confirmed the extension of the Hugo North Deposit onto Lookout Hill. An initial inferred resource was estimated at 190,160,000 tonnes (calculated using a 0.6% copper equivalent cut-off), averaging 1.91% copper equivalent, containing over 6.5 billion pounds of copper and 3.2 million ounces of gold (see Entrée’s news release of February 1, 2006).

Significant investments by Rio Tinto plc and Ivanhoe have contributed to Entrée’s treasury, which currently exceeds CDN$20 million. Entrée plans to use these funds to explore its wholly-owned projects in Mongolia and Arizona, and acquire and explore new projects globally.

Entrée is listed for trading on the TSX under the symbol “ETG”, on the AMEX under the symbol “EGI” and on the Frankfurt Stock Exchange under the symbol “EKA”.
