Entrée Gold Reports Additional Results From Drilling On Javhlant License, Mongolia

October 9, 2007

Vancouver, B.C., October 9, 2007 - Entrée Gold Inc. (TSX:ETG; AMEX:EGI; Frankfurt:EKA – “Entrée” or the “Company”) has received additional results of ongoing drilling on the Javhlant license, Mongolia, from its partner and project operator, Ivanhoe Mines Ltd. (TSX: IVN; NYSE: IVN; NASDAQ: IVN – “Ivanhoe Mines”).  The Javhlant license is included in the joint Entrée-Ivanhoe Mines agreement area.

The drilling program on the area formerly known as Sparrow South, and now called the Heruga Deposit, lies within the north-northeast-trending Oyu Tolgoi structural corridor. The deposit lies approximately 5 kilometres southwest from Ivanhoe Mines’ Southwest Oyu copper and gold deposit.

As announced by Entrée on October 3, 2007, drilling at the Heruga Deposit returned significant initial results in five (EJD0001, EJD0004, EJD0007, EJD0009, EJD0012) of the eleven holes for which results were available at that time. Entrée has now been notified by Ivanhoe Mines that results from a further eight holes have confirmed the discovery of a 1,100 metre-long coherent zone of molybdenum-rich copper and gold mineralization. A zone of gold-rich copper mineralization lies beneath this molybdenum-rich shell.

Results for the eight additional holes are summarized in Table 1.  Hole collar locations are shown on a map posted on the Entree website at

Greg Crowe, President and CEO of Entrée, commented, “In addition to the importance of this discovery, it again confirms the regional nature of the mineralized system associated with Oyu Tolgoi and bodes well for Entrée’s ongoing exploration on its 100%-owned ground to the west of Oyu Tolgoi.”

“Mineralization now extends over twenty kilometres, along the structural trend hosting Oyu Tolgoi.  Our long held belief that significant mineralization could extend onto Entrée’s ground beyond the borders of Oyu Tolgoi has now been confirmed both to the north and south of it.”

The Heruga Deposit was discovered by drill-testing an induced polarization (“IP”) geophysical anomaly that defined a 3 kilometre-long, north-south zone of high chargeability with a width up to 1,000 metres. The anomaly trends north-northeast to the Southwest Oyu Deposit on Oyu Tolgoi. As presently defined, the Heruga Deposit is open to the east and to the south. The IP anomaly indicates that the mineralized zone also may continue to the north and to depth below the early holes drilled on the northern-most section, which now appear to have been stopped short of the mineralized zone.  

Nineteen drill holes (including daughter holes), spaced at 200 to 300 metre intervals along a 1,400 metre strike length of the anomaly have now been completed, or are in progress, on six section lines at the Heruga discovery.  Significant copper, gold and molybdenum mineralization has been intersected in drill holes on five adjacent sections, representing 1,100 metres of strike length. Four drills are currently drilling on the Heruga Deposit, including a recently-collared hole (EJD0019), 200 metres south of the known mineralization.  Two additional holes (EJD0016and EJD0018) have also been completed on the Castle Rock IP anomaly located to the southeast of the Heruga Deposit.

Discussion and Highlights of Recent Drilling

The discovery of the Heruga Deposit marks a new style of molybdenum-rich mineralization not previously encountered on the Oyu Tolgoi trend.  While no age dating has been done yet on this mineralization, the deposit is hosted by late-Devonian basaltic volcanics and quartz monzodiorite similar to the host rocks of the Oyu Tolgoi deposits. The structural corridor that bounds the Heruga Deposit also is flanked by Devonian and Carboniferous volcanic rocks similar to the Oyu Tolgoi structural corridor. The area between Southwest Oyu and Heruga is cut by two late, east-northeast trending faults that have likely down-dropped the intervening ground.

Drilling to date has delineated a 1,100 metre long, coherent zone of gold-rich copper mineralization, as defined in holes EJD0015, EJD0013 and EJD0017A, lying beneath a molybdenum-rich shell. For example, hole EJD0017A, a re-drill of hole EJD0017 from 578 metres, was collared 200 metres east of EJD0009.  The hole, which is currently drilling at a down-hole depth of more than 1,300 metres in visually strong chalcopyrite with minor bornite mineralization, has intersected 334 metres, starting at 740 metres down-hole, grading 0.32 g/t gold, 0.63% copper and 269 ppm molybdenum.  At a down-hole depth of 1,074 metres, the hole has intersected 36 metres of 0.81g/t gold, 0.72% copper and 54 ppm molybdenum with assays from lower sections pending. This intersection may represent the start of a gold-rich zone lying below the molybdenum shell.

The Heruga Deposit has been cut longitudinally by a north-south fault, the Bor Tolgoi Fault, with an apparent 500 metres, west side down-sense of movement.  The most northerly intersection into the deposit in hole EJD0007 is clearly on the west side of this fault. Three hundred metres to the south of hole EJD0007, hole EJD0011 intersected the fault at a depth of 550 metres and, starting at 1,008 metres, intersected molybdenum-rich mineralization grading 0.31 g/t gold, 0.45% copper and 212 ppm molybdenum, also on the west side of the fault.  Holes EJD0015 and 0015A, collared 200 metres to the east of hole EJD001, are clearly on the east side of the fault and intersected strong gold mineralization underlying the molybdenum-rich zone. The 298 metre intersection in hole EJD0014, a further 300 metres south of hole EJD0015, and the 166 metre intersection in hole EJD0012 were also cut off at the bottom by the Bor Tolgoi Fault.   

The true thickness of the individual intersections is not clearly understood at this early stage in the exploration as the full geometry and orientation of the deposit is not fully defined.  On sections where two or more drill holes have intersected mineralization, such as EJD0009 and EJD0017A, the apparent thickness or horizontal width of the zone extending from a known geological fault boundary to 100 metres east of the eastern most hole, EJD0017A, is at least 400 metres, with a vertical extent of up to 500 metres. On sections, where only one hole has intersected the zone, such as holes EJD0007 and EJD0014, and no holes have been drilled on the eastern side, it is not yet possible to determine the true thicknesses and depths of the intersections, or the orientation of the mineralization.

The potential for the continuation of the gold-rich mineralization north, to EJD0007 on the east side of the Bor Tolgoi Fault, is a clear exploration target that will be tested by future drilling; as will the entire deposit to the east of the existing holes. The potential southern strike extent is now being tested by new hole, EJD0019, collared 200 metres south of EJD0017A.

The Oyu Tolgoi structural trend as currently defined now has a total strike length in excess of 20 kilometres, encompassing Oyu Tolgoi in the centre and extensions onto the joint Entrée/Ivanhoe agreement area to both the south and north. From the Heruga Deposit in the south, the trend now extends through the Oyu Tolgoi deposits to the lower grade Ulaan Khud or Airport North Zone, located approximately 10 kilometres north-northeast of the Hugo Dummett Deposit.
