New drill hole at Oyu Tolgoi intercepts 938 metres
of near-continuous copper/gold mineralization
between Heruga Deposit and Southern Oyu deposits

Intercepts of up to 10 grams of gold/tonne near bottom of hole
in discovery area now known as Heruga North

ULAANBAATAR, MONGOLIA — Robert Friedland, Executive Chairman of Ivanhoe Mines Ltd., and Richard Gosse, Vice-President, Exploration, announced today that the company has intercepted almost one kilometre of near-continuous gold and copper mineralization in drill hole OTD1510 at Oyu Tolgoi, making it the longest exploration drill intercept of gold and copper mineralization recorded since Ivanhoe began drilling at the Oyu Tolgoi Project in 2001.

Hole OTD1510 intercepted 112 metres grading 1.36 grams of gold per tonne (g/t) and 0.34% copper, with a copper equivalent grade of 1.21% (CuEq), at a down-hole depth of between 2,286 and 2,398 metres. The intercept included 20 metres grading 3.78 g/t gold and 0.64% copper, with a CuEq grade of 3.06%, at a down-hole depth of between 2376 and 2396 metres, and six metres of 8.4 g/t gold and 0.66% copper, with a CuEq grade of 6.05%, at a down-hole depth of between 2388 and 2394 metres.

Individual two-metre samples near the bottom of hole OTD1510 returned gold assays of approximately 10 grams per tonne — among the highest gold grades ever drilled at Oyu Tolgoi.

Over the entire 938-metre intercept, OTD1510 averaged 0.42 g/t gold and 0.46% copper, with a CuEq grade of 0.76%, at a down-hole depth of between 1460 and 2398 metres (true depth below surface of between approximately 1200 and 1885 metres).

“To intercept almost one kilometre of copper and gold mineralization in a new drill hole is a remarkable development, considering that we already have drilled more than 1,650 holes totalling almost 900 kilometres at the project during the past 10 years,” Mr. Friedland said.

“Drill hole OTD1510 extends the Oyu Tolgoi mineralized system and demonstrates yet again the incredible potential to significantly add to the presently defined copper and gold resources. While Oyu Tolgoi already is one of the world’s largest deposits of gold and copper, hole OTD1510 is consistent with our long-held view that the Oyu Tolgoi mineralized system contains significantly more gold and copper than we have delineated to date under NI 43-101 standards. We are particularly pleased to see this outstanding intersection in hole OTD1510, right where the advanced technology, induced-polarization section indicated it would be found.”

Maps and sections of the Oyu Tolgoi discovery are attached at the back of this release.

The area, previously known as the New Discovery Zone, now has been renamed Heruga North. The OTD1510 intercept indicates that Heruga North is part of a 2.5-kilometre, gold-rich mineralized extension of the Heruga Deposit, stretching north from the southern border of the Oyu Tolgoi mining licence to the Southern Oyu deposits.

Based on interpreted geology and a large, coincident, gradient-array induced polarization (IP) chargeability anomaly identified by proprietary, deep-exploration technology, Hole OTD1510 was targeted on a critical, 600-metre gap in the known mineralization between the northern, fault-controlled limit of the Heruga Deposit and the former New Discovery Zone.

Heruga North discovery confirms ongoing potential to expand Oyu Tolgoi system

The 938-metre Heruga North intercept in Hole OTD1510 covers a horizontal distance of 643 metres and a vertical distance of 681 metres. The hole was stopped after it entered the West Bat Fault, which appears to form the western boundary of the high-grade mineralization. Ivanhoe has begun drilling a daughter hole — OTD1510B — to better delineate the extent of the gold-rich mineralization encountered in OTD1510.

Highlighted Heruga North drill holes previously reported by Ivanhoe include:

•

OTD1487A — 2.13 g/t gold and 0.82% copper (CuEq grade 2.24%) over 78 metres from 2258 and 2336 metres.

•

OTD1487A — 0.85 g/t gold and 0.54% copper (CuEq grade 1.12%) over 358 metres from 1978 and 2336 metres.

•

OTD1487 — 0.10 g/t gold and 1.65% copper (CuEq grade 1.73%) over 16 metres from 1978 and 1994 metres.

•

OTD1487 — 0.85 g/t gold and 0.89% copper (CuEq grade 1.47%) over 25.7 metres from 2028 and 2053.7 metres.

Mr. Friedland said that the discovery of additional, multi-kilometre-long zones of gold-rich porphyry mineralization, like Heruga North, allows for considerable flexibility in future development phases at Oyu Tolgoi. “It’s possible that Heruga and Heruga North eventually could be developed together as one of the world’s largest underground gold mines.”

Construction of Oyu Tolgoi is on schedule to begin initial production in late 2012.

Heruga North extends the Heruga Deposit

Ivanhoe’s deep diamond drilling between the Heruga Deposit and the Southwest Oyu deposits first identified the zone, now named Heruga North, in December 2008. Since the initial discovery, Ivanhoe has completed approximately 43,500 metres of wide-spaced diamond drilling into the Heruga North zone. The name Heruga means “supreme happiness.”

Geological modelling indicates that Heruga North is the northern continuation of the Heruga Deposit, with a horizontal displacement of more than 500 metres along a fault between the two zones. The top of Heruga North is approximately 1,100 metres below surface and slopes gradually downward as it extends to the north. The Solongo Fault forms the current northern limit of mineralization. Although the overall limits of the system have yet to be defined, an approximate 2.5-kilometre, northeast-trending corridor from the Heruga Deposit in the south to the Solongo Fault in the north is potentially mineralized over a height of at least 700 metres and width of up to 700 metres.

There has been insufficient drilling to define a mineral resource at Heruga North. However, given the current dimensions of the copper-gold-molybdenum mineralized zone defined to date and drill results, Ivanhoe believes that the Heruga North exploration target could have similar tonnage and grade to the adjoining Heruga Deposit. As of March 2010, the Heruga Deposit had an estimated inferred resource of 970 million tonnes grading 0.48% copper, 0.48 g/t gold and 140 ppm molybdenum, for a copper equivalent grade of 0.86%, using a 0.60% copper equivalent cut-off grade. Based on the March 2010 estimate, the Heruga Deposit contains an estimated 10.2 billion pounds of copper and 15 million ounces of gold.

See Ivanhoe’s March 2010 AIF on www.ivanhoemines.com or www.sedar.com for details of the Heruga resource estimate. Mineral resources are not mineral reserves until they have demonstrated economic viability based on a feasibility study or pre-feasibility study.

Heruga North a major new gold-rich mineralized zone

Ivanhoe has two diamond rigs drilling additional holes from surface into Heruga North to advance the discovery toward an initial inferred resource estimate. The estimated size of Heruga North is based on wide-spaced drilling that Ivanhoe believes has not fully delineated the higher-grade, gold-rich zone.

Mr. Gosse said that some of the deeper drill intercepts in Heruga North have some of the highest gold grades (up to 10 g/t gold) and gold-to-copper ratios (higher than 10-to-1 g/t gold to % copper) identified to date at Oyu Tolgoi. The gold-rich zone in Heruga North is analogous to the gold-rich zone at the Heruga Deposit.

“Based on the high gold and copper grades, as well as the high gold-to-copper ratio encountered and the style and tenor of the porphyry mineralization, the significance of Heruga North compares favourably to the major deposits that currently comprise the Oyu Tolgoi Project,” Mr. Gosse said.

Quality Assurance and Quality Control

Dr. David Crane, R.P.Geo., Ivanhoe Mines’ Mongolia Exploration Manager, a member of the Australian Institute of Geoscientists and a qualified person as required by NI 43-101, supervised the preparation of the information in this news release.

The QA/QC program used at the Oyu Tolgoi Project was developed by Dr. Barry Smee, P.Geo., an independent quality control consultant, and adopted in April 2002. Oyu Tolgoi LLC’s sampling procedure comprises collection of core samples taken on continuous two-metre intervals down each drill hole, excluding dykes that extend more than 10 metres along the core length. Samples of one-half of NQ and HQ core, or one-quarter of PQ core, are taken for assaying. The core is marked with a continuous cutting line along the middle, parallel to the long axis for the purpose of preventing a sampling bias during splitting. Splitting is done with a rock saw flushed continually with fresh water. Samples are placed in cloth bags and sent to an on-site preparation facility operated by SGS Mongolia LLC. In-house, matrix-matched copper-gold-molybdenum standards, and blanks and duplicates are inserted at the sample preparation lab at the project site for quality-control monitoring of the assay data. All samples are assayed for gold, copper, molybdenum, arsenic and silver.

Upon receipt of assay results, values for Standard Reference Material samples and field blanks are tabulated and compared to those from an established round-robin program. Assay results that deviate from round-robin program results beyond pre-set tolerance limits are rejected and subject to re-assay. Oyu Tolgoi also performs check assays on a regular basis at the rate of one per batch of 20 samples.
