Significant High-Grade Copper-Gold Intercepts in Resource Definition Drilling on Ivanhoe Australia's Starra 276 Deposit

Resource Update for Starra 276 on Track for Completion in First Quarter of 2012

MELBOURNE, AUSTRALIA--(Marketwire - Jan. 18, 2012) - Robert Friedland, Chairman, and Peter Reeve, Chief Executive Officer of Ivanhoe Australia Limited (TSX:IVA)(ASX:IVA), are pleased to announce the completion of the Starra 276 resource definition program, which has continued to record significant high-grade copper-gold intercepts on the company's Cloncurry tenements in northwestern Queensland.

"Results from the three most recent holes in Starra 276 continue to provide a strong degree of confidence in the resource model, ensuring a robust and reliable contribution of Starra 276 to the Osborne Copper Gold Project mill feed," said Mr Reeve.

During 2011, Ivanhoe Australia completed a 31-hole resource definition program. Assay results for 27 of these holes have been received; the most recent include high-grade copper-gold intercepts from the following three holes:

STQ1078 - 20 m @ 2.56% copper and 0.75 g/t gold from 310 metres.
including 15 m @ 3.02% copper and 0.98 g/t gold from 315 metres;
and 19 m @ 1.32% copper and 0.58 g/t gold from 373 metres;
including 1.6 m @ 9.45% copper and 1.62 g/t gold from 380 metres.
STQ1073 - 18 m @ 2.01% copper and 0.91 g/t gold from 318 metres;
including 13 m @ 2.60% copper and 1.00 g/t gold from 318 metres;
including 2 m @ 4.50% copper and 3.51 g/t gold from 329 metres;
and 2 m @ 2.26% copper and 0.06 g/t gold from 384 metres.
STQ1074 - 16 m @ 0.88% copper and 0.82 g/t gold from 404 metres;
including 2 m @ 3.30% copper and 0.95 g/t gold from 404 metres;
and 17 m @ 1.32% copper and 1.31 g/t gold from 444 metres;
including 2 m @ 2.26% copper and 1.17 g/t gold from 446 metres;
including 9.7 m @ 1.63% copper and1.85 g/t gold from 451.3 metres;

A complete set of intercepts is presented in Table 1, below. Refer to Figure 2 for the location of these holes and potential resource extension zones.

Mr. Reeve said that the updated Mineral Resource at the Starra 276 ironstone-hosted mineral system is on track for completion in the first quarter of 2012.

"Significant results from drilling undertaken outside the current resource definition block model highlight the potential to increase the Mineral Resource.

"These results are an early and exciting taste of what Ivanhoe Australia's strategy of focusing exploration on the Starra Line might provide in the way of additional copper-gold ore sources for the Osborne mill complex."

Resource Extension Potential

Potential resource extensions of the Starra 276 deposit have been identified from down hole electromagnetic (geophysical) surveys. The Q1 2012 drilling program of the two conductive bodies has commenced with hole pST276A, refer to Figure 1 for the location of this hole.

Quality Control and Qualified Person Statement

Quality control and assurance programs are implemented in line with the standards of National Instrument 43-101. The exploration program on Starra 276 is overseen by Geoff Phillips, the Manager Resource Geology of the Company and a Qualified Person as defined under National Instrument 43-101. Mr Phillips has overseen the Resource Definition program at Starra 276 and supervised the scientific and technical information contained in this news release.

QAQC Statement

Ivanhoe Australia's core sampling within mineralised zones is generally taken on continuous one-metre intervals down each drill hole, or on smaller lengths over narrow geological units, for large disseminated or weakly mineralised zones sample lengths may increase to a maximum of two metres. 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. Core is cut with a rock saw flushed continually with fresh water and one-half of NQ/HQ core or one-quarter of PQ core is taken for analysis. Reverse circulation (RC) samples are taken on continuous one- or two-metre intervals down each drill hole and collected from a rig-based cone splitter.

Sample dispatches include Certified Reference Materials (CRMs), Field Blanks, Field Duplicates, Crushed Duplicates, and Pulp Duplicates. The CRMs, Field Duplicates, and Field Blanks are randomly inserted during sampling, whereas the Crushed and Pulp Duplicates are inserted at the laboratory. CRMs are certified for gold, copper, molybdenum, and/or rhenium.

Samples are placed in plastic bags, sealed, and collected in large, labelled shipping bags that are secured and sealed with numbered tamper-proof security tags. Samples are shipped to ALS Laboratory Group's Mineral Division at Mount Isa for preparation. Gold, copper, molybdenum, and rhenium assays, and multi-element geochemical analyses are conducted at ALS Mount Isa, Townsville, and Brisbane laboratories. ALS operates in accordance with ISO/IEC 17025.

Reference material assay values are tabulated and compared to those from established Round Robin programs. Values outside of pre-set tolerance limits are rejected and samples subject to re-assay. A reference material assay fails when the value is beyond the 3SD limit and any two consecutive assays fail when the values are beyond the 2SD limit on the same side of the mean. A Field Blank fails if the assay is over a pre-set limit.

Ivanhoe Australia also regularly performs check assays at an independent third party laboratory, conducts onsite internal QAQC reviews, and laboratory reviews to ensure procedural compliance for maintaining industry standard best practices.
