News Release

HONG KONG – Robert Friedland, Executive Chairman of Ivanhoe Mines Ltd. (TSX: IVN), and Lars-Eric Johansson, Chief Executive Officer, announced the completion today of the investment by China-based Zijin Mining Group Co., Ltd. in Ivanhoe’s Kamoa Copper Project in the Democratic Republic of Congo.

Zijin, through a subsidiary company, has acquired a 49.5% interest in Kamoa Holding Limited for a total of US$412 million in a series of payments. These funds will be paid into Ivanhoe’s corporate treasury and will be utilized by the company for general corporate purposes.

Ivanhoe received an initial US$206 million from Zijin today; the remaining US$206 million will be received in five equal installments, payable every 3.5 months from today. The Zijin investment, combined with Ivanhoe’s cash, cash equivalents and short-term deposits, will make a total of approximately US$530 million (C$716 million), exclusive of current liabilities, available to advance Ivanhoe’s tier one projects in South Africa and the Democratic Republic of Congo.

Of this total, approximately US$61 million (C$82 million) is reserved for use at Ivanhoe’s Platreef Project in South Africa.

The total cash, cash equivalents, short-term deposits and receivables from Zijin, exclusive of current liabilities, represent approximately C$0.92 per issued and outstanding common share of Ivanhoe Mines.

Kamoa Holding is an Ivanhoe Mines subsidiary that presently holds the company’s interest in the Kamoa Project. Ivanhoe also has sold 1% of its share interest in Kamoa Holding to Crystal River Global Limited, which is operated from Hong Kong.

“It is satisfying to complete this transaction with Zijin amid these interesting market conditions,” said Mr. Friedland.

“Our partnership with Zijin will allow us to develop Kamoa into a major, tier one copper mine at a time when conditions in commodity markets are compelling virtually all others to run in the opposite direction. When the consistent, downward trend in head grades at the world’s major copper mines is combined with the current drastic curtailment in exploration and development spending, as well as cutbacks in sustaining capital, we are highly confident we will see a significant copper-supply deficit and a sharp rise in copper prices as this decade draws to a close – at approximately the same time as we expect Kamoa to begin decades of commercial production. The old adage again is proving to be very true: The best cure for low prices is low prices.”

Mr. Johansson said Ivanhoe “is confident that Kamoa will become one of the world’s truly great copper mines and we are proud to partner together with Zijin to build and operate it. Together with Zijin, we will work hard to ensure that Kamoa

With Indicated Mineral Resources of 739 million tonnes grading 2.67% copper, containing 43.5 billion pounds of copper, and Inferred Mineral Resources of 227 million tonnes grading 1.96% copper, containing 9.8 billion pounds of copper (at a 1% copper cut off), Kamoa is independently regarded as Africa’s largest, high-grade copper discovery¹ and the world’s biggest, undeveloped high-grade copper discovery². In March this year, members of the Ivanhoe Mines exploration team received the prestigious Thayer Lindsley Award from the Prospectors & Developers Association of Canada for the Kamoa copper discovery, recognized as 2014’s top international mineral discovery.

The 2013 Kamoa preliminary economic assessment (PEA) presented a two-phased approach to development of the Kamoa Project (https://www.youtube.com/watch?v=Tb3v8OBHhs0). The first phase of mining will target high-grade copper mineralization from shallow, underground resources to produce approximately 100,000 tonnes of contained copper per year in a high-value concentrate. The Kamoa PEA estimated that the pre-production capital required for Kamoa’s first phase of development would be approximately US$1.4 billion. The proposed second phase will entail a major expansion of the mine and mill, and construction of a smelter to produce approximately 300,000 tonnes of blister copper each year. The Kamoa pre-feasibility study is progressing and the completed report is expected to be finalized in early 2016.

Key terms of Zijin’s investment

• Ivanhoe received US$206 million of the US$412 million total purchase today. The remaining US$206 million will be received in five equal installments that Zijin is scheduled to pay to Ivanhoe every 3.5 months from closing.
• Ivanhoe has agreed to sell 1% of its share interest in Kamoa Holding to Crystal River for US$8.32 million – which Crystal River will pay through a non-interest-bearing, 10-year promissory note. Crystal River is a private company controlled by So Hon Chun.
• Upon the successful arrangement or procurement of project financing by Zijin on terms approved by shareholders holding in the aggregate no less than 80.01% of the total issued and outstanding shares of Kamoa Holding, Zijin will have the right to acquire Crystal River’s 1% share interest (the 1% Option) in Kamoa Holding.
• The relationship between Ivanhoe Mines, Zijin and Crystal River will be governed by a Shareholder, Governance and Option Agreement (SGOA). The SGOA provides, among other things, that all key decisions regarding the development and operation of the Kamoa Project will be made by Kamoa Holding’s Board of Directors.

Additional details of the transaction and the SGOA are contained in the news release issued by Ivanhoe Mines on May 26, 2015.
