Additional High-Grade Zinc and Copper Assay Results Returned From Drilling Program at the KIPUSHI Mine in D.R. Congo

First hole completed across Big Zinc zone from hangingwall drill drift on the 1,272-metre level

LUBUMBASHI, THE DEMOCRATIC REPUBLIC OF CONGO -- (Marketwired) -- 09/05/14 -- Robert Friedland, Executive Chairman of Ivanhoe Mines (TSX: IVN), and Lars-Eric Johansson, Chief Executive Officer, announced today that the second batch of assay results from the company's underground diamond-drilling program at the Kipushi copper-zinc-germanium-lead and precious-metals mine has returned more exceptionally high-grade zinc and copper drill intercepts.

The majority of the new drill results are from the Serie Recurrente (Recurring Series) zone, which continues to return high-grade copper and zinc-rich intercepts. Results (all estimated true widths) include:


--  KPU011: 16.1 metres grading 4.9% copper, 5.8% zinc and 23 grams per
    tonne (g/t) silver.

--  KPU013: 13.7 metres grading 9.9% copper, 12.1% zinc, 37 g/t silver and
    24 g/t germanium.

--  KPU014: 8.7 metres grading 5.7% copper, 22.5% zinc, 33 g/t silver and 28
    g/t germanium.

--  KPU015: 9.7 metres grading 9.0% copper, 0.5% zinc, and 30 g/t silver.

--  KPU020: 5.2 metres grading 21.0% copper, 2.3% zinc, 190 g/t silver and
    10 g/t germanium.

Drilling well underway on Kipushi's 1,272-metre level: Defining the Big Zinc zone's historical resources, never mined since the discovery in the late 1980s.

Ivanhoe has commenced drilling of the Big Zinc zone from the hangingwall drill drift on the 1,272-metre level, a significant development since drilling from this drift provides the geometry for near-true-width intercepts across the Big Zinc zone. The first hole from the 1,272-metre level, hole KPU040, has just been completed and represents the first of Ivanhoe's holes designed to allow estimation of the historical Big Zinc indicated resource - originally established through pre-1993 drilling by the previous owner - in line with current guidelines set by the Canadian Institute of Mining, Metallurgy and Petroleum.

Hole KPU040 was drilled at -65 degrees between two historical Gecamines holes and intersected massive sulphide mineralization over a downhole distance of approximately 90 metres. The observed mineralization in this hole confirmed the overall geometry of mineralization seen in the adjacent historical holes of a massive sulphide body approximately 70 to 80 metres thick on this section line.

The intersection consisted of massive sphalerite (zinc), chalcopyrite and bornite (copper) and pyrite of the Big Zinc zone. The second hole in the hangingwall drilling program targeting the Big Zinc zone is currently underway.

Ivanhoe cautions that the presence of observed mineralization is not presented to confirm historical assay results. It confirms only the presence of mineralization similar in style to that observed in historical holes drilled by state-owned mining company Gecamines. Assays are pending for a number of drill holes, including KPU040.

Mr. Friedland commented, "These latest assay results continue to highlight the remarkable grades and widths of mineralization present at Kipushi. The completion of the first of our planned drill holes across the Big Zinc zone from the hangingwall drill drift marks the successful attainment of another milestone in our goal of establishing an updated, compliant resource in the Big Zinc zone."

Ivanhoe now has completed 35 holes totalling approximately 7,350 metres of its planned 20,000-metre underground diamond drilling program. Safe drilling access to the important 1,272-metre level now is complete. Two diamond-drill rigs are active. The first is in the hangingwall drill drift on the 1,272-metre level targeting the Big Zinc zone. The second rig is expected to complete the drilling of five remaining holes in the Serie Recurrente zone in approximately two weeks, after which it will be relocated to the 1,272-metre level. Hole KPU040 represents the first of 24 holes and 5,680 metres of drilling planned for the Big Zinc hangingwall drilling program. An additional 12 drill holes also are planned to test for deep extensions to the Big Zinc zone, of which seven will be completed from the hangingwall drift and the remainder from various locations on the decline.

Key recent infrastructure upgrades at Kipushi.

Ivanhoe is continuing to make significant infrastructure upgrades on the surface and underground as part of its planned redevelopment of the Kipushi mine. Most fabrication work has been done on site utilizing the re-commissioned machine shop and boilermaker shop facilities.

Key recent upgrades include:


--  installation and commissioning of the new main ventilation fan at Shaft
    #4;

--  construction of a water dam and installation of a major pump station on
    the 1,112-metre level; and

--  winder upgrades at Shaft #5 to facilitate the installation of permanent
    pumping arrangements and shaft restoration.

The installation of the new main ventilation fan at Shaft #4 has significantly increased the airflow on the Cascades side of the mine, where the majority of expected future mining operations would be conducted. Good progress has been made in the rehabilitation of Shaft #5, its winders and associated infrastructure. Access to the 1,210-metre level on the Shaft #5 side of the mine is expected in Q1 2015 to enable re-equipping of the mine's settling and pumping facilities.

About Kipushi

The Kipushi Mine forms part of the Central African Copperbelt in the D.R. Congo's southern province of Katanga, approximately 30 kilometres southwest of the provincial capital of Lubumbashi and less than one kilometre from the international border with Zambia.

Following its start-up in 1924 as the Prince Leopold Mine, Kipushi produced a total of 6.6 million tonnes of zinc and 4.0 million tonnes of copper - from 60 million tonnes of material grading 11% zinc and approximately 7% copper - until political instability prompted the suspension of operations in 1993. The mine also produced 278 tonnes of germanium between 1956 and 1978.

In addition to the recorded production of copper, zinc, lead and germanium, historical mine-level plans for Kipushi also report the presence of precious metals, specifically silver and rhenium. There is no formal record of precious metal production on the property.

The lower levels of the mine flooded in early 2011 due to a lack of pumping maintenance over an extended period. Ivanhoe Mines (formerly Ivanplats) acquired a 68% interest in Kipushi in November 2011 and has assumed responsibility for ongoing redevelopment, dewatering and drilling. The state-owned mining company Gecamines holds the remaining 32% interest in Kipushi.

Kipushi's distinct copper- and zinc-rich zones

Previous mining at Kipushi was conducted from surface to approximately the 1,220-metre level; mineralization was projected to extend to 1,800 metres below surface, based on Gecamines drilling. Mining historically occurred primarily within three contiguous zones: the North and South zones of the approximately north-south-striking, approximately 70-degree west-dipping Kipushi fault; and the approximately east-west-striking, steeply north-dipping Serie Recurrente zone in the footwall of the fault. The Serie Recurrente zone derives its name from the geological formation with which it is associated, which is characterized by a series of alternating or recurring beds of dolomite and siltstone/shale.

High-grade copper was particularly well developed in the North and Serie Recurrente zones. Historically, Gecamines referred to a portion of the North zone as the Nord Riche (Northern Rich) area, which occurred at the structural junction of the Kipushi fault and the Serie Recurrente zone. The Nord Riche area has been incompletely explored below previous workings. Historical underground mine plans show that mineralization in the Nord Riche area was significantly thicker than in the Serie Recurrente area where Ivanhoe has been drilling.

High-grade zinc was common in the South zone, and also occurred as small but very high-grade bodies in the footwall of the fault in the upper levels of the mine. The Big Zinc represents a much larger and as yet unmined historical resource, also in the footwall of the fault, and is incompletely tested at depth. Accessible from existing underground workings, the Big Zinc, as defined historically, has a strike length of at least 100 metres, a down-plunge dimension of approximately 300 to 350 metres and a true thickness calculated at 40 to 80 metres.
