Ivanhoe to leverage its decades of exploration expertise in

discovering Tier-One sediment-hosted copper deposits in the

Western Foreland shelf

ALMATY, KAZAKHSTAN – Ivanhoe Mines (TSX: IVN; OTCQX: IVPAF) Executive Co-

Chairman Robert Friedland and President Marna Cloete announced today that an

Exploration Joint Venture has been formed to explore the Chu-Sarysu Copper Basin in

Kazakhstan, the world’s third-largest sediment-hosted copper district.

The Joint Venture, with UK-based private company Pallas Resources, covers a highly

prospective licence package of up to 16,000 km2, which spans an accumulated dataset

of Soviet-era exploration data. For comparison, the licence package is approximately

7.5 times the size of Ivanhoe’s Western Forelands Exploration Project.

Ivanhoe has committed to fund $18.7 million in exploration activities over an initial two

year period, with earn-in rights to further increase ownership up to 80% over time.

Exploration activities are underway, including the hiring of a dedicated exploration

team. An airborne geophysics contract is currently under tender and is expected to be

awarded imminently.

Ivanhoe Founder and Executive Co-Chairman Robert Friedland commented:

“You may be wondering why we are going to Kazakhstan? It is because Kazakhstan is a

major mining jurisdiction and host to the world’s third largest sedimentary copper

basin. The Ivanhoe Group has a long history in Kazakhstan …we love the country, we

love its people and we look forward to returning to this tremendous country to further

unlock the significant geological potential of the Chu-Sarysu Basin.

“We know how to find tier-one sedimentary copper deposits, and we know how to mine

them. The landmark development of the Kamoa-Kakula Copper Complex and the

2

expanding discoveries of the Western Forelands, in the Democratic Republic of Congo,

are testament to this. We will be building on our successes over the past 28 years here,

where we have discovered over 50 million tonnes of copper… and counting.

“Ivanhoe’s strategic partnership marks an exceptional opportunity to utilize our

exploration expertise in one of the world’s most prospective sedimentary copper

basins. With over 16,000 km² of license applications in the Chu-Sarysu Basin—the

largest land-holding position in the region—we are poised to become one of the most

significant global copper exploration stories.

“With a legacy of accomplishments in emerging mineral jurisdictions, including

Kazakhstan, Ivanhoe takes pride in applying its expertise to generate lasting value for

our shareholders and the communities in which we operate. Our commitment extends

beyond discovering vital copper resources, focusing on sustainable development and

creating long-lasting economic opportunities in Kazakhstan.

"This partnership marks an excellent addition to our growing copper exploration

portfolio to further accompany the rapidly advancing Western Forelands licenses

adjacent to Kamoa-Kakula. Western Forelands underpins the next stage of our

aggressive copper production growth story, and we expect to update the market on

these exciting exploration efforts in the Democratic Republic of Congo shortly."

Kazakhstan’s Chu-Sarysu Basin is the world’s third-largest sedimentary

copper basin, after the prolific Central African Copperbelt

The Chu-Sarysu is the world’s third-largest sediment-hosted copper basin, after the

Central African Copperbelt and European Kupferschiefer, hosting 27 million tonnes of

known copper.

It includes major deposits such as the 100-year-old Zhezkazgan complex, which

contains over 22 million tonnes of copper. The vast complex produces approximately

200,000 tonnes of copper per annum, along with significant silver by-products, from one

open pit mine and 6 underground mines.

The United States Geological Survey (USGS) estimates that there remains

approximately 25 million tonnes of undiscovered copper in the Chu-Sarysu Basin,

highlighting its untapped potential. In addition, the basin includes occurrences of lead,

zinc, silver, barium and strontium. Despite its significant prospectivity, greenfield

exploration has been largely neglected across the entire region for over 40 years.

The Joint Venture intends to leverage Ivanhoe Mines’ decades of exploration success in

discovering over 50 million tonnes of sediment-hosted copper deposits in the Western

Foreland shelf of the Democratic Republic of Congo, including the Kamoa, Kakula,

Makoko and Kitoko discoveries.

The world’s richest sediment-hosted copper districts, with the Chu-Sarysu basin

ranked as the third-largest worldwide.

Ivanhoe searches for the next major copper discovery over a 16,000-km2

licence package, 7.5 times the size of the Western Forelands

Ivanhoe has acquired an initial 20% equity interest in the joint venture licence package

and commits to $18.7 million in exploration expenditure over the next two years.

Licence applications were made in Q4 2024, totalling approximately 16,000 km2.

Ivanhoe’s joint venture partner, UK-based Pallas Resources, has accumulated and

digitized a large dataset of Soviet-era exploration data spanning the licence package.

Initial analysis of the digitized historic dataset has highlighted a number of potential

targets, which will be investigated further following the completion of an airborne

geophysics program later this year.

After the initial two-year period, Ivanhoe has the right to earn a majority interest by

spending up to $115 million, based on retaining the entire licence package, over the

subsequent four years. This additional exploration expenditure is at Ivanhoe’s

discretion on a licence-by-licence basis and it has the right to adjust the program

accordingly, subject to exploration success and prospectivity.

In the event of a major new copper discovery, Ivanhoe can earn up to an 80% equity

interest by funding and completing a pre-feasibility study.

operations. According to USGS, the Chu-Sarysu Basin, contains approximately

25 million tonnes of undiscovered sediment-hosted copper.

Kazakhstan is a low-cost, mining-friendly jurisdiction that is underexplored

Kazakhstan has a rich history in mining. The Central Asian country currently ranks as

the world’s largest uranium producer, the world’s second-largest chromite producer,

and is also a major producer of copper, zinc, iron ore and coal. Mining and quarrying

currently account for approximately 14% of the country’s gross domestic product (GDP)

and 17.5% of the country's exports, equivalent to approximately US$10.5 billion.

Kazakhstan is a highly cost-effective jurisdiction for mineral exploration and mining,

with a skilled workforce and a relatively low cost of operations, including labour and

power.

Despite its geological potential, exploration expenditure in Kazakhstan has notably

lagged behind other major mining jurisdictions. On average, approximately $100 million

has been spent per annum on exploration activities over the past 15 years, according to

data by S&P Global. However, the past 12 months have seen a notable increase in

exploration activity following a newly streamlined exploration licence registration

process, as well as the availability of Soviet-era geophysical data.

About Ivanhoe Mines

Ivanhoe Mines is a Canadian mining company focused on advancing its three principal

projects in Southern Africa; the expansion of the Kamoa-Kakula Copper Complex in the

DRC, the ramp-up of the ultra-high-grade Kipushi zinc-copper-germanium-silver mine,

also in the DRC; and, the phased development of the tier-one Platreef palladium-nickel-

platinum-rhodium-copper-gold project in South Africa.

Ivanhoe Mines is also exploring across its highly prospective, 60-100% owned

exploration licences in the Western Forelands, covering an area over 5 times larger than

the adjacent Kamoa-Kakula Copper Complex. Ivanhoe is exploring for new sedimentary

copper discoveries, as well as expanding and further defining its high-grade Makoko,

Kiala, and Kitoko copper discoveries as the company’s next major development

projects.
