David van Heerden are pleased to announce the company’s financial results for

the first quarter of 2025, as well as an operations and project development

update.

Ivanhoe Mines is a leading Canadian mining company developing and operating

its four principal mining and exploration projects in Southern Africa: expanding

production at the tier-one Kamoa-Kakula Copper Complex in the Democratic

Republic of the Congo (DRC); ramping up the ultra-high-grade Kipushi zinc-

copper-lead-germanium mine in the DRC; building the tier-one Platreef platinum,

palladium, rhodium, nickel, gold, and copper mine in South Africa; and advancing

exploration for new copper discoveries across the expansive exploration licenses

of Ivanhoe’s Western Forelands Exploration Project, which hosts the Makoko,

Kitoko, and Kiala copper discoveries near Kamoa-Kakula. All figures are in U.S.

dollars unless otherwise stated.

Founder and Co-Chairman Robert Friedland commented:

"Ivanhoe Mines is proud to report strong financial and operational

performance in the first quarter of 2025, reflecting the significant efforts of

our team and the broad shoulders of the world-class Kamoa-Kakula Copper

Complex.

“As we announced earlier this month, the initiatives to overcome power

challenges and secure sustainable short, medium, and long-term energy

sources for the growth of the world’s most important copper mine are

beginning to bear fruit.

“Kamoa-Kakula is set for record production in the shorter month of April,

achieving approximately 50,000 tonnes of copper in concentrate, equivalent

to an annualized rate of over 600,000 tonnes – a remarkable achievement.

This will provide the basis from which to continue our growth in 2026,

including our optimization projects such as Project 95, even before the

Phase 4 expansion.

"The start-up of Africa’s largest and greenest direct-to-blister is just a few

weeks away, which transforms Kamoa-Kakula into a fully integrated, low-

cost, multi-generational supermajor copper complex. First production of

99+% pure copper anodes is expected in July. This milestone will lower

transportation costs by more than 50% per unit of contained copper while

enabling us to sell by-product sulphuric acid locally to meet rising demand

in the Democratic Republic of the Congo’s copper industry.

"Exploration continues to play a vital role in our future growth. On our

Western Forelands licenses, we are making significant progress and will

release an interim Mineral Resource update by mid-May. This update will

highlight the immense potential of this highly prospective region adjacent to

Kamoa-Kakula.

"We have also recently expanded our exploration efforts into Zambia – a

country with tremendous geological prospectivity outside of the known

Copperbelt region. The government of Zambia is also a critical partner in

addressing long-term energy in the Southern African region.

“Finally, we praise the leadership of the governments of the United States

and Qatar for bringing together the governments of the DRC and Rwanda to

agree on principles of peace and prosperity, opening the way for increased

investment and the responsible development of DRC’s huge critical

minerals endowment that will be required to meet the rising global demand

for these essential metals.”

FINANCIAL HIGHLIGHTS

• Ivanhoe Mines recorded a profit of $122 million during Q1 2025, equivalent to a

basic profit of $0.10 per share, up from $88 million in Q4 2024. Profit included

Ivanhoe Mines’ share of profit and finance income from the Kamoa-Kakula

joint venture of $142.0 million, up from $127.3 million in Q4 2024.

• Ivanhoe Mines’ Q1 2025 adjusted EBITDA was a record $226 million, up from

$136 million in Q4 2024, which includes an attributable share of EBITDA from

Kamoa-Kakula of $231 million.

• Kamoa-Kakula recognized record revenue of $973 million, operating profit of

$471 million, and EBITDA of $585 million for Q1 2025, equivalent to a margin of

60%.

• Kamoa-Kakula’s first quarter record EBITDA of $585 million, compares with

$431 million in Q4 2024 and benefits in part from a positive remeasurement of

contract receivables of $51 million due to a rise in the copper price during the

quarter.

• Kamoa-Kakula sold 109,963 tonnes of copper (net of payability) during the first

quarter at an average realized copper price of $4.19/lb., compared with 112,881

tonnes in Q4 2024 at an average realized copper price of $4.08/lb. Sales

continued to lag production due to a build-up of inventory for the

commissioning of the smelter next month. At the end of the first quarter, there

were approximately 48,000 tonnes of unsold copper in inventory, up from

approximately 30,000 tonnes at the end of 2024.

• Kamoa-Kakula’s cost of sales per pound (lb.) of payable copper sold was

$1.87/lb. for the first quarter compared with $1.94/lb. in Q4 2024. Cash cost

(C1) per pound of payable copper produced in the quarter averaged $1.69/lb.,

compared with $1.75/lb. in Q4 2024, a reduction was achieved despite an

increase in energy costs resulting from backup generator usage.

• Kamoa-Kakula maintains its 2025 cash cost (C1) guidance of $1.65/lb. to

$1.85/lb. of payable copper produced, with first quarter cash cost at the lower

end of the range.

• Kamoa Copper signed offtake agreements with CITIC Metal (HK) Limited and

Gold Mountains International Mining Company Limited, a subsidiary of Zijin

Mining, for a combined 80% of the smelter’s anode production. CITIC Metal

and Gold Mountains also provided an advance payment facility of $250 million

each, totaling $500 million, the full amount of which was received in January

2025.

• Since entering Phase 1 commercial production on July 1, 2021, the Kamoa-

Kakula joint venture has generated over $6.1 billion of EBITDA and $5.2 billion

of operating cash flow, excluding working capital movements, which has

largely been re-invested in the now-complete Phase 2 and 3 expansions and

the direct-to-blister copper smelter, as well as optimization initiatives.

• Kipushi sold 30,108 tonnes of zinc (net of standard 85% payability for zinc

concentrate) during the quarter, which was up from the 16,999 tonnes of zinc

sold in Q4 2024 and still affected by ramp-up, recognizing revenue of $77

million and quarterly segmented EBITDA of $11 million. Kipushi’s cost of sales

per pound (lb.) of payable zinc sold was $1.23/lb. and cash cost (C1) per

pound of payable zinc sold totaled $0.93/lb.

• Ivanhoe Mines maintains Kipushi’s 2025 cash cost (C1) guidance of $0.90/lb.

to $1.00/lb. of payable zinc.

• On January 24, 2025, Ivanhoe Mines closed the inaugural offering of an

aggregate principal amount of $750 million senior unsecured notes due 2030,

bearing a coupon rate of 7⅞%. Ivanhoe also entered into a $120 million

revolving credit facility agreement, which remains undrawn.

• Ivanhoe Mines’ cash and cash equivalents on hand as at March 31, 2025, was

$717 million.

OPERATIONAL HIGHLIGHTS

• Kamoa-Kakula produced a near-record 133,120 tonnes of copper during the

first quarter. This compares with the quarterly record of 133,819 tonnes of

copper produced in Q4 2024 and 86,117 tonnes of copper in Q1 2024

• Imported hydroelectric power increased by 20 megawatts (MW) to 70 MW in

mid-March. Imported hydropower further increased to 100 MW after quarter

end. Further increases in grid power are expected during the second half of

2025 as the smelter ramps up.

• Copper production rate on an annualized basis increased to an average of

614,000 tonnes of copper since March 18, 2025, with daily records reaching as

high as 700,000 tonnes of copper annualized. Kamoa-Kakula is set to produce

a monthly record of approximately 50,000 tonnes of copper in April, a 30-day

month.

• Kamoa-Kakula’s Phase 1, 2, and 3 concentrators achieved a combined milling

record of approximately 3.7 million tonnes of ore during the first quarter, at an

average record recovery rate of 87.4%. The outperformance was underpinned

by the Phase 3 concentrator averaging throughput 20% above its design

capacity, equivalent to an annualized milling rate of 6 million tonnes per

annum.

• The Phase 1 and 2 concentrators milled 2.2 million tonnes of ore during Q1

2025 at an average grade of 5.01%, despite shutdowns for plant maintenance

in March. The Phase 3 concentrator milled 1.5 million tonnes of ore at an

average grade of 2.76%.

• Kamoa-Kakula’s 2025 production guidance is maintained at 520,000 to 580,000

tonnes of copper in concentrate. Annualized copper production at Kamoa-

Kakula is targeting approximately 600,000 tonnes of copper in concentrate

from 2026, following the completion of power initiatives currently underway,

as well as the optimization projects for improved Phase 1 and 2 recoveries

(“Project 95”) and increased Phase 3 throughput.

• Construction of Kamoa-Kakula's 500,000-tonne-per-annum on-site, direct-to-

blister copper smelter, the largest in Africa, is now complete with the smelter

undergoing commissioning. Start-up of the smelter is expected to commence

in May, with first copper anode production expected in July. Offtake

agreements with local buyers for the by-product, high-strength sulphuric acid

are well advanced.

• The “Project 95” initiative on Kamoa-Kakula’s Phase 1 and 2 concentrators is

advancing on schedule for completion in Q1 2026. The increase in

concentrator recoveries to 95% is expected to increase annualized copper

6

production by up to 30,000 tonnes, with an industry-leading capital intensity of

$6,000 per tonne of copper.

• Kamoa-Kakula’s 2025 Integrated Development Plan, covering all the planned

growth initiatives of the copper complex, is advancing well for completion in

mid-2025.

• In Q1 2025, the Kipushi concentrator milled a record 151,403 tonnes of ore at a

record average grade of 32.5% zinc, producing a record 42,736 tonnes of zinc

in concentrate at a contained grade of over 53% zinc. The ramp-up to steady

state of the ultra-high-grade Kipushi zinc mine is progressing well into the

second quarter.

• The Kipushi debottlenecking program is 66% complete and advancing on

schedule for completion late in the third quarter. The debottlenecking program

is targeting a 20% increase in the Kipushi concentrator’s processing capacity,

up to 960,000 tonnes of ore per annum.

• Kipushi’s 2025 production guidance is maintained at 180,000 to 240,000

tonnes of zinc in concentrate. Kipushi is targeting a production rate of over

250,000 tonnes of zinc in concentrate for 2026, following the completion of

ramp-up and debottlenecking activities.

• On February 18, 2025, Ivanhoe Mines announced two independent studies on

the Phase 2 and Phase 3 expansion of the Platreef platinum-palladium-

rhodium-nickel-gold-copper mine, outlining plans for Platreef to become one

of the world’s largest and lowest-cost producers.

• Platreef’s first production from the Phase 1 concentrator is expected in Q4

2025. The Phase 2 expansion is expected from Q4 2027, increasing production

to over 450 koz of platinum, palladium, rhodium, and gold per annum, as well

as significant nickel and copper by-products.

• Platreef’s Phase 3 expansion is expected to produce over 1.0 million ounces

of platinum, palladium, rhodium, and gold per annum, plus approx. 25,000

tonnes of nickel and 15,000 tonnes of copper.

• Equipping of Shaft #3 progressed well during the reporting period. Installation

of the rock winder commenced, with the mechanical and electrical work

advancing well. Shaft #3 is expected to be ‘ready to hoist’ from Q1 2026 with a

capacity of approximately 4 million tonnes per annum.

• Underground development at Platreef’s 850-metre level is imminently

expected to reach the Flatreef orebody. Further development in ore will be

stockpiled on surface and processed in the Phase 1 concentrator from Q4

2025.

• Ivanhoe continues exploration across its Western Forelands licences,

adjacent to Kamoa-Kakula, with 5 rigs drilling during the wet season. A

Mineral Resource update is expected to be released within the coming weeks

that will include all drilling completed since the maiden resource in December

2023 up to the end of March 2025. Drilling from the remainder of the 2025

program will be included in a subsequent Mineral Resource update next year.

• Ivanhoe Mines notes the Declaration of Principles jointly signed on April 25,

2025, by the governments of the Democratic Republic of the Congo and the

Republic of Rwanda, and witnessed by the government of the United States, to

support a pathway to peace, stability, and integrated economic development

in the eastern DRC, as well as the resumption of normal bilateral relations.

• On February 12, 2025, Ivanhoe Mines announced the forming of a joint venture

with a UK private company to commence exploration activities for sediment-

hosted copper discoveries in the Chu-Sarysu Basin, Central Kazakhstan. The

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

basin. The licence package currently under application is over 18,000 km2 and

is set to be the largest in the Chu-Sarysu Basin.

• On April 2, 2024, the Zambian government granted Ivanhoe Mines 7,757 km2 in

new exploration licences in North-Western Province, which are over three

times larger in area than Ivanhoe’s Western Forelands Exploration Project.

Exploration activities are expected to commence in this quarter after the wet

season ends.

Construction of Africa’s largest and greenest smelter project at Kamoa-

Kakula is now complete. Commissioning of the smelter is nearing

completion, with the first production of 99.7% copper anodes expected in

July.
