MOKOPANE, SOUTH AFRICA – Ivanhoe Mines (TSX: IVN) (OTCQX: IVPAF)

Executive Co-Chair Robert Friedland and President and Chief Executive Officer

Marna Cloete announced today that following the official opening and first

production of concentrate from the Platreef Mine, in Limpopo Province, South

Africa on November 18, 2025, the development of the Platreef mine continues to

rapidly advance as precious and base metals reach new highs.

Ivanhoe Mines’ Founder and Executive Co-Chairman, Robert Friedland,

commented:

“The world is waking up to a new metals super-cycle, where precious and base

metals are no longer optional, they are essential. Prices are rising because

scarcity is real and demand is relentless... This comes at a time when platinum,

palladium, rhodium, copper and nickel are identified by countries all around the

globe as strategic minerals.

“Into this moment steps the Platreef Mine, which has a once-in-a-generation

orebody… a discovery so vast that it will be producing precious metals for

generations to come, with 59 million ounces in indicated category and 94 million

ounces in inferred category… plus significant nickel and copper. The Platreef

Mine is not a typical South African precious metals mine scratching at narrow,

one-metre-thick seams... The Platreef system is a geological wonder. The flat-

lying orebody is approximately twenty-five times thicker than our industry

incumbents, averaging 26 meters of continuous mineralization…. thickness

means scale, which means mechanization, and mechanization means lower costs

and safer operations.

“Under our current thinking, while taking into account current record metals

prices, we are initiating discussions to dramatically bring forward the date for the

third phase of expansion. Watch this space...”

The Platreef Mine’s Phase 1 concentrator produced the first batch of platinum-

palladium-nickel-rhodium-gold-copper concentrate on November 18, 2025, during

the official opening ceremony. Since then, the concentrator continues to ramp up

in line with expectations. As previously guided, lower-grade development ore will

continue to be fed into the concentrator during the initial ramp-up stages until

Shaft #3 is ready to hoist in early Q2 2026, at which point feed will be increasingly

replaced by production ore. From early Q2 2026, the concentrator is expected to

3

steadily ramp-up, consistently achieving 80% of nameplate capacity by mid-year.

The 2026 production guidance will be provided at a later date, as the concentrator

ramp-up is more advanced.

Since late Q4 2025, underground development is also advancing on the 750-metre

level, as well as on the 850-metre level, where the Flatreef orebody was first

intersected in May 2025. Blasting of the first long-hole stoping blocks (production

mining) on the Platreef Mine’s 850-metre level is expected imminently. Ore tonnes

from the long-hole stopes will only be hoisted to surface in early Q2 2026 once

Shaft #3 is ready to hoist.

The completion of Shaft #3 is on track and is expected to be ready-to-hoist from

April 2026. Barrel equipping of the shaft and construction of the underground

loading box were both recently completed. The remaining workstreams of

installing the permanent headframe, and completing the installation of the

underground conveyors and loading infrastructure, are on track to be completed

by the end of the first quarter.

headframe (centre of picture) is the temporary headframe that was

originally erected for the sinking and equipping of Shaft #3. This headframe

will be replaced by the permanent headframe (right of picture) from late

January 2026. Once operational, Shaft #3 will increase total available

hoisting capacity from 0.8 Mtpa to approximately 5.0 Mtpa.

4

The completion of Shaft #3 will increase the Platreef Mine’s available hoisting

capacity by approximately five times to 5.0 million tonnes per annum (Mtpa). The

new shaft will enable greater flexibility of hoisting to surface both ore and waste

from the mine. Therefore, waste generated from the widening of Shaft #2, which is

expected to commence in April 2026, as well as waste development required in

preparation for the start of the Phase 2 expansion in Q4 2027, can be hoisted

concurrently with ore for the Phase 1 concentrator. This was not possible with

Shaft #1 alone.

In addition, the first sale of concentrate from the Phase 1 concentrator to

Northam Platinum Ltd, of Johannesburg, South Africa, took place in late Q4 2025.

Bulk transport trucks arriving at the Platreef Mine for the first sale of

concentrate. Revenue from the sale of the concentrate is provisionally

recognized as the trucks leave the mine gate.

Project development on Phase 2 expansion is already underway,

targeting completion in Q4 2027, to increase production to

approximately 450,000 ounces of platinum, palladium, rhodium and

gold

The Ivanplats’ project team has commenced work on Phase 2 development, with

the concentrator expansion targeted for completion in Q4 2027. DRA Global of

Perth, Australia, was recently appointed as the engineering, procurement and

construction management (EPCM) contractor for the Phase 2 underground

infrastructure and the 3.3-million-tonne-per-annum Phase 2 concentrator. DRA

5

Global was the EPCM contractor that delivered the Phase 1 concentrator on

schedule in June 2024. Earthworks on the Phase 2 concentrator site, located

adjacent to the Phase 1 concentrator, are scheduled to commence in the coming

weeks.

In addition, Shaft #2’s concrete headgear is now complete, and the expansion of

the shaft from an initial diameter of 3.1 metres to a diameter of 10 metres, will

commence in early Q2 2026, once Shaft #3 is ready to hoist. The appointment of

the contractor that will be widening the shaft, called slyping and lining, was

placed in late Q4 2025. Raise boring of Shaft #2 to the initial diameter of 3.1-

metres was completed in Q4 2024.

Underwriting engagements signed for $700 million project finance

facility for Platreef’s Phase 2 expansion

In December 2023, Ivanplats closed a senior debt facility with Societe Generale

and Nedbank Limited to fund Phase 1 construction. A total of $100 million was

drawn from the Phase 1 facility.

Following completion of the updated Phase 2 feasibility study, as announced on

February 18, 2025, Ivanhoe Mines has been focused on arranging an enlarged

project finance package to cover the majority of the capital requirements for the

Phase 2 expansion.

In late Q4 2025, credit approvals were received and underwriting engagements

were signed with Societe Generale, Absa Bank Limited and Nedbank Limited for

the $700 million Phase 2 senior project finance package. Signing of the Phase 2

senior project finance facilities is expected in the coming weeks. The Phase 2

facility will amend and upsize the Phase 1 facility, resulting in approximately $600

million of additional capital.

Financing for the future Phase 3 expansion is expected to be underpinned by

cash flow generated from Platreef’s Phase 1 and 2 operations.

The Platreef Mine is set to be one of the largest and lowest-cost

producers of platinum, palladium, rhodium, and gold, with nickel and

copper by-products.

On February 18, 2025, two independent studies were completed on the three-

phase development of the Platreef Mine. This included an updated Feasibility

Study on the Phase 2 expansion to 4.1 Mtpa of processing capacity, as well as a

Preliminary Economic Assessment covering a new Phase 3 expansion to 10.7

Mtpa of processing capacity. The excellent results from both studies reinforce the

multi-generational Platreef Mine's industry-leading margins.

The Platreef Mine is projected to be the lowest-cost primary platinum-group-

metals producer globally. The Phase 2 life-of-mine total cash cost is estimated to

be $599 per ounce of platinum, palladium, rhodium and gold (3PE+Au), net of

6

nickel and copper by-product credits. Life-of-mine total cash costs are projected

to fall further to $511 per ounce of 3PE+Au following the Phase 3 expansion. This

compares very favourably with a basket spot price of approximately $2,500 per

ounce of 3PE+Au, as at January 12, 2026. The Platreef Mine’s low cash costs are

primarily due to its unique thick orebody, which enables economies of scale, as

well as the high grades of nickel and copper that are payable by-products.

The Phase 2 expansion is expected to increase annualized production by almost

five-fold to over 460,000 ounces of 3PE+Au, plus approximately 9,000 tonnes of

nickel and 6,000 tonnes of copper. The Phase 3 expansion further doubles

annualized production to over 1 million ounces of 3PE+Au, plus approximately

22,000 tonnes of nickel and 13,000 tonnes of copper. The Phase 3 expansion is

expected to rank the Platreef Mine as one of the world’s largest primary platinum

group metal producers on a platinum-equivalent basis.

Significant increase in platinum and palladium prices boosts project

value to well over $5.0 billion

The long-term price assumptions for platinum and palladium in the 2025 Platreef

Integrated Development Plan (2025 IDP), filed on March 31, 2025, were $1,200 and

$1,130 per ounce, respectively. In the 2025 IDP, platinum and palladium together

accounted for approximately 60% of total project revenue, with the remaining 40%

from nickel, rhodium, copper, and gold.

Following the recent rise in precious metals prices, the current spot prices for

platinum and palladium are approximately 96% and 67% higher than those used

in the 2025 IDP, respectively. In addition, gold, rhodium, gold, copper and nickel

prices are also higher by approximately 110%, 90%, 40% and 5%, respectively.

In reference to the sensitivity tables in the 2025 IDP, and accounting for only the

increase in platinum and palladium prices at current prices, the net present value

(NPV8%) of the Phase 2 feasibility study at current spot prices is over 70% higher,

at approximately $2.7 billion. In addition, the sensitivity tables in the Preliminary

Economic Assessment (PEA) for the Phase 3 expansion indicate that the NPV8%

increases by approximately 60%, to over $5.0 billion. This is based on platinum

and palladium price assumptions of $1,550 and $1,700 per ounce, respectively.

NPV8% assumptions for platinum in the 2025 IDP don’t exceed $1,550 per ounce.
