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

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

Marna Cloete are delighted to announce that on November 18, 2025, the President

of the Republic of South Africa, Cyril Ramaphosa, officially opened the Platreef

platinum-palladium-nickel-rhodium-gold-copper mine. The opening ceremony

took place ahead of the 2025 G20 Summit in Johannesburg, South Africa,

scheduled from November 22 to 23, 2025.

A delegation of national, provincial, and local dignitaries attended the opening

ceremony, led by the President, and including former President and Ivanhoe

Mines board member, Kgalema Motlanthe, as well as Dr. Phophi Ramathuba,

Premier of Limpopo Province.

The delegation was greeted by board members and senior management from

Ivanhoe Mines and Ivanplats, representatives from Ivanplats’ historically

disadvantaged, broad-based, black economic empowerment (B-BBEE) partners,

and representatives from the Japanese partnership consortium, consisting of

ITOCHU Corporation, Japan Oil, Gas and Metals National Corporation (JOGMEC),

and Japan Gas Corporation.

President Ramaphosa first unveiled a commemorative plaque and conducted a

ribbon-cutting at the concentrator, marking the official opening of the Platreef

Mine, before pressing the button to start the concentrator’s operations. This was

followed by a ceremony attended by over 2,000 people, including Platreef’s

2

workforce, of which 70% are from local communities and nearly 30% are female.

Ivanhoe Mines’ Founder and Executive Co-Chairman Robert Friedland spoke as

follows (quoted verbatim):

“We are all bubbles in a stream ... when we first came here in the 1980s, this was

the Lebowa Homeland Administration, and we made an agreement with [the

administration] … there was a company here that controlled all of the mineral

rights called JCI, a division of the Anglo American corporation … we were

threatened and we were told that nothing would ever be mined here, and we were

told that it would be impossible to develop a mine … but if we ever did, Mr.

Davison [then CEO of JCI] said we would develop this mine over his dead body …

I learned that he passed away in June … I'm not sure whether he's going to

heaven or the other place … maybe that's yet to be decided … but I want to say

that when I met President Ramaphosa as a much younger man … I'm 75 years of

age now … I'm a grandfather … when I met him, he was also much younger …

and he inspired me and all of us in the vision of Nelson Mandela to change the

face of South Africa.

“This will be the largest mine in the African continent for precious metals …

today we just have Phase 1, the baby mine … the first little bubble … in two years,

the giant shaft will begin, the largest shaft in Africa … all of this is because of the

vision we received from President Ramaphosa in the early days.

“150,000 historically disadvantaged, local black people are actually equity owners

in this mine ... 26% of this mine is operated by independent trusts on behalf of

local people and over 60% of our workers are from this community ... and all of

our miners are proud South Africans ... I thank God for your efforts ... I thank all

of you and a humbly say I want to thank our Japanese partners who invested,

3

brought capital into this country ... I want to thank the leadership of first

President Kgalema Motlanthe and then President Cyril Ramaphosa ... thank you

very much ... God bless all of you who will make this mine live for another 200

years.”

Cyril Ramaphosa, President of the Republic of South Africa, also spoke at length

during the opening ceremony:

“The commencement of production at Platreef is in many ways a culmination of a

long journey that began with the initial exploration more than 27 years ago.

Robert said this as a baby step [for Ivanplats], but I see a giant step for the

community of Mokopane and a gigantic step for our country, South Africa, and

we should give a big round of applause for this progress. Today, having finally

reached the production phase, is a testament to decades of hard work, resilience,

and persistence. This is an important moment for Ivanplats, for the mining

industry, and for our country as a whole.

“This mine begins its life opening a new page in our country. This is the first mine

that is really opening with the full involvement of the community, not only as

workers but as equity owners, as owners of this wonderful resource that is going

to be mined here … so this mine is breaking new ground, it is breaking history,

and it is opening up a new chapter of how mining should really be done in our

country.”

Phase 1 operations by Ivanhoe Mines’ Founder and Executive Co-

Chairman, Robert Friedland, President and Chief Executive Officer, Marna

Cloete, and Chairperson of Ivanplats, Dr. Patricia Makhesha.

During the ceremony, first concentrate was produced from the

Platreef Mine’s Phase 1 concentrator

The Platreef Mine’s Phase 1 concentrator commenced the final stages of hot

commissioning on October 29, 2025, with the first feed of platinum-palladium-

nickel-rhodium-gold-copper ore. The first production of concentrate took place

during the ceremony on November 18, 2025.

As announced on May 8, 2025, underground development of the thick, high-grade

Flatreef platinum-palladium-nickel-rhodium-gold-copper orebody on the 850-

metre level commenced on April 30, 2025. Since then, to October 30, 2025, a total

of 391 metres of reef development in ore has been completed, and of the total

21,702 tonnes of ore blasted, 15,369 tonnes have been hoisted to surface. Reef

development on the 750-metre level has also recently commenced. Development

7

ore continues to be hoisted to surface via Shaft #1 and stored in surface

stockpiles. The lower-grade development ore stockpiles will be used to feed the

0.8-million-tonnes-per-annum (Mtpa) Phase 1 concentrator during the initial

stages of ramp-up.

Equipping of Shaft #3, which will more than quadruple available hoisting capacity

to up to 5 Mtpa, continues to progress well and is on schedule for completion and

commissioning in March 2026. Long hole stoping (production mining) is expected

to commence in early Q2 2026, once Shaft #3 is operational.

The underground delineation drilling program, which commenced last year ahead

of developing the first long-hole ore blocks, has progressed very well, with a total

of 16,110 metres drilled to date. All assays reconcile well with Ivanplats’

geological models and mine plan.

Recruitment continues ahead of the ramp-up of Phase 1, with the Ivanplats

workforce now over 2,200 employees and contractors, including more than 70%

locally based and 26% female. The workforce will continue to grow as the project

team has recently started development work on Phase 2.

infrastructure in the background. Once operational, the combined hoisting

capacity of all three shafts will be up to 13 Mtpa, enough to produce over 1

million ounces per year of platinum, palladium, rhodium, and gold, plus

significant additional nickel and copper.

Masodi Wastewater Treatment Works officially opened, an industry-

leading, public-private partnership to sustainably source water for the

Platreef Mine

On November 11th, 2025, the Masodi Wastewater Treatment Works, in Mokopane,

Limpopo Province, was officially opened. The opening ceremony was attended by

senior government officials, key private-sector leaders, and senior management

from Ivanplats. The state-of-the-art wastewater treatment works have significantly

improved sanitation and public health in Mokopane and surrounding

communities since its completion in 2024. Municipal wastewater is recycled at the

facility, enabling the water to be reused for industrial purposes. The wastewater

facility will also significantly benefit Mokopane’s local economy, enabling the

start-up and future expansions of the Platreef Mine, which otherwise would not be

possible in the water-scarce region. The Masodi Wastewater Treatment Works

was developed through a pioneering public–private partnership formed between

the Mogalakwena Local Municipality and Ivanplats.

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 mine and the 3.3-million-

tonne-per-annum Phase 2 concentrator. DRA Global was the EPCM contractor

that delivered the construction of 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 Q1 2026.

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

the shaft to a diameter of 10 metres will commence following the appointment of

the contractor in Q4 2025. Raise boring of Shaft #2 to its initial diameter of 3.1

metres was completed in Q4 2024.

Negotiations for Platreef’s Phase 2 project finance are advancing well

In December 2023, Ivanplats concluded a senior debt facility with Société

Générale and Nedbank Limited to fund the construction of Phase 1. An initial $70

million was drawn, with a further $30 million drawn in the second quarter of 2025.

Following the completion of the 4.1 Mtpa feasibility study, Ivanhoe Mines has

been focused on arranging an enlarged project finance package for the majority

of the expansion capital requirements for Phase 2.
