RIYADH, SAUDI ARABIA – Ivanhoe Mines’ (TSX: IVN; OTCQX: IVPAF) Executive

Co-Chair Robert Friedland and President Marna Cloete announced today, ahead

of the 2023 Future Minerals Forum at the King Abdulaziz International Conference

Centre in Riyadh, Saudi Arabia, that the Kamoa-Kakula Mining Complex in the

Democratic Republic of Congo (DRC) produced 333,497 tonnes of copper in

concentrate in 2022, achieving the upper-end of the original 2022 production

guidance range of 290,000 to 340,000 tonnes. Kamoa-Kakula’s 2022 production

achievement represents a year-over-year increase of 215%.

The 2023 annual production guidance for Kamoa-Kakula is estimated at between

390,000 to 430,000 tonnes of copper in concentrate, following the anticipated

completion of the debottlenecking program early in the second quarter of 2023.

Mr. Friedland commented: “Kamoa-Kakula has firmly established a track record

of excellence during the development of Phase 1 and Phase 2 operations, which

has led to an industry-leading growth profile in terms of copper production that

will continue as we bring Phase 3 online. Kamoa-Kakula also stands out among

its peers as one of the few mining operations worldwide to strongly deliver on its

original 2022 production guidance, which is a further testament to the team of

engineers and contractors who commissioned the Phase 2 concentrator several

months ahead of schedule.”

“With the Phase 3 expansion well on track, including the integration of Africa's

largest single-line blister-copper flash smelter, Kamoa-Kakula is poised to

become one of the world's leading producers of vital copper metal for global

markets ... a producer that will have one of the lowest, if not the lowest, carbon

footprints in the industry. Ivanhoe Mines looks forward to a long, prosperous

partnership with the Democratic Republic of Congo government, the Congolese

people, our joint-venture partners, and the international investors that have been

integral in making these exceptional achievements possible.”

2023 Production Guidance for the Kamoa-Kakula Mining Complex

Kamoa-Kakula’s 2023 production guidance is based on several assumptions and

estimates as of December 31, 2022, including among other things, assumptions

about the timing for the completion of the debottlenecking program. Guidance

involves estimates of known and unknown risks, uncertainties and other factors

that may cause the actual results to differ materially.

Kamoa-Kakula 2023 Guidance

Contained copper in concentrate (tonnes) 390,000 - 430,000

All figures are on a 100%-project basis and metal reported in concentrate is before refining losses or

payability deductions associated with smelter terms.

Kamoa-Kakula produced 333,497 tonnes of copper in 2022, an

increase of 215% compared with 2021

Kamoa-Kakula’s 2022 production guidance was raised from an initial range of

290,000 to 340,000 tonnes, following the successful ramp-up of Kamoa Copper’s

Phase 2 concentrator plant, which was commissioned several months ahead of

schedule and declared commercial production on April 7, 2022.

During the fourth quarter, Kamoa-Kakula produced 92,761 tonnes of copper.

Kamoa-Kakula also reported 93,288 tonnes of copper floated, which includes the

contained copper still in the circuit that was floated, but has not yet been filtered

to produce a final concentrate. As of December 31, 2022, there was a balance of

approximately 5,670 tonnes of copper in the circuit, which will be filtered into a

final concentrate once the debottlenecking program is complete. For the full year

of 2022, in line with the Kamoa-Kakula’s upper end of guidance, 338,087 tonnes of

contained copper were floated.

The difference between floated and filtered copper arises from the current

bottleneck in concentrate filter capacity, as the Phase 1 and 2 milling and

flotation circuits continue to operate above design capacity. Floated copper is

temporarily stored as a slurry in a fully-lined pond, which will be reclaimed into

the concentrate thickener and filter press once the fourth Larox filter press is

installed as part of the debottlenecking program.

Kamoa Copper’s previously announced debottlenecking program is over 90%

complete and is progressing ahead of schedule. All the major equipment for the

program, including the fourth Larox filter press from Metso Outotec of Espoo,

Finland, has been delivered to the site. The final step of installation will take place

over the next few months, with cold commissioning targeted to take place in April

2023.

The new concentrate thickener nears completion. Once complete, the

Phase 1 and 2 concentrators are expected to reach a combined processing

capacity of 9.2 million tonnes per annum.

In the foreground, the expansion of the concentrate storage and dispatch

warehouse is nearing completion. The fourth Larox filter has been

delivered to site and will soon be installed at the rear of the facility.

As part of the debottlenecking program, the new scavenger-cleaner

flotation cell (circled in red) on the Phase 1 concentrator is undergoing

final installation.

The debottlenecking program will increase the combined processing capacity of

the Phase 1 and Phase 2 concentrator plants to approximately 9.2 million tonnes

per annum and increase the rate of copper production to approximately 450,000

tonnes per annum.

During 2022, the Kamoa-Kakula Mining Complex milled approximately 7.1 million

tonnes of ore at an average feed grade of 5.5% copper and produced 333,497

tonnes of copper in concentrate. A total of 2.0 million ore tonnes were milled

during the fourth quarter at an average feed grade of 5.4% copper.

Tonnes of ore milled in the fourth quarter were slightly lower by approximately

3.5%, on a quarter-on-quarter basis due to intermittent electrical power supply

disruptions on the DRC grid. Kamoa Copper is working with the DRC state-owned

power utility, SNEL, to minimize any future disruptions to operations.

On December 27, 2022, a total of 27,424 dry tonnes of ore were milled through the

Phase 1 and 2 concentrators ̶ a daily record for both facilities. This is equivalent

to an milling rate of 9.1 million tonnes per annum (after accounting for

availability).

A total of 120,000 tonnes were drawn from the run-of-mine stockpiles in the fourth

quarter. While the ongoing expansion of underground infrastructure at the Kakula

Mine takes place, ore continues to be drawn periodically from the stockpile to

maximize copper production, as the concentrators are currently operating over

design capacity.

The recently completed east truck tip and bin at the Kakula underground

mine will increase mining rates to feed the Phase 1 and 2 concentrators.

Kamoa-Kakula’s high- and medium-grade ore surface stockpiles totaled

approximately 4.08 million tonnes at an estimated, blended average grade of

4.05% copper. Contained copper in the stockpiles at the end of December totaled

6

more than 165,000 tonnes (the current copper price is approximately $8,600 per

tonne).

Copper flotation recoveries during 2022 from the Phase 1 and 2 concentrators

averaged 86%.

The Kamoa Copper process engineering team, together with several

internationally-recognized external metallurgy specialists, continue to investigate

the feasibility of new technologies to economically recover additional copper

from the tailings stream of the Phase 1 and 2 concentrators, to potentially

increase overall recoveries above Kamoa-Kakula’s 86% design target.

The Kamoa-Kakula 2023 Integrated Development Plan expected to be

released later this month, in addition to cash cost and capital

expenditure guidance

An updated 2023 Integrated Development Plan (Kamoa-Kakula 2023 IDP) for the

life-of-mine of the Kamoa Kakula Mining Complex, including both the Phase 3 and

Phase 4 expansions, as well as the smelter, is expected to be released during the

week of January 30, 2023.

Following the publication of the Kamoa-Kakula 2023 IDP, Ivanhoe Mines also will

provide a guidance range for C1 cash costs (C1) per pound of payable copper for

2023, as well as updated capital cost guidance for 2023 and 2024 across the

Kamoa-Kakula, Platreef and Kipushi projects.

Safety briefing held on the construction site of the Phase 3 concentrator.

To date, the construction sites for the Phase 3 concentrator and smelter, as

well as the housing and community projects have achieved zero recordable

injuries and an impressive 7,486,670 hours free of lost time injury (LTI).
