Debottlenecking of Kamoa-Kakula’s Phase 1 and Phase 2

concentrators now complete ahead of schedule

■

Milling operations increased by 22% to 9.2 million tonnes of

ore per annum

■

Copper production capacity increases to 450,000 tonnes per

annum

HOLLYWOOD, FLORIDA — Ivanhoe Mines (TSX: IVN; OTCQX: IVPAF) Executive

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

32nd BMO Global Metals & Mining Conference that the debottlenecking of the

Kamoa-Kakula Copper Complex’s Phase 1 and 2 concentrators has been

completed ahead of schedule. The ongoing final installation and commissioning

of a fourth Larox filter press is the final step in the overall debottlenecking

program, which is expected to be completed in March 2023.

Mr. Friedland commented: "The operations team at Kamoa-Kakula continues to

exceed expectations ... once again delivering an important expansion project

ahead of schedule and on budget. We intend to reach a sustainable, annualized

production rate of 450,000 tonnes of copper during the second quarter, which is

an exceptional achievement considering we declared Phase 1 production at

Kamoa-Kakula, alongside our joint venture partners, Zijin Mining, less than two

years ago."

"Our dedicated team of engineers are determined to continue this record of

operational excellence as we execute the Phase 3 expansion. The project will

include the integration of Africa's largest direct-to-blister smelter complex and

will drive annualized production to over 600,000 tonnes of copper by early 2025 ...

continuing Kamoa-Kakula’s distinction as the fastest-growing, highest-grade

copper complex on our planet."

The debottlenecking program of Kamoa-Kakula's Phase 1 and Phase 2

concentrators is designed to increase the nameplate ore processing capacity by

22% from 7.6 to 9.2 million tonnes of ore per annum, increasing production

capacity up to approximately 450,000 tonnes per annum of copper in concentrate.

For comparison, Kamoa-Kakula produced 333,497 tonnes of copper in

concentrate in 2022.

Two scheduled plant shutdowns, to tie in the new debottlenecking equipment, are

now complete. The shutdown of the Phase 1 concentrator took place in January

2023, and the shutdown of the Phase 2 concentrator plant was completed on

February 22, 2023. The new equipment consists of new hydrocyclone systems,

new scavenger-cleaner flotation cells, a new concentrate thickener, as well as

upsized piping and pumping capacity.

The last outstanding action is the installation and commissioning of the fourth

Larox filter press, which sits at the end of the processing circuit. The filter press

has been lowered into position in the concentrate storage and dispatch

warehouse, and its installation and commissioning are anticipated to be complete

in March. The Phase 1 and Phase 2 concentrators are expected to be able to

sustain the new nameplate capacity of 9.2 million tonnes of ore per annum prior

to the fourth Larox filter press commissioning. The total capital cost for the

debottlenecking program was approximately US$50 million.

The Phase 1 concentrator has been operating at its new, sustained nameplate

capacity of 580 dry tonnes per hour since January 25, 2023; and at times

delivering as high as 590 dry tonnes per hour.

On February 25, 2023, within 12 hours of restarting, the Phase 2 concentrator has

also ramped up to its new, sustained nameplate capacity of 580 dry tonnes per

hour, or 9.2 million tonnes per annum.

The final installation of the Phase 2 concentrator’s scavenger-cleaner

flotation cell was completed on February 22. The commissioning of the

scavenger-cleaner flotation cell on the Phase 1 concentrator complete was

completed in January.

debottlenecking program.

debottlenecked Phase 1 and Phase 2 production capacity of approximately

450,000 tonnes of copper in concentrate per annum.
