Kamoa Copper Achieves 33,379 Tonnes of Copper Production During Month of October

For the second month in a row, Kamoa-Kakula is producing at an annualised rate in excess of 400,000 tonnes of floated and filtered copper

De-bottlenecking program is near 70% complete, to further increase annualized production to approximately 450,000 tonnes of copper

New daily milling record achieved at Kamoa-Kakula, equivalent to an annual milling rate of 9.3 million tonnes of ore per annum

Ivanhoe Mines to issue Q3 2022 financial results and host conference call for investors on November 14

Kolwezi, Democratic Republic of Congo--(Newsfile Corp. - November 8, 2022) - Ivanhoe Mines (TSX: IVN) (OTCQX: IVPAF) Co-Chairs Robert Friedland and Yufeng "Miles" Sun are pleased to announce today that the Kamoa-Kakula Mining Complex in the Democratic Republic of Congo produced 33,379 tonnes of filtered copper in concentrate during the month of October.

At the end of October, there was an additional 5,786 tonnes of floated, but not yet filtered, copper in inventory. This marks the second month in a row that floated and filtered copper production from the Kamoa-Kakula Mining Complex has exceeded 400,000 tonnes per annum on an annualised basis.

The Phase 1 and 2 milling and flotation circuits continue to operate in excess of design capacity. The difference between floated, and subsequently, filtered copper arises from the current bottleneck in concentrate thickening and filter capacity at the tail end of the processing circuit. Excess floated copper is currently being temporarily stored as a slurry in a fully-lined pond adjacent to the Phase 1 and 2 concentrators. The unfiltered copper in inventory will be reclaimed into the concentrate thickener and filter press once capacity is expanded following the installation of a new concentrate thickener and Larox filter press, as part of the ongoing de-bottlenecking program.

The previously announced de-bottlenecking program is approximately 70% complete and is tracking ahead of schedule. The program, which is expected to be complete in Q2 2023, will increase the combined design processing capacity of the Phase 1 and Phase 2 concentrator plants from 7.6 million tonnes per annum to approximately 9.2 million tonnes per annum.

Kamoa-Kakula's Phase 1 and 2 concentrators milled 713,439 tonnes of ore in October, equivalent to a run rate of 8.6 million tonnes per year. During the month, the processing team at Kamoa-Kakula stress-tested the operating rate of the Phase 2 concentrator and over a 24-hour period achieved a record of approximately 14,000 tonnes of ore milled. This is equivalent to a milling rate from both the Phase 1 and 2 concentrators of 9.3 million tonnes per annum (after accounting for availability).

The installation of the scavenger-cleaner flotation cell at the Phase 2 Concentrator is nearing completion. The de-bottlenecking program is expected to be complete in Q2 2023.

About Ivanhoe Mines

Ivanhoe Mines is a Canadian mining company focused on advancing its three principal projects in Southern Africa: the expansion of the Kamoa-Kakula Mining Complex in the Democratic Republic of Congo, the construction of the tier-one Platreef palladium-rhodium-platinum-nickel-copper-gold project in South Africa; and the restart of the historic ultra-high-grade Kipushi zinc-copper-germanium-silver mine, also in the Democratic Republic of Congo.

The Kamoa-Kakula Mining Complex is the highest-grade and fastest growing of the top 10 copper mining operations in the world. Copper concentrates were first produced in May 2021 and, through on-going phased expansions, the Kamoa-Kakula Mining Complex is positioned to become one of the world's largest copper producing operations. Kamoa-Kakula's 2022 production guidance is between 310,000 to 340,000 tonnes of copper in concentrate.

The Kamoa-Kakula Mining Complex is powered by clean, renewable hydro-generated electricity and is among one of the world's lowest greenhouse gas emitters per tonne of copper metal produced.

The Kamoa-Kakula Mining Complex is operated by Kamoa Copper, a joint venture between Ivanhoe Mines (39.6%), Zijin Mining Group (39.6%), Crystal River Global Limited (0.8%) and the DRC government (20%).

Ivanhoe Mines is also exploring for new copper discoveries across its circa 2,400km2 of wholly-owned exploration licences in the Western Foreland, which are located adjacent to the Kamoa-Kakula Mining Complex in the Democratic Republic of Congo.
