Ivanhoe Mines announces Kamoa-Kakula achieved record copper

production of 35,856 tonnes in May

■

Monthly copper production equivalent to annual production of

approximately 430,000 tonnes

■

New daily ore milling record achieved at Kamoa-Kakula,

equivalent to an annual rate of approximately 9.8 million tonnes

■

Phase 1 and 2 concentrators continue to operate at above-design

copper recoveries

■

Phase 3 expansion and smelter advancing on schedule for first

production in Q4 2024

KOLWEZI, DEMOCRATIC REPUBLIC OF CONGO – Ivanhoe Mines (TSX: IVN; OTCQX:

IVPAF) Co-Chairs Robert Friedland and Yufeng “Miles” Sun announced today that the

Kamoa-Kakula Copper Complex in the Democratic Republic of Congo achieved a

monthly production record of 35,856 tonnes of copper in concentrate during May.

Copper production during April was 34,826 tonnes of copper in concentrate, bringing

quarter-to-date production to 70,682 tonnes.

A new daily milling record of 29,366 tonnes of ore was also achieved by the Phase 1 and

2 concentrators. This is equivalent to an annual milling rate of 9.8 million tonnes per

annum (after accounting for availability). This record far exceeds the increased milling

capacity of 9.2 million tonnes per annum following the debottlenecking program of the

Phase 1 and 2 concentrators, which was completed in February 2023.

Average copper recoveries for the month were 87%, above the Phase 1 and 2

concentrator nameplate recovery rates.

Construction activities for the Phase 3 expansion, including the largest copper smelter

in Africa, with a capacity of 500,000 tonnes of 99+%-pure copper anodes, are advancing

on schedule for first production in the fourth quarter of 2024.

Concrete foundations for the two ball mills of the Phase 3 concentrator on the

left, with foundations for the flotation cells on the right. The first batch of ball mill

foundation steel is expected at site later this month. The first ball mill, supplied

by CITIC Heavy Industries of Luoyang, China, also is expected to be delivered

later this month.

Concrete foundations for the Phase 3 concentrator tailings thickener. Over 60%

of concrete has been poured to date and approximately 6,000 tonnes of the

required 7,100 tonnes of structural steel have been fabricated, 50% of which has

been shipped to site.

Steel erection of Kamoa-Kakula's direct-to-blister flash furnace and the electric

slag cleaning furnace. Overall smelter construction is now approximately 50%

complete. Fabrication of the anode furnaces, ball mill and SAG mill, also

manufactured by CITIC Heavy Industries, is complete with shipping expected

imminently.

Construction of new on-site accommodation. There are approximately 14,000

employees and contractors at site; approximately 97% of Kamoa’s employees are

Congolese.

Ivanhoe Mines is a Canadian mining company focused on advancing its three principal

projects in Southern Africa; the expansion of the Kamoa-Kakula Copper Complex in the

DRC, 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 DRC.

Ivanhoe Mines also is exploring for new copper discoveries across its circa 2,400km2 of

90-100% owned exploration licences in the Western Foreland, located adjacent to, or in

close proximity to, the Kamoa-Kakula Copper Complex in the DRC.
