Ivanhoe Mines announces completion of hydropower ramp-up

of 178-megawatt Turbine #5 at Inga II

■

Initial 50 megawatts received at Kamoa-Kakula; expected to

increase to 100 megawatts by Q1 2026 as grid improvements

are completed, and 150 megawatts by 2027

■

Over 10 years of partnership between Ivanhoe Mines and

Société Nationale d'Electricité (SNEL) in the refurbishment of

250 megawatts of renewable, hydropower capacity

KOLWEZI, DEMOCRATIC REPUBLIC OF THE CONGO – Ivanhoe Mines (TSX: IVN)

(OTCQX: IVPAF) Executive Co-Chair Robert Friedland and President and Chief

Executive Officer Marna Cloete are delighted to announce that the first 50

megawatts (MW) of clean, hydroelectric power from the newly refurbished 178-

MW Turbine #5 at the Inga II dam is now being received at the Kamoa-Kakula

Copper Complex. The feed of hydroelectric power, from Inga II to Kamoa Kakula,

is expected to increase to 100 MW in Q1 2026 and then increase to 150 MW as

grid improvements are completed.

the DRC state utility, SNEL, in refurbishment and return to

operation of 250 MW of clean, hydropower capacity:

Initial 50 megawatts of clean, hydropower delivered to Kamoa-Kakula

from newly refurbished 178-megawatt Turbine #5 at Inga II

Installation of replacement mechanical and electrical equipment at Turbine #5 at

the Inga II hydroelectric facility was completed in Q3 2025, followed by

synchronization and energization of Turbine #5 in early Q4 2025. The newly

refurbished Turbine #5 has since ramped up to full capacity, delivering

approximately 180 MW of clean, hydroelectric power into the DRC grid. Of the 180

MW being delivered into the grid, Kamoa-Kakula is currently receiving an initial

50 MW, bringing its total domestically sourced power to approximately 110 MW,

as shown in Table 1. Hydroelectric power delivery to Kamoa-Kakula, from Turbine

#5, is expected to increase to 100 MW in Q1 2026 and to 150 MW thereafter as grid

upgrades are completed.

The grid improvement initiatives primarily focus on upgrades to substations at

Inga (SCI) and Kolwezi (SCK). The first upgrade, consisting of resistor banks at

the Inga substation, was completed in May 2025. Corresponding resistor

upgrades at the Kolwezi substation are expected to be completed imminently,

improving voltage stability to Kamoa-Kakula. In addition, the static compensator

at the Kolwezi substation is scheduled to be completed in early Q1 2026,

increasing the power delivery from Inga II to the Kamoa-Kakula up to 100 MW.

The remaining workstreams to upgrade the filter banks at SCI and SCK will occur

in phases over the next 18 months, ultimately increasing the total power received

from Turbine #5 to 150 MW during H1 2027. As shown in Figure 1, by the end of

2027, total domestically-sourced, renewable grid-supplied power is expected to

be approximately 210 MW.

The Inga II hydroelectric facility consists of eight turbines, with the

potential to generate up to 1.4 gigawatts of clean, hydroelectric power. Inga

II is located on the Congo River, the second-largest river in the world by

discharge. The refurbishment of Turbine #5 commenced in 2022.

About Ivanhoe Mines

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

principal operations in Southern Africa; the Kamoa-Kakula Copper Complex in

the DRC, the ultra-high-grade Kipushi zinc-copper-germanium-silver mine, also in

the DRC; and the tier-one Platreef platinum-palladium-nickel-rhodium-gold-

copper mine in South Africa.

Ivanhoe Mines is exploring for copper in its highly prospective, 54-100% owned

exploration licences in the Western Forelands, covering an area over six times

larger than the adjacent Kamoa-Kakula Copper Complex, including the high-
