Ivanhoe Mines responds to inaccuracies made in a press

release by Zijin Mining about Kamoa-Kakula’s operations

■

Ivanhoe Mines to provide a detailed update on Kamoa-Kakula

operations by Tuesday, May 27, 2025

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

OTCQX: IVPAF) today provides clarification to inaccuracies made in a press

release by Zijin Mining released earlier today. The press release was made in

relation to the temporary suspension of operations at the Kakula underground

mine, as announced by Ivanhoe Mines on Tuesday, May 20, 2025, at the Kamoa-

Kakula Copper Complex in the Democratic Republic of the Congo.

The press release by Zijin Mining refers to “…multiple roof-falling and rib-spalling

in the eastern section of the [Kakula] mine.” Ivanhoe Mines does not agree with

this statement.

Ivanhoe Mines and Kamoa Copper senior management, supported by geotechnical

specialists, continue to conduct a thorough inspection of the Kakula underground

mine, which commenced on May 20, 2025. The inspection is ongoing and has been

advancing further into the eastern section of the mine. Results so far show that

there is no evidence of collapsing stopes or structural pillars.

Preliminary indications suggest that seismic activity, which was experienced

during the last week and has subsequently subsided, resulted in a redistribution

of forces underground and caused “scaling”, or rock falls, from the sidewalls of

certain mining areas.

The operational teams are currently focused on safely repairing damage caused to

the cables and pipework that support the underground pumping infrastructure.

Once this activity is complete, focus will shift to returning to normal mining

operations starting with the western side of the Kakula Mine.

Once the underground investigation is completed, Ivanhoe Mines will determine

whether the temporary suspension of underground operations will impact annual

production guidance of the Kamoa-Kakula Mining Complex.

Ivanhoe Mines will provide a more detailed update by Tuesday May 27, 2025.
