Riyadh, Saudi Arabia--(Newsfile Corp. - January 8, 2024) - Ivanhoe Mines' (TSX: IVN) (OTCQX: IVPAF) Executive Co-Chair Robert Friedland and President Marna Cloete announced today, ahead of the 2024 Future Minerals Forum at the King Abdulaziz International Conference Centre in Riyadh, Saudi Arabia, that the Kamoa-Kakula Copper Complex in the Democratic Republic of the Congo (DRC) produced 393,551 tonnes of copper in concentrate in 2023, inside the 2023 production guidance range of 390,000 to 430,000 tonnes. Kamoa-Kakula's 2023 production achievement represents a year-over-year increase of 18%.

The 2024 annual production guidance for Kamoa-Kakula is estimated at between 440,000 to 490,000 tonnes of copper in concentrate, following the anticipated completion of the Phase 3 concentrator during the third quarter of 2024.

2024 Production Guidance for the Kamoa-Kakula Copper Complex

Kamoa-Kakula's 2024 production guidance is based on several assumptions and estimates as of December 31, 2023, including among other things, assumptions about the timing for the completion and ramp-up of the new 5-million-tonne-per-annum Phase 3 concentrator. Guidance involves estimates of known and unknown risks, uncertainties and other factors that may cause the actual results to differ materially.

All figures are on a 100%-project basis and metal reported in concentrate is before refining losses or payability deductions associated with smelter terms.

Ivanhoe Mines will provide 2024 guidance ranges for C1 cash costs (C1) per pound of payable copper and capital expenditure in its year-end financial results, which will be released on February 26, 2024. Ivanhoe will provide further guidance on Kipushi and Platreef, which are expected to be commissioned in Q2 2024 and Q3 2024, respectively.

Kamoa-Kakula produced 393,551 tonnes of copper in 2023, an increase of 18% compared with 2022

Kamoa-Kakula produced 393,551 tonnes of copper in 2023, achieving its production guidance of 390,000 to 430,000 tonnes. Guidance was achieved following the successful ramp-up of Kamoa Copper's debottlenecking program, which was completed ahead of schedule on February 27, 2023.

During 2023, Kamoa-Kakula Phase 1 and 2 concentrators milled approximately 8.5 million tonnes of ore at an average feed grade of 5.2% copper, producing 824,382 dry metric tonnes of copper concentrate. Copper flotation recoveries for the year averaged 87.4%, above the Phase 1 and 2 concentrator design recovery rate of 86.0%.

During the fourth quarter, a total of 2.1 million ore tonnes were milled at an average feed grade of 4.9% copper, producing 92,215 tonnes of copper in concentrate. Quarterly production was impacted by intermittent grid instability, particularly in November where plant utilization was significantly hampered by unplanned outages.

As with previous quarters, ore is drawn as required from surface stockpiles to maximize copper production. Kamoa-Kakula's high- and medium-grade ore surface stockpiles totaled approximately 4.13 million tonnes at an estimated, blended average grade of 3.5% copper. Contained copper in the stockpiles at the end of December totaled more than 143,000 tonnes.

After year-end, a daily milling record was achieved on January 1, 2024. 31,084 tonnes of ore were processed by the Phase 1 and 2 concentrators over 24 hours, which is equivalent to an annual milling rate of 10.4 million tonnes (after accounting for availability).

Kamoa Copper has been working extensively with DRC's state-owned power company, La Société Nationale d'Electricité (SNEL), to identify the causes of the instability across the southern DRC's grid infrastructure and to identify long-lasting solutions.

In December 2023, SNEL and Ivanhoe Mines Energy DRC, a subsidiary of Kamoa Holding Limited, signed an amendment to the existing financing agreement to fund the identified infrastructure upgrades. The original financing agreement consisted of a loan of up to $250 million to fund the refurbishment of 78 megawatts (MW) of generation capacity at the Mwadingusha dam and 178 MW of generation capacity from Turbine #5 at the Inga II dam. The refurbishment of the Mwadingusha facility was completed in September 2021, and the refurbishment of Turbine #5 at Inga II is on schedule to be completed in the fourth quarter of 2024.

The amendment to the financing agreement expands the loan up to a total of $450 million. The funding will be assigned specifically to grid infrastructure upgrades, such as an increase in grid capacity between Inga and Kolwezi, a new harmonic filter at the Inga Converter Station, as well as a new static compensator at the Kolwezi Converter Station. As with the existing financing agreement, the $200 million in additional funding by Ivanhoe Mines Energy to SNEL bears interest at the Secured Overnight Financing Rate (SOFR) plus 3% and will be repaid via a 40% discount on the tariff of grid energy consumed by Kamoa-Kakula. Mobilization of resources is underway, with project delivery expected to take place over the next 18 months.

In addition, Kamoa Copper's engineering team is currently expanding the on-site backup generation capacity to ensure there is full on-site redundancy for the current Phase 1 and 2 operations, as well as future Phase 3 operations. On-site backup-power generation capacity is set to increase, via a phased roll-out, from the current 48 MW to a total of over 200 MW in time for the completion of the Phase 3 smelter in Q4 2024. An additional 30 MW of installed generation capacity is expected to be fully commissioned early in Q2 2024, with a further 50 MW commissioned by the end of the quarter. This will bring backup generation capacity to 128 MW, which is enough for the combined Phase 1, 2 and 3 concentrators to operate. The generator farm sites are being built adjacent to the Phase 1 and 2 concentrators, and smelter at Kakula as well as adjacent to the Phase 3 concentrator at Kamoa.

Negotiations to source up to an additional 30 MW of power from the Zambian grid interconnector are complete, with the delivery of power expected to commence imminently. In the longer term, power supplied via the Zambian interconnector is expected to increase up to 100 MW.
