Following the set up of an extra 72 MW of mills, the on-site backup energy capability of 135 MW is now enough to energy Kamoa-Kakula’s Section 1 and a pair of concentrators at full capability, Ivanhoe stated, including that the challenge staff stays on schedule to have 201 MW of put in on-site backup energy era capability by year-end.
New copper steering
For the 12 months, Ivanhoe now expects its copper focus manufacturing to take a seat between 425,000-450,000 tonnes as an alternative of 440,000-490,000 tonnes. By way of the primary three quarters, Kamoa-Kakula has produced 303,328 tonnes of copper in focus, together with 40,025 tonnes at a document every day manufacturing price of 1,334 tonnes in the course of the month of September.
Throughout the third quarter, the Section 1 and a pair of concentrators milled roughly 2.2 million tonnes of ore at a median feed grade of 4.9% copper. Quarterly copper manufacturing from the concentrators totalled 94,214 tonnes, at a median restoration price of 86.6%.
The Section 3 concentrator, which achieved business manufacturing in the course of the third quarter, milled roughly 1.1 million tonnes of ore predominantly from historic floor stockpiles at a median feed grade of two.6% copper. The concentrator added 22,099 tonnes of quarterly manufacturing at a restoration price of 79.9%, reflecting the continuing ramp-up.
Ivanhoe famous the Section 3 concentrator sustained enhancements in processing throughput and restoration charges following the commissioning of the fine-grinding mills in early September. Over the last week of the month, the concentrator milled 117,484 tonnes, which is equal to an annualized processing price of over 5.5 million tonnes each year.
Kamoa’s operations staff now expects to achieve the nameplate restoration price of 86% in the course of the fourth quarter, thereby reaching steady-state manufacturing. As well as, the staff can be concentrating on to extend the feed grade to the Section 3 concentrator as much as roughly 3% by the primary quarter of 2025, whereas ore reserves proceed to be developed in the direction of the higher-grade zones within the Kamoa 1 and Kamoa 2 underground mines.
Zinc goal revised
Along with copper, Ivanhoe has readjusted its 2024 zinc steering as a consequence of operational disruptions which have inhibited the nameplate throughput from being sustained each day on the Kipushi mine, additionally positioned within the DRC.
Since its first focus manufacturing this June, the Kipushi’s concentrator has continued to ramp up, with roughly 88,000 tonnes of stockpile ore milled in the course of the third quarter at a median feed grade of 27.1% zinc. Quarterly zinc manufacturing from the concentrator was 17,817 tonnes, at a median flotation restoration price of 72%. Exports of zinc focus additionally commenced in the direction of the tip of the quarter.
Nevertheless, the ramp-up of Kipushi’s concentrator to its annual steady-state manufacturing price of over 250,000 tonnes has been slower than anticipated. The corporate attributes this to 3 elements: increased iron content material of the Massive Zinc orebody, which was negatively impacting concentrator recoveries; ore feed into the dense media separation (DMS) circuit containing extra nice materials, which restricted throughput; and the rise in energy requirement, from 5 MW used throughout development to 18 MW for operations.
On account of these disruptions, the full-year manufacturing steering vary for Kipushi has been halved, from 100,000-140,000 tonnes of zinc in focus to 50,000-70,000 tonnes. Work is underway is to enhance the recoveries and improve the mine infrastructure.
In the meantime, Ivanhoe is implementing a debottlenecking program that is concentrating on a 20% enhance in concentrator processing capability to 960,000 tonnes of ore each year. This system is anticipated to be accomplished in mid-2025.
Ivanhoe Mines’ shares fell 3.5% to C$19.79 apiece by 3 p.m. in Toronto on the Q3 outcomes information launch. The corporate has a market capitalization of C$26.8 billion.
