Ivanhoe hails progress at Kamoa-Kakula, Platreef

Ivanhoe Mines (TSX:IVN; US-OTC: IVPAF) said that progress at its Kakula project, the first of multiple planned mining areas at Kamoa-Kakula in the Democratic Republic of the Congo, continues to move forward, with production slated for the third quarter of 2021.

Delivering full year results and an update on activities, the Canadian miner said once the ongoing definitive feasibility study for its Kakula copper mine is finished, the company would have “an increased level of accuracy” for the design, production schedule and expenditure for the initial phase of mine development.

Following the completion of basic procurement, as part of the imminent Kakula DFS, the mine’s initial processing plant capacity has increased from 3 million tonnes a year to 3.8 million tonnes a year.

The expansion in initial plant capacity will require boosting the number of people working on underground mining crews from 11 to 14 this year to ensure enough output to feed the expanded plant. More workers also will be needed to create pre-production stockpiles of about 1.5 million tonnes of high-grade ore and an additional 700,000 tonnes of material grading between 1% and 3% copper, Ivanhoe said.

In November, the Kamoa-Kakula team completed basic design and costing for Kakula’s initial mine and infrastructure, the first concentrator module and associated infrastructure.

The report pushed initial capital costs up to about US$1.3 billion — an 18% increase over planned costs.

Robert Friedland, who made his fortune from the Voisey’s Bay nickel project in Canada in the 1990s, has been working on Kamoa-Kakula for ten years.

Friedland believes the project, being developed in partnership with China’s Zijin Mining Group, will become the world’s second-largest copper mine.

According to an independent pre-feasibility study released last year, if all phases are completed, the operation is expected to reach peak annual production of more than 700,000 tonnes copper.

The updated resource estimate for the massive project, delivered last month, shows it holds 1.4 billion indicated tonnes grading 2.74% copper for 83.7 billion lb. copper and another 339 million inferred tonnes grading 1.68% copper for 12.5 billion lb. copper at a 1% cut-off grade.

Ivanhoe also highlighted that it is stepping up efforts to take advantage of soaring prices of platinum-group metals (PGMs), particularly palladium and rhodium. The two metals, broadly available at its 64%-owned Platreef project in South Africa, have benefitted from a global shortage triggered by their increasing use in catalytic converters that reduce harmful engine emissions. This has propelled the asset’s “metals-price basket” to a new, all-time high, Ivanhoe said.

The Vancouver-based company is fast-tracking a feasibility study on a smaller-scale, early-stage development plan using Shaft 1 as a production shaft at Platreef.
