Ivanhoe has updated its copper reserves estimates at its Kamoa and Kakula copper projects in Congo.
The miner announced that its Kakula project, which is being fast-tracked to produce its first copper concentrate by Q3 2021, will likely produce around 3.8mn mt of ore annually. According to Ivanhoe’s latest estimates, copper reserves at Kakula at a 1pc cut off totaled 627mn mt of which 17.1mn mt had a 2.74pc copper grading. At the same cut off the inferred mineral resources were 104mn mt with 1.6mn mt at a 1.61pc copper grading.
The combined new indicated mineral resource at the Kamoa-Kakula copper projects at a 1pc cut off total 1.387bn mt of copper with 38mn mt at 2.72pc copper grading. At the same 1pc cut off the combined inferred mineral resources totaled 339mn mt with 5.6mn mt at 1.68pc copper grading.
At a 3pc cut off the combined indicated mineral resources for the two projects totaled 423mn mt with 10mn mt at 4.68pc copper grading, while the inferred combined mineral resources totaled 17mn mt with 3.51pc copper grading at 589,670mn mt.
