Drill assays confirmed the Kakula West zone as another high-grade copper discovery on the Kamoa-Kakula property in the Democratic Republic of the Congo, Ivanhoe Mines Ltd. said April 10.
The Kamoa-Kakula project is a joint venture with Zijin Mining Group Co. Ltd. and the DRC government, with Ivanhoe Mines acting as operator.
Discovery hole DD1124 at Kakula West returned a highlight of 8.86 meters (true width) grading 5.83% copper, including a 6.14-meter subinterval grading 6.84% copper, at a cutoff of 2.5% copper.
The drill hole returned 16.05 meters grading 4.14% copper at a 1.0% copper cutoff, in line with the company's March announcement of the new zone located 3.8 kilometers west of previous drilling.
Ivanhoe Mines also reported that two new step-out holes drilled west of the Kakula West discovery hole intersected Kakula-style, chalcocite-rich copper mineralization and extended the length of the mineralized system by another 800 meters, to a total of approximately 11 kilometers.
The Kakula deposit had been defined along a strike length of 4.1 kilometers when the initial resource estimate was completed October 2016. An updated resource estimate is anticipated in May.
There are 14 drill rigs in operation at the site, with testing of high-priority satellite drill targets scheduled to start soon.
