Ivanhoe Mines, listed on the TSX, has announced that a new step-out hole – drilled 5,4 km west of the present boundary of Kakula’s current inferred resources – intersected a relatively shallow, 16,3-m zone of typical Kakula-style, chalcocite-rich copper mineralisation similar to holes drilled in the centre of the high-grade Kakula deposit. The deposit forms part of the company’s Kamoa-Kakula copper project in the DRC’s Katanga Province.
The DD1124 discovery hole is 3,8 km west of the current limit of Kakula drilling and 4,1 km west of the last drill hole with returned assays – DD1093 – that was announced on January 23 this year.

The target area where DD1124 was drilled – now named Kakula West – was selected by the Kamoa-Kakula geological team at the intersection of the axis of the interpreted Kakula trend with a south-westerly/north-easterly-trending antiform (the Kakula West antiform).
DD1124 intersected 16,3 m of visually moderate-strong chalcocite copper mineralisation, similar to the mineralisation encountered within the core of the chalcocite-rich Kakula deposit, beginning at a downhole depth of 422,2 m (410 m below surface). This included a 4,0-m zone of strong-to-very-strong mineralisation beginning at a downhole depth of 432,4 m.
Up to five rigs are being mobilised to fast-track the drilling at the Kakula West discovery.
Hole DD1124 has extended the length of the Kakula mineralised trend to approximately 10,1 km, essentially doubling the previously estimated strike length of 5,5 km.
The Kamoa-Kakula project, a joint venture between Ivanhoe Mines, Zijin Mining and the DRC government, is located near the mining centre of Kolwezi on the Central African Copperbelt in the DRC.
“In the mining exploration business, the very idea that a crew would drill a step-out hole almost four kilometres away from the last known mineralisation is virtually unheard of,” commented Ivanhoe’s Executive Chairman, Robert Friedland.
“Nonetheless, our geologists and independent advisors have become so confident in the proven consistency of Kakula’s chalcocite-rich mineralisation that they expected we would find more thick, near-surface, Kakula-style mineralisation in the vicinity of where it actually was discovered. The remarkable success with DD1124 is further validation of our team’s judgment and expertise.”
