New discovery hole intersects a shallow, 3.8-kilometre extension
– now known as Kakula West – of the Kakula Copper Discovery
at the Kamoa-Kakula Project
Length of copper-rich mineralized system at Kakula
essentially doubled to more than 10 kilometres
and remains open for expansion
Five of 14 drill rigs now on site targeting additional
Kakula West drilling and high-priority targets
on the 400-square-kilometre project
KOLWEZI, DEMOCRATIC REPUBLIC OF CONGO – Ivanhoe Mines (TSX: IVN; OTCQX: IVPAF)
Executive Chairman Robert Friedland and Chief Executive Officer Lars-Eric Johansson
announced today that a new step-out hole – drilled 5.4 kilometres west of the present boundary
of Kakula’s current Inferred Resources – intersected a relatively shallow, 16.3-metre zone of
typical Kakula-style, chalcocite-rich copper mineralization similar to holes drilled in the centre of
the high-grade Kakula Deposit on the company’s Tier One Kamoa-Kakula Copper Project.
The DD1124 discovery hole is 3.8 kilometres west of the current limit of Kakula drilling and 4.1
kilometres 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 southwesterly-northeasterly-trending antiform (the Kakula West antiform). DD1124 intersected
16.3 metres of visually moderate-strong chalcocite copper mineralization, similar to the
mineralization encountered within the core of the chalcocite-rich Kakula Deposit, beginning at a
downhole depth of 422.2 metres (410 metres below surface), which included a 4.0-metre zone of
strong-to-very-strong mineralization beginning at a downhole depth of 432.4 metres (see Figure
1). Assays for DD1124 are expected in approximately two weeks. Up to five rigs are being
mobilized to fast-track the drilling at the Kakula West discovery.
Hole DD1124 now has extended the length of the Kakula mineralized trend to approximately 10.1
kilometres (see figures 2 and 3), essentially doubling the previously estimated strike length of 5.5
kilometres contained in Ivanhoe’s January 23, 2017 news release. The continuing success also
means that the discovery has grown to become six kilometres longer than the deposit’s 4.1-
kilometre strike length that was used in calculating the initial Kakula resource estimate in
October 2016.
The Kakula Discovery remains open along a westerly-southeasterly strike (see Figure 2).
Importantly, the chalcocite-rich zone of mineralization in DD1124 was intersected at a depth of
approximately 400 metres, indicating that the Kakula mineralized zone extends significantly
closer toward the surface in the area around the new discovery hole (see Figure 4).

The Kamoa-Kakula Project, a joint venture between Ivanhoe Mines, Zijin Mining and the DRC
government, is near the mining centre of Kolwezi on the Central African Copperbelt in the
Democratic Republic of Congo (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 mineralization is virtually unheard of,” Mr. Friedland
said.
“Nonetheless, our geologists and independent advisors have become so confident in the proven
consistency of Kakula’s chalcocite-rich mineralization that they expected we would find more
thick, near-surface, Kakula-style mineralization in the vicinity of where it actually was discovered.
The remarkable success with DD1124 is further validation of our team’s judgment and expertise.”
Mr. Friedland added: “Bear in mind that the Kakula Discovery now is vastly larger and more
important than it was last year when Kamoa-Kakula was independently ranked among the 10
largest copper deposits in the world. In fact, the resource estimate that we announced for Kakula
last October only covers approximately 40% of the presently defined 10.1-kilometre strike length
of Kakula’s mineralized trend.”
Expanded exploration program now testing Kamoa-Kakula grass-roots targets
Ongoing studies have highlighted numerous Kakula-style targets to the west and east of the
Kakula Dome and elsewhere in the 400-square-kilometre Kamoa-Kakula Project Area. The Kakula
West target was the first of these to be tested.
“The Kamoa-Kakula exploration team is continuing to enhance its understanding of the unique
geological controls influencing the project’s very-high-grade copper mineralization,” Mr.
Friedland said.
In response to the ongoing exploration success, Ivanhoe Mines and Zijin Mining have accelerated
the Kamoa-Kakula exploration program with the mobilization of additional contractor drill rigs
that has expanded the available fleet to 14 rigs.

As shown in Figure 4, the Kakula Deposit is a gently-dipping blanket of thick, chalcocite-rich copper mineralization. Initial mine
development is planned to focus on the flat, near-surface mineralized section (highlighted in the inset) which, along the deposit’s axis,
has mineralized zones ranging between 7.1 and 11.7 metres thick and grading between 8.11% and 10.35% copper, at a 3% copper cut-off.

Stephen Torr, P.Geo., Ivanhoe Mines’ Vice President, Project Geology and Evaluation, and a
Qualified Person under the terms of National Instrument 43-101. Mr. Torr has verified the
technical data disclosed in this news release.
Ivanhoe Mines maintains a comprehensive chain of custody and QA-QC program on assays from
its Kamoa-Kakula Project. Half-sawn core is processed at Kamoa-Kakula’s on-site preparation
laboratory and prepared samples then are shipped by secure courier to Bureau Veritas Minerals
(BVM) Laboratories in Australia, an ISO17025-accredited facility. Copper assays are determined
at BVM by mixed-acid digestion with ICP finish. Industry-standard certified reference materials
and blanks are inserted into the sample stream prior to dispatch to BVM. For detailed information
about assay methods and data verification measures used to support the scientific and technical
information, please refer to the January 2017 technical report on the Kamoa-Kakula Project titled
