Name of the Project
Kamoa-Kakula copper project.

Location
The project is located on the Central African Copperbelt, west of the Democratic Republic of Congo’s (DRC’s) Katanga mining region.

Client
Following the signing of a partnership agreement with the DRC government in November 2016, Ivanhoe and Zijin Mining now each hold an indirect 39.6% interest in the Kamoa-Kakula project, while Crystal River Global holds an indirect 0.8% interest and the DRC government a direct 20% interest.

Kamoa Holding has an indirect 80% interest in the tier-one Kamoa-Kakula copper project.

Project Description
The project has been independently ranked as the world’s largest high-grade copper discovery by international mining consultant Wood Mackenzie.

On May 17, 2017, Ivanhoe Mines announced that the company had completed an independently verified, updated mineral resource estimate for the Kamoa-Kakula copper project.

The new mineral resource estimate covers a strike length of about 7.7 km along the eastern section of the Kakula discovery. It boosts the tonnage of Kakula’s estimated indicated resources by 75%, compared with the October 2016 resource estimate, which covered a strike length of 4.1 km.

Kakula’s indicated mineral resources increased by 50-million tonnes to 116-million tonnes at 6.09% copper, at a 3% cutoff grade. This compares with 66-million tonnes at 6.59% copper estimated in October 2016, also at a 3% cutoff grade.

Kakula’s new estimated inferred mineral resources include an additional 12-million tonnes at 4.45% copper, at a 3% cutoff.

The new estimate further boosts the combined Kamoa-Kakula indicated mineral resources to about one-billion tonnes, at 3.02% copper, and another 191-million tonnes of inferred resources at 2.37% copper, at a 1.4% cutoff.

The preliminary economic assessment (PEA) results, finalised in December 2016, present two initial scenarios for development of the high-grade copper deposits at the project.

Scenario 1:
The development of a four-million-tonne-a-year Kakula Phase 1 mine at the Kakula deposit, in the southerly portion of the project’s discovery area. For this option, the PEA envisages an average production rate of 216 000 t/y of copper and peak copper production of 262 000 t by Year 3. In this option, the project has an initial mine life of 23 years.

Scenario 2:
Two mines producing a total of eight-million tonnes a year, comprising a two-phase sequential expansion of the proposed Kakula Phase 1 mine at the Kakula deposit and the Kansoko mine at the adjacent Kamoa deposit. The PEA envisages an average production rate of 292 000 t/y and peak production of 370 000 t by Year 7. In this option, the project has an initial mine life of 29 years.

Net Present Value/Internal Rate of Return
The option for a single four-million-tonne-a-year mine estimates an after-tax net present value (NPV), at an 8% discount rate, of $3.66-billion – an increase of 272% – compared with the after-tax NPV of $986-million projected in the March 2016 Kamoa prefeasibility study (PFS). The internal rate of return (IRR) of 38% is more than double the return that was estimated in the March 2016 PFS, with a payback of 2.3 years.

The option for two mines producing a total of eight-million tonnes a year forecasts an after-tax NPV, at an 8% discount rate, of $4.75-billion, an increase of 382%, compared with the after-tax NPV of $986-million estimated in the 2016 Kamoa PFS. The after-tax IRR is estimated at 34.6%, which is more than double the IRR of the 2016 Kamoa PFS, with a payback period of 3.5 years.

Value
The Kakula Phase 1 mine proposal estimates preproduction capital cost of $999-million. This is about $200-million less than previously estimated in the March 2016 Kamoa PFS.

In the Kakula Phase 1 mine and Kansoko mine proposal, the PEA estimates $999-million in capital costs.

Latest Developments
Ivanhoe Mines has received the final installment of $41.2-million from a subsidiary of Zijin Mining Group, as part of a strategic co-development agreement under which Zijin acquired 49.5% of Ivanhoe’s majority stake in Kamoa Holding for $412-million.

Zijin, through its subsidiary Gold Mountains International Mining Company, paid an initial $206-million in December 2015, followed by the payment of four scheduled tranches of $41.2-million each in March, July and October 2016, and February this year.

After the receipt of the fifth installment from Zijin, Ivanhoe’s consolidated working capital is about $325-million.
