MOKOPANE, SOUTH AFRICA – Robert Friedland, Executive Chairman of Ivanhoe Mines (TSX: IVN; OTCQX: IVPAF), and Lars-Eric Johansson, Chief Executive Officer, announced today that the company has approved the start of early-works construction for Shaft 2, which will be the main production shaft at the Platreef platinum-group metals, nickel, copper and gold mine now being developed in South Africa.
Ivanplats, Ivanhoe Mines’ 64%-owned subsidiary, is expected to begin the two-part, early-works program for Shaft 2 in Q2 2017. The program will consist of:
- excavation of a surface box cut to a depth of approximately 29 metres below surface; and
- construction of the concrete hitch (foundation) for the 103-metre-tall concrete headgear (headframe) that will house the shaft’s permanent hoisting facilities and support the shaft collar.
The early-works construction is expected to take approximately 12 months and cost approximately R70 million (US$5.5 million).
Shaft 2 will be located approximately 100 metres northeast of Shaft 1, where permanent sinking has been underway for eight months. Shaft 2, with an internal diameter of 10 metres, will be lined with concrete and sunk to a planned, final depth of more than 1,100 metres below surface. It will be equipped with two 40-tonne rock-hoisting skips capable of hoisting a total of six million tonnes of ore per year – which will be the single largest hoisting capacity at any mine in Africa. The headgear for the permanent hoisting facility was designed by South Africa-based Murray & Roberts Cementation.
“This is another key milestone in the building of a new, state-of-the-art underground mine in South Africa,” said Mr. Friedland. “Shaft 2 is the key to unlocking Platreef’s full potential and we believe that the time is right to prudently move forward with the development of this world-scale project.”
Dr. Patricia Makhesha, Ivanplats’ Managing Director, added: “We are committed to developing Platreef into South Africa’s next great platinum-group metals mine, generating widely shared economic benefits to the South African economy and helping to deliver important jobs, skills training and enterprise development opportunities to the communities in the Mokopane area.”

Shaft 1 sinking advancing at a rate of 45 to 50 metres per month
Shaft 1, with an internal diameter of 7.25 metres and also concrete lined, is in its main sinking phase and has reached a depth of approximately 305 metres below surface. Sinking rates in Q1 2017 have been between 45 and 50 metres per month.
Shaft 1 is expected to reach its projected, final depth of 980 metres below surface in 2018. It will be used for underground development of the Flatreef Deposit and ultimately will become the primary ventilation intake shaft during the project’s four-million-tonne-per-annum (Mtpa) initial production case. Shaft stations to provide access to horizontal mine workings for personnel, materials and services will be developed at depths of 750, 850 and 950 metres below surface.
The selected Flatreef mining areas occur at depths ranging from approximately 700 to 1,200 metres below the surface. The planned mining of the Flatreef Deposit will incorporate low-cost, mechanized mining methods, including long-hole stoping and drift-and-fill mining. Mined-out areas are to be backfilled with a mixture of tailings from the processing plant and cement. The ore will be hauled from the mining stopes to a series of ore passes that will connect to a main haulage level leading to a primary rock crusher near Shaft 2, from where it will be hoisted to the surface for processing.

Feasibility study expected to be released in Q2 2017
The definitive feasibility study for Platreef’s first-phase, four Mtpa production scenario is expected to be completed and released in Q2 2017. The study, which began in August 2015, is being prepared by principal consultant DRA Global, with specialized sub-consultants including Stantec Consulting, Murray & Roberts Cementation, SRK Consulting, Golder Associates and Digby Wells Environmental.
The feasibility study will further refine and upgrade the findings of the Platreef January 2015 pre-feasibility study that covered the first phase of development, which includes construction of a highly-mechanized underground mine, concentrator and other associated infrastructure to support initial, estimated concentrate production of 433,000 ounces of platinum-group metals per year.
Ivanplats plans to develop the Platreef Mine as an underground mining operation in three phases: 1) an initial annual rate of four Mtpa to establish an operating platform to support future expansions; 2) a doubling of production to eight Mtpa; and 3) another expansion phase to a steady-state 12 Mtpa. At a projected production rate of 12 Mtpa, Platreef would be the largest platinum-group metals mine in the world, producing more than 1.2 million ounces of platinum-group metals per annum.
The development scenarios describe a staged approach structured to provide opportunities to expand the operation based on demand, smelting and refining capacity and capital availability. As the first phase of development is placed into production, there is expected to be an opportunity to modify and optimize the subsequent phases, allowing for changes to the timing of capacity expansions to suit market conditions.
