Kolwezi, Democratic Republic of Congo - February 24, 2020 (Newsfile Corp.) (Investorideas.com Newswire) Ivanhoe Mines (TSX: IVN) (OTCQX: IVPAF) Co-Chairs Robert Friedland and Yufeng "Miles" Sun announced today that underground development at the Kakula Copper Mine continues to advance ahead of schedule and that more than eight kilometres of underground development now is completed, which is 1.7 kilometres ahead of plan. This month, the mining team is on pace to set a new monthly development record of 1,310 metres of advancement - 380 metres ahead of plan for the month.
The underground development work at Kakula is being performed by mining crews operating large-capacity, semi-autonomous mining equipment, such as jumbo drilling rigs and 50-tonne trucks.
Mine access drives 1 and 2 − interconnected, parallel tunnels being developed from Kakula's main northern declines that will provide access to Kakula's high-grade ore zones − continue to make excellent progress. The two south perimeter drives - being developed from Kakula southern decline - also are progressing ahead of schedule and have each been advanced more than 250 metres from the bottom of the decline.
The development ore is being transported to surface and stored on pre-production stockpiles, which are expected to grow to approximately 1.5 million tonnes of high-grade ore and an additional 700,000 tonnes of material grading approximately 1% to 3% copper prior to the start of initial production in Q3 2021.
Based on the results of the February 2019 Kakula pre-feasibility study, Kakula's average feed grade over the first five years of operations is projected to be 6.8% copper, and 5.5% copper on average over a 25-year mine life.
In parallel with the construction of Kamoa-Kakula's phase 1 Kakula Mine, work is progressing on the independent Kakula definitive feasibility study (DFS) and an updated Integrated Development Plan for the entire Kamoa-Kakula mining complex, which is expected to be issued in mid-2020. The Kakula DFS will provide an increased level of accuracy for the project economics for the initial phase of mine development at Kakula. The Integrated Development Plan will include details on the planned expansion phases for the greater Kamoa-Kakula mining complex, incorporating updates for mineral resources, production rates and economic analysis.

Construction progress on the processing plant and other surface infrastructure remains on track for initial production in Q3 2021
Kakula's original 3.0 million-tonne-per-annum (Mtpa) first processing plant module has already been redesigned during the basic engineering phase to a nameplate capacity of 3.8 Mtpa. Purchase orders have been placed for all major long-lead time mechanical equipment, plant earthworks is complete, and plant civil works are advancing rapidly. The contract for the SMPP (structural, mechanical, piping and platework) supply and erection portion of the plant construction has been awarded and steel fabrication is underway. The capital cost estimate related to the construction of the mining infrastructure (underground and surface), processing plant and surface infrastructure has been estimated to a basic engineering level of accuracy and is being used as the control budget estimate for the project.
The first oversized loads of equipment for Kakula's initial 3.8 Mtpa processing plant module being transported from Kolwezi to Kamoa-Kakula on the newly constructed road. The equipment, which has been delivered to site, is two low-entrainment flotation cells (Jameson cells) that will be used as cleaner cells to produce a final copper concentrate, before thickening and filtration. This is the first of at least 25 oversized loads of equipment that are scheduled to be delivered to Kamoa-Kakula in the coming months.
The current updated estimate of the project's initial capital costs is approximately US$1.3 billion as of January 1, 2019, which assumes commissioning of the first processing plant module in Q3 2021 and includes expanded plant capacity and pre-production ore stockpiles.
Other engineering and construction activities underway at Kamoa-Kakula include the refurbishment of six turbines at the Mwadingusha hydro-electric power plant and associated 220-kilovolt infrastructure to supply the mine with clean hydro-power, finishing construction of a permanent road between the mine site and the Kolwezi airport, construction of the first phase of accommodations for 1,000 employees and contractors, and other surface infrastructure.
More than 4,400 employees and contractors currently are helping to construct the new Kakula Mine, of which approximately 90% are Congolese nationals.
"We're not just investing in a new mine, roads, hydro-power plants, power lines and other important infrastructure, we're investing in good-paying jobs and new opportunities for people who live in the DRC. And with our focus on skills training and apprenticeships for young Congolese, we're helping build the DRC's next generation of skilled tradespeople," said Mark Farren, Chief Executive Officer, Kamoa Copper SA.
Excellent progress is being made on the high-volume conveyor system that will transport broken ore from underground to the surface processing plant. The conveyor system is expected to be fully operational in April 2020.

Kamoa-Kakula focused on producing "green copper"
Together with its joint-venture partners, Ivanhoe is committed to building modern, safe, mechanized mines that will be showcases for responsible, "green" mine development.
"These vast Kamoa and Kakula discoveries are the type of world-scale mineral systems needed to supply the copper for the electrification of the global economy, to usher in the era of the electric car, and the electric everything, in order to reduce our planet's consumption of hydrocarbons," Mr. Friedland said.
"In a world deeply concerned with the unabated generation of global warming gases throughout the supply chain, many people of influence in the world's financial community are becoming aware of the undeniable fact that Copper is the Greenest of the green metals," he added. "Given the challenges of global environmental priorities, and the trend of urbanization that emerging economies throughout Africa share with many nations, copper is definitely the most important metal of our time."
Kamoa-Kakula is unique as it combines ultra-high copper grades in thick, shallow and relatively flat-lying deposits - allowing for large-scale, highly-productive, mechanized underground mining operation. The ultra-high copper grades and underground mines mean that Kamoa-Kakula will have a small surface footprint and will use a fraction of the power, water and consumables - and produce far less tailings - than any comparable large, low-grade, open-pit porphyry copper mine currently in operation elsewhere in the world.
Ivanhoe Mines is committed to tailings management that meets or exceeds global best practices for safety during all phases of the mine lifecycle. For example, approximately 55% of the Kakula's tailings will be mixed with cement and pumped back underground to fill voids and help support the underground mine. The remaining 45% of the tailings will be pumped to a tailings storage facility.
Clean, sustainable hydro-electric power for Kamoa-Kakula
Ivanhoe also is committed to powering its mines with clean, sustainable hydro-electricity. Ongoing upgrading work at the Mwadingusha hydro-power plant in the DRC has significantly progressed with major equipment being delivered to site. The progressive re-commissioning of the turbines, fully refurbished and modernized with state-of-the-art control and instrumentation, is underway and is expected to be completed in Q3 2020. The refurbished plant is projected to deliver approximately 72 megawatts (MW) of power to the national power grid.
The work at Mwadingusha is being conducted by engineering firm Stucky of Lausanne, Switzerland, under the direction of Ivanhoe Mines and Zijin Mining, in conjunction with the DRC's state-owned power company, La Société Nationale d'Electricité (SNEL).
"Hydropower, with its virtues of being clean and renewable, is the best energy solution to support our development priorities as we continue to look for ways to reduce our impact on the environment and produce the copper our world requires," added Mr. Friedland.

Mine development options at Kamoa North being considered
Earlier this month, Ivanhoe issued an updated independently verified Indicated Mineral Resource that increased the combined Kamoa-Kakula Project Indicated Mineral Resource to 423 million tonnes grading 4.68% copper, at a 3% cut-off. At a lower cut-off of 1%, the combined Kamoa-Kakula Project Indicated Mineral Resource now stands at 1.4 billion tonnes grading 2.7% copper.
The entire Kamoa Deposit was updated in the new Mineral Resource estimate. The majority of recent drilling, however, targeted the ultra-high-grade Bonanza Zone at Kamoa North, and an approximated north-south corridor of elevated copper grades in the far north of the mining licence area (the Far North Zone).
The new Kamoa Mineral Resource estimate covers approximately 600 metres of strike length in the deeper western portions of the Bonanza Zone (west of the West Scarp Fault), and 1,500 metres of strike length in the shallower eastern portions of the Bonanza Zone, defined by drill sections spaced 50 metres apart on strike in the central section, and 100 metres apart on strike elsewhere.
The new resource estimate includes the initial Indicated Mineral Resource estimate for the Kamoa North Bonanza Zone, which includes 1.5 million tonnes grading 10.7% copper, at a 5% cut-off. The Bonanza Zone combined with the Kamoa Far North Zone provide an Indicated Mineral Resource of 12 million tonnes at a copper grade of 4.65%, at a 3% cut-off.
Given the shallow depth, remarkable thickness and massive copper sulphide mineralization discovered within the Kamoa North Bonanza Zone, Kamoa-Kakula's engineers are evaluating potential options to accelerate the development of this new discovery.
Geotechnical and hydrogeological drilling to provide support for future mining studies has been completed and mine planning is underway. A number of metallurgical composites also have been generated for existing coarse reject material that will be used for flotation test work.
Drilling continues to target additional resources in the vicinity of the ultra-high-grade Bonanza Zone and the Far North Zone. Several geophysical studies such as ground gravity, ground magnetics and airborne have been conducted in the Kamoa North area to better understand the controls of the ultra-high-grade mineralization and assist in locating additional targets.
The Kamoa-Kakula Copper Project is a joint venture between Ivanhoe Mines (39.6%), Zijin Mining Group (39.6%), Crystal River Global Limited (0.8%) and the DRC government (20%).
