KOLWEZI, DEMOCRATIC REPUBLIC OF CONGO – Ivanhoe Mines (TSX: IVN; OTCQX: IVPAF) Co-Chairs Robert Friedland and Yufeng “Miles” Sun are pleased to announce that underground development at the Kamoa-Kakula Copper Project in the Democratic Republic of Congo (DRC) mined and stockpiled 300,000 tonnes of ore grading 5.45% copper from the Kakula and Kansoko mines in January. The tonnage was 11.5% higher than December, while the copper grade was 1.6% higher.
The 300,000 tonnes mined in January included 231,000 tonnes at an average grade of 6.20% copper, including 82,000 tonnes grading 8.80% copper from the high-grade centre of the Kakula Mine.
The project’s pre-production surface stockpiles now contain approximately 1.82 million tonnes of high-grade and medium-grade ore at an estimated blended grade of 4.23% copper. Contained copper in the stockpiles increased by approximately 16,000 tonnes in January – a 25.9% increase over December’s production reflecting increased mining activity in the ultra-high-grade centre of the Kakula Deposit – to a cumulative total of more than 76,000 tonnes (the current copper price is approximately US$7,940 a tonne).
Kamoa-Kakula is on track to have approximately three million tonnes of high-grade and medium-grade ore stockpiled on surface, holding more than 125,000 tonnes of contained copper, prior to the planned start of processing in July 2021.
“In the mining business, grade is king,” said Mr. Friedland. “And the remarkable grade of the ore coming from Kakula is unprecedented for a major mechanized copper mine of this scale. We are just five months away from scheduled first production, which will mark the next step in the evolution of Ivanhoe Mines into a leading, diversified mining company with a development and exploration portfolio of high-value, critical green metals.”
Mr. Friedland and Mr. Sun also congratulated the project team for establishing yet another new monthly record for underground mine development in January with a total of 2,869 metres of advancement.
“A very strong operational and safety performance by our mining teams in January, and overall a terrific start to 2021,” said Mr. Friedland. “We are immensely proud of the more than 6,000 colleagues on site who are delivering this exceptional project on time and on budget. As we rapidly approach initial production, the project is busy recruiting and training the team that will operate the brand new concentrator plant, creating hundreds of additional permanent, well-paying jobs for local Congolese women and men.”
Underground mine development remains well ahead of schedule, providing the confidence to push forward with Kamoa-Kakula’s Phase 2 construction
January’s record-setting advancement brings total underground development to approximately 32.7 kilometres – around 11.6 kilometres ahead of schedule. The monthly underground development in January was comprised of 2,544 metres at the Kakula Mine and 325 metres at the Kansoko Mine.
Drift-and-fill stoping operations recently commenced at the Kakula Mine, with more than 66% of January’s ore production coming from stoping operations and the remaining coming from mine development activities. Stoping is a highly-productive mining method of extracting underground ore, leaving behind an open space known as a stope.
Mark Farren, Kamoa Copper’s CEO, commented: “The achievement of 300,000 tonnes mined in January is significant as Kamoa-Kakula is fast approaching the mining rate needed to sustain the project’s Phase 1 concentrator plant.”
“It will be important to balance mining volumes and surface stockpiles to meet the requirements of both the Phase 1 and Phase 2 concentrators. We now have nearly two million tonnes of medium- and high-grade ore on surface stockpiles, which should grow to approximately three million tonnes ahead of the scheduled start-up of the concentrator in July, significantly minimizing the ramp-up risk as well as streamlining the commissioning phase,” he continued.
“The large surface ore stockpiles will allow Kamoa-Kakula to maximize throughput once the Phase 1 concentrator is commissioned. Based on our projected mining rates over the next year and a half, we are confident that we also will have more than sufficient stockpiles ahead of the Phase 2 concentrator commissioning,” Mr. Farren added.
Kakula’s combined medium-grade and high-grade ore mined in January was approximately 274,000 tonnes at an average grade of 5.56% copper, including 82,000 tonnes grading 8.80% copper from the +8% copper zone in the centre of the orebody. Mining crews at Kakula are primarily focused on developing the drift-and-fill mining blocks in this high-grade centre. Opening up of the mining footprint for these high grade, drift-and-fill mining areas requires development work in areas of low-, medium- and high-grade ore, and is designed to coincide with the start-up of the processing plant in July. This will allow crews to deliver significant tonnage of high-grade ore directly from Kakula’s underground workings to the processing plant.
Kansoko’s combined medium-grade and high-grade ore mined in January was approximately 26,000 tonnes at an average grade of 4.31% copper. Kansoko’s ore grade increased by 73% in January, compared to December. Kansoko is being developed by training crews and will be a supplemental source of ore for Phase 2 of the project’s development when the Kakula concentrator processing capacity doubles to 7.6 million tonnes per annum (Mtpa) - currently planned to be commissioned in Q3 2022.

Phase 1 copper production from the Kakula Mine is scheduled to begin in July 2021. Kakula is projected to be the world’s highest-grade major copper mine, with an initial mining rate of 3.8 Mtpa at an estimated average feed grade of more than 6.0% copper at first, ramping up to 7.6 Mtpa in Q3 2020. Phases 1 and 2 combined are forecast to produce approximately 400,000 tonnes of copper per year. Based on independent benchmarking, the project’s phased expansion scenario to 19 Mtpa would position Kamoa-Kakula as the world’s second largest copper mining complex, with peak annual copper production of more than 800,000 tonnes.
A 2020 independent audit of Kamoa-Kakula's greenhouse gas intensity metrics performed by Hatch Ltd. of Mississauga, Canada, confirmed that the project will be among the world's lowest greenhouse gas emitters per unit of copper produced.
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 Government of the Democratic Republic of Congo (20%).
January’s ore production was 11.5% higher than December, with monthly copper grade increasing from 5.36% to 5.45%; pre-production surface ore stockpiles now total approximately 1.82 million tonnes grading 4.23% copper

Civil works for the first concentrator plant effectively is complete and the civil contractor now is focusing on the Phase 2 concentrator plant, the high-pressure-grinding-rolls (HPGR) stockpile and milling areas.
Delivery of equipment for the first concentrator plant is nearing completion with more than 2,260 truckloads of equipment – including all structural steel, platework, piping and electrical cable – now on site. The sand filter plant and the last shipments of switchgear are scheduled to arrive in February and March 2021, respectively.
Structural steel erection and platework installation for the first concentrator plant is nearing completion, with only 172 tonnes of structural steel still to be erected (of a total of 4,882 tonnes) and 121 tonnes of platework (of a total of 863 tonnes). Mechanical installation is 68% complete. Piping fabrication and delivery is complete and installation is nearing 50% completion. A total of 83 kilometres of piping will be installed.
All plant areas for the first concentrator have been handed over to the electrical, control and instrumentation (EC&I) contractor for electrical installation. EC&I installation is the last activity before construction completion and subsequent commissioning. Installation of cable racking is complete in most areas and cable installation is well advanced with more than 105,000 metres of copper cable installed out of a total of 207,000 metres (207 kilometres). The installation of instrumentation has started and the energizing of the concentrator plant with medium-voltage power is scheduled for the end of March 2021.

Steel erection and equipment installation for Kakula’s first phase, backfill paste plant effectively is complete with electrical installation well advanced. The backfill plant is scheduled to be complete well before paste backfill is required for mining operations.
The backfill plant will be used to mix tailings from the processing plant with cement to produce paste backfill. The backfill will be pumped back into the mine and used to help support mined-out areas. Approximately one half of the mine’s tailings will be sent back underground, significantly reducing the surface tailings storage.
Construction of the tailings storage facility is progressing well and is scheduled to be completed well ahead of the required date. Installation of the three tailings lines and the tailings-return water line is nearing completion with 24 kilometres (of a total of 25 kilometres) complete.
Construction of the second 3.8-Mtpa concentrator plant is progressing well with the current focus on earthworks and civils. Civils works on the lower base of the ball mills and the HPGR stockpile is underway with a total of 1,720 cubic metres of concrete already poured (of a Phase 2 total of 14,000 cubic metres). Bulk earthworks is approximately 37% complete. With orders for all the long lead items of equipment for the Phase 2 concentrator placed in September 2020, procurement activities have focused on the remainder of the plant equipment. The contract for structural steel supply has been placed.
Work on the concrete foundations for Kakula’s Phase 2 ball mills is making excellent progress, while construction of Kakula’s Phase 1 ball mills (background) is nearing completion.

Advanced, detailed discussions for the marketing of Kakula’s copper concentrates
Kamoa-Kakula is in advanced, detailed discussions with a number of parties with respect to the sale of its copper concentrates. Kakula is expected to produce an extremely high-grade and clean copper concentrate (containing over 55% copper) that will be highly coveted by copper smelters around the world. Metallurgical test work indicates that the Kakula concentrates contain extremely low arsenic levels by world standards – approximately 0.01%.
Kamoa-Kakula now connected to 220-kV national electrical grid; the first of six turbines at the refurbished Mwadingusha hydropower plant now synchronized to the national electrical grid, providing clean, renewable hydropower
In December 2020, the 35-kilometre-long double circuit 220-kilovolt (kV) power line feeding into Kamoa-Kakula was connected to the national electrical grid through theNew Western Dispatch (NRO) substation in Kolwezi. Kamoa-Kakula’s main 220-kV substation is nearing completion and is expected to be energized by the end of March.

Ivanhoe Mines Energy DRC also announced that the first of six new turbines at the Mwadingusha hydropower plant was synchronized to the national electrical grid in December 2020. The commissioning of the hydropower plant’s remaining five generating units, in sequence, is in progress. This will ensure that Kamoa-Kakula’s power requirements are met ahead of the commissioning of the concentrator plant.
The fully-refurbished Mwadingusha hydropower plant now is expected to deliver approximately 78 megawatts of power to the national electrical grid.
Ivanhoe Mines Energy DRC achieved a significant milestone in December when the first of six turbines at the Mwadingusha hydropower plant began delivering clean, hydropower to the national electrical grid.

COVID-19 prevention initiatives continue to focus on risk mitigation
Kamoa-Kakula’s prevention measures remain strictly enforced, with further prevention being the focus while the world responds to the latest COVID-19 strains. Rigorous testing, physical distancing, wearing of face masks, frequent hand washing and contact-tracing measures still are in place to protect the safety and health of the workforce and community members.
The project has a well-established COVID-19 isolation facility at the Kamoa Camp. Suspected cases and symptomatic patients are moved to this facility, where they are isolated, tested and treated. Once patients have recovered and are deemed no longer infectious, they can return to work only after an additional quarantine period determined by the project’s medical staff.
Kamoa-Kakula has successfully sourced the latest COVID-19 rapid diagnostic tests (RDT) that test for antigens (the presence of viral particles). The tests are being used by the medical team at Kamoa-Kakula to screen all site arrivals and travellers. Test results are received within an average of 20 minutes, which further enhances the preventative measures already in place.
As the pandemic evolves, the medical team at Kamoa-Kakula continues to review and update its risk mitigation protocols. The project’s preventative measures are at the highest international standards, and should there be a case internally, the risk of spreading or cross-contamination is considered to be very low.

Surface stockpiles now contain an estimated 68,000 tonnes of ore grading 5.90% copper and 394,000 tonnes of medium-grade ore grading 2.71% copper, including satellite stockpiles at Kakula South and Kansoko
KOLWEZI, DEMOCRATIC REPUBLIC OF CONGO – 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 exceed expectations with more than 17 kilometres now complete, which is 5.1 kilometres ahead of schedule. In June, the mining team achieved 1,729 metres of underground development – 575 metres ahead of plan for the month.
Kakula’s 2,000-tonne-per-hour ore conveyor system began operations in June, which will further increase the mine’s pace of underground development.
The majority of the development headings at the Kakula Mine currently are traversing medium-grade sections of the orebody, with average grades ranging between 3% and 5% copper. Several development headings are continuing in high-grade zones grading more than 8% copper, and this ore is being placed on a dedicated, high-grade surface stockpile at Kakula North that now totals approximately 68,000 tonnes grading an estimated 5.90% copper. The medium-grade surface stockpiles at Kakula North, Kakula South and Kansoko together contain an additional 394,000 tonnes grading an estimated 2.71% copper.
As Kakula’s underground development progresses over the next few months, the majority of the headings are expected to transition into the high-grade ore zones.
More than 200 truck loads, consisting mainly of structural steel and equipment for Kakula’s initial 3.8-million-tonne-per-annum processing plant, were received on site in June and construction of the plant is progressing rapidly. Fabrication of the plant’s largest components – two ball mills each measuring 9.75 metres (32 feet) long and 6.1 metres (20 feet) in diameter – has been completed at CITIC Heavy Industries’ factory in Luoyang, China, and shipping of the components is underway.
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%).

Kakula’s decline conveyor system that will transport ore from underground to surface now is operational. Final commissioning of the full system (including the fire suppression system and all safety components) is underway and is scheduled to be completed around mid-July. The conveyor system has the capacity to transport 2,000 tonnes of ore per hour from underground to surface.
The conveyor system substantially shortens the haulage distance for the mine’s truck fleet; significantly increasing productivity, and lowering mining and maintenance costs.
Construction of the surface conveyor system has commenced and the first steel has been delivered to site. The surface conveyor system will transport ore from the decline conveyor system to the main processing plant stockpile. Forecast completion date is scheduled for Q1 2021.

Development of the Kakula Mine, the first deposit to be placed into production on the 400-square-kilometre Kamoa-Kakula mining licence, is well ahead of schedule. Mine access drives 1 and 2 (interconnected, parallel tunnels that will provide access to ore zones) continue to progress well towards the southern portion of the orebody.
Development also is well advanced on the eastern perimeter drives and the room-and-pillar mining area. Development from the southern portal has reached south access drives 1 and 2, with mining crews working to establish the connection of these drives with mine access drives 1 and 2 from the north side of the orebody. The northern and southern access drives are scheduled to be joined by the end of October 2020.
Underground mining also is occurring at the Kansoko Mine, located at the Kamoa deposit approximately 10 kilometres north of the Kakula Mine. Kansoko is development ready and currently is being used to train young Congolese mining crews.
The main surface exhaust ventilation fans (VS#2) are progressing well with fan fabrication on schedule and the ventilation shaft raise boring complete. The NE#1 fan station pilot hole has commenced with fabrication of the fans scheduled to start this month. The third underground water pumping train at Kakula’s main decline pumping chamber has been commissioned, increasing the mine’s pumping capacity to 600 litres per second.
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 finalized this month. 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
Construction of Kamoa’s 3.8-million tonne-per-annum (Mtpa) concentrator plant is progressing well, with more than15,000 cubic metres of concrete being poured to date. Concrete bases for the ball mills, flotation plant and the concentrate thickener have been partially handed over to the mechanical contractor to commence installation work, and steel erection is currently underway in the flotation and thickener areas. Approximately 3,600 tonnes of structural steel had been shipped from China by end of June.
Beijing-based CITIC Construction has been awarded the construction contract for Kakula’s phase 1 backfill paste plant. The backfill plant will be used to blend tailings from the processing plant with cement to produce paste backfill. The backfill will be pumped back into the mine and used to help support mined-out areas. Approximately 55% of the mine’s tailings will be sent back underground, significantly reducing the surface tailings storage.
The Electrical & Instrumentation contract was recently awarded to T3 Construction, a leading South African construction company. This is the final major construction contract required for Kakula’s processing and backfill plants.
Construction of the tailings dam has commenced and is progressing well, the aim is to complete most of the earthworks during the dry season before the rainy season starts in November.

Clean, sustainable hydro-electric power for Kamoa-Kakula
Construction activities at the Mwadingusha hydro-electric power plant, where all six turbines are being replaced, is progressing well; as is the associated 220-kilovolt (kVA) infrastructure to supply the mine with clean hydro-power. The mine is scheduled to be energized with permanent 220kV hydro-generated power in early 2021, well in time for first copper production.
The temporary construction power supply for the Kakula Mine was recently upgraded, including the commissioning of five new 2MW generators to provide back-up power, and the installation of an 18MW/120kV mobile substation to increase the capacity of grid power available at the mine. This will provide sufficient power until the main 220kV power supply is energized.
Construction of the 220kV supply infrastructure is in progress, including: a new 220kV distribution sub-station for the power utility (SNEL); and a new 35-kilometre, 220kV power line and a consumer substation at Kakula with two 80MW/220kV transformers. The transformers are presently being factory tested and prepared for shipment to site.
A new access road from the city of Kolwezi to the Kansoko and Kakula mines was recently completed and is now open to traffic.
Kamoa-Kakula’s COVID-19 readiness initiatives focused on risk mitigation
More than 3,500 employees and contractors currently are working on site, of which approximately 90% are Congolese nationals. To date, Kamoa-Kakula has had no confirmed COVID-19 cases.
As part of Kamoa-Kakula’s COVID-19 readiness initiatives, the project has procured a polymerize chain reaction (PCR) device from German-based Bosch (similar device to the GeneXpert). The device is scheduled to arrive this week, with an initial supply of 500 tests. The device’s capacity is 15 tests per 24-hour period.
PCR tests are used to directly detect the presence of an antigen, rather than the presence of the body’s immune response, or antibodies. By detecting viral RNA, which will be present in the body before antibodies form or symptoms of the disease are present, the tests can tell whether or not someone has the virus very early on.
Early detection of potential cases based on symptoms and contact tracing is imperative. PCR tests will give the project’s medical team a good indication of who is infected. This allows for fast isolation, and contact tracing of potential additional cases for quarantine.
The project has established a COVID-19 isolation facility at the Kamoa camp. Any suspected or symptomatic cases are moved to this facility, where they are isolated, treated and tested. Once the patient has recovered and is deemed no longer infectious, they can return to work only after an additional quarantine period determined by the project’s medical staff.
As the pandemic evolves, the medical team at Kamoa-Kakula is purposefully reviewing and updating its risk mitigation protocols. The project’s preventative measures are at the highest standard and if there was a case internally, the risk of spreading or cross contamination is very low.

Monthly development in June well ahead of plan with 1,729 metres achieved
Kakula’s 2,000-tonne-per-hour ore conveyor system begins operation
All major equipment and the majority of structural steel now on site, or en route, for Kakula’s first phase 3.8-million-tonne-per-annum processing plant scheduled to begin operations in Q3 2021
Surface stockpiles now contain an estimated 68,000 tonnes of ore grading 5.90% copper and 394,000 tonnes of medium-grade ore grading 2.71% copper, including satellite stockpiles at Kakula South and Kansoko
KOLWEZI, DEMOCRATIC REPUBLIC OF CONGO – 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 exceed expectations with more than 17 kilometres now complete, which is 5.1 kilometres ahead of schedule. In June, the mining team achieved 1,729 metres of underground development – 575 metres ahead of plan for the month.
Kakula’s 2,000-tonne-per-hour ore conveyor system began operations in June, which will further increase the mine’s pace of underground development.
The majority of the development headings at the Kakula Mine currently are traversing medium-grade sections of the orebody, with average grades ranging between 3% and 5% copper. Several development headings are continuing in high-grade zones grading more than 8% copper, and this ore is being placed on a dedicated, high-grade surface stockpile at Kakula North that now totals approximately 68,000 tonnes grading an estimated 5.90% copper. The medium-grade surface stockpiles at Kakula North, Kakula South and Kansoko together contain an additional 394,000 tonnes grading an estimated 2.71% copper.
As Kakula’s underground development progresses over the next few months, the majority of the headings are expected to transition into the high-grade ore zones.
More than 200 truck loads, consisting mainly of structural steel and equipment for Kakula’s initial 3.8-million-tonne-per-annum processing plant, were received on site in June and construction of the plant is progressing rapidly. Fabrication of the plant’s largest components – two ball mills each measuring 9.75 metres (32 feet) long and 6.1 metres (20 feet) in diameter – has been completed at CITIC Heavy Industries’ factory in Luoyang, China, and shipping of the components is underway.
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%).

Development of the Kakula Mine, the first deposit to be placed into production on the 400-square-kilometre Kamoa-Kakula mining licence, is well ahead of schedule. Mine access drives 1 and 2 (interconnected, parallel tunnels that will provide access to ore zones) continue to progress well towards the southern portion of the orebody.
Development also is well advanced on the eastern perimeter drives and the room-and-pillar mining area. Development from the southern portal has reached south access drives 1 and 2, with mining crews working to establish the connection of these drives with mine access drives 1 and 2 from the north side of the orebody. The northern and southern access drives are scheduled to be joined by the end of October 2020.
Underground mining also is occurring at the Kansoko Mine, located at the Kamoa deposit approximately 10 kilometres north of the Kakula Mine. Kansoko is development ready and currently is being used to train young Congolese mining crews.
The main surface exhaust ventilation fans (VS#2) are progressing well with fan fabrication on schedule and the ventilation shaft raise boring complete. The NE#1 fan station pilot hole has commenced with fabrication of the fans scheduled to start this month. The third underground water pumping train at Kakula’s main decline pumping chamber has been commissioned, increasing the mine’s pumping capacity to 600 litres per second.
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 finalized this month. 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
Construction of Kamoa’s 3.8-million tonne-per-annum (Mtpa) concentrator plant is progressing well, with more than15,000 cubic metres of concrete being poured to date. Concrete bases for the ball mills, flotation plant and the concentrate thickener have been partially handed over to the mechanical contractor to commence installation work, and steel erection is currently underway in the flotation and thickener areas. Approximately 3,600 tonnes of structural steel had been shipped from China by end of June.
Beijing-based CITIC Construction has been awarded the construction contract for Kakula’s phase 1 backfill paste plant. The backfill plant will be used to blend tailings from the processing plant with cement to produce paste backfill. The backfill will be pumped back into the mine and used to help support mined-out areas. Approximately 55% of the mine’s tailings will be sent back underground, significantly reducing the surface tailings storage.
The Electrical & Instrumentation contract was recently awarded to T3 Construction, a leading South African construction company. This is the final major construction contract required for Kakula’s processing and backfill plants.
Construction of the tailings dam has commenced and is progressing well, the aim is to complete most of the earthworks during the dry season before the rainy season starts in November.

Clean, sustainable hydro-electric power for Kamoa-Kakula
Construction activities at the Mwadingusha hydro-electric power plant, where all six turbines are being replaced, is progressing well; as is the associated 220-kilovolt (kVA) infrastructure to supply the mine with clean hydro-power. The mine is scheduled to be energized with permanent 220kV hydro-generated power in early 2021, well in time for first copper production.
The temporary construction power supply for the Kakula Mine was recently upgraded, including the commissioning of five new 2MW generators to provide back-up power, and the installation of an 18MW/120kV mobile substation to increase the capacity of grid power available at the mine. This will provide sufficient power until the main 220kV power supply is energized.
Construction of the 220kV supply infrastructure is in progress, including: a new 220kV distribution sub-station for the power utility (SNEL); and a new 35-kilometre, 220kV power line and a consumer substation at Kakula with two 80MW/220kV transformers. The transformers are presently being factory tested and prepared for shipment to site.
A new access road from the city of Kolwezi to the Kansoko and Kakula mines was recently completed and is now open to traffic.
Kamoa-Kakula’s COVID-19 readiness initiatives focused on risk mitigation
More than 3,500 employees and contractors currently are working on site, of which approximately 90% are Congolese nationals. To date, Kamoa-Kakula has had no confirmed COVID-19 cases.
As part of Kamoa-Kakula’s COVID-19 readiness initiatives, the project has procured a polymerize chain reaction (PCR) device from German-based Bosch (similar device to the GeneXpert). The device is scheduled to arrive this week, with an initial supply of 500 tests. The device’s capacity is 15 tests per 24-hour period.
PCR tests are used to directly detect the presence of an antigen, rather than the presence of the body’s immune response, or antibodies. By detecting viral RNA, which will be present in the body before antibodies form or symptoms of the disease are present, the tests can tell whether or not someone has the virus very early on.
Early detection of potential cases based on symptoms and contact tracing is imperative. PCR tests will give the project’s medical team a good indication of who is infected. This allows for fast isolation, and contact tracing of potential additional cases for quarantine.
The project has established a COVID-19 isolation facility at the Kamoa camp. Any suspected or symptomatic cases are moved to this facility, where they are isolated, treated and tested. Once the patient has recovered and is deemed no longer infectious, they can return to work only after an additional quarantine period determined by the project’s medical staff.
As the pandemic evolves, the medical team at Kamoa-Kakula is purposefully reviewing and updating its risk mitigation protocols. The project’s preventative measures are at the highest standard and if there was a case internally, the risk of spreading or cross contamination is very low.

Monthly development in June well ahead of plan with 1,729 metres achieved
Kakula’s 2,000-tonne-per-hour ore conveyor system begins operation
All major equipment and the majority of structural steel now on site, or en route, for Kakula’s first phase 3.8-million-tonne-per-annum processing plant scheduled to begin operations in Q3 2021
Surface stockpiles now contain an estimated 68,000 tonnes of ore grading 5.90% copper and 394,000 tonnes of medium-grade ore grading 2.71% copper, including satellite stockpiles at Kakula South and Kansoko
KOLWEZI, DEMOCRATIC REPUBLIC OF CONGO – 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 exceed expectations with more than 17 kilometres now complete, which is 5.1 kilometres ahead of schedule. In June, the mining team achieved 1,729 metres of underground development – 575 metres ahead of plan for the month.
Kakula’s 2,000-tonne-per-hour ore conveyor system began operations in June, which will further increase the mine’s pace of underground development.
The majority of the development headings at the Kakula Mine currently are traversing medium-grade sections of the orebody, with average grades ranging between 3% and 5% copper. Several development headings are continuing in high-grade zones grading more than 8% copper, and this ore is being placed on a dedicated, high-grade surface stockpile at Kakula North that now totals approximately 68,000 tonnes grading an estimated 5.90% copper. The medium-grade surface stockpiles at Kakula North, Kakula South and Kansoko together contain an additional 394,000 tonnes grading an estimated 2.71% copper.
As Kakula’s underground development progresses over the next few months, the majority of the headings are expected to transition into the high-grade ore zones.
More than 200 truck loads, consisting mainly of structural steel and equipment for Kakula’s initial 3.8-million-tonne-per-annum processing plant, were received on site in June and construction of the plant is progressing rapidly. Fabrication of the plant’s largest components – two ball mills each measuring 9.75 metres (32 feet) long and 6.1 metres (20 feet) in diameter – has been completed at CITIC Heavy Industries’ factory in Luoyang, China, and shipping of the components is underway.
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%).

Kakula’s high-capacity ore conveyor system begins operation
Kakula’s decline conveyor system that will transport ore from underground to surface now is operational. Final commissioning of the full system (including the fire suppression system and all safety components) is underway and is scheduled to be completed around mid-July. The conveyor system has the capacity to transport 2,000 tonnes of ore per hour from underground to surface.
The conveyor system substantially shortens the haulage distance for the mine’s truck fleet; significantly increasing productivity, and lowering mining and maintenance costs.
Construction of the surface conveyor system has commenced and the first steel has been delivered to site. The surface conveyor system will transport ore from the decline conveyor system to the main processing plant stockpile. Forecast completion date is scheduled for Q1 2021.

Development of the Kakula Mine, the first deposit to be placed into production on the 400-square-kilometre Kamoa-Kakula mining licence, is well ahead of schedule. Mine access drives 1 and 2 (interconnected, parallel tunnels that will provide access to ore zones) continue to progress well towards the southern portion of the orebody.
Development also is well advanced on the eastern perimeter drives and the room-and-pillar mining area. Development from the southern portal has reached south access drives 1 and 2, with mining crews working to establish the connection of these drives with mine access drives 1 and 2 from the north side of the orebody. The northern and southern access drives are scheduled to be joined by the end of October 2020.
Underground mining also is occurring at the Kansoko Mine, located at the Kamoa deposit approximately 10 kilometres north of the Kakula Mine. Kansoko is development ready and currently is being used to train young Congolese mining crews.
The main surface exhaust ventilation fans (VS#2) are progressing well with fan fabrication on schedule and the ventilation shaft raise boring complete. The NE#1 fan station pilot hole has commenced with fabrication of the fans scheduled to start this month. The third underground water pumping train at Kakula’s main decline pumping chamber has been commissioned, increasing the mine’s pumping capacity to 600 litres per second.
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 finalized this month. 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
Construction of Kamoa’s 3.8-million tonne-per-annum (Mtpa) concentrator plant is progressing well, with more than15,000 cubic metres of concrete being poured to date. Concrete bases for the ball mills, flotation plant and the concentrate thickener have been partially handed over to the mechanical contractor to commence installation work, and steel erection is currently underway in the flotation and thickener areas. Approximately 3,600 tonnes of structural steel had been shipped from China by end of June.
Beijing-based CITIC Construction has been awarded the construction contract for Kakula’s phase 1 backfill paste plant. The backfill plant will be used to blend tailings from the processing plant with cement to produce paste backfill. The backfill will be pumped back into the mine and used to help support mined-out areas. Approximately 55% of the mine’s tailings will be sent back underground, significantly reducing the surface tailings storage.
The Electrical & Instrumentation contract was recently awarded to T3 Construction, a leading South African construction company. This is the final major construction contract required for Kakula’s processing and backfill plants.
Construction of the tailings dam has commenced and is progressing well, the aim is to complete most of the earthworks during the dry season before the rainy season starts in November.

Clean, sustainable hydro-electric power for Kamoa-Kakula
Construction activities at the Mwadingusha hydro-electric power plant, where all six turbines are being replaced, is progressing well; as is the associated 220-kilovolt (kVA) infrastructure to supply the mine with clean hydro-power. The mine is scheduled to be energized with permanent 220kV hydro-generated power in early 2021, well in time for first copper production.
The temporary construction power supply for the Kakula Mine was recently upgraded, including the commissioning of five new 2MW generators to provide back-up power, and the installation of an 18MW/120kV mobile substation to increase the capacity of grid power available at the mine. This will provide sufficient power until the main 220kV power supply is energized.
Construction of the 220kV supply infrastructure is in progress, including: a new 220kV distribution sub-station for the power utility (SNEL); and a new 35-kilometre, 220kV power line and a consumer substation at Kakula with two 80MW/220kV transformers. The transformers are presently being factory tested and prepared for shipment to site.
A new access road from the city of Kolwezi to the Kansoko and Kakula mines was recently completed and is now open to traffic.
Kamoa-Kakula’s COVID-19 readiness initiatives focused on risk mitigation
More than 3,500 employees and contractors currently are working on site, of which approximately 90% are Congolese nationals. To date, Kamoa-Kakula has had no confirmed COVID-19 cases.
As part of Kamoa-Kakula’s COVID-19 readiness initiatives, the project has procured a polymerize chain reaction (PCR) device from German-based Bosch (similar device to the GeneXpert). The device is scheduled to arrive this week, with an initial supply of 500 tests. The device’s capacity is 15 tests per 24-hour period.
PCR tests are used to directly detect the presence of an antigen, rather than the presence of the body’s immune response, or antibodies. By detecting viral RNA, which will be present in the body before antibodies form or symptoms of the disease are present, the tests can tell whether or not someone has the virus very early on.
Early detection of potential cases based on symptoms and contact tracing is imperative. PCR tests will give the project’s medical team a good indication of who is infected. This allows for fast isolation, and contact tracing of potential additional cases for quarantine.
The project has established a COVID-19 isolation facility at the Kamoa camp. Any suspected or symptomatic cases are moved to this facility, where they are isolated, treated and tested. Once the patient has recovered and is deemed no longer infectious, they can return to work only after an additional quarantine period determined by the project’s medical staff.
As the pandemic evolves, the medical team at Kamoa-Kakula is purposefully reviewing and updating its risk mitigation protocols. The project’s preventative measures are at the highest standard and if there was a case internally, the risk of spreading or cross contamination is very low.
