The Morenci mine is a porphyry copper deposit that has oxide, secondary sulfide mineralization, and primary sulfide mineralization. The predominant oxide copper mineral is chrysocolla. Chalcocite is the most important secondary copper sulfide mineral and chalcopyrite the dominant primary copper sulfide

The Morenci operation consists of two concentrators capable of milling 115,000 metric tons of ore per day (mtd), which produce copper and molybdenum concentrate; a 68,000 mtd, crushed-ore leach pad and stacking system; a low-grade run-of-mine (ROM) leaching system; four SX plants; and three EW tank houses that produce copper cathode. Total EW tank house capacity is approximately 900 million pounds of copper per year. Morenci’s available mining fleet consists of one hundred and twenty-six 236-metric ton haul trucks loaded by 13 shovels with bucket sizes ranging from 47 to 57 cubic meters, which are capable of moving an average of 815,000 metric tons of material per day

Phelps Dodge & Company invested $50,000 in the property in 1881, marking the New York mercantile’s first venture into mining. Through acquisition, Phelps Dodge & Company consolidated all mining operations in the district by 1921

Initially underground, Morenci transitioned to open-pit mining beginning in 1937. The operation nearly doubled its production capacity during World War II at the urging of the U.S. government to meet wartime needs. Morenci’s first SX/EW plant was commissioned in 1987. Once home to two smelters, the last smelter ceased operation in 1984. Both have been demolished and reclaimed

72% - Freeport-McMoRan Inc. (undivided interest); 15% - Sumitomo Metal Mining Arizona Inc. (SMMAz is owned 80% by Sumitomo Metal Mining Co. Ltd. (SMM) and 20% by Sumitomo Corporation); and 13% - SMM Morenci Inc. (fully owned by SMM)

Bagdad is home to the world’s first commercial-scale concentrate leach processing facility (2003) and one of the longest continuously operating solution extraction/electrowinning (SX/EW) plants in the world (1970). An unincorporated community, Bagdad is one of two FCX “company towns;” the other is Morenci, Arizona

north america | freeport-mcmoran

The Bagdad mine is a porphyry copper deposit containing both sulfide and oxide mineralization. Chalcopyrite and molybdenite are the dominant primary sulfides and are the primary economic minerals in the mine. Chalcocite is the most common secondary copper sulfide mineral and the predominant oxide copper minerals are chrysocolla, malachite and azurite

The Bagdad operation consists of a 75,000 metric ton-per-day concentrator that produces copper and molybdenum concentrate, an SX/EW plant that can produce up to 32 million pounds per year of copper cathode from solution generated by low-grade stockpile leaching, and a pressure-leach plant to process molybdenum concentrate

First claims staked in 1882. Property changed ownership numerous times through first half of 20th century. First mill began operation in 1928 to process ore from the underground mine. Transition to open-pit mining began in 1945. A $240 million expansion in 1973 included new haul trucks, shovels, nearly 400 housing units and concentrator

north america | freeport-mcmoran

The Sierrita mine is a porphyry copper deposit that has oxide and secondary sulfide mineralization, and primary sulfide mineralization. The predominant oxide copper minerals are malachite, azurite and chrysocolla. Chalcocite is the most important secondary copper sulfide mineral, and chalcopyrite and molybdenite are the dominant primary sulfides

The Sierrita operation includes a 100,000 metric ton-per-day concentrator that produces copper and molybdenum concentrate. Sierrita also produces copper from a ROM oxide-leaching system. Cathode copper is plated at the Twin Buttes EW facility, which has a design capacity of approximately 50 million pounds of copper per year. The Sierrita operation also has molybdenum facilities consisting of a leaching circuit, two molybdenum roasters and a packaging facility. The molybdenum facilities process molybdenum concentrate produced by Sierrita, from our other mines and from third-party sources

First claims recorded in 1895. First worked as an underground mine beginning in 1907; open-pit development began in 1957. In 2009, FCX purchased the Twin Buttes copper mine, which ceased operations in 1994 and is adjacent to the Sierrita mine. The purchase provides significant synergies in the Sierrita minerals district, including the potential for expanded mining activities and access to material that can be used for Sierrita tailings and stockpile reclamation purposes

north america | freeport-mcmoran

The Miami mine is a porphyry copper deposit that has leachable oxide and secondary sulfide mineralization. The predominant oxide copper minerals are chrysocolla, copper-bearing clays, malachite and azurite. Chalcocite and covellite are the most important secondary copper sulfide minerals

Since about 1915, the Miami mining operation had processed copper ore using both flotation and leaching technologies. The design capacity of the SX/EW plant is 200 million pounds of copper per year. Miami is no longer mining ore, but currently produces copper through leaching material already placed on stockpiles, which is expected to continue until 2023

The first prospecting expeditions visited the area in the 1860s. Copper was mined underground until after World War II, when the first open-pit mining began. Miami was among the first to employ “vat leaching” (1926) and precipitation plants to recover oxide minerals. It did this in conjunction with its flotation concentrator, which processed sulfide minerals. The plant’s smelter was modernized in 1974 to meet Clean Air Act standards and further modernized and expanded in 1992. The success of an SX/EW plant commissioned in 1979 led to the demise of vat leaching by the mid-1980s and ultimately the concentrator in 1986. The rod mill was commissioned in 1966 and the refinery in 1993 (the refinery was permanently closed in 2005)

north america | freeport-mcmoran

The Miami smelter processes copper concentrate primarily from FCX’s Arizona copper mines. In addition, because sulphuric acid is a by-product of smelting concentrates, the Miami smelter is also the most significant source of sulphuric acid for FCX’s North America leaching operations. Miami is the only smelter in the United States to achieve International Organization for Standardization (ISO) 9001:2000 certification. In addition to copper concentrates, the smelter also recycles inorganic metal-bearing waste typically produced by high technology industries, extending the useful life of valuable metals and reducing disposal of metal-bearing waste in landfills. Copper and other precious metals are extracted during this process

The Safford mine includes two copper deposits that have oxide mineralization overlaying primary copper sulfide mineralization. The predominant oxide copper minerals are chrysocolla and copper-bearing iron oxides with the predominant copper sulfide material being chalcopyrite

The property is a mine-for-leach project and produces copper cathode. The operation consists of two open pits feeding a crushing facility with a capacity of 103,000 metric tons per day. The crushed ore is delivered to leach pads by a series of overland and portable conveyors. Leach solutions feed a SX/EW facility with a capacity of 240 million pounds of copper per year. A sulfur burner plant is also in operation at Safford, providing a cost-effective source of sulphuric acid used in SX/EW operations

The historic Chino mine was among the first low-grade, open-pit copper mines in the world. During 2011, mining and milling activities were restarted at the Chino mine. In April 2020, operations at Chino were suspended to address COVID-19 concerns. A review of options for restarting Chino operations was completed in the second half of 2020. In January 2021, FCX restarted mining activities at the Chino mine at a reduced rate of approximately 100 million pounds of copper per year.

The Chino mine is a porphyry copper deposit with adjacent copper skarn deposits. There is leachable oxide, secondary sulfide and millable primary sulfide mineralization. The predominant oxide copper mineral is chrysocolla. Chalcocite is the most important secondary copper sulfide mineral, and chalcopyrite and molybdenite the dominant primary sulfides

The Chino operation consists of a 36,000 metric ton-per-day concentrator that produces copper and molybdenum concentrate, and a 150 million pound-per-year SX/EW plant that produces copper cathode from solution generated by ROM leaching. The available mining fleet consists of thirty-five 240-metric ton haul trucks loaded by four shovels with bucket sizes ranging from 31 to 48 cubic meters, which are capable of moving an average of 235,000 metric tons of material per day

Originally mined by Native Americans and later by Spaniards. The open-pit mine began production in 1910. The original concentrator went into operation in 1911, but was replaced by a new facility in 1982. A smelter was commissioned in 1939 and was modernized in 1985 to increase capacity and achieve compliance with the Clean Air Act. In 2005, the smelter was permanently closed

Prior to 1860, Native Americans mined turquoise at the site. Freeport-McMoRan Corporation (formerly Phelps Dodge Corporation) acquired mining claims in the area from 1909 to 1916, and began concentrating ore produced from large-scale underground mining in 1916. Operations ended in 1921. The property returned to operation as an open pit in 1967, with copper production from a concentrator. The SX/EW facility was commissioned in 1984. Tyrone’s concentrator suspended operations in 1992 when the property made the transition to SX/EW production

The Henderson mill site is located 15 miles west of the mine. The mine and the mill are connected by the world's largest conveyor of its kind: a 10-mile conveyor tunnel under the Continental Divide and an additional five-mile surface conveyor

north america | freeport-mcmoran

The Henderson operation consists of a large block-cave underground mining complex feeding a concentrator with a current capacity of approximately 32,000 metric tons per day. Henderson has the capacity to produce approximately 35 million pounds of molybdenum per year. In response to market conditions, the Henderson molybdenum mine has operated at reduced rates since 2015

In North America, FCX operates seven open-pit copper mines — Morenci, Bagdad, Safford, Sierrita and Miami in Arizona, and Chino and Tyrone in New Mexico; and two molybdenum mines — Henderson and Climax in Colorado. Molybdenum concentrate, gold and silver are also produced by certain of FCX’s North America copper mines

FCX’s Lone Star project located near its Safford operation in Arizona is substantially complete and on track to produce approximately 200 million pounds of copper per year beginning in the second half of 2020

north america | freeport-mcmoran

FCX has significant undeveloped reserves and resources in North America and a portfolio of potential long-term development projects. Future investments are dependent on market conditions and will be undertaken based on the results of economic and technical feasibility studies, including the incorporation of innovation initiatives to reduce capital intensity

kamoa-kakulacopperprojectminesand stockpiles 269,000

Kolwezi, Democratic Republic of Congo--(Newsfile Corp. - January 5, 2021) - 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 269,000 tonnes of ore grading 5.36% copper in December from the Kakula and Kansoko mines. The tonnage was 7.6% higher than November, while the copper grade was 10.5% higher

The project's pre-production surface stockpiles now contain approximately 1.52 million tonnes of high-grade and medium-grade ore at an estimated blended grade of 4.03% copper. Contained copper in the stockpiles increased by approximately 14,400 tonnes in December - a 30.9% increase over November's production reflecting the increased mining in the ultra-high-grade centre of the Kakula Deposit - to a cumulative total of more than 61,000 tonnes (the current copper price is approximately US$7,900 a tonne)

The project 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

kamoa-kakulacopperprojectminesand stockpiles 269,000

Mr. Friedland and Mr. Sun also noted that the project team established another new monthly record for underground mine development in December with a total of 2,792 metres of advancement - 620 metres more than the previous monthly high achieved in October 2020. Another important development milestone was achieved in late December with the second holing of Kakula's northern and southern access tunnels, establishing additional access to mine Kakula's high-grade ore in the centre of the orebody grading +8% copper

"After more than 26 years of continuous efforts, Ivanhoe Mines and its joint-venture partners are less than six months away from initial production at Kamoa-Kakula - the first world-scale copper discovery on the African continent in generations. This year's transformation marks the beginning of the next chapter of our journey that began in 1994 and has involved thousands of dedicated and talented people," said Mr. Friedland. "Underground development at the Kakula Mine is well ahead of schedule and construction of the first phase processing plant is on schedule to produce exceptionally high-grade and clean copper concentrates beginning this July. The performance of Kamoa Copper's multinational management team in successfully navigating the profound logistical challenges posed by the global COVID-19 pandemic has been absolutely outstanding."

"Our expectations are for continued rising copper prices through 2021 and beyond; as such, the timing of Kamoa Copper's first production is fortuitous given that the project is scheduled to have ore stockpiles containing more than 125,000 tonnes of contained copper available for processing by July 1st. A rising copper price directly impacts the realizable value of the contained copper in the stockpiles, the cost of which is capitalized," Mr. Friedland added

kamoa-kakulacopperprojectminesand stockpiles 269,000

December's record-setting advancement brings total underground development to approximately 29.8 kilometres - approximately 10.5 kilometres ahead of schedule. The monthly underground development in December was comprised of 2,521 metres at the Kakula Mine and 271 metres at the Kansoko Mine

Mark Farren, Kamoa Copper's CEO, commented: "A terrific performance by our mining teams in December and an exceptional way to end 2020. To achieve a record-setting month in the midst of the holiday season is a testament to the commitment and professionalism of our people. The start of 2021 brings with it a sense of excitement and opportunity as we begin to shift our focus from mine development to production."

"Mining crews recently entered a remarkably thick zone of high-grade ore grading +8% copper in the centre of the Kakula Mine, which has allowed us to enlarge the development drifts in this area to 10 metres high by 7.5 metres wide (75 square metres), and the increase in ore tonnes per metre of development has been substantial," Mr. Farren added

kamoa-kakulacopperprojectminesand stockpiles 269,000

Kakula's combined medium-grade and high-grade ore mined in December was approximately 245,000 tonnes at an average grade of 5.64% copper, including approximately 55,000 tonnes grading 8.75% 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 the high-grade centre of the orebody. Opening up of the mining footprint for these high grade, drift-and-fill mining areas entails, by necessity, 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 December was approximately 24,000 tonnes at an average grade of 2.49% copper. Priorities at Kansoko during December were to develop and support major ventilation airways towards the mine's No. 1 ventilation shaft. 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

Miners operating a jumbo drill at the face of a high-grade development drift near the centre of the Kakula Mine. Due to the thickness of the copper ore in this area, the drifts are 10 metres high by 7.5 metres wide (32.8 feet high by 24.6 feet wide), or 75 square metres. For perspective, the height of the drift is close to the height of a standard telephone pole. The average grade of ore in this area is 8.75% copper and the tonnage per blast is approximately 1,000 tonnes, more than double the tonnage per blast in a normal drift

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 over the first five years of operation. 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

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%)

kamoa-kakulacopperprojectminesand stockpiles 269,000

An 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

December's ore production was 7.6% higher than November, with monthly copper grade increasing from 4.85% to 5.36%; pre-production surface ore stockpiles now total approximately 1.52 million tonnes grading 4.03% copper

In December, mining crews at Kakula and Kansoko mined and transported to surface stockpiles approximately 269,000 tonnes of ore grading 5.36% copper. This brings the project's total pre-production high- and medium-grade ore stockpiles to approximately 1.52 million tonnes at an estimated blended grade of 4.03% copper. An additional 622,000 tonnes of low-grade development ore also has been stockpiled on surface

kamoa-kakulacopperprojectminesand stockpiles 269,000

December's ore production was approximately 7.6% higher than the 250,000 tonnes grading 4.85% copper mined in November, and approximately 38% higher than the 194,000 tonnes grading 4.01% mined in October

The ore being mined from the northern portion of the Kakula Mine is transported to surface via the conveyor system and placed on a blended surface stockpile that now contains approximately 900,000 tonnes grading an estimated 4.26% copper

Additional pre-production ore stockpiles are located at the Kakula southern decline (approximately 188,000 tonnes of high-grade ore grading 5.73% copper and 250,000 tonnes of medium-grade ore grading 2.80% copper) and the Kansoko decline (approximately 3,000 tonnes of high-grade ore grading 6.48% copper and 174,000 tonnes of medium-grade ore grading 2.72% copper)

kamoa-kakulacopperprojectminesand stockpiles 269,000

Overall progress of Kamoa-Kakula's first-phase, 3.8-Mtpa mining and milling operation (covering mine infrastructure, concentrator plant and surface infrastructure) now is approximately 68% complete, up from 63% last month. Overall construction of the project's first phase 3.8-Mtpa concentrator plant and associated facilities is advancing rapidly and is approximately 41% complete, up from 35% last month. The concentrator plant remains on track to be mechanically complete in Q2 2021, with first copper concentrate production scheduled for July 2021

Civil works for the first concentrator plant is effectively complete (30,135 cubic metres of concrete poured from a total of 31,407 cubic metres) with all areas handed over and well advanced in steel, mechanical, piping and platework (SMPP) erection and installation

A number of areas 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

kamoa-kakulacopperprojectminesand stockpiles 269,000

Delivery of equipment to site is nearing completion with all structural steel, platework and piping delivered. The last truckloads of electrical cable are on route from the port of Durban, South Africa, and are expected to arrive this month. The sand filter plant and the last shipments of switchgear are scheduled to arrive in February and March 2021, respectively. More than 2,190 truckloads of equipment have been delivered to site

Less than 680 tonnes (of a total of 4,882 tonnes) of plant structural steel remains to be installed, and 635 tonnes of platework have been installed out of a total of 863 tonnes. All steel and platework is expected to be installed in the next five to seven weeks. With the bulk of the steel structures now complete, the SMPP contractor is focusing on piping and sheeting installation. Approximately 23 kilometres of piping has already been installed

Electrical installation in a number of areas is progressing well, with the milling area 20% complete and a number of other areas such as crushing, flotation, tailings handling in excess of 10% complete. The initial focus is on cable racking and cable installation - 48,000 metres (48 kilometres) of copper electrical cable have been installed out of a total of 207,000 metres (207 kilometres)

kamoa-kakulacopperprojectminesand stockpiles 269,000

Steel erection for Kakula's first phase, backfill paste plant is nearing completion with electrical installation underway. The outer steel structure of the plant has been completed including the installation of the gantry crane. Structural steel erection is scheduled to be completed early this year

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 dam 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 22 kilometres (of a total of 25 kilometres) complete

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 the national power grid, providing clean, renewable 220-kV hydropower; first of six turbines at the refurbished Mwadingusha hydropower plant now synchronized to the national grid

In December, Kamoa-Kakula was connected to the national power grid with the energizing of the 35-kilometre, 220-kilovolt (kV) power line connecting the Western Dispatch substation in Kolwezi to Kamoa-Kakula, supplying the project with reliable and clean hydro-generated electricity

kamoa-kakulacopperprojectminesand stockpiles 269,000

Ivanhoe Mines Energy DRC is pleased to announce that the first of six new turbines at the Mwadingusha hydropower plant was synchronized to the national electrical grid in December. Commissioning of the plant's remaining five generating units, in sequence, soon will begin to ensure that Kamoa-Kakula's power requirements are met ahead of the commissioning of the concentrator plant. The fully-refurbished hydropower plant is expected to deliver approximately 72 megawatts of power to the national 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

Kamoa-Kakula's prevention measures remain strictly enforced, with further prevention being the focus while the world responds to the latest COVID-19 strain. Rigorous testing, physical distancing, wearing of face masks, frequent hand washing and contact-tracing measures are still in place to protect the safety and health of the workforce and community members

kamoa-kakulacopperprojectminesand stockpiles 269,000

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

The stockpile grade estimates contained in this release are based upon bulk ore sampling from earlier underground headings, and vertical channel sample profiles from recent development. Bulk ore sampling was done on each heading every second blast and three 5-kilogram samples were taken. Since the beginning of October 2020, channel sample profiles are the primary data informing the stockpile grade estimates. These are cut approximately 15 metres apart in 1-metre vertical increments across the full vertical exposure using a handheld grinder, with a 100-to-150-gram sample collected. The samples are pulverized at the project's onsite laboratory and analyzed using a portable XRF (pXRF) instrument. Kamoa Copper has routinely analyzed its exploration drill core for copper using pXRF, in addition to analysis at a commercial laboratory using four acid digest and ICP-OES. This data has demonstrated that pXRF results can be relied upon for grade control and run-of-mine sampling

Ivanhoe Mines is a Canadian mining company focused on advancing its three principal joint-venture projects in Southern Africa: the development of major new, mechanized, underground mines at the Kamoa-Kakula copper discoveries in the DRC and at the Platreef palladium-platinum-nickel-copper-rhodium-gold discovery in South Africa; and the extensive redevelopment and upgrading of the historic Kipushi zinc-copper-germanium-silver mine, also in the DRC. Kamoa-Kakula is expected to begin producing copper in July 2021 and, through phased expansions, is positioned to become one of the world's largest copper producers. Kamoa-Kakula and Kipushi will be powered by clean, renewable hydro-generated electricity and will be among the world's lowest greenhouse gas emitters per unit of metal produced. Ivanhoe also is exploring for new copper discoveries on its wholly-owned Western Foreland exploration licences in the DRC, near the Kamoa-Kakula Project
