3 INVESTMENT IN THE CHILEAN MINING INDUSTRY Portfolio Executive Summary Investment in the Chilean mining industry stands at US$112.5 billion. Mining companies have announced 49 projects involving upwards of US$90 million each. Most are in progress or undergoing review, with investment decisions slated for no later than 2017 and start- up by The project portfolio is as follows: SECTOR PROJECTED MINING INVESTMENT (US$ MN) Prior to Subtotal After 2017 TOTAL Share 1) Copper ( ) 10,386 7,701 10,401 10,977 12,805 13,024 54,908 21,425 86, ) CODELCO 3,397 3,969 4,623 4,757 4,552 4,565 22,466 4,683 30, ) Large Private Miners 6,765 3,613 5,390 5,586 7,454 7,735 29,778 16,357 52, ) Medium-Scale Miners , , ) Gold & Silver 3) Iron & Industrial Minerals 3, ,529 2,825 4,125 4,052 13,344 5,050 21, , , , Total (1+2+3) Source: Cochilco, based on published reports. 14,452 9,583 12,855 14,355 17,249 17,259 71,301 26, , The portfolio is led by copper mining, with 28 projects and two additional investment lines. 1 These include Codelco s six structural projects, expansion of megadeposits such as Escondida, Pelambres and Collahuasi, concentrate operations replacing depleted SX- EW operations (El Abra, Quebrada Blanca, etc.), and new undertakings by medium- size miners. Second in line is gold mining, with ten projects accounting for 19.4 percent of investment. Three major gold projects (Caspiche, Cerro Casale, El Morro) will also produce copper while two other replacement projects will help revitalize major gold mining operations. Iron, titanium and nitrate are also attracting fresh investment. Most investment targets are in northern Chile. While Antofagasta leads the way with US$43 billion or 38 percent, new large- scale gold mining operations in Atacama are attracting a healthy US$34 billion or 30 percent. Fully 46 percent of all investment comes from Chilean companies, including majors such as Codelco and Antofagasta Minerals and medium- size Copec and Pucobre. Accounting for the balance are eleven countries, notably Canada (27%) in gold mining and Japan with a wholly- owned operation (Caserones) and a minority stake in several companies. India and China are venturing into iron mining. Due to the nature of the mining business, all investment forecasts are subject to change. In the industry, projects in progress are considered highly certain while those under review are noted for varying degrees of uncertainty. As development moves forward, projects undergo changes that tend to impact expected production capacity, investment amounts, and time frames. 1 Investment by Codelco in development and information projects other than structural projects. 1

4 This update to Cochilco s 2012 mining investment report shows a US$8.2 billion increase in value. This is the result of a US$7.36 billion upward revision of 22 projects plus a net US$900 million gain caused by the entry of nine new projects and the start- up or cancellation of seven other projects in In addition, some project schedules underwent changes ranging from a one- year acceleration to a two- year delay. Overall, shorter- term investments declined and more were shifted to beyond Additions to production capacity were also impacted as a result. Refined copper production capacity in 2021 should stand at 8.1 million tons, rising to 8.4 million once all projects start to operate at capacity. Most of the increase will come from concentrate production, which should rise from 3.7 million tons in 2012 to 6.8 million in By contrast, SX- EW cathode production should decline from 2.3 million tons in 2012 to 1.4 million in One effect of increased concentrating capacity will be a sharper rise in ore volume fed to concentrating plants. Due to persistent declines in copper grades, throughput is expected to rise upwards of 180 percent, from 450 million TPY in 2012 to 1.2 billion TPY in 2021, with concentrate production capacity rising 86 percent from 3.7 to 6.8 million TPY in the same period. As a result, plants are being redesigned on a larger scale, resulting in added costs and requiring more energy, water and other inputs to produce a similar amount of copper, with the attendant impact on demand for these goods and services. Increased productivity is one of the new challenges facing the Chilean mining industry as it seeks to remain competitive. 2

5 I. Introduction The Chilean Ministry of Mines considers investment a strategic pillar of long- term mining growth. This is an industry that turns resources in the ground into tangible wealth that contributes decisively to the economic and social growth of all Chileans. The Chilean Copper Commission (Cochilco) systematically tracks mining investment and reviews planned projects and resulting opportunities. Findings are published annually for the benefit of interested public officials and private industry players. This report provides an update to mining industry investment in Chile, notably projected investment and production capacity potential through the next decade. It has three sections: Inventory of copper, gold, silver, iron, and industrial mineral projects. The tally includes all projects worth upwards of US$90 million either in progress or likely to materialize no later than It does not include initiatives in the exploration stage or below the above amount. Planned investment by Codelco and large and medium- size copper, gold, silver, iron and industrial mineral mining companies. A ten- year projection and review of the mined (concentrate; SX- EW cathode) copper production potential through Includes a global estimate of gold, silver, molybdenum, iron and industrial mineral production. Project amounts, time frames and other information is gleaned from public company reports. While there is no guarantee that projects will materialize as stated, these reports stand as reliable proof of interest and company perceptions of the geological potential and economic and political conditions prevailing in Chile. 2 The methodology is explained in Annex A. Copper mining project details are provided in Annex B. Annex C describes gold and silver projects and Annex D review iron and industrial mineral (iodine, nitrate, potassium salts, titanium oxide) projects. 3

6 II. Mining Project Portfolio As of July 2013, projected investment in the Chilean mining industry stands at US$112.5 billion. Companies have announced 49 projects, including US$86.7 billion in copper mining, US$21.7 billion in gold and silver mining, and US$4 billion in iron and industrial minerals mining.

The remaining 3.6 percent is destined for iron and industrial minerals mining projects. Of this amount, 12.8 percent has been materialized, 63.3 percent will be disbursed in , and 23.8 percent will materialize in The methodology used to compile and process project data is shown on Annex A. 3.2 Investment Distribution by Project Status and Type Projects often run into internal and external issues that force a revision of the original plan. Per the methodological criteria explained in Annex A (2), projects herein are classed as either greenfield (i.e., new) or brownfield (i.e., replacement or expansion of existing operations). In terms of status, they are in progress or in the feasibility or prefeasibility stages. These factors help more accurately assess the likelihood of materialization as stated. Conditions assessed are baseline, probable, and possible. 5 5 Baseline: In progress and highly probable.

Overall, 46.4 percent of investment comes from Codelco, Antofagasta Minerals and other Chilean majors. With a conspicuous focus on gold, Canada comes second. Japan stands third with a wholly- owned operation (Caserones) and a minority stake in several companies. 3.5 Portfolio Comparison, The investment portfolio to June 2013 includes 49 initiatives worth US$112.5 billion, a US$8.25 billion increase from 47 projects and US$104.3 billion reported in June Changes in project value and composition are as follows: (a) Five projects worth US$1.7 billion were omitted due to start- up. (b) The US$963- million San Antonio Oxides project was canceled. Codelco is reviewing other options to ensure continuity of its Salvador Division. 6 See Inversión en la Minería Chilena - Cartera de Proyectos DE/04/

12 (c) Five copper, two gold and two iron projects worth US$3.6 billion were added. (d) The estimated value of investment stays consistent at US$20.2 billion or ten projects. (e) Seven projects revised investment amounts by US$3.09 billion to US$19.7 billion. Time frames remained unchanged. (f) Eight projects will be delayed from one to three years although investment remains unchanged at US$30.6 billion. Further changes are likely. (g) The cost and time frame of 13 projects were redefined. Costs increased a net US$3.92 billion to US$32.32 billion while start- up will be delayed from one to two or more years. (h) Codelco investment in miscellaneous research and development projects increased US$340 million. Where no official announcement exists (Cerro Casale, Collahuasi Phase III, Inca de Oro, Relincho), start- up is estimated based on available information and the methodology on Annex A(5).

13 IV. Projected Copper Production to 2021 By expanding Chilean production capacity, particularly in copper, the investment process underway will help sustain an increased supply to consumer countries. This chapter estimates maximum copper production capacity by 2021 from operations both existing and planned. 4.1 Mined Copper Production Capacity Through 2021 Mined copper production capacity includes concentrate and SX- EW cathode production. The methodology is shown in Annex A(5). Maximum mined copper production capacity is shown in Table 10. Details by producer are shown in Annex G. The table shows maximum production capacity in 2012 and information for 2013 to 2021 by operation and project status, based on data reported to Cochilco. Annual changes in total maximum production capacity are also shown.

Extent and use of maximum production capacities have a long- term impact on mining and related activities, especially the supply of goods and services, an endeavor of strong local relevance. While actual production expected in the next few years will not necessarily use the full installed capacity, maximum production profiles are a valuable tool for estimating demand for related goods, services and human resources across regions and nationwide. The charts below shows the expected behavior of both concentrate and hydrometallurgical operations and projects.

16 4.3.1 National Forecast Chilean mined copper production should rise to a maximum of 8.2 million tons refined copper in the next decade, a 36.8 percent increase over the nearly 5.5 million tons estimated for The annual rate of growth for the period would be 3.2 percent. By 2022, depletion and end of mine life will cut output from existing operations, not considering new investment amounts some of them will require, to 3.64 million tons refined copper, 2.35 million tons less than the baseline year (2012). Therein lies the importance of materializing projected investment plans, as these would add 4.55 million TPY or 56 percent of maximum production capacity estimated for Planned developments rely mainly on increasing concentrate capacity from 3.7 million tons in 2012 to 6.9 million tons in 2022, for an annual rate of growth of 6.4 percent. With that, concentrate output as a share of mined copper production would expand from 62 percent in 2012 to 84 percent in Hydrometallurgical copper is expected to slide from over 2 million tons SX- EW cathodes in recent years to some 1.9 million tons through 2018 and 1.32 million by Causes include a declining number of hydrometallurgical projects, depletion of leachable ores and closure of major operations, notably Codelco s Salvador, Mina Sur, and Radomiro Tomic Oxides, as well as Quebrada Blanca and other private operations. That said, Codelco and other players may yet move to prolong the lifespan of some operations while others may shift to mining underlying primary sulfides Maximum Production Capacity By Likelihood While the above capacity is estimated based on all projects materializing as stated, mining projects are inherently subject to change. As such, maximum production capacity profiles are classed per the criteria in Annex A(2) in a manner similar to the corresponding investment profiles. Table 10 shows that maximum production remains subject to internal and external contingencies. The baseline profile, consisting of existing operations and projects in progress, should stand at 4.6 million tons refined copper by This is equivalent to only 77 percent of maximum production capacity in 2012 and to 57 percent of estimates for 2021, which explains the critical nature of the less advanced projects reviewed below. The probable profile, which includes projects in the feasibility study stage by companies with existing operations in Chile and slated for start- up no later than 2017, should add an additional 1.8 million tons, 390,000 tons above the current maximum production capacity. The largest quantitative increase should come from possible projects, which includes those in the preliminary feasibility study stage and new entrant projects with feasibility study underway. These would add a combined 1.7 million tons or 21 percent of total maximum capacity expected in Production stood at 3.40 million tons concentrate and 2.03 million tons SX- EW cathodes, for a total of 5.43 million tons. 14

In Atacama, refined copper production capacity should jump 194 percent from 409,000 tons in 2012 to 1.2 million tons in 2021 due mostly to the copper output of three major gold projects and four other medium- and large- scale copper mines. These projects should significantly boost mining and related activities in the region. Production in Tarapacá should expand 96 percent to some 1 million tons by 2021, driven mostly by the Collahuasi Phase III Expansion and the new Quebrada Blanca undertaking. However, most projects in Atacama and Tarapacá remain classed as Possible and thus subject to change. As an established mining district, Antofagasta is expected to retain the lead. While maximum capacity should rise 19.6 percent to about 3.95 million tons refined copper, projects are either in progress or have feasibility studies well underway. As some major operations, including RT Oxides, Chuquicamata Open Pit and Mina Sur, are being wound down, most new projects are designed to recoup capacity. The Andina expansion in Valparaíso is expected to increase output by 32.5 percent in the period. The single- largest project in O Higgins is the new El Teniente mine level, also designed to recover production capacity. 4.4 Maximum Concentrate Processing Capacity As the roster shows, most projects are designed to increase copper concentrate production. With grades declining across the board, new plants are being designed to handle a larger throughput. As plant requirements are driven by throughput rather than output, larger, more expensive processing facilities, increased ore and overburden extraction and additional milling and flotation work translate into higher consumption of fuels, power, water and other key inputs. Shown below is annual concentrating plant throughput from existing and new operations coming on stream. 15

By 2021, these projects are expected to increase maximum production capacity to 178 tons, up 256 percent over the 49.9 tons reported in At present, primary gold production contributes some 30,000 kg/yr. while production secondary to copper mining contributes an additional 19,870 kg/yr. Future contributions from both sources are estimated at 145,600 and 39,800 kg, respectively, both from existing operations and new projects coming on stream. Silver projects in this report should contribute some 1,526 TPY to maximum production capacity. Sources when fully operational in 2021 are gold mining (1,226 TPY) and copper mining (300 TPY). 17

20 5.2 Molybdenum Most molybdenum produced in Chile is a byproduct of copper mining. Major copper concentrate projects in the portfolio (Caserones, Sierra Gorda, Esperanza Upgrade, Quebrada Blanca Phase II, Relincho) 8 contemplate producing 36.7 ktpy molybdenum concentrate.

22 VI. Concluding Remarks The overall investment portfolio includes 49 initiatives worth an overall US$112.6 billion. Leading the field is the copper mining industry, with 30 initiatives worth US$86.7 billion. Highlights include: The Codelco investment plan focuses on six structural projects (Ministro Hales Mine, Radomiro Tomic Sulfides Phase II, El Teniente New Mine Level, Andina Phase II, Andina Pit- Plant Transfer) designed to ensure long- term sustainability. Codelco has two additional investment lines covering a range of smaller projects. Large private miners (Escondida, Los Pelambres, Collahuasi) hold reserves that stand among Chile s and the world s largest. They are currently expanding operations in order to raise productivity and prolong mine lifespan. A distinctive element are copper concentrating projects taking over from fast- depleting leachable surface ore operations (RT Sulfides, QB Hypogenic, El Abra Mill, Lomas Bayas Sulfides). The result will a net increase in copper production capacity. New entrants reflect sustained interest in joining one of the world s leading mining districts. Second in line with ten projects and 19.4 percent of overall investment is gold mining. Highlights include: Three large- scale projects (Caspiche, Cerro Casale, El Morro) will also produce copper, while two replacement projects will be instilling new life into major gold mining operations. The binational Pascua- Lama project is being required to ensure its activities are compatible with the law, after which construction could resume. Atacama is the second- largest investment destination, most of it going to gold mining. The portfolio also includes five iron, four nitrate and one titanium dioxide mining project, all at widely varying stages of development. As is often the case in the industry, projects in progress are considered highly certain while those under review are noted for varying degrees of uncertainty. As development moves forward, projects undergo changes that tend to impact expected production capacity, investment amounts, and time frames. Such variability is reflected in this update to the mining project portfolio. This report shows a US$8.2 billion increase in value. This is the result of a US$7.36 billion upward revision of 22 projects plus a net US$900 million gain caused by the entry of nine new projects and the start- up or cancellation of seven other projects in In addition, some project schedules underwent changes ranging from a one- year acceleration to a two- year delay. Overall, shorter- term investments declined and more were shifted to beyond Additions to production capacity were also impacted as a result. Refined copper production capacity in 2021 should stand at 8.1 million tons, rising to 8.4 million once all projects start to operate at capacity. 20

23 Most of the increase will come from concentrate production, which should rise from 3.7 million tons in 2012 to 6.8 million in By contrast, SX- EW cathode production should decline from 2.3 million tons in 2012 to 1.4 million in One effect of increased concentrating capacity will be a sharper rise in ore volume fed to concentrating plants. Due to persistent declines in copper grades, throughput is expected to rise upwards of 180 percent, from 450 million TPY in 2012 to 1.2 billion TPY in 2021, with concentrate production capacity rising 86 percent from 3.7 to 6.8 million TPY in the same period. As a result, plants are being redesigned on a larger scale, resulting in added costs and requiring more energy, water and other inputs to produce a similar amount of copper, with the attendant impact on demand for these goods and services. Increased productivity is one of the new challenges facing the Chilean mining industry as it seeks to remain competitive. 21

24 1. Scope Annex A - Methodology This report covers investment in replacement, expansion or new copper, gold mining, iron and industrial minerals projects by Codelco and medium- and large- scale private miners. It considers projects worth upwards of US$100 million either in progress or likely to materialize in The Prior to 2013 category refers to project outlays (i.e., studies, construction) made through 2012, followed by estimated outlays through Projects scheduled for start- up beyond 2017 are identified as such. Project particulars are complemented by estimations on copper output added, if any, plus notes on current status. Information is provided on a best- guess basis, based on data current at the time of writing. Where no such data is available, annual investment allocations are estimates not necessarily supported in sources. 2. Project Type, Stage of Development and Likelihood Investment information is qualified by project type and stage of development. Projects are ranked from most to least likely. 2.1 Project Type This classification provides information on project likelihood, which varies for existing and new operations. Categories are as follows: a) Replacement: Includes brownfield projects designed to prolong the life of the mine and maintain existing production by addressing declining grades and/or depletion issues. b) Expansion: Includes brownfield projects designed to increase operating capacity, scale up production and cut unit costs, notably as ore grades start to decline. c) New: Includes greenfield projects requiring environmental and other clearances, construction of facilities and opening up a new site. Also includes brownfield projects involving a complete change from one mode of production to another (i.e., leaching to concentrating), which often requires developing an entirely new deposit. 2.2 Stage of Development Based on the assumption that projects in a more advanced stage of development are often more likely to materialize, these are classed as follows: a) In Progress: Investment approved and permits secured. Detail engineering and construction underway. b) Feasibility Study Stage: Undergoing feasibility and environmental (EIA or DIA) review, investment decision not yet made. c) Prefeasibility Stage: Undergoing initial review; decision to proceed to next stage not yet made. 2.3 Likelihood Projects are ranked as Baseline, Probable or Possible based on type and stage of development. 22

25 a) Baseline: In progress. Deemed highly probable, although start- up may undergo delays. Production is added to that of existing operations. b) Deemed Probable: Includes feasibility- stage replacement, expansion or new projects by companies with operations in Chile, with start- up scheduled for While subject to significant changes or delays, they are deemed certain as they prolong the lifespan of existing operations. c) Deemed Possible: Includes feasibility- stage projects by new entrants, replacement or expansion projects with start- up scheduled no earlier than 2018, and all prefeasibility- stage projects. Projects by new entrants often face hurdles that can cause significant changes and delays, or even cancellation. In the case of brownfield projects, a far- off start- up date often results in major revisions that can also cause significant changes and delays. 3. Codelco Investment Plans and Sources of Information Investment estimates 11 are based on information presented in Codelco s 2013 Business and Development Plan (PND 2013) for development and/or research projects. Development projects are directly connected to production prospects and approval requires compliance with certain return on investment standards. These include: a) Structural Projects: Selected development projects that fully leverage available mineral resources and provide a baseline for long- term growth. This report provides specifics and investment amounts. b) Other Development Projects: Included in the Codelco investment portfolio are discrete or shorter- term projects deemed complementary to structural projects and thus essential to company continuity. This report provides specifics and investment amounts. Codelco also implements research projects designed to acquire new information considered relevant to further development. While not listed as part of a specific investment project, these include prefeasibility, feasibility, and environmental assessment of prospective sites, basic and generative exploration, and R&D. Given their manifold nature, these projects are reported on the aggregate. While outlays on equipment replacement, facility upgrades, environmental cleanup, workplace safety, and employee benefits in the PND 2013 also require API approval, they are omitted in order to facilitate comparison with private firms which do not provide such information. Also omitted are investments not requiring API approval and thus outside the purview of this report. All information is gleaned from public reports provided by company officials or on the Codelco web site, complemented by data contained in the Codelco Business and Development Plan and other official reports submitted on a regular basis to the Cochilco Investment Evaluation & Enforcement and Compliance Department (DEIF). As such, the information herein should be construed as a strategic planning tool rather than as binding on the reviewing agencies. 4. Private Mining Investment and Sources of Information Sources include public reports and announcements culled from company web sites, the news media, trade publications, and filings to the environmental assessment system. 11 Spending by Codelco requires Investment Project Authorization (API), a review conducted jointly by Cochilco and the Ministry of Social Development. Disbursements considered as investments by Codelco (i.e., deferred expenses and the like) which require no authorization are not included. Inclusion in the 2013 PND does not imply authorization. 23

26 Often only global amounts and intended start- up year are known. In such cases, annual estimates are based on tentative completion time frames reported to the environmental assessment system or on empirical knowledge of like projects. The review includes all projects under construction. Projects under review were checked for progress and their investment, start- up schedule and estimated production profiles were updated based on the most recent information available. Changes noted included: a) New principals following changes in ownership. b) Production capacity and products of interest. c) Investment amount, start- up date and project schedules. d) Inclusion of new projects. e) Removal of recent start- ups. f) New requirements, such as the use of seawater. While projects are assumed to reflect outlays made during the construction stage, prior outlays may be included. Where no precise information is available, start- up year is estimated as shown below. 5. Estimating Start- up Dates Internal and external factors may impact project development. Some of the latter include the need to cut electricity costs, modify environmental impact statements and/or secure construction permits. The former, for their part, often encompass project timing relative to corporate goals, securing financing, and the need to enhance investment and/or operating cost indicators. Where no public start- up date announcement exists, Cochilco uses the following methodology: a) A standard one- year delay is deemed if a project is impacted by external factors, even if these entail only minor changes to the feasibility study. b) A standard two- year delay is deemed if a project requires reformulating a prefeasibility or feasibility study. 6. Projected Mined Copper Production Capacity Maximum potential concentrate and/or SX- EW production capacity is the sum of maximum production profiles by existing mining operations and projects starting up within the decade, shown as tons of refined copper. Future profiles for existing operation are based on recent production performance and estimation of key parameters, including ore grades, concentrating plant capacity, and acid consumption by hydrometallurgical operations. Assumptions are based on maximum plant capacity operating nonstop 360 days a year, based on data reviewed by Cochilco. Project production profiles are based on company descriptions of maximum processing capacities under nonstop operation 360 days a year and key expected mining and metallurgical parameters. Tracking project rankings, production profiles are also classified from most to least likely. All figures are shown as estimated maximum potential capacity relative to 2012, based on the most recent data available as of this writing. 24

27 Annex B - Copper Mining I) STRUCTURAL CODELCO PROJECTS ( MINISTRO HALES MINE (Ministro Hales Division) Ministro Hales stands in Antofagasta, halfway between the Chuquicamata minesite and the city of Calama. It is a copper sulfide deposit holding reserves estimated at 289 million tons with 0.96 average copper grades and high silver content. The homonymous Codelco Division was set up to develop and operate this mine. Once in operation, the mine is expected to process up to 50 ktpd in a concentrating plant sited adjacent to the open pit. Processes handled include primary crushing, transport by conveyor belt, stockpiling, milling (one SAG mill and two ball mills), and flotation. High arsenic levels will require fluidized bed roasting (up to 350 ktpy) yielding high- grade concentrates (37% refined copper content) to produce some 183 ktpy refined copper and 300 TPY silver. Plant gases will be abated in a sulfuric acid plant. Due to their special characteristics, these concentrates may also be used as smelter feed or sold. Massive pre- stripping has created an opportunity to leverage a significant volume of leachable ores. As such, a complementary project now underway will convey ores to a heap leaching site, with the resulting solution fed to the Chuquicamata Division Hidrosur SX- EW Plant for an expected 79,000 tons refined copper in This is a deep deposit and plans include moving to underground mining in the future. Workforce: 3,000 during construction; 450 during operation. Throughput: 50 ktpd sulfide ores. Est. Investment Amount: US$3.43 billion. Under construction. Once concluded, dry (primary crusher, stockpile), wet (milling, flotation, tailings thickening) and roasting systems will be load- tested. Start- up slated for late

28 RADOMIRO TOMIC SULFIDES PHASE II (Radomiro Tomic Division) Phase II involves mining sulfides emerging at Radomiro Tomic as overlying oxides become depleted. Estimated reserves stand at 2.6 billion tons with 0.48 average copper grades. Plans are to continue mining the current open pit and process ores in a 200- ktpd concentrating plant slated to come on stream in late This will add an estimated 350 ktpy refined copper and 7 ktpy molybdenum concentrate. The project will extract and desalinate seawater at a 1,600 l/s reverse osmosis plant, then pump it 160 km to an altitude of 3,000 m. A conventional tailings dam will be used through 2021, then replaced by thickened tailings technology that will allow for optimized dam use and sizing, help reclaim more water, and reduce particulate emissions. This will require subsequent construction of a high- density thickening plant. The Division also plans to leverage the available hydrometallurgical infrastructure to bioleach low- grade sulfides. Workforce: 12,100 during construction; 2,200 during operation. Throughput: 200 ktpd sulfide ores. Est. Investment Amount: US$5.43 billion, including desalination and pumping infrastructure but not the thickening plant. Finalizing feasibility and investment approval. Environmental, sector and construction permits secured in 2014, start- up expected in late NEW MINE LEVEL (Teniente Division) The project involves mining a new sector at altitude 1,880 m, 100 m below the current mine level, thereby adding an extra 2 million square meters of mining surface. Reserves stand at 2.02 billion tons with 0.86 average copper grades and 220 ppm molybdenum. Mining will be based on panel caving, with 100 percent of the area preconditioned with hydraulic fracturing. The mine level scheme will be characteristic El Teniente: sinking, production, ventilation, haulage, and crushing. Ores will be sent to the surface Colón concentrator by conveyor belt. 26

29 The project will ensure the long- term 137- ktpd divisional target and extend the life of mine for over 50 years after 2017, while creating an option to increase throughput to 180 ktpd within a decade. The project calls for 98,450 m of horizontal tunnels and 3,454 m of vertical air shafts and transfer pits to be built in Workforce: 3,500 in the construction stage. Throughput: 137 ktpd sulfide ores, up to 180 ktpd within a decade. Est. Investment Amount: US$3.5 billion. In progress. Engineering and construction of the 16- km, two- way Maitenes- Confluencia road was awarded in November Gradual start- up expected in H CHUQUICAMATA UNDERGROUND (Chuquicamata Division) Codelco is exploring reserves estimated at 1.65 billion tons with 0.71 copper grades deep under the existing Chuquicamata mine. Plans call for using block caving methods on four underground mining faces. Works to be built include a 7.5- km main access tunnel, five clean- air injection ramps and two air exhaust pits. Production would start at 2.7 ktpd, then climb up to a design capacity of 140 ktpd nine years later, eventually adding 366 ktpy refined copper and over 18 ktpy refined molybdenum. Start- up would coincide with the end of open pit economic life, with ores feeding existing concentrators. Workforce: 3,767 during construction; 4,837 during operation. Throughput: 140 ktpd sulfide ores. Est. Investment Amount: US$4.08 billion. Finalizing feasibility study and building early works. Scheduled for 2013 are construction of main and ventilation tunnels and deepening the air exhaust shaft. Environmental Assessment Resolution (RCA) has been secured. Gradual production would start in

30 NEW ANDINA: PHASE II KTPD EXPANSION / (Andina Division) Phase II of Andina Division plans to harness its full potential calls for upgrading mining and processing capacity from 94 to 244 ktpd. Plans call for significantly expanded mining operations, a new 150- ktpd concentrating plant with primary crushing, ore transport and secondary and tertiary crushing facilities, collective and selective flotation and molybdenum leaching plants, a filtration plant, and a concentrate storage site in Montenegro, near Santiago. The expansion should add 343 ktpy refined copper, helping the Division produce an overall 600 ktpy. Phase III, calling for expanding capacity to 290 ktpd, is under review. Also considered is underground development of the Sur- Sur Mine once the third panel is shut down. Given the vast amount of low- grade sulfides generated by massive mining operations, forced leaching is being considered to help mitigate the environmental impact of acid water. Phase III is not considered in this report. Workforce: Not available. Throughput: An additional 150 ktpd sulfide ores. Est. Investment Amount: US$6.74 billion. Feasibility study started in September 2009, expected completed in Environmental Impact Assessment Review was refiled in January. Replies to 2,200 queries received in April must be filed by September. Start- up not expected before NEW PIT- PLANT TRANSFER / (Andina Division) Includes all work required to replace the current Don Luis pit/crushing plant ore transfer scheme, as plant location will be impacted by development of the new pit required to feed the new 94 ktpd capacity. Works include building a platform at node 3,500, a cave- in protection system, a new primary crusher, the Haulage III conveyor tunnel, a SAG hopper distribution and feed system, and a new secondary crushing plant. The project will extend pit life through Workforce: Not available. Throughput: N/A. Est. Investment Amount: US$1.42 billion In progress, early work underway, basic engineering proceeding concurrently. Expected operational in

31 II) Major Private Copper Miners 2.1 Antofagasta Minerals ( ANTUCOYA (Minera Antucoya Ltda.) Located 125 km NE of Antofagasta and 45 km from the coast, with proven and probable reserves of 642 million tons and 0.35 copper grades (0.21 cutoff grade). Expected to produce 85 ktpy copper cathodes through the first decade, then settle at 80 ktpy through the second and last decade of expected life. Antucoya will be a conventional open- pit mine. Ores will be leached in a dynamic heap and processed in an SX- EW plant using raw seawater. Albeit a low- grade greenfield project, the orebody is relatively shallow and pre- stripping to remove some 35 million tons of overburden should take only nine months. The overburden/ore ratio is a low 1:1 and the deposit lies within a established mining zone, which ensures ease of access to existing infrastructure, including energy, water, and human resources. Construction was halted in late December 2012 to revise the project given rising current and potential costs. Following adjustments, construction restarted in Q Workforce: 5,000 to 7,000 during construction, 1,400 during operation. Throughput: High- grade ores to 96 ktpd; run- of- mine to 38 ktpd. Est. Investment Amount: US$1.9 billion, not including a potential acid plant. In progress after restart. Start- up expected in mid CENTINELA DISTRICT The Centinela mining district (formerly Sierra Gorda) is the main focus of Antofagasta Minerals exploration targets in Chile. The Group owns or controls several copper oxide and sulfide deposits in this 30- km long district located in the homonymous municipality. These include Esperanza, El Tesoro, Esperanza Sur and Encuentro (oxides and sulfides). In addition, the Polo Sur prospect holds reserves of 704 million tons with 0.37 grades plus gold and molybdenum. Antofagasta Minerals is also exploring other deposits in the area, notably Penacho Blanco. Reserves at the larger Esperanza Sur (Ex- Telégrafo) and Encuentro (Ex- Caracoles) deposits add up to a combined 4.3 billion tons with 0.36 average copper grades (plus gold and some molybdenum), providing about 30 percent of overall mineral resources held by Antofagasta Minerals. Development plans are as follows: a) Esperanza Sur (Minera Esperanza S.A.) Named for its position at the south end of the Esperanza operation. Resources stand at 2.96 billion tons with 0.34 average copper grades. Sulfide ores account for 2.9 billion tons with 0.34 grades (plus molybdenum and 0.11 g/t gold) while oxides account for some 64.1 million tons with 0.21 copper grades. Esperanza Sur will help support current mining plans and gradual expansion of the existing concentrating plant. 29

32 On- site studies show that on the order of 150 million tons of material will need to be pre- stripped, including 50 million tons of oxide resources that could be processed by the El Tesoro SX- EW plant starting in As to sulfide resources, a new concentrating plant could add some 140 ktpy copper and 160,000 oz. gold through the first ten years, over an estimated total lifespan of 34 years. Workforce: Not available. Throughput: An additional 95 ktpd sulfide ores. b) Encuentro (Antofagasta Minerals S.A.) Encuentro stands 10 km SE of Esperanza. Resources are an estimated 1.3 billion tons with 0.41 average copper grades. Sulfides account for 1 billion tons with 0.41 copper grades (plus percent molybdenum and 0.15 g/t gold), while oxides stand at 212 million tons with 0.40 copper grades. i. Encuentro Oxides: Encuentro requires pre- stripping some 600 million tons, including some 150 million tons of oxide ores that could be processed by the El Tesoro SX- EW plant starting in 2016, extending plant life for an extra eight years. This initiative is known as Encuentro Oxides. The project contemplates a new crushing plant, heap leaching facilities, and piping the pregnant leach solution to the El Tesoro plant for processing. Construction could start in early 2014, provided the Environmental Impact Assessment Review (EIA) filed in December 2012 is approved in Construction should extend through two years, with first production expected in The project could add some 50 ktpy copper cathodes over eight years. Workforce: 2,000 during construction; 500 during operation. Throughput: About 65 ktpd, including high- grade ores and run- of- mine. ii. Encuentro Sulfides: Current plans call for accessing sulfides once oxide mining begins. An independent feasibility study based on results from a preliminary feasibility study completed in 2012 is being conducted to this effect. Encuentro Sulfides could support a 95- ktpd concentrating plant producing ktpy copper and ,000 oz. gold over 22 years. Tests show that raw seawater can be used to process sulfide ores directly. Workforce: Not available. Throughput: 95 ktpd sulfide ores. Est. Investment Amount: US$7.6 billion (Esperanza Sur: US$3.5 billion; Encuentro Oxides: US$600 million; Encuentro Sulfides: US$3.5 billion). Feasibility study underway. Plans are to begin construction of Encuentro Oxides in 2014 and start- up in Depending on progress on additional feasibility studies, Esperanza Sur might begin production no earlier than 2017 and Encuentro Sulfides in

33 ESPERANZA UPGRADE (Minera Esperanza S.A.) Minera Esperanza, 30 km from Sierra Gorda, in Antofagasta, is optimizing its operations through two Environmental Impact Statements (DIA) filed in Esperanza Upgrade III, the first of these, had its DIA approved in May It seeks to increase the supply of critical inputs (water, process inhibitors and reagents, etc.), process oxide ore resources in areas to be cleared for use as dumpsites, and construction of a new molybdenum processing plant. The leading component is a molybdenum plant to be built near the collective flotation area, next to the existing concentrating plant. This includes a standard 5.5- ktpd selective flotation circuit encompassing primary flotation, cleaning flotation, filtration, drying, and concentrate storage. The resulting copper- gold concentrate will be the tailings to be sent to the existing concentrating plant for processing. The Esperanza Upgrade IV Process Optimization, whose DIA was filed in June, focuses on improving existing milling and flotation systems through a secondary and tertiary crushing plant designed to complement current capacity. Plans also contemplate new concentrate and tailing thickeners. Once completed, the Esperanza upgrades will boost concentrating plant throughput by 12 ktpd to 105 ktpd, which would translate into an additional 19 ktpy copper concentrate. The molybdenum plant will produce an estimated 11.5 ktpy during operation lifespan. Workforce: 875 during construction; 49 during operation. Throughput: An additional 12 ktpd sulfide ores and 5.5 ktpd molybdenum. Est. Investment Amount: US$550 million (Esperanza Upgrade III: US$200 million; Esperanza Upgrade IV Process Optimization: US$350 million). Under construction and feasibility study underway, respectively. Upgrade III secured approval of its Environmental Impact Statement (DIA) in May 2012 while Upgrade IV awaits approval of DIA filed in June Start- up for both expected no earlier than LOS PELAMBRES EXPANSION IV (Minera Los Pelambres S.A.) Los Pelambres stands 170 km east of Los Vilos, at an altitude of 3,100 m. Baseline resources stand at 5.6 billion tons with 0.52 copper grades (plus molybdenum and 0.03 g/t gold), over four times the current operation reserves. The company is exploring two long- term development options. Option 1 requires no new infrastructure and involves increasing concentrating plant capacity by up to 15 percent. Option 2, or Los Pelambres Expansion, seeks to increase processing capacity by 175 ktpd. The company has been conducting a preliminary feasibility study of both options since Last year a drilling campaign succeeded in reclassifying available mineral resources. While the long- term goal is to double the ore processing capacity, the project will proceed gradually to ensure sustainability. Workforce: Not available. Throughput: An additional 175 ktpd sulfide ores. 31

Start- up expected no earlier than 2021; production to rise gradually starting in BHP Billiton ( ESCONDIDA OXIDE LEACH AREA PROJECT (Minera Escondida Ltda.) The Oxide Leach Area Project (OLAP) calls for construction of a new dynamic heap and a system of conveyors designed to maintain oxide leaching capacity at current levels after depletion of the existing heap in Current SX- EW cathode production equipment and facilities will remain in use. Workforce: 420 to 800 during construction; 85 during operation. Throughput: 67.5 ktpd, same as current. Est. Investment Amount: US$721 million. In progress, start- up expected in mid ESCONDIDA ORGANIC GROWTH PROJECT I (Minera Escondida Ltda.) In 2011 BHP reformulated the original Escondida Phase V project as an organic growth project calling for addition of a new mill to the Laguna Seca Plant, increasing plant throughput by 15 ktpd, and build a new 152- ktpd concentrating plant replacing the Los Colorados facility, slated for decommissioning to clear the area for new mining. Plans include a second organic growth project (OGP II) which calls for adding a third plant, a seawater desalination facility, and power line infrastructure. OGP II is at the scoping study stage. Workforce: 5,900 to 8,570 during construction; 739 during operation. Throughput: Net 47 ktpd sulfide ores increase: a) Boost Laguna Seca Plant by 15 ktpd to 135 ktpd sulfide ores. b) Decommission 120- ktpd Los Colorados plant. c) Add 152- ktpd concentrating plant. Est. Investment Amount: US$3.83 billion. In progress since February 2012, 30 percent completed in June Concentrating plant start- up expected in Q

35 2.3 Capstone Mining ( SANTO DOMINGO (Minera Santo Domingo) Santo Domingo is the largest of four IOCG deposits being reviewed by Capstone Mining in the Diego de Almagro district following its June 2011 acquisition of Far West Mining. A preliminary feasibility study completed in August 2011 reassessed project investment and operating parameters. Available information suggests possible development of sulfide resources to produce over 100 ktpy refined copper, 470 kg/yr. of gold, and 4 million TPY iron ores (magnetite and hematite). Workforce: Not available. Throughput: 70 ktpd sulfide ores through the first five years, 63.5 ktpd sulfide ores thereafter. Est. Investment Amount: US$1.8 billion. Feasibility study and preparation of Environmental Impact Assessment Review underway. In late 2012 the company deferred completion of feasibility study to 2014 and start- up to no earlier than 2017, assuming reasonable electricity costs. 2.4 Doña Inés de Collahuasi ( COLLAHUASI EXPANSION (PHASE III) Collahuasi is expanding its ore processing capacity from 140 to 270 ktpd with a view to boosting refined copper production to +1 million TPY. Expansion plans, first designed to boost processing from 140 to 270 and then to 260 ktpd, had a new stage added in a) Phase I, completed in October 2011, optimized facilities for throughput of 150 ktpd. b) Phase II, completed in Q2 2013, is part of optimization plans designed to achieve a 160 ktpd processing rate. Last March SAG mill 3, which handles nearly two- thirds of site output, underwent the necessary overhaul during a scheduled 45- day shutdown. c) Phase III, currently undergoing a preliminary feasibility study, would add 1 or 2 milling lines designed to boost processing to ktpd in order to achieve Collahuasi s +1 million TPY refined copper target. Workforce: Not available. Throughput: An additional 260 to 350 ktpd sulfide ores. Est. Investment Amount: Phase III: US$6.5 billion. Phases I and II completed. Per Collahuasi s 2012 Annual Report, Phase III expansion will remain in the prefeasibility stage until operating stability is restored.
