Anglo Expects Chilean Copper Recovery Through Strategic Infrastructure Investment

Current Challenges Affecting Chilean Copper Production

Chile's position as the world's leading copper producer faces unprecedented pressures from geological, environmental, and infrastructure constraints that have accumulated over decades of intensive mining activity. Furthermore, Anglo expects Chilean copper recovery to overcome these significant operational challenges through targeted infrastructure investments and strategic partnerships.

Declining Ore Quality Creates Processing Bottlenecks

Copper ore grades across Chile's major mining districts have experienced significant deterioration over the past two decades. According to the Chilean Copper Commission (Cochilco), average ore grades at major Chilean copper mines fell from approximately 0.8% copper content in 2003 to around 0.5% by the early 2020s. This decline forces operations to process substantially larger volumes of material to extract equivalent copper quantities.

Each 0.1% reduction in ore grade increases the volume of material requiring processing by approximately 20%, directly escalating energy consumption and operational costs per unit of copper produced. Lower-grade deposits necessitate expanded comminution (crushing and grinding) capacity and extended leaching or flotation cycles, creating significant operational bottlenecks.

Collahuasi specifically encountered lower-grade ore challenges in 2025, with operations accessing lower-grade material sections before reaching higher-grade deposits later in the year. As noted by Anglo American Chief Operating Officer Ruben Fernandes, the mine will access areas with higher-grade material by the end of the second half, allowing Collahuasi to return to regular production levels.

Water Scarcity Constrains Desert Operations

Chile's Atacama Desert, where Collahuasi operates, represents one of Earth's most arid environments with average annual precipitation below 25mm in the mining zone. According to the UN Environment Programme, Chile experienced severe drought conditions lasting over 15 years in certain regions, with water availability declining by approximately 30% in some mining districts.

Copper extraction and processing operations in desert regions typically require 2-4 tons of water per ton of copper produced in traditional operations. This water dependency creates significant operational vulnerabilities during extended drought periods, directly impacting processing capabilities and overall production capacity.

Collahuasi's new desalination plant reaching full operational capacity in the second half of 2025 represents a critical infrastructure advancement. According to Fernandes, water availability will no longer constrain operations, eliminating historical supply limitations that previously restricted production levels.

Infrastructure Limitations Reduce Operational Efficiency

Aging processing equipment and transportation networks across Chile's mining sector have created substantial operational inefficiencies. According to the International Council on Mining and Metals (ICMM), extraction and processing equipment at several major Chilean copper mines exceeded design life expectations, creating maintenance backlogs and reduced throughput capacity.

Transportation infrastructure optimisation can reduce copper concentrate shipping costs by 10-15%, while modernised processing equipment improves extraction efficiency by 15-30% compared to aging infrastructure. These improvements directly impact operational profitability and production consistency.

Specific Mines Driving Chile's Copper Recovery

The recovery trajectory for Chilean copper operations centres on strategic assets with substantial production capacity and infrastructure advantages that position them for sustained growth. However, effective mineral exploration insights remain crucial for identifying future high-grade ore deposits.

Collahuasi Mine Complex Anchors Recovery Strategy

Collahuasi operates as one of the world's largest copper mines by production volume, with Anglo American and Glencore each holding 44% stakes and a Mitsui-led consortium controlling the remaining 12%. The operation targets approximately 600,000 metric tons annually by 2027, representing full operational capacity recovery.

Key Recovery Elements:

• Higher-grade ore access: Mine planning includes accessing richer ore sections in expanded open-pit areas operational in the second half of 2025

• Desalination infrastructure: New seawater treatment facility provides consistent, year-round water supply independent of precipitation patterns

• Processing capabilities: Modernised extraction and refining equipment maintains production levels while handling varying ore grades

Prior to recent challenges, Collahuasi typically produced in the range of 550,000-610,000 tons annually, making the 2027 target a return to historical performance levels rather than expansion beyond proven capacity.

Los Bronces and Andina Joint Development Project

A collaborative project between Anglo American and state-owned Codelco represents one of South America's most significant copper development initiatives. This partnership targets additional production capacity through integrated operations and shared infrastructure.

The project leverages complementary assets and shared infrastructure to optimise extraction efficiency and reduce per-unit production costs. Environmental approvals and technical specifications remain under development as the partnership advances through regulatory processes.

Infrastructure Improvements Enabling Production Recovery

Comprehensive infrastructure modernisation across Chilean copper operations addresses historical constraints while positioning assets for sustained production growth. In addition, implementing modern mine planning techniques ensures optimal resource extraction and environmental compliance.

Desalination Technology Eliminates Water Constraints

Collahuasi's seawater desalination facility reaching full operational capacity by the end of the second half of 2025 represents a fundamental shift in operational water security. Modern desalination plants produce approximately 3-5 cubic metres of freshwater per day per membrane module, with large-scale facilities comprising multiple modules in parallel configuration.

Technical specifications:

• Energy requirements: Modern desalination plants consume 3-5 kWh per cubic metre of treated freshwater

• Operational costs: Desalination increases per-unit water costs by 200-400% compared to traditional groundwater extraction

• Supply reliability: Provides guaranteed supply independent of climate conditions and drought cycles

According to Fernandes, desalination infrastructure resolves historical water availability constraints entirely, stating that water availability will no longer constrain operations.

Enhanced Processing Equipment Improves Extraction Efficiency

Modernised processing equipment delivers substantial improvements in ore processing efficiency and recovery rates. Flotation plant modernisation increases recovery rates by 5-10 percentage points, while leaching circuit optimisation reduces cycle time by 15-25%, increasing overall throughput capacity.

These improvements allow mining operations to extract equivalent copper volumes from lower-grade ore bodies, effectively extending mine life and improving operational flexibility during transitional periods when accessing different ore zones.

Transportation Network Optimisation Reduces Costs

Infrastructure upgrades across transportation networks reduce copper concentrate shipping costs by 10-15% through improved logistics efficiency. Pipeline optimisation for slurry transport reduces friction losses and energy consumption, while enhanced truck logistics routes decrease fuel consumption and equipment maintenance requirements.

Strategic Partnerships Accelerating Recovery Timeline

International partnerships and joint ventures provide capital, technical expertise, and operational synergies essential for large-scale infrastructure projects and capacity optimisation. Moreover, sophisticated copper investment strategies are increasingly focused on companies with strong operational partnerships.

Anglo-Teck Resources Collaboration Creates Operational Synergies

The proposed merger between Anglo American and Teck Resources, pending regulatory approval, creates significant operational synergies through integrated assets and shared infrastructure. The collaboration would enable Collahuasi's high-grade ore to feed Teck's neighbouring Quebrada Blanca mine, potentially adding 175,000 tons annually and enhancing profitability by an estimated $1.4 billion yearly.

Merger benefits:

• Integrated processing: Shared infrastructure optimises ore processing across multiple assets

• Logistics efficiency: Reduced transportation costs through geographic proximity

• Technical expertise: Combined technical capabilities enhance operational optimisation

According to Fernandes, discussions with Collahuasi partners will commence only after securing regulatory and antitrust approvals for the Anglo-Teck combination, indicating careful coordination of partnership implementation.
