2542 The copper price can rise due to supply shortfalls. This will potentially bring additional marginal ore into production. However, it takes time to change metal schedules, as mine plans are constrained by considerations of plant capacity, pit stripping requirements, and underground development schedules. Perhaps, it is more prudent in the immediate term to focus on production improvements from mine to mill and through port to smelters and refineries. The approach to improvement ranges from continuous processes, such as Six Sigma, that much of the industry has adopted, to incremental and step-change improvements (Lean). It is proposed that improving production efficiency should be the focus to increase copper production. This is an area of urgency and focus. Incremental improvements, however, typically deliver modest production increases, often less than 5%, insufficient to close the gap. Innovation will be a critical factor to increase production but requires time to prove technical viability at mine scale, to commercialise and to demonstrate economic value. Innovation will not close the immediate supply gap, but without it, the gap will only widen. Mining has historically been optimised in silos: mine, mill, smelter, port, each maximised independently. This fragmentation leaves unrealised value across the full value chain. The challenge for the industry is to design production as an integrated system, from orebody to final product. This will require collaboration between various stakeholders, including mines, suppliers, and customers. The largest unrealised opportunity is in systems thinking and requires: ● Breaking down silos from mine-to-mill, mill-to-smelter, and mine-to-port ● Deploying digital twins across the entire system ● Treating copper production as a connected flow, not a series of hand-offs ● Actively identifying and eliminating waste, delays, and misalignment across the system Technologies already exist that demonstrate this potential. Real-time ore characterisation, such as sensing grade in the bucket, allows material to be routed appropriately, improving run-of-mine quality (Gorain, B. 2025). High-grade material can be prioritised for milling, while lower-grade sulphides are directed to leaching circuits. Chemistry can be dynamically adjusted, phase changes accelerated through improved maintenance and process control, and material handling optimised across the system. None of this is proprietary magic. Copper milling is not a secret. Yet the industry lacks a structured way to learn collectively. A shared, trusted institute of lessons learned, supported by a robust database from orebody through mining, processing, and smelting, could reduce repeat failures and accelerate performance across the sector. The challenge is compounded by structural constraints, including: ● Lengthy and uncertain permitting processes ● Growing public distrust and declining social licence ● Rising capital intensity and investment risk ● Acute skills and talent shortages Once a potential orebody is discovered, it enters a phase of study to ascertain its technical and economic viability and of course permitting. This can consume time, particularly as communities have high expectations concerning job creation, education, etc. Production is trending deeper and new orebodies are in remoter parts of the world, increasing both capital requirements and operating costs. Project and production risks increase lockstep with these trends, resulting in longer lead times for investment decisions. Talent is a critical constraint. Universities often teach what is academically interesting rather than what is operationally needed. Young professionals increasingly resist remote site-based roles. Cyclical hiring and firing erode institutional memory and prevent the accumulation of deep operational expertise. New models are required: regional mining schools, embedded co-op programs, industry-university partnerships, and place-based talent initiatives such as Rio Tinto’s mining school in Mongolia. Talent development must be treated as a long-term system investment. Copper supply is geographically concentrated. Countries such as Chile, Peru, and Australia will continue to play dominant roles, while political risk, permitting timelines, and social license increasingly shape delivery uncertainty. We cannot assume that all jurisdictions will contribute equally or reliably. At the same time, smaller and mid-tier companies play an important role by focusing on smaller, more complex orebodies that may fall outside the strategic focus of major producers.
