Innovative technologies in development & roll-out Coarse Particle Recovery Flotation process changed An enabler for hydraulic dry stacking Allows material to be crushed to larger particle size: ⚫Throughput increase: +15% to 20% • 20% energy reduction per tonne¹ • Up to 85% water recovery with hydraulic dry stack Capital cost $10m to $150m El Soldado (Copper) • Demo plant construction & commissioning completed in 2021 • Further testing in progress particle recovery unit Mogalakwena North (PGMs) • Constructing full scale system • 100% of volume Quellaveco (Copper) Commissioning expected late 2023 • Treatment of tailings • Start up anticipated Q4 2022 • Recoveries c. +3% over LOM Next planned rollouts Feasibility work continues at Los Bronces (Copper) & Minas-Rio (Iron Ore) • Collahuasi - investigating options 1. Total energy consumed remains the same, but CPR allows the throughput to increase, hence our energy efficiency improves, and energy consumed per tonne treated reduces. Anglo American 80
