Fluor // 2023 Integrated Report

24 Fluor Corporation PROFILE Client: Anglo American (majority owner) and Mitsubishi Corporation Location: Moquegua region of Peru Type of Project: Grassroots copper concentrator project, including production facility, port expansion and related infrastructure Duration: Began work in late 2018 and completed in 2023 Scope of Work: Engineering, procurement and construction management services for a 127,500-ton-per-day main processing plant as well as related infrastructure, including a river diversion tunnel, water and power supply, roadways, dams, tunnels, pipelines, overland conveyors and a bridge Continuing more than a decade-long relationship with Anglo American, Fluor completed construction on the Quellaveco Open-Pit Copper Mine in 2023. The Quellaveco project site was vast, spreading from the Pacific Ocean to high in the Andes Mountains. Environmental sensitivity played a large role throughout the project, particularly around ensuring a clean water supply for surrounding communities and wildlife. The team built a dam over the Vizcachas River to separate the clean water from the nearby volcanic water streams used for mine operations. They also diverted the Asana River around the mine through a tunnel and hydraulic channel as well as a series of smaller canals built into the mountainsides to collect rainwater and route it to the diversion channel. Substantial infrastructure development was required to build the mine’s facilities, including access roads, high-voltage power transmission lines and substations, a laydown yard and personnel camps. Today, Quellaveco is one of the largest and most technologically advanced copper mines in the world, with features such as autonomous drilling and haulage fleets, a remote operations center, the latest digital twin technology, minimal water usage for steady-state operations and a power supply sourced entirely from renewables. It represents Anglo American’s technologydriven, sustainability-focused mining blueprint and serves as a benchmark for all future mining projects. “This new facility supplies vital copper for the global energy transition, and despite challenging times and tough logistics, the project was delivered on time and on budget. Projects of this magnitude are why many of us joined Fluor – to literally build a better world.” TONY MORGAN Group President, Urban Solutions QUELLAVECO OPEN-PIT COPPER MINE URBAN SOLUTIONS PROJECT SPOTLIGHT Fluor and client leaders celebrate the Quellaveco mine startup // Moquegua, Peru
