Our Copper business has an excellent portfolio of mining operations with substantial growth opportunities and a number of expansion opportunities — both greenfield (new sites) and brownfield (developments on existing sites). This is allowing us to expand our production significantly through various projects.
With a portfolio of large, low-cost mining operations — including the Escondida mine in Chile which is the world's largest single producer of copper — our aim is to become the pre-eminent supplier in copper through capacity expansions, reliable supply and innovative solutions. We also produce uranium oxide concentrate, lead concentrates and zinc concentrates, and provide base metal concentrates to custom smelters and copper cathodes to rod and brass mills and casting plants.
We are also focused on exploration. Our greenfield activities allow us to explore some of the most geologically prospective terrains across a wide array of countries and operating environments. Our exploration activities include opportunity identification, application for and acquisition of mineral title, early reconnaissance operations to multi-million-dollar delineation drilling programs.
