... for Chuquicamata in the east to 75 ka for Michilla on the Pacific coast. We propose that anomaly formation at the surface and saline metasomatism of supergene oxides were parts of the same process, which occurred after the climate became hyper-arid. Tectonic de-watering of the forearc basin sent saline waters...

... Abstract This chapter describes the metallic ore deposits of Chile, their mineralized host rocks and the processes involved in ore formation, and provides a brief overview of the mining history of this Andean copper-rich country. The ore deposits are ordered according to their respective...

... of world-mined Cu. The ~6,000-km-long Andean Cu province comprises several long and markedly linear, orogen-parallel metallogenic belts, each developed during a restricted metallogenic epoch. Belts in the northern Andes are still poorly explored, those in the central Andes are the focus of current Cu...

... of stationarity in the introductory section. Chapter 7 (16 p.), “Mining dilution,” stresses that ore dilution and loss are critical issues that affect many aspects of mining. It begins with a discussion of recoverable versus in situ resources, covering topics such as economic and marginal cutoff grades...

... ; Vivallo & Henríquez, 1998 ; Kojima et al ., 2003 ; Reich et al ., 2009a , 2010 ). These high-grade, low-tonnage volcanic-hosted stratabound deposits normally contain 1–40 million metric tonnes (Mt) of ore with 1–4 wt% Cu and 8–25 g/t Ag ( e.g. Michilla district, Buena Esperanza, Mantos de la...

.... Within actively eroding areas, such as the bedrock channels, such geologies are difficult to break with a geological hammer, falling into the engineering category “very to extremely strong,” with uniaxial compressive strengths in excess of 100 MPa ( Mining Life, 2005 ). Due to the observed field...

... based on orientation surveys. Today, it is rare to even have a geochemist on an exploration team. The mining industry cannot rely on commercial laboratories to fill the research gap in method development. This has to be led by the companies that have the most to gain in developing and applying the new...
