Abstract: Copper plays a crucial role in modern society across the world, contributing to infrastructure, technology, and lifestyles. Although mineral resources are commonly considered to be “finite,” global Cu production has grown steadily throughout the 20th century, and has been matched by substantial growth in estimated Cu reserves and resources. While there is growing concern about “peak oil,” there is very little research about “peak minerals.” In this paper, we present a detailed compilation and assessment of globally reported Cu resources by project and standard deposit types for the year 2010. The minimum amount of Cu reported globally as mineral resources is 1,780.9 Mt Cu, split over a total of 730 projects, with a further 80.4 Mt Cu in China. In addition, our compiled data indicate that global Cu resources continue to increase, despite a coincident increase in Cu production over time, along with declining cutoff and ore grades, increasing awareness of environmental issues, and other related aspects. Our data compilation indicates that the vast majority of global copper resources are hosted by Cu porphyry deposits, especially in Chile, with Cu porphyry deposits containing some 10 times more Cu than any other mineral deposit type. Overall, there are abundant Cu resources already identified that can meet growing global demands for some decades to come the primary factors that govern whether a given project is developed will be social, economic, and environmental in nature.

Abstract: A single mining c or ore deposit can contain multiple mineral deposit types but may have mineral reserves or resources classified by what a mining or mineral exploration company considers to be the dominant mineralization type in the area. In this paper, we summarize recent work on the challenges of reporting mineral deposits by geologic processes rather than by grades, tonnages, and mineral processing approaches. For ex le, the Ertsberg-Grasberg district of Indonesia contains several large skarn Cu-Au-Ag deposits, with the discovery outcrop as well as early production entirely in skarn. All early publications and resource descriptions refer to it as the Ertsberg district. Subsequent discovery of the giant Grasberg porphyry Cu-Au-Ag deposit led to the entire district being renamed Grasberg and classified as a porphyry deposit, despite the skarn-focused discovery and early production history of the deposit, as well as the presence of several large skarn deposits within the district. The Ok Tedi Cu-Au-Ag deposit of western Papua New Guinea also is generally thought of as a major porphyry Cu deposit, yet hosts both porphyry and skarn mineralization. Current reserve estimates indicate that the majority of the contained metal within the deposit is hosted by skarns rather than porphyry bodies. Thus, following the Grasberg ex le in terms of contained metal, Ok Tedi could be classified as a skarn rather than a porphyry deposit. In addition, comparatively minor mineral deposits can prove useful during exploration this is exemplified by the large Au-Cu-Ag porphyry deposits at Cadia in Australia that were discovered by exploring modest skarn deposits using the Ertsberg-Grasberg skarn-porphyry model. Here, we extend a recent global compilation of economic Cu mineral resources by analyzing cumulative production and reserve-resource data for Ertsberg-Grasberg, Ok Tedi, and Cadia, and provide a brief review of a number of other Cu projects that contain multiple mineralization types. Overall, in order to help inform exploration strategies as well as facilitate the development of more comprehensive and accurate mineral deposit models, there is clearly positive value for the mineral exploration and mining industry in reporting ore reserves and mineral resources by mineralization type.
