Supergiant porphyry copper deposits are failed large eruptions
Communications Earth & Environment, 2022 Monte Carlo-based mass balance simulations suggest that the formation of porphyry copper deposits requires fast accumulation of large magma volumes, which are also capable of destroying those deposits if magmas erupt.

Geochemistry of Porphyry Deposits
, 2014 Porphyry ore deposits typically form in convergent plate margin or postsubduction settings at depths of 1-6 km. Oxidized hydrous melts derived from the metasomatized mantle wedge transport Cu, Au, Mo, and other metals to upper-crustal magma chambers ...

Large Igneous Provinces (LIPs) and Anoxia Events in “The Boring Billion”
Geophysical Monograph Series, Page 449-486., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.
