Supergiant porphyry Cu deposits are failed large eruptions [PDF]
, 2021 Abstract Porphyry copper deposits, the principal natural source of Cu and Mo, form at convergent margins. Copper is precipitated from fluids associated with cooling magmas that have formed in the mantle and evolved at variably deep crustal levels, before raising close to the surface where they exsolve fluids and copper.

SULFUR SOURCES OF SULFIDES OF THE AK-SUG CU-AU PORPHYRY DEPOSIT, EASTERN TUVA [PDF]
Минералогия, 2019 The paper presents the S isotopic composition of sulfides from the Ak-Sug Au-Cu-porphyry deposit hosted by Early Proterozoic magmatic rocks. The S isotopic composition of sulfides varies from +1.0 to +3.2 ‰: +2.5 to +3.2 ‰ for molybdenite-I, +1.0 to +3.1
