Magmatic controls on porphyry copper deposit formation and machine learning approaches for mineral exploration

, 2022
Porphyry copper deposits are a rare manifestation of arc magmatism, occurring in restricted spatiotemporal windows within magmatic arcs. Many of the largest deposits are related to the optimal alignment of tectono-magmatic processes, and this magmatic ...

Porphyry copper deposits of the CIS and the models of their formation

Ore Geology Reviews, 1993
Abstract Deposits of the “porphyry” family (essentially porphyry copper and gold-porphyry copper, gold-bearing porphyry molybdenum-copper, gold-containing porphyry copper-molybdenum and porphyry molybdenum deposits) are associated in time and space with granitoid magmatism mainly in Phaerozoic volcano-plutonic belts.

Risk quantification with combined use of lithological and grade simulations: Application to a porphyry copper deposit [PDF]

, 2016
The uncertainty in the recoverable tonnages and grades in a mineral deposit is a key factor in the decision-making process of a mining project. Currently, the most prevalent approach to model the uncertainty in the spatial distribution of mineral grades ...
