Analysis of Artisanal and Small-Scale Gold Mining in Peru …
In this paper, we propose a system dynamics (SD) model to examine the dynamics of an informal artisanal and small-scale gold mining (ASGM) supply chain that has interactions with the illegal gold supply chain in the Amazon rainforest region, Madre de Dios (MdD), Peru. In order to examine the system under climate impacts and validate …

A Systemic Analysis of the Environmental Impacts of Gold Mining …
Exploratory modelling of the impact of gold mining on groundwater in a strategic water area of South Africa was undertaken. A systems dynamics (SD) model was developed to simulate the impact of gold mining on water quality, focusing on groundwater contamination risk, within the context of competing developmental priorities around …
Epithermal Gold Deposits | Geology for Investors
Epithermal gold deposits are among the richest gold deposits in the world, with some bonanza-grade ore shoots containing more than 1000 g/t gold-equivalent or a kilogram of gold for everyone tonne of rock mined. The tonnage of ore in epithermal veins is typically smaller than other types of low-grade gold deposits.
