Mineral-deposit models are the basis for consistent resource-assessment, exploration, and environmental risk analysis methodologies. To reduce uncertainties in these methodologies, improved predictability of deposit occurrence is essential. Advances in understanding about structure and tectonics and the geology of earthquakes, together with improved insights as to how fluid flow is coupled with active deformation, heat transport, and solute transport, provide the framework for integrating mechanical phenomena into deposit models. With this framework, it is possible, for a given deposit type, to predict where in structural systems hydrothermal systems may occur, the chances that significant concentrations of ore may be expected, and where in larger vein arrays ore bodies may be localized. Discussions of porphyry copper and related polymetallic veins illustrate the value of this new generation of deposit models.
