Application of machine learning algorithms to mineral prospectivity
Numerous models and algorithms have been attempted for mineral prospectivity mapping in the past, and in this thesis we propose two new approaches. The first is a modified support vector machine algorithm which incorporates uncertainties on both the data and the labels. Due to the nature of geoscience data and the characteristics of the mineral ...

Selection of coherent deposit-type locations and their application …
Data-driven prospectivity mapping can be undermined by dissimilarity in multivariate spatial data signatures of deposit-type locations. Most cases of data-driven prospectivity mapping, however, make use of training sets of randomly selected deposit-type locations with the implicit assumption that they are coherent (i.e., with similar …

Data–driven prospectivity modelling of sediment–hosted Zn–Pb mineral
Regions with low prospectivity scores and high uncertainty should also be considered during mineral exploration decision–making since at least some of the evidence is favourable in these H3 cells. Covered areas with mixed evidence and thus high uncertainty tend to be associated with prospective pathways that were identified using …

1. Introduction. Predictive modeling of mineral prospectivity entails the analysis and synthesis of various layers of spatial evidence derived from various relevant geoscience spatial datasets in order to delineate and rank areas that are prospective for exploration of mineral deposits of the type sought (Bonham-Carter, 1994, Carranza, …
