Quantitative assessment of geological risk otherwise known as prospectivity modelling/analysis or potential mapping has been around since the early 1990’s.
The aim of prospectivity analysis is to de-risk exploration decision making using large geospatial datasets and the latest mineral systems knowledge. This allows the quantitative assessment of geology, geochemistry and geophysical data to identify areas of economic mineral potential within an area, region or country.
Techniques employed for this analysis include a manual GIS approach and more statistical methods such as Weights of Evidence, Fuzzy Logic and Neural Networks.
Our products are produced using a knowledge led GIS approach utalising mineral deposit model criteria we have built for over 50 deposit types.
This allows us/the system to analysis geological data without statistics, training data or assigning empirical weights, ideal for regional studies or areas with little previous exploration.
Our outputs are also very transparent, with the areas identified clearly attributed with if the geological criteria is met Yes/No/Present/Not Present.
