Quantification of uncertainty in mineral prospectivity prediction is an important process to support decision making in mineral exploration. Degree of uncertainty can identify level of quality in the prediction. This paper proposes an approach to predict degrees of favourability for gold deposits together with quantification of uncertainty in the prediction. Geographic Information Systems (GIS) data is applied to the integration of ensemble neural networks and interval neutrosophic sets. Three different neural network architectures are used in this paper. The prediction and its uncertainty are represented in the form of truth-membership, indeterminacy-membership, and false-membership values. Two networks are created for each network architecture to predict degrees of favourability for deposit and non deposit, which are represented by truth and false memhership values respectively. Uncertainty or indeterminacy-membership values are estimated from both truth and false membership values. The results obtained using different neural network ensemble techniques are discussed in this paper.
