The following material has been obtained from a report from the Geological Survey of Victoria (GSV) entitled Gypsum Prospectivity in Northwestern Victoria by Avi Olshina. Gypsum mining is a substantial industry in Victoria, with production valued between $1 million and $4 million per year, depending on tonnage mined and price.
Abstract: Mineral Prospectivity Mapping (MPM) is a multi-step process that ranks a promising target area for more exploration. This is achieved by integrating multiple geoscience datasets using mathematical tools to determine spatial relationships with known mineral occurrences in a GIS environment to produce mineral prospectivity map.
Australia's mineral deposits are described in the AUSIMM monographs on the Geology and Mineral Deposits of Australia and Papua New Guinea. Solomon and Groves (1994, updated 2000) provide a comprehensive synthesis of the geology and origin of Australia's mineral deposits. A summary of the exploration models for major Australia mineral deposit ...

Geoscience Australia's Mineral Potential Mapper is a computer-based system designed to map the nation's potential for new mineral resources. This system has been applied at continental scale to ore deposits containing a combination of nickel (Ni), copper (Cu) and the platinum-group elements (PGEs). It is a decision support system for government ...
Ph.D. Thesis: Mineral Prospectivity Mapping using machine learning algorithms of the Swayze Greenstone Belt and the Abitibi Subprovince Supervisor: Dr. Richard Smith; Thesis committee: Drs. Bruno Lafrance and Daniel Kontak Description: The purpose of my project is to find regions that are favorable for mineral deposits by employing data integration, machine learning techniques
The accuracy of data-driven predictive mineral prospectivity models relies heavily on the training datasets used. These models are usually trained using data for "known" deposit locations as well as "non-deposit" locations that are based on randomly generated point patterns. In this study, data related to the Seabridge Gold Inc Iskut project, an epithermal Au deposit in northwestern ...
Dec 01, 2013· ABSTRACT This paper describes an application of 3D inversion of magnetic data to recover a susceptibility model from magnetic anomalies. For this purpose, the subsurface of the desired area of the magnetic anomaly is divided into a mesh with a large number of rectangular prisms with unknown susceptibilities. A Tikhonov cost function with multi‐term regularizers involving boundaries of ...
This certainly causes bias in the results of mineral prospectivity mapping. If an exploration data set is incomplete but is used, however, to derive a spatial evidence layer and integrated with other spatial evidence layers in order to map mineral prospectivity, a suitable data integration method that allows representation of uncertainty due to ...

In this paper, the radial basis function neural network (RBFNN) is used to generate a prospectivity map for undiscovered copper-rich (Cu) deposits in the Finnmark region, northern Norway. To generate the input data for RBFNN, geological and geophysical data, including up to 86 known mineral occurrences hosted in mafic host-rocks, were combined at different resolutions.

Then, according to the generated anomaly model in the training area, mineral potential mapping (MPM) was performed for the entire study area based on a well …
Theme 2: Real-world utilization of the prospectivity maps in varied fields such as land-use assignments, infrastructure planning and others in addition to mineral deposit exploration. MinProXT 2021 is an open-to-all webinar and we do not charge any participation fee from the attendees.
Copper mining activity is going through big changes due to increasing technological development in the area and the influence of industry 4.0. These changes, produced by technological context and more controls (e.g., environmental controls), are also becoming visible in Chilean mining. New regulations from the Chilean government and changes in the copper mining industry (such as a trend to ...

The model is highly capable of mapping uranium prospectivity because the AUC is greater than 0.5 and close to 1. The prospectivity mapping confirmed that there is significant potential for uranium mineralization in the study area, which opens up new avenues for further explorations on uranium deposits in Pucheng district.
