Mineral Resource Target Identification
Mapping and Mineral Target Generation
Our process is initiated through the collection of maps and images of the areas of interest and a methodical and deliberate process is followed to generate specific mineral resource targets.
Phase One: Remote Sensing. Several instrument-based techniques are used in the acquisition and measurement of spatially organised data/information on properties (spectral; spatial; physical) where an array of target points within the sensed area correspond to features, objects, and materials consistent with the specific resource. We may typically acquire maps from the Satellite Application Centre in South Africa, managed under the auspices of the Council for Scientific and Industrial Research (CSIR) and assess through various methodologies the nature of a specific surface area.
The orbital and geo-stationary platforms which collect and transmit data from different parts of the electromagnetic spectrum enable us to monitor and define our initial Phase Two indicative map.
Phase Two: Indicative Mapping. A key component of indicative mapping and the identification of geological anomalies is our proprietary methodology of interpreting satellite images, aerial photographs, topographical maps and/or orthographical maps. This methodology was developed from research, practical experience and modern science over a long period of time of successful mineral exploration.
The indicative mapping results are now compared to geological information and the occurrence in that area of the target mineral before proceeding to the next phase.
Phase Three: Target Specific Mapping. We now proceed to enhance the results of the initial mineral mapping to a much higher resolution in within the general selected area. During this process the actual localisation of the anomalies are mapped on target specific maps.
Phase Four: Land Surveyors’ Coordinates. The applicable land surveyors' coordinates of the target areas are now transferred onto the target specific maps to ensure that geophysical surveys are conducted on the exact target areas. This is hugely beneficial to ensure that geophysical surveys are undertaken cost effectively.
Upon achieving the target specific maps and the GPS coordinates, we proceed with the geophysical surveys. TLMR operate state of the art geophysical surveying equipment and conduct its own electromagnetic, magnetic and electrical resistivity surveys and contract in gravity and seismic surveyors when appropriate.
Through computer imaging, the data pertaining to these measurements are enhanced to three dimensional profiles. (See Fig 2 & 3 above) This is followed by the analytical assessment of the three dimensional profiles. These profiles assist in determining the geometry of the subterranean structures as well as the exact locations of future drilling, pitting or trenching.
The enhanced mineral mapping and remote sensing enable us to determine the most feasible site for further exploration from these target specific areas.
Note: Technical aspects of the geophysical surveys are described in Annexure A.
