Remote Sensing in Mineral Exploration

Remote sensing is the science of acquiring, processing, and interpreting images and related data, acquired from aircraft and satellites, that record the interaction between matter and electromagnetic energy (Sabins, 1997, p. 1). Understand geological processes and overcome exploration challenges through structural interpretation of remote sensing data.

We interpret remotely sensed data using a sound structural geological understanding to provide informed, integrated interpretations that can be directly applied to exploration targeting.

Our global team of multi-skilled geological experts assimilates complex data sets to generate and refine targets, define controls on mineralisation, and delineate prospective structures and sequences. Integrating the data with our geological and structural knowledge enables us to identify geological processes, detect structures, and assess the likelihood of ore deposit accumulation. Critical to this, is evaluating the timing of mineralisation within an area's tectonic history. This allows us to immediately define prospective targets that would not otherwise be defined, through direct detection methods.

We specialize in developing process-driven conceptual models to identify and improve the understanding of your mineral targets. By using multiple data sets, our highly experienced geologists solve geological ambiguities not resolvable with a single data set.

Highlights :

  • Interpretation of aeromagnetic and satellite imagery data to produce structural and geological maps that help target deposits
  • Ranking of exploration targets for specific deposit styles or commodities
  • Interpretation of 2D and 3D seismic data and integration with aeromagnetic interpretations to produce 3D models of basement architecture
  • Production of interactive GIS maps and models that clients can update over time
  • Customized, on-site, geophysical interpretation courses that train exploration geologists on the geological interpretation of geophysical data

Purpose

These studies aims to give an oversight of what is being done by researchers in GIS and remote sensing (field) to explore minerals.

Design/methodology/approach

The approach of this type of study used to generate the thematic maps with the aid of application of GIS and remote sensing techniques for mineral exploration with help of different soft wares.

Findings

When applied alone, each technique seems effective, but it is important to know that combining different methods is more effective in identifying ore deposits.

Originality/value

  • These studies provide possible solutions to both current and future perspective issues relating to the application of GIS and remote sensing to mineral exploration.
  • Our state of the art LIDAR and Photogrammetry mapping drones can deliver precision mapping at as little as 1cm GSD (ground sampling distance) and with real world accuracy as low as 2 cm XY and 3 cm Z.
