How can LiDAR be used to optimize mineral exploration?

1 Mapping geology

LiDAR can map the geology of an area by measuring the reflected light from a laser beam that is emitted from an airborne or ground-based platform. The laser beam can penetrate the vegetation and soil cover and capture the shape and texture of the underlying rocks and structures. This can help geologists to identify geological features such as faults, folds, fractures, and mineralized zones that are relevant for mineral exploration. LiDAR can also reveal subtle changes in topography and elevation that can indicate the presence of buried deposits or alteration zones.

2 Detecting anomalies

LiDAR can detect anomalies that can indicate potential mineralization by combining the 3D data with other geophysical and geochemical data. For example, LiDAR can measure the reflectance of different wavelengths of light that can indicate the mineral composition of the surface rocks. This can help to identify areas with higher concentrations of certain minerals or metals that can be associated with ore deposits. LiDAR can also detect thermal anomalies that can indicate geothermal activity or hydrothermal alteration that can be related to mineralization. LiDAR can also detect magnetic anomalies that can indicate the presence of iron-rich minerals or rocks that can be associated with ore deposits.

3 Assessing hazards

LiDAR can assess hazards that can affect the safety and feasibility of mineral exploration by providing detailed information on the terrain and environmental conditions. For example, LiDAR can identify potential landslide areas, steep slopes, unstable ground, or water bodies that can pose risks for exploration activities. LiDAR can also monitor changes in the terrain and vegetation over time that can indicate erosion, subsidence, or vegetation stress that can affect the accessibility and sustainability of exploration sites. LiDAR can also provide information on the climate and weather conditions that can influence the planning and execution of exploration activities.

4 Planning operations

LiDAR can plan operations that can optimize the efficiency and effectiveness of mineral exploration by providing accurate and comprehensive data for decision making and resource management. For example, LiDAR can help to select the best locations for exploration drilling, sampling, or surveying by analyzing the terrain, geology, and anomalies. LiDAR can also help to design and optimize the access roads, camps, and infrastructure for exploration activities by evaluating the terrain, environmental, and social factors. LiDAR can also help to estimate the resources and reserves of a mineral deposit by integrating the 3D data with other geological and economic data.
