Exploration and construction are the starting points of the mining lifecycle. Before a mine can be planned, developed, or expanded, teams need accurate information about the terrain, subsurface mineral indicators, infrastructure limitations, and environmental conditions.

Traditionally, geological prospecting has relied heavily on on-site manual surveys. While this remains an important part of the exploration process, manual methods can be slow, labour-intensive, and limited by large sampling intervals. In many cases, ground magnetic surveys may have low precision, and TPS/GPS data may not accurately reflect the true distribution of subsurface mineral resources.

This becomes even more challenging in harsh or undeveloped environments where mineral resources are often located. Infrastructure may be limited, terrain may be difficult to access, and large areas may need to be investigated before detailed ground verification can take place.

To improve efficiency and reduce manual workload, modern mining teams are increasingly using a combined space-air-ground approach.

Mining exploration teams often face four major challenges: low precision, low efficiency, complex multi-source data, and harsh environments.

Large sampling intervals and low-accuracy ground surveys can make it difficult to identify promising mineral zones with confidence. Manual surveying and GPS/TPS-based data collection can also be slow, especially across large or remote areas.

Surveying and mapping data often comes from multiple sources, making it difficult to integrate, compare, and interpret accurately. At the same time, mineral resources are frequently distributed in undeveloped areas where infrastructure is limited and fieldwork is difficult.

These challenges can delay decision-making and increase the risk of missing important geological indicators.

DJI mining workflows support a more advanced exploration model by combining satellite data, UAV data, LiDAR mapping, and ground validation.

In this workflow, satellite remote sensing is used for large-area exploration, while drones collect higher-resolution data at low altitude. This helps correct and improve the information gathered from satellite sources, especially in areas affected by atmospheric interference, vegetation, terrain shadows, and elevation changes.

A typical integrated workflow may include Landsat-8 for large-area satellite remote sensing, multispectral data, near-infrared data, and thermal infrared data.

The DJI H30T can be used for low-altitude UAV thermal infrared data collection, supporting more precise temperature and radiance information.

The DJI Zenmuse L3 can be used to collect LiDAR point cloud data and generate DEM outputs, helping teams understand terrain structure and elevation in greater detail.

Ground sampling and handheld infrared spectrometry can then be used to validate conclusions and confirm results on site.

This combination allows mining teams to move beyond isolated manual survey points and build a more complete picture of the exploration area.

Satellite emissivity data can be strongly affected by atmospheric conditions and terrain shadows. This can reduce the accuracy of mineral identification, especially in complex terrain.

By using UAVs to collect higher-precision temperature and terrain information at low altitude, teams can correct and improve remote-sensing data. Thermal infrared data from the H30T and LiDAR-derived DEM data from the L3 can help improve the accuracy of vein identification, terrain correction, and mineral exploration outputs.

This makes the final exploration data more reliable and more useful for planning, verification, and decision-making.

Thermal infrared remote sensing can play an important role in vein identification, especially in rare metal mineral resource exploration.

Rare metal deposits, such as tantalum and niobium deposits, can be difficult to locate because they are often small, concealed, or hard to distinguish from ordinary rock. In some cases, the radiation characteristics needed for identification appear only in near-infrared bands, making multi-source data integration essential.

By combining Landsat-8 data, H30T thermal imagery, in-situ spectral data, LiDAR-generated DEM data, and ground sampling, the workflow can help improve the identification of ore-forming veins.

In the China Hutou Mountain example, corrected UAV-supported data was used to identify both known and newly discovered veins. The results showed an identification accuracy of 93%, and compared with traditional manual surveying, twice as many vein distributions were discovered.

For larger and more complex survey areas, DJI drone systems can also be expanded with specialist payloads.

In the example provided, a DJI M400/M350 platform with UFO-CS was used across a 4 km² survey area with an 800 m elevation difference. DSM terrain-following flight was carried out at an 8 m height, with 8 sorties per day used to complete the survey.

The collected data was then processed using aeromagnetic data preprocessing and integrated into ArcGIS Pro. This allowed teams to combine magnetic anomaly maps with 3D models, display magnetic anomaly spatial distribution, and identify correlations with structures and terrain.

High-precision exploration data helps mining teams make stronger decisions from the very beginning of a project.

By combining satellite remote sensing, UAV thermal imaging, LiDAR point clouds, DEM generation, aeromagnetic data, and ground validation, mining teams can improve accuracy, reduce manual effort, and gain a clearer understanding of the site before construction begins.

For exploration and construction, drone technology is not only about capturing images. It is about building a reliable data foundation for planning, verification, safety, and long-term operational success.
