Unmanned Aerial Vehicles (UAVs) equipped with geophysical magnetic technologies have emerged as a transformative tool in mining exploration applications. By utilizing these UAVs, surveyors can rapidly and efficiently acquire high-resolution magnetic data over large areas, while maintaining a lower operational risk profile compared to traditional ground or manned aerial surveys. The magnetometers onboard these UAVs are capable of identifying magnetic anomalies associated with various mineral deposits, making this technology a valuable asset in direct detection and structural mapping. Additionally, the ability to safely operate at lower altitudes allows these UAVs to gather detailed magnetic data with greater precision. This use of UAV magnetic technologies in mining exploration not only accelerates data collection but also enhances the quality and accuracy of the acquired geophysical information, thereby contributing to more effective and efficient mineral prospecting.

Electromagnetic (EM) surveys are a versatile and effective geophysical technique used in both exploration and engineering applications. This approach, which measures the response of the subsurface to electric and magnetic fields, allows for the identification of variations in subsurface conductivity. This information is invaluable in delineating ore bodies and hydrocarbon reservoirs, making EM surveys a pivotal tool in mineral and hydrocarbon exploration. Moreover, in engineering contexts, EM surveys provide crucial data on subsurface features, including groundwater presence and contamination zones, which inform the design and risk mitigation strategies for construction projects.

IP – induced polarization

Read More

IP surveys are a crucial tool in the realm of mining exploration, helping to map the subsurface electrical properties of the Earth. This technique can effectively detect disseminated sulphide mineralization and is highly applicable to commodities like gold, graphite, and lithium. For instance, IP surveys have played an essential role in the discovery of several substantial gold deposits by identifying areas of disseminated sulphides associated with gold mineralization. Similarly, in the exploration of graphite and lithium, IP surveys have helped identify zones of potential mineralisation, underlining the technique’s versatility and effectiveness.

Resistivity

Resistivity surveys are a powerful tool for engineering applications, providing valuable insights into the Earth’s subsurface. This technique measures the electrical resistance of different subsurface materials, yielding crucial data that can inform the planning and design of construction and infrastructure projects. Understanding the resistivity of the ground is fundamental in identifying geological hazards, assessing soil composition and stability, locating groundwater and monitoring environmental conditions.

MASW – Multichannel Analysis of Surface Waves

Read More

MASW is a cutting-edge seismic survey technique that is crucial for engineering applications. It involves the analysis of Rayleigh wave velocity distribution, which provides a comprehensive profile of the subsurface shear-wave velocity. This information is invaluable when assessing soil stiffness and identifying different stratigraphic layers, enabling engineers to evaluate site suitability for construction, estimate foundation costs, and plan for potential geological hazards. It can also aid in the detection of voids and groundwater.
