“…The filtered Analytical Signal (AS) allows for the spatial identification of the tw sources producing the observed dipoles. The calculation of AS is based on the executi of directional derivatives, where the obtained anomalies are organized in a bell-sha and where the maxima are located directly on the edges of the anomalous bodies, w their amplitude being proportional to the depth of the location of the magnetic source [2 The map displaying the computed analytical signal (Figure 7) presents a preferent lineation of anomalous areas with an approximate orientation of N80E, coinciding w the two maxima (A and B, Figure 7), and the general trend of the main geological conta and structures, specially, with the normal fault defined through the geological carto raphy of the area (Figure 8). It is important to point out that all the mining works and outcropping mineral sho are located surrounding the northern part of the analytical signal anomalies, with all them situated in the northern block of the normal fault.…”

The use of drones in mining and geological exploration is under rapid development, especially in the field of magnetic field prospection. In part, this is related to the advantages presented for over ground surveys, allowing for high-density data acquisition with low loss of resolution, while being particularly useful in scenarios where vegetation, topography, and access are limiting factors. This work analyzes results of a drone magnetic survey acquired across the old mines of Don Jacobo, where Copper-Cobalt-Nickel stratabound mineralizations were exploited in the Estancias mountain range of the Betic Cordillera, Spain. The survey carried out used a vapor magnetometer installed on a Matrice 600 Pro Hexacopter. Twenty-four parallel survey lines were flown with a speed of 5 m/s, orthogonal to the regional strike of the geological structure, and mineralization with 50 m line separation and 20 m flight height over the ground was studied. The interpretation of the magnetic data allows us to reveal and model two high magnetic susceptibility bodies with residual magnetization, close to the old mines and surface mineral shows. These bodies could be related to potential unexploited mineralized areas whose formation may be related to a normal fault placed to the south of the survey area. Our geophysical survey provides essential data to improve the geological and mining potential of the area, allowing to design future research activities.

“…In the last decade, UAV-borne geophysics has undergone rapid developments (e.g., [1]). Several sensors (geophysical methods such as magnetics, radar, VLF, radiometrics) are now surveyed, in R&D to operational mode, and developments are in fast progress in all parts of the world (e.g., [2,3]), including for emerging methods such as electromagnetism or gravity [4,5].…”

Airborne/UAV Multisensor Surveys Enhance the Geological Mapping and 3D Model of a Pseudo-Skarn Deposit in Ploumanac’h, French Brittany

et al. 2021

Taking advantage of a multi-sensor (multispectral and magnetic) drone survey, we address the detailed geological mapping and modeling of a mineralization in its geological environment. We stress that these high-resolution data allow us to bridge the gap between field observations and a regional aeromagnetic survey. On the one hand, the combination of multispectral imagery with field geological observations enhances detailed geological mapping. On the other hand, the combination of field magnetic susceptibility measurement and their use in detailed to regional magnetic modeling, constrained respectively by UAV-borne and airborne magnetic surveys, allows deriving a model of the mineralization consistent across the scales. This is demonstrated in a case study in a complex polyphased magmatic-metamorphic environment on the coast of French Brittany. The target area hosts a pseudo-skarn mineralization, exhibiting an outstanding magnetic anomaly. The combination of remotely sensed and field data allows deriving a realistic conceptual and geometrical model of the magnetic mineralization in its geological environment, tightly constrained by field observations and measurements.

Improving Aeromagnetic Surveying Capabilities of Uninhabited Aircraft Systems

Uninhabited aircraft systems (UAS) have grown in popularity for aeromagnetic surveying. While the technology has been demonstrated to be viable, studies have not addressed three areas. First, comparisons with traditional platforms over geologically interesting regions are limited. Second, demonstrations of advanced processing with UAS data are rare. And lastly, methods for magnetic compensation of UAS data is outstanding. This thesis addresses these three areas in UAS and machine learning and making time to have regular discussions on my research and providing invaluable guidance in helping me complete my graduate studies. I would also like to thank Mr. David Birkett, Mr. Alan Wood, and the rest of the Stratus Aeronautics Inc. team for organizing and performing the UAS survey work in Nelligan, QC and for providing valuable insight into their UAS. Thank you to Mr. Mark Goldie (IAMGOLD Corporation) for making supporting this project by allowing for the aeromagnetic survey over the Nelligan, QC property as well as taking time to bring me to your Quebec exploration office to discuss details of the property. A big thank you to Mr. Steve Balch for encouraging me to push beyond my perceived limits, mentoring me in all things related to airborne geophysics, and providing me opportunities to gain working experiences in the industry; your guidance and support has been invaluable. And thank you to the Department of Earth Sciences and Carleton University for the support they have provided during my studies. I am grateful for the funding provided for my PhD studies.
