News & Innovations

DESMEX II airborne electromagnetic methods for deep exploration
DESMEX aims at developing airborne electromagnetic (EM) methods for deep exploration of mineral deposits. We focus on the implementation of the semi-airborne EM technique. Our efforts comprise the development of novel magnetic field sensors, data processing techniques and modelling and inversion codes. Dedicated sites in Germany, Europe and worldwide are investigated in case studies to demonstrate the technologies.
DESMEX has commenced in 2015. Recently, the continuation project DESMEX II was launched. DESMEX II includes both manned helicopter and unmanned drone operations. We also aim at demonstration surveys at real-world cases to bring the technologies closer to application.


funded by: Bundesministerium für Bildung und Forschung BMBF
HIRIP – High Resolution Resistivity and Induced Polarisation is methodology combining classic Pole-Dipole and advanced multi-electrode measurements. - 10 times higher data density compared with Pole-Dipole resulting in better modelling of the data by using full wave data up to a depth of 500m.
This hybrid EM resistivity technique is effective in delineating targets ranging from super-conductive Ni sulphides to poorly conductive (100 - 1000 Ohm.m) sulphide or pregnant/target lithologies. Depths of penetration uo to 1500m .
