Advances in Magnetic and Electromagnetic Techniques for Mineral Exploration: Enhancing Resource Discovery, 2nd Edition

Dear Colleagues,

The first edition of this Special Issue, entitled “Advances in Magnetic and Electromagnetic Techniques for Mineral Exploration: Enhancing Resource Discovery”, collated nine papers covering topics from field instrumentation and inversion techniques to applied case histories. Building on this success and in light of recent progress, we are pleased to launch the second edition of this Special Issue and warmly invite new contributions.

Magnetic and electromagnetic methods remain among the most widely applied geophysical techniques in mineral exploration. Their use has advanced significantly with both technological innovations and the rapid growth of computational power. Recent developments include sensor miniaturization, improved system reliability, and the integration of computer-controlled transmitters, receivers, and data acquisition systems. At the same time, artificial intelligence is playing an increasingly important role, particularly in data interpretation.

In practice, airborne electromagnetic surveys are now most often conducted from helicopters, though hybrid approaches combining ground and airborne surveys continue to be tested. Drones are becoming especially popular for magnetic surveys. Three-dimensional inversion has become almost standard for magnetic data, while aeromagnetic interpretation still often relies on two-dimensional filtering techniques. For electromagnetic methods, one-dimensional inversion remains common, although more advanced three-dimensional approaches are emerging.

Recent progress has also been driven by machine learning techniques and improved understanding of the physical properties of mineral targets. This Special Issue provides an opportunity to showcase advances—whether technological, methodological, or conceptual—that enhance the discovery of mineral resources. Submissions are welcome that focus on borehole, ground, and airborne applications of magnetic and electromagnetic methods, as well as from case histories.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Minerals is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
