"Do you speak English - Honey I do". That was the song in the German hit parade almost 50 years ago. A song that conveyed how you can fall in love with more than just the English language. Nothing has changed to this day, except that the "lingua franca" has become more of a professional language than ever before. And as such, it is also playing an increasingly important role in the natural sciences.

As part of its work with "young careers", GREENPEG partner GKZ invited a group of first-year geophysics students led by Ms. Darlene Ann Kilian from the Bergakademie Freiberg to its office to discuss the work of the GKZ and its members, with a particular focus on the GREENPEG project. The project is concerned with optimizing exploration technologies and methods for pegmatites as carriers of important metals for the energy transition. The 10 men and women listened with equal interest to Managing Director Wolfgang Reimer's explanations and his "knowledge of languages" from 30 years of professional life on six continents. - However, he found his sweetheart in Dresden - in Saxon!

GREENPEG project was nominated to the "Research & Innovation Day" at Raw Materials Week in Brussels (RMW) session "Horizon Technology Success Story". Six H2020 projects had the opportunity to present themselves and GREENPEG was the only one dealing with exploration. The project delivers i.a. three technological innovations, which were prioritized in the presentation: The first helicopter-compatible "nose boom magnetometer system" with full EASA certification in Europe, a hyperspectral system based on an "acoustic-optical monochromator" for use with drones, and a newly developed piezoelectric seismograph for direct detection of quartz in the subsurface. The latter is a unique technique for mapping granitic pegmatite in the subsurface.

GREENPEG is now in the final phase and is working on dissemination and marketing of the project results. We started at the biggest EU raw materials event of the year: the EU RMW. Claudia Haase and Marco Brönner from NGU, as our ambassadors, received encouraging feedback from both, industry and academia, on their both presentations.

 GREENPEG presented the new toolset for exploration of buried pegmatites in three talks and two posters during the EU SuperCluster Lapland Geoconference 30 and 31 October 2023 in Rovaniemi, Finland. The clustering event, organized by the Geological Survey of Finland (GTK) and the University of Queensland, Australia, brought together partners of twelve EU projects and a wide range of stakeholders within the raw materials sector. The toolset was well received by the 140 participants and several stakeholders were interested in the GREENPEG toolset application for lithium exploration in Scandinavian exploration sites. One specific topic of discussions with the stakeholders were the maintenance and further improvement of the toolset after the project ending next year underlining the great interest in the GREENPEG innovations. After the conference the GREENPEG caravan moved on to the 14th Fennoscandian Exploration and Mining conference (FEM) held in Levi, Finland.

As an innovation in the EU-funded H-2020 GREENPEG project (GA 869274), the Geological Survey of Norway (NGU) has developed a state-of-the-art piezoelectric seismograph (PE) as a valuable contribution to pegmatite exploration. The instrument utilizes the piezoelectric effect which describes the conversion of mechanical pressure, such as vibration or strain, into electrical energy, or vice versa. This technology has been leveraged to detect quartz, in particular for gold exploration, since the 1970s. NGU applied newest electrotechnology and data acquisition and processing to customize it for granitic pegmatite exploration. The pilot was deployed in different settings e.g. at the GREENPEG demonstration sites in Tysfjord, Norway, and could successfully detect buried quartz deposits, confirmed by drill cores. In the Tysfjord/Drag pegmatite field, the quartz core of the NYF pegmatite (Niobium-Yttrium-Fluorine) was detected at a depth of 5–10 m and underneath a 1-2 m thick quaternary overburden using minimal invasive explosive charges of ca. 100g. At a second site in Tysfjord/Håkonhals the quartz was found at even 15–25 m depth embedded in the host rocks amphibolite and gneisses, while using an 80 kg drop-weight with minimal environmental impact.

Since this novel piezoelectric seismograph is exclusively sensitive to the presence of quartz, it has a much lower ambiguity compared to other geophysical methods applied in pegmatite exploration and is a sustainable and cost-efficient method for this type of exploration, both as a stand-alone method or in combination with other methods on brownfields and greenfields.

 

The conference of the Society of Economic Geologists (SEG), held in London August 26-29 2023 with about 900 participants, addressed the challenges that global exploration and ore deposit research are facing due to accelerated demand and consumption of critical and strategic metals required for the energy transition. The spotlight is on Europe in terms of refined definition of metallogenic domains, development of novel exploration strategies, and re-evaluation of mining potentials. Four GREENPEG partners provided specific solutions how to face the challenges by presenting GREENPEG results including the first public demonstration of the GREENPEG toolset for pegmatite exploration. The feedback and interest in the toolset, which will be published in 2024, was overwhelming underlining the urgent need of improved exploration technologies.

Some partners of the GREENPEG Project Consortium gave support to the media artist Dr Stephen Cornford https://stephencornford.net/ and spent quite some time with him in the field in Tysfjord, Wolfsberg and in Leinster (project demonstration sites) assisting him with questions and guiding him in the field sites. Having visited all three locations, Stephen documented a wide range of the exploration tools and devices used in GREENPEG, recorded some typical scenes of people doing geophysical work and took videos from stills and made sound records such as the internal clicking and beeping of some of the devices. More information will be given in our September issue of GREENPEG Newsletter. See also the video which is now online available for streaming here:

Artist Biography

Stephen Cornford is a media artist who works with consumer electronics, critiquing the ideologies they embody and the constitutive role they have come to play in our lives. His current research is concerned with the toxicity of digital media, the complex metallurgy of ubiquitous technologies and relationships between planetary and photographic space.

Much of his recent work has been made in collaboration with scienctific researchers. He has worked alongside commercial geophysicists prospecting for technology metals in Europe and volcanologists studying magma crystallisation with X-rays. His practice often employs laboratory processes or scientific imaging, using geological furnaces to transform electronic waste or optoelectronics facilities to damage cameras.

Sourcing the European energy transition from domestic resources – vision or wishful thinking?

Sourcing the European energy transition from domestic resources – vision or wishful thinking? This one-day conference questions Europe's raw materials supply security in the context of its economically viable raw material potential and of current geopolitics. It examines the existing and future framework conditions for mining projects and their downstream value chain (regulation, financing, permitting). The question arises, which course do we follow?

The conference also focuses on the work of the European Geological Surveys for the territorial mapping of critical raw materials and highlights the potential for cooperation with Africa. On April 26th, a site visit is offered by United Lithium Corp. to Bergby Lake Lithium exploration project.

Sweden currently holds the EU Council Presidency for the first half of 2023. Sweden is one of the most important mining countries in Europe with great raw material potential for managing the energy and mobility transition and securing the raw material supply for future technologies.

The conference is hosted by the EU HORIZON 2020 project GREENPEG, in cooperation with the Swedish Mining Association SVEMIN and the European Technology Platform on Sustainable Mineral Resources (ETP SMR) and will take place in picturesque city of Uppsala, 20 minutes by train from Stockholm Airport. Participation is free of charge.
