IN MEMORIAM Dr George Colin Stove FBAC PhD BSc (Hons) 13 July 1949 — 20 July 2026
It is with great sadness that we announce the passing of our founder, Dr George Colin Stove, who died suddenly on 20 July 2026, aged 77.
Colin invented Atomic Dielectric Resonance — the technology on which this company was built. Named inventor on three patents, he was the first person in the world to generate deep-penetrating radiowave signals capable of travelling several kilometres through solid ground, and to apply spectroscopic techniques to identify the material beneath. It opened a window into the Earth that had never existed before.
Born into a croft in Sandwick, Shetland, he studied Geography at Aberdeen under Professor R. V. Jones, Churchill's wartime scientific intelligence chief, who set him on the path into radar that would define his life. He went on to pioneer remote sensing at the Macaulay Institute, serving twice as Principal Investigator to the European Space Agency, before inventing ADR and co-founding Adrok with his son Gordon to bring it to the world.
His invention has since been used in mineral, oil, gas and geothermal exploration, in archaeology, and in medicine. As a Geographer to his core, Colin took enormous pride in seeing ADR deployed on every continent on Earth — from the deserts to Antarctica and the Arctic circle.
He was as much an artist as a scientist, and saw no contradiction in that. He had a rare gift for inspiring the people he worked with, and for explaining the most complex ideas so that anyone could understand them. His enthusiasm was infectious, and it shaped everyone who worked alongside him.
Our thoughts are with his family, and with all who had the privilege of knowing him.
Video footage of his celebration of life can be found here.

Company update
Our founding inventor, Dr Colin Stove, has stepped back from his role as Executive Director in order to focus on his health and to care for his wife during a period of illness which was diagnosed in September 2024 when he stepped back from his full-time work commitments at the company.
Colin remains closely connected to the company he helped build and will continue to support the team and our work whenever he is able.
We are very grateful for his leadership, vision and dedication over the years, which have shaped Adrok into the organisation it is today. The Board and wider team fully support Colin and his family at this time. Many of our clients and partners have worked closely with Colin over the years and join us in wishing him and his family well.
The company’s day-to-day operations and strategic direction continue unchanged, and we look forward to Colin’s ongoing involvement in the business.
We kindly ask that Colin and his family’s privacy be respected.

Our Company's founders enjoyed attending and presenting at the enlightening Smeaton300 symposium today at Heriot Watt Univeristy to celebrate 300 years since the birth of John Smeaton (1724–1792), often referred to as the "father of civil engineering".
John Smeaton's contributions to civil engineering were not limited to his technical innovations but extended to establishing the profession's foundations through scientific methods, professional standards, and collaborative efforts. His works and ideas laid the groundwork for modern civil engineering, combining theory with practical application to solve real-world problems.

Density proxy tool developed
Subsurface density can vary significantly based on the type of material (e.g., sand, clay, rock) and its condition (e.g., compacted, saturated with water). Measuring and interpreting these variations helps in numerous scientific and practical applications, as mentioned above. While our ADR technology does not measure density directly in the way geophysical surveys like gravity or seismic methods do, it can provide information from which density-related inferences might be drawn. The dielectric properties, which ADR measures, can be influenced by the material’s density, moisture content, and other physical properties. That said, we have now found a way to directly correlate our ADR measurements with subsurface density proxy measurements.
Subsurface density measurements are critical to a number of geosciences applications such as helping with: resource exploration and extraction; locating and quantifying mineral deposits; designing stable foundations for buildings and tunnels; identifying subsurface contimant plumes for environmental and groundwater studies; and monitoring soil compaction, health and fertility.

Northern Lithium takes a step closer to unlocking critical domestic source of lithium for the UK
Northern Lithium reaches an important new milestone in its programme to produce lithium in the North East of England, with the successful completion of its first exploration borehole and confirmation of the presence of economically viable concentrations of lithium in brines. Against the backdrop of rising demand for electric vehicles (EVs) and ongoing geopolitical instability, today’s announcement puts the UK one step closer to unlocking a secure, low-carbon source of lithium in the North East of England. Adrok are proud to be working with Northern Lithium on this project and helping take another step towards a carbon free future. https://www.northernlithium.co.uk/northern-lithium-takes-a-step-closer-to-unlocking-critical-domestic-source-of-lithium-for-the-uk/

Gensource Potash provides update on the next-stage resource confirmation work with Adrok in its Vanguard Area
With its goal to help bring potash production into the 21st century, Gensource has teamed up with Adrok Ltd. ("ADROK"), to investigate the use of their patented and exclusive Atomic Dielectric Resonance (ADR) imaging technology, for the mapping and delineation of the potash members within the Prairie Evaporite. The main aim for the project is for ADROK to deploy their ADR technology for a proof of concept survey looking at potash deposits, with the aim to establish confidence that ADR can assist Gensource's exploration and resource evaluation efforts. The project included data collection from 13 virtual boreholes ("V-bores").
