Abstract
Exploratory drifts and boreholes are classic methods used in mining when searching for ore. When geology is complicated, workable mineralizations may remain undetected. Attempts to explore for ores using radio waves were made as early as the 1950s. Short-wave electromagnetic radiation is transmitted through the rock. Ore absorbs more energy than the surrounding rock, thus creating a "radio wave shadow" (RWS). The RWS method was developed as a multifrequency method by the BGR to a stage that can be used for routine work. In cooperation with the BBU, this method has been used for underground exploration for lead-zinc ores since 1982. It has proved to be a useful, modern miners tool.
