Abstract. Geological exploration is the process of finding commercially viable mineral resource and the objective is to locate it in the shortest possible time and at the lowest possible cost. The development of exploration technology over a century is briefed along with the emerging challenges for the exploration.

These efforts affect the main fields of geophysics (e.g., ZTEM) and geochemistry (e.g., isotopes), but we also see the emergence of novel exploration methods or revival and redevelopment of established methods. Submissions are invited for a Special Issue of Minerals reflecting on these recent developments. Of particular interest are manuscripts ...

One of the first initiatives was taken by a prospector named R.J. Verbeek, who in 1886 started to promote gold and silver exploration in West Sumatra and the Tapanuli region. He made several efforts to reopen the Salido mine, in which he ffinally succeeded in 1914. However, it was closed again in 1928.

Mineral exploration involves both percussion and rotary drilling that produce rock chips and intact samples of core. The diameter of mineral exploration drill holes (called slimholes) is generally much smaller than the diameter of either petroleum or geothermal wells. Therefore, many of the down-hole tools used for drilling in the petroleum and ...
