Mining industry professionals are in a constant need of simple and efficient software solutions for drillhole visualization, management, and edition. Although several Open Source solutions are offered to partially fulfill the need, none has propagated into common professional use. In partnership with a team of mining industry leaders including Orano, Evolution Mining, Sandfire Resources, Kenex, the University of Western Australia, NordGold, GoldSpot and the CEA, Oslandia has formed a consortium in 2021 to answer the demand. Oslandia has since then been developing a high performance drillhole data visualization QGIS plugin that combines 3D, cross-section, map, and log views into a fully synchronous system. Moreover, users are able to connect OpenLog directly to their existing drillhole databases such as Acquire, Datashed or Geotic. This talk will succinctly present the functionalities of OpenLog as well as its primary use cases, contribution to QGIS 3D data visualization technology, development roadmap, and future prospects.
