    Astronium graveolens tree - mineral exploration guide in search for copper and potential use of this plant for reforestation of mining waste

    Geological mapping and sampling of sediment-hosted copper-silver mineralization in NE Colombia identified the association of the <i>Astronium graveolens</i> tree (<i>Diomate Gusanero</i>) with the elevated presence of copper (up to 317 ppm) and silver (up to 24 ppm) in plant ash. During the dry season, when most plants lose their leaves, young <i>Astronium graveolens</i> seedlings growing along copper sulfide-rich showings retain their green foliage. This observation allowed authors to effectively use this plant as an exploration guide in search for copper mineralization and <i>Astronium graveolens</i> can be potentially considered as a geobotanical indicator plant. The observed resistance of <i>Astronium graveolens</i> to the presence of copper sulfides suggests that this tree could be also a potential excellent species for reforestation and reclamation of tailings and other mining waste.
