Desarrollo Agricola y Minero

"In the 1970s the company Holding Company of the Samca Group that owns Daymsa, mined black lignite coal by means of underground and opencast mining methods from their mines in the Valle de Ariño (Teruel) These mines suffered from recurrent and unfortunate sterilization where the coal suddenly transformed into what was disparagingly called “dust”: a black, highly staining coal, that became unpleasantly embedded in skin and nails, and which surprisingly and regrettably did not burn! Following the ancient traditions of farmers in the area that marginally took advantage of this ill-fated “dust” on their farms, where among their specialist crops are the extraordinary Calanda peaches, unique late start peaches with an extraordinary presence and quality. The research started by the geologist and researcher Mr. Joaquín Lahoz paid off, because he managed to profile these powders as belonging to a new mineral, “Leonardite”, with extraordinary properties and agronomic utility, as defined by Dr. Leonard in 1929 in the USA."
