|Zones recommended by the 'Lítio' Working Group|
The Mapa do Minério shows the areas pulled from the Diário da República (DR), where requests and concessions of the Portuguese mining sector are circulated to the public. Also displayed are the zones recommended for prospection and eventual future exploration by the Lithium Working Group in their report published 3/2017 (please see the 'note' below). Considering the areas published in the DR (dre.pt), all kinds of publication types (requests for prospection, cencession contracts, etc.) and minerals (from arsenic to zinc, including lithium, but also more common substances like clay or sand) have been included.

For technical reasons the data extracted from dre.pt may have errors. Processing was done with care, but obviously I cannot assume any responsibility for their correctness. If you have any geo data that should be included or find bugs please contact me at email@example.com. The 9 zones published in the 3/2017 report (ch. IV, p.1) of the 'Lithium' Working Group have been traced manually. The boundaries have thus a mean error of 1-3 km. The coordinates in the publications of dre.pt have been transformed from the national coordinate systems to WGS 84 by using PROJ.4 library, using the geospatial references available on spatialreference.org.
