The present map, focussing on continental Portugal and on the timespan between 2013 and 2023, shows areas extracted from the official gazette Diário da República (DR), where requests and concessions of the mining sector are divulged to the public in a table format. Just select an area to get its details and references to the legal document. In exceptional cases, e.g. when there is no DR record available yet, also other official sources like the repositories of DGEG are considered.
Furthermore, the map shows the areas of the auction of lithium exploration concessions announced by the government since 2017, which were elaborated by the mining authority Direcção Geral de Energia e Geologia (DGEG) between 2018 and 2022. These "six possible areas for public auction" were last published in February 2022 in a low-resolution presentation by the national mining authority DGEG. Previous map versions identified much larger areas: the 2017 Lithium Working Group proposals with a map from the Geological Survey LNEG, 2019 maps released after a parliamentary question by the 'Os Verdes' party in February 2020, and a Shapefile version released during a public consultation in September 2021.
Considering the areas published in DR, all kinds of publication types (requests for exploration, concession contracts, etc.) and minerals (from arsenic to zinc, including lithium, but also aggregates like clay or sand) have been included.

10th version, 9.3.2023
Update of the areas of the Portuguese Government's Lithium Exploration Programme announced since 2017. Reduction of areas after public consultation and update by the mining authority DGEG. Reduced accuracy of +-300m, as the data was only provided as low resolution raster maps even after request.
9th version, 5.10.2021
Lithium Exploration Program areas updated based on the areas published during the public consultation running from 28-09-2021 to 10-11-2021. New section "areas of interest" and category filters to improve map navigation.
8th version, 11.2.2020

For technical reasons the data extracted from DR (dre.pt) may contain errors. Automated processing was done with care, but obviously I cannot assume any responsibility for the data's correctness. If you find any errors in the data or bugs please get in touch at email@example.com. The coordinates in the publications of DR have been transformed from the national coordinate systems to WGS 84 by using PROJ.4 library, using the geospatial references available on spatialreference.org.
