- Mineral prospectivity mapping for critical raw materials at the European scale with the CBA method [Resumo]Publication . Bertrand, Guillaume; Sadeghi, Martiya; De Oliveira, Daniel Pipa Soares; Tourlière, B.; Arvanitidis, Nikolaos; Gautneb, Håvard; Gloaguen, Eric; Törmänen, Tuomo; Reginiussen, Helge; Decree, Sophie; Pereira, Aurete; Quental, LídiaABSTRACT: This contribution presents pan-European prospectivity maps for lithium, cobalt, natural graphite, niobium, tantalum, phosphates and rare earth elements that were produced by the GeoERA FRAME project. These maps are based on the cell-based association (CBA) method, which was specifically developed for mineral prospectivity mapping at regional to continental scales. The purpose of this method is to address issues such as uncertainties in the location of cartographic objects and the need to consider geological contexts. Several options to calculate favourability scores were statistically tested and compared to improve the accuracy of the method and produce the final maps.

Data has been compiled on mineral occurrences and mineral provinces across Europe, in particular, areas with potential to host Critical Raw Materials. Anecdotal evidence from the minerals sector provides an indication of the likelihood of exploration leading to mine development. For every 1,000 mineral showings examined, only 100 may receive further exploration work and of those 100, only 10 may warrant more detailed sampling either through trenching, drilling or other means and of those 10 only 1 may proceed to an evaluation through a full feasibility study which itself has only 50% chance of being positive. Following this, any project for which a mine proposal is made must undergo a full evaluation and permitting by authorities including full public consultation. The proposal may or may not pass this scrutiny. In terms of a schedule, the generally accepted minimum time frame from discovery to production is 10 years and usually much more, up to 20 years.
- Prospectivity maps of critical raw materials in Europe : DELIVERABLE D3.5Publication . Bertrand, Guillaume; Sadeghi, Martiya; Arvanitidis, Nikolaos; de Oliveira, Daniel Pipa Soares; Gautneb, Håvard; Gloaguen, Eric; Törmänen, Tuomo; Reginiussen, Helge; Decree, Sophie; Pereira, Aurete; Quental, LídiaABSTRACT: The present report describes the mineral prospectivity maps that were produced by the work package (WP) 3 of the FRAME project. These prospectivity maps assess the favourability in Europe, at continental scale, for lithium, cobalt, natural graphite, phosphate, niobium, tantalum and rare earth elements. They are based on datasets produced by the FRAME project (WP4 for phosphate, WP5 for lithium, cobalt and graphite, and WP6 for niobium and tantalum) and by the former EURARE project for rare earth elements.
