Villasrubias Lithium Project – Spain
ETM holds a 51% interest in the Villasrubias lithium-tantalum exploration project in Castilla y Leon, Spain.
Extensive drilling has been completed at the project, focusing on the Canalita tin mine which ceased production in the 1960s due to the presence of lithium minerals on mine dumps. The main target is a set of lithium-tantalum-niobium-tin-bearing aplite-pegmatite dykes.
Preliminary exploration works performed on the Villasrubias Project include field reconnaissance, grab sampling, geophysics (VLF and tomography) and trenches (259m), which has confirmed the presence of mineralised dykes along at least 370m within a complex buried pegmatite field.
Swordfish Lithium Projects – Spain
The “Swordfish projects” – Aldeadávila, El Payo and Hinojosa – covering lithium, tungsten, tin and gold exploration, cover an area of approximately 126km2 in the region surrounding the Villasrubias Project.
Field planning activities undertaken across these projects include a review of publicly available geoscientific data as well as on-ground geological mapping, ground-truthing of previously defined outcropping rocks, and rock chip sampling for geochemical analysis.
James Bay lithium project – Canada
The Company holds a set of mineral claims in the James Bay region of Quebec in Canada, a premier global hard rock lithium province with numerous active exploration projects and emerging production:
- The Solo Project is located approximately 26km south-east of the Eleonore gold mine base camp within the La Grande sub-province of the Superior Geological Province, southern Eastmain River domain.
- The Good Setting Project is located 47km east of the Eleonore gold mine base camp within the Opinaca sub-province of the Superior Geological Province, which is characterised by paragneiss and migmatites intruded by syn- to post-tectonic intrusions.
Cibeles geothermal research permits – Spain
In May 2026, the Company was awarded five high enthalpy geothermal research permits located to the north of Madrid. The permits are valid for a period of three years, with extensions of three additional years possible under Spanish mining regulations.
