Montesino (Portugal)
North-west Portugal according to the source, Portugal
Other hydrothermalSn
- Type
- Cassiterite vein (surface vein)
Collection sample (G. Treseder) labelled "Montesino", perhaps Montesinho in the Bragança district, without certainty. Ore studied by Williams et al. (2025). Deposit not located: the place cited in the source could not be tied to reliable coordinates.
