Reference information

Comments This group record includes data for the Almas, Baba-Babuta, Breaza, Hanes-Large, Muncaceasca East, Muncaceasca West, and Trimpoiele prospects; as such, the location information has been generalized. Almas surface sampling by European Goldfields returned one intercept of 63.15 g/t Au over 2 meters. Nine other samples returned values greater than 0.8 g/t Au.
Study area name Europe
