Bonanza-class gold-Uranium occurrence. Gold ad.3540 g/t.
The Rompas Au–U mineralization is hosted within deformed and metamorphosed calcsilicate veins in mafic volcanics. Dominated by an approximately 6 km long, few tens of meters high, northwest trending ridge consisting of discontinuous outcrops of amphibolite facies metabasalt, dolomite-bearing metasedimentary units, and strongly altered carbonate–albite rocks.
