12 km long segment. Prospects: Blackadder, Waterloo, Brumby, Louisa, Euston, Grand Central, The Gap

The Eastman mafic rocks are dominated by amphibole, clinopyroxene, serpentine and chromite. Amphibole and serpentine likely represent replacement of primary olivine and clinopyroxene. Ilmenite and titanite are common accessory minerals.
