ABSTRACT:Sunstone Metals Limited (ASX:STM) announces that ongoing exploration within the western epithermal gold corridor within its Bramaderos project in Ecuador has defined ten targets for detailed follow-up ahead of drilling. These targets all sit within the Bramaderos epithermal gold corridor (Figures 1 and 2), which is the north-east extension of the gold producing Dynasty Goldfield located 5km to the south-west (held by TSXV listed Core Gold). They include the Bramaderos Vein (Figure 2), where recent trenching returned results of up to 2.1g/t gold and 7.7g/t silver over 0.9m and where historical rock chip sampling returned up to 32.5g/t gold. Other areas of gold mineralisation in rock chip samples include El Espiritu, where there is extensive pathfinder element signature in soil samples. Gold values include 11.63 g/t, 3.70 g/t, 1.80 g/t and 1.615 g/t while silver values include 38.62 g/t, 26.67 g/t, 15.68 g/t and 10.84 g/t. These mineralised samples were collected from barite-bearing ferruginous quartz veins in gullies located approximately 700m northeast of Bramaderos hill, from target B shown in Figure 2. A trenching program is being designed to test this area in a more systematic fashion. A rockchip-sampling program is also being designed to cover 5 of the epithermal targets that have strong pathfinder element signatures in soils but are yet to be surface sampled by rock-chipping. Drilling at West Zone identified anomalous epithermal gold values (Table 1), but on re-interpretation did not test the revised target zones. The main target zone at West Zone is now interpreted to be related to the North Breccia Pod area as a structurally-constrained zone plunging to the east or north-east (Figure 3). Further drill targets have been identified.
