Sunstone Metals Limited announced that the latest results from its Bramaderos Main deposit in Ecuador provide more evidence that drilling is closing in on the higher-grade areas of the large gold-copper porphyry system. Sunstone holds an 87.5% interest in the Bramaderos property following a recent modification to the JV agreement .Assays from the latest three holes (BMDD004, 5 and 6) include grades of up to 0.93 g/t gold over a 12.15 m interval, 0.57 g/t gold and 0.1% copper over a 127 m interval, and 0.45 g/t gold and 0.18% copper over a 46 m interval. And BMDD007 now underway has already intersected zones of quartz veining and visible chalcopyrite. Assay results from drill holes BMDD004, BMDD005, and BMDD006 have now been received. All holes have intersected intervals of gold and copper. High resolution ground magnetic data has been processed and has undergone further modelling including constrained 3-D modelling. This latest modelling is being integrated with ongoing geological studies. The Bramaderos Main porphyry gold-copper system has been modified by localised post mineral intrusives and faulting, and further drilling and structural studies will further refine the geometry of the system. In ongoing activities at Bramaderos, full analysis of the West Zone target and the epithermal gold targets in the western portion of the concession is nearing completion and will be reported once that process is properly concluded. Drilling at Limon is ongoing and hole LMDD006 is expected to be completed towards the end of January. Surface exploration at Porotillo is continuing. Ground magnetics and geological mapping have been completed. Trenching is being planned to cover areas of partially outcropping porphyry gold-copper mineralisation.
