Strong assays expand known mineralisationand confirm higher-grade gold & copperzonesOverall grades are consistently in line with large porphyry projectsKey Points
• Strong assays from holes EPDD0012, 13, 14, 15 and 17 from the upper 500m of the ElPalmar target include:
▪ 153.4m at 0.47g/t gold and 0.10% copper from surface in EPDD012 including;
• 33m at 0.92g/t gold and 0.16% copper from 88m▪ 69.0m at 0.39g/t gold and 0.23% copper from 29m in EPDD013
▪ 104.6m at 0.45g/t gold and 0.15% copper from 15m in EPDD014 including;
• 49.8m at 0.67g/t gold and 0.12% copper from 24m
▪ 211m at 0.36g/t gold and 0.15% copper from 198m in EPDD0015 including;
• 35m at 0.49g/t gold and 0.18% copper from 225m
▪ 204.5m at 0.39g/t gold and 0.18% copper from 25.5m in EPDD017 including;
• 121m at 0.46g/t gold and 0.22% copper from 73m
• Drilling is defining higher copper grade domains at >0.2% copper and > 0.35g/t gold (e.g.EPDD013 and 17)
• In hole EPDD019 (assays awaited), native copper has been identified locally withchalcopyrite and bornite
• In hole EPDD020 (assays awaited) copper mineralisation has been identified at depthand further north associated with local strong sheeted quartz veining
• At the Bramaderos Project in southern Ecuador, more assays and initial metallurgicalresults are expected within a fortnight
• Sunstone is well funded with ~A$26m in cash and equities
