CUE ENERGY ANNUAL REPORT 2020 Figure 4: Melonal-Alba-Brama-Playas trend in 3-D magnetics highlighting the potential scale increase to be delivered with more drilling at Bramaderos. The drilling results at Alba and Brama have upgraded the nearby drill targets, and these will see some initial testing during 2022. Other Bramaderos targets Drilling at Limon commenced during June (hole LMDD007 completed to 1,016m in July 2022) and is targeting chargeability and conductivity anomalies defined in the Spartan MT and Orion DCIP surveys, and geological follow-up to previously drilled high-sulphidation mineralisation which returned 59.6m at 0.16% copper, including 13.3m at 0.43% copper and 0.11g/t gold (see ASX announcement 15th October 2019), and stockwork veining in surface trenches which returned 97.6m at 0.71g/t gold and 0.23% copper (see ASX announcement 29th May 2018). Further drilling is planned be undertaken at Limon and complete at least 6 holes for ~3,500m. At Playas the pipe-like magnetic bodies correlate with areas of highest-grade gold and copper in surface samples giving us confidence that drilling will extend that mineralisation to depth. Playas has never been drilled. Melonal, Porotillo and Sandia all present similar relationships. Planning for drilling is underway at Melonal (located southwest of Alba) where at least one hole for ~500m is expected. At Porotillo a historical drill hole (CURI-05) intersected 26m at 1.1g/t gold and 0.2% copper demonstrating that significantly higher grades can be delivered from these systems.
