Rift Valley Resources Limited provided a progress report on the 2017 drilling program at its Cassenha Hill Copper Project in Angola. Drilling activities ceased at the closure of the exploration camp for the rain season in late December 2017. Nine diamond drill holes for 803.5m were completed in the 2017 program. Drilling targeted extensions to a zone of oxide copper mineralization on Cassenha Hill. The mineralized zone is defined by geological mapping, sampling of surface trenches and underground workings, and encouraging intersections from the Company's previous drilling program. The company has now received assay results for the first 6 of the total 9 hole program, which at a 0.25% copper lower grade cut-off include: CDH010: 6m at 0.72% copper from 9m and 6m at 0.51% copper from 48m, CDH013: 5m at 0.57% copper from 15 meters and 3m at 0.94% copper from 32m and 5m at 0.34% copper from 41m. Oxide copper mineralization occurs as azurite and malachite within a sub vertical structural zone of brecciated quartz veining and magnetite-rich alteration bands approximately 20 meters in horizontal width. Significant upside for additional copper mineralization remains as drilling has tested just 400m of the high tenor copper and gold in soils anomaly that extends over a total strike length of 1,700 meters along a zone of quartz-magnetite-barite veining and alteration that can be traced over 4.5 kilometers.
