Highlights Bulk sampling and jig processing at the Jaibaras Project has confirmed that four kimberlite pipes tested to date are diamondiferous with a total of six macro diamonds recovered. Samples collected from the Jaibaras drilling program across the J1, J2 and J4 kimberlite pipes will be submitted for additional caustic fusion and microdiamond analysis in 2018. Recent auger drilling completed at the Riachao Project has confirmed the presence of a 25ha kimberlite pipe at surface. Stage-2 bulk sampling at the Riachao Project has been completed with seven samples being collected for caustic fusion and diamond analysis. Results are expected early in 2018. A detailed ground magnetic survey has commenced at the extended Maravilha Project in Minas Gerais State. A program of bulk sampling will also commence across the M3 kimberlite pipe and other targets identified from the magnetic program. Initial field work is currently planned at the Company’s 100% owned Bacuri Project, in Mato Grosso State, where previous work has identified a diamond bearing kimberlite pipe. JAIBARAS DIAMOND PROJECT, PARA STATE The Jaibaras Diamond Project is located in Para State in Brazil and comprises six individual mineral properties, which in total cover 49,443.47 hectares. To date eight kimberlite targets have been identified at the Jaibaras Project. Bulk sampling and jig processing of the J1, J2, J3 and J4 kimberlite pipes has been completed and has resulted in the recovery of six diamonds from clay weathered kimberlite. The diamonds have good shapes, clarity and colour with two of the six diamonds being yellow. The samples comprise approximately 15t (120t total) of weathered kimberlite collected in a shallow pit that were then washed and concentrated by a jig plant (with a 1mm bottom cut-off). Jig concentrates were then processed by FlowSort X-ray technology, and the ejected material collected and submitted to MSA for diamond collection. Significant problems were experienced in the operating of the jig plant due to the clay content of the kimberlite. The jig plant also produced concentrates with a high white mica con...
