DRILLING INTERSECTS HIGH GRADE LITHIUM AT PIONEER DOME INCLUDING:
• PDRC114: 19m at 1.77% Li2O from 39m
• PDRC115: 17m at 1.48% Li2O from 35m
• PDRC116: 20m at 2.48% Li2O from 36m
• PDRC112: 31m at 2.54% Li2O from 47m
Perth Western Australia, 20 June 2017: Pioneer Resources Limited ("Company" or "Pioneer", ASX: PIO) is pleased to announce assay results received from the most recent drilling programme at its 100%-held Pioneer Dome Lithium-Caesium-Tantalum (“LCT”) Pegmatite Project, near Norseman in WA.
14 shallow reverse circulation (RC) drill holes (PDRC111-124, totalling 1002m) have intersected the thickest, high grade lithium alumina silicates (refer Figure 2, 3 - likely petalite or spodumene), as well as the thickest lithium mica (e.g. lepidolite) intersections recorded to date from the PEG008A Prospect, adjacent to the Sinclair Caesium Zone. A further 3 diamond core holes, which intersected Sinclair Zone pollucite, have not been cut and assayed as they were drilled for geotechnical information. STRATEGY: ADVANCING THE PIONEER DOME PROJECT Develop Sinclair Zone Pollucite (Caesium) Resource during 2017 The Company’s priority is to expedite the commercialisation the Sinclair Caesium Zone. The next step is the development of an exploration decline and extraction of a bulk sample of ‘direct shipping’ pollucite for metallurgical processing. Current activities and proposed timetable include: • Final submission of the Mine Plan to the Department of Mines and Petroleum so as to enable the extraction of a bulk sample of approximately 5,000t; • Finalisation of an offtake agreement; • Selection of the Mining Contractor and extraction of the bulk sample. Pioneer’s timetable has this completed during the December quarter, 2017; Concurrent with the development of the Sinclair Zone the Company’s activities will include: • Testing Pioneer Dome Lithium Targets focussed towards spodumene deposits. In addition to the PEG008A Lithium Prospect drilling reported here, the Company has identified a further 18 pegmatites with LCT geochemistry responses, that are all drill-ready; • Drill out the Mavis Lake - Fairservice Lithium (spodumene) deposits and commence work at the Raleigh Prospect; • Advance the Cobalt strategy for the extensively mineralised Blair Dome / Golden Ridge Project. THE PIONEER DOME LITHIUM-CAESIUM-TANTALUM SYSTEM Drilling at the Company’s namesake Pioneer Dome Project has confirmed the discovery of a rare-metal Lithium-Caesium-Tantalum Pegmatite system. Drilling has demonstrated highly fractionated pegmatite zonation, including ore grade mineralogical phases. It is well documented that a range of elements, including lithium, caesium, tantalum, rubidium, tin and beryllium, form in distinct zones within the differentiated pegmatite body. The characteristics of PEG008A Pegmatite to date are those of an extreme distal pegmatite zone, which is characterised by the occurrence of pollucite, a globally significant and rare ore mineral of caesium. In this zone lithium may occur in micas (e.g. lepidolite) along with other exotic minerals. Spodumene tends to occur in greater abundance in more proximal pegmatite zones. CAESIUM The key caesium mineral is pollucite, which is very rare. Prior to the discovery of the Sinclair Zone of the Pioneer Dome Project, pollucite had been identified in commercial quantities in only two locations worldwide: the Bernic Lake Mine, Canada, and Bikita Mine, Zimbabwe. Both these have been substantially depleted by mining since the 1990s. The main use of pollucite is in the manufacture of very high value caesium formate brines, used for highpressure/high-temperature oil and gas drilling and exploration. Caesium formate acts to stabilise rock formations, does not cause corrosion of drilling equipment and can enhance hydrocarbon recovery
