Metallurgical Sample UpdateHighlightso Approximately 13 tonnes of PQ core from 5 diamond drill holes has leftLubumbashi for Nagrom Laboratories in Perth via Dar Es Salaamo The locations of the 5 metallurgical drillholes from which the bulk samplehas been harvested, were designed to ensure a good geographicalspread across the bulk of the Roche Dure deposit and that all materialcame from zones of Measured Resource, as identified from theNovember 2018 JORC compliant resource estimateo The sighting of the metallurgical holes was designed to ensure bothweathered material and fresh material was sampled to determine iflithium minerals in the upper weathered zone remain economicallyviableo The tonnage of rock sampled, both fresh and weathered, was calculatedto provide enough final concentrated spodumene representative of theRoche Dure orebody.o Tin and tantalum recoveries, previously unreported in the 2Mtpa ScopingStudy (press release dated 19 November 2018) will be determined andused in the ongoing Feasibility Study to calculate the scale of the likelyreduction in operating costs from the sale of these by-productso Any concentrated spodumene produced from the Nagrom testprogramme will be deemed to be “representative” given thegeographical spread of the sample taken from the central and largestportion of the current Measured Resource of the Roche Dure pegmatitedeposito Parcels of representative spodumene concentrate produced in themetallurgical test programme will be used to determine, at bench scale,if lithium carbonate and lithium hydroxide can be manufactured fromtypical Roche Dure spodumene concentrates and will also be provided topotential off take clients/end users
AVZ’s Managing Director Mr Nigel Ferguson commented: “We are pleased that the 13 tonnes of samplehas been cleared to leave Lubumbashi and will arrive in Perth in time to complete metallurgical test workto be included in the Feasibility Study due later this year. The market will be updated on progress of thesesamples and results as they are received.”AVZ Minerals Limited (ASX: AVZ) is pleased to report that approximately 13 tonnes of whole PQ coresamples has been shipped out of Lubumbashi en-route to Perth for full metallurgical test work.The 5 vertical drill holes (Figure 1) were completed by Equity Drilling in late November 2018 and thencollated and loaded into a container in Lubumbashi for trans-shipment to Nagrom Laboratories in Perthfor full metallurgical test work on optimising recoveries of both lithium (spodumene) and tin andassociated tantalum.Unlike the preliminary metallurgical test work, these samples will be subjected to a full suite of teststhat will allow a complete understanding of how the Roche Dure pegmatite will process through theplanned recovery circuit.Additionally, AVZ will be able to report for the first time, likely recoveries from the 330,000 tonne tinand tantalum JORC compliant resource reported to the market on November 2018.
