POSITIVE METALLURGICAL TEST WORK RESULTS RECEIVED FOR RECOVERY OF VANADIUM,
NXUU ZINC/LEAD/SILVER/VANADIUM AND GERMANIUM DEPOSIT, BOTSWANA
The Company is pleased to announce that it has now received preliminary results from ALS Laboratories for metallurgical test work conducted for the recovery of Vanadium from the Nxuu deposit.
The results from the two recovery processes tested for Vanadium show that:
Through applying a Direct Flotation process with Hydroxamate, as a collector, 80.4% of Vanadium was recovered to concentrate from sample crushed to 75 µm.
Through applying the process of Wet Table Gravity Separation on a sample crushed to 150 µm, followed by Flotation of the gravity tail crushed to 75 µm, using Hydroxamate, recovered 80.7% of Vanadium to concentrate.
The Company believes that the high Vanadium recoveries obtained from this latest metallurgical test work are very encouraging and further test work will seek to further optimise process performance.
The preliminary Vanadium beneficiation test work was conducted by ALS Laboratories on a composite sample of 53.5 kg from four of the fifteen HQ diamond core holes drilled into the Nxuu Deposit in October/November 2017.
Appendix 1 details the make up of the composite sample used for this metallurgical test-work.
Appendix 2 shows the drill hole plan of the Nxuu Deposit, highlighting the location of the four drill holes, NXDD029, NXDD032, NXDD034 and NXDD046, samples from which were selected to make up the composite as shown in Appendix 1.
Appendix 3 shows the Vanadium and Vanadium Pentoxide intersections and grades of the drill holes shown in Appendix 2.
The composite sample was crushed to 100% passing 0.212 mm and then dry screened over a 0.075 mm screen. The composite sample was first subjected to mineralogical test work (Refer to the announcement released by the Company on 12 December 2018), followed by metallurgical test work which gave the above results.
Forward Looking Statement:
This report contains forward looking statements in respect of the projects being reported on by the Company. Forward looking statements are based on beliefs, opinions, assessments and estimates based on facts and information available to management and/or professional consultants at the time they are formed or made and are, in the opinion of management and/or consultants, applied as reasonably and responsibly as possible as at the time that they are applied.
Any statements in respect of Ore Reserves, Mineral Resources and zones of mineralisation may also be deemed to be forward looking statements in that they contain estimates that the Company believes have been based on reasonable assumptions with respect to the mineralisation that has been found thus far. Exploration targets are conceptual in nature and are formed from projection of the known resource dimensions along strike. The quantity and grade of an exploration target is insufficient to define a Mineral Resource. Forward looking statements are notstatements of historical fact, they are based on reasonable projections and calculations, the ultimate results or outcomes of which may differ materially from those described or incorporated in the forward looking statements. Such differences or changes in circumstances to those described or incorporated in the forward looking statements may arise as a consequence of the variety of risks, uncertainties and other factors relative to the exploration and mining industry and the particular properties in which the Company has an interest.
Such risks, uncertainties and other factors could include but would not necessarily be limited to fluctuations in metals and minerals prices, fluctuations in rates of exchange, changes in government policy and political instability in the countries in which the Company operates.
