Jangada Mines plc (‘Jangada’ or ‘the Company’), a natural resources company, is pleased to announce additional drilling assay results and report that it has concluded it’s diamond drilling (‘DD’) programme at its Pitombeiras Vanadium Project (‘Pitombeiras’ or ‘the Project’) in Brazil.
The programme evaluated the structural corridor associated with the known vanadium titanomagnetite (‘VTM’) mineralisation, which includes the Pitombeiras North and Pitombeiras South anomalies and the newly discovered Goela VTM targets.
· 19 drill holes have been concluded for a total of 1,360.80 metres
· Two additional assay results received:
o 18.00 metres at 0.49% vanadium pentoxide (‘V2O5’), 10.02% titanium dioxide (‘ TiO2’) and 49.61% ferric oxide (‘Fe2O3’)
o 35.66 metres at 0.56% V2O5, 11.04% TiO2 and 54.39% Fe2O3
· Successfully tested VTM anomaly boundaries and remaining assays for 11 mineralised drill holes to be received in order to complement database for initial JORC mineral resource estimate
Brian McMaster, Chairman of Jangada, said: “We have successfully completed our drilling campaign at Pitombeiras and the diamond drill rig and drilling crew have now been demobilised from the field, which brings us comfort in these challenging times caused by COVID-19. In total, 16 drill holes intersected significant VTM mineralisation and we have seen consistent Vanadium-Titanium-Iron grades and widths from the 9 drill hole assay results we have received so far. Upon receiving the remaining 11 drill hole results, we will be ready to calculate and report our initial JORC mineral resource estimate, followed by a Preliminary Economic Assessment. I would like to thank our exploration team for having accomplished our programme on time and on budget and we look forward to the next phase of development.”
A total of 19 DD holes have been completed for a total of 1,360.80 metres, including 1,058.85 metres at the Pitombeiras North target and 301.95 metres at the Goela target. The drill rig has now been demobilised. 16 from a total of 19 drill holes intersected VTM mineralisation.
Assay results have been received for 5 DD holes, including newly received Hole DD20PI14, which intersected 18.00 meters at 0.49% V2O5, 10.02% TiO2 and 49.61% Fe2O3, and Hole DD20PI16, which intersected 35.66 metres at 0.56% V2O5, 11.04% TiO2 and 54.39% Fe2O3.
With the conclusion of the drilling programme, Jangada has now tested the boundaries of the anomaly as required and, upon receipt of the assay results for the remaining 11 drill holes, the Company will have sufficient data (20 VTM mineralised holes, including 2019 and 2020 drilling) to determine an initial JORC mineral resources estimate and continue with a preliminary economic assessment (‘PEA’), which will be prepared by an independent engineering company to be selected. Both of these activities are to be funded from existing cash resources.
The concluded 2020 drilling programme is a follow-on from the four drill hole campaign executed in 2019. With the addition of the recently received Holes DD20PI14 and DD20PI16, the intersected weighted average grades and widths for all 9 mineralised holes stands at 0.51% V2O5, 10.15% TiO2 and 50.36% Fe2O3 as set out on Table 1 and Figure 1.

Quality Assurance & Quality Control
All drill samples have been prepared and analysed by SGS-Geosol Laboratórios Ltda (‘SGS-Geosol’) based in Belo Horizonte, Brazil. SGS-Geosol is ISO14001:2004 and ISO 9001:2008 accredited and is independent of Jangada. The samples were analysed by fusion with lithium tetraborate-XRF for Al2O3, CaO, Co, Fe2O3, K2O, MgO, Mn, Na2O, P, SiO2, TiO2, V2O5 and retained moisture (LOI) by multi-temperature.
QA/QC procedures include the submission by Jangada of systematic duplicates, blanks and standard samples within every sample batch submitted to SGS. In addition, SGS-Geosol inserts its own standards, blanks and duplicate samples. The results from these control samples indicate acceptable consistency of analysis.
