Mineralisation Footprint Extended at Pitombeiras Vanadium Project
Jangada Mines plc, a natural resources company, is pleased to announce additional positive drill results from the second phase drilling programme at its 100% owned Pitombeiras Vanadium Project (‘Pitombeiras Project’ or the ‘Project’), located in Ceará State, Brazil. The 2,000-metre diamond drilling (‘DD’) programme, which commenced in October 2020, is evaluating the structural corridor associated with the known vanadium titanomagnetite (‘VTM’) mineralisation, including the Pitombeiras North, Pitombeiras South and Goela anomalies.
· Eight holes of nine holes completed to date for a total 649.15 linear metres intersected VTM mineralisation.
· Results recently received include:
o 21.50 metres at 0.55% vanadium pentoxide (‘V2O5’), 9.81% titanium dioxide (‘TiO2’) and 50.39% ferric oxide (‘Fe2O3’), including 7.00 metres at 0.66% V2O5, 12.17% TiO2 and 60.59% Fe2O3
o 27.01 metres at 0.64% V2O5, 11.66% TiO2 and 58.51% Fe2O3, including 11.00 metres at 0.75% V2O5, 14.22% TiO2 and 69.19% Fe2O3
o 27.17 metres at 0.57% V2O5, 10.81% TiO2 and 55.13% Fe2O3, including 9.00 metres at 0.74% V2O5, 14.50% TiO2 and 70.92% Fe2O3
o 22.68 metres at 0.59% V2O5, 11.25% TiO2 and 55.59% Fe2O3, including 7.00 metres at 0.75% V2O5, 14.13% TiO2 and 69.37% Fe2O3
· Drill results further extend mineralisation footprint from previously known resource area in both N-NE and N-NW directions.
Brian McMaster, Executive Chairman of Jangada, said: “Drilling results at the Project continue to deliver positive evidence of the quality of our Pitombeiras Vanadium deposit and again we have seen Pitombeiras North’s orebody footprint extended further north from the existent resource area. This adds to our conviction that Pitombeiras North holds a larger resource to support a robust Preliminary Economic Assessment . VTM mineralisation continues to be opened along strike and will be further drill tested in the current drilling programme. Concomitant to the drilling activities, we are also progressing with all other key aspects of the upcoming Preliminary Economic Assessment , including additional metallurgical tests, logistics and marketing studies, all of which are fully funded to completion.”
Jangada started a new 2000-metre DD programme in October 2020; at the end of 2020, nine drillholes had been completed for a total of 649.15 linear-metres. All the drillholes concluded to date are located on the Pitombeiras North target with the main objective to expand the actual mineral resources. Currently, the Pitombeiras North target has an Indicated Resource of 705,508 tonnes grading 0.62% V2O5 and an Inferred Resource of 1.68 Mt grading 0.60% V2O5 on a high-grade domain with an additional Mineral Resource (Indicated + Inferred) of 2.61 Mt grading 0.40% V2O5 on a low-grade domain.
Recently, the Company received the assay results from an additional four drillholes (DD20PI34, DD20PI35, DD20PI36 and DD20PI37), indicating further northern extension of the known mineralised area as Hole DD20PI37 intercept is located approximately 40 metres away from previously reported drillhole fence.
The four drillholes intersected the vanadiferous titanomagnetite (“VTM”) mineralisation returning an interval of 21.50 metres at 0.55% V2O5, 9.81% TiO2 and 50.39% Fe2O3 on drillhole DD20PI34, 27.01 metres at 0.64% V2O5, 11.66% TiO2 and 58.51% Fe2O3 on drillhole DD20PI35, 27.17 metres at 0.57% V2O5, 10.81% TiO2 and 55.13% Fe2O3 on drillhole DD20PI36 and 22.68 metres at 0.59% V2O5, 11.25% TiO2 and 55.59% Fe2O3 on drill hole DD20P137. Drillhole DD20PI33 returned negative to a final depth of 70.25 metres.
All the mineralised drillholes herein announced reported internal high-grade intersections from 7.00 to 11.00 metres with grades varying from 0.66% V2O5 to 0.75% V2O5, also highlighting the significant Fe2O3 content (Table 1), which reinforces the potential profitability of Pitombeiras’ concentrate at times when iron ore prices hit historical highs.
The results reported in this announcement indicated that the VTM mineralisation extends in both N-NE and N-NW directions and continue to be opened along the strike. The drilling programme restarted in early January 2021 after the Christmas/New Year break and additional drillholes are planned to continually test the Pitombeiras North mineralised area, before moving to the Pitombeiras South and Goela targets.

Preliminary Economic Assessment (‘PEA’)
The second-phase drilling programme is expected to provide the necessary technical information to potentially expand the Company’s initial NI 43-101 mineral resource estimate to support the PEA commissioned with GE21 Consultoria Mineral (‘GE21’).
Additional metallurgical tests have also been commissioned and results are expected in due course. The objective is that, by the time the drilling programme is completed and expanded mineral resources are estimated, metallurgical tests will be readily available for improved accuracy of the PEA.
Other key aspects of the PEA will be the marketing and logistics optionalities, for which Jangada has commissioned market experts to investigate potential buyers of the Company’s products according to the specifications generated by the metallurgical tests.
The current drilling programme, PEA and concomitant project development works will be funded from existing treasury resources.
Quality Assurance & Quality Control
All drill core 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, MnO, Na2O, P2O5, 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 the laboratory. In addition, SGS-Geosol inserts its own standards, blanks and duplicate samples. The results from these control samples indicate acceptable consistency of analysis.
