(TSXV: VTT) (the \"Company\") is pleased to announce the completion of the Locked Cycle Flotation metallurgical test work at the Pegmont Lead-Zinc Project in Queensland, Australia. These results are from drilling in Zones 2, 3 and the connecting Z Fold.Highlights:Lead Concentrate : 89.7 % to 92.7 % Pb Recovery, 66.3 % to 72.5 % Pb Concentrate GradeZinc Concentrate : 70.4 % to 75.5 % Zn Recovery, 52.3 % to 54.9 % Zn Concentrate GradeTransition Zone material produced a metallurgical performance equivalent to the sulphide zonesThe results highlight that saleable high quality concentrates can be produced for both lead and zinc over the zones tested and that the results are very consistent. Transition Zone material produced a metallurgical performance equivalent to the sulphide zones.Metallurgical testing of the Pegmont Lead-Zinc Mineral Resource has now included sulphide mineralisation from Zones 1, 2, 3 and the Bridge Zone plus transition mineralisation from Zone 1. This complements metallurgical testing of the sulphide mineralisation from the Burke Hinge Zone and Zone 5 lens B and C plus transition mineralisation from Burke Hinge Zone which was conducted at the end of 2016 (see Vendetta news release March 6th 2017, VTT2017 NR#1).Composites were produced from quarter and half NQ and HQ diamond drill core taken from between 2 and 5 drill holes per composite. The objective of the current testing was to confirm the grades and recoveries for both Lead and Zinc concentrates over a broader spread of the Pegmont Mineral Resource, the distribution of the metallurgical samples is shown in Figure 1. For Zones 1, 2 and 3, within the open pit shell, mining dilution was simulated by taking an additional 0.5 m of core from either side of the mineralised zone being tested. For the Bridge Zone the dilution interval was increased to 1.0 m on the hanging wall and 0.5 m on the footwall to reflect the impact of the likely underground mining method, although considered a conservative approach. Composite grades are shown in Table 1.The samples were subjected initially to Open Cycle Flotation testing to establish test condition...
