Vancouver, British Columbia--(Newsfile Corp. - March 5, 2018) - Vendetta Mining Corp. (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 Grade

• Zinc Concentrate : 70.4 % to 75.5 % Zn Recovery, 52.3 % to 54.9 % Zn Concentrate Grade

• Transition Zone material produced a metallurgical performance equivalent to the sulphide zones

The 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 6^th 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 conditions for the Locked Cycle Flotation testing, which provides a better estimation of the likely plant performance under continuous operation with recycling of intermediate grade streams.

The Grade and Recovery performance from the locked cycle flotation testing is shown in Table 1.

Michael Williams, Vendetta's President and CEO commented "The metallurgical results presented here continue to demonstrate the value of the open pit potential in Zone 1, 2 and 3, and of the adjacent Bridge Zone underground target. We are particularly pleased with the performance of the Zone 1 Transition material, with validation of this near surface, low strip material we will look to add additional Transition tonnes as part of the 2018 program."

Impurity analyses for the lead and zinc concentrates are not yet available. The head grades of potential impurity elements are of a similar order as for the composites tested 2016/2017. In the previous round of testing no significant deleterious elements were identified in the concentrates.

The Pegmont sulphide resource is hosted in quartz, garnet, chlorite and magnetite and the sulphide minerals are galena, sphalerite and minor pyrite and pyrrhotite. Optical mineralogy has shown that the majority of the galena and sphalerite are liberated at the primary grind size of p80 passing 106 microns but that there is a minor proportion of finely associated galena and sphalerite composites. These composites require regrinding to finer than 20 microns to achieve satisfactory liberation.

The flotation regime chosen for the selective flotation of the lead and zinc concentrates for the Pegmont composites uses industry standard reagents at usage levels that are typical of many lead-zinc flotation operations. The circuit tested is also industry typical with a roughing stage followed by regrind of the rougher concentrates and then two stages of closed cycle cleaning. The regrind used was 15 and 10 kWh/t for the lead and zinc circuits respectively. The circuit used is shown in Figure 2.

The four sulphide zone composites were subjected to Bond Ball Mill Work Index testing. The results varied from 18.4 to 20.9 kWh/dry metric tonne. This is consistent with the results from Burke Hinge Zone and Zone 5 where results ranged from 16.6 to 19.4 kWh/dry metric tonne. This would place the ore in the medium-hard to hard range.
