Vendetta has an option to acquire a 100% interest in the Pegmont lead-zinc-silver deposit located in the Mt. Isa region, Australia, one of the world’s greatest lead-zinc-silver mining areas. Vendetta reported a NI-43-101 compliant mineral resource for Pegmont in February 2014, the sulphide portion of which is presented below (Zones 1-4).

*Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. There is no certainty that any part of the Mineral Resources estimated will be converted into Mineral Reserves estimate

Additionally, 6,505 meters of drilling conducted by Vendetta in 2014, and not included in the aforementioned NI-43-101 resource, resulted in identifying two important new resource extension areas, the Burke Hinge Zone and Zone 5, both of which exhibit higher grade zinc mineralization. The Burke Hinge Zone is shallow and easily accessible for mining, while Zone 5 is slightly deeper and open in two directions. Vendetta’s 2016-2017 drilling program is focused on Zone 5 and the Burke Hinge Zone. Vendetta’s 2014 drilling highlights for these two new higher grade zinc zones are provided below:

2014 Zone 5 Drilling Highlights:

PVRD017           From 242.6 m       4.0 m grading 5.83% Pb and 11.34% Zn PVRD010 From 160.4 m 4.2 m grading 6.29% Pb and 5.64% Zn PVRD013 From 224.8 m 8.8 m grading 8.73% Pb and 3.99% Zn    

2014 Burke Hinge Zone Highlights:

Chris Herald, President and CEO of Solitario commented, “We are delighted to become a significant shareholder of Vendetta. Vendetta’s Pegmont project is a quality asset with outstanding potential for resource growth. It is situated in one of the world’s best mining jurisdictions – North Queensland, Australia. Moreover, the mining infrastructure that exists both locally and regionally allows for expedited development in the future. This investment demonstrates our commitment and belief in the future of the zinc-lead market and strengthens our exposure to this sector. We look forward to assisting Vendetta in their corporate objectives to move this project forward.”

It cannot be assumed that all or any part of an Inferred Mineral Resource will ever be upgraded to a higher category. Under Canadian rules, estimates of Inferred Mineral Resources may not form the basis of feasibility or pre-feasibility studies, except in rare cases.
