Adventus Zinc Enters Into Option Agreement With Salazar Resources on the Curipamba Copper-Zinc-Gold Project and Forms Exploration Alliance in Ecuador

TORONTO, ONTARIO--(Marketwired - Sept. 14, 2017) - Adventus Zinc Corporation ("Adventus") (TSX VENTURE:ADZN) and Salazar Resources Limited ("Salazar") (TSX VENTURE:SRL) are pleased to announce that they have entered into a definitive option agreement (the "Option") whereby Adventus may earn a 75% interest in Salazar's Curipamba Project (the "Project") located in Ecuador by funding exploration and development expenditures of US$25 million over the next five years. A feasibility study is expected to be completed within 3 years, after which Adventus is required to fund 100% of the development and construction expenditures to commercial production.

Adventus and Salazar plan to jointly explore for volcanic massive sulphide ("VMS") as well as hydrothermal gold-silver style deposits within the Project's approximately 21,500 hectare concession area, alongside working on the completion of a feasibility study, which is on the path towards potential future production at the Project. In addition to the Project, both companies are excited to announce that they have also formed an exclusive exploration alliance to explore for additional zinc-related deposits in Ecuador outside of the Project area.

Highlights of the Project

• Project hosts the PEA-stage El Domo deposit. The most recent NI 43-101 El Domo resource released by Salazar consists of an indicated mineral resource of 6.08 Mt grading 2.33% Cu, 3.06% Zn, 0.28% Pb, 2.99 g/t Au and 55.8 g/t Ag and an inferred mineral resource of 3.88 Mt grading 1.56% Cu, 2.19% Zn, 0.16% Pb, 2.03 g/t Au and 42.9 g/t Ag, which can be viewed in the January 16, 2015, "CURIPAMBA PROJECT - EL DOMO DEPOSIT AMENDED AND RESTATED PRELIMINARY ECONOMIC ASSESSMENT CENTRAL ECUADOR," prepared by Gustavo Calvo Martin, M.Sc.A., P. Geo and Adam Johnston, B. Eng, FAusIMM (the "2015 PEA").
  
  
• The 2015 PEA (prior to subsequent positive changes to the mining tax code) outlined an open pit and underground mining project with a 30% IRR (for further particulars, please refer to the 2015 PEA, a copy of which was filed on SEDAR on January 21, 2015). Adventus and Salazar believe significant opportunities exist to grow the size of the Project, while also improving the IRR. The Project is expected to produce separate copper, zinc and lead concentrates, with significant precious metals credits, which will be exported from the port of Guayaquil to international markets. Mineral resources that are not mineral reserves do not have demonstrated economic viability. Mineral resource estimates do not account for mineability, selectivity, mining loss or dilution. The 2015 PEA is preliminary in nature, includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the 2015 PEA will be realized. There is also no certainty that the inferred mineral resources will be converted to measured and indicated categories through further drilling, or into mineral reserves once economic considerations are applied.
