SCOZINC FILES SCOTIA MINE PRE-FEASIBILITY STUDY TECHNICAL REPORT

Halifax, Nova Scotia, July 29, 2020 – ScoZinc Mining Ltd. (TSX-V: SZM) (“ScoZinc” or the “Company”) is pleased

to announce that the National Instrument 43-101 (“NI 43-101”) Scotia Mine Pre-Feasibility Study Technical Report has

been filed on SEDAR (www.sedar.com), pursuant to the news release dated July 7, 2020.

The President and CEO, Mr. Mark Haywood, commented: “Our technical teams and independent experts have worked

tirelessly to deliver the Scotia Mine’s Pre-Feasibility Study Technical Report during the challenges of the COVID -19

Pandemic. ScoZinc is particula rly pleased with the robust results and compelling economics which this NI 43 -101

Technical Report demonstrates. The relatively low-capital requirement of $30.8 million, short commercial production

time-frame of 9 to 12 months, and 14-year mine life at an average cash cost of US$0.59/lb combine to make our Scotia

Mine potentially one of the most attractive Canadian mining investment opportunities in the market place today with a

2.4 year payback, $335 million pre-tax cash flow and an after-tax Internal Rate of Return of 49%.”

There can be no assurance that forward-looking statements will prove to be accurate and actual results and future events

could differ materially from those anticipated in such statements. Important factors that could cause actual results to differ

materially from ScoZinc’s expectations include, among others, the degree to which mineral resource and reserve estimates

are reflective of actual mineral resources and reserves, the degree to which factors which would make a mineral deposit

commercially viable are present, the price of zinc and lead, uncertainties relating to availability and costs of financing needed

in the future, changes in equity markets, risks related to international operations, the actual results of current exploration

activities, delays in the development of projects, conclusions of economic evaluations and changes in project parameters as

plans continue to be refined as well as future prices of metals, ability to predict or counteract potential impact of COVID-

19 coronavirus on factors relevant to the Company’s business, as well as those factors discussed in the section entitled “Risk

Factors” in ScoZinc’s Management’s Discussion and Analysis. Although ScoZinc has attempted to identify important
