Cautionary Note Regarding Forward Looking Information This presentation contains “forward-looking information” within the meaning of Canadian securities legislation and “forward-looking statements” within the meaning of the United States Private Securities Litigation Reform Act of 1995 (collectively, “forward-looking statements”). Forward-looking statements are based on the beliefs, expectations and opinions of management of Trevali Mining Corporation (“Trevali” or the “Company”) as of the date the statements are published, and the Company assumes no obligation to update any forward-looking statement, except as required by law. Forward–looking statements relate to future events or future performance and reflect management’s expectations or beliefs regarding future events including the impacts of the ongoing and evolving COVID–19 pandemic, including but not limited to the effects of COVID–19 on the Company’s business, financial condition and results of operations. Forward-looking statement also include statements with respect to the Company’s growth strategies, expected annual savings from capital projects, anticipated effects of commodity prices on revenues, estimation of mineral reserves and mineral resources, the realization of mineral reserve estimates, the timing and amount of estimated future production, costs of production and capital expenditures, success of mining operations, environmental risks, unanticipated reclamation expenses, title disputes or claims, future anticipated property acquisitions or property dispositions, the content, cost, timing and results of future exploration programs and life of mine expectancies. The potential effects of COVID–19 on the Company’s business are unknown at this time, including the Company’s ability to manage restrictions and other challenges in the jurisdictions in which it operates and continue to safely operate and, in due course, return to normal operating status. The impact of COVID–19 is dependent on many factors outside the Company’s control, including measures taken by public health and government authorities, global economic uncertainties and outlook due to the pandemic, and evolving restrictions relating to mining activities and to travel and transport of goods in certain jurisdictions where the Company operates. In certain cases, forward–looking statements can be identified by the use of words such as “plans”, “expects”, “outlook”, “guidance”, “budget”, “scheduled”, “estimates”, “forecasts”, “intends”, “anticipates” or “believes”, or variations of such words and phrases or statements that certain actions, events or results “may”, “could”, “would”, “might”, “will be taken”, “occur” or “be achieved” or the negative of these terms or comparable terminology. By their very nature, forward–looking statements involve known and unknown risks, uncertainties and other factors which may cause the actual results, performance or achievements of the Company to be materially different from any future results, performance or achievements expressed or implied by the forward–looking statements. Such factors include, among others, risks related to actual results of current exploration activities; changes in project parameters as plans continue to be refined; future prices of zinc, lead, silver and other minerals and the anticipated sensitivity of our financial performance to such prices; possible variations in ore reserves, grade or recoveries; dependence on key personnel; potential conflicts of interest involving our directors and officers; labour pool constraints; labour disputes; availability of infrastructure required for the development of mining projects; delays or inability to

  • btain governmental and regulatory approvals for mining operations or financing or in the completion of development or construction activities; counterparty risks; increased operating and capital costs; foreign currency

exchange rate fluctuations; operating in foreign jurisdictions with risk of changes to governmental regulation; compliance with governmental regulations; compliance with environmental laws and regulations; land reclamation and mine closure obligations; challenges to title or ownership interest of our mineral properties; maintaining ongoing social license to operate; impact of climatic conditions on the Company’s mining

  • perations; risks relating to epidemics or pandemics such as COVID–19 including the impact of COVID–19 on our business, financial condition and results of operations; corruption and bribery; limitations inherent in
  • ur insurance coverage; compliance with financial covenants; our ability to raise capital; competition in the mining industry; our ability to integrate new acquisitions into our operations; cybersecurity threats; litigation;

and other risks of the mining industry including, without limitation, other risks and uncertainties that are more fully described in the “Risks and Uncertainties” section of Trevali's Management's Discussion and Analysis for the three months ended March 31st, 2020 and the “Risk Factors” section of our most recently filed Annual Information Form. Although the Company has attempted to identify important factors that could cause actual actions, events or results to differ materially from those described in forward–looking statements, there may be other factors that cause actions, events or results not to be as anticipated, estimated or intended. Trevali provides no assurance that forward–looking statements will prove to be accurate, as actual results and future events may differ from those anticipated in such statements. Accordingly, readers should not place undue reliance on forward–looking statements. Compliance with NI 43-101 Unless otherwise indicated, Trevali has prepared the technical information in this presentation ("Technical Information") based on information contained in the technical reports, news releases and MD&A's (collectively the "Disclosure Documents") available under the Company’s company profile on SEDAR at www.sedar.com. Each Disclosure Document was prepared by, or under the supervision of, a qualified person (a "Qualified Person") as defined in National Instrument 43-101 Standards of Disclosure for Mineral Projects of the Canadian Securities Administrators ("NI 43-101"). Readers are encouraged to review the full text of the Disclosure Documents which qualifies the Technical Information. Readers are advised that mineral resources that are not mineral reserves do not have demonstrated economic viability. The Disclosure Documents are each intended to be read as a whole, and sections should not be read or relied upon out of context. The Technical Information is subject to the assumptions and qualifications contained in the Disclosure Documents. The disclosure of Technical Information in this presentation was reviewed and approved by Yan Bourassa, P. Geol., Vice President, Exploration and Mineral Resources, a Qualified Person under NI 43-101. Non-IFRS Financial Performance Measures This presentation refers to “EBITDA” (earnings before interest, taxes, depreciation and amortization) and “All-In Sustaining Cost”. These financial performance measures have no standardized meaning under International Financial Reporting Standards (“IFRS”) and are therefore unlikely to be comparable to similar measures presented by other issuers. Management uses these measures internally to evaluate the underlying operating performance of Trevali for the relevant reporting periods. The use of these measures enables management to assess performance trends and to evaluate the results of the underlying business of

  • Trevali. Management understands that certain investors, and others who follow Trevali’s performance, also assess performance in this way. Management believes that these measures reflect Trevali’s performance

and are better indications of its expected performance in future periods. This data is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. For further detail, refer to Trevali’s Management’s Discussion and Analysis for the three months ended March 31st, 2020. Currency All amounts are in US$ unless otherwise indicated.

  • Refined zinc inventories ended 2019 at record lows
  • Seasonal inventory build-up related to Chinese new

year in February has had a modest impact on stocks

  • LME zinc inventories have seen an average daily

change of ~500 kt since December 2019

  • Despite the slight inventory build-up experienced

thus far in 2020, the potential for further zinc mine curtailments precipitated by COVID-19 may lead to concentrate supply shocks and a further reduction to metal inventories, supporting a higher zinc price

high of $310 per tonne in January 2020 to $170 per tonne at the end of June 2020
