Where a forward-looking statement expresses or implies an expectation or belief as to future events or results, such expectation or belief is expressed in good faith and believed to have a reasonable basis. However, such statements are subject to risks, uncertainties and other factors, which could cause actual results to differ materially from future results expressed, projected or implied by the forward-looking statements. Forward-looking statements often address our expected future business and financial performance and financial condition, and often contain words such as “anticipate,” “intend,” “plan,” “will,” “would,” “estimate,” “expect,” “believe,” “target,” “indicative,” “preliminary,” or “potential.” Forward-looking statements in this communication may include, without limitation: (i) statements relating to Bunker Hill’s planned acquisition of Silver47 and the expected terms, timing and closing of the proposed transaction, including receipt of required approvals and satisfaction of other customary closing conditions; (ii) estimates of future production, including expected annual production range; (iii) estimates of planned expenses and capital expenditures, including the expected costs of construction, commissioning, and operation and the sources of funds to pay for such costs; (iv) estimates of future capital expenditures; (v) estimates of future cost reductions, synergies, including pre-tax synergies, savings and efficiencies; (vi) expectations regarding future exploration and the development, growth and potential of Bunker Hill’s and Silver47’s operations, project pipeline and investments; (vii) expectations of future dividends and returns to shareholders; (viii) expectations of future balance sheet strength and credit ratings; (ix) expectations of future equity and enterprise value; (x) expected listing of common stock on the TSX or any other stock exchange; and (xi) expectations of future plans and benefits. Estimates or expectations of future events or results are based upon certain assumptions, which may prove to be incorrect. Such assumptions, include, but are not limited to: (i) there being no significant change to current geotechnical, metallurgical, hydrological and other physical conditions; (ii) permitting, development, operations and expansion of Bunker Hill’s and Silver47’s operations and projects being consistent with current expectations and mine plans; (iii) political developments in any jurisdiction in which Bunker Hill or Silver47 operates being consistent with its current expectations; (iv) certain exchange rate assumptions for the Canadian dollar to the U.S. dollar; (v) certain price assumptions, including the price of silver; (vi) prices for key supplies being approximately consistent with current levels; (vii) the accuracy of current mineral reserve, mineral resource and mineralized material estimates; and (viii) other planning assumptions. Factors that could cause actual results to differ, and differ materially, include, but are not limited to: Bunker Hill’s ability to consummate the proposed transaction; the occurrence of any event, change or other circumstance that could give rise to the termination of the Arrangement Agreement; failure to obtain applicable regulatory or shareholder approvals in a timely manner or at all; failure to satisfy any other conditions to closing of the proposed transaction; failure to realize the anticipated benefits and synergies of the proposed transaction in the expected timeframe or at all, including as a result of a delay in consummating the proposed transaction; the success of integration plans and the time required to successfully integrate Silver47’s operations with those of Bunker Hill; the focus of management’s time and attention on the proposed transaction and other potential disruptions arising from the proposed transaction; the effects of the announcement of the proposed transaction on Bunker Hill’s or Silver47’s businesses; Bunker Hill’s or Silver47’s ability to retain certain key employees following the public announcement of the proposed transaction; the potential for litigation related to the proposed transaction; Bunker Hill’s or Silver47’s ability to obtain certain third party or governmental regulatory consents, approvals or clearances; potential undisclosed liabilities of Silver47 not identified during the due diligence process; the impact of the proposed transaction on the market price of Bunker Hill’s or Silver47’s common stock and/or operating results; silver and other metals price volatility, currency fluctuations, operational risks, increased production costs and variances in ore grade or recovery rates from those assumed in mining plans, political risk, community relations, conflict resolution governmental regulation and judicial outcomes and other risks; and general economic conditions that are less favorable than expected.

Bunker Hill and Silver47 do not undertake any obligation to release publicly revisions to any “forward-looking statement,” including, without limitation, outlook, to reflect events or circumstances after the date of this communication, or to reflect the occurrence of unanticipated events, except as may be required under applicable securities laws.

Cautionary Note to U.S. Investors Silver47 discloses estimates of “measured,” “indicated,” and “inferred” mineral resources as such terms are used in Canada’s National Instrument 43-101 Standards of Disclosure for Mineral Projects (“NI 43-101”), whereas Bunker Hill’s public disclosures are governed by the Exchange Act, including Regulation S-K 1300 thereunder (“S-K 1300”), in addition to NI 43-101. Although S-K 1300 and NI 43-101 have similar goals in terms of conveying an appropriate level of confidence in the disclosures being reported, they at times embody different approaches or definitions. Consequently, investors are cautioned that public disclosures by Silver47 prepared in accordance with NI 43-101 may not be comparable to similar information made public by companies, including Bunker Hill, subject to S-K 1300 and the other reporting and disclosure requirements under the U.S. federal securities laws and the rules and regulations thereunder.
