Cautionary statement Cautionary statement regarding forward looking statements: This presentation contains “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, which are intended to be covered by the safe harbor created by such sections and other applicable laws and “forward-looking information” within the meaning of applicable Canadian securities laws. 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 presentation may include, without limitation: (i) statements relating to Newmont’s planned acquisition of Goldcorp (the “proposed transaction”) and the expected terms, timing and closing of the proposed Newmont Goldcorp transaction, including receipt of required approvals and satisfaction of other customary closing conditions; (iii) estimates of future costs applicable to sales and all-in sustaining costs; (iv) expectations regarding accretion; (v) estimates of future capital expenditures; (vi) estimates of future cost reductions, efficiencies and Newmont Goldcorp synergies, including, without limitation, G&A savings, supply chain efficiencies, full potential improvement, integration opportunities and other improvements and saving; (vii) expectations regarding future exploration and the development, growth and potential of Newmont’s and Goldcorp’s operations, project pipeline and investments, including, without limitation, project returns, expected average internal rate of return, schedule, decision dates, mine life, commercial start, first production, capital average production, average costs and upside potential; (viii) expectations regarding future investments or divestitures; (ix) expectations of future dividends and returns to stockholders; (x) expectations of future free cash flow generation, liquidity, balance sheet strength and credit ratings; (xi) expectations of future equity and enterprise value; (xii) expectations of future plans and benefits; (xiii) expectations regarding future mineralization, including, without limitation, expectations regarding reserves and resources, grade and recoveries; (xiv) estimates of future closure costs and liabilities; and (xv) expectations regarding the Nevada joint venture between Newmont and Barrick, including expectations regarding closing of the joint venture, value accretion, Nevada joint venture synergies and the benefits thereof. 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 Newmont’s and Goldcorp’s operations and projects being consistent with current expectations and mine plans, including, without limitation, receipt of export approvals; (iii) political developments in any jurisdiction in which Newmont and Goldcorp operate being consistent with its current expectations; (iv) certain exchange rate assumptions for the Australian dollar or the Canadian dollar to the U.S. dollar, as well as other exchange rates being approximately consistent with current levels; (v) certain price assumptions for gold, copper, silver, zinc, lead and oil; (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. Risks relating to forward-looking statements in regard to the Newmont’s and Goldcorp’s business and future performance may include, but are not limited to, gold 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. In addition, material risks that could cause actual results to differ from forward-looking statements include: the inherent uncertainty associated with financial or other projections; the prompt and effective integration of Newmont’s and Goldcorp’s businesses and the ability to achieve the anticipated synergies and value-creation contemplated by the proposed Newmont Goldcorp transaction; the risk associated with Newmont’s and Goldcorp’s ability to obtain the approval of the proposed Newmont Goldcorp transaction by their stockholders required to consummate the proposed transaction and the timing of the closing of the proposed transaction, including the risk that the conditions to the transaction are not satisfied on a timely basis or at all and the failure of the transaction to close for any other reason; the risk that a consent or authorization that may be required for the proposed Newmont Goldcorp transaction is not obtained or is obtained subject to conditions that are not anticipated; the outcome of any legal proceedings that may be instituted against the parties and others related to the arrangement agreement; the risk associated with the closing of the Nevada joint venture transaction and ability to achieve the anticipated synergies and value-creation contemplated by the proposed Nevada joint venture transaction; unanticipated difficulties or expenditures relating to the transactions, the response of business partners and retention as a result of the announcement and pendency of the transactions; potential volatility in the price of Newmont common stock due to the proposed transactions; and the diversion of management time on transaction-related issues. For a more detailed discussion of such risks and other factors, see Newmont’s 2018 Annual Report on Form 10-K, filed with the Securities and Exchange Commission (SEC) as well as the Company’s other SEC filings, available on the SEC website or www.newmont.com, Goldcorp’s most recent annual information form as well as Goldcorp’s other filings made with Canadian securities regulatory authorities and available on SEDAR, on the SEC website or www.goldcorp.com.

Appendix

Endnotes Investors are encouraged to read the information contained in this presentation in conjunction with the following notes, the Cautionary Statement on slide 2 and the factors described under the “Risk Factors” section of the Company’s Form 10-K, filed with the SEC on February 21, 2019 and disclosure in the Company’s other recent SEC filings. 1. Projections used in this presentation are considered “forward looking statements”. See cautionary statement above regarding forward-looking statements. Forward-looking information representing post-closing expectations is inherently uncertain. Estimates such as expected accretion, net asset value (NAV), net present value (NPV) creation, synergies, supply chain efficiencies, Full Potential improvements, future production, financial flexibility and balance sheet strength are preliminary in nature. There can be no assurance that the proposed Newmont Goldcorp transaction will close or that the related forward-looking information will prove to be accurate. See cautionary statement on slide 2. Similarly, the proposed Nevada joint venture also remains subject to closing, receipt of governmental approvals, if required, and satisfaction of the conditions of the implementation agreement between Barrick and Newmont. No assurances can be provided that the Nevada joint venture will close or that the related forward-looking information will prove to be accurate. Value creation potential (or NPV creation) as used in this presentation is a management estimate provided for illustrative purposes, and should not be considered a GAAP or non-GAAP financial measure. Value creation potential represents management’s combined estimate of pre-tax synergies, supply chain efficiencies and Full Potential improvements, as a result of the proposed transaction that have been monetized and projected over a twenty year period for purposes of the estimation, applying a discount rate of 5 percent. Such estimates are necessarily imprecise and are based on numerous judgments and assumptions. Expected value creation potential is a “forward-looking statement” subject to risks, uncertainties and other factors which could cause actual value creation to differ from expected value creation. Newmont Goldcorp NAV accretion reflects street consensus and Newmont Goldcorp 2020 accretion reflects street consensus forecast of standalone CFPS and $365M in annual pre-tax synergies and other cost savings and improvements. Full Potential cost savings or improvements as used in this presentation are considered operating measures provided for illustrative purposes, and should not be considered GAAP or non-GAAP financial measures. Full Potential amounts are estimates utilized by management that represent estimated cumulative incremental value realized as a result of Full Potential projects implemented and are based upon both cost savings and efficiencies that have been monetized for purposes of the estimation. Because Full Potential savings/improvements estimates reflect differences between certain actual costs incurred and management estimates of costs that would have been incurred in the absence of the Full Potential program, such estimates are necessarily imprecise and are based on numerous judgments and assumptions. Expected Full Potential cost savings or improvements are projections are “forward-looking statements” subject to risks, uncertainties and other factors which could cause actual results to differ from current expectations. Estimated Nevada joint venture synergies are based upon disclosed Barrick estimates, the NPV of pre-tax synergies were projected by Barrick over a twenty year period, assuming consensus commodity prices and a 5% discount rate. Newmont is not affirming or adopting any statements, disclosures or reports attributed to Barrick. 2. 3. 4. March 2019 Newmont Mining Corporation I Newmont Goldcorp technical update – Slide 24
