Cautionary Notes

No stock exchange, securities commission or other regulatory authority has approved or disapproved the information contained herein.

Certain statements in this presentation are “forward-looking statements”, including within the meaning of the United States Securities Exchange Act of 1934, as amended. All statements other than statements of historical fact

included in this presentation, including without limitation statements regarding forecast gold production, gold grades, recoveries, waste-to-ore ratios, total cash costs, potential mineralization and reserves, exploration results, and

future plans and objectives of Alamos, are forward-looking statements based on forecasts of future operational or financial results, estimates of amounts not yet determinable and assumptions of management that involve various

risks and uncertainties. Any statements that express or involve discussions with respect to predictions, expectations, beliefs, plans, projections, objectives, assumptions or future events or performance (often, but not always, using

words or phrases such as “expects” or “does not expect”, “is expected”, “anticipates” or “does not anticipate”, “plans”, “est imates” or “intends”, or stating that certain actions, events or results “may”, “could”, “would”, “might” or “will”

be taken, occur or be achieved) are not statements of historical fact and may be “forward-looking statements.” Alamos cautions that forward-looking information involves known and unknown risks, uncertainties and other factors that

may cause Alamos' actual results, performance or achievements to be materially different from those expressed or implied by such information, including, but not limited to, gold and silver price volatility; fluctuations in foreign

exchange rates and interest rates; the impact of any hedging activities; discrepancies between actual and estimated production, between actual and estimated reserves and resources or between actual and estimated metallurgical

recoveries; costs of production; capital expenditure requirements; the costs and timing of construction and development of new deposits; and the success of exploration and permitting activities. In addition, the factors described or

referred to in the section entitled “Risk Factors” in both Alamos Gold Inc.’s Annual Information Form for the year ended December 31, 2016 along with subsequent public filings available on the SEDAR website at www.sedar.com,

should be reviewed in conjunction with the information found in this presentation. Although Alamos has attempted to identify important factors that could cause actual results, performance or achievements to differ materially from

those contained in forward-looking information, there can be other factors that cause results, performance or achievements not to be as anticipated, estimated or intended. There can be no assurance that such information will prove

to be accurate or that management’s expectations or estimates of future developments, circumstances or results will materialize. Accordingly, readers should not place undue reliance on forward-looking information.

Note to U.S. Investors

Alamos prepares its disclosure in accordance with the requirements of securities laws in effect in Canada, which differ from the requirements of U.S. securities laws. Terms relating to mineral resources in this presentation are

defined in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects under the guidelines set out in the Canadian Institute of Mining, Metallurgy, and Petroleum Standards on Mineral Resources and

Mineral Reserves. The United States Securities and Exchange Commission (the “SEC”) permits mining companies, in their filings with the SEC, to disclose only those mineral deposits that a company can economically and legally

extract or produce. Alamos may use certain terms, such as “measured mineral resources”, “indicated mineral resources”, “inferred mineral resources” and “probable mineral reserves” that the SEC does not recognize (these terms

may be used in this presentation and are included in the public filings of Alamos, which have been filed with the SEC and the securities commissions or similar authorities in Canada).

Cautionary non-GAAP Measures and Additional GAAP Measures

Note that for purposes of this section, GAAP refers to IFRS. The Company believes that investors use certain non-GAAP and additional GAAP measures as indicators to assess gold mining companies. They are intended to provide

additional information and should not be considered in isolation or as a substitute for measures of performance prepared with GAAP.

“Cash flow from operating activities before changes in non-cash working capital” is a non-GAAP performance measure that could provide an indication of the Company’s ability to generate cash flows from operations, and is

calculated by adding back the change in non-cash working capital to “Cash provided by (used in) operating activities” as presented on the Company’s consolidated statements of cash flows. “Free cash flow” is a non-GAAP

performance measure that is calculated as cash flows from operations net of cash flows invested in mineral property, plant and equipment and exploration and evaluation assets as presented on the Company’s consolidated

statements of cash flows and that would provide an indication of the Company’s ability to generate cash flows from its minera l projects. “Mine site free cash flow” is a non-GAAP measure which includes cash flow from operating

activities at, less capital expenditures at each mine site. Return on Equity is defined as Earnings from Continuing Operations divided by the average Total Equity for the current and previous year. “Mining cost per tonne of ore” and

“Cost per tonne of ore” are non-GAAP performance measures that could provide an indication of the mining and processing efficiency and effectiveness of the mine. These measures are calculated by dividing the relevant mining

and processing costs and total costs by the tonnes of ore processed in the period. “Cost per tonne of ore” is usually affected by operating efficiencies and waste-to-ore ratios in the period. “Total cash costs per ounce”, “all-in

sustaining costs per ounce”, and “mine-site all-in sustaining costs” as used in this analysis are non-GAAP terms typically used by gold mining companies to assess the level of gross margin available to the Company by subtracting

these costs from the unit price realized during the period. These non-GAAP terms are also used to assess the ability of a mining company to generate cash flow from operations. There may be some variation in the method of

computation of these metrics as determined by the Company compared with other mining companies. In this context, “total cash costs” reflects mining and processing costs allocated from in-process and dore inventory associated

and associated royalties with ounces of gold sold in the period. Total cash costs per ounce are exclusive of exploration costs. “All-in sustaining costs per ounce” include total cash costs, exploration, corporate and administrative,

share based compensation and sustaining capital costs. “Mine-site all-in sustaining costs” include total cash costs, exploration, and sustaining capital costs for the mine-site, but exclude an allocation of corporate and administrative

and share based compensation.

Additional GAAP measures that are presented on the face of the Company’s consolidated statements of comprehensive income and are not meant to be a substitute for other subtotals or totals presented in accordance with IFRS,

but rather should be evaluated in conjunction with such IFRS measures. This includes “Earnings from operations”, which is intended to provide an indication of the Company’s operating performance, and represents the amount of

earnings before net finance income/expense, foreign exchange gain/loss, other income/loss, and income tax expense. Non-GAAP and additional GAAP measures do not have a standardized meaning prescribed under IFRS and

therefore may not be comparable to similar measures presented by other companies. A reconciliation of historical non-GAAP and additional GAAP measures are available at www.alamosgold.com.
