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”, “estimates” 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,

2015 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.

Additional GAAP measures that are presented on the face of the Company’s consolidated statements of comprehensive income include “Mine operating costs”, “Earnings from mine operations” and “Earnings from

operations”. These measures are intended to provide an indication of the Company’s mine and operating performance. “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 mineral projects. 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. “Cash operating costs per

ounce”, “total cash costs per ounce” and “all-in sustaining costs per ounce” 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, “cash operating costs per ounce” reflects the cash operating costs

allocated from in-process and dore inventory associated with ounces of gold sold in the period. “Cash operating costs per ounce” may vary from one period to another due to operating efficiencies, waste-to-ore ratios, grade

of ore processed and gold recovery rates in the period. “Total cash costs per ounce” includes “cash operating costs per ounce” plus applicable royalties. Cash operating costs per ounce and 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. 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. For a reconciliation of non-GAAP and GAAP measures,

please refer to Alamos’ Managements’ Discussion and Analysis as presented on SEDAR and the Company’s website.

Notes to Mineral Reserve and Resource Estimates

Notes to Mineral Reserve and Resource Tables:• The Company’s mineral reserves and mineral resource as at December 31, 2015 are classified in accordance with the Canadian Institute of Mining Metallurgy and Petroleum’s “CIM Standards on Mineral

Resources and Reserves, Definition and Guidelines” as per Canadian Securities Administrator’s NI 43-101 requirements. • Mineral resources are not mineral reserves and do not have demonstrated economic viability.• Mineral resources are exclusive of mineral reserves.• Mineral reserve cut-off grade for the Mulatos Mine, the Cerro Pelon Pit and the La Yaqui Pit are determined as a net of process value of $0.10 per tonne for each model block• All Measured, indicated and inferred mineral resources are pit constrained with the exception of the Mulatos Main Pits on the Mulatos property which have no economic restrictions and are tabulated at a

gold cut-off grade of 0.5 grams per tonne.• Mineral Reserve estimates assumed a gold price of $1,250 per ounce and Mineral Resource estimates assumed a gold price of $1,400 per ounce, except as follows: Orion assumed a gold price of $850 per

ounce and a silver price of $13.00 per ounce for resources. Lynn Lake assumed a gold price of $1,550 per ounce with an assumption of the Canadian dollar at parity with the United States dollar. Metal prices, cutoff grades and metallurgical recoveries are set out in the table below.

• El Chanate mineral reserve ounces include a December 31, 2015 inventory of 98,000 recoverable ounces contained within the heap leach pad.• Lynn Lake mineral resources represent 100% of the Lynn Lake Project. Alamos completed the acquisition of Carlisle Goldfields Limited (Lynn Lake Project) on January 7th, 2016.• Orion Mineral Resources are reflected on a 50% basis. Following the completion of a joint venture agreement, Minera Frisco, S.A.B. de C.V. has a 50% interest in the Orion project.
