Forward-Looking Statements and Disclaimer
Forward-Looking Statements
Certain statements contained in this presentation are forward-looking statements, including within the meaning of the United States Securities Exchange Act of 1934, as amended, and the
rules and regulations promulgated thereunder. All statements other than statements of historical fact included herein, 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 Gold Inc. (“Alamos”), are forward-looking statements that involve various risks and uncertainties. These forward-looking
statements include, but are not limited to, statements with respect to mining and processing of mined ore, achieving projected recovery rates, anticipated production rates and mine life, operating efficiencies, costs and expenditures, changes in
mineral resources and conversion of mineral resources to proven and probable reserves, and other information that is based on forecasts of future operational or financial results, estimates of amounts not yet determinable and assumptions of
management.
Exploration results that include geophysics, sampling, and drill results on wide spacings may not
be indicative of the occurrence of a mineral deposit. Such results do not provide assurance that further work will establish sufficient grade, continuity, metallurgical characteristics and economic potential to be classed as a category of mineral
resource. A mineral resource that is classified as “inferred” or “indicated” has a great amount of uncertainty as to its existence and economic and legal feasibility. It cannot be assumed that any or part of an “indicated
mineral resource” or “inferred mineral resource” will ever be upgraded to a higher category of resource. Investors are cautioned not to assume that all or any part of mineral deposits in these categories will ever be converted into
proven and probable reserves.
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”. Forward-looking statements are subject to a variety of risks and uncertainties that could cause actual
events or results to differ from those reflected in the forward-looking statements.
There can be no assurance
that forward-looking statements will prove to be accurate and actual results and future events could differ materially from those anticipated in such statements. Important factors that could cause actual results to differ materially from
Alamos’ expectations include risks related to the offer, fluctuations in the value of the consideration; integration issues; the effect of the offer on the market price of Alamos common shares; the exercise of dissent rights in connection with
a compulsory acquisition or subsequent acquisition transaction; the liquidity of the Aurizon Mines Ltd. (“Aurizon”) common shares; risks associated with Aurizon becoming a majority-owned subsidiary of Alamos; differences in Aurizon common
shareholder interests; the reliability of the information regarding Aurizon; change of control provisions; risks associated with obtaining governmental and regulatory approvals; failure to maintain effective internal controls; the liquidity of
Alamos common shares on the New York Stock Exchange; and the effect of the offer on non-Canadian holders of Aurizon common shares, and risks related to the on-going business of Alamos, including risks related to international operations; the actual
results of current exploration activities; conclusions of economic evaluations and changes in project parameters as plans continue to be refined as well as future prices of gold and silver, as well as those risk factors described in the section
entitled “Risk Factors Related to the Offer” that is included in Alamos’ take-over bid circular dated January 14, 2013 and in the section entitled “Risk Factors” that is included in Alamos’ annual information form dated
March 29, 2012. Although Alamos has attempted to identify important factors that could cause actual results to differ materially, there may be other factors that cause results not to be as anticipated, estimated or intended. There can be no
assurance that such statements will prove to be accurate as actual results and future events could differ materially from those anticipated in such statements. Accordingly, readers should not place undue reliance on forward-looking statements.
Disclaimers
This presentation is presented in conjunction with Alamos’ Registration Statement on Form F-10 (the “Registration Statement”) and Tender Offer Statement on Schedule TO (the
“Tender Offer Statement”) as filed with the United States Securities and Exchange Commission (the “SEC”). The securities registered pursuant to the Registration Statement are not offered for sale in any jurisdiction in which such
offer or sale is not permitted. You should only rely on the information contained in the offer and circular (the “Offer and Circular”) in each of the Registration Statement and the Tender Offer Statement. The information included in this
presentation is only a summary and you should read the entire Offer and Circular carefully. The Registration Statement and the Tender Offer Statement are available on the SEC’s website at www.sec.gov.
This presentation does not constitute an offer to buy or the solicitation of an offer to sell any of the securities of
Alamos or Aurizon.
Each of Alamos and Aurizon prepare 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 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 and Aurizon 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 each of Alamos and Aurizon, which have been filed with the SEC and the securities
commissions or similar authorities in Canada).

(1) The Company’s mineral reserves as at December 31, 2011 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 National Instrument 43-101 requirements.
(2) Tonnes are rounded to the closest “000s” and grades are rounded to the closest “0.00”s.
(3) The mineral reserve estimate for the Mulatos Mine incorporates the Estrella, Escondida, Puerto del Aire,
El Salto, Mina Vieja, El Victor, and San Carlos areas.
(4) Mineral reserve gold cut-off grade for the Mulatos
Mine is determined as a net of process value of $0.10 per tonne for each model block. The determination was based on an $1,150 per ounce gold price, a December 2011 resource and recovery model, and the 2012 budget costs based on the actual cost
figures from current mining operations.
(5) Pit-contained mineral reserves for the Escondida high-grade zone
are 434,000 tonnes grading 11.81 g/t Au for 164,792 ounces and San Carlos highgrade is 649,000 tonnes grading 7.67g/t Au for 160,043 ounces.
(6) Mineral reserve gold cut-off grade for the La Yaqui Pit is a 0.30 g/t gold. The determination was based on an $800 per ounce gold price, a May 2009 resource model, gold recovery at the
current mining operations, and the 2010 budget costs based on the actual cost figures from current mining operations.
(7) Mineral reserve gold cut-off grade for the Cerro Pelon Pit is determined as a net of process value of $0.10 per tonne, for each model block. The determination was based on an $800 per
ounce gold price, a November 2009 resource model, gold recovery at the current mining operations, and the 2010 budget costs based on the actual cost figures from current mining operations

(1) The economic cut-off grade is 0.2 g/t Au
(2) Measured and indicated resource for the Agi Dagi project (which includes the Baba, Ayitepe, Deli, and Fire Tower zones) and the Kirazli project are pit-constrained, include oxide and
transition material only (no sulphide), with cut-off determined as a net of process value of $0.10 per tonne, for each model block. The determination was based on a US$1,250 per ounce gold price and a US$22.50 per ounce silver price, a March 2012
resource model, average pit slope angle of 38, and estimated costs and recoveries based on Pre-feasibility study specifications. The resources were then tabulated by gold cut-off grade.
(3) Inferred resource for the projects at Kirazli and Agi Dagi (which includes the Baba, Ayitepe, Deli, and Fire Tower
zones) are pit-constrained, include oxide and transition material only (no sulphide), with cut-off determined as a net of process value of $0.10 per tonne, for each model block. The determination was based on a US$1,250 per ounce gold price and a
US$22.50 per ounce silver price, a March 2012 resource model, average pit slope angle of 38, and estimated costs and recoveries based on Pre-feasibility study specifications. Resources were then tabulated by gold cut-off grade. Inferred resources
for the Camyurt project are pit-constrained, using a $1,250 per ounce gold price, a 60:1 Ag:Au value ratio (Au equivalent = Au + ((Ag/60) x Ag recovery)), an average pit slope angle of 45, estimated costs based on the Pre-feasibility study, and
recoveries for Au and Ag based on grade ranges (refer to Table 1 of Alamos press release dated June 28, 2012). Only oxide and transition material (no sulphide) were considered in the pit run.
