Aurizon Mines Ltd.

Recommends shareholders REJECT the Alamos Offer

Forward Looking Statements

This presentation contains forward-looking information (as defined in the Securities Act (British Columbia)) and forward-looking statements (collectively, “forward-looking statements”) that are prospective in nature. These statements refer to future events and include information concerning the Alamos Offer and the business operations, prospects and financial performance of Aurizon, which are subject to certain risks, uncertainties and assumptions.

Such forward-looking statements include statements regarding the value of the Company, estimates regarding production, costs of production, capital expenditures, expected recoveries, developments and exploration at Casa Berardi in 2013 as well as future production levels from and value estimates in respect of Casa Berardi, mineral resource estimates and exploration plans and potential in respect of other Company projects, the potential for alternative transactions and the terms thereof and risks relating to Alamos’s properties. All statements other than statements of historical fact may be forward-looking statements. Generally these forward-looking statements can often be identified by the use of forward-looking terminology such as “plans”, “expects” or “does not expect”, “is expected”, “budget”, “scheduled”, “estimates”, “forecasts”, “intends”, “anticipates” or “does not anticipate”, or “believes”, or variations of such words and phrases, or statements that certain actions, events or results “may”, “could”, “would”, “should”, “might” or “will” be taken, occur or be achieved.

These forward-looking statements are based on a number of assumptions, including, but not limited to: assumptions regarding the Alamos Offer and the value of Aurizon’s assets, in particular Casa Berardi; whether or not an alternative transaction superior to the Alamos Offer may emerge; the successful completion of new development projects, planned expansions or other projects within the timelines anticipated and at anticipated production levels; the accuracy of reserve and resource estimates, grades, mine life and cash cost estimates; whether mineral resources can be developed; that pre-production capital costs, operating costs and sustaining and restoration costs will be as estimated; the availability of an experienced workforce and suppliers for the project; that equipment will be available when required and at estimated costs; that the assumptions underlying mineral resource estimates are valid and that no unforeseen accident, fire, ground instability, flooding, labour disruption, equipment failure, metallurgical, environmental or other events that could delay or increase the cost of development will occur; that the results of exploration activities will be consistent with the Company’s expectations; that the current price of and demand for gold will be sustained or will improve; that the supply of gold will remain stable; that the general business, political and economic conditions as well as those specific to the Company’s operations will not change in a material adverse manner; and that financing will be available if and when needed on reasonable terms. Although management of Aurizon believes that the assumptions made and the expectations represented by such statements are reasonable, there can be no assurance that a forward-looking statement herein will prove to be accurate.

Actual results and developments are likely to differ, and may differ materially, from those expressed or implied by the forward-looking statements contained in this presentation and even if such actual results and developments are realized or substantially realized, there can be no assurance that they will have the expected consequences or effects. Factors which could cause actual results to differ materially from current expectations include the availability of any superior alternatives to present to Aurizon Shareholders, whether any such alternative can be sufficiently advanced before the expiry of the Alamos Offer; the risk that some or all of the assumptions on which forward-looking statements are based prove to be invalid including that the cost of labour, equipment or materials, including power, will increase more than expected; that development and production inputs will become less available than expected; that the price of gold will decline; that the Canadian dollar will strengthen against the U.S. dollar; that mineral reserves or mineral resources are not as estimated; that actual costs or actual results of reclamation activities are greater than expected; that actual grades or recovery rates are lower than expected; the risk of unexpected occurrences that affect rates of production, including failure or disruption to plant, process or equipment, labour unrest, unexpected variations in ore reserves, grade or recovery rates and the occurrence of accidents; and the risks set forth in Aurizon’s Annual Information Form dated March 30, 2012 which is available under Aurizon’s profile on SEDAR at www.sedar.com. You should not place undue reliance on any forward-looking statements contained in this presentation.

Aurizon specifically disclaims any obligation to reissue or update these forward-looking statements as a result of new information or events after the date hereof, except as may be required by law. These forward-looking statements should not be relied upon as representing Aurizon’ views as of any date subsequent to the date of this presentation.

Cautionary Statement

CAUTIONARY NOTE TO US READERS

Aurizon is required to describe mineral reserves associated with its properties utilizing Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”) definitions of “proven” or “probable”, which categories of reserves are recognized by Canadian National Instrument 43-101 Standards of Disclosure for Mineral Projects (“NI 43-101”), but which differ from those definitions in the disclosure requirements promulgated by the United States Securities and Exchange Commission (“SEC”) and contained in Industry Guide 7. In addition, under NI 43-101 the Company is required to describe mineral resources associated with its properties utilizing CIM definitions of “measured”, “indicated” or “inferred”, which categories of resources are recognized by Canadian regulations but are not defined terms under Industry Guide 7 and are not permitted to be used in reports and registration statements of United States companies filed with the SEC.

Accordingly, information contained in this presentation regarding our mineral deposits may not be comparable to similar information disclosed by U.S. companies subject to the reporting and disclosure requirements under the United States federal securities laws and the rules and regulations of the SEC thereunder. In particular, this presentation uses the terms “measured” and “indicated” resources. U.S. readers are cautioned that while these terms are recognized and required by Canadian regulations, the SEC does not recognize them. U.S. investors are cautioned not to assume that all or any part of measured mineral resources or indicated mineral resources will ever be converted into mineral reserves.

This presentation also uses the term “inferred” resources. U.S readers are cautioned that while this term is recognized and required by Canadian regulations, the SEC does not recognize it. “Inferred resources” have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies, except in rare cases. U.S. readers are cautioned not to assume that part or all of an inferred resource exists, or is economically or legally mineable.

For additional information regarding reserves and resource information set forth in this presentation, refer to our public filings, including our NI 43-101 technical reports, available on SEDAR at www.sedar.com and on EDGAR at www.sec.gov.

Casa Berardi

2012 production – 136,848 ounces

Tonnes processed – 693,859 at an average grade of 6.8 g/t with recoveries for the year of 90.6%

1,896 tonnes per day underground production rate

Five -seven underground and three surface drill rigs will be active in 2013

Currently in transition phase at Casa Berardi while we are  installing the required infrastructure to commence mining new areas east of the production shaft

These new areas will be the foundation of future underground production at Casa Berardi

Shaft sinking and lateral development out to the 118 and 123  Zones are in progress, and operation is expected to transition from the existing mining areas over the next 18 months

17

Casa Berardi -2013

Commencing its seventh year of production

Operating flexibility will be constrained in the first half of 2013  during the continued shaft sinking and lateral development out to the 118 and 123 Zones

Estimated production of 125,000 – 130,000 ounces of gold in 2013

Average estimated grade of 7.2 grams of gold per tonne

Gold production should gradually increase through the year as more stopes become available and should reach historic levels in the second half

Major shutdowns are planned for 2013, particularly in the first  quarter, in order to switch over to the deepened shaft and incorporate new infrastructure into the mining schedule

Average daily ore throughput is estimated at 1,760 tonnes per day

Mine sequencing in 2013 will result in ore grades that are  expected to be 6% higher than 2012 at approximately 7.2 grams per tonne

Zone 118 is expected to provide ore for the first time in Q3 with an anticipated average grade  in 2013 of approximately 7.9 grams per tonne

18

Casa Berardi-2013

Capital expenditures at Casa Berardi, primarily funded from operating  cash flow, are estimated to total $102.3 million in 2013, comprised of the following:

The Future of Casa Berardi

In a transition phase at Casa Berardi while we install required  infrastructure to start mining the new areas east of the production shaft

These new areas will be the foundation of future production at Casa Berardi

Shaft sinking and lateral development out to the 118 and 123  Zones are in progress and the operation will transition from the existing mining areas over the next 18 months.

Underground Principal area will be developed in 2013

Evaluation of open pit options has been accelerated and will  commence in 2013

During transition, some mining flexibility may be lost. Following  transition, Casa Berardi should return to historical production levels

Paste backfill and wet shotcrete plants will be commissioned in Q2  and Q1-2013
