The first bullet in the section entitled “Summary Term Sheet” in the Offer and Circular under the heading “What are some of the significant conditions of to the Offer?” on page II of the Offer and Circular is hereby deleted in its entirety.

The second and third sentences in the section entitled “Summary Term Sheet” in the Offer and Circular under the heading “Why is Alamos making the Offer?” on page II of the Offer and Circular are hereby deleted in their entirety and replaced with the following:

“Assuming all the other conditions to the Offer are satisfied or waived, it is Alamos’ current intention that, if it takes up and pays for Common Shares deposited under the Offer, it will enter into one or more transactions to enable Alamos to acquire all Common Shares not acquired under the Offer. Alamos currently intends to acquire all of the outstanding Common Shares not tendered under the Offer by the Expiry Time by way of a Compulsory Acquisition or a Subsequent Acquisition Transaction. There is no assurance that such transaction will be completed, in particular if Alamos acquires less than such number of Common Shares which, together with the Common Shares directly or indirectly held by Alamos and its affiliates, represents less than 66  ² / ₃ % of total issued and outstanding Common Shares on a fully diluted basis pursuant to the Offer.”

The section entitled “Summary Term Sheet” in the Offer and Circular under the heading “If I decide not to tender, how will my Common Shares be affected?” on page VI of the Offer and Circular is hereby amended to include the following sentences after the last sentence of the first paragraph:

“Alamos’ ability to effect a Compulsory Acquisition or a Subsequent Acquisition Transaction will be dependent upon the number of Common Shares validly tendered under the Offer and, in particular, whether at least a number of Common Shares are validly tendered under the Offer that, together with the Common Shares directly or indirectly held by Alamos and its affiliates, represents less than 90% or 66  ² / ₃ % of the total issued and outstanding Common Shares on a fully diluted basis. In the event that Alamos acquires less than such number of Common Shares which, together with the Common Shares directly or indirectly held by Alamos and its affiliates, represents less than 66  ² / ₃ % of the total used and outstanding Common Shares on a fully diluted basis, Alamos will evaluate the options available to it at that time and may pursue other means of acquiring, directly or indirectly, all of the Common Shares and other securities exercisable for or convertible or exchangeable into Common Shares in accordance with applicable Law. To the extent that Alamos is not able to acquire 100% of the Common Shares in a timely manner or at all, Alamos’ management believes that it would be able to successfully manage and operate its business with Aurizon as a majority- or minority-owned subsidiary of Alamos and, in these circumstances, Alamos would endeavour to maximize the synergies and overall profitability between the two companies.”

The first sentence in the section entitled “Summary Term Sheet” in the Offer and Circular under the heading “If the Offer is successful will the board of directors and management of Aurizon change?” on page VII of the Offer and Circular is hereby deleted in its entirety and replaced with the following:

“If the Offer is successful and Alamos owns the requisite number of Common Shares to effect such changes, it is anticipated that the current management of Alamos will manage Aurizon in place of Aurizon’s current management, and that the board of directors of Aurizon will be replaced by nominees of Alamos.”

The section entitled “Summary” in the Offer and Circular under the heading “Purpose of the Offer and Alamos’ Plans for Aurizon” on page iv of the Offer and Circular is hereby amended to include the following sentences after the first sentence of the second paragraph:

“Alamos’ ability to effect a Compulsory Acquisition or a Subsequent Acquisition Transaction will be dependent upon the number of Common Shares validly tendered under the Offer and, in particular, whether at least a number of Common Shares are validly tendered under the Offer that, together with the Common Shares directly or indirectly held by Alamos and its affiliates, represents less than 90% or 66  ² / ₃ % of the total issued and outstanding Common Shares on a fully diluted basis. In the event that Alamos acquires less than such number of Common Shares which, together with the Common Shares directly or indirectly held by Alamos and its affiliates, represents less than 66  ² / ₃ % of the total used and outstanding Common Shares on a fully diluted basis, Alamos will evaluate the options available to it at that time and may pursue other means of acquiring, directly or indirectly, all of the Common Shares and other securities exercisable for or convertible or exchangeable into Common Shares in accordance with applicable Law. To the extent that Alamos is not able to acquire 100% of the Common Shares in a timely manner or at all, Alamos’ management believes that it would be able to successfully manage and operate its business with Aurizon as a majority- or minority-owned subsidiary of Alamos and, in these circumstances, Alamos would endeavour to maximize the synergies and overall profitability between the two companies.”

The section entitled “Summary” in the Offer and Circular under the heading “Conditions of the Offer” on page v of the Offer and Circular is hereby deleted in its entirety and replaced with the following:

“Alamos reserves the right to withdraw or terminate the Offer and not take up and pay for any Common Shares deposited under the Offer, or to extend the period of time during which the Offer is open for acceptance and postpone taking up and paying for any Common Shares deposited under the Offer, unless all of the conditions described in Section 4 of the Offer, “Conditions of the Offer”, are satisfied or waived by Alamos on or prior to the Expiry Time. These conditions include, among others, (i) receipt of all governmental or regulatory approvals required to complete the Offer, including any necessary or desirable competition or anti-trust approvals and the expiry of any such applicable waiting periods, and (ii) the absence of any Material Adverse Change in relation to Aurizon. For a complete description of the conditions of the Offer, see Section 4 of the Offer, “Conditions of the Offer”.

The section entitled “The Offer” in the Offer and Circular under the heading “4. Conditions of the Offer” subsection (a) on page 8 of the Offer and Circular is hereby deleted in its entirety.

The section entitled “Circular” in the Offer and Circular under the heading “5. Purpose of the Offer and Alamos’ Plans for Aurizon” subheading “Purpose of the Offer” on page 24 of the Offer and Circular is hereby amended to include the following sentences after the first sentence of the second paragraph:

“Alamos’ ability to effect a Compulsory Acquisition or a Subsequent Acquisition Transaction will be dependent upon the number of Common Shares validly tendered under the Offer and, in particular, whether at least a number of Common Shares are validly tendered under the Offer that, together with the Common Shares directly or indirectly held by Alamos and its affiliates, represents less than 90% or 66  ² / ₃ % of the total issued and outstanding Common Shares on a fully diluted basis. In the event that Alamos acquires less than such number of Common Shares which, together with the Common Shares directly or indirectly held by Alamos and its affiliates, represents less than 66  ² / ₃ % of the total used and outstanding Common Shares on a fully diluted basis, Alamos will evaluate the options available to it at that time and may pursue other means of acquiring, directly or indirectly, all of the Common Shares and other securities exercisable for or convertible or exchangeable into Common Shares in accordance with applicable Law. To the extent that Alamos is not able to acquire 100% of the Common Shares in a timely manner or at all, Alamos’ management believes that it would be able to successfully manage and operate its business with Aurizon as a majority- or minority-owned subsidiary of Alamos and, in these circumstances, Alamos would endeavour to maximize the synergies and overall profitability between the two companies.”

The first sentence of the first paragraph in the section “Circular” in the Offer and Circular under the heading “5. Purpose of the Offer and Alamos’ Plans for Aurizon” subheading “Plans for Aurizon” on page 24 of the Offer and Circular is hereby deleted in its entirety and replaced with the following:

“If the Offer is successful and Alamos owns the requisite number of Common Shares to effect such changes, it is anticipated that the current management of Alamos will manage Aurizon in place of Aurizon’s current management, and that the board of directors of Aurizon will be replaced by nominees of Alamos.”

The first sentence of the first paragraph in the section “Circular” in the Offer and Circular under the heading “15. Acquisition of Common Shares Not Deposited Under the Offer” subheading “Other Alternatives” on page 38 of the Offer and Circular is hereby deleted in its entirety and replaced with the following:

“If, following completion of the Offer, Alamos does not effect a Compulsory Acquisition or a Subsequent Acquisition Transaction, or if Alamos proposes a Subsequent Acquisition Transaction but cannot promptly obtain any required approvals or does not own the requisite number of Common Shares to effect a Compulsory Acquisition or a Subsequent Acquisition Transaction, Alamos will evaluate its other available alternatives.”

The section entitled “Circular” in the Offer and Circular under the heading “15. Acquisition of Common Shares Not Deposited Under the Offer” subheading “Other Alternatives” on page 39 of the Offer and Circular is hereby amended to include the following paragraphs after the first paragraph:

“If the number of Common Shares Alamos takes up and pays for under the Offer, together with the Common Shares directly or indirectly held or controlled by Alamos and its affiliates, represents less than 66  ² / ₃ % of the total issued and outstanding Common Shares on a fully diluted basis, Aurizon could continue as a separate, public company following the completion of the Offer and, depending on the number of Common Shares tendered into the Offer, Alamos may or may not be able to exert significant influence over Aurizon. In such a case, any Shareholders that do not tender into the Offer and remain a Shareholder would be free to vote or dispose of their Common Shares as they see fit in accordance with applicable Law. In these circumstances, certain potential transactions between Alamos and Aurizon would be considered “related party transactions” under applicable Law (specifically, Rule 61-501 and Policy Q-27), which would, unless an exemption is available, require a formal valuation for the transaction and, in addition to any other required securityholder approval, the approval of a majority of the votes cast by “minority” holders of the affected securities, which would include holders other than Alamos and any other person who is a “related party” of Alamos, including an affiliate or an insider of Alamos and any person acting jointly or in concert therewith. The ability to effect such transactions would also be subject to future negotiations between the respective Boards of Directors of Alamos and Aurizon, and in such negotiations, any representatives of Alamos appointed to the Aurizon Board would be precluded from voting on such transactions.

If Alamos were unable to complete a Compulsory Acquisition or a Subsequent Acquisition Transaction in a timely manner or at all, then it would be unable to fully integrate the operations of Alamos and Aurizon and, consequently, unless Alamos is successful in completing one or more “related party transactions” with Aurizon, as described above, Alamos would be limited in its ability to avail itself of Aurizon’s cash flows (other than through pro rata distributions to the Shareholders) and in its ability to effect potential transactions with Aurizon for the purposes of integrating the business and operations of Alamos and Aurizon and, consequently, realizing a significant portion of the synergies otherwise expected to be realized through a combination of Alamos and Aurizon, as described in Section 4 of the Circular, “Reasons to Accept the Offer”. This could materially affect Alamos’ earnings, cash flows and financial condition.”

The section entitled “Circular” in the Offer and Circular under the heading “24. Risk Factors Related to the Offer” subheading “The integration of Alamos and Aurizon may not occur as planned.” on page 60 of the Offer and Circular is hereby amended to include the following sentences after the third sentence:

“If Alamos does not acquire such number of Common Shares, which, together with the Common Shares directly or indirectly held or controlled by Alamos and its affiliates, represents at least 66  ² / ₃ % of the Common Shares and cannot or does not complete a Compulsory Acquisition or Subsequent Acquisition Transaction, it will not be able to control and thereby integrate Aurizon into its business. In such a case, any Shareholders that do not tender into the Offer and remain a Shareholder would be free to vote or dispose of their Common Shares as they see fit in accordance with applicable Law.”

The section entitled “Circular” in the Offer and Circular under the heading “24. Risk Factors Related to the Offer” subheading “After consummation of the Offer, Aurizon could be a majority-owned subsidiary of Alamos and Alamos’ interest could differ from that of the remaining minority Shareholders.” on page 61 of the Offer and Circular is hereby amended as follows:

“After consummation of the Offer and assuming Alamos acquires more than 50% of the Common Shares, Aurizon could be a majority-owned subsidiary of Alamos and Alamos’ interest could differ from that of the remaining minority Shareholders.”

In its press release dated March 5, 2013 and the Second Notice of Extension and Variation, Alamos disclosed that it had received expressions of support for the Offer from certain large shareholders of Aurizon (the “Supportive Shareholders”) after the public announcement of the merger of Aurizon and Hecla. These Supportive Shareholders represented approximately 17.3% of the issued and outstanding Common Shares. None of the Supportive Shareholders are subject to any binding agreements obligating them to tender their Common Shares to the Offer and therefore may choose not to tender into the Offer. Although Alamos has no control as to when a shareholder of Aurizon may decide to tender into the Alamos Offer, Alamos believes that none of the Supportive Shareholders had tendered their Common Shares to the Offer prior to 5:00 p.m. on March 5, 2013, because, in accordance with their fiduciary duties, the interests of their securityholders and market practice, holders typically delay tendering into an offer until shortly prior to the expiration of an offer. It should be noted that any Aurizon shareholders that have or may tender into the Offer continue to have the right to withdraw their tendered shares as set forth in the Offer and Circular.
