The class of equity securities to which this Statement on Schedule 13D relates is the common stock (“Common Shares”) and warrants over Common Stock, of Brigus Gold Corporation, formerly known as Apollo Gold Corporation. (“Brigus,” or the “Issuer”), a Yukon Territory, Canadian corporation having its principal executive offices at 1969 Upper Water Street, Suite 2001, Halifax, Nova Scotia, B3J 3R7 Canada.

This statement on Schedule 13D is being filed by Macquarie Bank Limited (“MBL”), an Australian corporation.  MBL is a global provider of banking, financial, advisory, investment and funds management services. MBL has its principal office at 1 Martin Place, Sydney, NSW 2000, Australia.

Macquarie B.H. Pty Limited is the sole voting member of MBL.  Macquarie B.H. Pty Limited is directly and wholly-owned by MGL, which is listed on the Australian Securities Exchange (ASX). MGL is a leading provider of banking, financial, advisory, investment and funds management services. MGL has its principal office at Level 7, 1 Martin Place, Sydney, NSW 2000, Australia.  MGL’s ownership of MBL is through Macquarie B.H. Pty Ltd, its wholly owned subsidiary which has no other business activities other than the ownership of MBL. As a result, the information provided is only for MGL and MBL.

The directors and executive officers of MGL and MBL are set forth on Schedule I attached hereto.  Schedule I sets forth the following information with respect to each such person:

(i) name;

(ii) business address;

(iii) present principal occupation or employment and the name, principal business and address of any corporation or other organization in which such employment is conducted; and

(iv) citizenship.

During the last five years, none of MGL, MBL or any person named in Schedule I, has been (i) convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or (ii) a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

In July 2008, MBL participated in a Prospectus Offering of units. On July 23, 2008, MBL acquired, for US$0.50 per unit (Cdn$ 0.50, as of July 23, 2008), 4,000,000 units from the Issuer, each unit comprising of 1 Common Share and half of one warrant each convertible into an equivalent Common Share.  This resulted in MBL holding 4,000,000 Common Shares of Apollo,

4

and 2,000,000 warrants exercisable to purchase 2,000,000 Common Shares at US$0.65 (Cdn$0.65, as of July 23, 2008) per Common Share.

On December 10, 2008, the Issuer entered into a US$15,000,000 bridge loan facility with MBL and another lender.  As part of this facility, MBL made available 50% of the aggregate loan and received 21,307,127 warrants, each warrant entitling MBL to purchase one Common Share at a price of US$0.177 (Cdn$0.221, as of Dec. 10, 2008) per Common Share and exercisable for a four year period ending on December 10, 2012.  The terms of the warrant are contained within the Warrant Certificate dated December10, 2008, issued by Apollo to MBL (“2008 Warrant”).

On February 23, 2009, the Issuer entered into a US$ 70,000,000 project financing facility with MBL and another lender that was used to repay the above-referenced bridge loan facility.  In connection therewith, Macquarie was issued 23,198,336 warrants exercisable for a period of 48 months from closing, each warrant entitling MBL to purchase one Common Share at an exercise price of US$ 0.20 per Common Share (Cdn$ 0.252, as of February 23, 2009).  The terms of the warrant are contained within the Warrant Certificate dated February 20, 2009, issued by Apollo to MBL (“2009 Warrant”).

As part of a transaction involving a business combination between Brigus Gold Corp and Linear Gold Corp, on June 24, 2010, Brigus’s shareholders authorized it to affect a 1-for-4 reverse split of the number of shares of the Company's common stock (the “Reverse Split”).  In connection with the transaction, MBL entered into an agreement (“Lock Up Agreement”) with Brigus and Linear pursuant to which MBL agreed not to, directly or indirectly, sell, assign, transfer, loan, grant security over, grant any warrant, right or option to purchase, make any short sale or otherwise dispose of, or enter into any hedging transactions with respect to the Common Shares in Brigus, or any options or warrants to purchase any Common Shares in Brigus held by MBL before December 31, 2010.

On November 18, 2010 the Lock Up Agreement was terminated effective November 18, 2010.

MBL intends to hold the Common Shares, including the warrants and Common Shares issuable upon exercise thereof, solely for investment purposes.

MBL currently has no plans or proposals that relate to or would result in any of the actions enumerated in paragraphs (a) through (j) of Item 4 of this Schedule 13D filing.  However, MBL reserves the right to change its plans at any time, as it deems appropriate, in light of its ongoing evaluation of (a) its business and liquidity objectives, (b) the Issuer’s financial condition, business, operations, competitive position, prospects and/or share price, (c) industry, economic and/or securities markets conditions, (d) alternative investment opportunities, and (e) other relevant factors.  Without limiting the generality of the preceding sentence, MBL reserves the right (in each case, subject to any applicable restrictions under law or contract) to at any time or from time to time (i) purchase or otherwise acquire additional securities of the Issuer, or

5

instruments convertible into or exercisable for any such securities (collectively, “Issuer Securities”), in the open market, in privately negotiated transactions or otherwise, (ii) sell, transfer or otherwise dispose of Issuer Securities in public or private transactions, (iii) cause Issuer Securities to be distributed in kind to its investors, (iv) encourage (including, without limitation, through communications with directors, management, and existing or prospective security holders, investors or lenders of the Issuer, existing or potential strategic partners, industry analysts and other investment and financing professionals) the Issuer to consider or explore (A) sales or acquisitions of assets or businesses or other extraordinary corporate transactions, such as a takeover bid or scheme of arrangement (including transactions in which MBL and/or its affiliates may be proposed as acquirors), or (B) other changes to the Issuer’s business or structure.
