Item 3.

Source and Amount of Funds or Other Consideration

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,

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.
