BARRICK CONFIRMATION ACKNOWLEDGEMENT

TO:	XXXXXXX GOLD CORPORATION (“Barrick”)
AND TO:	SPROTT RESOURCE LENDING PARTNERSHIP, in its capacity as agent under the Credit Agreement (as defined below) (“Sprott”)
AND TO:	THE LENDERS (as defined below)

Reference is made to an Option to Purchase (Back-In Right Agreement) between Barrick and Lake Shore Gold Corp. (“Lake Shore”) dated August 18, 2011 (the “Back-in Agreement”).

Pursuant to a credit agreement dated as of June 13, 2012, as amended, between Lake Shore, as borrower, and Sprott, as agent, and the several lenders from time to time parties thereto (such lenders being the “Lenders”, and the foregoing credit agreement, as amended, supplemented, revised, restated or replaced from time to time being the “Credit Agreement”), Lake Shore entered into certain credit facilities with Sprott and, as security for the performance of Lake Shore’s obligations to Sprott and the Lenders pursuant to or in connection with the Credit Agreement, has granted to Sprott (for its own benefit as agent and for the benefit of the Lenders) security (the “Sprott Security”) over Lake Shore’s interest in the Back-in Properties (as defined in the Back-in Agreement).

Pursuant to the Back-In Agreement, Lake Shore has requested that Sprott confirms certain matters to Barrick, all as more particularly set out below.

1. Sprott in its own right and as agent for the Lenders hereby:

(a) confirms that Xxxxxxx’x Back-in Right shall not be postponed or subordinated in any manner whatsoever to any security interest granted by Lake Shore to Sprott and the Lenders in the Back-In Properties pursuant to the Sprott Security;

(b) confirms that Lake Shore will be permitted (or, in circumstances provided in the Back-in Agreement, Barrick shall be permitted) to obtain a discharge of the Sprott Security registered against the Back-In Properties upon payment to Sprott on account of the outstanding balance under the Credit Agreement of an amount equal to the Consideration (as defined in the Back-in Agreement) payable by Barrick to Lake Shore under Section 4(d) of the Back-in Agreement upon the exercise by Barrick of the Back-In Right (which discharge, for greater certainty, shall not include a discharge of any security interest granted by Lake Shore in favour of Sprott over Lake Shore’s interest in the joint venture formed pursuant to the Back-in Agreement or any other properties or assets of Lake Shore); and

(c) acknowledges Xxxxxxx’x rights under the Back-in Agreement and the asset purchase agreement dated May 4, 2011 among Xxxxxxx Gold Corporation, Xxxxxxx Gold Inc., LAC Properties Inc. and Lake Shore, as it relates to the Back-In Right, and agrees that it will hold and deal with the Sprott Security so as not to frustrate or impair such rights of Barrick.
