Mr. Coetzer has over 24 years of international mining experience, having held increasing levels of responsibility in various mining companies including Kinross Gold Corporation, Xstrata Nickel, Xstrata Coal South Africa, and Placer Dome, with particular emphasis on integration and streamlining of operations. From February 2010 until joining the Corporation, he was the Senior Vice-President, Red Back Integration, and from May 2009 to February 2010 he was Senior Vice-President, South American Operations, for Kinross Gold Corporation.

From June 2007 to October 2008, Mr. Coetzer was the Chief Operating Officer of Xstrata Nickel and from March 2006 to June 2007 he was Chief Operating Officer of Xstrata Coal South Africa. Mr. Coetzer also has significant experience in Africa, having been with Placer Dome Inc.’s South African and Tanzanian operations since 1996, most recently as the Managing Director - South Africa and the Executive General Manager - Tanzania from 2003 to 2005.

The Company entered into an employment agreement (the “Agreement”) with Mr. Coetzer as of March 9, 2011. The Agreement provides for employment for one-year terms with automatic renewal for successive one-year periods and an annual base salary of US$450,000, as may be increased from time to time during the term of the Agreement. Mr. Coetzer is entitled to participate in the Company’s Third Amended and Restated 1997 Stock Option Plan (the “Option Plan”), the Executive Management Performance Bonus Plan, and benefit and deferred compensation plans generally available to executive officers of the Company from time to time.

Pursuant to the Agreement, Mr. Coetzer shall receive a starting bonus of US$100,000. On March 9, 2011, Mr. Coetzer was granted 400,000 options under the Option Plan, of which 25% are vested and the remaining 75% will vest in three equal installments of 25% on the day prior to the anniversary dates of the grant during the next three years of employment. The options are exercisable at Cdn$2.83 per share (US$2.91), which was the closing price of the Company’s common shares on the Toronto Stock Exchange on March 8, 2011, the day immediately preceding the grant date as provided by the terms of the Option Plan.

Subject to the terms of the Option Plan, all of the stock options granted to Mr. Coetzer under the Option Plan shall become vested and immediately exercisable for a period of 12 months from Mr. Coetzer’s date of termination (a) upon a change in control, or (b) if after March 9, 2012, (i) the Company’s failure to elect Mr. Coetzer as a vice president of the Company or to an executive position possessing comparable responsibilities, or (ii) termination without cause.
