Diamond drill results released are for drilling completed up to March 27, 2012, at which time drilling operations were shut down due to political unrest. The holes are located within the Siribaya 1A structure. Assays for all diamond drill holes drilled up to March 27, 2012 have been received and were incorporated in the updated NI43-101 compliant resource estimate released July 30, 2012 which increased the resource to 303,900 oz Indicated grading 2.34 g/t plus 301,000 oz Inferred grading 2.17 g/t.

Diamond drilling resumed in the southern region of the 1A structure on June 25, 2012 and continued until July 14^th when weather forced a temporary suspension until the end of the seasonal rains in the latter part of October. Six holes, totaling 1,322 metres, were completed during June 25^th and July 14^th. Assays are pending for these six holes drilled south of the 1A structure.

Note 1: this table includes exhaustively all the mineralized intersections with a grade > 0.50 g/t Au; these intersections are considered as significant intersections.

RC Drill Results – Siribaya Structure

RC drill results are for drilling up to March 27, 2012. The holes are located within the southern region of the Siribaya 1A structure. All RC drill assays in this release were incorporated in the updated NI43-101 compliant resource estimate released July 30, 2012. There are no RC assays pending for holes drilled in the Siribaya Structure.

RC drilling results will assist target identification for future diamond drilling campaigns.

RC Drill Results – Bambadinka Trend

RC drill results are for drilling up to March 27, 2012. The holes are located within the Bambadinka trend.

The RC assays are consistent with prior soil and termite mound geochemical survey results, and the results of the 10,000 metre (approximately) auger drill program which identified Bambadinka as a gold-mineralized trend. A total of 141 holes (16,946 metres) were completed in the Bambadinka trend and 8,753 assays (7,448 metres) are pending. RC drilling results will assist planning of future exploration programs.

About the Siribaya Gold Project

The Siribaya Gold Project is a joint Merrex-IAMGOLD exploration project in West Mali comprised of approximately 850 square kilometres of gold-prolific exploration permits and permits applications pending where exploration expenditures to date exceed $28 million. IAMGOLD has advised that the required $10.5 million of exploration expenditures under the terms of the Earn In Option Agreement has been completed and that subject to a final accounting review which is nearing completion IAMGOLD will formally vest with a 50% interest in the land package. Exploration of the Siribaya Gold Project is ongoing under a joint management committee. A total of 75,000 metres of drilling (Reverse Circulation, Diamond and Auger) is planned for 2012 at a budgeted expenditure of $11.86 million before contractual overhead fees. However, given the drilling interruption it is anticipated that the total planned program meterage will not be reached during calendar year 2012.
