Diamond drill results released are for six holes totaling 1,322 metres drilled between June 25, 2012 and July 14, 2012 when weather forced a temporary suspension until the end of the seasonal rains. All holes were drilled in the Siribaya 1A substructure south of the Zone 1A resource area. Of the six holes drilled, three returned significant assay intersections including hole TY-DD 12-069 which included 2.30 g/t Au over 3.0 m; three holes did not return significant intervals.

Table of Significant Assays for Diamond Drill Program Siribaya 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.

Diamond Drilling Resumes

Diamond drilling has resumed after a temporary suspension due to the seasonal rains. The drill is presently located on the 1A sub structure and drilling south of the 1A resource block in the area of TY-DD-12-068 and 069 to test for potential gold mineralized cross-structures.

A total of 75,000 metres of drilling (Reverse Circulation, Diamond and Auger) was planned for 2012 at a budgeted expenditure of approximately $12 million. However, given the drilling interruption that followed the political unrest in March 2012, the total drill meterage originally planned for 2012 will not be reached during this calendar year. To date, approximately 18,946 metres of RC, 5,024 metres of DD and 1,030 metres of auger drilling are complete. It is anticipated that approximately 3000 metres of additional diamond drilling will be completed by calendar year end.

2013 Exploration Program

The 2013 Siribaya exploration program design and budgeting is in progress. It is expected that by year end the 2013 exploration program will be agreed to and budgets approved.

Commentary

“The drill results from these holes are interesting, especially hole 12-069 which returned a 21 metre mineralized interval between 19 and 39 metres depth,” commented President and CEO Greg Isenor. “However, the interpretation of all of the drill holes is still underway and the possibility of cross faults is being considered. The holes will be incorporated into our global interpretation which in turn will be used for planning both the remaining diamond drilling for 2012 and the overall exploration program for 2013.”

About the Siribaya Gold Project

The Siribaya Gold Project is a 50/50 joint Merrex-IAMGOLD advanced-stage gold exploration project in West Mali comprised of approximately 910.5 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. The accounting review of those expenditures is substantially complete after which IAMGOLD’s 50% interest in the land package will formally vest. Exploration of the Siribaya Gold Project is ongoing under a joint management committee.

Merrex is primarily a West African focused gold exploration company with experienced management, a solid exploration team, a prominent gold-producer as a partner and an expanding gold resource…a winning combination offering investors an extraordinary opportunity.
