Merrex RC Drilling Update

HALIFAX, NOVA SCOTIA -- (Marketwire September 8, 2011) - Gregory Isenor, P.Geo., President and CEO of Merrex Gold Inc. ("Merrex") (TSX Venture: MXI) is pleased to release further assay results from the 2011 RC drill program at the Siribaya Gold Project in West Mali.

Highlights

• Infill RC drilling confirms continuity in 1A substructure
• RC drilling outlines significant 1,000 metre zone in 1A, diamond drill ready
• 31 metres grading 1.58 g/t* in hole TYC11-095

RC Drilling Results

RC drilling continues to increase confidence in the continuity and extension of the gold mineralization within the 1A substructure. Line RC-L-12 (750 metres south of the Zone 1B NI43-101 resource area and at 250 metre spacing between RC-L-4 and RC-L-3) is well-mineralized within the 1A substructure and further demonstrates the continuity of gold mineralization at Siribaya.

See map attached which details RC drill holes planned and completed for the 2011 drill season.

Commentary

"We are now seeing clear evidence of a strongly mineralized footprint within the 1A substructure of Siribaya. This mineralized zone continues to expand and we are confident that with additional drilling this extension to Zone 1A will add ounces to our gold resource" commented Merrex President and CEO Greg Isenor. "We can clearly see the 1,000 metre footprint, noting that it is open to both the north and the south. RC hole TYC 11-095 was especially exciting as when applying a realistic mining width* the hole returned 31 metres grading 1.58 g/t. Additionally the RC holes are generally drilled to not more than 100 metres depth and we know that the mineralization at Siribaya extends to over 250 metres and remains open. Lastly we are getting early indications of gold mineralization in the northern areas along RC lines 9, 10 and 14."

*NOTE: Merrex's standard reporting protocols (as in the Table of Significant Assays below) dictate that an interval of >1 metre of < 0.5 g/t requires a new interval. However, applying realistic mining standards and including a mineralized interval of < 0.5 g/t between two intersections can provide, on occasion, a broader understanding of the mineralization within a drill hole. Hole TYC11-095, for example, has a four metre mineralized interval from 62 - 66 metres depth grading 0.31 g/t between two significant intersections. Calculated as one continuous mineralized down-hole interval, the intersection from 43 metres to 74 metres yields 31 metres grading 1.58 g/t. See details for hole TYC11-095 below:

Table of Significant Assays

(see www.merrexgold.com for full assay list)

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.
Note 2: Intersections in bold characters refer to intersections with a grade > 0.50 g/t Au, and a length > 1.0 m; these intersections appear on the joint map.
Note 3: Intersections are down-hole intervals; true widths are not known at this time.

RC Drilling Program

The Siribaya Gold Project is a Merrex-IAMGOLD Corporation joint project with IAMGOLD Corporation earning-in for 50% of the project. Vesting of IAMGOLD Corporation's interest is anticipated for Q4 2011 or Q1 2012.

The exploration plan for the 2011 RC drill program is for 30,000 metres of drilling across the 1A and 1B substructures to: i) investigate the strike length of the 1A and 1B Siribaya substructures north and south of Zone 1B, and ii) selective infill drilling along 200 -- 300 metre spaced fences to follow up on mineralization intersected during 2010 drilling.

The 2011 RC drill program is designed to test the Siribaya Structure with long 'fences' of heel-to-toe RC holes to identify areas of gold mineralization within. This process of outlining a mineralized footprint has been very successful to date permitting more accurate pinpointing of follow-up detailed diamond drilling.

To date the RC drilling has shown the continuity of mineralization in the Siribaya Structure for 4 kilometres within both the 1A and 1B structures. Previous reconnaissance exploration including soil and termite geochemical sampling, RAB drilling, reconnaissance diamond drilling, high resolution airborne geophysical surveys, and mapping has outlined the Siribaya Structure for 10 kilometres.

There are approximately 16,000 RC samples for which assays are still pending.

To July 18, 2011, a total of 21,506 metres of RC drilling has been completed of a 30,000 metre program planned for 2011.

(A summary of significant assays are listed above; complete assays tables are posted on the Company's website.)

RC drilling is by BLY Mali SA, the Malian division of Boart Longyear Canada of North Bay, Ontario. The project operator is IAMGOLD Corporation.
