Metallurgical Testing Demonstrates High Recovery Rates for Gold & Silver on First Mexican, Karen Zone

March 5, 2012

Vancouver, British Columbia, First Mexican Gold Corp. (the `Company` or `FMG`) (TSX-V: FMG, Frankfurt: 21M) is pleased to report results of some recent metallurgical testing conducted on the high grade Karen zone from the Guadalupe property in Sonora State, Mexico.

The metallurgical bottle roll recovery tests have been performed on the high grade material extracted from the Karen Zone where the company now holds a 100% ownership interest having recently completed a transaction with its former JV partner.  This continues the efforts to build not only a resource but develop the data base needed to further enhance development of the project.  This zone may be amenable to low cost extraction methods.

Laboratorio Tecnologico De Metalurgia LTM S.A. de C.V. of Hermosillo, Mexico, conducted the bottle roll test in an effort to determine the recoverability of the material obtained from drilling. The recovery testing provided an 81.34% recovery of gold and 88.61% recovery of silver with copper recovery not tested.

As a follow-up, the company is considering leach pad testing on the Karen zone material once enough material has been gathered. Leach pad testing is also being considered on the brecciated material of the Diana zone that can easily be removed from a road cut in large enough quantities for the test to be meaningful.

The Diana zone is visible on surface at the crest of a mountain ridge that extends in excess of 450 metres, plus exposure on road cuts in the area extend the exposed zone to a minimum of 750 metres in length. A 32 diamond drill hole program comprising 5000 metres of closely spaced holes has been designed to define mineralization resource calculation along 400 metres of the exposed zone. The Diana target is a strongly altered breccia zone that appears to be standing near vertical with widths near surface of 30 to 50 metres.

Please refer to previously reported assay results below.

“The company intends to continually build the data base associated with both the Karen zone and Diana zone so that all options for future development can be considered," said Jim Voisin, President and Chief Executive Officer of First Mexican.  Mr. Voisin adds: "the company has defined zones on Diana with the potential to build a significant resource, whereas many juniors do not have this option at this early a stage in their development and this helps differentiate FMG from others.”

John Archibald, PGeo, a qualified person pursuant to NI 43-101, has reviewed and approved the technical information in this press release on behalf of the company.

First Mexican Gold Corp is an active explorer for precious metals in Mexico and has now completed the acquisition of 100% interest in the Guadalupe property package.  The Company now controls a total of 15,112 hectares in this high potential exploration area.
