VANCOUVER, Sept. 4, 2012 /CNW/ – First Mexican Gold Corp. (the `Company` or `FMG`) (TSX-V: FMG, Frankfurt: 21M) would like to announce that additional drilling has been completed at its Guadalupe property in Sonora State Mexico.

The company completed 5 short holes into and around the Karen zone in an effort to better characterize the area of the mineralized zone. The mineralization in the Karen zone has historically been drill indicated to be a high grade area that starts at surface and with strong intensity at shallow depths.

The rationalization for this 281 meter drill program was to test the outer reaches of the known mineralized area in an effort to establish a direction to the source of this occurrence prior to extracting material for possible heap leaching. Following of the mineralized zone to the source may best be successful by way of tunneling through the mineralized zone and following it to the source. All options are being considered at this time for further work on the Karen zone.

Sampling of the core was conducted by halving the core and keeping half of the core in a plastic sack for future lab leach testing. The other half was then cut in half once again and one quarter of the core sent for assay leaving the remaining core in secure storage. The company is aware this may add some variability to the final assays due to the smaller sample mass being sent to the laboratory however the full half core was required to be certain to reach the minimum requirements for possible heap leach testing in the future, as outlined to the company.

Karen zone drill highlights to date: all near surface intercepts, see news releases April 28, 2011 & February 27, 2012.

“The company is considering numerous possible options for future exploration/development at the high grade Karen zone” said Jim Voisin, President and Chief Executive Officer of First Mexican. Mr. Voisin adds: “in these difficult market times for junior exploration companies all options must be on the table to help increase shareholder value and we remain committed to our shareholders to build a good resource base in what we believe to be the high potential Guadalupe property package.” In addition, “I would be remiss if I didn’t draw shareholder attention to the potential amount of money that a major mining company is preparing to invest in our neighbour Corex Gold’s property; this provides some indication of the value of properties in this area.”

Our Diana zone still remains drill ready for an exposed distance of some 700 meters, and funding is being sought to execute the delineation drilling of this zone.

First Mexican Gold advises that it has issued 1,975,000 options to directors and staff at an exercise price of $0.13 with a five year term.
