First Mexican Updates Exploration Program in Sonora, Mexico

VANCOUVER, BRITISH COLUMBIA--(Marketwire - March 10, 2011) - First Mexican Gold Corp. (TSX VENTURE:FMG) is pleased to report results from hole HDH 11-11 and completion of a first phase 3D IP (Induced Polarization) survey from the Diana zone on the Guadalupe property package which is contiguous to Corex Gold Corp (TSX VENTURE:CGE) Santana Property where consistently good exploration results have been demonstrated.

This drill hole is the last to report from the 8 hole drilling program completed in February 2011, where 5 holes were completed on the Karen zone which had been identified and now confirmed as a high grade target, and 3 holes on the Diana zone which was identified as a lower grade, potentially large tonnage target.

Highlighted intercepts to date on Dianna zone:

  • HDH 11-09, 11.3 metres of .91 g/t Au, 142 g/t Ag
  • HDH 11-10, 29.1 metres of .47 g/t Au, 172 g/t Ag
  • HDH 11-11, 13.3 metres of .75 g/t Au, 195 g/t Ag

Hole HDH 11-10 and HDH 11-11 were drilled on the Diana zone based on previous trenching and surface expression visible on a ridge that contains interesting alteration and sample results. Likewise hole HDH 11-09 was drilled on the same ridge on the Diana zone some 400 metres to the east and along strike of the altered rock mountain ridge.

The results of previously released holes HDH 11-10 and HDH 11-09 along with new results of hole HDH 11-11 are tabled below. These holes exhibit mineralization from surface in sufficient potential value and continuity to be of interest to the Company for immediate further drilling.

Induced Polarization (IP) responses to date on the Diana zone have now indicated that there is a corridor of chargeability between these two drill holes that also extends West on trend an additional 400 metres past hole HDH 11-10 for a total chargeability anomaly of 800 metres. Based on these results and strong clearly defined IP response, First Mexican has decided to mobilize a drill to the site and begin a tight spaced drill program on the Diana zone. P&E Engineering of Toronto will be responsible for QA-QC practices on this drill program which will begin prior to month end.

Additional areas of chargeability from the IP survey have been detected in the vicinity of the Linda zone with chargeability extending some 700 metres towards the Luce zone. Based on final IP survey data for all areas being surveyed, a second drill will be contracted and mobilized. 3D IP is presently being conducted and completed over the high grade Karen zone with final results pending. The IP survey is also presently moving towards the Bailey zone which is a high priority target and this area should complete the current planned IP survey.

"We are pleased to have confirmed our expectations of the lower grade/higher tonnage potential at the Diana zone with this initial round of drilling. The IP survey, soil/rock chip sampling and drilling show a high degree of correlation and continuity in the Dianna zone giving us confidence to move forward with more aggressive drilling in this zone," said Jim Voisin, President and Chief Executive Officer of First Mexican. Mr. Voisin adds: "The ongoing IP survey data will greatly assist in further delineating more aggressive drilling plans for the Karen and Bailey zones plus potentially the Linda/Luce zones."

SJ Geophysics Ltd. of Delta, B.C. has just completed an extensive IP survey (Induced Polarization) now totaling 40 kilometres of lines. This 3D IP program is designed to enhance the drill targeting over future multiple target rich areas and provide follow-up data to assist in the next phase of drilling within our continually expanding property package.
