Genco Discovers Significant Mineralization through Reconnaissance Drilling

VANCOUVER, BRITISH COLUMBIA--(Marketwire - March 26, 2008) - Genco Resources Ltd. (TSX:GGC) is pleased to announce the initial results of its reconnaissance drilling program in the Temascaltepec Silver/Gold Mining District, Mexico State, Mexico. Highlights include GDH171 which intersected 1.5 metres grading 672 grams per tonne ("g/t") at 315 metres in the Socorro vein system located in the San Simon area in the eastern portion of the District. Drilling on the Jessica vein system in the Coloso area located in the northwest portion of the District returned 1 metre grading 1,030 g/t silver and 2.50 g/t gold in hole GDH180 and 0.8 metres grading 1,020 g/t silver and 1.05 g/t gold.

The following tabulates the results of this initial reconnaissance drilling program.

True-widths of the veins are unknown at this time as these are the first holes drilled on the targets. The equivalent silver ("eAg") grades are based on a 50:1 silver to gold ratio ($550/oz gold and $11/oz silver).

The three holes in the Coloso area are spaced a minimum of 100 metres apart along strike on the Jessica vein system. GDH167 is the only hole to have tested the Magdalena vein system and GDH171 is the first and only hole to have tested the Socorro system.

Four holes drilled in the Real de Arriba area intersected low grade mineralization in multiple structures. All holes failed to penetrate the Las Animas vein system due to deviation of the core hole.

Genco's President Gregory K. Liller stated, "We are extremely pleased that our first reconnaissance drilling program is returning excellent results. To have intersected multiple high grade silver veins in the first holes drilled on these widely spaced targets confirms our belief that the Temascaltepec Silver/Gold Mining District has significant exploration potential outside of the current area of operations, and is one of the largest silver exploration projects currently being explored in Mexico."

"As we are concluding the infill drilling around La Guitarra's mine complex, that is necessary for the feasibility study, we will be able to devote more of our drilling efforts toward exploration of the greater Temascaltepec Mining District. Following the spring drilling break, we will be returning to the San Simon area with one core rig and the Coloso area with two core rigs. Our objective is to rapidly identify and develop additional underground production centers in order to provide long term mill feed for our planned mill expansion."

Quality Control & Assurance

Genco has implemented a quality assurance and control (QA/QC) program to ensure sampling and analysis of all exploration work is conducted in accordance with the best possible practices. The drill core is sawn in half with one half being stored on site and the other half shipped to either the ALS Chemex Laboratories in Guadalajara, Mexico, or the SGS Laboratory in Durango for preparation of pulps. In the case of GDH167 and 171 pulps were shipped to ALS Chemex's Vancouver, B.C. Canada laboratory for analysis using a 3 acid digestion for silver and fire assay with AA finish for gold. In the case of GDH178, 180 and 182 SGS employed gravimetric fire assay techniques for both gold and silver at their Durango laboratory. The laboratory reassays about 3% of all samples as a check and additional checks may be run on anomalous values. In addition the La Guitarra mine laboratory has an ongoing check assay program and routinely reassays ALS Chemex's pulp and sample rejects and/or the retained core splits.
