Genco Reports Results for the Period ended September 30, 2007

November 28, 2007 – Vancouver, B.C., Canada – Genco Resources Ltd. [TSX Venture Exchange: GGC] announces the results for its third financial quarter ended September 30, 2007 and provides an update on mining activities during the same period. For the nine month period, Genco had revenues from metal sales of $5,475,664, an operating profit of $2,518,073, and a net loss of $2,512,375. Net assets increased during the period $23,798,698 to $46,243,773.

Reduced revenues and metal production were primarily the result of a test mining program undertaken at La Guitarra Mine during the first four months of 2007. This test mining program was undertaken to gain factual data regarding metal recoverability and mining costs for the Creston Deposit. This information will be used in the mine expansion feasibility study currently being conducted by Kappes, Cassiday and Associates and by the Genco to develop a long term strategy for the Temascaltepec Mining District.

Approximately 16,000 tonnes of ore grade material were taken from surface and processed in La Guitarra’s flotation mill. By processing ore obtained from the Creston test mining and surface program the Genco was able to determine silver and gold recoveries using its conventional flotation circuit and also obtain samples of surface oxide ores for further bottle roll and column tests. Over the test period recoveries improved from the low 70% range for silver and low 60% range for gold to over 80% recovery for both silver and gold. Bottle roll and column tests are ongoing to determine the metal recoveries using cyanide mill processing and heap leach processing.
