Silvermex Resources Acquires El Rayo Claims in Mexico, Underground Channel Sampling by the Company Returns Assays as High as 2.79 Kilos of Silver Across 3 Metres

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Nov. 27, 2007) - Silvermex Resources Ltd. (the "Company") (TSX VENTURE:SMR) has entered into an agreement to acquire a 100% interest in the 150 hectare El Rayo Claims located in the municipalities of Santa Ana and Magdalena de Kino, State of Sonora, Mexico. The Company has staked an additional 2,200 hectares to ensure the mineral rights to any extensions to the known mineralization are secured. To exercise the option the Company must pay a total of US$315,000 over a period of two years. In addition, the Company is required to issue 250,000 common shares for every 10 million ounces silver identified in measured and/or indicated mineral resource categories (CIM definition). The Vendor is an arm's-length party and retains no royalties on the claims. The acquisition is subject to approval by the TSX Venture Exchange.

Silvermex has recently completed a first phase exploration on the claim block. This included prospecting, sampling and reconnaissance mapping along 750 metres of intermittent exposures of a northwest trending, brecciated, shear zone that dips 50 degrees to 75 degrees to the southwest. Widths vary from 0.50 to 15 meters with a 12 meter wide zone exposed in the old underground workings. The mineralization consists of pyrite, galena and sphalerite boxworks, and calcite stockworks hosted in a volcanic breccia. The sulphide mineralization appears to relate to the silica flooding.

A total of 60 samples including 8 channel samples from the underground workings were taken. The assays from the underground sampling returned 665 g/t silver, 0.83% lead, 0.50% copper and 0.43% zinc across an average width of 12 m.

The silver, lead, zinc and copper values have been traced for at least 150 to 200 m along strike of the mineralization zone with the highest silver values returning from the exposures near the portal of the underground workings.

The Company is planning a more intensive surface and underground program for the first quarter of 2008 consisting of detailed geological mapping, sampling and trenching. The objective of the program will be to identify parallel structures and confirm the continuity of the known mineralized systems.
