IMPACT Silver Corp. ("IMPACT") is pleased to announce the discovery of the San Patricio Zone and the Cuchara Mine Extension at the Royal Mines of Zacualpan Silver District in Mexico. These results are part of a 10,000-metre drill program ongoing in 2007.
SAN PATRICIO ZONE
The San Patricio Vein is located 3 km southeast of the main mill and 600m west of the Chivo Silver Shoot in the Royal Mines of Zacualpan Silver District. It is a branch vein off the main Lipton Vein system which is host to the flagship Guadalupe mine. On surface, it is marked by an old adit. Four recently completed drill holes returned the following assays:

CUCHARA EXTENSION
The Cuchara Mine is located 3 km east of the mill. The main shoot has been mined intermittently for hundreds of years and was last in production in 2004. Recent drilling tested the southern extension of the Cuchara Vein system beyond historic mining areas and returned the following values:

George Gorzynski, P.Eng. and Nigel Hulme, P.Geo., Qualified Persons under the meaning of Canadian National Instrument 43-101, are responsible for the technical content of this news release. Drill core was NTW size (5.71cm diameter) and BTW size (4.20 cm diameter). Half core samples were collected with a rock saw and tagged for identification. All samples were securely stored at the IMPACT base camp until shipment. A total of 5% assay standards and blanks were inserted into every sample shipment as a quality control measure. All samples were shipped to the ALS Chemex preparation laboratory in Guadalajara, Mexico, where they were fine crushed (70% passing a 2mm screen), pulverized (85% passing a 75 micron screen) and pulp split separated for assay by a riffle splitter. These pulps were shipped to the ALS Chemex laboratory in North Vancouver, Canada, where a 30-gram split of each was assayed for gold and silver by standard fire assay and a 10-gram split was analysed for an additional 30 elements by ICP spectrometry.
IMPACT Silver Corp. is a silver focused mining and exploration company operating in Mexico with a producing silver operation at Zacualpan, an advanced project with a producing mill at Zacatecas and the 200 km2 advanced Mamatla Silver District.
