IMPACT Silver Announces New Silver Discoveries at the Royal Mines of Zacualpan

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 25, 2007) - IMPACT Silver Corp. ("IMPACT") (TSX VENTURE:IPT) 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:

Little is presently known about this nascent discovery. It is open for expansion to the southeast, northwest and down dip. A second phase drill program is being planned for this new zone in the near future. This zone is of particular interest due to its proximity to the Chivo Silver Shoot which is being prepared for near term production (see IMPACT news release dated September 20, 2007).

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:

Mapping and prospecting has identified a cluster of at least ten other veins with old workings in this area. Data compilation and surface work is continuing in preparation for further drilling of the Cuchara Vein extension and other nearby veins.

Drill core was NTW size (5.71 cm 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.
