IMPACT Silver Announces New Discovery at the Royal Mines of Zacualpan

VANCOUVER, BRITISH COLUMBIA--(Marketwire - April 29, 2008) - IMPACT Silver Corp. ("IMPACT") (TSX VENTURE:IPT) is pleased to announce a new discovery, the Los Reyes Zone, within the Royal Mines of Zacualpan Silver District in Mexico. Recent drilling of this new discovery returned wide, mineralized drill intercepts within close proximity to the operating Chivo Silver Mine.

LOS REYES ZONE

Discovered through the ongoing regional surface and underground sampling program at Zacualpan, the Los Reyes Zone is located 4.5 kilometers southeast of the Zacualpan processing plant and 600 meters east of the Chivo Silver Mine. It is a thick vein system that trends parallel to the silver-rich Chivo Vein. On surface, Los Reyes is marked by a series of old mine workings. Highlights from the eleven-hole drill program include the following:

The other holes in this program intersected lower grades. The holes were drilled on a 35 x 50-meter grid over a length of 200 meters. The zone is open for expansion to the northwest, southeast and down dip.

Several splay veins branching off the main Los Reyes Vein returned significant assays from the drill program as follows:

With its close proximity to the operating Chivo Silver Mine, Los Reyes Zone could readily be accessed underground from existing mine workings. IMPACT's mine staff will evaluate the Los Reyes Zone for possible integration into the Chivo Mine plans.

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 5% 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 2 mm 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 analyzed for an additional 30 elements by ICP spectrometry.
