VANCOUVER, BRITISH COLUMBIA--(Marketwire - Oct. 4, 2007) - IMPACT Silver Corp. ("IMPACT") (TSX VENTURE:IPT - News) is pleased to announce results from an initial sampling program undertaken on the wholly-owned Nueva Granada and Asturiana concessions in the Zacatecas Silver District.

The concessions cover both the San Jose Vein and the Armado Vein, which are branches of the Veta Grande vein system. Historically, the Zacatecas Silver District has produced over one billion ounces of silver, of which the Veta Grande vein system was the largest contributor. Historical mine plans indicate that these two veins on IMPACT's concessions were mined along a length of 800m and to a depth of 150-200m.

SAN JOSE VEIN

The San Jose Vein crosses the concessions over a distance of 800m. Old mine workings and dumps mark the surface along its entire width. A total of six channel samples were collected from surface exposures of the vein and averaged 239g/t silver over 0.74m true width ("TW"), ranging to a high of 444g/t silver over 1.10m TW. Five old mine dumps were also sampled along the vein. Two samples were collected at each dump site. The average of the five sulphide-bearing samples was 407g/t silver, ranging to a high of 1,070g/t silver. The average of five sulphide-poor samples was 141g/t silver, ranging to a high of 390g/t silver.

ARMADO VEIN

The Armado Vein trends 100m west of and runs parallel to the San Jose Vein. It has been traced over a distance of 500m and is marked by old mine workings and dumps along its entire length. Channel samples collected from surface exposures of the vein located 130m apart assayed 237g/t silver over 1.92TW and 1,320g/t silver over 0.30mTW. Two samples were collected at an old mine dump on the vein located 400m to the north. A sulphide-bearing sample assayed 358g/t silver and a sulphide-poor sample assayed 247g/t silver.

Several splay veins branch off the main Armado Vein. A channel sample from a splay vein in the southern portion of the concessions assayed 188g/t silver over 1.04m TW. At this location, a sulphide-bearing sample from the old mine dump assayed 556g/t silver and a sulphide-poor sample assayed 54g/t silver.

IMPACT has an option to purchase a 200-tonne-per-day processing plant that is located in the center of the Zacatecas Silver District and six kilometers south of the concessions. Presently, the plant is being operated on a custom milling basis for local miners.

Based upon the encouraging results from this initial field work and the concessions' close proximity to the processing plant, a first phase drill program is being planned.

Edward Lyons, P.Geo., a Qualified Person under the meaning of Canadian National Instrument 43-101, is responsible for the technical content of this news release. Chip and channel samples were collected from cleaned rock faces over a continuous representative interval using a chisel and hammer. 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 with a producing silver operation at Zacualpan, Mexico, an advanced project with a producing mill at Zacatecas, Mexico, and other projects in the Dominican Republic. Energold Drilling Corp. (TSX VENTURE:EGD - News) owns 6.6 million shares of IMPACT.
