Impact Silver Announces New Discovery at the Royal Mines of Zacualpan

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 18, 2007) - IMPACT Silver Corp. ("IMPACT") (TSX VENTURE:IPT) is pleased to announce a new discovery on the San Antonio Target within the Royal Mines of Zacualpan Silver District. Recent drilling returned the highest zinc and lead grades with significant gold and silver mineralization encountered by IMPACT to date. These results are part of the 10,000m drill program budgeted for 2007.

The San Antonio zone is located 4km southeast of the Zacualpan mill. On surface, it is marked by a glory hole measuring 45m x 3m x 30m deep, two adits and a foundation for an old processing plant. The mineralized intercepts occur below the water table, which appear to have been left undisturbed by historic mining. Highlights of the recent eleven-hole drill program include:

Drill holes Z07-16 to Z07-19 were drilled to test the southeast boundary of the system and intersected lower grades. The zone remains open for expansion to the northwest. Surface work is continuing in preparation for phase two drilling.

Vice President of Exploration, George Gorzynski, said: "We are very excited about San Antonio. After San Ramon and Chivo, this is the third discovery with near-term production potential made by our team in Zacualpan since the acquisition of the project."

Drill core was NTW size (5.71cm diameter) and BTW size (4.20cm diameter). Half core samples were collected with a rock saw and tagged for identification. Chip and channel samples were collected from cleaned rock faces in old mine workings and from bedrock outcrops over a continuous representative interval using a moil and hammer. 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 analyzed 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 200km2 Mamatla Silver District.
