VANCOUVER, BRITISH COLUMBIA--(Marketwire - Dec. 4, 2007) - IMPACT Silver Corp. (TSX VENTURE:IPT) ("IMPACT") is pleased to announce the discovery of several new silver prospects in the Mamatla District. The wholly-owned 200 square-kilometer Mamatla District is located southwest of and immediately adjacent to the Royal Mines of Zacualpan. Mamatla is host to both epithermal veins and volcanogenic massive sulphide deposits. Field work has demonstrated that some of the veins exploited within the Royal Mines of Zacualpan project extend onto the eastern portion of the Mamatla District. Most of the prospects described below are within trucking distance from the operating mill at Zacualpan.
Field crews began prospecting and sampling at Mamatla immediately after IMPACT won the project in a government auction earlier this year. Much like at Zacualpan, the majority of the targets have historical workings that stopped due to groundwater. These targets will be advanced towards drilling in 2008.
SAN CARLOS AREA PROSPECTS
The ruins of the large historic San Carlos processing plant are located 13 kilometers southwest of IMPACT's operating Zacualpan processing plant. The San Carlos plant appears to have served as a central facility for processing minerals from local mines. At the site, IMPACT crews found seven piles of mineralized rocks varying from 20 - 500 tonnes in size. Samples from these rock piles assayed between 0.06 - 2.12% copper, 0.1 - 17.55% zinc, 0.1 - 11.45% lead, 46 - 836g/t silver and 0.2 - 8.65g/t gold. With the belief that these piles represent mineral collected from various nearby old mines, IMPACT crews began prospecting the surrounding countryside and discovered numerous old mine workings. Samples from some of the first workings discovered are reported below.
PIRUL PROSPECT
The Pirul Prospect is comprised of old mine shafts and adits located 1 kilometer north of the San Carlos plant. Samples from the workings returned the following values:
