Canadian Zinc Reports Exploration Results.TORONTO -- Canadian Zinc Corporation today reports results from the first phase of its summer 2004 exploration programme at its Prairie prairie Level or rolling grassland, especially that found in central North America. Decreasing amounts of rainfall, from 40 in. (100 cm) at the forested eastern edge to less than 12 in. Creek property in the Northwest Territories Northwest Territories, territory (2001 pop. 37,360), 532,643 sq mi (1,379,028 sq km), NW Canada. The Northwest Territories lie W of Nunavut, N of lat. 60°N, and E of Yukon. . Diamond Drilling Diamond Drilling is a highly specialized industry used for mineral exploration around the world. Most commonly using wireline and core bits with diamond encrusted matrix. To drill holes to max depths of twelve thousand feet, for the recovery of core used in verifying mineral The surface diamond drilling programme began in June 2004 utilizing two of the Company's Longyear diamond drill rigs operated by Advanced Diamond Drilling Ltd. of Surrey, B.C.. It is expected that a total of 27 holes will have been drilled during the season which will total about 6,000 metres of core. Assay results for the first 15 holes, drilled to the end of July, have now been received from Acme Laboratories Acme Laboratories is the home page for a number of open source software products written and maintained by Jef Poskanzer. Major projects maintained at ACME include pbmplus and thttpd. , Vancouver. There have been extensive delays in receipt of assays from the laboratory due to the substantial volume of exploration activity. The summer exploration programme had three different objectives or targets: infill in·fill n. 1. The use of vacant land and property within a built-up area for further construction or development, especially as part of a neighborhood preservation or limited growth program. 2. drilling; mine site exploration drilling; and northern down dip extensions.

"The excellent results from the infill drilling confirm our geological interpretation of the deposit and increase our confidence in the resource in the area from which it is expected early initial production will take place" said Alan Taylor
Mine Site Area This phase of the drilling programme explored the limits of the vein system to the south towards the mill site and outside the predefined area of the mineral resource. A series of eight relatively shallow holes all intersected the host structure with low grades of metal whilst one hole (#143) intersected a high grade vein with a combined zinc/lead grade of 51.4% with 12 ounces of silver per tonne, over a width of 0.7 metres, at a relatively shallow depth of 105 metres. Hole 147, which was drilled off strike to the east outside the known resource, intersected a combined zinc/lead grade of 38.1% with 8 ounces of silver per tonne, over a width of 1.1 metres, at a shallow depth of 82 metres.

"The intersection of high grade zinc/lead in two separate holes (#143 and #147) in this area outside the known resource is particularly noteworthy for future exploration", said Mr. Taylor. In the same general mine site area, three holes were drilled targeted at stratabound potential. Two of these holes (#137 & #139) intersected massive to semi-massive pyrite pyrite (pī`rīt) or iron pyrites (pīrī`tēz, pə–, pī`rīts), pale brass-yellow mineral, the bisulfide of iron, FeS2. zones with minor amounts of zinc and lead (hole #137-6.6% zinc and 2.1% lead; hole #139-5.1% zinc and 6.6% lead) at shallow depths about 40 to 50 metres from surface in a geological setting similar to that of the previously discovered stratabound mineralization.

Northern Downdip Extension Three deep holes have been drilled in this area targeted at vein mineralization outside the area of underground delineation set out in the 2001 Scoping Study. Assay results are not yet available for these holes. The drilling programme will continue until early October at which time the surface exploration programme will be completed at Prairie Creek for the season.
