 Drilling Extends Mineralization
 
 

KELLOGG, IDAHO. New Jersey Mining Company (OTCBB:NJMC) recently completed drilling an exploratory core hole at its Scotch Thistle prospect near the New Jersey mine in Kellogg. Drillhole DDH04-3 intercepted 6.6 meters that assayed 2.56 grams of gold per tonne (gpt) including 0.9 meter that assayed 13.35 gpt gold.

The Scotch Thistle prospect is located 1 kilometer southeast of the New Jersey mine in Idaho’s Silver Valley, and is part of a 430 acre land area held by the Company. A single core hole was drilled to followup on a gold zone that was discovered by drilling in 2003. This year’s drilling was successful in extending the gold zone to the west and finding higher grade mineralization. Results from this year’s drilling, especially the higher grade gold vein, are quite encouraging. More drilling is planned for 2005. Should the mineralization be continuous on strike and dip, driving an underground ramp for further exploration and resource definition may be justified.

Assay results from the drillhole, DDH04-3, are tabulated below:

The Scotch Thistle prospect hosts a distinctly different type of mineralization than the New Jersey or Coleman vein. While the age and source of gold mineralization may be the same as the Coleman vein, the presence of economic gold grades at the Scotch Thistle in thick intervals greatly increases the exploration potential of the Company’s land package around the New Jersey mine area-of-interest.

New Jersey Mining Company is involved in exploring for and developing gold, silver and base metal ore resources in the Coeur d'Alene Mining District of northern Idaho. The Company has a portfolio of mineral properties in the Coeur d'Alene Mining District including the New Jersey mine, the Silver Strand mine, the Golden Chest mine, the Lost Eagle project, the CAMP project and the Scotch Thistle project.
