KELLOGG, IDAHO. New Jersey Mining Company (Symbol: NJMC - OTC Bulletin Board) is pleased to announce more results from our recently completed five hole diamond drilling program near the New Jersey mine property. DDH03-6 was drilled at the Enterprise prospect and intercepted 2.2 meters (1 meter = 3.28 feet) of lead, zinc and silver mineralization at a very shallow depth. The Enterprise is located 0.6 kilometers northeast of the New Jersey mine open pit.

The drill intercept averaged 2.06% zinc, 1.38% lead and 14.7 grams per tonne silver (0.43 ounces per ton) across 2.2 meters at a depth of only 4.4 meters (14.4 feet) below the surface. The mineralization is adjacent to a dike and occurred as sphalerite, galena and pyrite stringers. A sedimentary-exhalative type deposit, similar to the Sullivan orebody is the exploration target at the Enterprise. The Sullivan orebody which is located near Kimberly, B.C. originally contained 145,120,000 tonnes at 6.5% lead, 5.6% zinc and 67 gpt silver. Both the Enterprise and Sullivan are found in the Prichard formation. In the 1950's the Bunker Hill Company drove an exploration drift 200 meters east of the DDH03-6 collar. From our drilling results and geologic interpretation, it appears that this exploration drift did not intercept the projection of the mineralization. The Enterprise intercept is thought to represent a Precambrian mineralizing event which occurred when the sediments were relatively soft.

Another interesting anomaly that turned up in geochemical analyses was elevated levels of tin, up to 320 ppm. Tin is found in the feeder zones of the Sullivan orebody which fed fluids to a mud volcano on the seafloor. Previous rock sampling in the Bunker Hill Enterprise drift discovered a fragment of Prichard formation rock with sulfide layers that assayed 200 grams per tonne silver. Given the results of drilling program, management is encouraged and is making plans for a followup exploration program.

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 six mineral properties in the Coeur d'Alene Mining District: the New Jersey mine, the Silver Strand mine, the Golden Chest mine, the Lost Eagle project, the CAMP project and the Enterprise project.
