KELLOGG, IDAHO. New Jersey Mining Company (OTCBB NJMC) announces that it has staked a claim on a high grade silver occurrence in the northern part of the greater Coeur d’Alene Mining District. The discovery is a "greenfields" discovery in that no prospecting work has ever been done at the site. Two large samples of a boulder train in a talus slide near the top of a ridge assayed an impressive 613 and 419 grams/tonne silver (17.90 and 12.24 ounces/ton), respectively. The samples also contained 0.4 grams/tonne gold.

The new property has been named the Silver Button. The silver mineralization consists of black sooty coatings of argentite, a silver sulfide on quartz veining. The host rock is Prichard formation and an igneous intrusion is located nearby. An exploration plan will be formulated which will include geophysics and a helicopter drilling program.

"The discovery of the Silver Button property shows that our exploration strategy is successful. Outlying areas from the well-known, deep silver mines in the Coeur d’Alene Mining District have not been well explored, and the geology is favorable to finding deposits of gold and silver near the surface", said Company President Fred Brackebusch. Management believes that is more economical to conduct surface exploration than to explore for silver at the bottom of a mile deep mine. Mining operations resulting from a successful discovery will also be more economical on shallow deposits.

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, the Scotch Thistle project, and the new Silver Button project.
