KELLOGG, IDAHO. New Jersey Mining Company (Symbol: NJMC - OTC Bulletin Board) has completed preliminary metallurgical testwork on ore from its Silver Strand mine. The purpose of the testwork was to determine a feasible process for recovering silver and gold from the Silver Strand ore as part of an engineering exercise for a possible seasonal mining operation.

This phase of testwork consisted of flotation and cyanidation tests. A bulk sulfide flotation concentrate was produced by the testwork. Assays of the concentrate ranged from 16 to 47 grams/tonne gold and from 4,200 to 13,500 grams/tonne silver. The tailings from the flotation tests were leached with cyanide, increasing total recoveries of gold and silver to the 90% level. Testwork is planned to treat the concentrate using pressure oxidation to make the concentrate amenable to cyanidation as an alternative to sale of concentrate to a smelter.

In other news, the Company has completed building the road for access to the drill site for the planned diamond drilling program at the New Jersey mine this year. The drill target is the northernmost geophysical anomaly which was found by the induced polarization (IP) and resistivity survey last autumn. The target is about 240 meters north on strike from the known orebody. The new road should provide access to possible future drill sites as well. About one kilometer of road was constructed. Efforts will now focus on selecting a contractor to drill two holes each with a planned depth of 150 meters.

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 four mineral properties in the Coeur d'Alene Mining District: the New Jersey mine, the Silver Strand mine, the CAMP project and the Wisconsin-Teddy project.
