Kellogg, Idaho. New Jersey Mining Company (OTCBB:NJMC) is keen to announce that its diamond drilling contractor has mobilized to the Golden Chest mine in Murray, Idaho this week to commence a drilling program to further define a gold zone discovered last year with a high-grade drill intercept on the Idaho vein. A four hole program with 610 meters of drilling is planned at the Golden Chest, where the Company holds a 500 acre land position.

Idaho Vein Target

Last year, NJMC completed a four hole drilling program of which the highlight was DDH04-6 which was drilled through the Idaho vein deeper than any previous drilling and intercepted a 20.8 meter zone containing 4 veins that assayed 4.26 grams of gold per tonne (gpt), including a higher grade section of 5.8 meters that assayed 10.68 gpt gold. A one meter sample length of the high grade section assayed 35.8 gpt and gold was visually identified. A preliminary calculation of the true width of the entire zone was 13.3 meters or about 64% of the drilled intercept. Additionally, a fifth vein was intercepted 5 meters above the zone and assayed 7.27 gpt gold over 0.5 meters.

Previous drilling by Newmont Mining in the late 1980's was targeting gold mineralization amenable to open pit mining so the drillholes were relatively shallow and were not drilled into the Idaho vein below the No. 3 Level where it appears the gold grade is significantly higher. NJMC’s management feels that a substantial gold resource (+1.5 million ounces) suitable for a 1,500 tonne per day underground mine could be defined on the Idaho vein because of it’s large dimensions and the excellent gold grade discovered last year. The Idaho vein system outcrops impressively in large quartz promontories which are 30 meters in width, and 256 meters above the gold zone drilled by DDH04-6. Most of the open pitable resources drilled by Newmont are part of the Idaho vein system or zone, which could be mined in conjunction with underground resources.

Because mining experience at the Golden Chest shows that veins are relatively uniform on dip, the first hole will be drilled about 30 meters down dip from the 2004 intercept. Then two additional holes will be drilled to either expand the strike length or to explore further down dip. If the continuity of the Idaho vein system appears good, a new ramp will be considered to access the deeper gold mineralization.

Current Mining Operations

Ore is being produced from the Katie vein approximately 500 meters north of the Idaho vein described above and in a similar structural setting as the Idaho vein. The mining operation is performing well and according to Management’s expectations with about 400 tonnes per month grading from 11 to 15 grams/tonne gold. The operation is generating about $25,000/month cash which is being used for exploration and corporate expenses. There is potential to expand the mining operation by locating more reserves in parallel veins or in additional shoots. One short drillhole will be drilled to test for a parallel footwall vein, called the Dora vein which has historic production.

The Golden Chest mine is operated under a mining lease with Metaline Contact Mines (OTCBB: MTLI).

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