Other Prospects

No work was performed at the Giant Ledge and Silver Button prospects in the past year and the Company has no exploration plans for either of them at this time. Both prospects are available for option or joint-venture with a qualified party.

Giant Ledge
The Giant Ledge prospect consists of 10 unpatented lode claims covering an area of 200 acres approximately four miles southeast of Murray, Idaho. The property hosts poly-metallic mineralization including lead, copper, and gold in and along the contact of an intrusive stock.

In the 1920s, a 400-foot (122-meter) shaft was sunk and about 1,476 feet (450 meters) of drift development was completed. A flotation mill was erected and minor production was achieved. In the 1950s, Bunker Hill Mining Company examined and mapped the mine workings.

In the 1980s, Sunshine Mining Company completed two core drill holes at Giant Ledge. NJMC was able to procure the drill core from the Sunshine program, then had it re-logged and assayed. Best intercept showed 15.1 feet of 0.027 ounces per ton (opt) gold (4.6 meters of 0.908 grams per tonne (gpt) gold) and 0.24-percent combined copper and lead.

NJMC subsequently completed an extensive soil sampling program in conjunction with a VLF and magnetometer geophysical survey. Sampling results revealed a gold anomaly about 1970 feet (600 meters) in diameter, coincident with a magnetic low from the magnetometer survey.

Silver Button
The Silver Button property is a high grade silver occurrence that was discovered and staked by the Company in 2004. It covers 20 acres of northern Idaho’s Clark Fork mining district, 60 miles north of Kellogg and 10 miles west of the Troy Mine which has produced 44 million ounces of silver and 390 million pounds of copper.

There is no evidence that modern prospecting work has ever been performed at Silver Button, prior to preliminary field sampling by the Company. Two large samples of a boulder train in a talus slide near the top of a ridge assayed 17.90 and 12.24 opt silver (613 and 419 gpt silver). The samples also contained 0.4 gpt gold. Silver mineralization at Silver Button consists of black sooty coatings of acanthite, a silver sulfide on quartz veining. The host rock is Prichard formation and an intrusive is located nearby.
