Point Location Description: Old shaft and underground workings
Location Method: Conversion from MDI
Access Description: Light aircraft may be able to land on Sturgeon Lake near the trail to the deposit under favourable conditions but these conditions could be rare. Access by boat or snowmobile from Hwy. 599 is possible by access points from Cobb Bay to Horizontal Bay of Sturgeon Lake. The best access from North-east Arm is by boat to the east shore of Morgan Island and to turn west at the northern tip of the island into a narrow north-northeast trending passage which leads to the small terminal bay. The workings are approximately 400 m north of the north shore of the bay. A bulldozer trail leads the way to the workings.
1904: The earliest mention of the property is in an article of the Daily Times Journal, (The Daily Times Journal, Feb. 19, 1904, p.1). Mr. Fawatt, representing the Northern Light Gold Company, was arranging for supplies to be shipped to the site. 1909: An article refers to the property as the Bell Prospect (The Daily Times Journal, September 10, 1909).1911: Moore (1911) visited the property and described the site: What is known as the Northern Light Mine is situated on location H.W. 694, near the northern end of Northeast Bay. There are a number of old camps at the lake shore and the shaft is a little over a quarter mile to the north. This shaft, which is timbered, was nearly full of water and its depth could not be ascertained. The vein is not exposed on the surface, so nothing could be learned beyond the fact that the quartz from the shaft varies from dark to almost pure white, and is mineralized to a small extent with pyrite and chalcopyrite. About 50 paces to the west a pit 12 feet deep exposes a vein 6 feet wide. The veins here are in schist and diorite. This property has not been worked for some years. Last year it was restaked. 1926: Mr. J. Rogers, the claim holder, visited the site to examine the work done by a gang of men, including mining engineers and geologists. (The Daily Times Journal, September 17,1926,p.3). 1980-92: The property was visited on several occasions by the Sioux Lookout Resident Geologist and staff.
Dec 07, 2005 (R Tuomi) - The following description of the Northern Lights prospect is taken from Janes et al. (1990). The Resident Geologist has visited the property several times in the last 10 years. The latest visit was in July 1990. Trowell (1983) mapped the geology at the site as mafic pillowed flows facing and dipping west. The north-trending flows host several conformable gabbro dikes or sills. A number of lineaments in the area trend 070 degrees. Very little outcrop is exposed near the occurrence. One outcrop 200 m south of the trenches exposed mafic metabasalts with a 40 cm wide barren quartz vein striking 020 degrees and dipping 80 degrees south. At the site a series of trenches with 2 crosscuts trend 070 degrees . Trench NL-1 is a 20-foot long crosscut trench trending 140 degrees. It exposes slumped debris of a mafic-hosted breccia with a few angular quartz fragments containing 2 to 3% pyrite. A fire assayed sample returned a trace of gold. Trench NL-2 is an open cut along the dip of a vein trending 250 degrees and dipping 50 degrees south. The vein is 10 cm wide and contains 1 to 3 percent chalcopyrite. To the west end of the trench, the vein splits and 1 portion (or another vein) rolls to the horizontal with a slight rake to the southeast. The horizontal vein thickens to 25 cm at the end of the trench. The vein with the 50 degrees dip is sightly sheared and returned an assay of 0.3 ounce per ton gold. The flat vein returned trace gold. Trench NL-3 is a long open cut along the dip of the 50 degrees dipping vein. The vein varies from 6 to 10 cm and is very sparsely mineralized with pyrite. No samples were taken. Trench NL-4 is an 8-foot square timbered shaft filled with water to 6 m from the surface. Trench NL-5 is a open cut on a flat to slightly dipping white quartz vein. The vein is 20 cm thick and contains a few chlorite slips and less tha 1 percent sulphides. Trench NL-6 was slumped and exposed no outcrop at the time of the visit.

Dec 07, 2005 (R Tuomi) - A grab sample was collected from Trench NL-2 in 1990. The 10 cm wide vein contained 1 to 3 percent chalcopyrite. A sample of the vein assayed 0.30 ounce gold per ton. A grab sample from the shaft muck pile collected by the Resident Geologist in 1992 gave 5.37 ounce gold per ton and trace silver. (DAJ92-0009).
