Dec 07, 2005 (D McKay) - Bow (1898) describes this property: On August 11, I went to Middleton with Mr. Duncan McIntyre of Jackfish to examine locations 590, 591 and 592X, owned by J.E. Newsome of Port Arthur. These locations are two and a half miles north of the railway track, and the same distance west of Middleton. We visited the properties and examined some of the veins, but I had a chance of examining it more thoroughly on the 20th of the month, when I was able to see all the veins in company with the original discoverer. The formation is trap and green schist, with a strike of east and west. These are four or five veins besides some felsite dikes and fahlbands. All the veins except one, No. 4, run east and west, while No. 4 is apparently a fissure, as it runs north and south. A little blasting and test pitting has been done on this veins, as well as one or two others on the property. At the north end of the property is a large fahlband which crosses the locations. It measures 70 or 80 feet in one place. Parts of it were very much oxidized. No. 4 is apparently a fissure vein. It runs north and south on 592X, and outcrops in two places a few hundred yards apart. It shows a good width where exposed.

Dec 07, 2005 (D McKay) - No. 1 vein, which is farthest south, outcrops in one place as a small mountain of ore about 400 feet long, over 100 feet wide, and rises one to two hundred feet above the ravines around. The material appears to be all quartz on the surface and felsite on the west bluff, which is the boundary at that end. It is heavily charged with pyrite in places. Mr. Finlay D. Grant, the prospector, informed me that it could be traced for miles, but the only other outcropping, which was doubtless a continuation of the same, occurred about two or three hundred feet to the east of the large body. It was 25 or 30 feet wide as far as could be determined from what little stripping was done. No. 2 is a vein seven or eight feet wide of nearly solid quartz, which is not exposed very far, but, it is said, can be traced for a good distance. No. 3 appears to be be one of the best veins. It is traceable for over half a mile and shows a good width. In one place it measures 14 feet of solid quartz and at other places from three to four to eight or 10 feet. But like all the veins, it is covered with moss and vegetation and is only seen where this has been stripped off. These bodies are nearly all unusually large, but it is probable that they will prove in most cases to be low grade, and that only large stamp mills can treat them successfully. I saw several other large veins in this part of the country, but it is likely that they are all the same in this respect.
