Page 64 - The following are the general rules : — (1.) An adequate amount of ventilation shall be constantly produced in every mine, to dilute and render harmless noxious gases to such an extent that the working places of the shafts, levels, stables, and workings of such mine, and the travelling roads to and from such working places, shall be in a fit state for working and passing therein.
Page 224 - ... of some of the gold deposits of Porcupine. Irregular and lenticular bodies of quartz often occur which may have a width of ten or twenty feet, but which die away in a distance of fifty feet. Again, there are dome-like masses of quartz which are elliptical or oval in surface outline. In some parts at least these masses can be seen in contact with underlying rocks at a low angle, which would suggest that they are broad lenticular masses which have filled lateral fissures in the country rock. The...
Page 225 - While gold-bearing veins occur over a wide area and are often isolated, it is seen, from a number of those already discovered, that they occur in groups along certain lines. For instance, in Tisdale township there are at least three distinct areas where the fissuring has been most pronounced. One such area extends from the southeast end of Miller lake, on lot...
Page 205 - Northern Ontario Railway has been constructed from Iroquois Falls (on the main line), in a southwesterly direction to the town of Timmins, a distance of 33^ miles. Timmins by railway is 485 miles distant from Toronto. A number of townsites have been established in the area. The most important of these are: Porcupine, South Porcupine and Lakeview, situated on Porcupine lake; Schumacher, on Pearl lake; Timmins, west of Miller lake; and Mattagami, on the Mattagami river. Elevation of the Area In elevation...
Page 214 - In the township of Deloro there are bands of carbonate closely associated with bands of iron formation which may be traced for several miles in an east-west direction.
Page 210 - The Keewatin has a much greater distribution in the Porcupine area than the other members of the preCambrian, and it is also of more importance economically, since it contains the greater number of the gold-bearing veins which have so far been discovered. As in other parts of Ontario, the series is highly metamorphosed, and many rocks are so much altered as to give little evidence of their original character. However, much of the series can be seen to consist of basic and acid volcanics such as basalts...

Page 147 - Company, a new plant was installed, consisting o[ a 12-drill compressor, driven by a 200-hp motor. A 30-ton concentrating mill has been erected. The main shaft has been sunk to the fourth level, a depth of 250 feet. Levels have been run at depths of 65 feet, 140 feet, 185 feet and 250 feet. The vein has been developed for a length of about 500 feet, the drifts on each level having been run approximately this distance. A winze was sunk at a point 210 feet southwest of the shaft from the fourth to...
Page 60 - ... cross-head Explosive Accidents There were 16 fatalities resulting from the use of explosives underground and 2 on the surface, a total of 18 men killed. There were 36 men in all killed at the mines, so that explosives were responsible for 50 per cent, of the fatalities. In 1910 there were 10 men killed by explosives at the mines, or 27 per cent, of the total number killed. It is, therefore, evident that there has been an increase of nearly 100 per cent, in the fatalities from this cause. This...

It is thought that most of the gold has been deposited along with pyrite from the impure solutions which circulated In the minute fissures and crushed areas of the primary quartz of the veins. The quartz of No. 1 vein of the Hollinger mine shows numerous dark streaks in parts of It and often across the width of the vein. These are generally...
