Copper Mines - Homestake Copper Company

Metal Trade, Copper Industry and Trade, Copper Mines and Mining, Sign and Signboards, Woody Plants, Trees While most "thermometer" signs register success by rising, that of the Homestake Copper Company of Calumet shows progress by falling. The sign is an indicator of the Centennial No. 6 mine dewatering projects, showing the original level of the water in the mine and its removal to date. The 31st level was reached this past Saturday. Bailing began April 2 when the water was at the 27th level. The thermometer in this case is the mine's shaft. [Photo of the sign indicating the progress made in removing water from the mine.]
