In 1901, the addition of two more furnaces increased daily capacity to 1,500 tons. By that time, the
underground mining had changed to the
room and pillar method to create
stopes which avoided the extensive timbering associated with the
square set method. In 1903, three small
steam shovels worked surface operations producing half the mine's production, being one of the earliest attempts at
open-pit mining in BC. Mine acquisitions and improvements included the Granby car, two giant steam shovels, two
saddle tank steam locomotives, and bunkers and loading facilities for the
Great Northern Railway (GN) line, which arrived in 1905. Gentler grades allowed heavier trains. Augmented by rate cutting, GN quickly replaced CP in hauling most of the mountain's ore. The
blister copper produced by the smelter went to the Nichols Chemical Company in
Brooklyn,
New York for further refining. In 1902, Miner divested his Granby interests. Graves in liaison with GN's
James J. Hill sought control, but
William H. Nichols acquired a majority interest in 1904. By 1906, the Knob Hill and the Old Ironsides workings joined underground to become a huge single network called the Granby mine, which spread into the Victoria claim that year. By 1908, Granby Consolidated owned 35 claims on the mountain, and smelter processing peaked at 1,178,853 tons, including ore from more distant mines. A
narrow gauge railway moved ore throughout the smelter. On the mountain, the Curlew and the Gold Drop mines were acquired in 1909 and the Snowshoe in 1913. Augmented infrastructure increased daily capacity to 3,400 tons, creating the largest copper smelter in the
British Empire and second largest in the world. High copper prices during
World War I prolonged the Phoenix operations. Mining ended in June 1919. By year end, the mine equipment was removed, the portals dynamited, and the railway tracks lifted. ==Map==
