Con Kelley had been a boy in Walkerville, Montana. More significantly, he had a solid knowledge of The Butte Hill. During the years he attended law school, he mapped the mines and orebodies of Butte. After his mentor, John D. Ryan died, Kelley waited through the rest of the Great Depression before stepping into the position of Chairman of the Board for The Anaconda Company (The Company). That move was essential to increasing production from peacetime rates to the pitched levels needed for burying the Axis Powers in American guns, equipment, ships and ammunition. A lend-lease program with the United Kingdom (U.K.) and the Union of Soviet Socialist Republics (U.S.S.R.) took shape by March 1941. That’s when Roosevelt proclaimed the United States (U.S.) as the “Arsenal of Democracy.” The U.S. was starting to produce more fighting implements at a modest rate. Tanks, for example, were coming off assembly lines at the rate of 115 a month, while Joseph Stalin was begging for 500 per month.
As German submarines started interrupting normal supplies of chromium, The Company opened the Benbow and Minatt-Sampson chrome mines in Stillwater County and began producing 75,000 tons of chromium concentrate a month.
The crying need for manganese and the uncertainty of interrupted imports by submarine interdiction had already caused The Company to reopen Butte’s Emma and Travonia mines. Each day from June 1941, they produced 2,240,000 pounds of pink rhodochrosite mineral, which was 42 percent manganese, until the demand for manganese abated at the end of WWII. From this lower grade ore, the reduction plant in Anaconda, Montana, annually produced 224,000,000 pounds of 60 percent manganese nodules. Butte and Anaconda eventually produced 537,600,000 pounds of domestic U.S. manganese, enough at 12.5 pounds of hardener and alloy per ton of iron to enable production of more than 43 million tons of U.S. steel. This level of production represented more than 98 percent of the total manganese produced inside the U.S. In 1942, U.S. manganese consumption rose more than six-fold to more than 990,000 metric tons or 2.182 trillion pounds, of which nearly 29 percent was domestic, with the percent growing toward 40 percent. In democracy’s mighty arsenal, Montana’s mines in Butte were critical to the war effort. In the mid-1940’s, the Northern Pacific Railroad published in leading newspapers and magazines that had Butte and its surrounding area been captured or destroyed by enemy forces in 1941, it might have crippled the U.S. war production effort. “The mines in Butte and vicinity worked a miracle of manganese production, using ‘pink ore,’ a former waste material. This manganese has been a mainstay of America’s armament industries.”
And, it wasn’t just manganese for hardening iron into steel. In 1942, for example, while Butte’s miners were annually drilling, blasting, mucking and filling boxes with rocks containing 144 million pounds of manganese, they were also mining 47 million pounds of zinc, and 250 million pounds of copper. As byproducts they also removed 10,000 ounces of gold and 6 million ounces of silver. During all of World War II, as some of the Blue Stars in the windows of hundreds of Butte families turned to Silver for someone being wounded, and Gold for someone deceased, 115 Butte miners were killed while working underground.
Butte’s 12.5 pounds of manganese per ton of steel became part of America’s 29,497 tanks and self-propelled guns, 257,390 artillery pieces, including anti-aircraft and anti-tank guns, 105,054 mortars, 2,679,840 crew-served machine guns, 11,750,000 rifles, 1,956,000 sub-machine guns, 2,832,311 trucks, 99,950 fighter planes, 62,444 light and medium bombers, 35,366 four-engine bombers, 3,918 reconnaissance planes, 23,929 transport planes, 57,623, training and miscellaneous planes, 141 ships that carried aircraft, 27 of which were aircraft carriers over 100,000 tons, 8 battleships, 48 cruisers, 349 destroyers, 498 escort corvettes and frigates and 203 submarines.
Besides 12.5 pounds of manganese for every ton of steel, those ships need cadmium paint on their hulls to keep from rusting and copper for hundreds of components. For example, “Each Iowa class battleship contained 3,058,000 pounds of copper. Just one large bronze propeller used 50,000 pounds, heavy cruisers needed 1,407,000 pounds and light cruisers needed 1,279,000 pounds. Aircraft carriers needed 2,861,000 pounds, while their escorts each required 622,000 pounds. Destroyers contained 463,000 pounds, submarines needed 348,000 pounds and submarine chasers used 58,000 pounds. Even torpedo boats like John F. Kennedy’s PT109 each required 18,000 pounds. And, that copper requirement did not include their big guns for hammering shorelines and beaches. Each 6-inch, 8-inch and 16-inch gun mount and turrent needed 18,800, 29,100 and 66,100 pounds of copper, respectively.
Then there was the zinc required with copper for some aircraft. P-38 Lightning fighters needed 1384 pounds of copper and 72 pounds of zinc, P-39 Airacobras, 938 and 25 pounds, P-40 Kitty Hawks, 1001 and 51 pounds, P-47 Thunderbolts, 660 and 87 pounds, P-51 Mustangs, 681 and 125 pounds, B-17 Flying Fortress bombers, 2958 and 181 pounds, B-24 Liberator bombers, 3025 and 132 pounds, B-25 Mitchell bombers, 2010 and 193 pounds, B-26 Marauder bombers, 1545 and 205 pounds, A-20 Havoc bombers, 782 and 95 pounds, and each C-47 or DC-3 Air Transport required 1569 pounds of copper and 95 pounds of zinc.
What about ammunition?
Ammunition consumed one third of all U.S. copper production. Each million cartridges used 28,000 pounds. A single fighter plane fired 2500 bullets in 15 seconds, A flight of 50 planes could fire a half million cartridges in a minute. One hour of firing a single 105-mm cannon, 36 to an armored division, hurled 1000 pounds of copper. The weight of copper in naval gun shells from each gun, increasing in size was 15.2, 27 and 70.5 pounds. Without copper, no torpedo or depth charge could even function.
As far as ground combat machines used in the Battle of the Bulge, a 90-mm anti-aircraft gun needed 80 pounds of copper in the gun tubes, 400 pounds in the recoil mechanism, and 1,000 pounds in the carriage. Each 81-mm mortar carrier, 105-mm self-propelled howitzer, 75-mm self-propelled gun, and 155-mm gun without vehicle, respectively, needed 164 pounds, 250 pounds, 190 pounds and 1350 pounds of copper. One .50-caliber machine gun required at least 10 pounds of copper, and the 7,000 Garand M-1 rifles in a typical triangular division each, like the one fired by Frank Vukassin, used 3/10’s of a pound. Each of the 300 light tanks and 200 medium tanks in a typical armored division used 500 and 900 pounds of copper respectively.
The Anaconda Company’s mines, smelters and refineries in Montana produced 51.26 percent of the total increase of U.S. copper production during WW II. By 1942, 80 percent of Butte’ miners were working six days a week and opting for higher personal production rates as contract miners. Butte’s mines were operating seven days a week to eventually produce 6,800,000,000 pounds of copper during WWII. Adding to this the 1,513,000,000 pounds of finished copper being produced The Company’s other mines at Mountain City and Battle Mountain in Nevada, employees of The Company produced one-third of the copper available to the U.S. for prosecuting WWII.
To help accomplish these massive tasks, underground in the mines of Butte, Montana, The Company erected trees of “No Smoking” signs in sixteen languages.
