On April 4, 1899, the American Smelting and Refining Company was chartered in the state of New Jersey. This great industrial
combine, usually known as ASARCO and frequently referred to as the smelting trust, had consolidated a number of American smelting
concerns with production plants east and west of the Mississippi. At its inception, ASARCO controlled 2/3 of America's smelting
and refining capacity, although several major firms remained independent of its ownership. Two years later, a second merger
took place which brought M. Guggenheim's Sons into the company, absorbing a principal competitor. In turn, Meyer Guggenheim's
sons took control of ASARCO after the merger and directed the company's continued expansion. ASARCO's plants dominated much
of the Rocky Mountain smelting industry in the early twentieth century, although the severe decline in silver, lead and copper
prices which followed the Panic of 1907 and persisted until American entry into World War I forced it to curtail many operations.
