The cover was sent to the executive offices of the mining company in Lima whereas the mining establishment is in the mineral-rich Cerro de Pasco which is at an altitude of 4, 338 metres. The town of Cerro de Pasco was founded in 1771 and the region has been highly relevant to the Peruvian economy since the Spanish Colonial period on account of valuable lead, copper, gold, zinc and bismuth deposits. The town is northeast of Lima to which it is connected by rail and highway. Rich silver deposits were found as early as 1630, and for about two centuries it was one of the world's largest sources of silver. In the mining of copper, U.S. Capitol acquired important interests, founding the Cerro de Pasco Corporation (1902-1974).
The capital of Pasco Department is Cerro de Pasco and the entire region has a population of more than 600,000.
