Toquepala Discovery and Exploration
Copper mining in southwestern was carried on sporadically since the end of
the 19th century, and there are brief references in geographical literature
of the time to copper occurrences in the general area of Toquepala and
Cuajone. Narrow oxide and enriched sulfide veinlets were exploited on a very
limited scale, but the desert nature and difficult accessibility of the area
discouraged continued mining activities. Soon after the settlement of the
border conflict between Peru and Chile in 1929, interest was renewed in the
are and local residents started staking out mining claims. Prominent among
these were Juan Oviedo Villegas (Toquepala) and Julio E. Gianella (Cuajone).
