Project Overview
The Yauliyacu mine is an underground zinc-lead-silver mine owned and
operated by Glencore. The mine has been in continuous production for
over 100 years. The Yauliyacu mill has a capacity of 3,600 tonnes per day.
Processing consists of conventional crushing, grinding and flotation, and is
capable of producing separate copper, lead and zinc concentrates that are
shipped for smelting.
Mineralization occurs in hydrothermal polymetallic veins (“Vetas”) and
disseminated orebodies (“Cuerpos”). The Vetas are up to 5 kilometres along
strike on surface of which 4 kilometres have been exposed underground
and have a known vertical range over 2 kilometres, and average 0.3 to 1.2
metres in width. At points where the veins converge, mineralization widths
can exceed 5 metres, contributing significant tonnage capacity to the mining
operations. Cuerpos were discovered in the late 1980s and have proven to
be an important part of the Yauliyacu reserve. Mineralization at Yauliyacu is
zoned vertically and laterally. Vertical zoning occurs with high grade silver
near surface and high grade zinc in the lowest levels of the mine. Despite its
long mining history, the mine has successfully replaced production through
ongoing exploration.
