Deposit Type

  • Manto


Summary:

The Boleo deposits occur within a Miocene rift zone basin and consist of a succession of fine to coarse clastic sedimentary rocks characterized by a number of coarsening upward cycles of deltaic deposited sediments. Faulting is common throughout the district.

The dominant faults are steeply dipping normal faults striking northwest and downthrown to the west by up to 200 meters (m). These offsets, combined with the easterly dip of the mantos, yield a stepwise configuration of the mineralized beds. Major faults are typically separated horizontally by several hundreds of meters, although lesser faults are common and are more closely spaced. The extensive faulting, with vertical offsets ranging from less than a meter to tens of meters, divides the project area into relatively small, irregularly-shaped blocks. The ground immediately adjacent
to fault zones is generally observed to be degraded, with little or no structural strength. The surface topography is highly variable and= consists of flat-topped mesa structures that are deeply incised by rugged, steep-sided arroyos. The depth of cover varies from zero to several hundred meters.

Copper-cobalt-zinc mineralization occurs throughout the Boleo District within clay-rich horizons or beds known as “mantos.” The mantos correspond to the lower units of similar stratigraphic sequences occurring in a repeated series. Each sequence consists of a general coarsening of the sediments from the base to the top. The ........


Mining Methods

  • Shortwall mining
  • Truck & Shovel / Loader
  • Continuous
  • Room-and-pillar


Summary:

The project is an underground and surface mining operation to provide run-of-mine ore to a fully integrated hydrometallurgical facility. Integrated underground mining which comprise short wall and room and pillar method using continuous miners along with small cuts open mining techniques are to be employed. The mine plan will be continuously optimized on the basis of resource update by additional drilling and operational condition with the aim of maximizing economics.
