The Korea Mine Rehabilitation and Mineral Resources Corp. (KOMIR) held a 77.01% equity interest in the Boleo project and is the operator of the project. A consortium led by the KOMIR, comprising the Company, LS-Nikko Copper Inc., Hyundai Steel, SK Networks Co. Ltd. and Iljin Materials Co., Ltd., together holds a 93.09% interest in the project.
Camrova owns 6.91 % of the Boleo copper mine in Mexico, which is majority owned by KOMIR.
Minera y Metalúrgica del Boleo, S.A. P.I. de C.V. is a consolidated subsidiary of the KOMIR and is the operator of the Boleo project.

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
- Strip mining (roll-over)
- Truck & Shovel / Loader
Summary:
The Boleo mine consists of several surface and underground mines under development.
For the development of surface mines, Minera Boleo uses open pit mining techniques and equipment, such as trucks, excavators and front-end loaders, for all its extraction of ore and waste.
The underground mining method at Boleo mine is short wall mining or strip mining taking into account geological conditions and the mined ore is brought to the surface by a conveyor belt system. Ore from both surface and underground mines is trucked to the crushing areas of the plant for further processing.
