The Copper World deposits consist of seven deposits, including Bolsa, Broad Top Butte, West (formerly referred to as Copper World), Peach, Elgin, South Limb and North Limb. The Rosemont deposit has been renamed the “East” deposit.
The mine will be a traditional open pit shovel and truck operation with bench heights of 50 and 100 foot, and 255- ton capacity haul trucks for material and waste movement.
Mining operations will use large-scale mine equipment including: 10-5/8-in. diameter rotary blast hole drills, 44 yd3 class hydraulic shovel, 36 yd3 front-end loader, and 255-ton capacity off-highway haul trucks.
The Peach-Elgin, Broadtop Butte and West pits will measure 5,600 ft on average in diameters with an average depth of 520ft while the East final pit size will measure approximately 8,200 ft in diameter and have a depth of approximately 2,250 ft. Other facilities that support the project are the Process Plants, Leach Pad, Waste Rock Facility (WRF) and Tailings Storage Facility (TSF).
The mining sequence follows a two-phase approach, where the first phase considers the exploitation of the pits within requiring only state and local permits of operation for 16 years (plus one year of pre-stripping). During this period, all waste, tailings and leach pads are disposed within the limits of Hudbay’s private land properties. After this first phase, it is assumed that all necessary permits have been obtained in order to mine and deposit ........
