Mine Life16 years (as of Jan 1, 2022)
Copper World Complex in Arizona includes the recently discovered Copper World deposits along with the Rosemont deposit.

The PEA contemplates a two-phased mine plan with the first phase reflecting a standalone operation with processing infrastructure on Hudbay’s private land and mining occurring on patented mining claims. Phase I is expected to require only state and local permits and reflects a 16-year mine life. Phase II extends the mine life to 44 years through an expansion onto federal land to mine the entire deposits. Phase II would be subject to the federal permitting process.

Deposit Type

  • Porphyry
  • Skarn


Summary:

The deposits are located in the Laramide belt, a major porphyry province that includes a number of other world class deposits. Mesozoic subduction and associated magmatism and tectonism in the southwestern United States and northern Mexico, generated extensive and relevant porphyry copper mineralization.

The Project deposits consists of copper-molybdenum-silver mineralization hosted quartz monzonite porphyries and in skarn that formed in the Paleozoic rocks as a result of the intrusion of quartz latite to quartz monzonite porphyry intrusions. Genetically, skarns form part of the suite of deposit styles associated with porphyry copper centers. The skarns were formed as the result of thermal and metasomatic alteration of Paleozoic carbonate and to a lesser extent of Mesozoic clastic rocks. Near surface weathering has resulted in the oxidation of the sulfides in the overlying Mesozoic units at the East deposit and in the near surface Paleozoic units at the Copper World deposits.

Mineralization occurs mostly in the form of primary (hypogene) copper, molybdenum and silver bearing sulfides, found in stockwork veinlets and disseminated in the altered host rock at depth. Near surface, along structural zones, and in quartzite units oxidized copper mineralization is present. The oxidized mineralization occurs as mixed copper oxide and copper carbonate minerals. Locally, enrichment of supergene chalcocite and associated secondary mineralization are found in and ben ........


Mining Methods

  • Truck & Shovel / Loader


Summary:

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 ........
