Deposit Type

  • VMS
  • Footwall hosted
  • Breccia pipe / Stockwork


Summary:

The mineralization at El Domo shares most of the features of a VMS deposit (Franklin et al., 2005; Franklin et al., 1981; Large, 1992; Large et al., 2001; Lydon, 1996; Lydon, 1988a; Lydon, 1988b). VMS deposits are major sources of Zn, Cu, Pb, Ag, and Au, and can contain trace metals such as Co, Sn, Se, In, Bi, Te, Tl, Ga, and Ge.

Pratt (2008) was the first to document and describe a Kuroko-type VMS environment on the Project concessions. He established a lithostratigraphy for the Las Naves/El Domo area in which massive sulphide mineralization rests on a footwall sequence of rhyolite and dacitic autobreccias. He divided the sulphide mineralization into five types:
- Massive sulphides with indistinct texture. In some places, a fragmental texture can be seen within the sulphides, suggesting that they may be formed by the replacement of lapilli tuff.
- Sulphide-altered lapilli tuffs and peperites.
- Transported sulphide fragments within polymictic lapilli tuffs.
- Sulphide “pseudo”-fragments within polymictic lapilli tuffs. Rare, thinly laminated siliceous chert with banded sulphides.

The mineralised zone at El Domo is an intact, upright and only mildly disturbed Kuroko-type VMS deposit. As such, it displays the characteristic zoning of the model type from the underlying feeder pipe area through vertical and lateral variations upward to the abrupt termination of the massive sulphides against the characteristic hanging wall grainstone mar ........


Mining Methods

  • Truck & Shovel / Loader


Summary:

The Project is planned as a conventional open pit operation with haul trucks, hydraulic excavators and loaders. The ore will be transported from the pit to its destination by truck; ore material will be loaded preferentially by wheel loaders and waste material will be loaded preferentially by hydraulic excavators. Ore material will either be sent directly to the plant ROM pad or to the ore stockpile which then would to be rehandled and sent to the mill at a later time. At the stockpile, the different ore material types (High Zn, Mixed Zn/Cu, and High Cu) will be stockpiled separately to enable blending. The mill has a capacity of 666 kt/y, of which a maximum of 15% High Cu material is accepted, until there is no longer sufficient supply of the other ore materials for blending.

Waste material will be sent to one of four destinations: the overburden stockpile, the saprolite stockpile, the tailings storage facility, or the waste rock facility. Overburden will be sent to the overburden stockpile, saprolite will be sent to the saprolite stockpile, and other waste material will be divided as required to stabilise the overburden and saprolite stockpiles, or to build the tailings storage facility. Additional waste material will be sent to the waste storage facility.

The mine will operate year-round, seven (7) days per week, twenty-four (24) hours a day with two (2) 12-hour shifts a day. Fifteen (15) days of weather delays are considered in the mine plan.
