Deposit Type

  • Epithermal
  • Sediment-hosted


Summary:

The Shahuindo deposit formed in a predominantly intermediate-sulfidation epithermal system of probable Miocene age. Distinguishing characteristics of an intermediate-sulfidation environment include mineral assemblages indicating a sulfidation state between those of high and low sulfidation types, relatively high total sulfide content of five to 10 percent in the sulfide environment, presence of silver sulfosalts, and association with andesitic to dacitic volcanics. Magmatic associated fluids are implied. There is no evidence of adularia at Shahuindo, thus ruling out a low-sulfidation environment. There are some observances of enargite at depth, suggesting a mixed intermediate- to high-sulfidation system.

Mineralization at Shahuindo is best described as an intermediate-sulfidation epithermal system, though high-sulfidation mineralization occurs at depth and in the core of hydrothermal breccias. Oxidation of mineralization extends to a depth of 150m below surface. In the weathered oxide facies, gold and silver are associated with the presence of jarosite and hematite. In the underlying fresh sulfide facies, gold is typically extremely fine grained with the related mineral species not yet identified.

The principal zone of mineralization in the Shahuindo district occurs in a belt between two large-amplitude regionalscale folds, the Algamarca anticline and the San Jose Anticline. The Algamarca anticline is upright and symmetrical with amplitude of at least 400m, whereas the San Jose fold is an asymmetric, overturned, northeast-vergent fold with a shallowly dipping axial surface and amplitude of at least 300m. Important structural elements include fold limbs and fold axial surfaces, fold-related fractures, faults and related extension fractures, breccia dikes and irregular bodies, and igneous intrusive contacts.

Both structure and lithology control the location, shape, and orientation of the mineralization. The mineralization is hosted within the siliciclastic sandstone-dominant Farrat Formation and the underlying sedimentary Carhuaz formation. These sedimentary rocks have been intruded by at least three felsic stocks which tend to be located along faults and cores of anticlinal structures. In addition, the metallurgical recovery of gold is affected by lithology with the identification of five primary geometallurgical domains based on the relationship between lithology and grain size and gold recovery. Modelling the distribution and occurrence of lithologic units / geometallurgical domains is critical to mine planning.


Mining Methods

  • Truck & Shovel / Loader


Summary:

The Shahuindo Mine is an open pit heap leach operation. The mining method used is a conventional drill/blast, shovel and dump truck operation.

The mining schedule at Shahuindo consists of two phases. Phase 1 entails mining higher grade starter pits providing ROM material to the Phase 1 leach pads in 2016 and 2017; the average mining rates in 2016 and 2017 are approximately 15,800 tonnes of ore per day and 15,300 tonnes of ore per day, respectively. Phase 2, beginning in 2018, includes the addition of a crushing and agglomeration facility, increased plant capacity and an additional leach pad. The mining rate in Phase 2 increases production to meet the Phase 2 plant capacity of 36,000 tonnes of ore per day, which will require an upgraded mining fleet.

Summary:

Gold from the Shahuindo Mine is extracted from the ore via heap leach and then processed by carbon-in-column ADR operations.

Maintaining heap permeability and minimizing channeling at higher heap heights in the life of-mine leach pads will require crushing and agglomeration of a significant portion of the ore. The first stage of crushing and agglomeration is designed to operate at a nominal 12,000 tonne per day rate, with ore delivered to the leach pads via grasshoppers and overland conveyors. The 12,000 tonne per day crushing-agglomerationconveyance circuit is in the final stages of commissioning and has been placed into operation. Commissioning of the expanded crushing and agglomeration circuit to 36,000 tonnes per day is expected to commence in mid-2018. The Company continues to conduct further test work on the agglomeration circuit to optimize the efficiency of the circuit and the maximum leach pad height.

After the ore is placed on the leach pad, a diluted c ........
