Field evidence suggests that the Igor project mineralization belongs to the epithermal type of gold-silver deposit (Guilbert and Park, 1986). In general, epithermal gold-silver deposits are composed of structurally or stratigraphically controlled disseminations or veins that form in a shallow environment (less than or about 1.5 km) and are hosted by volcanic or sedimentary rocks. The mineralization is dominated by gold and silver but can contain variable amounts of copper, lead, and zinc.

Igor project mineralization occurs within four primary target areas: Callanquitas, Domo, Tesoros, and Portachuelos. Mineralization within the property often occurs at the transition zone from Chimú up into the Santa and Carhuez rocks. There is a spatial association of dacite porphyry dikes emplaced within structural breccias with both structural and manto-style mineralization.

The Callanquitas area, which is on the northwest side of the Igor anticline, is the focus of the current resource estimate and pre feasibility technical analyses. Domo and Tesoros, within the east and southeast sides of the anticline, respectively, have had limited drilling and both are areas of minor artisanal mining activity. Portachuelos is an exploration target on the southwest limb of the anticline on trend south of Callanquitas.

Callanquitas Veins
The Callanquitas veins (Callanquitas Este, Callanquitas Oeste and Cianuro) occur within a north-south striking zone of multiple, a ........

The Igor mine will be accessed via two declines and a system of internal ramps.

The modified cut and fill mining method will start by mining all the capital development on alevel including the decline, station levels, and raises. After the capital development for a level is complete, the access drive will be mined from the station level to the ore drive at a -12.5% grade. The ore drive runs along strike of the orebody. After the ore drive is mined out, the first lift will be mined by drilling up holes into the back and blasting down. The material will be moved out of the drift via an underground loader and trucks. After the first lift is mined out, the ore drive will be filled with waste rock via an underground loader and trucks. The access drive will then be adjusted to access the first lift. This process will continue until the sill pillar is reached .

The level layout consists of a decline, level station, exhaust raise, intake raise, level access, ore drives, and stopes. The raises will also be used as a material pass system. The access drift is designed at -12.5% grade. The access drift will be adjusted upwards after each lift is mined and filled. The resulting access drift will be at +12.5% grade. The decline is also designed at -12.5% grade.

All mining, including production and development, will be done by mining contractors who will provide the required mobile equipment.
