The mineralization identified to date on the property is consistent with a supergene enrichment blanket hosted in a sandstone-quartzite package of Soraya Formation associated with an Andean-type copper- molybdenum porphyry system.

The most important mineralization encountered to date on the property is a tabular body of fracturecontrolled and disseminated chalcocite and chalcopyrite with minor molybdenite-coated fractures overlain by a barren, leached zone of variable thickness. The tabular zone strikes 50 degrees and dips 20 degrees to the east over an area 1.2 kilometres long and 1.2 kilometres wide. The supergene chalcocite mineralization has a true thickness of 40 to 80 metres. Associated with the chalcocite mineralization is weak sericitization, chloritization, and silicification of arenite and quartzite. The strongest chalcocite mineralization is associated with brittle faults. Below the chalcocite mineralization, low grade disseminated chalcopyrite, bornite, and molybdenite mineralization occurs. Altered, weakly-mineralized porphyritic felsic intrusives are associated with the hypogene mineralization. Unaltered, unmineralized porphyritic dikes cut the mineralization.

The most economically significant mineralization encountered to date on the property is fracture- controlled and disseminated chalcocite. The chalcocite occurs as:

1. Sooty or scaly coatings 1 millimetre wide, filled to partially open fractures;
2. Sooty coatings on ........

The mining operations proposed for the Antilla project are typical of open pit, truck-and-shovel heap leach mining methods for year-round operations in mountainous terrain. Truck-and-shovel mining operations are assumed to be completed by a contract miner utilizing their own mining fleet.

The mine operations are organized into three departments: mine maintenance, technical services, and direct mining. Mine maintenance accounts for the supervision and planning of the mine maintenance activities. Technical services account for the technical support from mine engineering, planning, geology, and surveying functions. Direct mining accounts for the drilling, blasting, loading, hauling, and pit maintenance activities in the mine.

Operations are assumed to run 365 days per year, 24 hours per day, seven days a week, on a 12-hour shift rotation.

The production schedule targets 20,000 tonnes/day of leach material, resulting in 7.3 million annual tonnes of crushed leach material placed on the leach pad. Marginally economic leach material is stockpiled to increase leach material grades. The stockpile is reclaimed in later years of the mine schedule when it is economically beneficial to do so. Mine waste rock is used to construct site infrastructure where applicable or is placed in the Rock Storage Facility to the west of the pit area.

The Antilla mining operations will be undertaken by contract miners who will supply and maintain their own fle ........

The Antilla Project will operate a conventional hydrometallurgical process consisting of a crushing plant, a valley-fill leaching plant, solvent extraction plant, and Electrowinning plant to produce grade-A copper cathodes.

Crushing Plant
The crushing plant considers a multi-stage circuit to reduce the ROM ore to approximately 100% minus 1” inch. The crushed ore will be stockpile, then loaded onto dump trucks and transferred to the heap leach plant using a front-end loader and 20 tonne dump trucks.

Heap Leaching
The valley-fill leaching operation will have capacity to receive approximately 120 million tonnes of ore over the 17 years of life of mine. The ore placed on the leach pad will be irrigated with diluted acid solution to transfer copper metal into the PLS. The bottom of the valley will be impermeabilized with a synthetic liner to collect all percolating solutions.

Solvent Extraction and Electrowinning
A conventional multi-stage sol ........
