The Invicta Gold Project geology comprises mainly mafic volcanic rocks of the Calipuy group that overlie diorite, tonalite and granodiorite of the Paccho pluton, an intrusive suite that is part of the Huaura plutonic complex (Coastal batholith). Diorite and granodiorite of the Paccho intrusion are exposed in the southwest and western portions of the Invicta Gold Project. These generally comprise massive, weakly to moderately silicified rocks, with strong kaolinite, limonite and hematite altered rocks associated with mineralized zones.

Mineralized veins at the Invicta Gold Project have many of the characteristics of epithermal vein systems. Buenaventura Ingenieros S.A. (2010) concluded on the basis of fluid inclusions studies, which indicated multiple fluid populations and homogenization temperatures between 250 and 400 degrees Celsius, that mineralization at the Invicta Gold Project was mesothermal. However, field observations, including the style of veining, alteration, and the presence of open-space, vuggy textures are more in support of epithermal-style veining. The results obtained by Buenaventura Ingenieros S.A. (2010) may be explained by a depositional process controlled by fluid mixing and the cooling of the hydrothermal system associated with multiple stages of mineral deposition over a protracted period of time.

Mineralization
Mineralization is closely linked to the first stage of deformation, and occurs in three principal settings:
• ........

The geotechnical characterization of the mineralized deposit, the wall-rock competency and the geometric shape lends itself to a sublevel long hole stoping mining method with unconsolidated waste rock backfill. This method typically responds well for obtaining a high extraction ratio, controlled dilution and reasonable to low operating cost.

Longhole drilling will be undertaken by down-the-hole hammer drills with an on-board compressor. Longhole stopes will be blasted utilizing ANFO with standard blasting techniques.

The blasted material will be mucked from the 3400- extraction level utilizing 4 cubic yard LHDs (fitted for remote use). The ore then will be dumped directly into 20 tonne haulage trucks. The trucks will then transport the material from the adit to an off-site mill processing facility.

The lower portion of the stopes will be 30 m high (sill to sill) and mined from the 3400 Level with up-hole drilling and from 3430 Level with down-hole drilling. All other levels, from 3445 to 3505 Level are 15 metres in height and will be down- hole drilled.

The total height of the stopes will be estimated at 130 metres, with a length of 40 metres, and a width of 4 to 14 metres. All stopes will be separated by rib pillars and filled with available development waste rock. The availability of backfill may not always be ready within the mine cycle therefore these designed rib pillars in-between stopes will allow for further support if th ........
