The process plant is comprised of conventional crushing and grinding followed by cyanide tank leaching. Back end filtration is required to maximize water recycling (dry stack tailings) as well as a SART (sulfidation, acidification re-neutralization and thickening) circuit to re-generate cyanide back to the process and to produce a saleable Cu2S copper sulfide product. Water supply to the process plant is provided by a nearby seasonally charged water dam and high voltage grid power is provided by the local utility. Expansion capital includes the cost to increase the process plant capacity from 1,750 tonnes per day to 4,000 tonnes per day in year three.

The contract underground mining will involve long hole stoping and cemented paste back filling of the mined-out stopes. Approximately 10% of the underground feed to the process plant will be sourced in close proximity to historical workings. The open pit mining will be contracted and carried out by drill and blast followed by conventional loading and truck haulage to the waste rock storage facilities and the process plant.

A total of 585 drill holes totalling 93,591 metres were used in the MRE.
P&E collaborated with GoGold personnel to develop the mineralization models, estimates, and reporting criteria for the Resources at Los Ricos. Mineralization models were initially developed by GoGold and were reviewed and modified by P&E. A total of eight individual mineralized domains have been identified through drilling, surface and historical underground sampling. The modeled mineralization domains are constrained by individual wireframes based on a 0.30 g/t AuEq cut-off for low-grade domains or 3.0 g/t AuEq for high-grade domains.
Mineralization wireframes were used as hard boundaries for the purposes of estimation.
A three-dimensional sub-blocked model, with 3m x 3m x 3m parent and 1m x 1m x 1m sub blocks, was used for the Mineral Resource Estimate. The block model consists of estimated Au, Ag and Cu grades, estimated bulk density, and classification criteria. Au and Ag equivalent block grades were subsequently calculated from the estimated Au, Ag and Cu grades.
Sample assays were composited to a 1 m standard length. Au and Ag grades were estimated using Inverse Distance Cubed weighting of between 1 and 12 composites, with a maximum of 2 composites per drill hole. Composites were capped prior to estimation by mineralization domain. Composite samples were selected within an anisotropic search ellipse oriented down the plunge of identified high grade trends.
Individual bulk density values were applied to mineralized domains separately and were statistically determined using 4,516 measurements taken from drill holes.
Classification criteria were determined from observed grade and geological continuity as well as variography. Measured Mineral Resources are informed by 3 or more drill holes within 30 m; Indicated Mineral Resources are informed by 2 or more drill holes within 60 m.
P&E is of the opinion that the Mineral Resource Estimates are suitable for public reporting and are a reasonable representation of the mineralization and metal content of the Los Ricos Deposits.
