DEPOSIT TYPES
The deposit was more recently classified by Arce-Burgoa and Goldfarb (2009), as being a deformed example of the Iron Ore Copper Gold (IOCG) association.

The two main deposits types present on the Don Mario Property are exemplified by the copper-dominated UMZ deposit that shows direct association with a large calc-silicate zone, and the gold-dominated LMZ deposit that occurs beneath the UMZ and shows direct association with shear-focused silicification, calcsilicate, potassic, and iron oxide alteration. The Las Tojas and Cerro Felix deposits are similar in style and association with the LMZ, but no substantive additional examples of the UMZ style have been identified on the Property to date.

Tailings Storage Facility (TSF)
Tailings are not a “deposit type” in the conventional sense but in this case, for the purposes of considering Don Mario’s TSF content a Mineral Resource, they are described as an accumulation of loose material with grain size finer than sand, mainly composed by silt size material and less than 20% of clays. The tailings material humidity can vary from 20.8% to 51.4% (Sanchez et al., 2018).

The executed laboratory tests evidence that the tailings can be grouped into fine tailings and coarse tailings, classified respectively as silty sands and silts with low plasticity with the following characteristics:
- The coarse tailings, classified as silty sands, have a field density of 1.468 g/cm3 to 1.712 ........

The Don Mario Property currently does not have any in-situ Mineral Resources or Mineral Reserves. The only Mineral Resources or Mineral Reserves currently on the Property are hosted in five of the six oxide stockpiles and in the tailings contained within the TSF.

Tailings Reprocessing Project (TRP)
No mining plan is presented for the TRP because it is not sufficiently advanced for the development of a mining plan.

Oxide Stockpiles
The planned mining method for the oxide stockpiles consists of loading conventional end dump trucks with either a wheel loader or an excavator on a mucking schedule from various oxide stockpiles, in order to achieve the desired plant feed blend after haulage from stockpile locations to the crusher area. The goal is to obtain an average blending of Au, Cu an Ag grades with oxide gangue minerals that will ensure optimal metal recoveries.

Loading and transportation activities are planned for daily 12 hour shifts. The Company targets delivering a monthly average of 59,000 tonnes to the blended stockpile. The blended ore will come all thee various OSPs and be blended to achieve the proper mix of grade and oxidized gangue minerals to maximize recoveries. The Company expects full production to take a four month ramp up period.
