The Cerro Caliche deposits are considered a Low Sulfidation Epithermal Precious Metal mineral deposit type as are the nearby Mercedes (Burtner, 2013) and Cerro Prieto (Giroux, Bain, 2013) gold mines. A working field model adapted includes field identifiable vein textures in quartz veins which have been adapted to the model. Textures suggesting boiling include lattice and bladed, which developed in partial quartz replacement of carbonate minerals along cleavage planes showing an indication of boiling that produces local acidic conditions. Adularia is also tentatively identified by its pink colored vein material which is also indicative of boiling fluid deposition. Also present are numerous bands of coarse to fine quartz in near rhythmic wall parallel bands that also surround fragments in the vein. The veins of the western side of the property, located near to and west of the Zorillo veins, are formed of white glassy quartz that do not contain more than geochemically anomalous gold (less than 50 ppb Au).

Detailed structural geological mapping and analysis completed in 2021 on the central portion of the Project concludes that the main trend of quartz veins is oriented north 20-50° west (Azimuth 310- 340°) with a secondary quartz vein system oriented north 30-50° east (Azimuth 30-50°). Identified faults show a similar orientation to the main veins trend, implying faulting activation along veins plains.

The long-term open pit mining evaluation for the Cerro Caliche Project will provide a nominal rate of 8,000 mtpd for the initial two years of production with an increase to15,000 mtpd for the remaining Run of Mine (ROM) and average 60,239 ounces mined per year over seven (7) years and three and a half months for a total of 446, 959 ounces mined. The overall waste/Mineralized Material ratio was calculated at 2.08:1 from a total of 98.9 Mt of rock mined, of which 66.8 Mt is waste and the remaining 32.2 Mt is leach feed.

Assumed open pit mining methods will use front-end loaders and hydraulic excavator to load haul trucks for waste and mineralized material haulage. Mining activities will include site clearing, removal of growth medium (topsoil), free-digging, drilling, blasting, loading, hauling, and mining support activities.

Material within the pit will be generally blasted on a six m high bench. The stripped waste material will be placed in assigned dumps and lower-grade mineralized material will be placed into a designated stockpile area or areas as needed during operations despite there being no strategic stockpiling in the Life of Mine (LOM) production schedule.

The mine fleet equipment is assumed to be provided by the mining contractor. The exact fleet will be determined at the time of operation.

The mine will be scheduled to operate 360 days per year, with five days scheduled for non-operation (Scheduled Loss= SL); Utilized t ........

The plant design is now based on a nominal 8,000 tpd (Years 1 and 2) and nominal 15,000 tpd (Years 3 through 8) of mineralized material more with average grades of 0.41 g/t Au and 4.05 g/t Ag. The process plant flowsheet design comprises of three (3) stage conventional crushing, material handling of crushed product and loading onto the lined heap pads. Solution ponds and pumping system will allow for irrigation of loaded mineralized material and subsequent collection of the pregnant solution. The pregnant solution will be pumped to two (2) trains of carbon in column tanks for loading of the gold and silver onto the carbon. Standard carbon in column processing will take place in terms of carbon advancement, carbon addition, carbon recovery, and bagging for shipment.

The Cerro Caliche Project does not plan currently to operate carbon stripping, electrowinning, and doré refinery at the plant. The loaded carbon will be shipped to North American carbon refiners were the gold and ........
