Deposit Type

  • Vein / narrow vein
  • Skarn


Summary:

Mineralized Zones
The Camino Rojo deposit comprises intrusive related, clastic sedimentary strata hosted polymetallic gold, silver, arsenic, zinc, and lead mineralization.

Three stages of mineralization, including two styles of high-grade gold-silver mineralization, have been observed in the Camino Rojo deposit:
• Stage 1 K-metasomatism (adularia)-pyrite – K-metasomatism with disseminated pyrite replaced the mudstone, siltstone and fine-grained sandstones in the Caracol Formation. Mineralization is typically low-grade gold with 0.1- 0.4 g/t.
• Stage 2 Intermediate Sulphidation (“IS”) veins – IS veins with pyrite-arsenopyrite-sphalerite±galena, calcite and minor quartz. Moderate to high grade gold (0.4 to +4.0 g/t), high zinc grades (0.5 to >2.0% Zn) and high values of As, Pb and Ba, with variable Ag.
• Stage 3 LS veins – colloform banded quartz veins, drusy-coxcomb quartz veins, and quartz-cemented, polymictic hydrothermal breccia with pyrite-galena-sulphosalts, adularia and electrum. Moderate to high gold grades (2.0 to 15.0 g/t) with high silver (100 to 500 g/t), and high As and Sb values, but variable to low Zn, Pb, and Ba values.

At hand specimen scale, mineralization is controlled by bedding and fractures. The sandy and silty beds of the turbidite sequences of the Caracol Formation are preferentially mineralized, with pyrite disseminations and semi-massive stringers hosted within them, presumably due to higher syn-mineralizing ........


Mining Methods

  • Truck & Shovel / Loader


Summary:

Mine operations will consist of drilling medium diameter blast holes (approximately 17 cm), blasting with explosive emulsions or ANFO (ammonium nitrate/fuel oil) depending on water conditions, and loading into large off-road trucks with hydraulic shovels and wheel loaders. Resource will be delivered to the primary crusher and waste to the waste storage facility southeast of the pit. There will also be a low-grade stockpile facility to store marginally economic Mineral Reserves for processing at the end of commercial pit operations. There will be a fleet of track dozers, rubber-tired dozers, motor graders and water trucks to maintain the working areas of the pit, waste storage areas, and haul roads.

A mine plan was developed to supply Mineral Reserves to a conventional crushing and heap leach plant with the capacity to process 18,000 tpd (6,570 ktpy). The mine is scheduled to operate two 10-hour shifts per day for 365 days per year.

Eventually, mining will be conducted below the water table, probably during Year 4 of commercial operation. Estimates of pit dewatering requirements have been prepared for cost estimation purposes. These are based on the median expected water in-flows. Additional hydrogeological studies underway will allow a better estimate of the pit dewatering requirements.

The recommended slope design is based on a 38° IR angle for the post mineral rocks on the east side of the pit. The south wall is designed at a 53° IR a ........

Reserves at December 31, 2022:
Mineral Reserves are based on net smelter returns (“NSR”) cut-offs that vary by time period to balance mine and plant production capacities. They range from a low of $5.69/t to a high of $10.00/t.

Mineral Resources are based on NSR cut-off grades of $5.69/t for leach material and $13.71/t for mill material.
