Camino Rojo Oxide Program:
The Company is seeking to define additional oxide reserves at the Camino Rojo Oxide Mine following confirmatory core drilling on the Fresnillo Plc’s (“Fresnillo”) property, located immediately north and adjacent of the Camino Rojo oxide mine open pit. While historical drilling indicates that mineralization continues across the property boundary onto the Fresnillo layback area, no ounces from this area are currently included in the Camino Rojo mineral reserve estimate. The planned 2,500m diamond drill program is designed to confirm and delineate mineralization located in the oxide pit layback and allow for a potential update of mineral resource and reserve estimations.
Camino Rojo Sulphide Program – Phase 2:
Following a successful core drill program in 2021, an 8,250m follow-up drilling phase is planned in 2022 on the Camino Rojo Sulphides. The 2021 program consisted of 6,079m across 14 holes on a 100-250m drill spacing at a south orientation. This program confirmed wide zones of higher-grade gold mineralization within the sulphide deposit while also providing material for new metallurgical study, which remains in progress. The 2022 program will infill drill the deposit and reduce the spacing to 50-125m. This tighter drill spacing on the more optimal south orientation, combined with the extensive south to north historical drilling, is anticipated to reinforce the geological model and confirm continuity of wide zones of higher-grade gold mineralization. This drilling is expected to support an updated resource estimate for the Camino Rojo Sulphides, and the advancement of development planning and a Preliminary Economic Assessment targeted for year end 2022.
Camino Rojo Sulphide Phase 1 (2021) drilling highlights (previously reported):
- 2.38 g/t Au over 108m (Hole CRSX20-01)
- 2.63 g/t Au over 111m (Hole CRSX20-01A)
- 2.51 g/t Au over 58.5m (Hole CRSX20-01B)
- 2.11 g/t Au over 115.5m (Hole CRSX20-01C)
- 3.04 g/t Au over 64.6m (Hole CRSX20-01D)
- 4.47 g/t Au over 55.5m (Hole CRSX20-04A)
- 4.95 g/t Au over 55.5m (Hole CRSX20-04A)
- 2.10 g/t Au over 58.5m (Hole CRSX20-04B)
- 2.27 g/t Au over 87.0m (Hole CRSX20-04B)
- 3.26 g/t Au over 44.7m (Hole CRSX20-04C)
Camino Rojo Regional Exploration Program:
Prior to 2021, exploration had focused on defining and expanding the Camino Rojo deposit, with limited work outside the area of the currently defined deposit and infrastructure. In 2021, regional exploration focused on defining new exploration targets using detailed airborne magnetic drone survey, induced polarization (IP) survey, and multi-elements soil geochemistry. In addition, a 9,146m, 284-hole regional rotary air blast (RAB) Cover-Bedrock Interface (CBI) program, with drill fences spaced at 1,000m and drill holes spaced at 500m along the fence, was completed to directly sample bedrock below shallow cover. Encouraging results of anomalous gold were intercepted, including 3m at 1.94 g/t Au and 44m at 0.08 g/t Au, 7 km northeast of Camino Rojo (see figure below). See Appendix for a summary of the anomalous results from the RAB CBI 2021 drill program.
As a result of this work, several exploration targets were defined along the Camino Rojo trend and south of the Camino Rojo Oxide Mine. These new exploration targets are hosted in rocks of the Caracol or Indidura formations, are supported by geophysical and/or geochemical anomalies, and are located at the intersection of NW-SE structures associated with the San Tiburcio Fault Zone and NE-SW trending structures on or paralleling the Camino Rojo trend. In 2022, drilling will occur on priority targets and new target generation work will also continue. A 10,000m RC drill program is planning to test the priority targets along the Camino Rojo trend and south of the Camino Rojo Oxide Mine. New deposit discovery remains the objective and this could include oxide deposits that support extension of the mine life at the Camino Rojo Oxide Mine or be additional sulphide deposits that strengthen and expand the already impressive sulphide endowment.
