1H19
-
Exploration intensified at the Rosario Transversal fault as well as to the West of the San Ramón vein, to identify further opportunities in the Ciénega District.
-
1st phase of the construction of the third tailings dam advanced, now expected to be concluded by year end.
-
The installation of a high compact thickener to optimise water consumption advanced according to plan.
-
Increased development at Taspana and Ciénega.
3Q19
-
Quarterly gold production increased 18.5% vs. 2Q19 while quarterly silver production decreased 5.0% vs. 2Q19 driven by the ore grades. This was in line with the mine plan, as we extracted a higher proportion of material from the eastern zone of the district with higher gold content and lower silver content.
-
Quarterly gold and silver production decreased 2% and 10% vs. 3Q18 respectively driven by lower grades in line with the mine plan.
-
Year to date gold production decreased 7.1% vs. YTD18 driven by a lower ore grade resulting from the natural depletion of high ore grade areas in the deeper levels at Las Casas and East Taspana. A lower recovery rate further impacted the YTD19 gold production.
-
Expected gold ore grade in 2019 remains in the range of 1.60-1.70 g/t and silver ore grade is still anticipated to be between 150-160 g/t.
2H19 Priorities
- With the results of this exploration campaign, resources and reserves estimates will be updated and a new preliminary economic assessment will be produced.
- 2nd phase of the construction of the third tailings dam expected to be concluded in 2020.
- Secure permits and begin engineering for the fourth tailings dam.
