Including the Saucito II expansion, Saucito is becoming one of the Group’s most important assets, critical to achieving our 2018 production target of 65 moz silver. Produced 47% of the Group’s total silver (FY15), generating 29.6% of total adjusted revenue

Perfomance Highlights - 4Q17
- Annual silver production decreased vs. 2016 as a result of expected lower ore grade due to: i) higher grade development ore from West and Central areas at the Jarillas vein extracted in 2016; ii) restricted access to high grade sectors in Jarillas West area resulting from anchoring activities to avoid rock instability; primary reason for not reaching silver ore grade guidance of 290 g/t.
- Higher volume of ore processed from the Mezquite and Saucito veins partially offset expected lower annual silver ore grade.
- 2018 expected silver ore grade approx. 285 g/t due to regained access to higher ore grade areas at Jarillas West zone now rock stability issue resolved.
- Quarterly silver production remained at similar levels vs. 4Q16 as higher recovery rate and higher volume of ore processed offset unfavorable effect of lower ore grade. Quarterly silver production increased 7.2% vs. 3Q17 as a result of higher volume of ore processed due to additional ore mined from development areas and higher ore grade.
- Annual and quarterly by-product gold production decreased (vs. 2016) primarily as a result of lower ore grade, partially offset by higher volume of ore processed. Similarly, quarterly by-product gold production decreased -4.8% vs. 3Q17 as a result of lower recovery rate and ore grade; reduction partially compensated by higher volume of ore processed. 2018 gold grade expected to increase to 1.2 g/t.
- Annual by-product lead production decreased vs. 2016 as a result of lower ore grade and to a lesser extent, lower recovery rate, partially offset by higher ore processed. Quarterly by-product lead production decreased vs. 4Q16 and 3Q17 due to lower ore grade.
- Annual and quarterly by-product zinc production decreased vs. 2016, 4Q16 and 3Q17 as a result of lower ore grade.
Perfomance Highlights - FY17
- Advanced preparation work for the deepening of the Jarillas shaft
- Successfully converted resources into reserves while also increasing resource base (reserves up 8.1% & resources up 21.9%)
Performance Targets - 2018
- Maintain development rates
- Initiate deepening of the Jarillas shaft
- Intensify exploration to the south
