2Q20

  • Quarterly silver production up 14.8% vs. 1Q20 as a result of higher ore grade due to a combination of incremental improvements achieved following implementation of action plan, as set out at end of last year and described below.

  • Quarterly silver production increased 4.5% vs. 2Q19 driven by a higher ore grade for reasons mentioned above, offset by a lower voume of ore processed due to workforce constraints resulting from the COVID-19 contingency.

  • First half silver production increased 5.5% vs. 1H19 due to higher ore grade, as we continue to implement action plan.

  • Our performance improvement plan, as set out on the Capital Markets Day in December 2019, continues to be implemented, focusing on controlling dilution, enhancing blasting and drilling techniques to cope with the narrower veins. All the long haul drilling stopes have now been scanned. Further, intiatives to increase efficiency and reduce downtime have been advanced, with semi-automatic drilling machines now operating.

  • Development rates remained at a similar level vs. 1Q20, with an average of 3,183m per month in 2Q20 (1Q20: 3,200m per month), despite a reduction in the number of contractors and employees on site while they self isolated in accordance to COVID-19 guidelines. During the first half, development rates increased 6.3% (3,190m per month) vs. 1H19 (3,000m per month) as a result of the ramp up of the tunnel boring machine and the new contractor hired at the end of 2019. With these measures and assuming COVID-19 evolution does not worsen, we remain confident of hitting our expected development rates of 3,400m per month by the end of 2020.

  • Quarterly by-product gold production increased 23.3% vs. 1Q20 driven by a higher ore grade.

  • Quarterly and first half by-product gold production decreased 19.7% and 21.4% vs. 2Q19 and 1H19 respectively due to lower ore grades and to a lesser extent, lower recovery rates.
  • Silver ore grade 2020 continues to be in range of 185-200 g/t, gold ore grade estimated to remain around 0.7 g/t.

FY19

  • Operational action plan developed and implemented

  • Development rates improved - 3,026m/m

  • Peruvian contractor hired at year end

  • Tunnel Boring Machine (TBM) commissioned at year end

  • 126,000 metres of infill drilling carried out

  • Deeping of the San Carlos shaft continued, on track to be concluded end of 2020

2020 Priorities

  • Infill drilling programme to continue (84-90 mts).
  • Development rates to be improved; target 3,500 - 3,800 m/m by year end
  • Dilution expected to decrese to 34%
  • Continue implementing initiatives to increase productivity and efficiency
  • Ramp up TBM in 1Q20 and targeting and average 300 m/m thereafter
  • Conclude the deepening of the San Carlos shaft by year end; access 56% of Fresnillo reserves
  • Commission the tailings flotation plant in 2H20 (Pyrites plant project phase II)
  • Conclude 2nd stage of beneficiation plant expansion, installation of flotation cells
