• Zinc and copper in concentrate production decreased 32% and 44% Y-o-Y, impacted primarily by our
  Peruvian mines stoppage.
• Treated ore volume was down 43% with the suspension of Peruvian operations until mid-May, offsetting the strong performance of our Brazilian mines

• EBITDA decrease mainly driven by:
• • a negative variation of US$36 million from lower sales volumes and US$69 million price effect related to lower LME prices and changes in market prices in respect of quotation period adjustments;
  • the decrease in by-products revenue due to lower volume and LME prices.
• Positive impacts: lower operating costs and expenses, lower mineral exploration & project development spending, and U.S. dollar appreciation against Brazilian real. The decrease in corporate expenses also positively affected our results.

Aripuanã | Project

Competitive cash cost position with attractive returns

Project overview

• 13 years LOM¹ with excellent potential to extend mine life beyond 20 years2 based on current inferred resources and exploration drilling campaigns
• Zinc equivalent³ average production¹ 120kt/yr
• Sustainable project:
• • Tailings disposal: 50% dry stacks and 50% cement paste backfill
  • 100% process water recirculation, with minimal discharge to the environment

Highlights

• New rebaseline in progress and should be available during 2H20. The impact of COVID-19on the rebaseline and CAPEX continue to be assessed.
• Mobilization at the site at reduced pace due to COVID-19.
• Overall project physical progress reached 42.8% in July, 2020.
• 2Q20 CAPEX totaled US$46 million.
• For 2020, we revised our CAPEX to US$172 million.
• Mine Development reaching 3,618 meters in 2Q20 vs 2,444 meters in 1Q20.
• COVID-19protocols remains in place, i.e. antibody tests before mobilize people to Aripuanã.
