Thank you, Tito. And good morning, everyone. On Page 7 we have our first quarter consolidated results. Beginning with the first chart on the left regarding mine production. We've had higher treated ore volumes, supporting a 3% increase of our zinc production year-over-year, partially offsetting lower zinc rate. Our Cerro Lindo mine had a better performance after all mine development initiatives carried out since last year. On copper, we ran into copper contaminants in the mining process and the copper production was also affected, decreasing 15% when compared to the first quarter of 2018. On the smelting side. In the first quarter of 2019 sales were relatively stable as you can see on this second graph from the left. And we continue to see a stable operational performance in our three smelters. In Peru, Nexa Cajamarquilla is increasing production year-over-year and has built up inventory in anticipation of our planned shutdown in the second half of the year when we will convert the plant process back to Jarosite. In Brazil, Tres Marias' production was affected by technical issues in the purification process in January, which was partially offset by better performance of the roaster in Juiz de Fora. On the next graph, mainly as a result of lower LME prices, Nexa's revenues were down 16% compared to one year ago. Adjusted EBITDA then totaled $108 million in the quarter, driven by lower revenues and higher mining costs, which were partially offset by the Brazilian real depreciation against the dollar. Looking forward, we're confident that our mining plan is on track and that we will deliver both our annual production and sales guidances. Let's please move to Slide 8. Regarding our debt profile and cash position, we continue to report a healthy balance sheet with extended debt profile and low leverage. As of March 31, the average maturity of our total debt was 5.9 years with an average cost of 4.8% per annum in U.S. dollar terms. On the pie charts on the lower left you can see the debt breakdown both in terms of category and currency. This profile remains unchanged from previous periods. On the right side we show net debt increasing from December 2018, mainly due to the reduction in our cash position. This was caused mainly by working capital changes as well as dividend payments, which I will explain in more details when describing the cash flow. As a result, at the bottom you can see our financial leverage measured by net debt to last 12 months adjusted EBITDA ratio, which stood at 1.07 times, an increase compared to the 0.5 times reported last quarter. Let's please move now to Slide 9. Here on this page you can see the breakdown of our $65 million CapEx, both by category and segment. We confirm our guidance of $420 million for the year. With regard to OpEx, which amount to $20 million, we continue our efforts to increase reserves and resources, aiming an average life of mine of 12 years for our current operations and also confirm guidance of $128 million for the year. Next, please go to the following, Slide 10. On this slide we demonstrate the free cash flow generation of Nexa. In the first quarter our EBITDA was $108 million. Negative working capital change was $112 million. Considering the usual payments we have tax, sustaining CapEx, and interest paid, free cash flow before dividends was negative in $63 million. It's worth mentioning working capital was affected by some very specific events, namely payments to suppliers and bonuses to employees related to the year of 2018 and increasing inventories of Cajamarquilla in anticipation for the maintenance stoppage to finalize the Jarosite conversion. Excluding these effects, working capital would have been around $29 million and operational cash flow would have been positive in $20 million. Finally, as a result of our commitment to our expansion projects which will contribute to additional cash generation in the future, as well as our practice of returning capital to the shareholders Nexa recorded a negative free cash flow of $169 million in the first quarter of 2019. Let's us move to Page 11. Regarding mining performance in the quarter, as already mentioned, treated ore volume increased to 5.5% year-over-year and production of contained zinc was 3% higher compared to the first quarter of 2018, mainly driven by Cerro Lindo's production up 14% year-over-year as there was an increase in both treated ore and zinc grade on the site. Guidance volumes are maintained. Net revenue for the mining segment amounted to $272 million, down 17% year-over-year primarily as a result of lower average zinc, lead and copper prices less than compensated by an increase of the zinc production volume. Financially, adjusted EBITDA for the mining segment amounted to $82.5 million in the quarter, 48% lower than the previous year, compounded both by the mentioned decrease of net revenues as well as higher production costs in Peru. These impacts were partially offset by the depreciation of the Brazilian currency, positively impacting costs in Brazil. And such, cash costs net of byproducts credits increased to $881 dollars per ton caused mainly by the increase of process volumes, as well as less by-products credits at Cerro Lindo and [indiscernible]. Moving to Slide 12. We represent our smelting segment performance. The sales volume of metallic zinc in the first quarter remains relatively stable compared to the first quarter of 2018. Our smelting business had a benefit of the flexibility of its sales strategy. With the economic slowdown in Argentina and maintenance shutdown of two main customers in Peru we're able to redirect our sales to Brazil as well as other regions. Thus, guidance for smelting is also maintained. Additionally, adjusted EBITDA for smelting amounted $26 million, down 14% on the same quarter of last year, impacted mainly by the drop in zinc metal prices year-over-year. This effect was partially offset by FX related gains in Brazil and higher treatment charges. On the other hand, the same effects of lower LME prices in the Brazilian real devaluation caused smelting cash cost to improve by 20%. Now I would like to hand over to Tito for his final remarks.
