Thank you, Carlos, and good morning to all. I will give you a brief introduction to our year-end results, and then turn the call to Luis, who will take you through the financial statements. After that, we'll open the call for questions and answers. The 2017 results show record production in both silver and gold. On a consolidated basis, silver production was 8.5 million ounces and our gold production was 56,400 ounces, 15% and 21% above 2016 as shown in slide 4 of the presentation. When compared against our annual guidance, silver was up 4% and gold production at 8%. In slide 5, we show that precious metals contribution to sales was 73% in the year. The balance is comprised by base metals. Year-over-year realized prices for silver and gold remained essentially the same. It was a different story with our zinc and lead by-products, higher metal prices for both metals and improved commercial terms for the sale of concentrates meant a year-over-year increment of net realized prices of 71% for zinc and 47% for lead. This was particularly relevant for the economic performance of our Caylloma mine this year. In slide 6, 2017 shows a record financial performance across our main financial metrics. Sales were $268.1 million, 27% above the prior year. Net income of $66.3 million 270% above our prior year, while earnings per share were $0.42 compared to $0.13 in 2016. Adjusted EBITDA was $122 million yielding an EBITDA margin of 46% and 40% above EBITDA over the prior year. Our net income carries a $31 million impairment reversal at Caylloma derived from successful exploration programs which led to the expansion of resource. Adjusted net income was $48.6 million for the year. In slide 7, our consolidated all-in sustaining cash cost per ounce of silver net of by-product credits was $6.40 a reduction of 24% compared to the prior year and also 35% below 2017 guidance. Our all-in sustaining cost benefitted mainly from higher precious metals production, higher base metal prices and improved commercial terms for the sale for concentrates. Moving on to capital investments in slide 8. Our consolidated CapEx for the year was $49.4 million. This includes $11.4 million of non-sustaining CapEx comprised mainly of $9 million for Lindero project reconstruction. $10.1 million of brownfields explorations and $28 million of sustaining capital at our mines. In slide 10, in our Lindero project is in the early stages of construction and shows 7% progress at the end of February 2018 against the target of 10%. Our main milestones are detailed engineering which is advancing according to schedule and purchase orders for mine fleet and other key equipment has been placed in January. The municipal construction permit from Tolar Grande was granted in February and Pioneer -- for initial work was scheduled to be completed at the end of March. In slide 11, the Lindero project remains on track for commissioning in the end of through the second quarter of 2019. Start of mass earthworks has been reprogrammed for April to allow local contractors to participate via contortion in this large and significant activity of the project. This was a strategic consideration for the project and there is no impact on our critical task for commissioning in Q2 2019. In slide 12, our brownfields exploration programs at Caylloma and San Jose carried 54,000 meters drilling in 2017 at a cost of approximately $10 million. It is worth noting, our focus on San Jose drilling for 2018, we're expanding the program from 25000 meters in 2017 to 45000 meters in 2018. In 2018, you will see us active in new exploration, new project initiatives throughout or strategic investments and the rig exploration in Mexico Argentina and Serbia. In Mexico, through investment in Prospero Silver, where we retained the option to select the property for a joint venture. We are satisfied with the work carried by Prospero throughout 2017 which has led to the identification of a large gold and silver at the thermal system at the Pachuca project. In Serbia, in joint venture with Medgold, we're waiting for surface access to initiate drilling the spring at the [indiscernible] project in the central Macedonian belt. And in Argentina, we're very active in early stage exploration with focus in the province of Salta. Here we have already auctioned two properties from private local parties, we aim to drill this first half of the year at the thermal, silver and gold targets. So, with that, I'll let Luis take your through the financial statements now.
