Sure. Thank you very much for your questions, Andreas. Well, on the how -- please keep in mind that in 2020 -- in 2019, in May, we initiated the production of the second concentrator of Toquepala. So in 2019, we had 8 months of production of a new facility that has a capacity of 100,000 tons of copper per year. And in 2020, we had that facility running at full speed through the whole year, 12 months. Now as I mentioned a while ago, we -- at the beginning of the pandemic, we cut everything that we could in order to maintain only the concentrators, the smelter, the refinery and the SX-EW operations moving forward.
In the case of Peru, we were authorized given that our operations are isolated, and we have no cases of COVID at that point at the beginning of the pandemic. We have -- for quite a few months we've been where we didn't have -- most of the year, I would say, we didn't have any outbreaks of COVID inside the premises where our workers and their families live. We had some cases of people that were not staying at the premises, but living say in their houses in Moquegua or Ilo or Tacna.
So we managed to produce the mineral that our concentrators require. We didn't do any stripping -- any specific stripping works for Toquepala, very little, just necessary to extract the mineral. And that allowed us to maintain our production level while having no cases inside our premises, and having our production to hold. And as I say, we had at the beginning of 2019 in May, in the first -- the second quarter of 2019, we initiated production with the new concentrator of Toquepala. And we had a full year of production, and that explains why we increased our production in 2020 of copper concentrate and copper containing concentrate in this year -- last year.
Now regarding your question on possible expropriation of mining operations, well, the candidate that expressed that has indicated recently that he is considering more a change in taxation than a change for an expropriation of operations. So we actually don't think that this is going to be a material -- a thing that will be materialized. But as I say, we will see as we have a new president and this person takes the measures that he or she believes are the appropriate one for the country.
