Certainly. Thank you very much, Alfonso. Okay. On the cash cost, so we had an unusual fourth quarter in terms of cost and cash cost specifically that we believe it's an -- just an event. It's just something that we have some extra costs for certain repairs that usually are spread through the year, and we had to address them at the end of -- or during the fourth quarter. That created an increase in our cash costs for the quarter.
Our current expectation for the next year is to have cash cost even lower than what we have in full for 2019. Currently, our view is to have cash cost for next year of $0.81 per pound that will be formed as follows. The cost before any credits will be $1.52. That's pretty much in line with what we had in 2019, but we will have much more credits than what we had in this year of about $0.71 per pound. That will, when you do the subtraction, leaves you with $0.81 per pound of copper.
We are still working on how can we support and maintain this cash cost for the following years. We had a reduction in ore grades for molybdenum in 2021. Even though we will be producing much more zinc in 2021, we're expecting to have a higher cash cost in the range of $0.90 for that year. And well, as you heard, we have -- we are postponing slightly the start-up of the projects that we are undertaking right now and that will certainly influence the cash costs for the long term. For now, for 2020, as I say, it's expected $0.21, about $0.90 for 2021. And then depending on when the new projects will get in, we'll be having a better view on cash costs.
So question number two, update of growth opportunities. Well, basically, why the delay on the projects, particularly to reach the 1.5 million ton goal that we have right now? And we have done, through 2019, a major overview on our projects and established -- given the advancement that we have in some of them and the news that we're getting from the test and studies that we're doing, we updated the view. And as a result, basically, we are moving a little bit our goal for 1.5 million tons, from 2026, which was our first goal or the past goal, to 2028.
In terms of the legal situation in the San Martin mine, we're currently very confident that the company will prevail. The news that we have are relatively positive, and we are expecting it to be in operation at full capacity as it is getting now. So we have nothing important to report in this regard.
