Yes. We ran into a couple of issues that happened. In the first quarter, we got behind on some of the development. So, we mined a high proportion of lower grade stopes to higher grade stopes during the first quarter and that was the problem there. We subsequently worked on that with regards to accelerating our development work and are getting back on schedule with regards to that. However, as we were mining some of the higher-grade stopes in the second quarter, one in particular, which was a quite important stope for us in the second quarter, we encountered some over break, some significant over break with regards to some of the work that we did there and that resulted in dilution of the stope. Bear in mind, when we start getting into grades that are 4%, 5%, 6%, that material becomes quite friable and some of the wall rock surrounding it remains that way as well. So, when we do get into these very high areas, as much as we try to be as careful as we can be with regards to our blocking patterns, et cetera. On occasion, not all the time, on occasion, we will see over break occurring and dilution occur. Now the interesting thing about it, the dilution was actually coming in around about 1.2% copper so it was still reasonable copper grades but our expectation on that stope was to have grades significantly higher coming into the mill than that lower grade. So ultimately, we will recover all of that copper material. Unfortunately, it's just not going to be at the same highest grade as we expected to come out in the second quarter. As we've gone into the third quarter, we have seen some of the stopes that we've targeted in terms of higher grade come into production. In general, we've had a pretty good start to the third quarter, albeit with regards to the accident last week, we did shut operations for three days as a result of the investigation but also with respect to the families and allowing our workforce to attend the funeral of our colleague. So, we've had a reasonably good start to the third quarter and we expect August and September to continue on track.
