Maybe I'll speak high level to the impact of HPGR, and Joe can talk a little bit about the commissioning detail that might bring some clarity here. Where I'd start is that, when you look at the new Kisladag, our lead cycle from historic, the first decade and a half of operations, we had roughly a 90-day lead cycle and we got roughly 60% recovery. Looking forward with the new Kisladag, we're getting, with the HPGR, around 56% recovery, but we get that goal over a one-year period. So, it's a much slower lead cycle in the bottom part of this deposit. And that's what all the drilling and network we did over the last couple of years led us to these conclusions in a robust mine plan. So, this year, our productions is doing better than planned largely driven by tonnage, but the recoveries are as expected. So, this is good news for us. So, in terms of the detail, when you think about alright, we were at the beginning of the year expecting to be in commissioning in the third quarter, and that's slipped a little bit to the fourth-quarter. First thing I'd say is that's not too bad when you look at the impact COVID 's had on the planet. We've delivered a number of projects across our portfolio and dominantly Kisladag on budget and on schedule. And so, the HPGR is on budget. There was a slight slip in schedule due to delivery, but to me that's not bad news and the impact on production over 2021 and 2022, there is no impact. We've put that into our plan. So, there's a slight shift quarter-over-quarter, but it's a 1-year lease cycle. So yes, the impact will begin late Q4 and into next year, in terms of the downtime required to connect the HPGR and commission it. But overall, there's no negative impact here. We had a great year at Kisladag so far. We're going to finish strong. we're beating our guidance and we're set up to deliver what we promise for 2022. So high level, this is all positive. And maybe Joe can give a little color around the commission in detail.
