Let me -- I'll take a bit of a higher level view and give a context around them, because we expect a number of questions on this. So we have three or four new facts at Round Mountain, on the negative, this Zone of Influence that clay layer that led us to have to lay the wall slopes more shallower in the north area, it would appear that the Zone of Influence of that clay layer now extends more to the West as well. So there will be a more extensive area, then we had previously thought where we have to lay the slopes back. However, on the plus side, we've added a million ounces here a Phase S, which is a little bit more than we were expecting, and the results are a little bit better than we expected. And on the exploration side, we're hitting some really great holes down in Phase X. And as we look at Phase X, it would certainly be an underground opportunity. If we go to Phase X anyway, as an underground, it would then make sense to access portions of Phase W, the higher grade portions of Phase W from an underground. So this is a multivariate optimization where we have to trade off slopes, Phase S, how we get sequence into the mine plan? And what does a potential underground scenario at X look like? But to answer your question, we're still looking at to 250 to 300 at Round Mountain, 2020 to 2023 and into 2024. And that's what the number baked into our guidance. Now would be on 2025, the level of production will depend on those three things. Do we split Phase W? And do we access some of the material underground. So let me just give the high level example on that. If we decide to visit S, if we decide to access some of Phase W from underground, we would do so at a higher cut off. And there would be fewer ounces in the near term. However, an underground would then allow us to go after ounces in W that are currently outside the 1,200 NMV. And indeed the $1,600 pit shell. So there may be a reduction in production in what were previously can be high years. But there would be ounces that come with much lower capital development costs. And we would make these decisions on an economic trade-off. So we would look for neutral economics or even improved economics. And we would trade-off the capital requirements. But I can't say with any degree of certainty right now, because these are subject of the optimization study that we're carrying out.
Q – Josh Wolfson: Okay. And when you're thinking about the reserves there, I cannot read the exact details. But there was some reconciliation opportunity, if I recall that -- are these factors -- are these outside opportunities that were outstanding still available going forward, are they faced into the reserve.
