Okay. What you're referring to, John, is the smelter contracts and the TCs that were charged for having our material smelted at the smelters. Last year, there was a very, very big squeeze on smelter space and prices went through the roof. The smelters were able to charge almost anything they wanted, and they were near historic highs. That hit us very hard. They've come back to normality this year. Kim talked about it in her remarks.
But zinc, because we do produce a lot of zinc, hit us pretty hard. But the indications are right now, based on our current contract and spot, it will be reduced, on a per tonne of concentrate basis, about 30% in our TCs. That is a very significant number. I indicated to you that we are looking directionally at 19,000 or 20,000 tonnes of zinc. And if you have a 30% reduction of cost associated with that level of production, the math is pretty straightforward. It's a significant saving.
What we've done for our guidance and our budgeting purposes is we've taken a very, very conservative position for our pricing of all of our by-products. Just for example, we've used, directionally, just under $3 for copper. Copper is now north of $4. Zinc, we used $102, and zinc is trading $128, $130. Lead, we were high $70s and lead is a bit higher again right now. We were conservative on our numbers for silver and for gold.
Now gold, I'm going to make a comment on because we've seen a lot of volatility in price recently, who knows where it goes. But certainly, our by-products are looking very, very secure in terms of providing the cash flow we're anticipating. If anything, we'll get excess cash flow out of it.
Does that address it, John?
