Yes they do, but that's not where the massive void in supply is coming from. Somehow the 200+ Moz deficits are being met, otherwise we wouldn't see a multi-year slump in the price at the same time as multi-year deficits. The source of the supply has to be from a place that isn't required to provide records publicly, otherwise it would be recorded in the silver surveys... Much like Government Sales were prior to 2016.
