JIT and Silver Demand.
It never really occurred to me before but I was talking to a friend and mentioned Musk bought a silver mine to assure his many high tech companies would always have access to silver, but a very large part of silver demand is on a "just In Time" basis. When buyers panic they'll not only need silver for delivery tomorrow but for weeks and weeks. Each panicked buyer will need dozens of times more silver than they have in stock on a "normal" business day.
When the paper silver blows away it will expose massive demand.
