Neumeyer may be wishing to withhold product from market and thus raise the price but him acting alone would only bankrupt First Majestic. What is needed is several major producers or most smaller ones to participate. Quantity has influence, while loners die by the way side.
The problem is that not enough silver miners have enough courage to join up and withhold, or at least reduce, amount of silver reaching the markets and thus force the market to react to supply.
Unlike gold, silver is needed industrially so paper silver and manipulated futures should not determine price, physical delivery must rule here.
Somehow those withholding need to be able to survive to the time that their influence is felt and reflected by the markets. That is fundamental to such a cartel.
So collectively all participants need to find enough capital to see them through the lean times. Tough if you are late to finance yourself and your share price has gone down due to economy and you are about to reduce your own sales.
Understandably I wish them luck.
