The whole point here is if the KGC put down the mega "depositories" or "vaults" with stacks of treasure in them. The only source for this information seems to be Orvus Howk and the black book, both being very dubious sources for real information. Howk was a lier and con man and was making up stuff faster than it could be written down.
There is no other source of information that even alludes to any mega treasures put down by the KGC. We all know that they existed and what their intentions were but they didn't accomplish their main goal and that was mainly because of a lack of funds. Why would the KGC be putting massive amounts of silver and gold (and copper if you believe Howk) in the ground when the South was having to borrow money from France? If their goal was to take over more land and help with the Civil War at the same time don't you think if they actually had any real money they would be putting it into the ongoing effort instead of putting it in the ground?
