Yeah, those two have been found. They know exactly where they are. Unfortunately, residences and farms have been built over them in the intervening decades and it is thought that any attempt to disarm the charges will cause them to detonate as the explosives have likely gone unstable.
They’re hoping that they will degrade to the point where they go inert in the next few decades.
