Could it be that MMI is waiting for DRV to release the next assay result in hopes that the market will react favourably to the results, consequently valuing DRV's SP higher? MMI would appear to have more cash in it's coffers if things were to go that way. As I understand it, MMI owns a great deal of DRV stock. Just food for thought.
I still do not have any extra money in my account, just MMI shares with $0 value fwiw.
