100 floors. Every tenth has a health drink from Gale on it. Gale can be found on random floors at random times. I won't force you to RNG what you find. I won't do the system at all. However, I expect you to find no more then four junk ores, three metal ores, two silver ores, or one gold ores. You can't earn two silver ores unless you've had two floors without anything, and you can't find a gold ore without four floors without anything. You can find gems here and there.
