* "You should start to prospect for another vein of this ore" ''(between 1000 and 3000)''
* "The ore will run out soon" ''(between 100 and 1000)''
* "The ore will run out any hour" ''(less than 1-100)'' It's not yet clear what the messages are for the boundary values. For example, is exactly 100 ore "run out soon" or "run out any hour"?
