A couple weekends ago I mined multiple times for short stretches, and noticed that one particular spot always gave valorite ore in large quantities each time I mined the spot. I'm guessing I probably mined there 15 times during that stretch. I tried that spot again the following Monday and it produced only iron ore (wasn't using a prospector's tool or gargoyle pick during any of these attempts). It has continued to produce only iron ore since then, which got me to wondering about the randomness of colored ore. Has anyone figured out the pattern of the randomness? On other occasions I've mined a spot two consecutive times (after allowing time for the ore to replenish) and gotten different ore each time. Then this time a spot produced the same high level ore for two days straight. Mostly this is a curiosity question - not really expecting a cut and dry answer.
